Abstract
Thrombosis of retinal veins is one of the most common retinal vascular diseases that may lead to vascular blindness. The latest epidemiological data leave no illusions that the burden on the healthcare system, as impacted by patients with this diagnosis, will increase worldwide. This obliges scientists to search for new therapeutic and diagnostic options. In the 21st century, there has been tremendous progress in retinal imaging techniques, which has facilitated a better understanding of the mechanisms related to the development of retinal vein occlusion (RVO) and its complications, and consequently has enabled the introduction of new treatment methods. Moreover, artificial intelligence (AI) is likely to assist in selecting the best treatment option for patients in the near future. The aim of this comprehensive review is to re-evaluate the old but still relevant data on the RVO and confront them with new studies. The paper will provide a detailed overview of diagnosis, current treatment, prevention, and future therapeutic possibilities regarding RVO, as well as clarifying the mechanism of macular edema in this disease entity.

Abstract
PURPOSE To investigate the association of retinal thickness 1 month after the first study aflibercept or bevacizumab injection with later retinal thickness, visual acuity, and number of treatments in eyes enrolled in the Study of COmparative Treatments for REtinal Vein Occlusion 2. DESIGN Cohort study using data from a randomized clinical trial. METHODS Analysis included one eye from each of 350 participants through 2 years of follow-up. Main outcome measures were central subfield thickness (CST), best-corrected visual acuity letter score (VALS), and number of treatments for macular edema. Retinas were classified as thin (≤216 µm), medium (>216 and ≤300 µm), or thick (>300 µm) based on CST. RESULTS At Month 1, 15% (51/350) of retinas were thin, 57% (199/350) were medium, and 29% (100/350) were thick. Of retinas that were thin at Month 1, 89% to 96% were thin during Months 2 to 12. Over all visits studied, the VALS of eyes with medium retinas at Month 1 was significantly greater than that of eyes with Month 1 thin retinas. During Months 6 to 12 (P < .001) and 12 to 24 (P < .001), the mean number of treatments was highest in eyes with thick retinas and lowest in eyes with thin retinas. Thin retinas had significantly more paracentral acute middle maculopathy and were more likely to have disorganization of the retinal inner layers inside the central subfield, and a history of anti-vascular endothelial growth factor treatment. CONCLUSIONS Having a post-treatment thin retina can be as detrimental to visual acuity as a post-treatment thick retina.

Abstract
Topic The goal of this review was to summarize the current level of evidence on biomarkers to quantify diabetic retinal neurodegeneration (DRN) and diabetic macular edema (DME). Clinical relevance With advances in retinal diagnostics, we have more data on patients with diabetes than ever before. However, the staging system for diabetic retinal disease is still based only on color fundus photographs and we do not have clear guidelines on how to incorporate data from the relatively newer modalities into clinical practice. Methods In this review, we use a Delphi process with experts to identify the most promising modalities to identify DRN and DME. These included microperimetry, full-field flash electroretinogram, spectral-domain OCT, adaptive optics, and OCT angiography. We then used a previously published method of determining the evidence level to complete detailed evidence grids for each modality. Results Our results showed that among the modalities evaluated, the level of evidence to quantify DRN and DME was highest for OCT (level 1) and lowest for adaptive optics (level 4). Conclusion For most of the modalities evaluated, prospective studies are needed to elucidate their role in the management and outcomes of diabetic retinal diseases.

Month 60 Imaging Findings and Relationship to Treatment Outcomes Following Anti-VEGF Therapy for Macular Edema Due to Central or Hemi-Retinal Vein Occlusion. Am J Ophthalmol 2024; 260:147-159. [PMID: 38061584 DOI: 10.1016/j.ajo.2023.11.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 11/22/2023] [Accepted: 11/27/2023] [Indexed: 01/21/2024]
Abstract
PURPOSE To evaluate imaging findings from SCORE2 participants through 60 months, to describe the degree of resolution or progression of these variables, and to correlate changes in these imaging findings to treatment outcomes such as visual acuity and the number of treatments administered. METHODS SCORE2 participants were followed for up to 60 months. Visual acuity, injection frequency and imaging tests color fundus photography (CFP), optical coherence tomography (OCT), and ultra-widefield fluorescein angiography [UWFA]) were performed throughout this period. RESULTS Less than 6% of eyes had subretinal fluid at month 60. Disorganization of the retinal inner layers (DRIL) was the most likely finding to persist, present in 96% of eyes at baseline and unchanged at 95% at month 60. For UWFA, at baseline, there was a mean of 5.0% non-perfusion area (95% CI: 3.3%-6.8%) in the NETWORC grid with little change to month 60. For the Early Treatment Diabetic Retinopathy Study (ETDRS) grid, at baseline, there was a mean of 2.3% non-perfusion area (95% CI: 0.7%-3.9%) with little change to month 60. There was no correlation between any of the imaging variables at baseline and change in visual acuity to month 60 or in the number of injections following the variable treatment timeframe (month 12 to month 60). CONCLUSIONS These analyses provide an anatomic explanation for persistent functional deficits many years following initial treatment. Clinical practice patterns should consider evaluation with these imaging tests to help explain persistent functional deficits in many eyes. Additionally, these 8 baseline imaging variables generally should not be relied on to predict visual acuity or intensity of treatment.

