abstract：:The oil-drop cataract is a common yet often overlooked cause of progressive vision loss. Although the nuclear change can be subtle on slitlamp biomicroscopic examination, retinoscopy reveals the classic oil droplet silhouetted against the red reflex. We present seven patients with oil-drop cataracts referred for neuro...
