Purpose To evaluate the efficacy and safety of intravitreal sirolimus in the management of noninfectious uveitis of the posterior segment (NIU-PS). Design Combined analysis of 2 phase 3, randomized, double-masked, multinational, 6-month studies. Participants Adults with active NIU-PS (intermediate uveitis, posterior uveitis, or panuveitis; defined as vitreous haze [VH] ≥1.5+ on modified Standardization of Uveitis Nomenclature scale). Methods Patients were randomized 1:1:1 to receive intravitreal sirolimus 44 μg (n = 208), 440 μg (n = 208), or 880 μg (n = 177) on days 1, 60, and 120. Patients discontinued medications for NIU-PS except for systemic corticosteroids, which were tapered according to protocol. Enrollment in the 880-μg group was terminated after interim results found no significant difference in efficacy compared with the 440-μg dose. Main Outcome Measures The primary efficacy end point was the percentage of patients with VH of 0 at month 5 in the study eye without the use of rescue therapy. Secondary efficacy end points included VH of 0 or 0.5+, corticosteroid-tapering success, and changes in best-corrected visual acuity (BCVA). Safety measures included ocular and nonocular adverse events. Results A total of 592 patients were randomized. Significantly higher proportions of patients treated with 440 μg compared with 44 μg intravitreal sirolimus achieved VH of 0 (21.2% vs. 13.5%; P = 0.038) and VH of 0 or 0.5+ (50.0% vs. 40.4%; P = 0.049) at month 5. Best-corrected visual acuity was stable (absolute change 5 letters in 80.1% and 80.2% of patients in the 440-μg and 44-μg groups, respectively. At month 5, corticosteroids were tapered successfully in 69.6% and 68.8% of patients in the 440-μg and 44-μg groups, and among these patients, VH of 0 or 0.5+ was achieved by 43.5% and 28.1% in the 440-μg and 44-μg groups. Both doses were generally well tolerated. Mean changes from baseline intraocular pressure (IOP) in the study eye at each analysis visit were minimal in all treatment groups. Conclusions Intravitreal sirolimus 440 μg improved ocular inflammation, as measured by VH, compared with the 44-μg dose, with minimal impact on IOP, while preserving BCVA.

PURPOSE: Assess systemic vascular endothelial growth factor-A (VEGF) levels after treatment with intravitreous aflibercept, bevacizumab or ranibizumab. DESIGN: Comparative-effectiveness trial with participants randomly assigned to 2-mg aflibercept, 1.25-mg bevacizumab, or 0.3-mg ranibizumab following a retreatment algorithm. PARTICIPANTS: Participants with available plasma samples (N=436) METHODS: Plasma samples were collected before injections at baseline, 4-week, 52-week and 104-week visits. In a pre-planned secondary analysis, systemic free-VEGF levels from an ELISA immunoassay were compared across anti-VEGF agents and correlated with systemic side effects. MAIN OUTCOME MEASURES: Changes in the natural log (ln) of plasma VEGF levels. RESULTS: Baseline free-VEGF levels were similar across all 3 groups. At 4 weeks, mean ln(VEGF) changes were −0.30±0.61, −0.31±0.54, −0.02±0.44 pg/ml for the aflibercept, bevacizumab, and ranibizumab groups, respectively. The adjusted differences between treatment groups (adjusted CI; P-value) were −0.01 (−0.12, +0.10; P=0.89), −0.31 (−0.44, −0.18; P

IMPORTANCE: Proactive treatment of nonproliferative diabetic retinopathy (NPDR) reduces the risk of progression to vision-threatening complications. OBJECTIVE: To evaluate vascular endothelial growth factor blockade therapy with intravitreal aflibercept injections in eyes with severe NPDR without diabetic macular edema (DME). DESIGN, SETTING, AND PARTICIPANTS: The Study of the Efficacy and Safety of Intravitreal Aflibercept for the Improvement of Moderately Severe to Severe Nonproliferative Diabetic Retinopathy (PANORAMA) was a double-masked 100-week randomized clinical trial conducted in multiple centers worldwide. The study included 402 adults with Diabetic Retinopathy Severity Scale (DRSS) level 47 or 53 with no DME and best-corrected visual acuity of 20/40 or better. INTERVENTIONS: Intravitreal injections of aflibercept, 2 mg, every 16 weeks after 3 initial monthly doses and one 8-week interval (aflibercept 2q16 group); intravitreal injections of aflibercept, 2 mg, every 8 weeks after 5 initial monthly doses, with pro re nata (PRN) dosing beginning at week 56 (aflibercept 2q8/PRN group); or sham injections (control group). MAIN OUTCOMES AND MEASURES: Proportions of eyes with a 2-step or greater improvement in DRSS level, vision-threatening complications, and center-involved DME from baseline to weeks 24, 52, and 100. RESULTS: Among 402 participants (1 eye per participant), the mean (SD) age was 55.7 (10.5) years; 225 (56.0%) were male, and 310 (77.1%) were White. A total of 135 were randomized to the aflibercept 2q16 group, 134 to the aflibercept 2q8/PRN group, and 133 to the control group. At 24 weeks, treatment with aflibercept resulted in a 2-step or greater improvement in DRSS level in 157 of 269 eyes (58.4%) in the combined aflibercept groups vs 8 of 133 eyes (6.0%) in the control group (adjusted difference, 52.3%; 95% CI, 45.2%-59.5%; P

Purpose To assess the long-term safety and vision change in patients who received intravitreal aflibercept injection (IAI) for neovascular age-related macular degeneration in an extension study after completing VIEW 1 trial. Design Prospective, open-label, multicenter, extension study. Participants Three hundred twenty-three patients. Methods In VIEW 1, 1217 patients were randomized to receive fixed dosing of 0.5 mg IAI every 4 weeks (0.5q4), 2 mg IAI every 4 weeks (2q4), 2 mg IAI every 8 weeks after 3 initial monthly dosing (2q8), or 0.5 mg ranibizumab every 4 weeks (Rq4) from baseline through week 52, followed by modified quarterly injections of the same dose of anti-vascular endothelial growth factor agent from weeks 52 to 96. After completing VIEW 1 at week 96, patients (n = 323) enrolled in an extension study and received 2 mg IAI on a modified quarterly injection schedule followed by at least an every 8-week dosing through week 212. Main Outcome Measures Long-term safety and vision change in patients followed for a median duration of 116 weeks in the extension study (total follow-up time of 212 weeks from the VIEW 1 baseline). Results Patients enrolled in the extension study gained a mean of 10.2 letters from the VIEW 1 baseline at week 96. These patients largely maintained vision over the extension study with a mean gain of 7.1 letters from the VIEW 1 baseline to week 212. The proportion of patients who lost ≥15 letters from the VIEW 1 extension baseline was 8.2% at week 212. Mean number of injections was 12.9 (range, 1–41) in the extension study. The most common serious ocular adverse event was endophthalmitis (0.9%). The overall incidence of Antiplatelet Trialists' Collaboration-defined arterial thromboembolic events was 6.2%. Conclusions Vision gains achieved with anti-vascular endothelial growth factor therapy in VIEW 1 were largely maintained by continued treatment with IAI 2 mg in the extension study. Anti-vascular endothelial growth factor injections (including 4 years of IAI 2 mg) were well-tolerated with no new safety signals compared with the known profile of IAI.

