PURPOSE: To evaluate the long-term safety and efficacy of adjuvant intravitreal anti-VEGF therapy in juvenile Coats disease. METHODS: This retrospective, observational study included a total of 62 eyes in 62 pediatric patients with juvenile Coats disease treated with intravitreal anti-VEGF agents followed for a mean of 67.08 months (ranged from 60 to 93 months). All affected eyes were managed initially with one session of ablative treatment plus adjuvant intravitreal anti-VEGF agent (0.5 mg/0.05 ml ranibizumab or conbercept). Ablative treatment was repeated if telangiectatic retinal vessels were not completely regressed or recurred. Anti-VEGF therapy was repeated if subretinal fluid or macular edema still existed. Treatments above were repeated every 2 to 3 months. We reviewed clinical and photographic records of patients including the demographics, clinical characteristics and interventions. RESULTS: At final visit, all 62 affected eyes had partially or completely disease resolution; none progressed to advanced stage namely neovascular glaucoma or phthisis bulbi, respectively. No ocular or systemic side effects related to intravitreal injections were observed during follow-up. In terms of 42 affected eyes that could cooperate with visual examination, best corrected visual acuity improved in 14 (14/42, 33.3%) eyes, stabled in 25 (25/42, 59.5%) eyes, and worsened in 3 (3/42, 7.1%) eyes. In the field of complications, 22 (22/62, 35.5%) eyes developed cataracts; 33 (33/62, 53.2%) eyes developed vitreoretinal fibrosis, of whom 14 (14/33, 42.4%) eyes in the subgroup of stage 3B developed progressive TRD; 40 (40/62, 64.5%) eyes developed subretinal fibrosis. Multivariate regression analysis showed increased clinical stage may be associated with the development of vitreo- and subretinal fibrosis (adjusted odds ratio:16.77,17.59; 95% CI:4.50-62.53, 3.98-77.86, respectively, all P < 0.001). CONCLUSION: Adjuvant intravitreal ranibizumab or conbercept combined with ablative therapies may be a long-term safe and effective treatment for juvenile Coats disease.
