Ablepsia
Ablepsia (pronounced: ah-blep-see-uh) is a medical term that refers to a condition of total blindness.
Etymology
The term Ablepsia is derived from the Greek word "ablepsia" which means "blindness". It is composed of the prefix "a-" meaning "without" and "blepsis" meaning "sight".
Definition
Ablepsia is a complete loss of sight, resulting in total blindness. This condition can be caused by a variety of factors, including disease, injury, or genetic disorders. It is different from visual impairment or low vision, which refers to less severe vision loss.
Causes

- Disease: Certain diseases, such as glaucoma, macular degeneration, and diabetic retinopathy, can lead to ablepsia.
- Injury: Trauma to the eye or brain can result in ablepsia.
- Genetic disorders: Certain genetic conditions, such as Leber's congenital amaurosis, can cause ablepsia.

Treatment for ablepsia depends on the underlying cause. In some cases, treatment may not be possible. In other cases, treatment may involve surgery, medication, or vision rehabilitation.
