To describe herpetic ocular infections following SARS-CoV-2 vaccinations.A retrospective study of herpetic ocular infections after BNT162b2mRNA vaccination and a literature review.A cohort of five patients: three varicella zoster virus (VZV) and two herpes simplex virus (HSV) cases, as well as 19 literature cases: 9 cases of VZV and 10 cases of HSV post BNT162b2mRNA, AZD1222, mRNA-1273, and CoronaVac vaccinations. All cases presented within 28 days post vaccination. Most VZV and HSV cases (15/19) reported in the literature presented post first vaccine dose, while in our cohort 2 VZV cases presented post second dose and both HSV cases and one VZV case post third dose. The most common presentations were HZO with ocular involvement and HSV keratitis. All eyes had complete resolution; however, one had retinal detachment and three corneal scars.Herpetic ocular infections may develop shortly after SARS-CoV-2 vaccinations. Overall, the outcome is good.

Background/AimsThe SARS-CoV-2 pandemic has imposed barriers to retinal care delivery worldwide. In this context, retinal services are exploring novel ways to ensure access to healthcare.MethodsWe conducted a worldwide survey among retinal specialists between March 31, 2020 and April 12, 2020. The expert survey was developed on the basis of focus group discussions involving retinal specialists and literature searches. It included 44 questions on alternative ways of care provision including digital health domains such as teleophthalmology, home monitoring or decentralised patient care.Results214 retinal experts participated in the survey, of which 120 (56.1%) had more than 15 years of experience in ophthalmology. Most participants were clinicians (n=158, 73.9%) practising in Western Europe (n=159, 74%). In the majority of institutions, teleophthalmology, home monitoring and decentralised patient care have not been implemented before the pandemic (n=46, 21.8.1%; n=64, 29.9%; n=38, 19.1%). During the pandemic, the use of teleophthalmology and home monitoring increased significantly (n=105, pConclusionDigital health is taking the centre stage tackling unpreceded challenges of retinal care delivery during the SARS-CoV-2 pandemic and may sustainably change the way we practice ophthalmology.

Purpose: To analyze the correlation between age, gender, refractive error, keratometry, and corneal thickness in a large group of subjects. Methods: This study is a retrospective analysis of patients who underwent refractive surgery between January 2000 and February 2015 at Care Vision Refractive Clinic, Tel Aviv, Israel. Patient demographics, subjective refraction, pachymetry, and average keratometry were collected. Results: Overall, 51,113 eyes of patients averaging 28.8 ± 9.3 years of which 53.9% were males were included. Average keratometry, spherical equivalent and cylindrical error differed significantly between male and female subjects (p Conclusion: Refractive state, pachymetry, and keratometry of refractive surgery candidates are mostly weakly correlated.

Purpose To evaluate the surgical outcomes of traditional scleral buckling (TSB) compared to chandelier-assisted scleral buckling (CSB) for rhegmatogenous retinal detachment repair. Patients and methods A retrospective interventional comparative case series of 49 eyes that underwent SB procedure. Medical records of 27 and 22 eyes that underwent TSB and CSB surgery, respectively, were evaluated. Outcome measures included primary anatomical success, visual acuity (VA), and perioperative complications. Results Primary reattachment rate was similar with 85.2% in the TCB group and 81.8% in the CSB group (P=1.00); eight patients needed one additional operation or gas injection with a final reattachment rate of 100% at 6 months. Mean VA in the CSB group improved from 20/60 at presentation to 20/35, 6 months postoperatively. In the TSB group, VA improved from 20/80 to 20/45 (P=0.90). Among the eyes that were successfully reattached with either SB approach, two eyes in each group had cataract progression and none of them required surgery during follow-up. No cases of endophthalmitis were observed. Conclusion CSB is a modified technique with an advantage of superior visualization compared with the traditional surgery, which simplifies the operation, enhance competency, and could be used as a valuable educational tool. It can provide similar anatomical and functional outcomes with no additional perioperative complications.

OBJECTIVES This paper evaluates the accuracy of the Eye-N-JOY (ENJ), a novel device (Patent no. US 9844317 B2), for identifying the presence of amblyopic risk factors. This device was developed to assess both visual acuity, ocular alignment, and eye movement; all while watching images on a tablet screen. METHODS A prospective, single-center, comparison study. Participants were examined by the ENJ first and then underwent a comprehensive full eye examination by pediatric ophthalmologists including cycloplegic refraction. Both the technician operating the ENJ and the physicians were masked to each other's findings. Children aged 18-72 months (1.5 to 6 years) attending a tertiary medical center for a full standard pediatric ophthalmology examination were included. The visual acuity and alignment were compared between the ENJ and the gold standard full ophthalmologic examination. The differences were noted, and the sensitivity and specificity were calculated. RESULTS A total of 51 children were enrolled, 33 (64.7%) girls, aged 18-72 months. All children successfully completed the examination by the ENJ. No significant difference between the ENJ and the reference examination was detected in visual acuity measurements in both eyes (Pv = 0.553 for the right eye and 0.803 for the left). Overall agreement between all referral indications between the ENJ and reference examination was 84.3%, with 90.9% agreement in VA referral criteria and 90.1% in alignment referral criteria. CONCLUSIONS Eye-N-Joy can reliably examine both visual acuity and ocular misalignment in verbal and pre-verbal children.

Studies of energy flow in quantum systems complement the information provided by common conductance measurements. The quantum limit of heat flow in one-dimensional ballistic modes was predicted, and experimentally demonstrated, to have a universal value for bosons, fermions, and fractionally charged anyons. A fraction of this value is expected in non-Abelian states; harboring counterpropagating edge modes. In such exotic states, thermal-energy relaxation along the edge is expected, and can shed light on their topological nature. Here, we introduce a novel experimental setup that enables a direct observation of thermal-energy relaxation in chiral 1D edge modes in the quantum Hall effect. Edge modes, emanating from a heated reservoir, are partitioned by a quantum point contact (QPC) constriction, which is located at some distance along their path. The resulting low frequency noise, measured downstream, allows determination of the "effective temperature" of the edge mode at the location of the QPC. An expected, prominent energy relaxation was found in hole-conjugate states. However, relaxation was also observed in particlelike states, where heat is expected to be conserved. We developed a model, consisting of distance-dependent energy loss, which agrees with the observations; however, we cannot exclude energy redistribution mechanisms, which are not accompanied with energy loss.

