A 49year-old diabetic man presented to the ophthalmology clinic to establish care. After refraction, his best-corrected visual acuities were 20/25 in both eyes. Dilated fundus examination showed a right eye with a normal vitreous humor and a benign retinal exam without evidence of diabetic retinopathy (Fig. 1A). The left eye exhibited numerous mobile refractile vitreous opacities limiting the view through the posterior segment to the retina (Fig. 1B).