Background/aimsTo evaluate the long-term effects of treat-and-extend dosing of ranibizumab with and without navigated focal laser for diabetic macular oedema (DME).MethodsThis is a multicentre, randomised clinical trial where 150 eyes were randomised into three cohorts; Monthly (n=30), TReat and EXtend without macular laser photocoagulation (TREX; n=60), and treat and extend with angiography-GuIded macular LAser photocoagulation (GILA; n=60). During the first 2 years, eyes either received ranibizumab 0.3 mg every 4 weeks or underwent treat-and-extend ranibizumab with or without angiography-guided laser therapy. In the third year, all eyes were treated as needed with ranibizumab for >5 letters vision loss or if the central retinal thickness (CRT) was >325 µm, and all eyes were eligible to receive focal laser.Results109 eyes (73%) completed the 3-year end-point. At week 156, mean best-corrected visual acuity (BCVA) and CRT improved by 6.9, 9.7, 9.5 letters (p=0.60) and 129, 138, 165 µm (p=0.39), in the Monthly, TREX and GILA cohorts, respectively. These improvements were reached prior to week 104 and no significant changes occurred from week 104 to week 156 (BCVA: p=0.34; CRT: p=0.36). The mean number of injections in the third year was 3.0, 3.1, and 2.4 in the Monthly, TREX and GILA cohorts, respectively (p=0.56). 86 eyes (79%) required at least one ranibizumab injection in the third year.ConclusionThe improvements achieved after 2 years of treat-and-extend ranibizumab for DME were maintained in the third year with a mean of 3 intravitreal injections.Trial registration numberFDA IND 119146, NCT01934556.

Best-corrected visual acuity was stable (absolute change5 ETDRS letters) or improved5 letters in 80.1% and 80.2% of patients in the 440-μg and 44-μg groups, respectively. At month 5, corticosteroids were tapered successfully in 69.6% and 68.8% of patients in the 440-μg and 44-μg groups, and among these patients, VH of 0 or 0.5+ was achieved by 43.5% and 28.1% in the 440-μg and 44-μg groups. Both doses were generally well tolerated.

Purpose To compare monthly dosing with a treat and extend algorithm using ranibizumab 0.3 mg with and without angiography-guided macular laser photocoagulation for center-involving diabetic macular edema (DME). Design Multicenter, prospective, randomized clinical trial. Participants A total of 150 eyes from 116 subjects were randomized into 3 cohorts: Monthly (n = 30), TReat and EXtend without macular laser photocoagulation (TREX; n = 60), and treat and extend with angiography-GuIded macular LAser photocoagulation (GILA; n = 60). Methods Monthly cohort eyes received ranibizumab 0.3 mg every 4 weeks. Eyes in the TREX and GILA cohorts received 4 monthly injections of ranibizumab 0.3 mg followed by a treat and extend algorithm based on disease activity. Eyes in the GILA cohort also received angiography-guided macular laser photocoagulation at month 1 and again every 3 months for microaneurysm leakage. Main Outcome Measures Change in mean best-corrected visual acuity (BCVA), mean central retinal thickness (CRT), number of injections from baseline to 1 year, and percentage gaining/losing 2 and 3 lines of vision. Results Baseline demographics were well balanced among the cohorts. A total of 137 eyes (91%) completed the 1-year end point visit. At 1 year, the mean BCVA improved by 8.6, 9.6, and 9.5 letters in the Monthly, TREX, and GILA cohorts, respectively ( P = 0.8). There was no significant difference between the cohorts in the percentage gaining/losing 2 and 3 lines of vision. The CRT improved by 123 μm, 146 μm, and 166 μm in the Monthly, TREX, and GILA cohorts, respectively ( P = 0.47). The mean number of macular laser treatments in the GILA cohort at 1 year was 2.9 (range, 1–4). The number of injections was significantly reduced in both the TREX (10.7) and GILA (10.1) cohorts compared with the Monthly cohort (13.1, P Conclusions This prospective, randomized trial found that treat and extend dosing of ranibizumab 0.3 mg with and without angiography-guided macular laser photocoagulation significantly decreased the number of injections given while providing similar visual and anatomic outcomes compared with monthly dosing at 1 year. Adding angiography-guided laser photocoagulation to this dosing algorithm did not significantly improve outcomes at 1 year.

PurposeTo determine whether the efficacy and safety achieved with 2.0 mg intravitreal aflibercept injections (IAIs) for diabetic macular edema (DME) during the phase III VISTA DME trial were maintained with individualized, as-needed treatment.DesignPhase IV, multicenter, open-label extension study.MethodsSixty patients completing VISTA DME elected to enter the ENDURANCE extension study. All patients received IAIs in the presence of clinically relevant DME. Patients were observed at 4-, 8-, or 12-week intervals depending on the need for treatment. Main outcome measures were mean IAIs given through month 12 (M12), the proportion of patients receiving no IAIs, and the role of macular laser in decreasing treatment burden among patients requiring ongoing IAIs.ResultsA mean of 4.5 IAIs were administered through M12. Eighteen (30%) patients required no IAIs, and among those who met IAI retreatment criteria, a mean of 6.0 IAIs were administered through M12. Best-corrected visual acuity gains achieved during VISTA DME were maintained and stable with individualized dosing during ENDURANCE, fluctuating by

Purpose To evaluate the efficacy and safety of intravitreal sirolimus in the treatment of noninfectious uveitis (NIU) of the posterior segment (i.e., posterior, intermediate, or panuveitis). Design Phase III, randomized, double-masked, active-controlled, 6-month study with intravitreal sirolimus. Participants Adults with active NIU of the posterior segment (intermediate, posterior, or panuveitis), defined as a vitreous haze (VH) score >1+. Subjects discontinued NIU medications before baseline, except for systemic corticosteroids, which were allowed only for those already receiving them at baseline and were rapidly tapered after baseline per protocol. Methods Intravitreal sirolimus assigned 1:1:1 at doses of 44 (active control), 440, or 880 μg, administered on Days 1, 60, and 120. Main Outcome Measures The primary efficacy outcome was the percentage of subjects with VH 0 response at Month 5 (study eye) without use of rescue therapy. Secondary outcomes at Month 5 were VH 0 or 0.5+ response rate, corticosteroid tapering success rate (i.e., tapering to a prednisone-equivalent dosage of ≤5 mg/day), and changes in best-corrected visual acuity (BCVA). Adverse events during the double-masked treatment period are presented. Results A total of 347 subjects were randomized. Higher proportions of subjects in the intravitreal sirolimus 440 μg (22.8%; P = 0.025) and 880 μg (16.4%; P = 0.182) groups met the primary end point than in the 44 μg group (10.3%). Likewise, higher proportions of subjects in the 440 μg (52.6%; P = 0.008) and 880 μg (43.1%; P = 0.228) groups achieved a VH score of 0 or 0.5+ than in the 44 μg group (35.0%). Mean BCVA was maintained throughout the study in each dose group, and the majority of subjects receiving corticosteroids at baseline successfully tapered off corticosteroids (44 μg [63.6%], 440 μg [76.9%], and 880 μg [66.7%]). Adverse events in the treatment and active control groups were similar in incidence, and all doses were well tolerated. Conclusions Intravitreal sirolimus 440 μg demonstrated a significant improvement in ocular inflammation with preservation of BCVA in subjects with active NIU of the posterior segment.