Background Optic nerve head drusen (ONHD) are considered the most common cause for pseudopapilloedema in children. We aimed to investigate and further characterize a new type of optic nerve head lesion on enhanced depth imaging optical coherence tomography (EDI-OCT) named peripapillary hyperreflective ovoid mass-like structures (PHOMS), and ONHD in asymptomatic children with pseudopapilloedema. Methods Retrospective cohort study including 64 eyes from 32 patients with pseudopapilloedema due to PHOMS and/or ONHD. Mean age was 9.0 ± 3.1 years. PHOMS and ONHD were identified and classified on EDI-OCT and infrared images. Ultrasound images were classified for the presence of hyperechogenic structures of the optic nerve head. Results On EDI-OCT, PHOMS were detected in 63 out of 64 eyes (98.4%). In 60 eyes (93.8%), small hyperreflective foci inside the PHOMS were present. In all cases, we identified a new ring sign visible on infrared images, corresponding clearly to the edge of the PHOMS as seen on EDI-OCT. On ultrasound, we describe a new feature of PHOMS appearing as small hyperechogenic structures without posterior shadowing. In 13 eyes (20.3%), ONHD were present on EDI-OCT and ultrasound. Conclusion This is the first study showing that PHOMS are the most common cause for pseudopapilloedema in children. PHOMS is a new entity of optic nerve head lesions. It might be a precursor of buried optic nerve head drusen, which can lead to visual field defects, haemorrhages and CNV. This study offers new tools to identify and follow-up these lesions early in childhood using EDI-OCT.

Background High and increasing drug prices have prompted the establishment of a broad range of cost-containment treatment policies in health systems globally. In 2012, the supplemental insurance program of a large Israeli health maintenance organization (Clalit Health Services) introduced a prior authorization process for second-line use of ranibizumab in patients with retinal disease for whom treatment with bevacizumab proved to be ineffective. A Clalit steering committee established authorization criteria based on cost and periodically updated clinical considerations, while a team of ophthalmic specialists evaluated their colleagues’ individual patient subsidization requests, based on the funding criteria. The objectives of this study were to detail this unique authorization process and study its effectiveness in limiting unwarranted spending, while allowing for a smooth transition to a second-line more expensive drug when needed. Methods A retrospective cohort study including all applications for a first or ongoing treatment with ranibizumab, for one or both eyes, received during March 1, 2012 - December 31, 2015. The key parameters examined were percentages of requests from patients treated by first line treatment bevacizumab, requests approved, reapplications, and results. Requests studied include reapplications and requests for treatment continuation. Results During the study period, Clalit affiliated ophthalmologists’ submitted 16,778 funding applications for intravitreal ranibizumab treatment on behalf of 5642 patients who applied for approximately three applications. An efficient sentinel effect was achieved, resulting in only 31% of patients treated with bevacizumab applying for treatment, while maintaining extremely high accessibility to second line treatment with almost 95% of requests being approved. Conclusions The data presented shows a low request rate for funding with a high approval rate, proving this peer reviewed report-based authorization process successfully achieved a sentinel effect while controlling cost. We suggest this innovative model be considered in similar decisions processes.

Purpose To evaluate the efficacy, effect profile, and safety of dexamethasone implant on diabetic macular edema (DME) in a real-life setting, further comparing results by DME duration, previous treatment status, and diabetic control. Design A multicenter, retrospective cohort of 340 DME eyes of 287 patients from 25 clinical sites from 8 countries. Methods Data were analyzed in 2 perspectives: per injection, in which all measurements were grouped and baseline was defined as the day of injection, and thus the pharmacodynamics of single injections could be assessed; and injection series, defined as 2 or more injections with 3 to 6 months between injections analyzing the outcome 3 to 6 months after the last injection. Main Outcome Measures Primary outcome was improvement of 15 or more letters in best-corrected visual acuity (BCVA) from baseline. Secondary outcomes included improvement of 10 letters or more in BCVA, change in central macular thickness (CMT), and time to maximum improvement and safety. Results Overall, 762 injections were administered to 340 eyes of 287 patients. Injection series analysis included 171 series in 171 eyes of 150 patients, for a total of 444 injections, with a mean follow-up of 1.7±0.8 years. Of the 762 injections analyzed per injection, 22.7% achieved a 15-letter or more improvement, and 37.8% achieved a 10-letter or more improvement. Mean time to peak improvement was 81.9±39.7 days. Mean maximum change in CMT was –174±171 μm. Overall, 7.6% lost 15 or more letters. More eyes with early DME gained 10 or more letters and fewer eyes lost 10 or more letters compared with eyes with late DME (47.4% vs. 33.9% [P = 0.001] and 8.2% vs. 13.5% [P = 0.029], respectively). Patients with controlled diabetes showed greater CMT reduction (P = 0.0002). A higher percentage of treatment-naive patients gained 10 or 15 letter or more in BCVA (P = 0.001 and P = 0.006, respectively). Intraocular pressure elevation of more than 25 mmHg was found following 7.9% of injections; no endophthalmitis was reported. Conclusions Dexamethasone implant is an effective and safe treatment for DME. Peak improvement was achieved 3 months after injection and dissipated thereafter. Clinicians and providers may consider shortening treatment intervals.

To describe the demographics and clinical characteristics of patients with herpetic anterior uveitis (HAU), and compare characteristics by pathogen, recurrence, and association to iris atrophy.Multicenter, retrospective study of AU patients diagnosed clinically and by polymerase chain reaction (PCR).The study included 112 eyes in 109 patients: 54 (48.2%) HSV, 34 (30.4%) VZV, 2 (1.8%) CMV, and 22 (19.6%) unspecified diagnosis. HSV eyes, compared to VZV, had a higher recurrence rate, corneal involvement, KPs, iris atrophy, elevated IOP and posterior synechia (p 0.05). VZV patients had more frequent immunomodulatory treatments and history of systemic herpetic disease (p 0.05). Fifty-nine (52.7%) eyes had recurrent disease. Iris atrophy was associated with a higher prevalence of posterior synechia, dilated distorted pupil, and high IOP (p 0.05).Different HAU-causing Herpesviridae produce common clinical findings; therefore, PCR should be used more often to confirm specific diagnosis. Iris atrophy was associated with more severe disease.

