Purpose:
To describe a unique case of unilateral open angle glaucoma secondary to heterotopic bone formation in the anterior chamber angle.
Observations:
A 57 year-old male with an unremarkable history presented with right eye pain. Anterior segment examination demonstrated a solid, white deposit overlying the trabecular meshwork and peripheral iris associated with an intraocular pressure of 44 mmHg. The left eye examination was unremarkable. Biopsy of the material surprisingly showed heterotopic bone. Removal of the material and medical treatment were unable to adequately control the intraocular pressure and a trabeculectomy was successfully performed.
Conclusions And Importance:
This case demonstrates a unique cause of secondary open angle glaucoma: heterotopic bone formation in the anterior chamber angle.