To prospectively evaluate a treat and extend algorithm of ranibizumab with and without navigated laser to monthly dosing for center-involving diabetic macular edema.This was a multicenter, randomized, clinical trial.One hundred fifty eyes were randomized into 3 cohorts: monthly (n = 30), treat and extend without laser photocoagulation (TREX; n = 60), and treat and extend with angiography-guided laser photocoagulation (GILA; n = 60). Monthly cohort eyes received ranibizumab 0.3 mg every 4 weeks. TREX and GILA cohort eyes received 4 monthly injections of ranibizumab 0.3 mg followed by a treat and extend dosing strategy. GILA cohort eyes also received navigated focal laser at month 1 and again every 3 months as needed. The primary outcomes included the mean change in best-corrected visual acuity and central retinal thickness and the number of injections from baseline to 2 years.At 2 years, mean best-corrected visual acuity and central retinal thickness improved by 7.5, 9.6, and 9.0 letters (P = .75) and 139, 140, and 175 μm (P = .09), in the monthly, TREX, and GILA cohorts, respectively. The mean number of injections was significantly reduced in both the TREX (18.9) and GILA (17.5) cohorts compared with the monthly cohort (24.7, P.001). Between the TREX and GILA cohorts, there was no significant difference in the mean treatment interval, mean maximal treatment interval, or percentage of eyes extended to 12 weeks. The total 2-year incidence of Anti-Platelet Trialists' Collaboration events was 6.7%.The treat and extend algorithm of ranibizumab in the TREX-DME trial resulted in significantly fewer injections and yielded visual and anatomic gains comparable to monthly dosing at 2 years.

Purpose To determine week 52 efficacy and safety outcomes in eyes with macular edema after branch retinal vein occlusion (BRVO) treated with 2 mg intravitreal aflibercept injection (IAI) compared with grid laser. Design VIBRANT was a double-masked, randomized, phase 3 trial. Participants Eyes randomized and treated in VIBRANT were followed to week 52. Methods In the IAI group, eyes received IAI every 4 weeks through week 24 and IAI every 8 weeks through week 48 with rescue grid laser if needed at week 36. In the grid laser group, all eyes received grid laser at baseline and, if prespecified rescue criteria were met, 1 additional laser from week 12 to 20 and IAI every 8 weeks after 3 monthly doses from week 24 onward (the laser/IAI group). Main Outcome Measures The primary outcome measure was percentage of eyes with improvement from baseline best-corrected visual acuity (BCVA) letter score ≥15 at week 24. All outcome measures at week 52 were exploratory, and P values are considered nominal. Results The percentage of eyes with improvement from baseline letter score ≥15 in the IAI and laser/IAI groups was 52.7% versus 26.7% ( P = 0.0003) at week 24 and 57.1% versus 41.1% ( P = 0.0296) at week 52. The corresponding mean change from baseline BCVA letter score was 17.0 versus 6.9 ( P P = 0.0035) at week 52. The mean reduction from baseline central retinal thickness was 280.5 μm versus 128.0 μm ( P P = 0.0218) at week 52. In the IAI group, 10.6% of eyes received rescue laser at week 36, and in the laser/IAI group, 80.7% received rescue IAI from week 24 to week 48. Traumatic cataract in 1 eye (1.1%) in the IAI group was the only ocular serious adverse event. Conclusions After 6 monthly IAI, injections every 8 weeks maintained control of macular edema and visual benefits through week 52. In the laser group, rescue IAI given from week 24 onward resulted in substantial visual improvements at week 52.

Purpose: To report a case of panuveitis, retinal vasculitis, and optic disk granuloma due to sarcoidosis. Methods: Case report and literature review. Results: A 26-year-old previously healthy African American male presented with four months of gradual progressive visual decline in the right eye. Clinical examination revealed severe panuveitis, retinal vasculitis, and large optic nerve mass lesion. Diffuse supraclavicular lymphadenopathy was also present. Histopathologic examination of the lymph node biopsy revealed granulomatous inflammation with some areas of caseous necrosis consistent with sarcoidosis. Conclusion: Sarcoidosis is a common cause of uveitis and retinal vasculitis. In rare cases, an optic disk granuloma may occur and can be treated with immunosuppressive therapy.

The introduction of anti-vascular endothelial growth factor (anti-VEGF) drugs to ophthalmology has revolutionized the treatment of neovascular age-related macular degeneration (nAMD). Despite this significant progress, gaps and challenges persist in the diagnosis of nAMD, initiation of treatment, and management of frequent intravitreal injections. Thus, nAMD remains a leading cause of blindness in the United States.To present current knowledge, evidence, and expert perspectives on anti-VEGF therapies in nAMD to support managed care professionals and providers in decision making and collaborative strategies to overcome barriers to optimize anti-VEGF treatment outcomes among nAMD patients.Three anti-VEGF therapies currently form the mainstay of treatment for nAMD, including 2 therapies approved by the FDA for treatment of nAMD (aflibercept and ranibizumab) and 1 therapy approved by the FDA for oncology indications and used off-label for treatment of nAMD (bevacizumab). In clinical trials, each of the 3 agents maintained visual acuity (VA) in approximately 90% or more of nAMD patients over 2 years. However, in long-term and real-world settings, significant gaps and challenges in diagnosis, treatment, and management pose barriers to achieving optimal outcomes for patients with nAMD. Many considerations, including individual patient characteristics, on-label versus off-label treatment, repackaging, and financial considerations, add to the complexity of nAMD decision making and management. Many factors may contribute to additional challenges leading to suboptimal long-term outcomes among nAMD patients, such as delays in diagnosis and/or treatment approval and initiation, individual patient response to different anti-VEGF therapies, lapses in physician regimentation of anti-VEGF injection and monitoring, and inadequate patient adherence to treatment and monitoring. These latter factors highlight the considerable logistical, emotional, and financial burdens of long-term, frequent intravitreal injections and the vital importance of personalized approaches to anti-VEGF treatment decision making and management for patients with nAMD. To address these challenges and reduce the number of yearly injections, studies have examined alternative dosing regimens, including extended fixed intervals, as needed, and treat-and-extend strategies in specific nAMD patient populations. New clinical evidence and insights into expert clinical practice discussed in this article can support managed care professionals in the key role they play in addressing challenges in nAMD treatment and management and optimizing patient outcomes through appropriate management of anti-VEGF treatment.PRIME Education is an independent medical education company and has been an accredited provider of continuing education for 23 years.

