Background: Intravitreal anti-vascular endothelial growth factor (VEGF) is the standard treatment for exudative age-related macular degeneration (AMD). The constitution of the vitreomacular interface varies greatly in cases of attached (with or without traction) or detached vitreous body, which can impact the effectiveness of the anti-VEGF treatment., Objective: Based on the current literature this article displays the current state of the science on whether the constitution of the vitreous body has an effect on the anti-VEGF treatment., Material and Methods: The published data extracted from current trials and post hoc analyses concerning this topic are presented and put into the clinical context., Results: The presence of a vitreomacular adhesion reduces the efficacy of anti-VEGF treatment of exudative AMD. Posterior vitreous body detachment represents a positive prognostic factor concerning the efficacy of anti-VEGF treatment but not necessarily the prognosis for visual acuity., Conclusion: Patients with attached vitreous body need a more intensive treatment monitoring compared to patients with detached vitreous body. Therefore, in eyes with initial posterior vitreous body detachment receiving a treat and extend regimen, the interval between anti-VEGF injections can be extended to 4 instead of 2 weeks without endangering the success of treatment., (© 2023.

Intravitreal injection treatment for the management of macular edema as an expression of increased capillary permeability and leakage constitute the mainstay of treatment in retinal vein occlusion. In contrast to diabetic retinopathy or neovascular age-related macular degeneration, permanent and complete functional and morphological restoration can be achieved, as retinal vein occlusions are usually associated with risk factors, but do not represent the manifestation form of an underlying systemic or degenerative chronic disorder; however, successful long-term management of retinal vein occlusion -associated macular edema usually requires intensive and also long-term continued treatment with vascular endothelial growth factor (VEGF) inhibitors or with a less favorable side effect profile, dexamethasone. A functional treatment success can be maintained over the long term by both pro re nata (PRN) or treat and extend (T&E) regimens. In contrast, according to the currently available data, the combination of anti-VEGF administration and grid laser treatment has no additional benefit compared to monotherapy. In patients with recalcitrant macular edema, switching to another intravitreal agent may be considered during the course of treatment, although a true therapeutic benefit with respect to the development of visual acuity has not yet been proven. The current review summarizes the relevant aspects in the management of RVO-associated macular edema and provides the foundations for the application of successful treatment strategies., (© 2022.

Background: The Retina.net ROP registry documents data of preterm infants developing stages of retinopathy of prematurity (ROP) that need ROP treatment. The aim of this analysis was to investigate data regarding epidemiology, therapy and changes over time (15 years) in a single participating center (Hannover Medical School, MHH)., Methods: Analysis of data of infants treated for ROP at a single center over time (birth 2001-2016, ROP treatment in 2002-2017)., Results: Overall, 65 infants were treated (23 female). In 11 infants (16.9%) ROP screening was conducted externally and infants were transferred to the MHH for ROP treatment. Between 2006 and 2016, incidence of ROP requiring treatment among infants screened for the development of ROP was 4.1%. Mean gestational age was 25.7 weeks (standard deviation, SD 1.8), mean birth weight 763 g (SD 235), postmenstrual age at treatment 38.2 weeks (SD 3.2), postnatal age 12.4 weeks (SD 3.2). There was no significant change in parameters over time. ROP zone II, stage 3+ was most frequently treated (57 eyes of 31 infants). 58 infants were treated with laser (114 eyes), 7 infants were treated with anti-VEGF (bevacizumab, bilateral, 14 eyes) from 2014 onwards. Retreatment due to recurrence of ROP was necessary in one infant after initial laser coagulation. Infants with ROP requiring treatment often presented with neonatal comorbidities, ventilation in more than 90%, bronchopulmonary dysplasia, and received transfusions., Conclusion: This is the first monocentric analysis over 15 years originating from the Retina.net ROP registry. In this cohort we see a change in ROP therapy from laser coagulation to anti-VEGF (bevacizumab) from 2014 onwards, demographic data and treatment parameters remained relatively stable over time., (© 2021.

