Optical Coherence Tomographic Measurement of Choroidal Thickness in Eyes with Fuchs Heterochromic Iridocyclitis

Abstract

Fuchs Uveitis Syndrome is a type of chronic and usually unilateral uveitis characterized by iris heterochromia and corneal endothelial deposits and a predisposition to cataracts and glaucoma. The aim of this study was to comparison of optical coherence tomographic measurement of choroidal thickness in eyes with Fuchs Heterochromic Iridocyclitis. Materials and Methods: The present study was a cross-sectional study that was conducted over a period of 6 months in 2020 at the Nikoukari Educational and Medical Center of Tabriz. Eighteen patients with unilateral Fuchs Heterochromic Iridocyclitis were studied by available sampling method. Diagnosis of Fuchs Heterochromic Iridocyclitis in these patients was made according to the criteria of Kimura et al. Choroid thickness was measured by an ophthalmologist using OCT software. The thickness of the retina and choroid was first recorded in the submacular area after determining the segmentation according to the definition of borders and software measurement, and then in the 3 mm area of the temporal and nasal macula, the thickness of the choroid and retina were measured in the same way after determining the segmentation, and then the data were statistically analyzed. Results: In this study, the mean (standard deviation) age of the subjects was 36.83 (±6.4) years. Most of the subjects in this study were men with 11 cases (61.1%). Among the eye thickness parameters in the studied patients, the parameters of choroid thickness in submacular region (P = 0.027) and choroid thickness in macular nasal (P = 0.001) in the involved eye were significantly thinner than healthy eye.