Patients and methods: Patients were randomized to receive intravitreal aflibercept 2mg every 4weeks or sham injections until week 24. From week 24 to week 52, all intravitreal aflibercept-treated patients in both studies and sham-treated patients in COPERNICUS were eligible to receive intravitreal aflibercept based on prespecified criteria. In GALILEO, sham-treated patients continued to receive sham treatment through week 52. Results: At week 24, mean gain in best-corrected visual acuity and mean reduction in central retinal thickness were greater for intravitreal aflibercept-treated patients compared with sham, consistent with individual trial results. At week 52, after 6months of intravitreal aflibercept as-needed treatment in COPERNICUS, patients originally randomized to sham group experienced visual and anatomic improvements but did not improve to the extent of those initially treated with intravitreal aflibercept, while the sham group in GALILEO did not improve over week 24 mean best-corrected visual acuity scores.

Background/aimsTo evaluate the efficacy and safety of individualised 2.0 mg intravitreal aflibercept retreatment for diabetic macular oedema (DME) through the fifth year of management.MethodsThis is a phase IV, 2-year, open-label extension study. Sixty patients completing the 3-year VISTA DME (Study of Intravitreal Aflibercept Injection in Patients With Diabetic Macular Edema) phase III trial enrolled in the ENDURANCE (Long-Term Efficacy and Safety of Intravitreal Aflibercept for the Treatment of DME in Subjects Who Completed the VISTA DME Trial) extension study. All patients received aflibercept in the presence of clinically relevant DME. Intervals between visits were prescribed according to disease activity. The main outcome measure was mean aflibercept injections given through 2 years.ResultsA mean of 7.7 aflibercept injections were administered through 2 years. Fifteen (25%) patients required no retreatment and 48% (n=29) of patients received five or fewer injections through 2 years. Among patients who received at least one aflibercept retreatment during ENDURANCE, the mean number of injections through 2 years was 9.5. The mean visual acuity and central retinal thickness gains achieved during VISTA DME were maintained and stable during ENDURANCE. The most notable safety signal was progression of diabetic retinopathy. Six (10%) patients converted from non-proliferative to proliferative diabetic retinopathy (PDR), and a total of eight patients experienced PDR events occurring at a mean of 387 days following the previous aflibercept treatment.ConclusionThe need for aflibercept retreatment was substantially reduced in the fourth and fifth years of aflibercept dosing for DME following initiation of therapy in the VISTA DME trial. While vision gains achieved during the 3-year VISTA DME trial were maintained through ENDURANCE with a reduced treatment burden, clinically relevant worsening of diabetic retinopathy was observed with progression to PDR in 10% of the eyes.Trial registration numberNCT02299336

Background/AimsProspectively evaluate outcomes in the third year of neovascular age-related macular degeneration (AMD) management using ranibizumab with continued treat and extend (TREX) dosing compared with monthly visits with retreatment upon evidence of exudative disease activity (PRN, pro re nata).MethodsSubjects with treatment-naïve neovascular AMD were randomised 1:2 to Monthly or TREX and managed through 2 years. In the third year, subjects randomised to Monthly were managed PRN while subjects randomised to TREX were continued on TREX dosing or transitioned to PRN after achieving an interval of 12 weeks between visits.ResultsSixty subjects enrolled and 46 (77%) completed month 36 (M36). Transition from Monthly to PRN was associated with a decline in best corrected visual acuity (BCVA) (+10.5 letters (month 24) to +5.4 (M36, p=0.09)); three (15%) subjects required no dosing during year 3, and 47% (114/243) of possible PRN injections were delivered, yielding a mean of 6.1 injections during year 3. Among the 9 (23%) TREX subjects transitioned to PRN, the need for ongoing anti-vascular endothelial growth factor retreatments was small, with 4 (4%) intravitreal injections being delivered among 106 PRN visits; this subgroup displayed an inferior BCVA trajectory compared with the remainder of subjects. Outcomes among subjects continued on TREX were more favourable, with a mean gain of +5.0 letters at M36.ConclusionsUpon transition to PRN, subjects randomised to monthly dosing experienced a decline in BCVA. Among subjects initially randomised to TREX who transitioned to PRN after achieving a 12-week interval between visits, the overall need for additional treatment was low.Trial registration numberNCT01748292, Results.

Purpose To evaluate a prospective treat-and-extend (TREX) management strategy compared with monthly dosing with intravitreal ranibizumab (Lucentis) in neovascular age-related macular degeneration (AMD). Design Prospective, randomized, multicenter clinical trial. Participants Sixty patients with treatment-naive neovascular AMD randomized 1:2 to monthly or TREX cohorts. Methods Patients with Early Treatment Diabetic Retinopathy Study (ETDRS) best-corrected visual acuity (BCVA) of 20/32 to 20/500 (Snellen equivalent) were randomized to receive intravitreal 0.5 mg ranibizumab monthly or, according to a TREX protocol, no less frequently than every 12 weeks. After interval extension, if recurrent exudative disease was identified, this maximum interval between treatments was rechallenged according to a strict prospective protocol. Main Outcome Measure Change in ETDRS BCVA from baseline. Results Sixty patients were enrolled and 50 completed month 24, at which point mean ETDRS BCVA letter gains were similar: 10.5 and 8.7 for the monthly and TREX cohorts, respectively ( P = 0.64). At month 24, 4 patients (20%) and 12 patients (30%) in the monthly and TREX cohorts, respectively, gained at least 15 letters ( P = 0.41). No monthly cohort patient lost more than 2 letters, whereas 5 TREX cohort patients (13%) lost at least 15 letters. Anatomic improvements were similar between the cohorts. Through month 24, the mean number of injections administered was 25.5 (range, 22–27) and 18.6 (range, 10–25) for the monthly and TREX cohorts, respectively ( P Conclusions The TREX neovascular AMD management protocol used with ranibizumab in the Treat-and-Extend Protocol in Patients with Wet Age-Related Macular Degeneration (TREX-AMD) study resulted in visual and anatomic gains comparable with those obtained with monthly dosing, and most patients randomized to TREX therapy demonstrated a relatively consistent maximum extension interval.

To assess the long-term safety and vision change in patients who received intravitreal aflibercept injection (IAI) for neovascular age-related macular degeneration in an extension study after completing VIEW 1 trial.Prospective, open-label, multicenter, extension study.Three hundred twenty-three patients.In VIEW 1, 1217 patients were randomized to receive fixed dosing of 0.5 mg IAI every 4 weeks (0.5q4), 2 mg IAI every 4 weeks (2q4), 2 mg IAI every 8 weeks after 3 initial monthly dosing (2q8), or 0.5 mg ranibizumab every 4 weeks (Rq4) from baseline through week 52, followed by modified quarterly injections of the same dose of anti-vascular endothelial growth factor agent from weeks 52 to 96. After completing VIEW 1 at week 96, patients (n = 323) enrolled in an extension study and received 2 mg IAI on a modified quarterly injection schedule followed by at least an every 8-week dosing through week 212.Long-term safety and vision change in patients followed for a median duration of 116 weeks in the extension study (total follow-up time of 212 weeks from the VIEW 1 baseline).Patients enrolled in the extension study gained a mean of 10.2 letters from the VIEW 1 baseline at week 96. These patients largely maintained vision over the extension study with a mean gain of 7.1 letters from the VIEW 1 baseline to week 212. The proportion of patients who lost ≥15 letters from the VIEW 1 extension baseline was 8.2% at week 212. Mean number of injections was 12.9 (range, 1-41) in the extension study. The most common serious ocular adverse event was endophthalmitis (0.9%). The overall incidence of Antiplatelet Trialists' Collaboration-defined arterial thromboembolic events was 6.2%.Vision gains achieved with anti-vascular endothelial growth factor therapy in VIEW 1 were largely maintained by continued treatment with IAI 2 mg in the extension study. Anti-vascular endothelial growth factor injections (including 4 years of IAI 2 mg) were well-tolerated with no new safety signals compared with the known profile of IAI.

