CHOROIDAL OSTEOMA IN AN INFANT.

Purpose: The aim of this study was to describe a case of choroidal osteoma with macular involvement in an infant who was treated with transpupillary thermotherapy.

Methods: This was a case report.

Results: An 11-month-old infant presented for retinopathy of prematurity follow-up examination and was found to have a three disk-diameter round, orange, subretinal, slightly elevated lesion with well-defined margins in the superior macula of the left eye. B-scan ultrasonography showed a slightly elevated, highly reflective choroidal mass with acoustic shadowing. A diagnosis of choroidal osteoma was made. Six months later, repeat examination under anesthesia showed the lesion to be increasing in size and encroaching on the fovea. Given demonstrated growth and the risk of central vision loss, the patient was treated with transpupillary thermotherapy. Subsequent EUAs, over a period of 4 months, have shown complete decalcification with no subsequent growth.

Conclusion: Choroidal osteomas are benign lesions that can be sight-threatening if located in the macula. Transpupillary thermotherapy in this case resulted in complete regression of a sight-threatening extrafoveal choroidal osteoma at 4-month follow-up.
