    Abstract: One of the biggest challenges when using anti–vascular endothelial growth factor (VEGF) agents to treat retinopathy of prematurity (ROP) is the need to perform long-term follow-up examinations to identify eyes at risk of ROP reactivation requiring retreatment. Objective To evaluate whether an artificial intelligence (AI)–based vascular severity score (VSS) can be used to analyze ROP regression and reactivation after anti-VEGF treatment and potentially identify eyes at risk of ROP reactivation requiring retreatment. Design, Setting, and Participants This prognostic study was a secondary analysis of posterior pole fundus images collected during the multicenter, double-blind, investigator-initiated Comparing Alternative Ranibizumab Dosages for Safety and Efficacy in Retinopathy of Prematurity (CARE-ROP) randomized clinical trial, which compared 2 different doses of ranibizumab (0.12 mg vs 0.20 mg) for the treatment of ROP. The CARE-ROP trial screened and enrolled infants between September 5, 2014, and July 14, 2016. A total of 1046 wide-angle fundus images obtained from 19 infants at predefined study time points were analyzed. The analyses of VSS were performed between January 20, 2021, and November 18, 2022. Interventions An AI-based algorithm assigned a VSS between 1 (normal) and 9 (most severe) to fundus images. Main Outcomes and Measures Analysis of VSS in infants with ROP over time and VSS comparisons between the 2 treatment groups (0.12 mg vs 0.20 mg of ranibizumab) and between infants who did and did not receive retreatment for ROP reactivation. Results Among 19 infants with ROP in the CARE-ROP randomized clinical trial, the median (range) postmenstrual age at first treatment was 36.4 (34.7-39.7) weeks; 10 infants (52.6%) were male, and 18 (94.7%) were White. The mean (SD) VSS was 6.7 (1.9) at baseline and significantly decreased to 2.7 (1.9) at week 1 ( P   & amp;lt; .001) and 2.9 (1.3) at week 4 ( P   & amp;lt; .001). The mean (SD) VSS of infants with ROP reactivation requiring retreatment was 6.5 (1.9) at the time of retreatment, which was significantly higher than the VSS at week 4 ( P   & amp;lt; .001). No significant difference was found in VSS between the 2 treatment groups, but the change in VSS between baseline and week 1 was higher for infants who later required retreatment (mean [SD], 7.8 [1.3] at baseline vs 1.7 [0.7] at week 1) vs infants who did not (mean [SD] , 6.4 [1.9] at baseline vs 3.0 [2.0] at week 1). In eyes requiring retreatment, higher baseline VSS was correlated with earlier time of retreatment (Pearson r  = −0.9997; P   & amp;lt; .001). Conclusions and Relevance In this study, VSS decreased after ranibizumab treatment, consistent with clinical disease regression. In cases of ROP reactivation requiring retreatment, VSS increased again to values comparable with baseline values. In addition, a greater change in VSS during the first week after initial treatment was found to be associated with a higher risk of later ROP reactivation, and high baseline VSS was correlated with earlier retreatment. These findings may have implications for monitoring ROP regression and reactivation after anti-VEGF treatment.

    Abstract: Macular edema (ME) is the most frequent vision threatening consequence after retinal vein occlusion (RVO). In this study, we evaluate the effect of dexamethasone intravitreal implants (DII, Ozurdex) in a real-life cohort of 99 patients with ME due to RVO. All patients who received DII for ME following RVO between 2011 and 2016 at the University Eye Hospital Freiburg, Germany and who had fully accessible electronic medical records were eligible for this study. Most of the patients included in this study were not treatment-naïve: 61 eyes had received prior anti-VEGF drugs, 6 eyes had received intravitreal corticosteroids (triamcinolone) and 15 had been treated with both; 17 eyes were treatment-naïve. Mean follow-up was 312 ± 310 days. Mean visual acuity (VA) was maintained throughout the observation period (mean VA at baseline: 66.7 ± 23.5 letters; at last observation 64.9 ± 28.3). Central retinal thickness (CRT) decreased from 526 ± 179 µm at baseline to 431 ± 199 µm. Mean intraocular pressure (IOP) increased from 14.4 ± 3.1 mmHg at baseline to 17.1 ± 6.3 mmHg. Cataract surgery was performed in 22% of phakic eyes. DII was used as second-line treatment in the majority of cases in this cohort. The fact that mean VA remained unchanged while mean CRT decreased illustrates that morphologic improvement does not always translate into functional gain. Mean IOP was maintained within normal limits and cataract formation was as expected in this age group.

