What is escotomas?

Escotomas are defined as areas of vision loss or blindness within someone's visual field. They can be caused by a number of different factors, including migraine headaches, optic nerve problems, retinal damage, and brain injuries or diseases. Depending on the cause and severity of the condition, escotomas may be temporary or permanent. Some people may experience partial or incomplete losses of vision, while others may have complete blindness in certain areas of their visual field. Treatment options for escotomas may include medication, surgery, or vision rehabilitation therapy.
