What eye diseases could cause my double vision?

Double vision, also known as Diplopia, can be a symptom of various eye conditions. Some common eye diseases that can cause double vision include:

- Strabismus (Crossed Eyes): This condition occurs when the eyes are not properly aligned, causing one eye to look inward or outward.

- Amblyopia (Lazy Eye): This is a condition in which one eye is weaker than the other, resulting in decreased vision and possible double vision.

- Nystagmus: This is a condition characterized by involuntary rapid eye movements, which can lead to double vision.

- Ptosis (Droopy Eyelid): When the eyelid droops and covers part of the pupil, it can interfere with vision and cause double vision.

- Thyroid Eye Disease: This is an autoimmune condition affecting the thyroid gland, which can cause the eye muscles to become weak or inflamed leading to double vision.

- Cataracts: Advanced cataracts can cause clouding of the eye's lens, disrupting the eye's ability to focus, and potentially leading to double vision.

- Corneal Diseases: Certain corneal conditions such as corneal ulcers, scarring or a keratoconus (a thinning of the cornea) can cause double vision by distorting the incoming light.

- Macular Degeneration: This age-related condition can lead to double vision in some individuals, particularly those with advanced macular degeneration.

- Optic Nerve Damage: Damage to the optic nerve caused by conditions like glaucoma or optic neuritis can result in double vision.

- Myasthenia Gravis: This neuromuscular disorder can cause weakness in the eye muscles, contributing to double vision.

It's essential to consult an eye doctor (ophthalmologist or optometrist) if you experience double vision or any sudden changes in your vision. The cause of the double vision can be determined through a comprehensive eye exam, which might involve tests such as a visual acuity test, eye muscle coordination tests, and imaging studies. Based on the underlying cause, appropriate treatment can be recommended to manage or correct the double vision.
