There are different types of blindness, such as partial blindness, low visual problems, light perception cases, and total blindness. Among the worst ailments brought about by eye and visual cortex damage, total blindness is top on the list. Total blindness is an ailment in which a person has no functional vision whatsoever.health

This usually results in serious injuries to the eyes, the optic nerves, and a certain portion of the human brain called the functional visual cortex. The damages that have left the eyes beyond repair can be treated with a surgical operation, which replaces the eyes with a new pair. Now, the effectiveness of this operation is dependent on the age of the person at the time the damage was inflicted to his eyes. You see, the functional visual cortex located on the human brain has not properly developed yet if the injury was acquired before the age of three, and in some cases, five. But for persons above this age requirement, treatment through such a surgical process is highly advised by medical professionals.

This case has also been true to those with injuries inflicted on the optic nerves. The optic nerves relay the electronic impulses sent by the eyes to the actual visual cortex located on the human brain. An improperly functioning set of optic nerves would just jumble the impulses into a jargon of unintelligible gibberish, or it may not even reach the functional visual cortex for that matter. With this, the actual visual cortex does not properly receive such electronic signals, let alone actually reach it, and this is one of the main reasons for total blindness.
