Abstract
To compare baseline characteristics, initial response and 12-month efficacy and safety outcomes in eyes with branch and central retinal vein occlusion (BRVO and CRVO) treated with dexamethasone implants (DEX) or anti-vascular endothelial growth factor (anti-VEGF) we performed a multi-centre, retrospective and observational study using Fight Retinal Blindness! Registry. Of 725 eligible eyes, 10% received DEX initially with very frequent adjunctive anti-VEGF (BRVO-DEX 49%, CRVO-DEX 60%). The primary outcome of mean adjusted change in VA at 12 months with DEX and anti-VEGF initiated groups were not statistically significantly different (BRVO: DEX + 6.7, anti-VEGF + 10.6 letters; CRVO: DEX + 2.8, anti-VEGF + 6.8 letters). DEX initiated eyes had fewer injections and visits than anti-VEGF initiated eyes. The BRVO-DEX eyes had greater initial mean changes in VA and central subfield thickness (CST) and achieved inactivity sooner than BRVO-anti-VEGF eyes. The mean CST after the first three months was above 350 μm in all but the BRVO-anti-VEGF group, suggesting undertreatment. In routine care DEX is uncommonly used when available as initial treatment of BRVO and CRVO requiring supplemental anti-VEGF within the first year. The 12-month outcomes were similar, but DEX initiated eyes had fewer injections and visits but more episodes of raised IOP Vs those starting anti-VEGF.

Alterations in Retinal Vessel Diameters in Patients with Retinal Vein Occlusion before and after Treatment with Intravitreal Ranibizumab. J Pers Med 2023; 13:jpm13020351. [PMID: 36836585 PMCID: PMC9963538 DOI: 10.3390/jpm13020351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 02/09/2023] [Accepted: 02/16/2023] [Indexed: 02/19/2023] Open
Abstract
Purpose: To investigate the alterations of retinal vessel diameters in patients with macular edema secondary to retinal vein occlusion (RVO), before and after treatment with intravitreal ranibizumab. Methods: Digital retinal images were obtained from 16 patients and retinal vessel diameters were measured before and three months after treatment with intravitreal ranibizumab with validated software to determine central retinal arteriolar and venular equivalents, as well as arteriolar to venular ratio. Results: In 17 eyes of 16 patients with macular edema secondary to RVO (10 with branch RVO and 6 with central RVO) aged 67 ± 10.2 years, we found that diameters of both retinal arterioles and venules were significantly decreased after intravitreal ranibizumab treatment. Specifically, the central retinal arteriolar equivalent was 215.2 ± 11.2 μm at baseline and 201.2 ± 11.1 μm at month 3 after treatment (p < 0.001), while the central retinal venular equivalent was 233.8 ± 29.6 μm before treatment versus 207.6 ± 21.7 μm at month 3 after treatment (p < 0.001). Conclusions: A significant vasoconstriction in both retinal arterioles and venules in patients with RVO was found at month 3 after intravitreal ranibizumab treatment compared to baseline. This could be of clinical importance, since the degree of vasoconstriction might be an early marker of treatment efficacy, compatible with the idea that hypoxia is the major trigger of VEGF in RVO. Further studies should be conducted to confirm our findings.

Abstract
Objective To evaluate the safety and tolerability of a mineralocorticoid, in a single-dose intravitreal (IVT) injection of 1 mg/0.1 mL and 2 mg/0.1 mL fludrocortisone acetate (FCA) in subjects with geographical atrophy (GA) secondary to age-related macular degeneration. Methods and Analysis This phase 1b study was a two-part dose-escalation prospective study. Part 1 involved a single participant treated with 1 mg/0.1 mL and monitored up to 28 days before being reviewed by a safety review committee. Two subsequent participants were then dosed with the same dose. Part 2 involved a single participant dosed with 2 mg/0.1 mL and monitored up to 28 days when a further five participants were dosed. All participants were followed up for 6 months after baseline. A full ophthalmic assessment was performed at study visits which included GA area, best-corrected visual acuity (BCVA), low-luminance BCVA (LL-BCVA) and intraocular pressure (IOP). Adverse events (AEs) were reported from the first dose of FCA until the end-of-study visit. Results There were no serious AEs (ocular or systemic) observed with IVT FCA at either 1 mg/0.1 mL or 2 mg/0.1 mL among nine participants. There was no evidence of increased IOP or cataract development. Neither BCVA or LL-BCVA changed significantly in the study-eye over the follow-up period (p=0.28 and 0.38, respectively). Mean GA area increased in the study (0.5 mm2, p=0.003) and fellow-eyes (0.62 mm2, p=0.02) over 6 months. Differences between eyes were not significant (p=0.64), and at the lower end of population norms. Conclusion IVT FCA is clinically safe and well tolerated and did not increase IOP.

