Clinical analysis of youth patients with retinal arterial occlusions / 中华眼底病杂志

ABSTRACT

Objective To observe the clinical features of retinal arterial occlusion (RAO) in youth.Methods This is a retrospective case review.Nine patients (9 eyes) with RAO were enrolled in this study.There were 6 males (6 eyes) and 3 females (3 eyes).The average age was (14.22± 3.93) years.The best-corrected visual acuity (BCVA),indirect ophthalmoscopy,fundus color photography and fundus fluorescein angiography were performed.All patients underwent systemic evaluation including blood routine,erythrocyte sedimentation rate,blood lipids,vasculitis screening,homocysteine level,antiphospholipid antibody,blood coagulation,neck vascular ultrasound,and cardiac color ultrasound and electrocardiogram examination.All patients received oxygen therapy,blood medications and symptomatic treatment.Meanwhile,the patients with autoimmune diseases were received systemic glucocorticoid therapy.The follow-up was ranged from 6 to 12 months.The visual acuity and fundus change before and after treatment were compared.Results among 9 patients,one patient had systemic lupus erythematosus,one patient had congenital heart disease,one patient had hypergammaglobulinemia,and carotid artery color ultrasonography showed that the internal carotid artery vessels faltered in 2 cases.The BCVA was 0.01-0.12.Among 9 eyes,there were 5 eyes (55.6％) with retinal branch artery occlusion (BRAO),2 eyes (22.2％) with central retinal artery occlusion (CRAO),2 eyes (22.2％) with ciliary retinal artery occlusion (CLAO).CRAO eyes showed positive RAPD (relative afferent pupillary defect),fine retinal artery and the corresponding vein,pale white retinal edema in posterior area and macular cherry-red spot.BRAO eyes manifested as inferior temporal artery occlusion and pale white retinal edema around them.CLAO eyes showed temporal ligulate grey-white retinal edema.At the last follow-up,BCVA improved and retinal vessels returned to normal in 7 eyes (77.8％);BCVA unchanged and no improvement in fundus in 2 eyes (22.2％).Conclusion Adolescent RAO is mostly partial occlusion,the prognosis is generally good after early active treatment.
