Peripapillary intrachoroidal cavitation.

Abstract

Peripapillary Intrachoroidal Cavitation (PICC) can be appeared as an orangish lesion located at the outer lower edge of the myopic cone and confined to the intrachoroidal space. It is more common in patients with high myopia, older age, and greater axial length. The most accepted pathophysiological mechanism involves traction over a vulnerable sclera tissue at the myopic cone. PICC may present with visual field defects like mild glaucomatous neuropathy. Differential diagnosis with other choroidal pathologies is essential, and OCT-HD shows distinctive features in PICC. Additionally, OCT-A plays a crucial role in the diagnosis. We present 3 patients with PICC from our center, all of whom share advanced age, increased axial length, and myopia. All cases exhibit characteristic imaging alterations and visual field defects likely associated with the pathology.
