Iris Cancer: A Rare but Serious Eye Condition

Iris cancer, also known as choroid melanoma, is a rare and serious form of eye cancer that affects the colored part of the eye, called the iris. It is a type of uveal melanoma, which accounts for approximately 5% of all uveal melanomas [12].

Symptoms and Signs

Iris cancer can show signs such as:

• A growing dark spot on the iris
• Change in the shape of the pupil (ectropion uveae)
• Deformity of the pupil
• Development of cataracts beneath the tumor
• Blood vessels within the tumor
• Secondary glaucoma

These symptoms may be accompanied by poor or blurry vision in one eye [3].

Diagnosis and Staging

Iris cancer can be diagnosed early if found in its early stages. The stage of intraocular melanoma of the iris is based on the size of the tumour, where the tumour is in the eye, and if it has spread outside of the eye [6].

Types and Frequency

Malignant melanomas generally present as solitary nodular lesions located in the lower half of the iris. They tend to be unilateral and can be associated with other primary sites such as breast or lung carcinomas [10]. Iris melanoma is the most common primary neoplasm of the iris, occurring more frequently in Caucasians with a light-colored iris versus non-Caucasians [12].

Treatment and Prognosis

While most uveal melanomas start in the choroid, a smaller number start in the iris. Melanomas in the iris most often grow slowly and don’t spread to other parts of the body. Treatment options include brachytherapy and surgery [14]. However, all forms of eye cancer are extremely rare, with uveal melanomas being one of the most common types.

Common Signs and Symptoms of Iris Cancer

Iris cancer, also known as melanoma, can be a serious condition that affects the colored part of the eye (iris). While it may not always cause noticeable symptoms in its early stages, there are several signs and symptoms to look out for.

• Vision changes: Blurry vision, double vision, or loss of peripheral vision can be indicative of iris cancer [1][2].
• Floaters: Seeing spots or squiggles drifting in the field of vision, also known as floaters, can be a symptom of iris cancer [3][4].
• Flashes of light: Experiencing flashes of light or seeing shadows in your vision can be a sign of iris cancer [5][6].
• Growing dark spot on the iris: A noticeable dark spot on the colored part of the eye (iris) can be an early sign of iris cancer [7][8].
• Change in pupil shape or size: Changes in the shape or size of the pupil can also indicate iris cancer [9][10].

It's essential to note that these symptoms can vary from person to person, and not everyone with iris cancer will experience all of them. If you're concerned about your eye health or notice any unusual changes, it's crucial to consult an eye care specialist for a proper evaluation.

Diagnostic Tests for Iris Cancer

Iris cancer, also known as melanoma, can be diagnosed using various tests and procedures. The following are some of the diagnostic tests that may be used to confirm a diagnosis of iris cancer:

• Imaging tests: These tests use sound waves, x-rays, or magnetic fields, or radioactive particles to create pictures of the inside of your body. They might be done for a number of reasons, including to rule out or diagnose eye cancer [1].
• Ultrasound: This test can reveal if the tumor is cystic or

Treatment Options for Iris Cancer

Iris cancer, also known as intraocular melanoma of the iris, can be treated using various methods. The most common treatment approaches include:

• Surgery: In some cases, surgery may be necessary to remove the tumor from the eye.
• Immunotherapy: Immunotherapy is a type of treatment that uses the body's immune system to fight cancer cells. It is often used in combination with other treatments.
• Targeted therapy: Targeted therapy involves using medications that specifically target and destroy cancer cells.
• Chemotherapy: Chemotherapy may be used to treat iris cancer, especially if it has spread to other parts of the body.

Specific Treatments for Iris Cancer

According to search results [3], intraocular melanoma of the iris is usually a small tumor that grows slowly and rarely spreads to other parts of the body. The treatment options mentioned in this result include surgery, radiotherapy, and chemotherapy.

Search result [4] mentions that the drug doctors use most often for treating eye cancer is methotrexate. This medication is typically given through regular injections over a period of time.

New Developments in Iris Cancer Treatment

A recent development in iris cancer treatment is the introduction of new drugs such as tebentafusp, which has been shown to help people live longer with uveal melanoma [6]. Additionally, targeted therapy and immunotherapy are also being explored as potential treatment options for this type of cancer.

Common Side Effects of Iris Cancer Treatment

It's worth noting that certain cancer treatments can cause eye-related side effects. Chemotherapy, immunotherapy, and hormone therapy are known to cause different eye problems, including inflammation and soreness in the eyelids [10]. Most of these side effects are temporary and can be managed with medication or by adjusting the treatment plan.

The differential diagnosis of iris cancer, also known as malignant melanoma of the iris, involves considering various conditions that can mimic or resemble the symptoms and characteristics of iris cancer.

Common Differential Diagnoses

• Iris pigment epithelial cyst: A benign growth that can appear similar to a tumor in the iris. [1]
• Iris stromal cyst: A type of cyst that can occur in the iris, often causing no symptoms or minimal vision problems. [15]
• Iris nevi: Benign growths on the iris that can be mistaken for melanoma. [5]
• Iris metastases: Cancer cells from other parts of the body that have spread to the iris. [10]
• Iris foreign body: A small object or particle that has become embedded in the iris, which can cause inflammation and mimic tumor-like symptoms. [4]

Other Conditions

• Primary iris cyst: A benign growth that can occur in the iris, often causing no symptoms or minimal vision problems. [2]
• Essential iris atrophy: A condition where the iris becomes thin and weak, leading to changes in its
