Patient with a history of wet macular degeneration and glaucoma in both eyes. VA is 20/50, right eye, 20/80, left eye. Patient is treated with Eylea in both eyes. Enhanced depth imaging OCT reveals a small like form of a cyst which in fact isn't a cyst at all. This is called outer retinal tubulation in which degenerating photo-receptors may become arranged in a circular or ovoid fashion. This is sometimes misdiagnosed as cystic changes in the retinal pigment epithelium or sub-retinal fluid.