To evaluate a prospective treat-and-extend (TREX) management strategy compared with monthly dosing with intravitreal ranibizumab (Lucentis) in neovascular age-related macular degeneration (AMD).Prospective, randomized, multicenter clinical trial.Sixty patients with treatment-naïve neovascular AMD randomized 1:2 to monthly or TREX cohorts.Patients with Early Treatment Diabetic Retinopathy Study (ETDRS) best-corrected visual acuity (BCVA) of 20/32 to 20/500 (Snellen equivalent) were randomized to receive intravitreal 0.5 mg ranibizumab monthly or, according to a TREX protocol, no less frequently than every 12 weeks. After interval extension, if recurrent exudative disease was identified, this maximum interval between treatments was rechallenged according to a strict prospective protocol.Change in ETDRS BCVA from baseline.Sixty patients were enrolled and 50 completed month 24, at which point mean ETDRS BCVA letter gains were similar: 10.5 and 8.7 for the monthly and TREX cohorts, respectively (P = 0.64). At month 24, 4 patients (20%) and 12 patients (30%) in the monthly and TREX cohorts, respectively, gained at least 15 letters (P = 0.41). No monthly cohort patient lost more than 2 letters, whereas 5 TREX cohort patients (13%) lost at least 15 letters. Anatomic improvements were similar between the cohorts. Through month 24, the mean number of injections administered was 25.5 (range, 22-27) and 18.6 (range, 10-25) for the monthly and TREX cohorts, respectively (P 0.001). Among TREX patients completing month 24, 14 (47%) were at an extension interval of 8 weeks or more, and the mean maximum tolerated extension was 8.5 weeks over the course of 2 years. Of the 26 TREX patients (65%) who demonstrated recurrent exudation upon interval extension, the first maximum extension interval was consistent in most eyes (n = 19 [73%]).The TREX neovascular AMD management protocol used with ranibizumab in the Treat-and-Extend Protocol in Patients with Wet Age-Related Macular Degeneration (TREX-AMD) study resulted in visual and anatomic gains comparable with those obtained with monthly dosing, and most patients randomized to TREX therapy demonstrated a relatively consistent maximum extension interval.

To compare monthly dosing with a treat and extend algorithm using ranibizumab 0.3 mg with and without angiography-guided macular laser photocoagulation for center-involving diabetic macular edema (DME).Multicenter, prospective, randomized clinical trial.A total of 150 eyes from 116 subjects were randomized into 3 cohorts: Monthly (n = 30), TReat and EXtend without macular laser photocoagulation (TREX; n = 60), and treat and extend with angiography-GuIded macular LAser photocoagulation (GILA; n = 60).Monthly cohort eyes received ranibizumab 0.3 mg every 4 weeks. Eyes in the TREX and GILA cohorts received 4 monthly injections of ranibizumab 0.3 mg followed by a treat and extend algorithm based on disease activity. Eyes in the GILA cohort also received angiography-guided macular laser photocoagulation at month 1 and again every 3 months for microaneurysm leakage.Change in mean best-corrected visual acuity (BCVA), mean central retinal thickness (CRT), number of injections from baseline to 1 year, and percentage gaining/losing 2 and 3 lines of vision.Baseline demographics were well balanced among the cohorts. A total of 137 eyes (91%) completed the 1-year end point visit. At 1 year, the mean BCVA improved by 8.6, 9.6, and 9.5 letters in the Monthly, TREX, and GILA cohorts, respectively (P = 0.8). There was no significant difference between the cohorts in the percentage gaining/losing 2 and 3 lines of vision. The CRT improved by 123 μm, 146 μm, and 166 μm in the Monthly, TREX, and GILA cohorts, respectively (P = 0.47). The mean number of macular laser treatments in the GILA cohort at 1 year was 2.9 (range, 1-4). The number of injections was significantly reduced in both the TREX (10.7) and GILA (10.1) cohorts compared with the Monthly cohort (13.1, P0.001). There were no cases of endophthalmitis, and the total incidence of Anti-Platelet Trialists' Collaboration events was 4.7%.This prospective, randomized trial found that treat and extend dosing of ranibizumab 0.3 mg with and without angiography-guided macular laser photocoagulation significantly decreased the number of injections given while providing similar visual and anatomic outcomes compared with monthly dosing at 1 year. Adding angiography-guided laser photocoagulation to this dosing algorithm did not significantly improve outcomes at 1 year.

Objective To assess the efficacy and safety of intravitreal vascular endothelial growth factor (VEGF) Trap-Eye in eyes with macular edema secondary to central retinal vein occlusion (CRVO). Design Multicenter, randomized, prospective, controlled trial. Participants One hundred eighty-nine eyes with macular edema secondary to CRVO. Methods Eyes were randomized 3:2 to receive VEGF Trap-Eye 2 mg or sham injection monthly for 6 months. Main Outcome Measures The proportion of eyes with a ≥15-letter gain or more in best-corrected visual acuity (BCVA) at week 24 (primary efficacy end point), mean changes in BCVA and central retinal thickness (CRT), and proportion of eyes progressing to neovascularization of the anterior segment, optic disc, or elsewhere in the retina. Results At week 24, 56.1% of VEGF Trap-Eye treated eyes gained 15 letters or more from baseline versus 12.3% of sham-treated eyes ( P P P P = 0.006). Conjunctival hemorrhage, reduced visual acuity, and eye pain were the most common adverse events (AEs). Serious ocular AEs were reported by 3.5% of VEGF Trap-Eye patients and 13.5% of sham patients. Incidences of nonocular serious AEs generally were well balanced between both groups. Conclusions At 24 weeks, monthly intravitreal injection of VEGF Trap-Eye 2 mg in eyes with macular edema resulting from CRVO improved visual acuity and CRT, eliminated progression resulting from neovascularization, and was associated with a low rate of ocular AEs related to treatment.

