A 74-year-old female with a past medical history of hypertension and type 2 diabetes mellitus presented for annual eye examination. Dilated fundus examination revealed multiple sparking, yellow-white, and refractile opacities in the vitreous cavity of the left eye. The opacities moved with ocular movement. The patient was asymptomatic and a diagnosis of asteroid hyalosis was made. Asteroid hyalosis is a common benign cause of vitreous opacities. It has been associated with several systemic diseases including diabetes and hypertension, as is the case in our patient. [1] Asteroid opacities are composed of calcium, phospholipids, and phosphorous.[1] While seldom visually significant, it is clinically relevant to avoid selection of silicone intraocular lenses in these patients. Treatment is observation.
