The implication of nonvisualized breaks in patients with pseudophakic retinal detachment is associated with lower rates of surgical success. This report decribes the results of a prospective trial to evaluate the efficacy of both scleral buckling surgery in the treatment of pseudophakic retinal detachment with undetected retinal breaks and pars plana vitrectomy techniques in the management of the cases that redetected after primary buckling surgery.\u0000\u0000\u0000PATIENTS AND METHODS\u0000This study represents 25 cases of pseudophakic retinal detachment with undiagnosed retinal breaks. In each case, we performed a scleral buckling that extended over the circumference of the retinal detachment. Pars plana vitrectomy with internal subretinal fluid drainage and long-term tamponade were performed on 7 patients with uncomplicated recurrent retinal detachments after primary buckling surgery. The mean duration of follow up was 32 months.\u0000\u0000\u0000RESULTS\u0000There were 25 eyes (24.5%) of pseudophakic retinal detachment with undiagnosed retinal breaks represented in our pseudophakic retinal detachment cases. Anatomic success was achieved after the initial scleral buckling surgery in 18 eyes (72%). The overall success rate was 92%. The visual acuity was 20/40 or better in 8 patients (32%), 20/80 to 20/40 in 6 patients (24%), 5/200 to 20/80 in 7 patients (28%), and light perception to hand movement in 4 patients (16%). Complications included vitreous hemorrhage, macular pucker, cystoid macular edema, and hypotony with proliferative vitreoretinopathy.\u0000\u0000\u0000CONCLUSION\u0000Scleral buckling surgery in conjunction with cryotherapy is effective in the initial treatment of pseudophakic retinal detachment with undetectable retinal breaks. Pars plana vitrectomy with internal fluid-gas exchange and long-term tamponade can be used to treat these patients with recurrent retinal detachment after primary buckling surgery to get a higher overall success rate.","PeriodicalId":19509,"journal":{"name":"Ophthalmic surgery and lasers","volume":"52 1","pages":"314-8"},"PeriodicalIF":0.0,"publicationDate":"2002-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84844404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Local therapy consisted of a cycle to each eye of 3 intravitreal injections of methotrexate (200 microg in a total volume of 0.1 cc) administered on days 1, 5, and 8, followed by a subtenon injection of dexamethasone phosphate (7.5 mg in a total volume of 0.3 cc) on day 9. This treatment cycle was administered 4 times for the right eye and 3 times for the left eye, at 4 to 6 week intervals. Electroretinography was used to assess retinal function prior to and during each treatment regimen. Complete regression of the lymphomatous infiltrates and resolution of the vitritis was observed with preservation of visual acuity and no changes on electroretinography. The effect was sustained for 24 months after termination of treatment in the absence of systemic chemotherapy, radiation treatments, or maintenance intravitreal injections. Local combined chemotherapy can be used to treat recurrent PIOL, and can serve as successful palliative therapy in patients for whom further treatment with systemic chemotherapy or radiation is contraindicated.","PeriodicalId":19509,"journal":{"name":"Ophthalmic surgery and lasers","volume":"9 1","pages":"329-33"},"PeriodicalIF":0.0,"publicationDate":"2002-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81559979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surgery was considered if best spectacle corrected visual acuity (BSCVA) was less than 20/70.
