ABSTRACT
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.

PURPOSE: To study the incidence and risk factors of retinopathy of prematurity (ROP) in premature infants examined in a tertiary hospital in Istanbul. METHODS: Data of infants screened for ROP from April 2007 to September 2009 were retrospectively reviewed. Possible risk factors and eye examinations were recorded and analyzed using the chi-square test and univariate and multivariate regressions. RESULTS: ROP was detected in 177 (34.3%) of the 517 infants enrolled in the study; 64 had mild ROP (77.4%) and 38 had severe ROP (22.6%). The mean gestational age and birth weight of patients who were treated for ROP were 28.6 ± 2.3 and 1,143.5 ± 337.4, respectively. Two of these infants had a gestational age of 32 g or greater and three had a birth weight of 1,500 g or greater. The multivariate regression analyses showed gestational age, birth weight, sepsis, respiratory distress syndrome, and length of oxygen therapy as independent predictors of ROP. CONCLUSION: The incidence of ROP observed in this study was higher than that in developed countries and relatively more mature infants were affected. Criteria including gestational age of less than 34 weeks or birth weight of less than 2,000 g would have identified all infants who were at risk.
