One hundred fifty-seven patients with subretinal neovascularization (SRN) were treated in a prospective, nonrandomized, consecutive study with the krypton red laser (KRL). The patients were analyzed with respect to age, etiology of the SRN, location of the SRN, and pre- and post-treatment visual acuity in patients with at least three months follow-up. Previous studies have not investigated KRL photocoagulation within the foveal avascular zone (FAZ). The results of this study compare favorably with other large series in which patients with SRN located outside the FAZ were treated with the argon blue-green laser (ABGL)

A retrospective analysis of a consecutive series of patients treated with krypton red laser (KRL) photocoagulation for subretinal neovascularization (SRN) secondary to drusen-related macular degeneration (DMD) was carried out to investigate the frequency and nature of recurrent neovascularization (recurrence). A classification of various types of recurrences based on the clinical and fluorescein angiographic features and the onset of their appearance in the postoperative course was used in this study. Patient, fundus, and membrane variables were examined in search of relevant high risk factors predisposing to recurrences. The membrane's proximity to the fovea and its relative lack of pigmentation were individual factors which were associated with a high risk of recurrence (P less than 0.05 for distance and P = 0.005 for color). Multivariate analysis also indicated that a greater distance from the fovea (P less than 0.05) and a darker color (P = 0.002) were favorable features to the primary membrane, reducing the probability of a recurrence. Overall, 39% of the patients experienced recurrences (23% of the patients had treatable recurrences and 16% had non-treatable recurrences extending under the center of the fovea). The membranes recurred predominantly at the margin of the photocoagulation burn. The recurrences were also noted relatively early in the postoperative course, 65% within two months after photocoagulation of the primary membrane. The fluorescein angiographic and clinical nature of these membranes and the visual effect of retreatment are also discussed in the paper

Twenty-five patients with central serous pigment epitheliopathy (CSP), also known as central serous chorioretinopathy, have been observed to have inferior hemispheric retinal pigment epithelial atrophic tracts, presumptive of antecedent retinal detachments. Five of these patients were noted to have clinically discernible, dependent peripheral retinal detachments. The clinical and fluorescein angiographic features of these patients are reviewed. Alterations in the retina, the retinal pigment epithelium (RPE) and the choroid are also described. They include the commonly associated manifestations of CSP such as RPE leaks and macular detachment as well as some newly recognized disturbances such as retinal capillary dilatation (telangiectasia), retinal capillary leakage, retinal lipid deposition, cystoid macular edema, choriocapillaris atrophy, choroidal neovascularization and disciform scarring

Concepts related to the pathogenesis of aphakic cystoid macular edema (ACME) are presented with reference to possible management considerations. The role of certain aspects of cataract surgical technique, laser photocoagulation, vitreoretinal surgery and medical therapy utilizing corticosteroids and antiprostaglandins are discussed. The difficulties encountered in the evaluation of the efficacy of any treatment modality advocated for ACME are reviewed. Preliminary results of studies on the medical treatment of ACME currently under investigation by the author are also presented

A Modified Amsler Grid, the size of a conventional credit card, has been developed as a suitable alternate to the full-scale version. The size of the grid makes it extremely convenient for patients in our highly mobile society. When viewed twice (vertically and horizontally), it corresponds well to the topography of the central macula. In this capacity the Modified Amsler Grid is a useful adjunct to the overall management of patients with macular diseases which may potentially be associated with exudative manifestations