Purpose To analyze the outcomes of Descemet membrane endothelial keratoplasty (DMEK) in eyes with previous Descemet stripping automated endothelial keratoplasty (DSAEK). Methods This retrospective interventional case series included 26 eyes (26 patients) that underwent DMEK to replace a previous DSAEK graft with at least 6 months of follow-up. The outcome measures were indications for surgery, best spectacle-corrected visual acuity (BSCVA), endothelial cell density, rebubbling rate, rejection, and failure. Results Patient age was 71.9 ± 12.6 years. The average follow-up time after DMEK was 15.1 ± 10.6 months. Indications for DMEK were DSAEK graft failure (69%) and a DSAEK suboptimal visual outcome (31%). BSCVA of the entire cohort (n = 26) improved from 1.33 ± 0.78 logMAR preoperatively to 1.04 ± 0.78 and 1.06 ± 0.89 logMAR at 6 months postoperatively and at the last follow-up, respectively (P = 0.019 and P = 0.033). BSCVA among eyes without visual comorbidities (n = 13) improved from 0.84 ± 0.50 logMAR preoperatively to 0.55 ± 0.47 and 0.51 ± 0.49 logMAR at 6 months postoperatively and at final follow-up, respectively (P = 0.023 for both). Of these eyes, 84.6% had improvement in BSCVA at 6 months postoperatively and at last follow-up. In the subgroup of 8 eyes with DMEK for suboptimal visual outcomes after DSAEK, BSCVA improved from 0.81 ± 0.44 to 0.52 ± 0.35 logMAR at final follow-up (P = 0.024). When excluding eyes with visual comorbidities, BSCVA of this subgroup (n = 5) improved from 0.54 ± 0.32 to 0.36 ± 0.25 logMAR at final follow-up (P = 0.038). BSCVA of this subgroup at 6 months postoperatively was not significantly different from preoperative BSCVA, when including visual comorbidities (n = 8, 0.75 ± 0.60 logMAR, P = 0.79) and when excluding visual comorbidities (n = 5, 0.40 ± 0.28 logMAR, P = 0.621). Endothelial cell density decreased from 2753 ± 307 cells/mm to 1659 ± 655 cells/mm 6 months after surgery (39.7% loss, P = 0.005). Three eyes (11.5%) required rebubbling, and 5 eyes (19.2%) had secondary graft failure at 2 to 20 months. Conclusions DMEK is effective for replacing previous DSAEK not only for graft failure but also for suboptimal visual outcomes.

To determine whether early visual acuity response to intravitreal dexamethasone implant therapy in diabetic macular edema (DME) is associated with long-term outcome.Retrospective case series.Multicenter (8 sites) retrospective review of medical records of eyes with DME treated with 0.7 mg intravitreal dexamethasone implant and minimum 18-month follow-up. One hundred and two eyes were included. Eyes with vitreoretinal interface abnormalities or that had undergone vitrectomy were excluded. Eyes were categorized into 3 groups based on change in best-corrected visual acuity (BCVA) at 3 months (logMAR equivalence of5-letter, 5-9-letter, or ≥10-letter gain). Visual acuity outcomes were determined for each early response group. The relationship between early (3-month) and overall change in BCVA was assessed using regression analysis.In the study population (102 eyes),5-letter, 5- to 9-letter, and ≥10-letter BCVA improvements were seen in 44.1%, 18.6%, and 37.3% of eyes, respectively, at 3 months. Among suboptimal (5-letter) responders at 3 months, 6.7% showed ≥10-letter gains at study conclusion compared to 29% in the robust (≥10-letter) early response group (P = .009). Change in BCVA at 3 months showed significant positive correlation with overall change in BCVA (coefficient = 0.44, P = .002).A similar proportion of eyes demonstrated suboptimal (5-letter) and robust (≥10-letter) early response to treatment at 3 months. Eyes with a robust early response demonstrated ≥10-letter long-term gain in BCVA at a significantly higher rate compared to those with poor early response. Early treatment response directly correlated with overall change in BCVA.

Purpose To describe a modified technique for Descemet membrane donor tissue preparation that facilitates the original Melles stripping technique. Methods Descemet membrane is prepared using a Rootman/Goldich modified Sloane microhoe, using a blunt instrument as opposed to a sharp blade or needle and begins dissection within the trabecular meshwork. The trabecular tissue is dissected for 360 degrees, and then Descemet membrane is stripped to approximately 50%. A skin biopsy punch is then used to create fenestration in the cornea, which is used to mark an "F." on the stromal side of Descemet membrane to aid in orientation of the graft. Trephination of the membrane is then performed and stripping is completed. The tissue is stained with 0.06% trypan blue and aspirated into an injector for insertion into the anterior chamber. Results Before converting to the technique described, 5 of 75 (6.7%) tissues were wasted and 7 of 75 (9.3%) tissues with radial tears were salvaged for use. Since converting to the new technique, only 1 of 171 (0.6%) (P = 0.01) tissues was wasted and 7 of 171 (4.1%) (P = 0.2) tissues with radial tears were salvaged. Conclusions The peripheral blunt dissection technique offers an improvement over the technique originally described by Melles et al, as the incidence of tissue wastage and tears is lower, it is easy to learn, has low stress, and is reproducible. Combining this with a stromal surface letter mark ensures correct orientation of the tissue against the corneal stroma of the recipient.

The nature of edge reconstruction in the quantum Hall effect (QHE) and the issue of where the current flows have been debated for years. Moreover, the recent observation of proliferation of ‘upstream’ neutral modes in the fractional QHE has raised doubts about the present models of edge channels. Here, we present a new picture of the edge reconstruction in two of the hole-conjugate states. For example, while the present model for ν = (2/3) consists of a single downstream chiral charge channel with conductance (2/3)(e2/h) and an upstream neutral mode, we show that the current is carried by two separate downstream chiral edge channels, each with conductance (1/3)(e2/h). We uncover a novel mechanism of fragmentation of upstream neutral modes into downstream propagating charge modes that induces current fluctuations with zero net current. Our unexpected results underline the need for better understanding of edge reconstruction and energy transport in all fractional QHE states. Two challenging questions related to the quantum Hall effect (QHE) are how edge reconstruction works and where the current flows. A new model now gives the answer for two types of QHE states — two separate downstream chiral edge channels are involved.

