1231: How to identify retinal tears?

ACTA OPHTHALMOLOGICA, Issue 2010
JP BERROD
Purpose Locating the retinal tear(s) in rhegmatogenous retinal detachment witout PVR is the first step of a successful treatment. The purpose of the course is to present the different techniques and rules to examine the retina in order to detect and locate all the tears. Methods We emphasised the 3 Lincoff's rules that permit concentration of the efforts to a small area of the periphery to identify the breaks. More than one break is present in 50% of eyes. Hence, there is a need to inspect the rest of the fundus including areas of attached retina. Results In the evaluation, one needs to stress the importance of good binocular indirect ophthalmoscopy with scleral depression or direct ophthalmocopy with slitlamp and 3 mirror contact lens. Vitrectomy can be indicated in certain cases of failure to detect breaks. In the presence of severe PVR the surgery would involve thorough cleaning of the entire retina, hence it may not be so important to identify all breaks preoperatively. Conclusion A minimal rate of postoperative failure for rhegmatogenous retinal detachment can only be achieved if a maximal preoperative search for the retinal breaks has been performed. [source]

Incidence of redetachment 6 months after scleral buckling surgery

ACTA OPHTHALMOLOGICA, Issue 2 2010

Abstract. Purpose:, The preoperative and intraoperative clinical variables associated with redetachment and/or a poor visual outcome following scleral buckling (SB) surgery for rhegmatogenous retinal detachment (RRD) have mainly been studied after a short follow-up. This study aimed to analyse long-term effects by following patients for at least 6 months. Methods:, In a retrospective survey we evaluated the data of 436 eyes that underwent SB surgery. Postoperative data were collected at 3-month intervals. Results:, After a mean follow-up period of 51 months, anatomic reattachment was achieved in 76% after one SB procedure, with a final reattachment rate of 97% after additional vitreoretinal procedures. In total, 104 eyes developed redetachment during follow-up. After more than 6 and 12 months of follow-up, 32 eyes (7%) and 20 eyes (5%), respectively, developed redetachment. Multivariate regression analysis showed that recurrent redetachment and more than 7 days of visual field loss were significant predictors for a poor postoperative visual outcome at 12 months. A cumulative size of the tear of more than three disc diameters was a significant predictor of recurrent RRD. Conclusion:, Conventional SB surgery is a reliable procedure in a selected group of eyes with primary RRD. However, in eyes with a retinal tear with a cumulative size of more than three disc diameters, a primary vitrectomy should be considered. Taking into account that 7% of eyes developed redetachment after 6 months, a longer follow-up period seems necessary to evaluate the anatomical and visual outcomes after SB surgery. [source]

Discriminate characteristics of photopsia in posterior vitreous detachment, retinal tears and retinal detachment

OPHTHALMIC AND PHYSIOLOGICAL OPTICS, Issue 1 2010
Jonathan F. B. Goodfellow
Abstract Aims:, To characterize photopsia in posterior vitreous detachment (PVD), retinal tears (RT) and rhegmatogenous retinal detachment (RRD). Methods: Seventy seven patients presenting to an eye emergency department and vitreoretinal clinic with photopsia had documentation of their symptoms. Results:, A total of 27 patients had PVD alone, 7 had RTs and 25 RRD. In patients with isolated PVD, photopsia were temporal (94%), lasting seconds (81%) and vertically orientated (59%) flashes. Patients with photopsia located in quadrants other than temporal were more likely to have RRD (p = 0.0003). Patients with an oblique or horizontal orientation of their photopsia were likely to have RRD or RT (p = 0.001, specificity 96%, sensitivity 40%). Conclusions:, Most patients with PVD have a typical presentation of photopsia, with temporal, vertically orientated, momentary flashes. Patients with RTs or RRD may describe subtle differences in their photopsia which may raise the index of suspicion for the presence of a complication from PVD. [source]

Minor surgery for the repair of retinal detachment emanating from retinoschisis

ACTA OPHTHALMOLOGICA, Issue 3 2009
Harvey Lincoff
Abstract. Purpose:, To propose a mechanism for the development of the outer layer retinal tears that occur with retinoschisis and the detachment emanating from it that is consistent with the limited extent of the detachment and the response to binocular occlusion and local buckles. Methods:, A consecutive series of 24 patients with retinoschisis, collected over 15 years, was analysed. Seven patients developed a symptomatic retinal detachment emanating from breaks in the outer layers of retinoschisis. The detachments responded to binocular occlusion, a sponge buckle, or a temporary balloon buckle and laser coagulation to the edges of the breaks. Results:, Two retinas attached completely after 48 hr of binocular occlusion, four responded to local sponge buckles and one to a temporary balloon buckle. All attached without drainage of subretinal fluid. Final visual acuity was 20/20 in six eyes and 20/25 in one eye. Conclusion:, The detachment emanating from retinoschisis responds to ocular rest or a local buckle to breaks in the outer layers. It is proposed that the mechanism for the detachment that emanates from retinoschisis is intraretinal traction by residual transretinal fibres at the edge of the schisis cavity. [source]
