A Case of Asteroid Hyalosis In a Diabetic Patient
The present case has been reported in NEJM.

A 54-year-old woman with type 2 diabetes mellitus presented to the ophthalmology clinic for a routine dilated fundus examination. She had a history of cataracts, which had been treated successfully with posterior-chamber intraocular lenses in both eyes.

Slit-lamp examination of the left eye revealed multiple sparkling, white, globular, refractile, dotlike opacities in the vitreous cavity (see video). The opacities moved with ocular movement and returned to their original position after movement stopped. The vitreous of the right eye appeared normal.

The visual acuity was 20/20 in each eye, and the fundus in each eye was normal. A diagnosis of asteroid hyalosis was made. Asteroid hyalosis is a benign condition that is often unilateral, as in this patient, and is associated with older age. The asteroid bodies are composed of calcium, phosphorus, and various phospholipids.

Although asteroid hyalosis may hamper the view of the retina during clinical examination, the visual acuity usually remains unaffected. Given the benign nature of this condition and this patient’s normal visual acuity, no treatment was recommended.
