Ultra-wide field fluorescein angiography demonstrates peripheral telengectatic vessels, nonperfusion, and leakage in Coats disease. The patient subsequently underwent an EUA with targeted panretinal photocoagulation

A negative UWF-FA, meaning one without significant ischemia or leakage, can guide the decision to observe with serial examinations and photographs and eliminate the need for an exam under anesthesia as shown in Fig. 4.
In a patient with retinopathy of prematurity previously treated with laser ablation, ultra-wide field fluorescein angiography demonstrates no leakage. Notably there is temporal dragging

On the contrary, a UWF-FA with active leakage or neovascularization as in a patient with proliferative diabetic retinopathy or Coats disease may indicate the need for additional panretinal photocoagulation (Fig. 5).
