To compare intravitreal bevacizumab monotherapy with intravitreal dexamethasone delayed delivery system monotherapy for persistent diabetic macular edema. Single-center, randomized, subject-masked study of eyes with persistent diabetic macular edema, defined as central subfield thickness (CST) >340 μm despite ≥3 anti–vascular endothelial growth factors injections within 5 months. The intravitreal bevacizumab monotherapy (n = 23 eyes) and delayed delivery system monotherapy (n = 27 eyes) groups received treatments q1month and q3months, respectively. Baseline best-corrected visual acuity and CST were similar in the two groups. At Month 7, the mean final best-corrected visual acuity (mean ± SD) was 65 ± 16 letters (mean Snellen visual acuity 20/50) and 64 ± 11 letters (20/50) (P = 0.619), the mean change in best-corrected visual acuity was +5.6 ± 6.1 and +5.8 ± 7.6 letters (P = 0.785), the mean final CST was 471 ± 157 and 336 ± 89 μm (P = 0.001), and the mean change in CST was −13 ± 105 and −122 ± 120 μm (P = 0.005) in the intravitreal bevacizumab monotherapy and delayed delivery system monotherapy groups, respectively. The number of injections was 7.0 ± 0.2 and 2.7 ± 0.5 (P < 0.001) in the 2 groups. The two groups had similar best-corrected visual acuity gains. The delayed delivery system monotherapy group achieved a significantly greater reduction of CST compared with the intravitreal bevacizumab monotherapy group, with a q3month interval of treatment, and had no recurrent edema at any visit.

To evaluate morphologic features and the evolution of inner retinal dimples using spectral domain optical coherence tomography after internal limiting membrane peeling.A single-center retrospective study of spectral domain optical coherence tomography features in 43 eyes after full-thickness macular hole surgery with internal limiting membrane peeling without adjunctive internal limiting membrane staining.Postoperatively, a total of 210 dimples were noted in 37 eyes (86%), with a mean of 5.7 dimples per eye (median, 5; range, 1-20), most frequently located in the inferotemporal quadrant (n = 122, 58%, P0.0001). At initial detection, mean dimple dimensions were 199 μm wide (median, 183; range, 87-442 μm) and 19 μm deep (median, 17; range, 7-35 μm). During follow-up, mean maximum dimensions were 351 μm wide (median, 305; range, 219-494 μm) and 30 μm deep (median, 31; range, 15-55 μm). Dimple dimension reached a maximum at 12 months (median, 10; range, 2-22 months) followed by a modest decline. Mean preoperative and final postoperative visual acuity were 0.70 logMAR (median, 0.54; range, 0.09-1.4 logMAR) and 0.38 logMAR (median, 0.30; range, 0-1.4 logMAR), respectively.Inner retinal dimples are common after adjunct-free internal limiting membrane peeling and evolve in the postoperative period with enlargement over the first 12 months followed by reduction in size, and have no apparent impact on the visual acuity.

PURPOSE To assess the overall risk of needlestick injuries (NSIs) associated with intravitreal injection, and more specifically related to the practice of compounding pharmacies of applying informational adhesive stickers to repackaged bevacizumab injection syringes. METHODS This cross-sectional study involved an online survey of retina specialists in the United States. RESULTS Of the 717 invited retina specialists, 158 (22%) responded to the online survey. The respondents reported using 1 pair of gloves (51%), no gloves (46%), or 2 pairs of gloves (3%) during intravitreal injection. Repackaged bevacizumab syringes distributed by compounding pharmacy were used by 89% of the respondents, and 63% reported that the adhesive sticker was applied directly to the syringe. Unintentional adhesion between the sticker and hand or glove was experienced by 9% of respondents. At least 1 NSI during intravitreal injection was experienced by 8% of respondents, and sticker-related injury was reported by 3%. The sticker was perceived to increase risk for NSI by 33% of respondents. CONCLUSION This survey showed that 8% of the responding physicians surveyed have experienced at least one NSI during intravitreal injections, of which approximately one third was attributed to the adhesive sticker. Direct application of misfitting stickers to repackaged syringes by compounding pharmacies may be a practice that can aggravate the risk of NSI.

PURPOSE: To study the effect of intraarterial chemotherapy (IAC) on retinoblastoma-induced retinal detachment. METHODS: Retrospective, noncomparative, interventional case series including 15 patients, with intraarterial (ophthalmic artery) chemotherapy as the intervention. Resolution of retinal detachment was the main outcome measure. RESULTS: Of 15 patients with retinoblastoma-induced retinal detachment managed with IAC, 7 (47%) presented with total retinal detachment and 8 (53%) with partial detachment. The eyes were classified as International Classification of Retinoblastoma group C (n = 2, 13%), group D (n = 4, 27%), and group E (n = 5, 33%). There were 4 eyes (27%) that received IAC as secondary treatment after the failure of other treatment methods. After IAC, all tumors showed regression. Of the 7 eyes with initial total retinal detachment, complete resolution of fluid was found in 3 (43%) and partial resolution in 4 (57%). Of the 8 eyes with initial partial retinal detachment, complete resolution of subretinal fluid was found in all 8 (100%), but 1 eye later developed recurrent subretinal fluid. The mean interval to complete resolution of subretinal fluid was 2 months. Globe salvage was achieved in 5 of 7 eyes (71%) with total retinal detachment and 6 of 8 eyes (75%) with partial retinal detachment. CONCLUSION: Eyes with retinoblastoma-induced total or partial retinal detachment showed complete resolution of detachment after IAC in 43% and 100%, respectively.