To evaluate the association of subretinal hyperreflective material (SHRM) with visual acuity (VA), geographic atrophy (GA), and scar in the Comparison of Age-Related Macular Degeneration Treatments Trials (CATT).Prospective cohort study within a randomized clinical trial.The 1185 CATT participants.Masked readers graded scar and GA on fundus photography and fluorescein angiography and graded SHRM on time-domain and spectral-domain (SD) optical coherence tomography (OCT) throughout 104 weeks. Measurements of SHRM height and width in the fovea, within the center 1 mm(2), or outside the center 1mm(2) were obtained on SD OCT images at 56 (n = 76) and 104 (n = 66) weeks.Presence of SHRM, as well as location and size, and associations with VA, scar, and GA.Among CATT participants, the percentage with SHRM at enrollment was 77%, decreasing to 68% at 4 weeks after treatment and to 54% at 104 weeks. At 104 weeks, scar was present more often in eyes with persistent SHRM than in eyes with SHRM that resolved (64% vs. 31%; P0.0001). Among eyes with detailed evaluation of SHRM at weeks 56 (n = 76) and 104 (n = 66), mean VA letter score was 73.5 (standard error [SE], 2.8), 73.1 (SE, 3.4), 65.3 (SE, 3.5), and 63.9 (SE, 3.7) when SHRM was absent, present outside the central 1 mm(2), present within the central 1 mm(2) but not the foveal center, or present at the foveal center (P = 0.02), respectively. When SHRM was present, the median maximum height under the fovea, within the central 1 mm(2) including the fovea and anywhere within the scan, was 86 μm, 120 μm, and 122 μm, respectively. Visual acuity was decreased with greater SHRM height and width (P0.05).In eyes with neovascular age-related macular degeneration (AMD), SHRM is common and often persists after anti-vascular endothelial growth factor treatment. At 2 years, eyes with scar were more likely to have SHRM than other eyes. Greater SHRM dimensions were associated with worse VA. In eyes with neovascular AMD, SHRM is an important morphologic biomarker.

Purpose To evaluate the clinical and pathologic findings in two patients with prior breast carcinoma who underwent diagnostic vitrectomy for vitreous opacities and preretinal membrane. Methods The clinical histories and ophthalmic findings in two patients were reviewed. Vitrectomy specimens from the patients were processed by cytospin and standard tissue techniques, stained with hematoxylin and eosin, and examined immunohistochemically for cytokeratins. The original breast carcinoma specimens were reviewed. Results The vitreous in both patients contained malignant cells with cytologic features consistent with metastatic carcinoma. Immunohistochemical stains were positive for cytokeratins in the cells. The cytologic findings in the vitreous cells resembled the primary breast carcinoma. Conclusions Breast carcinoma may metastasize to the vitreous, most likely via the retina. The clinical manifestations include vitreous cell and preretinal membrane.

To compare the efficacy and safety of intravitreal aflibercept injection (IAI) with macular grid laser photocoagulation for the treatment of macular edema after branch retinal vein occlusion (BRVO).The VIBRANT study was a double-masked, active-controlled, randomized, phase III trial.Treatment-naïve eyes with macular edema after BRVO were included in the study if the occlusion occurred within 12 months and best-corrected visual acuity (BCVA) was between ≤73 and ≥24 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (20/40-20/320 Snellen equivalent).Eyes (1 eye per patient) received either IAI 2 mg every 4 weeks (n=91) from baseline to week 20 or grid laser (n=92) at baseline with a single grid laser rescue treatment, if needed, from weeks 12 through 20.The primary outcome measure was the proportion of eyes that gained ≥15 ETDRS letters from baseline BCVA at week 24. Secondary end points included mean change from baseline BCVA and central retinal thickness (CRT) at week 24.The proportion of eyes that gained ≥15 ETDRS letters from baseline at week 24 was 52.7% in the IAI group compared with 26.7% in the laser group (P=0.0003). The mean improvement from baseline BCVA at week 24 was 17.0 ETDRS letters in the IAI group and 6.9 ETDRS letters in the laser group (P0.0001). The mean reduction in CRT from baseline at week 24 was 280.5 μm in the IAI group and 128.0 μm in the laser group (P0.0001). Traumatic cataract in an IAI patient was the only ocular serious adverse event (SAE) that occurred. There were no cases of intraocular inflammation or endophthalmitis. The incidence of nonocular SAEs was 8.8% in the IAI group and 9.8% in the laser group. One Anti-Platelet Trialists' Collaboration-defined event of nonfatal stroke (1.1%) and 1 death (1.1%) due to pneumonia occurred during the 24 weeks of the study, both in patients in the laser group.Monthly IAI provided significantly greater visual benefit and reduction in CRT at 24 weeks than grid laser photocoagulation in eyes with macular edema after BRVO.

Purpose To report the treatment strategies and visual acuity outcomes of chronic postoperative endophthalmitis caused by Propionibacterium acnes. Design Retrospective noncomparative case series. Participants All patients presenting 8 or more weeks after cataract surgery with intraocular inflammation caused by culture-proven P. acnes infection and treated at two institutions from 1974 through 1996 were included. Methods Patients underwent three different initial treatment strategies. The study did not have a defined treatment protocol, but all patients received intraocular antibiotics. Patients were not randomly assigned to the various treatment strategies. Main outcome measures Final visual acuity and effectiveness of various treatment procedures either as initial or follow-up therapy were assessed. Results Using the 3 initial strategies, 36 patients were treated: (1) intraocular antibiotic injection alone (IOAB; n=12); (2) pars plana vitrectomy and IOAB injection (PPV; n=10); and (3) PPV with subtotal capsulectomy and IOAB injection (PPV-PC; n=14). The number of patients with recurrent or persistent inflammation after one of the three initial treatment strategies were as follows: (1) IOAB alone, 12 (100%); (2) PPV, 5 (50%); and (3) PPV-PC, 2 (14%). None of the patients that underwent subsequent PPV, total capsular bag removal, IOAB injection, and either intraocular lens (IOL) exchange or removal had persistent or recurrent intraocular inflammation. Overall, final visual acuity was 20/40 or better in 18 patients (50%), and a total of 28 patients (78%) retained 20/400 or better vision. The mean follow-up after the last treatment was 2.9 years. Conclusions In this series of chronic P. acnes endophthalmitis, initial treatment with IOAB injection alone or vitrectomy without capsulectomy was associated with high rates of recurrent or persistent intraocular inflammation. Pars plana vitrectomy, partial capsulectomy, and IOAB injection without IOL exchange was usually successful on long-term follow-up. In patients with recurrent intraocular inflammation, pars plana vitrectomy, total capsular bag removal, IOAB injection, and IOL exchange or removal was a uniformly successful strategy. In contrast to other types of postoperative endophthalmitis, IOL exchange can be considered in these patients after total capsular bag removal.

