Multiple Therapy Approach for Stage 3 Coats Disease: Long-Term Follow-Up

PURPOSE: To assess long-term efficacy of a multiple therapy approach in the treatment and management of unilateral stage 3 Coats disease with exudative retinal detachment. METHODS: 2 eyes of 2 young patients suffering from unilateral stage 3 Coats disease underwent a multiple therapy approach consisting of surgical drainage of exudative subretinal fluid + one simultaneous and up to one subsequent intravitreal injection of bevacizumab + multiple (up to 3) laser photocoagulation sessions of retinal nonperfusion areas and leaking Coats vasculature. RESULTS: Complete reabsorption of SRF and retinal reattachment were observed in both cases over the follow-up. In no cases, we observed progression to phthisis bulbi. No bevacizumab-related complications were observed. Epiretinal membrane onset was detected in one eye at the end of follow-up. CONCLUSION: The management and treatment of this rare and degenerative disease in young subjects are still a challenge. The described technique is less invasive than conventional intraocular surgery and may be preferable to halt the devastating progression of the disease.
