Angioid Streaks and Choroidal Neovascular Membrane Secondary to Pseudoxanthoma Elasticum: A Case Report

Angioid streaks (AS) are recognized as irregular, linear dehiscences of Bruch's membrane, often associated with systemic diseases. We present the case of a 50-year-old woman initially diagnosed with AS during a routine optometric examination. Subsequent ophthalmological evaluation revealed bilateral AS with calcified drusen. Two years post-diagnosis, she developed blurred vision in her right eye due to the choroidal neovascular membrane adjacent to the macular AS. Further evaluation uncovered clinical signs consistent with pseudoxanthoma elasticum (PXE), including characteristic skin lesions. A multidisciplinary approach involving ophthalmology, dermatology, and cardiovascular specialists was initiated. Histopathological confirmation of PXE was obtained through a skin biopsy. PXE, an autosomal recessive disorder characterized by elastin calcification, presents systemic manifestations necessitating comprehensive evaluation and monitoring. This case demonstrates the importance of recognizing ocular complications in PXE and advocates for early multidisciplinary intervention to mitigate potential vision and life-threatening outcomes.
