Objective: To characterize 20 cases of retinal detachment (RD) following surgical repair of macular holes., Methods: Retrospective review of 20 eyes in 16 patients (4 patients [25%] had bilateral macular hole repairs with subsequent RD) who developed RD in the same eye in which surgical repair of a macular hole had been performed., Results: Twenty detachments in 16 patients were reviewed. The average duration between macular hole repair and presentation of RD was 5.5 weeks. The inferior retina was involved more frequently than the superior retina. A total of 76% of all breaks were located inferiorly. Ten of the 20 eyes were asymptomatic at the time the detachment was diagnosed. Of the 20 eyes, 19 underwent surgical repair, all with anatomic reattachment. At final follow-up, the macular hole was closed in all 20 eyes, and 60% of the patients had final visual acuity improved by 2 lines or more over that before their macular hole repair., Conclusion: Retinal detachment is a complication of macular hole surgery. These detachments tend to occur within the first 2 months of follow-up, and have a high success rate of anatomic reattachment with surgery. The occurrence of RD does not preclude improved final visual acuity.

Objective: This study aimed to report anatomic and visual acuity outcomes and complications after 1000-centistoke silicone oil was used as a retinal tamponade for the treatment of complex retinal detachments., Design: Prospective observational multicenter study conducted at community and university-based ophthalmology clinics., Participants: The study cohort consisted of 2439 patients (2573 eyes) treated for complex retinal detachments associated with cytomegalovirus (CMV) necrotizing retinitis or a non-CMV etiology, including proliferative diabetic retinopathy, giant retinal tears, proliferative vitreoretinopathy, or ocular trauma., Intervention: Vitrectomy surgery was performed for complex retinal detachment with 1000-centistoke silicone oil as the retinal tamponade., Main Outcome Measures: Anatomic outcomes were complete retinal attachment and macular attachment. Visual acuity outcomes were ambulatory vision (> or = 4/200) and preservation of preoperative visual acuity. Complications were rates of secondary intraocular pressure elevation (> or = 30 mmHg), hypotony (< or = 5 mmHg), corneal opacification (including band keratopathy, corneal edema, and corneal abrasions), oil emulsification, and cataract. Outcomes were assessed 6, 12, and 24 months after surgery., Results: At the 6-month examination, the retina was completely attached in 178 (78%) of 228 CMV eyes and in 855 (70%) of 1219 non-CMV eyes. The macula was attached in 216 (95%) of 228 and 1062 (89%) of 1189 CMV and non-CMV eyes, respectively. Ambulatory vision was noted in 151 (65%) of 234 CMV eyes and in 480 (38%) of 1251 non-CMV eyes. Visual acuity was preserved in 106 (46%) of 230 and 1035 (84%) of 1229 CMV and non-CMV eyes, respectively. The corresponding rates of complications for CMV and non-CMV eyes were: elevated intraocular pressure, 0 (0%) of 196 and 35 (3%) of 1196; hypotony, 11 (6%) of 196 and 228 (19%) of 1196; corneal opacity, 13 (6%) of 229 and 326 (26%) of 1248; emulsification, 3 (1%) of 211 and 29 (3%) of 959; and cataract in phakic eyes, 118 (64%) of 185 and 50 (63%) of 80., Conclusions: Retinal reattachment was achieved in the majority of eyes using vitrectomy and silicone oil retinal tamponade. Complication rates generally were less frequent in CMV eyes, but follow-up was shorter in this group of patients, largely because of reduced life expectancy. Cataract frequently developed in phakic eyes of study patients. Use of 1000-centistoke silicone oil can be considered in the management of complex retinal detachments associated with multiple etiologies.

The authors conducted a retrospective review of 32 patients with posterior retinal folds following retinal reattachment surgery. Twenty-eight of these patients underwent combined pars plana vitrectomy, fluid-air exchange with either internal drainage through a preexisting retinal break or external drainage of subretinal fluid, and scleral buckle. We believe these drainage techniques resulted in incomplete elimination of subretinal fluid, with resultant sequestration of fluid at the dependent border between attached and detached retina. Metamorphopsia and decreased visual acuity were noted in patients with folds involving the macula. The likelihood of fold formation may be greatly reduced by internal drainage through a posterior retinotomy combined with more complete removal of slowly gravitating fluid as it flows dependently to the drainage site.

The clinical source of 62 eyes that had been coded for macular degeneration and fibrovascular retinal pigment epithelial (RPE) detachment on fluorescein angiography was reviewed; 17 eyes had signs of a choroidal neovascular membrane (CNVM) at initial examination, and 30 eyes developed a definite CNVM during follow-up examination. Thus, 47 of the 62 eyes (76%) developed a CNVM in association with fibrovascular RPE detachments. Features of fibrovascular RPE detachments include: 1) focal, tiny hyperfluorescent spots at the level of the RPE arising in the mid and late frames of the angiogram, which do not correspond to drusen or foci of depigmentation (stippled hyperfluorescence); 2) intensification of these spots in the later stages of the angiogram; 3) slight enlargement of the spots in the late frames of the angiogram; 4) occasional presence of scant overlying subretinal fluid; and 5) minimal elevation of the RPE. Fibrovascular RPE detachments appear to be a distinct form of an RPE detachment. It is concluded that this sign is associated with a high risk of developing a frank CNVM and is thus a reliable indicator of occult neovascularization.

One hundred eyes in 98 patients were studied by fluorescein angiography and stereo color photography six weeks after successful scleral buckling surgery. Twenty-five percent of 67 phakic eyes and 40% of 33 aphakic eyes demonstrated cystoid macular edema. Older phakic patients were at significantly greater risk to develop cystoid macular edema than younger phakic patients. Seventeen percent of successfully repaired eyes demonstrated distortion of the macula by preretinal membranes; 16 of these 17 eyes showed leakage of fluorescein dye into the surrounding retina sometimes also causing cystoid edema. Either cystoid macular edema or macular distortion was present in 38% of the phakic eyes and 64% of the phakic eyes after successful retinal detachment surgery.
