[Cystoid macular edema after rhegmatogenous retinal detachment surgery]

51 eyes of rhegmatogenous retinal detachment successfully reattached were prospectively studied with regard to the incidence of cystoid macular edema (CME). 14 eyes had CME 6 weeks after surgery, representing an incidence of 27.5%. No correlation was observed between CME and foveal involvement of the detachment, age of the patient, or the amount of subretinal fluid drained. CME is an important cause of postoperative visual impairment, and diagnosis is confirmed by fluorescein angiography. The angiographic features and classification of CME are described.
