The preoperative presence of detectable ellipsoid layers and a lower height of SMH may predict good visual prognosis. In contrast, no specific features of pigment epithelial detachment correlated with postoperative best-corrected visual acuity.

The better VA in the initial ranibizumab group compared with the PDT group at 2 years was retained at the 5-year follow-up.

Purpose. To evaluate the influences of 27-gauge vitrectomy on corneal topographic conditions. Method. Fifty-six eyes of 56 patients undergoing 27-gauge vitrectomy were retrospectively studied. Twenty-three eyes with epiretinal membrane (ERM), 23 eyes with macular hole (MH), and 10 eyes with proliferative diabetic retinopathy (PDR) were included. Forty-five of the 56 eyes underwent 27-gauge phacovitrectomy (group 1), and the remaining 11 eyes underwent 27-gauge vitrectomy alone (group 2). Corneal topography was obtained with a wave-front analyzer preoperatively and at 1 and 3 months postoperatively. The corneal topographic parameters evaluated were the average corneal power, regular astigmatism, spherical aberration, and higher-order aberration (HOA). Results. In between-group analyses of groups 1 and 2, no significant differences were observed regarding the changes of the 4 parameters from the baseline to 1 and 3 months postoperatively. No significant differences in the changes of all parameters from the baseline to 1 and 3 months postoperatively were also observed between MH group and the other two groups. A significant difference in the change of HOA from the baseline to 1 month postoperatively was observed between ERM and PDR group however, the difference disappeared at 3 months. Conclusion. 27-gauge vitrectomy did not induce substantial changes in the corneal topographic conditions.

Background. To evaluate the efficacy of intravitreal bevacizumab (IVB) injection with or without macular laser photocoagulation (MLP) for recurrent or persistent macular edema (ME) secondary to branch retinal vein occlusion (BRVO). Methods. Thirty-four eyes underwent IVB injection for ME secondary to BRVO as a primary treatment. Twenty of the 34 eyes experienced recurrent or persistent ME after the first IVB. Nine of the 20 eyes (Group 1) were retreated with IVB combined with MLP. The remaining 11 eyes (Group 2) were retreated with IVB alone. Results. In Group 1, the postoperative best corrected visual acuity (BCVA) improved compared with the preoperative value at all follow-up visits, although no statistically significant improvement was observed at 6 months. In contrast, BCVA significantly improved from 0.53 to 0.40 at 6 months (P < 0.05) in Group 2. Conclusion. Combined therapy tended to have a smaller effect on visual acuity compared with IVB monotherapy.

PurposeThis paper reports a young patient with a traumatic rhegmatogenous retinal detachment and massive vitreous gel incarceration into the subretinal space, who was successfully treated with 23-gauge transconjunctival vitrectomy.Case reportAn 11-year-old boy was referred to the authors’ clinic with traumatic retinal detachment in the right eye, 2 weeks after ocular contusion in a baseball accident. At the time of the injury, emergency fundus examination by his local doctor had revealed vitreous hemorrhage in the inferior quadrant of the right eye. Visual acuity was 1.5. He had continued to play baseball as usual for 2 weeks after the injury. At his first visit to the authors’ clinic, fundus examination showed a highly bullous retinal detachment involving the inferior two quadrants, associated with multiple irregular retinal breaks. There was an oval hole in the inferior quadrant which was 10-disc diameter × 5-disc diameter in size and was surrounded by edematous and hemorrhagic retina. The macula remained attached. Absolute rest for 4 hours in the supine position with binocular occlusion did not diminish the height of the retinal detachment. A 23-gauge three-port pars plana vitrectomy combined with 360° circumferential buckling was performed under general anesthesia. The lens was retained. Incarceration of massive vitreous gel, including vitreous hemorrhage into the subretinal space through the largest break, was observed during vitrectomy. Reattachment of the retina was achieved by fluid–air exchange and internal tamponade using SF6 gas. At follow-up at 9 months, the retina remained attached and visual acuity in the right eye was 1.2.