The impact of laboratory findings and optical coherence tomography biomarkers on response to intravitreal anti-VEGF treatment in patients with retinal vein occlusion. Int Ophthalmol 2022; 42:3449-3457.

Abstract
AIMS To investigate potential laboratory and imaging biomarkers as treatment response predictors to intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents in patients with retinal vein occlusion (RVO). METHODS Participants in this prospective study were 53 patients with treatment naïve macular edema secondary to RVO, treated with intravitreal anti-VEGF agents and followed-up for 12 months. At baseline, all participants underwent best-corrected visual acuity measurement, dilated fundoscopy, optical coherence tomography and fluorescein angiography (FFA), while full blood count and biochemical analysis of various parameters was also performed. At month 12, treatment response was examined and classified as "favorable" or "non-response". Potential associations between laboratory/imaging biomarkers and treatment response were assessed. RESULTS Univariate analysis showed that "favorable" response at month 12 after initiation of anti-VEGF treatment was correlated with baseline central subfield thickness (CST) < 464 μm (p < 0.001), absence of subretinal fluid (p = 0.004), absence of hyperreflective foci (HF) (p = 0.004), intact ellipsoid zone (EZ) and external limiting membrane (ELM) (p < 0.001 and p = 0.001, respectively), absence of epiretinal membrane (ERM) (p = 0.020) and absence of macular ischemia on FFA (p < 0.001), while increased monocytes-to-lymphocytes ratio was also associated with "favorable" treatment response (p = 0.010). All other laboratory parameters did not reach statistical significance. However, at the multivariate analysis, EZ and ELM status, HF, macular ischemia and monocytes-to-lymphocytes ratio were found to be independent predictors of treatment response. CONCLUSIONS Intact EZ and ELM, absence of HF, absence of macular ischemia and increased monocytes-to-lymphocytes ratio at baseline can predict "favorable" treatment response in patients with treatment naïve macular edema secondary to RVO.

Intravitreal Administration Effect of Adipose-Derived Mesenchymal Stromal Cells Combined with Anti-VEGF Nanocarriers, in a Pharmaceutically Induced Animal Model of Retinal Vein Occlusion. Stem Cells Int 2022; 2022:2760147.

Abstract
Antiangiogenic therapeutic agents (anti-VEGF) have contributed to the treatment of retinal vein occlusion (RVO) while mesenchymal stromal cell- (MSCs-) mediated therapies limit eye degeneration. The aim of the present study is to determine the effect of adipose-derived MSCs (ASCs) combination with nanocarriers of anti-VEGF in a pharmaceutically induced animal model of RVO. Nanoparticles (NPs) of thiolated chitosan (ThioCHI) with encapsulated anti-VEGF antibody were prepared. ASCs were isolated and genetically modified to secrete the green fluorescence GFP. Twenty-four New Zealand rabbits were divided into the I-IV equal following groups: ASCs, ASCs + nanoThioCHI-anti-VEGF, RVO, and control. For the RVO induction, groups I-III received intravitreal (iv) injections of MEK kinase inhibitor, PD0325901. Twelve days later, therapeutic regiments were administered at groups I-II while groups III-IV received BSS. Two weeks later, the retinal damage evaluated via detailed ophthalmic examinations, histological analysis of fixed retinal sections, ELISA for secreted cytokines in peripheral blood or vitreous fluid, and Q-PCR for the expression of related to the occlusion and inflammatory genes. Mild retinal edema and hemorrhages, limited retinal detachment, and vasculature attenuation were observed in groups I and II compared with the pathological symptoms of group III which presented a totally disorganized retinal structure, following of positive immunostaining for neovascularization and related to RVO markers. Important reduction of the high secreted levels of inflammatory cytokines was quantified in groups I and II vitreous fluid, while the expression of the RVO-related and inflammatory genes has been significantly decreased especially in group II. GFP+ ASCs, capable of being differentiated towards neural progenitors, detected in dissociated retina tissues of group II presenting their attachment to damaged area. Conclusively, a stem cell-based therapy for RVO is proposed, accompanied by sustained release of anti-VEGF, in order to combine the paracrine action of ASCs and the progressive reduction of neovascularization.