    Abstract: In 2018, IDx-DR was approved as a method to determine the degree of diabetic retinopathy (DR) using artificial intelligence (AI) by the FDA. Methods We integrated IDx-DR into the consultation at a diabetology focus clinic and report the agreement between IDx-DR and fundoscopy as well as IDx-DR and ophthalmological image assessment and the influence of different camera systems. Results Adequate image quality in miosis was achieved more frequently with the Topcon camera ( n  = 456; NW400, Topcon Medical Systems, Oakland, NJ, USA) compared with the Zeiss camera ( n  = 47; Zeiss VISUCAM 500, Carl Zeiss Meditec AG, Jena, Germany). Overall, IDx-DR analysis in miosis was possible in approximately 60% of the patients. All patients in whom IDx-DR analysis in miosis was not possible could be assessed by fundoscopy with dilated pupils. Within the group of images that could be evaluated, there was agreement between IDx-DR and ophthalmic fundoscopy in approximately 55%, overestimation of severity by IDx-DR in approximately 40% and underestimation in approximately 4%. The sensitivity (specificity) for detecting severe retinopathy requiring treatment was 95.7% (89.1%) for cases with fundus images that could be evaluated and 65.2% (66.7%) when all cases were considered (including those without images in miosis which could be evaluated). The kappa coefficient of 0.334 ( p   〈  0.001) shows sufficient agreement between IDx-DR and physician’s image analysis based on the fundus photograph, considering all patients with IDx-DR analysis that could be evaluated. The comparison between IDx-DR and the physician’s funduscopy under the same conditions shows a low agreement with a kappa value of 0.168 ( p   〈  0.001). Conclusion The present study shows the possibilities and limitations of AI-assisted DR screening. A major limitation is that sufficient images cannot be obtained in miosis in approximately 40% of patients. When sufficient images were available the IDx-DR and ophthalmological diagnosis matched in more than 50% of cases. Underestimation of severity by IDx-DR occurred only rarely. For integration into an ophthalmologist’s practice, this system seems suitable. Without access to an ophthalmologist the high rate of insufficient images in miosis represents an important limitation.

    Abstract: Einführung Special Olympics Deutschland (SOD) ist die deutsche Organisation der weltweit größten Sportbewegung für Menschen mit geistiger und mehrfacher Behinderung: Viele Landesverbände von SOD bieten mittlerweile alle 4 Jahre Sommerspiele für diese Klientel an, an denen Kinder und Erwachsene aus dem jeweiligen Bundesland teilnehmen. Während der Landessommerspiele von SO Baden-Württemberg in Offenburg im Jahr 2017 konnten die Athletinnen und Athleten im Rahmen des Gesundheitsprogramms „Opening Eyes – Besser Sehen“ an einem augenärztlichen Screening teilnehmen. Methoden Optiker und Optometristen erhoben die Anamnese und Refraktion, prüften auf Farbfehlsichtigkeiten, Sehschärfe (Ferne und Nähe) sowie den orthoptischen Status. Insgesamt 4 erfahrene Ärzte in Weiterbildung und Fachärzte der Klinik für Augenheilkunde des Universitätsklinikums Freiburg führten Spaltlampenuntersuchungen, Funduskopie und Augendruckmessungen durch. Bei Bedarf wurde eine Funduskopie in Mydriase bzw. eine OCT-Untersuchung angeschlossen. Ergebnisse Insgesamt wurden 166 Personen untersucht (48% weiblich = 80; 52% männlich = 86). Der Abdecktest war in etwa 45% der Fälle in der Ferne und in 47% der Fälle in der Nähe auffällig. Sechs bzw. 11% der Patienten gaben Doppelbilder an (9/156; 17/156; jeweils Ferne und Nähe). Eine auffällige Farbsehprüfung mit weniger als 9 von 9 erkannten CVTM-Testtafeln (Color Vision Testing Made Easy nach Waggoner) wurde bei 8% (11/143) dokumentiert. Fundusauffälligkeiten sahen wir in 13% der Fälle (16/125). 41% (48/118) benötigten eine neue Brillenverschreibung. 29% (45/157) gaben eine Überempfindlichkeit gegenüber Licht an. Jeder 2. Teilnehmer hatte in den letzten 3 Jahren einen Augenarzttermin wahrgenommen; dennoch ergab die Erhebung in 10% (16/160), dass noch kein Augenarztbesuch stattgefunden hatte. In 4% der Fälle wurde eine notfallmäßige Vorstellung beim niedergelassenen Augenarzt empfohlen (z. B. im Falle eines akuten Keratokonus oder aufgrund eines erhöhten Augeninnendrucks). Eine optionale Behandlung (z. B. wegen eines Trockenen Auges) wurde in 40% der Fälle (66/166) empfohlen. Diskussion Menschen mit geistiger Behinderung beklagen allgemeine Probleme mit den Augen oder neu aufgetretene Sehprobleme nicht zwangsläufig und unmittelbar. Zusätzlich besteht möglicherweise ein eingeschränkter Zugang zur augenärztlichen Versorgung im Vergleich zu Menschen ohne geistige Behinderung. Aufgrund der 4% behandlungsbedürftiger Diagnosen sowie der 53% der Teilnehmer mit nicht optimalem Refraktionsausgleich erscheint eine augenärztliche Begleitung von Special Olympics sinnvoll, sollte verstetigt und mit öffentlichen Mitteln unterstützt werden.

