Aim: To document the ocular involvement in HIV-infected individuals in Turkey and to compare the findings with those from other centers throughout the world. Methods: In this cross-sectional study, patients with HIV infection being monitored in a tertiary hospital in Istanbul were enrolled. Ocular examination was performed, and the prevalence of ocular manifestations determined. Results: In total, 93 patients were enrolled, of whom 37.6% had ocular pathology. HIV retinopathy was the most frequent retinal finding, affecting 8.6% of the enrolled patients, but none of the affected individuals had any ophthalmic complaints. There were no ocular lesions suggestive of cytomegalovirus (CMV) retinitis. Discussion: In contrast to the case in the developed world, sight-threatening infections are uncommon in Turkish HIV+ patients. The reasons for this are not clear, but it is possible that there are some genetic or environmental protective factors against CMV retinitis in the population studied. [ABSTRACT FROM AUTHOR]

Purpose: To analyze predisposing conditions in Turkish patients with CMV retinitis and to compare HIV-positive and HIV-negative patients., Methods: We reviewed medical charts and ocular images of 41 patients with CMV retinitis diagnosed between 1996 and 2019., Results: Eleven patients (27%) had HIV infection and 30 were immunocompromised from diverse causes. Initial visual acuity, type, zone, and extent of CMV retinitis, and response to anti-CMV treatment were not significantly different between the two groups. Vitreous haze and panretinal occlusive vasculopathy were the presenting features only in non-HIV patients, seen in 34% and 16% of eyes, respectively. Although not statistically significant, recurrent CMV retinitis was more common in non-HIV patients (17.4% vs. 4.3%/eye-year) and immune recovery uveitis was more common in HIV patients (43% vs. 26%/eye-year). Visual outcomes were similar. Final visual acuity of 1 logMAR or worse was significantly associated with the recurrence of CMV retinitis (odds ratio 9.67; p = 0.01) and also with the occurrence of immune recovery uveitis (odds ratio 4.31; p = 0.058)., Conclusions: Diverse immunocompromising conditions are more commonly associated with CMV retinitis than HIV infection in Turkish patients. Intraocular inflammation was more commonly associated with active retinitis in non-HIV patients and immune recovery uveitis was more common in HIV patients., (© 2021.
