Abstract

Purpose: To present clinical characteristics of Coats disease at Vietnam National Institute of Ophthalmology. Methods: Descriptive study based on case series was performed of 30 patients diagnosed with Coats disease at Vietnam National Institute of Ophthalmology from June 2021 to September 2022. Results: The mean age of patients at diagnosis was 9.13 ± 5.38 with 29 males and 1 female. The rate of diseased eyes was 43.3% in the right eye, 53.3% in the left eye and one patient had disease in both eyes. The most common symptom was decreased visual acuity (90%) followed by strabismus (43%) and then leukocoria (36%). Mean corrected visual acuity was 1.9±1.06 logMAR. Retinal telangiectasia was most commonly involved temporal quadrant in 80% of eyes while just involved nasal quadrant in only 20% of eyes. The mean range of retinal telangiectasia was 7.00 ± 2.81 clock hours. Macular-off retinal detachment was present in 45% of eyes and macular edema was present in 42% of eyes. Stage 2B was the most common with 10 eyes while there was only 1 eye at stage 2A. The mean age of patients with diagnosis at stage 2A to stage 3A was 10.63 ± 6.11, at stage 3B to stage 5 was 6.47 ± 3.20. Conclusion: Coats disease commonly occurs unilaterally in young males. Typical disorders are peripheral telangiectasia and temporal retinal exudation. The common stage in the study is 2B. Early-onset patients often have more severe symptoms.
