When Cataracts Are Left Too Long: Understanding Hypermature Cataract and Normal Tension Glaucoma
Most people think of cataracts as a slow, harmless nuisance: vision gets cloudy over years, and eventually a routine surgery fixes it. That picture holds true for the vast majority of patients. But when a cataract is neglected for too long, it can progress into something far more complicated: a hypermature cataract , and in some cases, this brings along a rare but serious complication involving the optic nerve , even without the eye pressure rising in the way doctors usually expect. A cataract becomes "hypermature" when the lens has been clouded for so long that its proteins begin to break down and liquefy. The lens capsule , normally a tight, intact membrane, can weaken and even leak. In one well-known form, called Morgagnian cataract , the liquefied cortex allows the dense nucleus to sink toward the bottom of the capsular bag , visible on examination as a distinct shift within the lens.