Purpose:To evaluate the effect of intracameral Bevacizumab on trabeculectomy success rates.Methods:A prospective, randomized, interventional clinical trial. Patients with primary open-angle glaucoma were randomly assigned to two groups: trabeculectomy with mitomycin C and trabeculectomy with mitomycin C and intracameral bevacizumab. Complete success is defined as an intraocular pressure (IOP) reduction of at least 30% from baseline IOP to a measured pressure of between 5 and 18 mm Hg without the use of IOP lowering medications. Qualified success is defined as same achievement of reduced IOP, but with the use of IOP lowering medications. Overall success is defined as same achievement of reduced IOP with or without the use of IOP lowering medications.Results:Thirty-three patients in the mitomycin C group and 36 patients in the mitomycin C and bevacizumab group were included in final analyses. The IOP at presentation was 28.3 ± 8 and 28.4 ± 8.6 mm Hg, compared to 10.8 ± 3.4 and 12.3 ± 3.7 mm Hg at 12 months (p Conclusion:Intracameral bevacizumab during mitomycin C trabeculectomy in patients with primary open-angle glaucoma apparently does not improve success rates. The adjuvant use of intracameral bevacizumab is therefore not justified.

Purpose: To investigate the accuracy of high frequency ultrasound biomicroscopy using the bag/balloon technique to locate recti muscle insertions before and after strabismus surgery. Methods: This was a prospective masked study. The distance from the limbus to horizontal recti muscle insertions was measured by caliper intraoperatively and ultrasound biomicroscopy preoperatively and during follow-up. Accuracy was defined as the difference between ultrasound biomicroscopy and caliper measurements. Results: Thirty-nine muscles (19 medial rectus and 20 lateral rectus) of 22 patients were included. The mean age of the patients was 34.7 ± 15.5 years (range: 18 to 78 years). Follow-up measurements were available for 25 muscles: 12 muscles were recessed and 13 were resected/advanced. Twelve of the included muscles underwent prior surgery. There was a strong correlation between preoperative mean ultrasound biomicroscopy and caliper measurements ( P < .001, r p = 0.872) without significant difference between the accuracy of identification of medial rectus and lateral rectus muscles ( P = .116 and .377, respectively). On average, postoperative ultrasound biomicroscopy measurements of recessed muscles were 1.15 mm greater than caliper measurements at the end of surgery ( P = .003), whereas the mean difference in the resected muscles was not statistically significant (−0.07 mm, P > .999). Overall, in 16 of 25 muscles (64%), the differences between the postoperative measurements and the end of surgery measurements were less than 1 mm. There was no correlation between the accuracy and the time of ultrasound biomicroscopy after surgery ( P = .516). Conclusions: The ultrasound biomicroscopy bag/balloon technique is an accurate and reliable method of locating recti muscle insertions before and after strabismus surgery. Ultrasound biomicroscopy may assist strabismologists in planning repeated operations. [ J Pediatr Ophthalmol Strabismus. 2020;57(1):12–20.]

Purpose To evaluate the surgical outcomes of traditional scleral buckling (TSB) compared to chandelier-assisted scleral buckling (CSB) for rhegmatogenous retinal detachment repair. Patients and methods A retrospective interventional comparative case series of 49 eyes that underwent SB procedure. Medical records of 27 and 22 eyes that underwent TSB and CSB surgery, respectively, were evaluated. Outcome measures included primary anatomical success, visual acuity (VA), and perioperative complications. Results Primary reattachment rate was similar with 85.2% in the TCB group and 81.8% in the CSB group (P=1.00); eight patients needed one additional operation or gas injection with a final reattachment rate of 100% at 6 months. Mean VA in the CSB group improved from 20/60 at presentation to 20/35, 6 months postoperatively. In the TSB group, VA improved from 20/80 to 20/45 (P=0.90). Among the eyes that were successfully reattached with either SB approach, two eyes in each group had cataract progression and none of them required surgery during follow-up. No cases of endophthalmitis were observed. Conclusion CSB is a modified technique with an advantage of superior visualization compared with the traditional surgery, which simplifies the operation, enhance competency, and could be used as a valuable educational tool. It can provide similar anatomical and functional outcomes with no additional perioperative complications.

Previous studies demonstrated the potential pathogenic relationship between infestation of the eyelashes by the parasite Demodex and chronic blepharitis, whereas other studies did not demonstrate such relations and concluded that Demodex is a normal eyelid flora.This study examines the prevalence of Demodex in patients with blepharitis compared to a healthy control group in Israel, in order to further explore and establish its pathogenic role in cases of chronic blepharitis.A case-control study was conducted including 110 participants: 60 patients with chronic blepharitis attending a tertiary medical center and 50 subjects with no signs of blepharitis. Six to eight eyelashes were epilated from each participant and studied microscopically for the presence of Demodex by a blinded examiner. Fluorescein stain was added to the "clean" samples in order to reduce the false negative results.Demodex were identified on the eyelashes of 44 patients with blepharitis (73.3%) and 20 controls (40%) (p0.001). After adjusting for age, blepharitis was still a significant risk factor for the presence of Demodex (OR=2.96, CI 95% 1.2-7.3).This study supports previous studies demonstrating pathogenic relationship between Demodex infestation of the eyelashes to chronic blepharitis. The authors recommend epilating 6-8 lashes of patients with blepharitis for microscopic identification of these parasites. Fluorescein stain may have a limited role in the recognition of Demodex in parasite free samples.

Objective. To analyze the safety and efficacy of high-myopic PRK as an alternative to LASIK surgery in patients with a high preoperative percentage tissue altered (PTA).Design. Retrospective interventional case series.Participants.Charts of 256 consecutive eyes that underwent PRK with application of mitomycin-C 0.02% for high myopia were retrospectively reviewed.Methods. Refractive (refraction and refractive accuracy) and visual outcomes (uncorrected and corrected visual acuities), as well as occurrence of haze in the eyes with preoperative PTA expected to be higher than 40% with a 110-micron flap if undergoing LASIK surgery, were analyzed.Results. Mean follow-up was 7.3 ± 4.8 months. A total of 187 of 256 eyes (73.0%) were included in the analysis because they were expected to have a PTA greater than 40%, should they have undergone LASIK surgery. The actual mean PTA of those eyes following PRK was 31.8 ± 2.2%, and none had a PTA ≥ 40%. UDVA of 20/16, 20/20, and 20/25 or better was achieved in 1.2% (2 eyes), 65.5% (112 eyes), and 85.4% (146 eyes), respectively. The percentage of eyes with postoperative SE within ±0.5 D and ±1.0 D of planned SE was 71% and 93%, respectively. None of the eyes lost 2 or more lines of CDVA. The rate of stromal haze, managed successfully with topical steroids only, was 4.8%.Conclusion. High-myopic PRK with application of mitomycin-C in the eyes at risk of developing ectasia because of high preoperative PTA was demonstrated to be a safe and effective alternative to the LASIK procedure.

