What eye problems might be associated with cancer treatment

Some cancer treatments may cause problems with your eyes, such as conjunctivitis, cataracts, dry eyes, photophobia and watery eyes.

Conjunctivitis: This condition, also known as “pink eye”, is caused by a viral or bacterial infection, or an allergic reaction. Chemotherapy drugs tend to suppress your immune system, making you more susceptible to infection.

Cataracts: Cataracts are a cloudy area in the lens of your eye that prevents light from passing through. They are painless, but do lead to a progressive loss of vision. Cataracts usually occur in one eye and won’t spread to the other.

Dry eyes: Your eyes will feel dry if you are not producing enough tears, or if your tears are lacking an important chemical involved in lubricating your eyes.

Photophobia: Sensitivity to light is called photophobia. This condition causes pain in your eyes when you move from a dark space to a light one, such as going outside during the daytime.

Watery eyes: Some drugs cause you to produce too many tears, leading to watery eyes.
