What are major causes of visual field loss?

Visual field loss can occur due to a variety of medical conditions, and among the choices provided, the major causes include glaucoma, retinal detachment, and stroke.

Glaucoma is a condition characterized by increased pressure within the eye, which can lead to damage of the optic nerve and gradual loss of peripheral vision. As the disease progresses, it can result in significant gaps in the visual field.

Retinal detachment occurs when the retina separates from its underlying supportive tissue, leading to a sudden loss of vision in part of or all of the visual field. This is considered a medical emergency that can result in permanent vision loss if not promptly treated.

A stroke, particularly one affecting areas of the brain responsible for visual processing, can lead to a significant and sudden loss of vision in specific fields, often referred to as homonymous hemianopsia.

These conditions are well-established causes of visual field loss, making this choice the most accurate and relevant among the options given.
