In 1990, the causes of amaurosis fugax were better refined by the Amaurosis Fugax Study Group, which has defined five distinct classes of transient monocular blindness based on their supposed cause: embolic, hemodynamic, ocular, neurologic, and idiopathic (or "no cause identified"). [8]
Leber's congenital amaurosis (LCA) is the most severe and earliest of the inherited retinal dystrophies that cause congenital blindness. It has an incidence of 2-3 per 100,000 births and accounts for 10-18% of cases of congenital blindness among children in blind institutes and 5% of all retinal dystrophies, a figure that is likely to be greater in countries with a greater percentage of ...
Monocular vision is known as seeing and using only one eye in the human species. Depth perception in monocular vision is reduced compared to binocular vision, but still is active primarily due to accommodation of the eye and motion parallax. The word monocular comes from the Greek root, mono for single, and the Latin root, oculus for eye.
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception.In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking.

People taking Ozempic and Wegovy may be at increased risk of developing a debilitating eye condition that can cause irreversible vision loss, a study published in JAMA Ophthalmology finds.
Currently there is no treatment for this condition, but, it is usually self limiting. [1] Systemic administration of corticosteroids may be advised. [2] Even if the disease is resolved, the enlarged blind spot usually does not return to normal. [5]

Cortical blindness refers to any partial or complete visual deficit that is caused by damage to the visual cortex in the occipital lobe. Unilateral lesions can lead to homonymous hemianopias and scotomas. Bilateral lesions can cause complete cortical blindness and can sometimes be accompanied by a condition called Anton-Babinski syndrome. [26]
