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