Abstract
Purpose: The purpose of this study was to evaluate health-related quality of life in patients with retinal vein occlusion (RVO) and investigate the possible risk factors for poor quality of life in patients with RVO.Methods: Participants in the study were 67 patients with RVO, 42 male and 25 female, mean-aged 73.1 ± 10.9 years, and 70 sex- and age-matched controls. Demographic data, lifestyle factors and medical history were recorded. All patients underwent best-corrected visual acuity measurement, dilated fundoscopy and optical coherence tomography. All participants completed two questionnaires assessing quality of life (EQ-5D, NEI VFQ-25). Risk factors for health-related quality of life in RVO patients were investigated.Results: Patients with RVO exhibited significantly lower composite score for VFQ-25 compared to controls (74.1 ± 3.8 vs. 91.7 ± 3.9 for patients and controls, respectively, p < .001). In addition, RVO patients had significantly lower EQ-5D Index score compared to controls (0.88 ± 0.15 vs. 0.92 ± 0.12 for patients and controls, respectively, p = .043). Risk factors associated with quality of life in patients with RVO were found the alcohol consumption, the presence of thyroidopathy, coagulation disorders, visual acuity in the eye with RVO, central retinal thickness, the type of edema, the presence of ischemia and the condition of external limiting membrane. In multivariate analysis, only alcohol consumption and visual acuity in the eye with RVO were found to be independent risk factors, affecting quality of life in RVO patients.Conclusions: Patients with RVO presented lower quality of life in comparison with controls. Potential risk factors should be taken into account and their early detection may improve quality of life in such patients and lead to targeted health policies.

Abstract
Ophthalmic disease encountered in the intensive care unit (ICU) has a wide spectrum of prevalence and severity. Prolonged exposure of the cornea is common and preventable. Trauma, glaucoma, infection, vascular disease, and burns are among the potential causes of vision loss. Patients are predisposed to ocular complications by the ICU environment and critical illness itself. Critically ill patients require prioritization of life-sustaining interventions, and less emphasis is placed on ophthalmic disease, leading to missed opportunities for vision-saving intervention. It is therefore imperative for intensivists, nurses, and other providers to have an increased awareness and understanding of the broad range of ocular conditions potentially seen in the ICU.

Abstract
The intravitreal (IVT) injection method is a choice when targeting the inner retina for gene therapy. However, the transduction efficiency of adeno-associated virus (AAV) vectors administered by the IVT route is usually low and may be affected by several factors. To improve the transduction efficiency, we developed a novel illuminated long-needle attached injection system and injected AAV2-CMV (cytomegalovirus)-EGFP in front of the retina in rabbit eyes. Ophthalmological examinations were performed and the levels of pro-inflammatory cytokines in the aqueous humor were assessed at the baseline and 1 month, and the results were compared with those of the conventional injection method. Retinal tissues were used for immunohistochemistry. In the ophthalmological examinations, no significant inflammatory signs were detected in both groups, except for transient, mild hyperemia. In the tissues of the rabbits in the peripapillary injection group, significantly increased GFP expression was detected at the ganglion cell and the inner nuclear layers (p < 0.01). There were no differences between groups in glial activation and expressions of interleukin (IL)-6 and IL-8. These results suggest that peripapillary IVT injection in front of the retina would be safe and efficiently transduce viral vectors into the retina of large animals and is considered as a potential method for use in clinical trials.