BACKGROUND/OBJECTIVES To investigate if the visual and anatomic response to the first dexamethasone implant (DEX) predicts the 12-month clinical outcome after shifting to fluocinolone acetonide (FAc) implant in patients with diabetic macular oedema (DMO). METHODS Retrospective cohort study including pseudophakic patients with previously treated DMO, undergone one or more DEX injections before FAc. Functional and morphologic response to DEX was defined based on the best-corrected visual acuity (BCVA) and central macular thickness (CMT) changes after the first DEX, respectively. Steroid-response was defined as intraocular pressure (IOP) elevation ≥5 mmHg or IOP > 21 mmHg after any previous DEX exposure. Pairwise comparisons for BCVA, CMT, and IOP after FAc were performed with linear mixed models and a repeated-measure design. RESULTS Forty-four eyes of 33 patients were included. Patients were shifted to FAc after a mean ± standard deviation of 4.6 ± 3.2 DEX injections. Overall, BCVA and CMT improved during the first 12 months after switching to FAc (p = 0.04 and p

Purpose To examine the efficacy of corneal collagen cross-linking (CXL) for the treatment of keratoconus (KCN). Methods A systemic literature review and meta-analysis of ocular functional and structural parameters of patients with KCN undergoing cross-linking procedures were performed using PubMed and the web of science. A literature search was performed for relevant peer-reviewed publications on population-based studies. Data were analyzed with R software (Meta library), and heterogeneity was assessed with the Cochran Q and I. A random-effects model was used for high heterogeneity; otherwise a fixed model was used. Sensitivity analysis of particular tested groups was used to explain high heterogeneity. The main outcome measures extracted from the articles were corrected distance visual acuity, uncorrected distance visual acuity, and maximum K. Results An improvement in visual acuity of 1 to 2 Snellen lines was found 3 months or more after undergoing CXL. Changes were more pronounced in uncorrected visual acuity. Some topography parameters were found to be improved (0.6-1 diopters) 12 to 24 months after CXL. The refractive cylinder improved by 0.4 to 0.7 diopters. Endothelial cell density decreased by 225 cells per square millimeter in the first 3 months and thereafter returned to normal. Corneal thickness was reduced by 10 to 20 μm in the year following CXL but not after 24 months. No changes in intraocular pressure were noted. Conclusions CXL is a safe and effective method for halting the deterioration of KCN, while slightly improving visual function.

To investigate the characteristics and long-term outcome of patients with noninfectious retinal vasculitis.This was a retrospective multicenter study. Main outcome measures included patients' characteristics, ocular findings, treatment modalities, and best-corrected visual acuity. All patients had at least 12-month follow-up time.Eighty-two eyes (45 patients) were included. Median follow-up was 46 months (range, 12-210 months). At presentation, 12 of the 45 patients (26.6%) had a known associated systemic or ocular disease. A diagnosis of a new systemic disease was found in additional 14 of 33 patients (42.5%) and birdshot chorioretinopathy in 3 of 33 patients (9.1%). The most common systemic disease was Behcet disease (17/24 patients; 70.8%). Laboratory tests had a low diagnostic value. The most common clinical findings were vitritis (58.5%) and perivascular sheathing (50.5%). Most patients were treated with immunosuppressive medications. Mean best-corrected visual acuity improved significantly during follow-up, patients with Behcet disease and worse visual acuity at baseline were more likely to have visual acuity improvement (P0.001).A new systemic or ocular disease associated with retinal vasculitis was found in more than half of the patients. Behcet disease was the most common newly diagnosed disease. Specific diagnosis leading to proper management is important to maintain favorable long-term visual outcome.

A backward current Two-dimensional materials in a magnetic field can exhibit the so-called quantum Hall effect. This regime is characterized by currents running along the edge of the sample in the “downstream” direction determined by the sign of the magnetic field. Lafont et al. studied electrical transport in GaAs-AlGaAs heterostructures, focusing on a previously less-studied spin-unpolarized state in the fractional quantum Hall regime. By considering various experimental configurations, they observed a component of the charge current flowing in the opposite, “upstream” direction. Science , this issue p. 54

Purpose: The aim of this study was to evaluate pseudoexfoliation (PXF) as an independent risk factor for the occurrence of retinal vein occlusion (RVO). Methods: This is a retrospective cohort study on the records of 300 PXF glaucoma patients (PXF group), 300 non-PXF glaucoma patients, and 599 nonglaucoma non-PXF (nGnP group) patients. Results: Multivariate analysis resulted in a significant probability for RVO in the PXF (p = 0.005; OR 2.29 [1.13–4.68]) and non-PXF glaucoma groups (p = 0.005; OR 3.03 [1.55–5.94]) compared to the nGnP group. There was a much higher probability for central RVO (CRVO) in the PXF (p = 0.013; OR 3.64 [1.39–9.49]) and non-PXF glaucoma groups (p = 0.013; OR 3.78 [1.48–9.65]) compared to the nGnP group. After matching and excluding neovascular glaucoma, no significant difference was found between the PXF and non-PXF glaucoma groups regarding RVO (p = 0.541), CRVO (p = 0.092), and branch RVO (p = 0.774). Conclusions: PXF and other types of glaucoma are associated with RVOs, mainly CRVO. PXF was not found to be an independent risk factor for CRVO.

Background and aims: Primary sclerosing cholangitis (PSC) is a rare chronic progressive cholestatic disorder. We assessed its characteristics and natural history in Israel and compared its outcome with respect to coexisting inflammatory bowel disease (IBD). Methods: Data on characteristics, course and outcome were retrospectively retrieved on patients diagnosed with PSC from five large Israeli medical centers between 1988 and 2012. Patients with isolated PSC were compared with those with coexisting IBD to identify predictors of outcome. Results: Of 141 patients (56% males) with confirmed PSC, 98 (69.5%) had coexisting IBD. The average age at presentation was 38.8±15.4 years and duration of follow-up was 7.93±6.26 years. The crude estimated point prevalence was 4 cases per 105 persons. Demographics and clinical characteristics were similar among all patients except for symptoms at diagnosis (which were more prevalent among PSC–IBD patients) and utilization of multiple diagnostic modalities (which was more prevalent among isolated-PSC patients). More than one-third of the entire cohort had cirrhosis. A total of 15 patients (10.6%) died and 19 patients (13.5%) developed malignancy during follow-up. Nine patients (6.3%) underwent liver transplantation. Mean survival for the entire cohort was 26.3±1.4 years and mean transplant-free survival was 23.5±1.6 years. Cox proportional-hazard regression for transplantation or death revealed two independent risk factors: cirrhosis and malignancy [hazard ratio 4.25 ( p = 0.004) and 2.58 ( p = 0.046), respectively]. Conclusions: Survival rate of PSC patients in Israel is longer than reported rates worldwide and is independent of coexisting IBD. * Abbreviations: : PSC : primary sclerosing cholangitis; IBD : inflammatory bowel disease; CCA : cholangiocarcinoma; LT : liver transplantation; UC : ulcerative colitis; ERCP : endoscopic retrograde cholangiopancreatography; UDCA, ursodeoxycholic acid; MRCP : magnetic resonance cholangiopancreatography; CD : Crohn’s disease.

