Overview
Optical coherence tomography, or OCT, is a noninvasive imaging test that provides high-resolution cross-sectional views of the retina and choroid. In inflammatory eye diseases, OCT helps clinicians see whether tissue damage is active or inactive, and it can reveal structural clues that are not obvious on routine examination.
This article focuses on inactive multifocal choroiditis with panuveitis and punctate inner choroidopathy, commonly grouped as MFCPU/PIC. These conditions are part of the same clinical spectrum and can leave behind pale, atrophic scars in the retina and choroid after inflammation has quieted down. The study compared OCT features of these lesions with scars caused by other inflammatory or infectious eye diseases that can look similar on examination.
