One-Year Anti-VEGF Therapy Outcomes in Diabetic Macular Edema Based on Treatment Intensity: Data from the Fight Retinal Blindness! Registry.

PURPOSE: To compare 1-year outcomes of eyes with diabetic macular edema (DME) treated in routine clinical practice based on the proportion of visits where intravitreal VEGF inhibitor injections were delivered. DESIGN: Cohort study. PARTICIPANTS: There were 2288 treatment-naive eyes with DME starting intravitreal VEGF inhibitor therapy from October 31, 2015 to October 31, 2021 from the Fight Retinal Blindness! international outcomes registry. METHODS: Eyes were grouped according to the proportion of visits at which an injection was received, Group A with less than the median of 67% (n = 1172) versus Group B with greater than the median (n = 1116). MAIN OUTCOME MEASURES: Mean visual acuity (VA) change after 12 months of treatment. RESULTS: The mean (95% confidence interval [CI]) VA change after 12 months of treatment was 3.6 (2.8-4.4) letters for eyes in Group A versus 5.2 (4.4-5.9) letters for eyes in Group B (P = 0.005). The mean (95% CI) central subfield thickness (CST) change was -69 (-76 to -61) µm and -85 (-92 to -78) µm for eyes in Group A versus Group B, respectively (P = 0.002). A moderate positive correlation was observed between the number of injections received over 12 months of treatment and the change in VA (P < 0.001). Additionally, eyes that received more injections had a moderately greater CST reduction. CONCLUSIONS: This registry analysis found that overall VA and anatomic outcomes tended to be better in DME eyes treated at a greater proportion of visits in the first year of intravitreal VEGF inhibitor therapy.

Initial response and 12-month outcomes after commencing dexamethasone or vascular endothelial growth factor inhibitors for retinal vein occlusion in the FRB registry.

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.

OUTCOMES OF SWITCHING FROM PROACTIVE TO REACTIVE TREATMENT AFTER DEVELOPING ADVANCED CENTRAL NEOVASCULAR AGE-RELATED MACULAR DEGENERATION.

PURPOSE: We assessed outcomes of eyes with neovascular age-related macular degeneration (nAMD) that switched from proactive (treat-and-extend) to reactive (pro re nata) treatment regimen after developing macular atrophy (MA) or submacular fibrosis (SMFi). METHODS: Data were collected from a retrospective analysis of a prospectively designed, multinational registry of "real-world" nAMD treatment outcomes. Eyes without MA or SMFi when starting treatment with a vascular endothelial growth factor inhibitor regimen that subsequently developed MA or SMFi were included. RESULTS: Macular atrophy developed in 821 eyes and SMFi in 1,166 eyes. Seven percent of eyes that developed MA and 9% of those that developed SMFi were switched to reactive treatment. Vision was stable at 12 months for all eyes with MA and inactive SMFi. Active SMFi eyes that switched to reactive treatment had significant vision loss. No eyes that continued proactive treatment developed ≥15 letter loss, but 8% of all eyes that switched to a reactive regimen and 15% of active SMFi eyes did. CONCLUSION: Eyes that switch from proactive to reactive treatment after developing MA and inactive SMFi can have stable visual outcomes. Physicians should be aware of the risk of a significant loss of vision in eyes with active SMFi that switch to reactive treatment.

SUCCESSFUL CLOSURE OF A LARGE FULL-THICKNESS MACULAR HOLE SECONDARY TO AN IDIOPATHIC RETINAL VASOPROLIFERATIVE TUMOR USING THE INVERTED INTERNAL LIMITING MEMBRANE FLAP TECHNIQUE.

PURPOSE: To report a case of large full thickness macular hole (MH) as an uncommon complication of an idiopathic retinal vasoproliferative tumor (RPVT) and the successful closure of the full-thickness MH by the inverted internal limiting membrane Flap technique. METHODS: A case report. A 40-year-old woman was referred for a progressive and profound visual loss on the right eye. The fundus examination showed a full-thickness MH and the presence of an idiopathic RPVT surrounding by numerous exudates in the inferior temporal of the peripheral retina. In addition, the spectral domain optical coherence tomography imaging confirmed the large size of the full-thickness MH (740 µ m-diameter). First, we treated the RPVT using the transconjunctival cryotherapy. Then, we performed the macular surgery including 25 Gauge vitrectomy, inverted internal limiting membrane flap technique, and gas tamponade. RESULTS: In the postoperative period, the RPVT remained inactive with no recurrence of the MH or excessive gliosis proliferation on the internal limiting membrane flap area. Moreover, visual acuity rose up from 20/100 (0.2) at 1-month follow-up to 20/40 (0.5) at 6-month follow-up. CONCLUSION: In our patient, the full-thickness MH was precisely large and secondary to an RPVT. The treatment of the tumor by transconjunctival cryotherapy had been efficient and the postoperative follow-up after the macular procedure involving the inverted internal limiting membrane flap technique showed the anatomical and functional recovery of the macula.

High prevalence of PRPH2 in autosomal dominant retinitis pigmentosa in france and characterization of biochemical and clinical features.

PURPOSE: To assess the prevalence of PRPH2 in autosomal dominant retinitis pigmentosa (adRP), to report 6 novel mutations, to characterize the biochemical features of a recurrent novel mutation, and to study the clinical features of adRP patients. DESIGN: Retrospective clinical and molecular genetic study. METHODS: Clinical investigations included visual field testing, fundus examination, high-resolution spectral-domain optical coherence tomography (OCT), fundus autofluorescence imaging, and electroretinogram (ERG) recording. PRPH2 was screened by Sanger sequencing in a cohort of 310 French families with adRP. Peripherin-2 protein was produced in yeast and analyzed by Western blot. RESULTS: We identified 15 mutations, including 6 novel and 9 previously reported changes in 32 families, accounting for a prevalence of 10.3% in this adRP population. We showed that a new recurrent p.Leu254Gln mutation leads to protein aggregation, suggesting abnormal folding. The clinical severity of the disease in examined patients was moderate with 78% of the eyes having 1-0.5 of visual acuity and 52% of the eyes retaining more than 50% of the visual field. Some patients characteristically showed vitelliform deposits or macular involvement. In some families, pericentral RP or macular dystrophy were found in family members while widespread RP was present in other members of the same families. CONCLUSIONS: The mutations in PRPH2 account for 10.3% of adRP in the French population, which is higher than previously reported (0%-8%) This makes PRPH2 the second most frequent adRP gene after RHO in our series. PRPH2 mutations cause highly variable phenotypes and moderate forms of adRP, including mild cases, which could be underdiagnosed.