To report new cases of orbital inflammatory syndrome (OIS) post group A streptococcal (GAS) infection and review the literature.A retrospective case series of patients with OIS post GAS infection seen in our clinic (from January 2015 to December 2016) and review of additional patients from the literature.A total of nine patients with OIS post GAS infection were included in the study (four patients seen in our clinic and five from previous literature); seven females and two males, three children (under the age of 16), and six adults. Eight patients (89%) presented with a single rectus muscle (5 medial, 3 lateral) myositis, and one (11%) presented with posterior scleritis and diffuse OIS.Although there are very few reports on OIS post GAS infection, it may be more common than previously thought and should be considered in the differential diagnosis of patients with orbital inflammation.

Thyroid-associated ophthalmopathy (TAO) is an inflammatory disease that affects the thyroid gland and the eye orbit. Of patients with TAO, 3%-5% have severe sight-threatening disease due to optic neuropathy Optical coherence tomography (OCT), the non-invasive imaging technology that yields high-resolution cross-sectional images of the retina, provides qualitative and quantitative data on the retina.To apply this technique to quantitatively assess retinal nerve fiber layer (RNFL) and macular ring thicknesses in healthy subjects and in patients with TAO to determine their relationship to the severity of the orbital disease.All patients in the ophthalmology clinic who were diagnosed with TAO and underwent OCT imaging as part of their ocular examination comprised the study group, and healthy patients who volunteered to undergo OCT examination served as controls. Results of the complete ophthalmologic examination and OCT findings were collected from medical files, including the thickness of the RNFL and the macula.The study comprised 21 patients and 41 healthy controls. TAO patients exhibited RNFL thickening and inner macula thinning compared to healthy subjects. Mean RNFL thickness was correlated with the severity of the orbital disease.The OCT findings suggest that the retina is involved in TAO, probably as early as the subclinical stage. This highlights the ability of OCT to identify retinal changes earlier and far more accurately than is detected today, enabling earlier diagnosis and more timely treatment to prevent severe visual sequelae.

Several reports suggested a relation between uveitis and thyroid disease or dysfunction. However, no study has investigated the association between uveitis and thyroid dysfunction. The purpose of this study was to compare the prevalence of thyroid dysfunction in patients with and without non-infectious uveitis.This was a retrospective, case-control study.Two hundred thirty-five non-infectious uveitis patients (uveitis group) and 600 controls (control group) were included in the study, of whom 492 (58.9%) were females. No differences were demonstrated between the uveitis and control groups with regard to baseline characteristics, including age, sex, and the presence of systemic diseases such as diabetes, hypertension, and cardiac disease. Rheumatologic and gastrointestinal disease were more common in the uveitis group (p 0.001 and p = 0.007, respectively). Overall, thyroid dysfunction was noted in 61 (7.3%) patients, of whom 55 had hypothyroidism and six had hyperthyroidism. Seventeen out of 235 (7.2%) uveitis patients and 44/600 (7.3%) controls were diagnosed with thyroid dysfunction-a similar proportion in both groups (p = 0.96). Of these, all uveitis patients and 38 (86.4%) patients in the control group had a diagnosis of hypothyroidism (p = 0.63). A higher percentage of women was found among uveitis patients with thyroid dysfunction compared with uveitis patients without thyroid dysfunction (p = 0.002). The most common uveitis type was anterior uveitis. No significant difference was found in uveitis types between patients with or without a diagnosis of thyroid dysfunction.The prevalence of thyroid dysfunction was similar in both groups, and no association was found between non-infectious uveitis and thyroid dysfunction in this study. These findings suggest there is no need for routine thyroid function evaluation in patients with non-infectious uveitis.

Controlling the transmission of electrical current using a quantum point contact constriction paved a way to a large variety of experiments in mesoscopic physics. The increasing interest in heat transfer in such systems fosters questions about possible manipulations of quantum heat modes that do not carry net charge (neutral modes). Here we study the transmission of upstream neutral modes through a quantum point contact in fractional hole-conjugate quantum Hall states. Employing two different measurement techniques, we were able to render the relative spatial distribution of these chargeless modes with their charged counterparts. In these states, which were found to harbor more than one downstream charge mode, the upstream neutral modes are found to flow with the inner charge mode—as theoretically predicted. These results unveil a universal upstream heat current structure and open the path for more complex engineering of heat flows and cooling mechanisms in quantum nano-electronic devices., Understanding the transfer of heat currents, specifically, neutral heat modes which do not carry net charge, is of great interest. Here, the authors study the transmission of upstream neutral modes through a quantum point contact in order to render the relative spatial distribution of these chargeless modes.

PURPOSE The aim of this study was to assess the implications of a retained anterior chamber intraocular lens (ACIOL) during Descemet stripping automated endothelial keratoplasty (DSAEK) and to compare the outcomes in this group with those in patients who underwent DSAEK and had a posterior chamber intraocular lens (PCIOL). METHODS This is a retrospective cohort study conducted in a tertiary medical center, which compares patients who underwent DSAEK and had a retained ACIOL with patients who underwent DSAEK and had a PCIOL regarding operative and postoperative complications, visual acuity, endothelial cell density, and long-term graft survival. RESULTS Eleven eyes with an ACIOL and 50 eyes with a PCIOL met the study criteria. No significant differences were found between the groups in terms of operative complications, change in visual acuity, graft survival, and endothelial cell loss. CONCLUSIONS DSAEK in the setting of an ACIOL produced similar results to those of uncomplicated PCIOL cases. Although further studies are needed to gain more accurate information on this subject, it seems that DSAEK can be performed while retaining an ACIOL with favorable results.

