Managing Ocular Side Effects of Chemotherapy and Radiation Therapy: How Brookside Optometric Group Can Help

Breast cancer treatment can be a challenging and emotional journey. While chemotherapy and radiation therapy are effective ways to fight cancer, they can also cause side effects, including ocular complications. At Brookside Optometric Group, our goal is to help you maintain optimal eye health during and after your cancer treatment. In this article, we'll explore the common eye-related side effects of chemotherapy and radiation therapy, and discuss how our experienced optometrists can help you monitor, manage, or prevent these problems.

Chemotherapy and radiation therapy are powerful cancer treatments that work by targeting rapidly dividing cells, such as cancer cells. However, these treatments can also affect healthy cells, including those in the eyes, leading to various vision conditions and side effects.

Common Side Effects of Cancer Treatments

1. Dry eyes: Chemotherapy can affect the function of the lacrimal glands, responsible for producing tears, leading to a reduced tear production. This lack of lubrication can cause discomfort, itching, and blurred vision.
2. Watery eyes (epiphora): Chemotherapy and radiation therapy can irritate the eyes, leading to inflammation and overproduction of tears. Additionally, these treatments can cause scarring or blockage of the tear drainage system, causing tears to overflow.
3. Conjunctivitis: Chemotherapy drugs can cause inflammation or infection of the conjunctiva, the thin membrane covering the white part of the eye and the inner surface of the eyelids. This results in redness, swelling, and discharge.
4. Changes in vision: Some chemotherapy drugs can affect the muscles controlling the eye's lens, leading to difficulty in focusing or fluctuations in vision. Additionally, chemotherapy-induced peripheral neuropathy can impact the nerves responsible for transmitting visual information, causing blurred or double vision.

Rarer Side Effects of Cancer Treatments

1. Cataracts: Radiation therapy, particularly when directed near the eyes, can cause damage to the lens, leading to the formation of cataracts. Cataracts are characterized by the clouding of the lens, which results in blurred or hazy vision.
2. Glaucoma: Radiation therapy can cause damage to the trabecular meshwork, the structure responsible for draining the aqueous humor from the eye. This damage can lead to increased eye pressure, which in turn can damage the optic nerve and cause vision loss.
3. Retinopathy: Some chemotherapy drugs, such as those in the anti-vascular endothelial growth factor (anti-VEGF) class, can cause damage to the blood vessels in the retina. This damage can lead to fluid leakage, swelling, and vision disturbances.
4. Optic neuropathy: Chemotherapy and radiation therapy can cause inflammation, damage, or compression of the optic nerve, potentially leading to vision loss. Optic neuropathy may present as blurry or dim vision, loss of color vision, or visual field defects.

It is essential to note that not all patients undergoing chemotherapy and radiation therapy will experience these side effects. The likelihood of developing these ocular complications depends on various factors, including the type of cancer, the specific chemotherapy drugs used, the radiation dose, and the individual patient's overall health.
