Retinal vasculature in KCNJ13 patients.

Ultra-wide field fluorescein angiography (FFA) using Optos (Dunfermline, Scotland) of the right eye from two unrelated patients with a missense mutation (p.Thr153Ile) in KCNJ13 compared to normal control male age 32 years (a–c). Panel Patient A-1, 20 years old, (d) color fundus images showing vasoproliferative response around the arcades, widespread pan-retinal photocoagulation scars overlying the pigmentary retinopathy; (e) shows leakage (first seen in arterial phase, data not shown) in the venous phase with extensive leakage in the late phase (f). Panel Patient B-2, 10 years old, (g) color fundus images showing patchy areas of nummular pigmentary retinopathy; (h) FFA shows hyperfluorescence in areas of retinopathy with an area of hypofluorescence at the macula which coincides with delineated area of chorioretinal atrophy (choroidal vessels can be seen), but no evidence of leakage at any phase (i).