The quantum of thermal conductance of ballistic (collisionless) one-dimensional channels is a unique fundamental constant. Although the quantization of the electrical conductance of one-dimensional ballistic conductors has long been experimentally established, demonstrating the quantization of thermal conductance has been challenging as it necessitated an accurate measurement of very small temperature increase. It has been accomplished for weakly interacting systems of phonons, photons and electronic Fermi liquids; however, it should theoretically also hold in strongly interacting systems, such as those in which the fractional quantum Hall effect is observed. This effect describes the fractionalization of electrons into anyons and chargeless quasiparticles, which in some cases can be Majorana fermions. Because the bulk is incompressible in the fractional quantum Hall regime, it is not expected to contribute substantially to the thermal conductance, which is instead determined by chiral, one-dimensional edge modes. The thermal conductance thus reflects the topological properties of the fractional quantum Hall electronic system, to which measurements of the electrical conductance give no access. Here we report measurements of thermal conductance in particle-like (Laughlin-Jain series) states and the more complex (and less studied) hole-like states in a high-mobility two-dimensional electron gas in GaAs-AlGaAs heterostructures. Hole-like states, which have fractional Landau-level fillings of 1/2 to 1, support downstream charged modes as well as upstream neutral modes, and are expected to have a thermal conductance that is determined by the net chirality of all of their downstream and upstream edge modes. Our results establish the universality of the quantization of thermal conductance for fractionally charged and neutral modes. Measurements of anyonic heat flow provide access to information that is not easily accessible from measurements of conductance.

PURPOSE To compare measurements of axial length (AL), anterior chamber depth (ACD), keratometry (K), and the refractive predictability of the Aladdin and IOLMaster biometry devices in cataract surgery patients. METHODS A retrospective observational study of eyes undergoing cataract surgery. Data were retrieved on AL, ACD, and K measurements obtained by the Aladdin and the IOLMaster. Furthermore, the postoperative refractive prediction errors were compared between the devices. RESULTS The study included 127 consecutive eyes of 127 patients undergoing cataract surgery. Mean measurements of AL were not significantly different between the Aladdin (24.18 ± 1.89 mm) and IOLMaster (24.18 ± 1.89 mm) (p = 0.792). Mean K measurements were different between Aladdin (43.84 ± 1.56 D) and IOLMaster (43.97 ± 1.61 D) (p < 0.001). For AL, Aladdin measurements correlated strongly with IOLMaster measurements (r = 0.9997). For K, Aladdin measurements correlated strongly with IOLMaster measurements (r = 0.9912). Fifty-eight of the 127 eyes underwent cataract surgery with a monofocal intraocular lens. For these, mean absolute error (MAE) in predicting refraction relative to the measured postoperative refraction differed between Aladdin (MAE = 0.54 ± 0.40D) and IOLMaster (MAE = 0.49 ± 0.41D) (p = 0.001). After adjustment for the systematic difference in K measurements, the difference in MAE was no longer significant (p = 0.601). The ACD measurements did not differ significantly (p = 0.873) and were well correlated (r = 0.8327). CONCLUSIONS A very good correlation was found in AL, K, and ACD measurements between the Aladdin biometer and the IOLMaster. Minimal adjustment for the constant difference in keratometry measurements matched the refractive predictability of both devices.

To evaluate the visual outcomes of photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) in amblyopic eyes.Care Vision Refractive Clinic, Tel Aviv, Israel.Retrospective case series.Amblyopic eyes of patients with a preoperative corrected distance visual acuity (CDVA) of 20/33 or worse had PRK or LASIK. Postoperative visual outcomes (uncorrected distance visual acuity, CDVA) and correlations with age, preoperative CDVA, refractive error type, astigmatism grade, procedure type, laser suite model, amblyopia grade, and amblyopia type were analyzed.This study evaluated 327 eyes (327 patients). The CDVA improved more than 1, 2, and 3 Snellen lines in 147 eyes (45.0%), 75 eyes (22.9%), and 32 eyes (9.8%), respectively. Age (P = .007, B = 0.002), and preoperative CDVA (P .001, B = -0.405) were significantly associated with CDVA improvement. The outcome in eyes with lower myopia was significantly better than in eyes with hyperopia (0.054 logMAR difference; P = .016) or high myopia (0.036 logMAR difference; P = .002). Moderately amblyopic eyes had significantly better visual outcomes than mildly amblyopic eyes (0.038 logMAR difference; P = .001). No significant difference was found between PRK and LASIK (P = .262).Laser vision correction, regardless of the type of procedure (LASIK or PRK) might improve CDVA in a large portion of amblyopic patients. Improvement was greater in younger patients, eyes with lower initial CDVA, and eyes with lower myopia.

BACKGROUND Idiopathic intracranial hypertension (IIH) is a well-characterized syndrome, most commonly affecting obese women of childbearing age. Differences in its prevalence have been reported in various populations. The aim of this article was to determine whether differences in clinical presentation and management exist for patients with IIH between different regions the world. METHODS Retrospective database analysis of adult patients with IIH from 4 different neuro-ophthalmology clinics. The data collected included gender, age of onset, body mass index (BMI), lumbar puncture opening pressure, initial visual acuity (VA), initial visual field (VF) mean deviation (MD), pharmacological or surgical treatment, length of follow-up, final VA, and final VF MD. RESULTS The study population consisted of 244 patients, with significant regional variations of female to male ratio. Overall, there was no significant difference regarding the age of diagnosis or the BMI. Acetazolamide was the first line of treatment in all groups but there was a difference between countries regarding second-line treatment, including the use of surgical interventions. Mean initial VA differed between groups but the final change in VA was the same among all the study groups. CONCLUSIONS There are differences in IIH presentation, treatment, and response to therapy among different countries. International prospective studies involving multiple centers are needed to determine the potential influence of environmental and genetic factors on the development of IIH and to improve the management of this potentially blinding disorder.