Background: Regular treatment with intravitreal operative medication injections (IVOM) and the associated frequent check-ups are a major challenge for many patients, which can lead to treatment discontinuation. The aim of the modified treat and extend (TAE) in blocks scheme is to achieve stable retinal and visual outcomes with as few control visits as possible and thus to minimize the burden for the individual patient., Methods: This monocentric retrospective study examined the treatment courses of 387 patients with neovascular age-related macular degeneration, diabetic macular edema and retinal vein occlusion, who were treated by three blocks of intravitreal injections in the TAE regimen. The primary endpoint was achieving an injection interval of 12 weeks., Results: Intravitreal injections in TAE blocks significantly reduced retinal thickness and improved visual acuity. On average, a treatment interval of 2 months was achieved across the various indications., Conclusion: Intravitreal injections in TAE blocks of three injections can reduce patients' burden and lead to stable retinal and visual results.

Background: Multimodal imaging of retinal angiomatous proliferation (RAP) lesions (type 3 neovascularization) and the diagnostic significance of optical coherence tomography angiography (OCT-A)., Material and Methods: Confirmation of the diagnosis in six case reports with fundus photography, optical coherence tomography (OCT), fluorescein angiography (FLA), indocyanine green angiography (ICGA) and optical coherence tomography angiography (OCT‑A)., Results and Conclusion: The use of OCT‑A is helpful for the diagnosis and follow-up examinations of RAP lesions (type 3 neovascularization). It enables the detailed visualization of intraretinal and choroidal microcirculation. Furthermore, it is possible to evaluate the progression, classify the stages and comprehend the treatment strategy.

Background: Trabeculectomy is the most frequent form of glaucoma surgery. Despite the intraoperative use of antimetabolites, such as mitomycin C (MMC) postoperative scarring reactions can cause surgical failure. The subconjunctival placement of an Ologen® implant can avoid wound scarring. The additional application of bevacizumab should reduce angiogenesis and thereby scarring reactions and improve the surgical success rate., Methods: This was a retrospective single center study of patients with glaucoma after trabeculectomy with MMC. The operation was carried out either without an Ologen® implant (group 1), or with an Ologen® implant as an bevacizumab depot (group 2) or with an Ologen® implant and intrachamber injection of bevacizumab (group 3). The follow-up postoperative observation of intraocular pressure (IOP), complications, subsequent interventions and antiglaucoma treatment was performed for 12 months., Results: There were no significant differences between the groups with respect to IOP, complications, subsequent interventions and postoperative antiglaucoma treatment. The highest success rate (IOP after 12 months ≤15 mm Hg without treatment) was in group 1 (77.5%), followed by group 2 with 63.6% and group 3 with 57.1% (p = 0.34, χ 2 -test)., Conclusion: The highest success rate was achieved in group 1 with MMC but without an Ologen® implant or bevacizumab. In this study the additional use of Ologen® implants and bevacizumab in trabeculectomy was found to be a safe operation method but did not provide any additional benefits.

The diagnostic findings, therapy and course of disease are described for a case of central venous occlusion in Wyburn-Mason-Syndrome. The diagnosis was based on OCT, fluorescein angiography and cMRI. In addition, due to the macular edema an intravitreal injection with Ranibizumab was applied. The macular edema regressed and further Ranibizumab-injections as well as a panretinal laser-coagulation and possibly a cryocoagulation were planned. For a central venous occlusion with macular edema also in Wyburn-Mason-Syndrome an intravitreal anti-VEGF-inhibition leads to an improvement.

