Optic Atrophy Treatment in Nigeria: causes seen locally and how they are managed
Optic atrophy has many causes, and some are particularly relevant in West Africa. This page explains how the cause is found and what can be done about it.
Why the cause matters so much
A pale optic disc is the end point of many different problems. Finding the cause is what decides whether further loss can be prevented.
In Nigeria, doctors keep several causes in mind: nerve inflammation, river blindness, nutritional neuropathy linked to heavy cassava diets, side effects of drugs such as ethambutol or quinine, head injury, and growths pressing on the nerve.
Questions your doctor will ask
Your history guides the tests.
- Where have you lived or worked?Rural riverside areas raise suspicion of onchocerciasis.
- What medicines have you taken?Tuberculosis and malaria drugs can affect the nerve.
- What is your usual diet?Poor protein and heavy cassava can contribute.
- Any head injury or headaches?Points towards trauma or pressure.
