Goniodysgenesis is associated with which form of primary glaucoma?

• A. Open-Angle Glaucoma
• B. Secondary Glaucoma
• C. Closed-Angle Glaucoma (PACG)
• D. Normal Tension Glaucoma

Answer: (C)

Goniodysgenesis is a developmental abnormality of the iridocorneal angle. When the angle’s structure is faulty, it tends to narrow or close, obstructing aqueous humor drainage and leading to elevated IOP. This predisposition to angle closure is the hallmark of primary angle-closure glaucoma, so the form associated with goniodysgenesis is the angle-closure type. In contrast, open-angle glaucoma features a open angle with outflow problems at the trabecular meshwork, secondary glaucoma has a known cause, and normal tension glaucoma occurs with optic damage despite normal IOP and often with a wide angle.
