Abstract
This case series details macular findings in three female siblings who were found to be carriers of a previously unreported splice mutation in GPR143 (X-linked ocular albinism [OA1]). Presumed lyonization is responsible for both the subtle and varied findings in OA1 carriers, even among siblings, and especially in patients with darker skin pigmentation. In this series, we used green-light autofluorescence to reveal subtle subfoveal involvement and used optical coherence tomography angiography to uncover previously unreported narrowing of the foveal avascular zone, consistent with foveal hypoplasia.
