Abstract

Purpose: To describe the choroidal findings in eyes affected by choroidal osteoma imaged by enhanced depth imaging optical coherence tomography.

Methods: Retrospective case series.

Results: Seven eyes from five patients with choroidal osteoma were included in the study. Patients mean age of presentation was 26 years (median, 34; range, 6–37 years) and mean best-corrected visual acuity was 20/32 (median, 20/20; range, 20/20–20/200). Enhanced depth imaging optical coherence tomography examination revealed normal inner retina in all the cases and normal outer retina in three eyes. Abnormalities included irregularities in external limiting membrane (n = 2), myoid zone (n = 1), ellipsoid junction (n = 4), cone outer segments of photoreceptors (n = 5), and retinal pigment epithelium (n = 3). Choroidal analysis revealed thinned (n = 4) or non visible (n = 2) choriocapillaris, thinned (n = 3) or non visible (n = 4) medium vessels, and thinned large vessels layer (n = 4). The osteoma showed multiple intralesional layers (n = 5), a sponge-like appearance (n = 7), and intralesional vessels (n = 7). The sclero-choroidal junction was visible in all cases. Choroidal neovascularization was found in four eyes.

Conclusion: Analysis of eyes affected by choroidal osteoma revealed a characteristic sponge-like tumor appearance with the presence of multiple intralesional layers. The lesion showed a typical transparency with visibility of sclero-choroidal junction in all cases.

In Brief

Enhanced depth imaging optical coherence tomography analysis of 7 eyes in 5 patients with choroidal osteoma revealed a characteristic sponge-like appearance, with multiple intralesional layers and detectable sclero-choroidal junction in 100% of eyes.