Abstract
PURPOSE The purpose of this meta-analysis was to compare the efficacy and safety of corticosteroid implant and intravitreal ranibizumab for the treatment of macular edema (ME). MATERIALS AND METHODS PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials were comprehensively searched for studies comparing dexamethasone implant with ranibizumab in patients with ME. Best-corrected visual acuity (BCVA), central subfield thickness (CST), and adverse events were extracted from the final eligible studies. RevMan 5.3 software was used to analyze the data, and the modified Jadad assessment tool was used to access the quality of outcomes. RESULTS Three randomized controlled trials (RCTs) were included in our analysis. The types of causes of ME include central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), and diabetic retinopathy (DR). The ranibizumab treatment group had significantly better BCVA compared with the corticosteroid treatment group (standard mean difference [SMD] -0.80; 95% CI -1.08, -0.53; P<0.00001). The ranibizumab treatment group also had higher CST reduction compared with the corticosteroid treatment group, and there was a significant difference (weighted mean difference [WMD] 167.58; 95% CI 125.21-209.95; P<0.00001). There was no significant difference in serious adverse effects between the two groups (SMD 1.67; 95% CI 0.69, 4.05; P=0.26). However, the use of corticosteroid implant had a higher risk of intraocular pressure (IOP) (OR 6.88; 95% CI 4.53-10.44; P<0.00001) elevation and cataract (OR 3.98; 95% CI 1.89-8.37; P=0.0003) than ranibizumab treatment and fewer injections. CONCLUSIONS Compared with ranibizumab, corticosteroid implant did not have greater improved BCVA, but corticosteroid implant had less CST reduction. The advantages of corticosteroids are fewer injections, while the advantages of ranibizumab include fewer side effects.

Abstract
PURPOSE To compare intravitreal ranibizumab and dexamethasone implant in patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO). METHODS Participants were 42 treatment naive patients with ME due to CRVO, who received either intravitreal 0.5 mg ranibizumab (n = 25) or intravitreal 0.7 mg dexamethasone implant (n = 17). The main outcomes included the mean change in best corrected visual acuity (BCVA) and central subfield thickness (CST) at month 12 compared to baseline in the two groups. RESULTS At month 12, there was no statistically significant difference in BCVA and CST change between the two groups. However, there was recurrence in ME at month 5 in the dexamethasone group. CONCLUSIONS Both ranibizumab and dexamethasone implant were found to be safe and effective at the 12-month follow-up in patients with ME secondary to CRVO. Since there was a recurrence in ME at month 5 in the dexamethasone group, we suggested that intravitreal injection of dexamethasone implant should be potentially administered sooner than 6 months.

Abstract
Background One limitation of anti-VEGF therapy is the need for monthly retreatment to maintain efficacy. The purpose of this study was to determine the duration of effect in eyes with macular edema (ME) secondary to branch or central retinal vein occlusion (BRVO or CRVO) treated with anti-VEGF therapy plus sustained-release dexamethasone (DEX implant; Ozurdex). Materials and methods This open-label, interventional case series included 62 eyes with ME due to RVO, central foveal thickness (CFT) >300 μm, and best-corrected visual acuity (BCVA) of 20/40 or worse. Each treatment cycle included an anti-VEGF injection followed 2 weeks later with DEX implant. Patients were eligible for retreatment if CFT increased to >290 μm or increased by >50 μm from the lowest measurement, or if BCVA decreased by six or more Snellen letters. Efficacy and safety were evaluated 2 and 4–6 weeks after the beginning of each treatment cycle and every 4 weeks thereafter until retreatment criteria were met. The primary outcome measure was time to retreatment. Secondary outcome measures included BCVA, CFT, and safety parameters. Results The mean reinjection interval for all patients was 135.5±36.4 days. There was no statistically significant difference in mean intertreatment interval for up to six cycles of treatment or between eyes with BRVO or CRVO (P≥0.058). Mean peak change in BCVA was 13.8 letters, and 47.6% of eyes gained three or more lines of BCVA. The mean peak decrease in CFT across all treatment cycles was 200.9 μm for eyes with BRVO and 219.2 μm for eyes with CRVO. The percentage of patients with CFT ≤300 μm at any time during a given treatment cycle ranged from 78% to 94% among eyes with BRVO and from 85% to 100% among eyes with CRVO. Intraocular pressure increased in 19 of 62 eyes, and 26 of 44 phakic eyes underwent cataract surgery. Conclusion In eyes with ME due to RVO, treatment with an anti-VEGF agent plus DEX implant provided a predictable duration of effect, as well as significant improvements in BCVA and CFT.