Background: Currently only few data are available on the treatment reality with ranibizumab in patients with diabetic macular edema (DME)., Material and Methods: POLARIS is an international observational study which included 983 patients who were treated with ranibizumab due to DME. The primary objective of the study was to investigate the influence of treatment and control intervals as well as resource utilization on the mean change in visual acuity. Secondary endpoints included the collation of disease activity monitoring in the clinical practice. This article describes the results of the German POLARIS population. The study was conducted in 8 European countries from October 2012 to January 2015., Results: In Germany 220 patients were included in the study. Visual acuity improved by 4.3 letters within the first 3 months of treatment. At 12 months, visual acuity increased on average by 4.1 (SD ± 12.4) letters (approximately 1 line) for 168 patients enrolled in the efficacy analysis. Patients received an average of 4.5 (SD ± 1.9) injections, 10.3 (SD ± 6.3) visual acuity tests and 3.3 (SD ± 3.1) optical coherence tomography (OCT) examinations during the first year. Patients with ≤3 injections showed an average improvement in visual acuity by 2.7 letters which was less improvement compared to patients with >3 injections, who achieved an average improvement of 5.4 letters. There was a correlation between the number of injections and the visual acuity achieved., Discussion: For Germany, the results of the POLARIS study indicate that despite a high number of visits, patients with DME are undertreated in clinical routine practice. The injection frequency in Germany was lower than in randomized clinical trials. Almost half of the patients received less than 4 injections in the first year of treatment and thus showed an undertreatment compared to the recommendations of German and international medical societies.

This article presents a case of endophthalmitis after intravitreal injection with bevacizumab (Avastin®) in a patient suffering from exudative age-related macular degeneration (AMD). Within 1h after diagnosis the patient underwent vitrectomy with intravitreal injection of antibiotics combined with corticosteroids and 4 weeks after the endophthalmitis the visual acuity increased to 0.5. This case report demonstrates that an immediate vitrectomy combining intravitreal injection of medication can lead to a good visual outcome even in the case of severe endophthalmitis.

Background: Critical prerequisites for successful therapy of neovascular age-related macular degeneration (nvAMD) are an early initiation and continuous monitoring; however, delays in starting therapy and non-medically indicated discontinuation of therapy are frequent, which limits therapy efficacy and, thus, visual outcomes., Objective: To identify the reasons for delay in therapy and non-medically indicated termination of therapy., Material and Methods: Patients who had started a new therapy (starters) and those who independently terminated therapy (dropouts) were interviewed by telephone with a specific, standardized questionnaire. Results were summarized descriptively., Results: A total of 100 starters and 55 dropouts were interviewed. The mean therapy delay was 22 (±28 SD) days. This was mainly due to the time until the decision to see an ophthalmologist was made. Main reasons for dropping out were: transportation issues (27%), poor general health (25%) and the assumption that there is no benefit from therapy (11%). Of the patients who dropped out 63% would have liked to continue therapy., Conclusion: There is potential for improvement in nvAMD management regarding therapy start as well as therapy maintenance. Sensitizing for initial nvAMD symptoms is important as is reduction of barriers to therapy maintenance, since most therapy dropouts would like to continue the therapy.

Background: The ratio of choroidal neovascularization (CNV) and pigment epithelium detachment (PED) represents an important parameter regarding the risk of developing a tear of the retinal pigment epithelium (RPE) in patients with vascularized PED due to age-related macular degeneration (AMD)., Methods: Within the framework of the RECOVER study a total of 29 treatment-naive patients with vascularized PED underwent fluorescein angiography (FA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT) volume scans. The CNV-PED ratio was evaluated retrospectively by two independent graders in three ways: 1) manually based on the en face image of the FA late phase and 2) manually based on the en face image of the ICGA late phase. 3) In every OCT scan encompassing the PED, the area between the RPE and Bruch's membrane and the CNV area was measured and multiplied by the distance between OCT scans in order to determine volumetric data of CNV, PED and the serous cavity., Results: The FA and ICGA showed a mean serous area of 6.14 ± 4.21 mm 2 (ICGA 5.94 ± 4.13 mm 2 ), a mean CNV area of 3.25 ± 1.79 mm 2 (ICGA 2.84 ± 1.68 mm 2 ) and a mean PED area of 9.39 ± 4.27 mm 2 (ICGA 8.79 ± 4.23 mm 2 ) resulting in a mean two-dimensional morphological ratio of 0.35 ± 0.21 (ICGA 0.32 ± 0.22). The volumetric measurement revealed a mean CNV volume of 0.63 ± 0.67 mm 3 , a mean serous volume of 3.61 ± 3.83 mm 3 and a mean total PED volume of 4.25 ± 3.68 mm 3 . The mean three-dimensional morphological ratio was 0.15 ± 0.29. The difference between the two-dimensional ratios of FA (p < 0.0001) and ICGA (p = 0.0004) was significant compared to the three-dimensional OCT ratio., Conclusion: Assessment of the CNV-PED ratio using volumetric OCT measurements is an additional tool to the en face modalities FA and ICGA. This seems to be clinically relevant regarding the risk stratification of RPE tear development in PED patients and for the planning of the treatment regimen.