To compare the standard Ishihara booklet with color-vision-testing smartphone applications.A prospective observational diagnostic study on 42 normal trichromats and 38 color-deficient subjects. Patients were presented with three color vision tests in random order: an Ishihara test booklet and two color-vision-testing smartphone applications: Eye2Phone and the Color Vision Test application (CVT app). Sensitivity and specificity of the electronic tests was compared with Ishihara results, and in each one of these applications every plate was individually analyzed for success/failure rate.Average age was 42.7 ± 12.9 years. There were 57 males (71.2%). Sensitivity and specificity of each test was 100% (38/38) and 95.2% (40/42) for the Eye2Phone, and 100% (38/38) and 54.8% (23/42) for the CVT app. There was no significant difference between the Ishihara booklet and the Eye2Phone (p = 0.500), with a high kappa measure of agreement (0.950, p0.001). The CVT app was significantly different than both other tests (p0.001) with a low kappa measure of agreement (0.535 with the Ishihara and 0.575 with the Eye2Phone). Of the 21 tested plates, color-deficient subjects failed 11.8 ± 3.1 plates in the Ishihara booklet and 14.1 ± 2.1 plates in the Eye2Phone (p0.001). Significant plate-specific differences for the color-deficient group were found in plate numbers 3, 6, 7, 8, 9, 15, and 16. Both tests were poorly able to give an indication of the specific dichromatism type. The Ishihara booklet was rated more comfortable and clearer than the Eye2Phone in color-deficient subjects. The CVT app was rated lowest for comfort and clarity in both groups.Smartphone applications testing for color vision deficiency are readily available; however, users of these apps should be aware that some may have different sensitivity for detection of color vision deficiency compared to Ishihara booklet, limiting their usefulness for clinical use. Therefore, further validation of these applications is required.

Studies of electronic interferometers, based on edge-channel transport in the quantum Hall effect regime, have been stimulated by the search for evidence of abelian and non-abelian anyonic statistics of fractional charges. In particular, the electronic Fabry–Pérot interferometer has been found to be Coulomb dominated, thus masking coherent Aharonov–Bohm interference patterns: the flux trapped within the interferometer remains unchanged as the applied magnetic field is varied, barring unobservable modulations of the interference area. Here we report on conductance measurements indicative of the interferometer's area ‘breathing' with the variation of the magnetic field, associated with observable (a fraction of a flux quantum) variations of the trapped flux. This is the result of partial (controlled) screening of Coulomb interactions. Our results introduce a novel experimental tool for probing anyonic statistics., Quantum Hall liquids play host to a wide range of unusual physics. Here, the authors use an electronic Fabry-Pérot interferometer to observe modulations of a quantum Hall liquid's area, which can offer a means to study the statistics of fractional charges.

Objective To understand and evaluate the skills primary care physicians need to convey bad news, from both the patients’ as well as the physicians’ points of view. These data were used to formulate clinical guidelines about conveying bad news.

Objective We created a workshop to teach medical students how to convey bad news. We wanted to determine the most appropriate time during training for the workshop to be given — during the pre-clinical phase or during the clinical phase.

To evaluate the efficacy of the BinoVision home system as measured by improvement of visual acuity in the patient's amblyopic eye.An open-label prospective pilot-trial of the system was conducted with amblyopic children aged 4-8 years at the pediatric ophthalmology unit, Tel-Aviv Medical Center, January 2014 to October 2015. Participants were assigned to the study or sham group for treatment with BinoVision for 8 or 12 weeks. Patients were instructed to watch animated television shows and videos at home using the BinoVision device for 60 minutes, 6 days a week. The BinoVision program incorporates elements at different contrast and brightness levels for both eyes, weak eye tracking training by superimposed screen images, and weak eye flicker stimuli with alerting sound manipulations. Patients were examined at 4, 8, 12, 24, and 36 weeks.A total of 27 children were recruited (14 boys), with 19 in the treatment group. Median age was 5 years (range, 4-8 years). Mean visual acuity improved by 0.26 logMAR lines in the treatment group from baseline to 12 weeks. Visual acuity was improved compared to baseline during all study and follow-up appointments (P 0.01), with stabilization of visual acuity after cessation of treatment. The sham group completed 4 weeks of sham protocol with no change in visual acuity (P = 0.285). The average compliance rate was 88% ± 16% (50% to 100%) in treatment group.This pilot trial of 12 weeks of amblyopia treatment with the BinoVision home system demonstrated significant improvement in patients' visual acuity.

Purpose To study high-resolution ultrasound biomicroscopy (UBM) findings in anterior scleral inflammatory disease and evaluate the efficacy of high-resolution UBM as an adjunctive diagnostic tool. Methods A cross-sectional study. The medical records of 30 patients (33 eyes) with episcleritis or anterior scleritis were reviewed for clinical features and high-resolution UBM findings. Ultrasound biomicroscopy (UBM) examination was performed using 50 MHz Aviso S (Quantel Medical, Clermont-Ferrand, France). Results Seventeen eyes had episcleritis [nodular (12), simple (five)], and 16 eyes had anterior scleritis [nodular (14), diffuse (two)] as classified by UBM. The use of high-resolution UBM allowed high-resolution imaging of the sclera and episclera and showed characteristic patterns of episcleritis and anterior scleritis. The clinical classification matched UBM findings in 25 (76%) eyes. In the other eight eyes (24%), UBM analysis led to a change in the final classification: four eyes with suspected episcleritis were classified with scleritis, and four eyes with suspected scleritis were classified with episcleritis. Eleven patients (36.7%) had an associated systemic disease. Conclusion High-resolution UBM enabled visualization of distinct imaging findings of episcleritis and anterior scleritis, indicating its usefulness in the classification of challenging cases of anterior scleral inflammatory disease.

BACKGROUND AND OBJECTIVE: To assess eyes with flat, irregular retinal pigment epithelial detachments (RPEDs) associated with central serous chorioretinopathy (CSCR) for choroidal neovascularization (CNV) using optical coherence tomography angiography (OCTA). MATERIALS AND METHODS: Retrospective review of OCTA images of chronic CSCR eyes with irregular RPED (group 1) and regular RPED (controls, group 2) for presence of CNV, subretinal fluid, and intraretinal fluid. Fluorescein angiography was also evaluated for CNV. RESULTS: CNV was detected using OCTA in 13 of 31 eyes (41.9%) in group 1 and in one of 18 eyes (5.6%) in group 2 ( P = .007). Irregular RPED was a risk factor for CNV (odds ratio [OR] = 12.28; 95% CI, 1.45–104.3). There was no significant difference between detection by OCTA and FA ( P = 1.0). Sensitivity and specificity of detection by OCTA were 85.7% and 95.7%, respectively. CONCLUSIONS: Irregular RPEDs in chronic CSCR eyes may harbor neovascularization more often than previously thought, which has implications on therapy.
