We evaluated the cross-sectional image of various types of macular edema in 56 eyes using an optical coherence tomography, OCT. The series comprised diabetic retinopathy 43 eyes, branch retinal vein occlusion 6 eyes, central retinal vein occlusion 3 eyes, uveitis 2 eyes, posterior scleritis 1 eye and miliary angiomatosis 1 eye. The OCT findings showed three patterns of macular edema : sponge-like swelling of the retina (50 eyes), cystoid macular edema (28 eyes) and serous retinal detachment (4 eyes) . More than one pattern was often present in the same eye. Retinal swelling was more pronounced in the outer than the inner layer of the retina. Cystoid macular edema was mainly located in the outer retinal layer and, in persistent cases, cysts were fused together resulting in a large cystic cavity involving the entire retinal layers. Hard exudates appeared as high-reflective areas located in the outer and inner retinal layers. In eyes without cystoid macular edema, there was a medium negative correlation between the foveal thickness and visual acuity.
