Abstract
Purpose
To evaluate the efficacy of intravitreal bevacizumab injections combined with laser photocoagulation in the treatment of adult-onset Coats’ disease.
Methods
Thirteen eyes of 13 patients suffering from adult-onset Coats’ disease were retrospectively included and analyzed. All patients were treated at baseline using intravitreal bevacizumab injections combined with laser photocoagulation. Follow-up treatment was performed as necessary.
Results
The mean age of the subjects was 40.3 years, and the mean follow-up period was 24.8 months. The mean number of bevacizumab injections was 2.69, and the mean number of laser treatment sessions was 1.68. The mean baseline best-corrected visual acuity (BCVA) was 0.72 logarithm of the minimum angle of resolution (logMAR; 20/104 Snellen equivalent), while the mean BCVA at the final visit was 0.68 logMAR (20/95; P = 0.548). In three patients (23.0 %), BCVA had improved by more than 3 lines, and seven patients (54.0 %) showed stable BCVA (changes within 2 lines of visual acuity) after treatment. The mean central foveal thickness improved significantly, from 473 μm at baseline to 288 μm at the final visit (P = 0.023). Final BCVA was significantly correlated with a baseline BCVA (P < 0.001; ρ = 0.882). The final BCVA of patients who had subfoveal hard exudates at baseline was significantly worse than that of patients without such exudates (P = 0.005).
Conclusions
Intravitreal bevacizumab injection combined with laser photocoagulation may be an effective treatment option for adult-onset Coats’ disease. Both poor initial BCVA and the occurrence of subfoveal hard exudates at baseline were associated with poor prognosis and poor therapeutic response.
