- Corneal ulcers. This is caused by a viral or bacterial infection and appears on the eye’s outer covering.
- Uveitis. This occurs when the uvea, iris, choroid, and the ciliary body get inflamed and is associated as an autoimmune disorder and contributed by infection and toxin exposure.
- Acute glaucoma. This is a sudden increase in pressure brought to the eyes that can be severely painful and can lead to vision problems.
- Scratches in the cornea caused by extensive use of contact lenses.
