Fluorescein angiography after retinal detachment microsurgery.

The eyes of 78 patients who underwent retinal detachment microsurgery (82 eyes) were prospectively evaluated postoperatively with fluorescein angiography. Of these 14.6% showed angiographic evidence of cystoid macular oedema (CMO.). A significantly greater risk of developing cmo was discovered in aphakic eyes (30% CMO.) as compared to phakic eyes (7% CMO.) and in eyes where the maculae were detached pre-operatively (23% CMO.), as compared to eyes where the maculae were attached pre-operatively (5% CMO.). Eyes which had undergone several surgical procedures for retinal reattachment (38% CMO.) were compared to eyes which had undergone only one surgical procedure (6.5% CMO.). It was found that 4.9% of the 82 eyes showed cellophane premacular membrane without dye leakage. A further 6% of the eyes showed premacular membranes associated with dye leakage. No statistically significant risk factor associated with the development of macular pucker was disclosed in this series.

[Acute panendothelial retinal leakage in juvenile diabetes (author's transl)].

Four cases of acute panendothelial retinal leakage in juvenile diabetes are presented. One patient showed acute disc swelling mimicking optic disc new vessels, one had acute cystoid maculopathy, two had both diffuse retinal leakage and optic disc edema. Acute disc swelling and acute cystoid maculopathy in juvenile diabetes are probably variations of the same clinical entity. Acute endothelial leakage can involve either the epipapillary and peripapillary radial capillaries (acute disc swelling), the retinal capillaries of the posterior pole (acute cystoid maculopathy), or the entire epipapillary and retinal capillary network (diffuse panendothelial retinal leakage). Photocoagulation treatment is not indicated in the management of this specific clinical entity. In fact, acute panendothelial retinal leakage in juvenile diabetes seems to be related to poor blood sugar control. In 3 cases the"spontaneous" favorable course of the disease was probably related to the modification of insulin dosage after discovery of the ocular disease.

[Topographic study of angiographic lesions in central serous retinopathy (author's transl)].

The 595 angiographic lesions observed in 233 eyes of 169 patients affected with central serous retinopathy have been classified upon their localization. 498 angiographic lesions (83.7 percent) are located within a three optic disc diameter area centered by the foveola. Among them 20 are located right behind the foveola, 113 are located in the upper temporal quadrant, 166 in the upper nasal quadrant and 85 in the lower temporal quadrant. The relative density of the angiographic lesions decreases from the center of the macula to the periphery. 97 angiographic lesions (16.3 percent) are located beyond the three optic disc diameter central area. 41.1 percent of the lesions are situated behind the macula or/and behind the papillo-macular bundle. Therefore only 58.9 percent of the angiographic lesions observed in central serous retinopathy can be treated without any risk by means of photocoagulation.