    Abstract: 〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 The German Registry of central serous chorioretinopathy (CSC) collects data on CSC patients in a nationwide multicenter approach to analyze epidemiology, risk factors, clinical presentations, as well as diagnosis and treatment patterns. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 In this multicenter cohort study, patients with CSC were enrolled in nine tertiary referral centers in Germany between January 2022 and June 2023. After consenting to the study, demographic data, risk factors, reported symptoms, best-corrected visual acuity (BCVA), funduscopic findings, disease severity, and diagnostic and treatment decisions were recorded and analyzed. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 A total of 539 eyes of 411 CSC patients were enrolled in this study including 308 males (75%) and 103 females (25%). Patients were predominantly of Caucasian origin and had a mean age of 55.5 years (IQR 41.0–70.0). 28% of eyes were classified as acute ( & lt;4 months duration) CSC, 28% as chronic ( & gt;4 months duration) CSC, 21% as inactive CSC, 11% as chronic atrophic CSC, and 12% as CSC with secondary CNV. 128 patients (31%) demonstrated bilateral CSC. The most common risk factors reported were psychological stress (52%), smoking (38%), arterial hypertension (38%), and a history of or current use of steroids (30%). Most frequently encountered symptoms included decreased visual acuity (76%), metamorphopsia (49%), relative scotoma (47%), blurred vision (19%), and dyschromatopsia (9%). The mean logMAR BCVA on initial examination was 0.2 (≈20/30, IQR 0.2–0.4) but showed significant variation with a tendency of lower BCVA in chronic cases. At the baseline visit, 74% of the overall cohort received no treatment, while 19% underwent local treatment and only 2% underwent systemic treatment. Of the local therapies, anti-VEGF injections were the most frequently performed procedure (33%, mainly for secondary CNV), followed by micropulse laser (28%), focal nonpulsed laser (23%), verteporfin photodynamic therapy (14%), and nonsteroidal anti-inflammatory eye drops (2%). Among intravitreal anti-VEGF agents, aflibercept was used most frequently, followed by bevacizumab and ranibizumab. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 This registry represents one of the largest cohorts of European patients with CSC to date. Patient age and the proportion of women were higher than expected and bilateral active disease was lower than anticipated, highlighting that neither age nor gender should be overemphasized when diagnosing CSC. Therapeutic interventions are heterogeneous and include verteporfin photodynamic therapy, micropulse laser, and anti-VEGF injections in case of secondary CNV.

    Abstract: Clinical trials report substantial gains in visual acuity (VA) for eyes treated with intravitreal anti-VEGF for neovascular AMD (nAMD). In clinical reality, VA outcomes are more variable. Here we investigate pro-re nata treatment frequencies and VA in a real-life cohort of 1382 eyes (1048 patients). Patients with nAMD and one year complete follow-up treated with pro-re nata anti-VEGF between 2009 and 2016 were included. Injection frequency and VA was analyzed clustered by year of first treatment. Baseline parameters were compared between years. Median injection frequency in the first year was 5 with an IQR (interquartile range) of 5 for patients treated in 2009 and 8 with an IQR of 3 for patients treated from 2012 onwards. Median VA outcomes at one year were −5 to ±0 letters for patients treated between 2009 and 2013 and ±0 to +2 letters for patients treated from 2013 onwards. This cohort comprises all severities and subtypes of nAMD. 39% of patients had baseline VA outside the range for the MARINA or ANCHOR clinical trials. Higher treatment frequency was associated with improved VA in our real-life nAMD cohort. With adequate injection frequency, almost 90% of eyes had stable or improved VA over one year. Median VA gains, however, were lower compared to clinical trials. This may be due to a wider range of baseline characteristics in real-life cohorts.
