PURPOSE-To determine the morphological features of choroidal osteoma through multimodal imaging.
METHODS-A retrospective observational case series of 8 eyes of 6 patients diagnosed as choroidal osteoma in a tertiary eye care centre in South India. All patients underwent SD-OCT, fundus autofluorescence (FAF) and ultrasonography.
RESULTS-Mean age of presentation was 29.2 years with 83% being females. Mean visual acuity at presentation was 0.55 logMAR. 2 eyes with CNVM were treated with anti VEGF. 1 case had posterior scleritis. B-scan showed hyper echoic choroidal mass with pseudooptic acoustic shadowing. 75% of FAF showed hyperautofluorescence and 25% showed isoautofluorescence. SD-OCT revealed hyperreflective lamellar lines and tubular channels. 50% had SRF, 37.5% had RPE changes and 37.5% had cystic changes.
CONCLUSION: Multimodal imaging is an essential tool in better understanding the micro-morphology of choroidal osteoma as it aids in diagnosis, follow up and treatment.
