The clinical features of primary uveal lymphoma of four cases / 中华眼底病杂志

ABSTRACT

Objective:To investigate the clinical, ophthalmological and pathological features of primary uveal lymphoma.Methods:Retrospective clinical study. From 2012 to 2018 in Beijing Tongren Eye Cener, 4 cases and 4 eyes of patients with primary uveal lymphoma were included in the study. Among them, 3 cases were male and 1 case was female. The average age was (54 ± 13.58) years old. The average time from initial diagnosis to pathological diagnosis was (18.50 ± 9.29) months. 3 cases were enucleated and 1 case was biopsied. Extranodal marginal zone lymphoma (EMZL) of the mucosa associated lymphoid tissue (MALT) was confirmed by pathological examination. BCVA, fundus color photography, color Doppler ultrasound and orbital MRI were performed in all eyes. UBM, OCT, FFA and ICGA were performed in 2 eyes, 3 eyes, 3 eyes and 2 eyes respectively. The clinical, imaging and pathological changes were observed. Following up time was ≥ 6 months.Results:At the initial diagnosis, BCVA was 0.6, 0.02 and 0.01 in 1, 2 and 1 eye respectively. Choroid, ciliary body and iris were involved in 3 eyes, choroid in 1 eye. The fundus of the eyes showed infiltration of choroid in yellow and white color, and the lesions were beyond the vascular arch to the equator and peripheral areas. Color Doppler ultrasonography showed that choroidal diffuse thickening and extrascleral extension (ESE) which was the corresponding hypoechoic areas behind the sclera. Among them, ESE showed crescent thickening in 1 eye and nodular thickening in 3 eyes. UBM showed that the echo of ciliary body was thicken and the internal echo was decreased with the iris involved. OCT showed that RPE was wavy and local retinal neuroepithelial layer detached. FFA showed that the early lesions were mottled with strong and weak fluorescence, and the late fluorescence leakage. The posterior wall of the eyeball was thickened and enhanced in MRI.Conclusion:The clinical manifestations of uveal lymphoma are various, color Doppler ultrasound has characteristic manifestations and ESE of crescent or nodular thickening is valuable in diagnosis.
