ARTICLE HIGHLIGHTS
Research background

Coats disease is an idiopathic exudative outer retinopathy caused by abnormal retinal vascular development

Research motivation

The disorder usually affects adolescents. However, a recent study reported that 7% of cases occur in adults.

Research objectives

We investigated the long-term outcomes of intravitreal conbercept injection with laser photocoagulation to treat Coats disease in adults.

Research methods

This is a retrospective case series on 8 adult patients (eight eyes) diagnosed with Coats disease. Patients were treated with intravitreal conbercept injection and 532-nm laser photocoagulation.

Research results

There was a significant upward trend in the best-corrected visual acuity after treatment, which was maintained for at least 3 years.

Research conclusions

Intravitreal conbercept injection plus 532-nm laser photocoagulation may be a feasible treatment for Coats disease in adult patients.

Research perspectives

Prospective randomized clinical trials are needed to confirm our findings and establish whether conbercept is a useful adjunct therapy for Coats disease.
