73-year-old diabetic male with asteroid hyalosis affecting the right eye. Visual acuity remained 20/25 in the right eye
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.  Asteroid opacities are composed of calcium, phospholipids, and phosphorous. While seldom visually significant, it is clinically relevant to avoid selection of silicone intraocular lenses in these patients. Treatment is observation.
