PURPOSE: To characterize peripapillary intrachoroidal cavitation (PICC) in highly myopic participants and its associated risk factors.
METHODS: This observational, cross-sectional study recruited 890 Chinese participants with bilateral high myopia, defined as ≤-6.00 diopters spherical power. Fundus photography and spectral-domain optical coherence tomography were used to determine the presence of PICC, defined as a yellow-orange lesion adjacent to the disc border with a corresponding intrachoroidal hyporeflective space.
RESULTS: Among 890 participants, 884 right eyes were included for analysis. The rate of PICC was 3.6% (32 eyes). Peripapillary intrachoroidal cavitation was observed in two eyes without myopic retinal lesions, nine eyes with tessellated fundus only, 16 eyes with diffuse chorioretinal atrophy, and five eyes with patchy chorioretinal atrophy. The most commonly affected area was inferior disc border (87.5%), followed by multiple (9.4%) and superior (3.1%) disc borders. The multiple linear logistic regression model showed that older age, more myopic spherical equivalent, and longer axial length were associated with the presence of PICC.
CONCLUSION: Peripapillary intrachoroidal cavitation was present in 3.6% of highly myopic eyes. It was more common in eyes with a higher myopic maculopathy category. Older age, more myopic spherical equivalent, and longer axial length were risk factors for the presence of PICC.
