7.Chronic Progressive External Ophthalmoplegia (CPEO)
You can inherit genes that cause the muscles in and around your eye to get weak or stop working. It could start anywhere from age 18 to 40. It can affect one or both eyes. You may find it hard to swallow or you might feel that muscles all over your body are weak, especially after you exercise. There’s no cure, but surgery can correct droopy eyelids and other symptoms.
8.Anisocoria
Your pupils could be different sizes. About 1 in 5 people who have this don’t have any other health conditions along with it. Sometimes it signals a rare nerve problem. Horner’s syndrome is marked by one much smaller pupil, a droopy upper lid, an eyeball sunken into its socket, and a lack of facial sweat on just one side of the face. If a change in your pupil size happens suddenly, call your doctor immediately or go to the emergency room. In Adie syndrome, which usually doesn’t require treatment, one pupil is always open and barely responds to light. Some drugs like scopolamine patches for sea sickness can also cause one pupil to dilate if the medicine gets in the eye.
