Which term represents a stage of cataract development?

• A. Morgagnian cataract
• B. Juvenile cataract
• C. Capsular cataract
• D. Posterior subcapsular cataract

Answer: (A)

The idea being tested is distinguishing a progression stage from a specific type or location of cataract. Morgagnian cataract denotes a hypermature, advanced stage of cataract where the lens cortex has liquefied and the nucleus may sink in the liquefied material. This describes a clear point in the disease’s progression, not merely a location or a pediatric/non-stage descriptor. In contrast, juvenile cataract refers to cataracts seen in children (often congenital), capsular cataract points to the opacification involving the lens capsule, and posterior subcapsular cataract specifies the posterior subcapsular location of the opacity. These describe either age-related context or where the opacity is, not the stage of progression.
