Purpose: To compare functional and anatomical outcomes between posterior drainage of residual fluid using a 41G cannula, fluid tolerance (residual subretinal fluid), and conventional complete drainage methods, including removal through peripheral retinal breaks, perfluorocarbon liquid, and posterior retinotomy., Methods: In this retrospective, multicenter study, we evaluated cases for visual acuity at 3 months of follow-up. Secondary outcomes included surgical success, postoperative metamorphopsia, shifts, full-thickness folds, optical coherence tomography parameters, and safety. Subgroup analyses were also conducted., Results: Visual acuity did not differ significantly between the three main groups. Subgroup analyses revealed worse visual acuity for posterior retinotomy (20/270 in Snellen conversion, P = 0.002), with significantly more Grade C proliferative vitreoretinopathy (40.0%, P = 0.003). Residual subretinal fluid tended to offer better secondary outcomes, without statistical significance except for postoperative epiretinal membrane (30.8%, P = 0.041). Subgroup analyses found significantly more shifts with PFCL (91.7%, P = 0.036). No cases of postoperative full-thickness folds or macular holes were observed with the 41G., Conclusion: Our study introduced the 41G technique, indicating favorable outcomes for fovea-off retinal detachments. Nevertheless, fluid tolerance appeared to be the best option, offering a cost-effective and faster method, with an optimal microstructural profile and visual acuity comparable with that of complete drainage techniques.

Purpose: Dexamethasone implant (DEX-implant) is one treatment choice in diabetic macular edema. However, steroid-induced cataract is a common complication when treating a chronic disease and could lead to vision loss. Because of the lack of studies specifically focused on the functional outcomes according to the lens status, the authors therefore aim to analyze the effectiveness and safety of DEX-implant treatment for diabetic macular edema in phakic versus pseudophakic eyes., Methods: This multicenter, retrospective study conducted in France included eyes of consecutive patients who had received a DEX-implant for diabetic macular edema., Results: A total of 328 eyes were included: 158 eyes (48.2%) were phakic, 167 eyes (50.9%) were pseudophakic and three were unknown. According to the lens status, mean change in best-corrected visual acuity from baseline was never significantly different between phakic and pseudophakic eyes (likelihood ratio test, P = 0.09) nor in the change in central macular thickness (likelihood ratio test, P = 0.79) in multivariate analysis. Cataract surgery was performed in 63 phakic eyes (39.9%) during the study period with a mean delay of 8.1 months (CI95% [6.59-9.69]). The mean change in best-corrected visual acuity between phakic eyes who underwent cataract surgery and those who did not, was not significantly different during the follow-up at each visit. The risk of ocular hypertension was not statistically different between phakic and pseudophakic subsets ( P = 0.9)., Conclusion: The authors showed here that phakic eyes treated with DEX-implant for diabetic macular edema did not have a significant difference in visual gain in comparison to pseudophakic eyes, with a comparable safety profile., Competing Interests: T.

Purpose: To determine the preoperative factors influencing visual recovery after vitrectomy for myopic foveoschisis., Methods: Sixty-six eyes of 65 consecutive patients operated on for myopic foveoschisis were retrospectively included. All eyes underwent a preoperative ocular examination including best-corrected visual acuity (BCVA) and spectral domain optical coherence tomography with central foveal thickness measurement and foveal status classification: simple foveoschisis, foveal detachment, or macular hole. To study the impact of preoperative visual acuity, 4 visual acuity groups separated by quartile ranges were defined. Postoperative visits at 1, 3, or 12 months including BCVA measurement and optical coherence tomography were recorded., Results: Mean refraction was -15.90 diopters, mean axial length was 30.30 mm, mean central foveal thickness was 590 μm, and mean baseline logarithm of the maximum angle of resolution visual acuity was 0.68 (Snellen equivalent of 20/96). The final BCVA improved significantly from 3 months after surgery until the last follow-up visit; the mean logarithm of the maximum angle of resolution visual acuity at last follow-up was 0.43 (Snellen equivalent of 20/54). Mean central foveal thickness decreased significantly as soon as the first postoperative month (P < 0.0001). The preoperative BCVA was the only independent factor significantly correlated with the final BCVA as opposed to the foveal status (P < 0.0001). The mean BCVA and mean visual gain at the last follow-up visit were significantly different between the four visual acuity groups (P < 0.0001 and P = 0.017, respectively)., Conclusion: The main factor influencing the postoperative visual acuity is the preoperative visual acuity. Although the preoperative anatomical status seemed important in surgeon decision making, once normalized on visual acuity, it no longer influenced the postoperative visual acuity.