To evaluate the efficacy and safety of intravitreal aflibercept injection (IAI) for the treatment of macular edema secondary to central retinal vein occlusion (CRVO).Randomized, double-masked, phase 3 trial.A total of 188 patients with macular edema secondary to CRVO.Patients received IAI 2 mg (IAI 2Q4) (n = 114) or sham injections (n = 74) every 4 weeks up to week 24. During weeks 24 to 52, patients from both arms were evaluated monthly and received IAI as needed, or pro re nata (PRN) (IAI 2Q4 + PRN and sham + IAI PRN). During weeks 52 to 100, patients were evaluated at least quarterly and received IAI PRN.The primary efficacy end point was the proportion of patients who gained ≥ 15 letters in best-corrected visual acuity (BCVA) from baseline to week 24. This study reports week 100 results.The proportion of patients gaining ≥ 15 letters was 56.1% versus 12.3% (P0.001) at week 24, 55.3% versus 30.1% (P0.001) at week 52, and 49.1% versus 23.3% (P0.001) at week 100 in the IAI 2Q4 + PRN and sham + IAI PRN groups, respectively. The mean change from baseline BCVA was also significantly higher in the IAI 2Q4 + PRN group compared with the sham + IAI PRN group at week 24 (+17.3 vs. -4.0 letters; P0.001), week 52 (+16.2 vs. +3.8 letters; P0.001), and week 100 (+13.0 vs. +1.5 letters; P0.0001). The mean reduction from baseline in central retinal thickness was 457.2 versus 144.8 μm (P0.001) at week 24, 413.0 versus 381.8 μm at week 52 (P = 0.546), and 390.0 versus 343.3 μm at week 100 (P = 0.366) in the IAI 2Q4 + PRN and sham + IAI PRN groups, respectively. The mean number (standard deviation) of PRN injections in the IAI 2Q4 + PRN and sham + IAI PRN groups was 2.7 ± 1.7 versus 3.9 ± 2.0 during weeks 24 to 52 and 3.3 ± 2.1 versus 2.9 ± 2.0 during weeks 52 to 100, respectively. The most frequent ocular serious adverse event from baseline to week 100 was vitreous hemorrhage (0.9% vs. 6.8% in the IAI 2Q4 + PRN and sham + IAI PRN groups, respectively).The visual and anatomic improvements after fixed dosing through week 24 and PRN dosing with monthly monitoring from weeks 24 to 52 were diminished after continued PRN dosing, with a reduced monitoring frequency from weeks 52 to 100.

This study reports the expression of functional human lysyl hydroxylase (LH), a post-translational modifying enzyme that catalyzes the hydroxylation of the lysine residues essential for cross-linking in collagen biosynthesis. We have developed a novel baculovirus system for the expression of LH, a protein that exists normally within the lumen of the endoplasmic reticulum, using a powerful baculovirus signal sequence for secretion. The supernatant from Sf9 cells infected with the viral recombinant showed significant LH activity that increased linearly with supernatant concentration, whereas there was no detectable LH activity in the cell pellet. Silver staining of the fractions purified from the active supernatant by concanavalin A Sepharose chromatography and separated by sodium dodecylsulfate-polyacrylamide gel electrophoresis demonstrated an 85-kDa protein (the expected size of the LH subunit) that was most prominent in those fractions with the highest LH activity. N-terminal amino acid sequencing verified that the N-terminal primary structure of this 85-kDa protein was identical to human LH. Moreover, the activity of the expressed protein was shown to be dependent on the presence of Fe++, ascorbate, and alpha-ketoglutarate, three essential cofactors for LH activity. We have therefore successfully developed a novel expression system that produces functional human LH and enables this normally nonsecretory enzyme to be secreted, facilitating its separation from the intracellular proteins of insect cells. Future applications should allow characterization of the LH active site by crystallographic studies and site-directed mutagenesis for structure-function comparison.

To evaluate intravitreal aflibercept injections (IAI; also called VEGF Trap-Eye) for patients with macular edema secondary to central retinal vein occlusion (CRVO).Randomized controlled trial.This multicenter study randomized 189 patients (1 eye/patient) with macular edema secondary to CRVO to receive 6 monthly injections of either 2 mg intravitreal aflibercept (IAI 2Q4) (n = 115) or sham (n = 74). From week 24 to week 52, all patients received 2 mg intravitreal aflibercept as needed (IAI 2Q4 + PRN and sham + IAI PRN) according to retreatment criteria. The primary endpoint was the proportion of patients who gained ≥15 ETDRS letters from baseline at week 24. Additional endpoints included visual, anatomic, and quality-of-life NEI VFQ-25 outcomes at weeks 24 and 52.At week 24, 56.1% of IAI 2Q4 patients gained ≥15 letters from baseline compared with 12.3% of sham patients (P.001). At week 52, 55.3% of IAI 2Q4 + PRN patients gained ≥15 letters compared with 30.1% of sham + IAI PRN patients (P.001). At week 52, IAI 2Q4 + PRN patients gained a mean of 16.2 letters of vision vs 3.8 letters for sham + IAI PRN (P.001). The most common adverse events for both groups were conjunctival hemorrhage, eye pain, reduced visual acuity, and increased intraocular pressure.Monthly injections of 2 mg intravitreal aflibercept for patients with macular edema secondary to CRVO resulted in a statistically significant improvement in visual acuity at week 24, which was largely maintained through week 52 with intravitreal aflibercept PRN dosing. Intravitreal aflibercept injection was generally well tolerated.

To assess the efficacy and safety of intravitreal vascular endothelial growth factor (VEGF) Trap-Eye in eyes with macular edema secondary to central retinal vein occlusion (CRVO).Multicenter, randomized, prospective, controlled trial.One hundred eighty-nine eyes with macular edema secondary to CRVO.Eyes were randomized 3:2 to receive VEGF Trap-Eye 2 mg or sham injection monthly for 6 months.The proportion of eyes with a ≥15-letter gain or more in best-corrected visual acuity (BCVA) at week 24 (primary efficacy end point), mean changes in BCVA and central retinal thickness (CRT), and proportion of eyes progressing to neovascularization of the anterior segment, optic disc, or elsewhere in the retina.At week 24, 56.1% of VEGF Trap-Eye treated eyes gained 15 letters or more from baseline versus 12.3% of sham-treated eyes (P0.001). The VEGF Trap-Eye treated eyes gained a mean of 17.3 letters versus sham-treated eyes, which lost 4.0 letters (P0.001). Central retinal thickness decreased by 457.2 μm in eyes treated with VEGF Trap-Eye versus 144.8 μm in sham-treated eyes (P0.001), and progression to any neovascularization occurred in 0 and 5 (6.8%) of eyes treated with VEGF Trap-Eye and sham-treated eyes, respectively (P = 0.006). Conjunctival hemorrhage, reduced visual acuity, and eye pain were the most common adverse events (AEs). Serious ocular AEs were reported by 3.5% of VEGF Trap-Eye patients and 13.5% of sham patients. Incidences of nonocular serious AEs generally were well balanced between both groups.At 24 weeks, monthly intravitreal injection of VEGF Trap-Eye 2 mg in eyes with macular edema resulting from CRVO improved visual acuity and CRT, eliminated progression resulting from neovascularization, and was associated with a low rate of ocular AEs related to treatment.