Abstract
PURPOSE To investigate the associations between visual acuity (VA) and structural optical coherence tomography (OCT) features in retinal vein occlusion (RVO) eyes after cystoid macular oedema (CMO) regression and to assess whether inner retinal thinning is progressive. METHODS Retrospective observational study of RVO eyes with regressed CMO for at least 6 months. OCT scans at CMO regression were analysed, and features were correlated with VA at that visit. The inner retinal thickness was longitudinally compared between RVO and unaffected fellow eyes (controls) with linear mixed models. The rate of inner retinal thinning was obtained as the interaction term between disease status and time. Associations between inner retinal thinning and clinical characteristics were explored. RESULTS Thirty-six RVO eyes were followed for 34.2 ± 21.1 months after CMO regression. The presence of ellipsoid zone disruption (regression estimate[standard error(SE)] = 0.16[0.04] LogMAR vs. intact, p < 0.001) and lower inner retinal thickness (regression estimate[SE] = -0.25[0.12] LogMAR for 100-μm increase, p = 0.01) were associated with worse VA. The inner retinal thickness decreased faster in RVO than controls (rate of retinal thinning -0.27 ± 0.09 μm/month vs. -0.08 ± 0.11 μm/month, p = 0.01). Macular ischaemia was associated with a faster rate of retinal thinning (interaction term macular ischaemia*follow-up time, p = 0.04). CONCLUSION Inner retinal and photoreceptors' layers integrity are associated with better visual acuity once CMO resolves. RVO eyes undergo progressive inner retinal thinning after CMO regression, faster in eyes with macular ischaemia.

Abstract
PURPOSE To determine whether macular infarction measured as hyper-reflectivity of the middle and inner retinal layers predicts long-term visual acuity outcomes in participants with central retinal vein occlusion (CRVO) or hemi-retinal vein occlusion (HRVO). DESIGN Clinical cohort study using post hoc secondary analysis of phase 3 clinical trial data. METHODS This post hoc secondary analysis of the phase 3 Study of COmparative Treatments for REtinal Vein Occlusions 2 (SCORE2) clinical trial included 310 of the 362 participants with macular edema secondary to CRVO/HRVO who were randomized to injections of aflibercept or bevacizumab. Month 01 (M01) optical coherence tomography (OCT) images were analyzed using the following grading scheme: no infarction (grade 0), only middle retinal infarction (grade 1), diffuse middle and patchy inner retinal infarction (grade 2), and diffuse middle and inner retinal infarction (grade 3). Visual acuity letter score (VALS), central subfield thickness (CST), and number of anti-vascular endothelial growth factor (anti-VEGF) injections were correlated with the infarction severity grade at month 01. RESULTS More severe macular infarction, with both middle and inner retinal layer hyper-reflectivity (ie, grades 2 and 3), was associated with worse M00 VALS and was predictive of VALS at M01 to M60 (P < .001). More severe infarction was associated with greater CST at presentation; however, after the first anti-VEGF injection, CST decreased and was similar across all grades at all time points (P > .05) with similar number of injections. CONCLUSIONS Participants with more severe macular infarction at M01, as graded with OCT, exhibited worse visual outcomes despite significantly improved macular edema from month 6 to 5 years. This suggests that macular infarction may drive visual acuity after retinal fluid is treated with anti-VEGF.

Abstract
PURPOSES To screen key indicators leading to unfavorable outcomes of retinal vein occlusion related macular edema (RVO-ME) within long-term follow-up duration and to evaluate their predictive values. METHODS A study involving patients with RVO-ME was conducted between April 2021 and September 2022. All eligible patients were divided into two groups (favorable and unfavorable group) according to their final best corrected visual acuity (BCVA) and whether neovascular glaucoma (NVG) occurred. The unfavorable group was further divided into subgroups 1 (with BCVA of ≥ 20/400 and < 20/60 and without NVG) and 2 (blindness group, with BCVA of < 20/400 or with NVG). Demographic, past medical history, ocular characteristics and blood parameters were compared between the groups. RESULTS A total of 73 eyes from 73 Chinese Han patients (34 males vs. 39 females) with RVO-ME were enrolled. In multivariable regression analysis of continuous variables for unfavorable results, 1-month BCVA after the first intravitreal injection (IVI) was an independent risk factor (odds ratios (ORs) = 2.313, 95% confidence interval (CI) 1.387-3.858, P = 0.001). The area under the curve (AUC) of 1-month BCVA after the first IVI for predicting low vision and blindness was 0.948 (95% CI 0.859-1.000, P < .001) and 0.892 (95% CI 0.744-1.000, P < .001), with a cut-off value of 0.65 logarithm of the minimum angle of resolution (log MAR) (Snellen 20/90) and 1.15 log MAR (Snellen 20/300), respectively. CONCLUSION The most valuable indicator for predicting low vision and blindness was poor 1-month BCVA after first IVI compared with favorable group.

