Pseudophakic Retinal Detachment
Survey of ophthalmology, 2003Co-Authors: Noemi Lois, David WongAbstract:Pseudophakic Retinal Detachment is a rare, but potentially serious, complication of cataract surgery. The incidence of pseudophakic Retinal Detachment following current surgical techniques of cataract extraction, including extracapsular cataract extraction by nuclear expression and phacoemulsification, is lower than that found after intracapsular cataract extraction. The risk of pseudophakic Retinal Detachment appears to be increased in myopic patients, in those patients in whom vitreous loss had occurred at the time of cataract surgery, and in patients undergoing Nd:YAG posterior capsulotomy. Most cases present to the clinician when the macula is already detached and the central vision is affected. When evaluating patients with pseudophakic Retinal Detachment, the fundal view is often impaired by anterior or posterior capsular opacification, reflections related to the intraocular lens, or poor mydriasis. Scleral buckling, pneumatic retinopexy, and primary pars plana vitrectomy, with or without combined scleral buckling, are the surgical techniques used to treat pseudophakic Retinal Detachment. Anatomical success rates are high after vitreo-Retinal surgery for pseudophakic Retinal Detachment, although a smaller proportion of patients recover good vision following surgery.

Rhegmatogenous Retinal Detachment: Prophylaxis
Management of Vitreo-Retinal Disease, 1999Co-Authors: Anthony H. Chignell, David WongAbstract:The object of prophylaxis is to prevent Retinal Detachment. Study of this subject has been neglected and as a result too many patients (approximately 50%) present with Retinal Detachment which has involved the macula. In many of these patients premonitory symptoms preceding the onset of the Retinal Detachment have been ignored either by the patients or unappreciated by those from whom the patient first seeks advice. In considering the need for prophylaxis, a balance has to be struck between the need to prevent Detachment against the risk, necessity and economics of treatment. The consideration of an eye for treatment mainly concerns those conditions which are known precursors of Retinal Detachment, i.e. Retinal breaks and those Retinal degenerations which may lead to Retinal breaks. Sometimes ‘normal retina’ is treated in high-risk eyes.

persistent foveal Retinal Detachment after successful rhegmatogenous Retinal Detachment surgery
American Journal of Ophthalmology, 2002Co-Authors: Norikazu Hagimura, Tomohiro Iida, Katsuya Suto, Shoji KishiAbstract:Abstract PURPOSE: To describe the tomographic features of the neurosensory retina after successful rhegmatogenous Retinal Detachment surgery DESIGN: Cohort study. METHODS: We prospectively examined cross-sectional Retinal images using optical coherence tomography (OCT) in 15 eyes of 15 consecutive patients (mean age, 46 years) who underwent scleral buckling surgery for treatment of rhegmatogenous Retinal Detachment. The retinas appeared reattached upon binocular stereoscopic indirect ophthalmoscopy. All eyes were examined at 1, 3, 6, and 12 months postoperatively. The time from onset of subjective symptoms of Retinal Detachment to Retinal surgery ranged from 4 to 66 days (mean, 14 days). The postoperative OCT findings and best-corrected visual acuity were statistically analyzed using the Mann–Whitney U test. RESULTS: The detached retinas appeared attached on ophthalmoscopy in all eyes 1 month postoperatively. OCT showed residual Retinal Detachment in four eyes (27%) at the fovea and in three eyes (20%) at the fovea and adjacent area. The remaining eight retinas (53%) were attached when examined tomographically. In six of the seven eyes with residual foveal Detachment by OCT, the retinas reattached spontaneously up to 12 months postoperatively. The postoperative best-corrected visual acuity improved gradually during 12 postoperative months in all 15 eyes. A substantial increase in visual acuity occurred when the fovea reattached in the six eyes with residual Detachment. CONCLUSIONS: Foveal Retinal Detachment may persist after successful Retinal Detachment surgery in eyes in which the fovea appeared to be attached on ophthalmoscopy. The residual foveal Detachment may explain, in part, the delayed visual acuity improvement after successful scleral buckling.

Neovascular complications associated with rubeosis iridis and peripheral Retinal Detachment after Retinal Detachment surgery.
American journal of ophthalmology, 1998Co-Authors: Gaetanor Barile, Stanley Chang, Jasond Horowitz, Vincents Reppucci, Williamm Schiff, Davidt WongAbstract:Abstract PURPOSE: To report clinical features and surgical management of neovascular complications associated with rubeosis iridis and peripheral Retinal Detachment after Retinal Detachment surgery in nondiabetic patients. METHODS: Seven consecutive eyes of seven nondiabetic patients who developed neovascular complications associated with rubeosis iridis and peripheral Retinal Detachment after scleral buckling and vitrectomy procedures were retrospectively reviewed. None of the eyes had clinical evidence of anterior segment ischemia or Retinal vascular disease, but each eye developed rubeosis iridis and neovascular complications. RESULTS: Of the seven eyes with rubeosis iridis and peripheral Retinal Detachment, six developed recurrent or progressive vitreous hemorrhage, and three developed progressive neovascular glaucoma. Four eyes underwent a revision procedure to repair the peripheral Retinal Detachment, and anterior proliferative vitreoretinopathy was found in each of these cases. Rubeosis iridis regressed in all three eyes in which surgery resulted in complete reattachment of the retina. In one eye with persistent peripheral Retinal Detachment and in the three remaining eyes that did not undergo revision surgery, rubeosis iridis persisted and was associated with long-term neovascular complications. Final corrected visual acuity was 20/70 to 20/400 in three eyes with total Retinal reattachment and no light perception to hand motions in four eyes with persistent peripheral Retinal Detachment and rubeosis iridis. CONCLUSION: Visually significant neovascular complications may occur in eyes that develop rubeosis iridis associated with peripheral Retinal Detachment after Retinal Detachment surgery in nondiabetic patients. Successful repair of the peripheral Retinal Detachment may induce regression of rubeosis iridis, reduce associated complications, and improve the long-term prognosis of these eyes.
