Background/Aim:
To describe demographic and clinical characteristics, treatment, and visual prognosis of Coats disease in Hispanic patients.
Methods:
A retrospective chart review was performed on nine patients (ten eyes) diagnosed with Coats disease in our two clinical centrers from 2004 - 2017.
Results:
Mean age at diagnosis was 5.5 years (range 1 - 12 years) and mean follow-up time was 48 months (range 9 - 108 months). Eight patients (89%) were male and had unilateral disease and one (11%) female patient had bilateral disease. In 40% of the cases, patients were asymptomatic. Visual acuity at first presentation was worse than hand motion in 60% of the eyes. Half of the eyes (5/10 eyes, 50%) had exudative retinal detachment (≥ stage IIIA). Vascular ablation with cryotherapy combined with retinal photocoagulation was the most frequent therapeutic approach (40%). Despite anatomical success at 6 months in 100% of the treated eyes, visual outcome at 1 year of treatment was poor (worse than 20/200) in 70% of the cases.
Conclusions:
In our case series, patients were mostly asymptomatic on presentation, with severe stages of Coats disease. Even with anatomical success after surgical treatment in all treated cases, long-term visual prognosis remained very limited.
