    Cytomegalovirus (CMV) retinitis usually affects severely immunosuppressed individuals. We report two immunocompetent patients who developed CMV retinitis.
    Case 1 was a 65-year-old man who was referred to us with blurred vision and floaters of 2 weeks duration in his left eye. Slit-lamp biomicroscopy showed keratic precipitates, aqueous cells, and vitreous opacity in his left eye. Funduscopic examination revealed yellow-white retinal lesions with arterial sheathing in the superotemporal midperiphery. Case 2 was a 63-year-old man who presented with a 2-week history of blurred vision in his left eye. Ophthalmologic examination of the left eye showed keratic precipitates, aqueous cells, vitreous opacity, and yellow-white lesions in the superotemporal peripheral retina. In both cases, CMV DNA was detected in the aqueous humor and therefore the diagnosis was CMV retinitis. CMV retinitis in both cases was indolent and was resolved in one month without treatment with antiviral drugs. Although both patients had diabetes mellitus, the results of their laboratory examinations were unremarkable and they were immunocompetent.
    Unlike CMV retinitis in immunocompromised patients, CMV retinitis in immunocompetent patients had significant anterior and vitreous inflammation but did not require antiviral treatment. A possible association between CMV retinitis and diabetes mellitus was suggested.
