To report a case of bilateral scleral hyaline plaques in an elderly male patient. Scleral hyaline plaques are commonly noticed but rarely diagnosed. These are typical areas of hyalinization over the insertions of horizontal rectus muscle.

A 75-year-old man presented to the hospital complaining of scleral color change. External examination of both eyes revealed oval, slate-gray lesions measuring approximately 3.5 mm in diameter, located just anterior to the insertion of the medial rectus muscle in both eyes. On anterior segment optical coherence tomography of the lesions, thinned sclera and plaque were observed. There was no change in the lesion on the 3-year follow-up visit.
