PURPOSE: To report the association of antiretinal antibodies in patients with bilateral cystoid macular edema and retinitis pigmentosa. METHODS: In a prospective study, 30 consecutive patients with bilateral cystoid macular edema and retinitis pigmentosa were tested for antiretinal antibodies. As control subjects, 30 consecutive patients with retinitis pigmentosa who did not have cystoid macular edema and 50 normal subjects without retinitis pigmentosa or cystoid macular edema were tested for antiretinal antibodies. Laboratory personnel performing the antiretinal antibody testing were masked regarding the diagnosis of each patient. RESULTS: Twenty-seven (90%) of 30 patients with retinitis pigmentosa with cystoid macular edema had antiretinal protein antibody activity, compared with three (6%) of 50 normal controls (P < .001) and only four (13%) of 30 control patients with retinitis pigmentosa (P < .001). CONCLUSIONS: We found a significant association between cystoid macular edema and the presence of circulating antiretinal antibodies in patients who presented with retinitis pigmentosa and cystoid macular edema. This study suggests that patients with retinitis pigmentosa with cystoid macular edema may have an autoimmune process that is contributing to the formation of cystoid macular edema in retinitis pigmentosa, but to date, there is no direct evidence that the cystoid macular edema is caused by the antiretinal antibodies.