To compare baseline characteristics, treatment frequency, visual acuity (VA), and morphologic outcomes of eyes with50% of the lesion composed of blood (B50 group) versus all other eyes (Other group) enrolled in the Comparison of Age-Related Macular Degeneration Treatments Trials (CATT).Prospective cohort study within a multicenter randomized clinical trial.CATT patients with neovascular age-related macular degeneration (AMD).Treatment for the study eye was assigned randomly to either ranibizumab or bevacizumab and to 3 different dosing regimens over a 2-year period. Reading center graders evaluated baseline and follow-up morphology in color fundus photographs, fluorescein angiography (FA), and optical coherence tomography (OCT). Masked examiners tested VA.Morphologic features and VA at 1 and 2 years.The B50 group consisted of 84 of 1185 (7.1%) patients enrolled in CATT. Baseline lesion characteristics differed between groups. In the B50 group, choroidal neovascularization size was smaller (0.73 vs 1.83 disc areas [DA]; P0.001), total lesion size was greater (4.55 vs 2.31 DA; P0.001), total retinal thickness was greater (524 vs 455 μm; P = 0.02), and mean VA was worse (56.0 vs 60.9 letters; P = 0.002). Increases in mean VA were similar in the B50 and Other groups at 1 year (+9.3 vs +7.2 letters; P = 0.22) and at 2 years (9.0 vs 6.1 letters; P = 0.17). Eyes treated PRN received a similar number of injections in the 2 groups (12.2 vs 13.4; P = 0.27). Mean lesion size in the B50 group decreased by 1.2 DA at both 1 and 2 years (primarily owing to resolution of hemorrhage) and increased in the Other group by 0.33 DA at 1 year and 0.91 DA at 2 years (P 0.001). Leakage on FA and fluid on OCT were similar between groups at 1 and 2 years.In CATT, the B50 group had a visual prognosis similar to the Other group. Lesion size decreased markedly through 2 years. Eyes like those enrolled in CATT with neovascular AMD lesions composed of50% blood can be managed similarly to those with less or no blood.

Children born prematurely who develop retinopathy of prematurity (ROP) often develop myopia, and those who require laser treatment may develop very high myopia, which has considerable clinical consequences.To report refractive outcomes in preterm infants who developed ROP in zone I or zone II posterior as stage 3+ ROP or aggressive posterior ROP (APROP).All infants received intravitreal bevacizumab or laser therapy in a prospective, stratified, randomized, controlled, masked, multicenter clinical trial, Bevacizumab Eliminates the Angiogenic Threat for ROP (BEAT-ROP). Children who received intravitreal bevacizumab or laser in the BEAT-ROP clinical trial, with treatment randomized by infant, underwent cycloplegic retinoscopic refraction at a mean age of 2½ years. Fifteen centers with both pediatric and vitreoretinal ophthalmologists participating in level 3 neonatal intensive care units in academic centers with institutional review board approval were included in the trial. Of the originally enrolled 150 infants (300 eyes) in the BEAT-ROP clinical trial, 13 infants (26 eyes) died (6 received intravitreal bevacizumab; 7 received laser) and 19 eyes had intraocular surgery (6 infants bilaterally). Thus, 45 eyes (19 infants bilaterally) were excluded, leaving 131 infants (255 eyes, including 21 eyes that received a successful second treatment for recurrence).Follow-up of the BEAT-ROP cohort.Spherical equivalent refractive outcomes and their distribution by ROP zone and treatment.Refractions were available for 109 of 131 eligible infants (83.2%) and 211 of 255 eyes (82.7%). Mean (SD) spherical equivalent refractions were as follows: zone I, -1.51 (3.42) diopters (D) in 52 eyes that received intravitreal bevacizumab and -8.44 (7.57) D in 35 eyes that received laser treatment (P .001); and zone II posterior, -0.58 (2.53) D in 58 eyes that received intravitreal bevacizumab and -5.83 (5.87) D in 66 eyes that received laser treatment (P .001). Very high myopia (≥-8.00 D) occurred in zone I in 2 of 52 (3.8%) eyes that received intravitreal bevacizumab and in 18 of 35 (51.4%) eyes that received laser treatment (P .001). Very high myopia occurred in zone II posterior in 1 of 58 (1.7%) eyes that received intravitreal bevacizumab and in 24 of 66 (36.4%) eyes that received laser treatment (P .001).More very high myopia was found in eyes that received laser treatment than in eyes that received intravitreal bevacizumab. This difference is possibly related to anterior segment development that is present with intravitreal bevacizumab but minimal or absent following laser treatment.clinicaltrials.gov Identifier: NCT00622726.

Purpose To evaluate the efficacy and safety of intravitreal aflibercept injection (IAI) for the treatment of macular edema secondary to central retinal vein occlusion (CRVO). Design Randomized, double-masked, phase 3 trial. Participants A total of 188 patients with macular edema secondary to CRVO. Methods Patients received IAI 2 mg (IAI 2Q4) (n = 114) or sham injections (n = 74) every 4 weeks up to week 24. During weeks 24 to 52, patients from both arms were evaluated monthly and received IAI as needed, or pro re nata (PRN) (IAI 2Q4 + PRN and sham + IAI PRN). During weeks 52 to 100, patients were evaluated at least quarterly and received IAI PRN. Main Outcome Measures The primary efficacy end point was the proportion of patients who gained ≥15 letters in best-corrected visual acuity (BCVA) from baseline to week 24. This study reports week 100 results. Results The proportion of patients gaining ≥15 letters was 56.1% versus 12.3% ( P P P P P P P P = 0.546), and 390.0 versus 343.3 μm at week 100 ( P = 0.366) in the IAI 2Q4 + PRN and sham + IAI PRN groups, respectively. The mean number (standard deviation) of PRN injections in the IAI 2Q4 + PRN and sham + IAI PRN groups was 2.7±1.7 versus 3.9±2.0 during weeks 24 to 52 and 3.3±2.1 versus 2.9±2.0 during weeks 52 to 100, respectively. The most frequent ocular serious adverse event from baseline to week 100 was vitreous hemorrhage (0.9% vs. 6.8% in the IAI 2Q4 + PRN and sham + IAI PRN groups, respectively). Conclusions The visual and anatomic improvements after fixed dosing through week 24 and PRN dosing with monthly monitoring from weeks 24 to 52 were diminished after continued PRN dosing, with a reduced monitoring frequency from weeks 52 to 100.

We report a case of posttransplantation lymphoproliferative disorder manifesting as an isolated, unilateral iris tumor. A 2-year-old boy who had undergone liver transplantation for biliary atresia at age 4 months was seen with a 2-month history of an enlarging iris nodule. Histopathologic examination of the iris lesion demonstrated a mixed population of lymphoid cells. To our knowledge, this is the youngest patient with posttransplantation lymphoproliferative disorder isolated to the eye.

Using polymerase chain reaction, we have isolated and sequenced a 3-kb cDNA for lysyl hydroxylase (LH) from human skin fibroblasts from an normal donor. Apart from two polymorphic sites, no differences were observed between the 2184 nt coding regions of LH cDNA from fibroblasts and placenta. However, four differences were observed in the 3' non-coding regions of the two cDNAs; three were single base changes and the fourth a deletion of a single base. The absence of the single nucleotide in the LH cDNA from fibroblasts resulted in the loss of an HpaII site that is present in the placental LH cDNA; this was confirmed in HpaII digests of fibroblast and placental LH cDNAs from the same donor. Northern blots showed that the LH gene was strongly expressed in fibroblasts and placenta and, to a lesser extent, in aorta, lung, vein, cartilage, and artery.
