A cataract is clouding of the ocular lens, causing decreased visual acuity. Cataract etiology may be congenital, age-related, traumatic, iatrogenic, or due to certain exposures. A cataract may result in leukocoria, or a “white pupil.” A congenital cataract may present with a blue-gray pupil as opposed to the typically observed white pupillary reflex often seen with the diagnosis of retinoblastoma. Cataracts in the aging population are often insidious in onset due to a slow clouding of the lens and are a major cause of blindness and visual impairment worldwide. Patients may experience blurred vision, changes in acuity or color differentiation, diplopia, and night vision changes.