Background: Retinopathy of prematurity (ROP) is one of the main reasons for childhood blindness. The number of infants requiring treatment, however, is low for individual centers. The Retina.net ROP registry has been founded to allow a joint analysis of treatment patterns and courses post treatment., Objective: This paper reports treatment patterns over 5 years., Material and Methods: All infants born between January 2011 and December 2015 who were entered into the treatment registry by one of the 12 participating centers were analyzed., Results: The data of 150 infants (292 eyes) were analyzed and ROP 3+ in zone II was the most prevalent treatment indication. Gestational age and birth weight remained stable over the years. The treatment patterns, however, changed with anti-VEGF treatment (bevacizumab or ranibizumab) accounting for only 10% of treated eyes in 2011 but for 56% and 30% in 2014 and 2015, respectively. Almost all eyes with AP-ROP or zone I disease received anti-VEGF treatment. Zone II disease was predominantly treated with laser photocoagulation. Recurrences were more common and appeared later in the anti-VEGF group compared to the laser group (23%/interval 60 days vs. 17%/interval 23 days). Perioperative complications were evenly distributed across treatment groups., Conclusion: The data in this analysis represent about 10-15% of treated infants in Germany. The results provide evidence for an increasing use of anti-VEGF agents for ROP. The data reflect a selection bias for anti-VEGF treatment in eyes with a more aggressive disease. This needs to be considered when interpreting data such as disease recurrence rates. The risk for late recurrences after anti-VEGF treatment is of particular clinical significance.

Purpose: Approach to loss of visual acuity in a patient with a choroidal osteoma (CO) which had been stable for seven years., Methods: Fluorescence angiography confirmed a choroidal neovascularization (CNV) as the cause of the loss of visual acuity. Treatment with intravitreal (IVT) injection of ranibizumab., Results: Increase of visual acuity and decrease of edema after IVT injection., Conclusion: Monitoring is necessary even for primarily benign CO in order to detect secondary complications causing loss of visual acuity, e. g. secondary CNV. Anti-VEGF IVT represents an approved treatment option.

Background: The prevalence of blindness as defined by law could be reduced by the introduction of anti-vascular endothelial growth factor (VEGF) therapy. Because the treatment is governed by patient needs, mostly using morphological criteria, imaging diagnostics are of particular importance. The non-interventional OCEAN study investigates the treatment with ranibizumab in the clinical routine practice. In a subgroup of patients the interpretation of spectral domain optical coherence tomography (SD-OCT) scans by the treating physicians will be analyzed (ORCA module)., Methods: Over a period of 24 months data from patients with exudative age-related macular degeneration (AMD), macular edema due to retinal vein occlusion or diabetes mellitus, who are receiving intravitreal injections of ranibizumab, will be assessed. Information on examinations, visual acuity, treatment and recordings from imaging techniques will be documented using a questionnaire. The SD-OCT scans, fluorescence angiography and fundus photography will be independently analyzed by the ophthalmologist of the study center and by three reading centers (CIRCL Cologne, GRADE Bonn and M3 Münster). Automated measurements of retinal thickness by the manufacturers' software will be checked and if necessary manually corrected. A qualitative interpretation in terms of morphological criteria for (further) treatment will be performed., Conclusion: A thorough assessment of SD-OCT images during anti-VEGF therapy provides the basis for the best possible needs-oriented treatment regimen. The control of the quality of data from daily routine practice may indicate possible weaknesses allowing explicit training and therefore optimization of patient treatment.