Abstract
Purpose To assess the association of a novel spectral domain optical coherence tomography biomarker with 6-month visual acuity in in the Study of COmparative Treatments for REtinal Vein Occlusion 2. Methods Spectral domain optical coherence tomography volume scans were evaluated for inner retinal hyperreflectivity, quantified by optical intensity ratio (OIR) and OIR variation. Baseline visual acuity letter score (VALS), baseline OCT biomarkers, and month 1 OIR were correlated with VALS at month 6. Regression trees, a machine learning technique yielding readily interpretable models, were used to assess for variable interaction. Results Only baseline VALS correlated positively with month 6 VALS in multivariate regression. Regression trees detected a novel functional and anatomical interaction in a subgroup. Among patients with a baseline VALS worse than 43, those with an OIR variation at month 1 of more than 0.09 had a mean of 13 fewer letters of vision at 6 months compared with patients with an OIR variation of 0.09 or less. Conclusions Baseline VALS was the strongest predictor of month 6 VALS. Regression tree analysis detected an interaction effect, in which higher OIR variation at month 1 predicted worse 6-month VALS in patients with low VALS at baseline. OIR variation may serve as a predictor for poor visual outcome despite treatment of macular edema secondary to retinal vein occlusion in patients with poor vision at baseline. Translational Relevance Pixel heterogeneity in three-dimensional OCT data may serve as measure of disruption of the retinal laminations, and this factor may carry visually prognostic value.

Abstract
PURPOSE To evaluate the vision-related quality of life (VR-QOL) before and after intravitreal ranibizumab injections (IVR) for central retinal vein occlusion (CRVO) and to investigate subscale items of VR-QOL in detail. STUDY DESIGN A multicenter, open-label, prospective and comparative study. METHODS Twenty-three patients with treatment naïve CRVO and 22 age-matched normal controls were included. VR-QOL was assessed by 25-Item Visual Function Questionnaire (VFQ-25) before and up to 12 months post-treatment. The VFQ-25 composite score and 12 subscales were compared between CRVO patients and normal controls. RESULTS The VFQ-25 composite scores of CRVO patients showed significant improvement throughout the treatment period compared with baseline. The VFQ-25 composite scores both before and after treatment for CRVO were significantly lower than in normal controls. The subscale items, including general health, general vision, near activities, social functioning, mental health, role difficulties, dependency, and peripheral vision in CRVO, were significantly lower than in the normal controls even after treatment. CONCLUSION Vision-related QOL was low in patients with CRVO before treatment and improved with IVR. In spite of the improvements, several subscale items remained lower than in normal controls following treatment. Attention should be paid to the patients with CRVO and their decreased visual, social and psychological QOL.

Abstract
BACKGROUND Retinal vein occlusion, subdivided into central retinal and branch retinal vein occlusion, is one of the most frequent vascular diseases of the retina. Biomarkers of optical coherence tomography (OCT), OCT-angiography and (ultra-widefield) fluorescein angiography are of exceptional importance in the initial diagnosis and also in the treatment of complications associated with retinal vascular occlusion, particularly macular edema. METHODS A systematic literature review was carried out in PubMed with the keywords central retinal vein occlusion, branch retinal vein occlusion, biomarker, OCT, OCT angiography, ultra-widefield fluorescein angiography with prioritization of the most important aspects. RESULTS Relevant biomarkers in OCT include central retinal thickness (CRT), macular fluid, the integrity of the photoreceptor bands (external limiting membrane and ellipsoid zone), disorganization of retinal inner layers (DRIL), hyperreflective foci, choroidal thickness and signs of ischemia, such as a prominent middle limiting membrane (p-MLM), paracentral acute middle maculopathy (PAMM) as well as hyperreflectivity of inner retinal layers (HIRL). The importance of OCT-angiography lies particularly in the assessment of microvascular alterations, especially vessel density in the deep retinal vascular plexus, the foveal avascular zone and of areas with no capillary perfusion. Biomarkers of ultra-widefield angiography, such as peripheral ischemia (ischemic index) and neovascularízation are essential with respect to treatment decisions for retinal laser. CONCLUSION A multitude of simple and complex biomarkers currently enable an effective individualized evaluation of treatment and prognosis in retinal vein occlusion. A shift from invasive to noninvasive biomarkers can be observed.
