A 6-year-old boy presents with leukocoria in the right eye. Dilated fundoscopy under anesthesia reveals the findings shown in the diagram. The structures marked **A** are telangiectatic light-bulb aneurysms. Which of the following best describes the PRIMARY PATHOPHYSIOLOGIC mechanism responsible for the formation of these aneurysms in Coats disease?
A 5-year-old boy presents with leukocoria detected on routine examination. Fundoscopy reveals yellow subretinal exudates and bulbous, dilated, tortuous vessels in the temporal periphery. The structure marked **B** in the diagram shows the characteristic appearance of Coats disease with telangiectasia and exudation. Which of the following best describes the underlying pathophysiological mechanism responsible for the progressive exudation seen in this condition?
A 7-year-old boy presents with leukocoria and strabismus. Funduscopic examination reveals unilateral retinal vascular abnormalities with telangiectasias and "light bulb" microaneurysms predominantly in the temporal and inferior retina. The structure marked **B** (yellow subretinal lipid exudate) is noted on examination. Which of the following best explains the pathophysiology underlying the formation of this exudate in Coats disease?
