Retinal Cancer: A Rare but Serious Condition

Retinal cancer, also known as intraocular cancer, is a rare type of cancer that affects the eye. It starts in the cells inside the eyeball and can spread to nearby tissues.

• Types of Retinal Cancer: There are several types of retinal cancer, including melanoma (a rare cancer that begins in cells that produce pigment), lymphoma (a type of blood cancer), and retinoblastoma (a cancer that starts in the retina).
• Symptoms: The symptoms of retinal cancer can vary depending on the type and stage of the disease. Common symptoms include:
  • Squinting
  • Unusual glint in eye
  • Retinal tumor
  • White looking pupil (Leukokoria)
  • Crossed eyes (Strabismus)
  • Vision loss
• Causes: The exact cause of retinal cancer is not known, but it is believed to be related to genetic mutations and exposure to certain environmental factors.
• Treatment Options: Treatment for retinal cancer depends on the type and stage of the disease. Common treatments include brachytherapy (a type of radiation therapy), surgery, and chemotherapy.

Common Signs and Symptoms of Retinal Cancer

Retinal cancer, also known as eye cancer, can manifest in various ways, making it essential to be aware of the possible symptoms. Here are some common signs and symptoms associated with retinal cancer:

• Vision Loss: The most common symptom of retinal cancer is painless vision loss [5]. This can occur suddenly or gradually over time.
• Floaters and Flashes: Floaters (spots or squiggles drifting in the field of vision) or flashes of light are other symptoms that may indicate retinal cancer [1][3].
• Blurred Vision: Blurry vision is a common symptom, which can be caused by the tumor affecting the retina's ability to transmit visual information [5].
• Shadows and Wiggly Lines: Shadows, flashes of light, or wiggly lines in your vision may also be signs of retinal cancer [2][8].
• Dark Patch in the Eye: A dark patch in the eye that is getting bigger can be a symptom of retinal cancer [4][8].
• Bulging Eye: In some cases, bulging of one eye can occur due to the tumor growing and putting pressure on the surrounding tissues [6].

It's essential to note that not all people with retinal cancer will experience these symptoms, and some may have additional symptoms not listed here. If you're concerned about your vision or suspect you might be experiencing symptoms related to retinal cancer, consult a medical professional for proper evaluation and diagnosis.

Diagnostic Tests for Retinal Cancer

Retinal cancer, also known as intraocular melanoma, can be diagnosed using various tests and exams. Here are some of the common diagnostic tests used to detect retinal cancer:

• Eye Exam: A comprehensive eye exam by an ophthalmologist is usually the first step in diagnosing retinal cancer. The doctor may use a dilated pupil examination to look for any abnormalities in the retina.
• Ultrasound Imaging: Ultrasound imaging uses high-frequency sound waves to create images of the inside of the eye. This test can help detect tumors or other abnormalities in the retina.
• Optical Coherence Tomography (OCT) Scan: An OCT scan is a non-invasive imaging test that uses low-coherence interferometry to produce high-resolution images of the retina. It can help detect retinal cancer by showing any changes in the retina's structure.
• Fluorescein Angiogram: A fluorescein angiogram is an imaging test that uses a fluorescent dye to highlight blood vessels in the retina. This test can help detect any abnormalities in the blood vessels, which may indicate retinal cancer.
• Biopsy: In some cases, a biopsy may be necessary to confirm the diagnosis of retinal cancer. A biopsy involves removing a small sample of tissue from the eye for examination under a microscope.

Early Detection and Diagnosis

Early detection and diagnosis of retinal cancer are crucial in treating the condition effectively. According to [1], early diagnosis can improve treatment outcomes and reduce the risk of complications.

Tests Used by Specialists

Specialists may use various tests, including:

• Eye Examination: A thorough eye examination is usually the first step in diagnosing retinal cancer.
• Ultrasound Scan: An ultrasound scan can help detect tumors or other abnormalities in the retina.
• Fluorescein Angiogram: A fluorescein angiogram can help detect any changes in the blood vessels, which may indicate retinal cancer.

Treatment Options for Retinal Cancer

Retinal cancer, also known as intraocular retinoblastoma, can be treated with various drug therapies. While surgery and radiotherapy are common treatments, chemotherapy is often used to shrink tumors and prevent their growth.

• Chemotherapy: Chemotherapy involves using drugs to kill cancer cells. This treatment is commonly used in combination with other therapies, such as surgery or radiation therapy. Chemotherapy can be administered orally or through injections into the eye.
  • Methotrexate is a common chemotherapy drug used to treat retinal cancer [2].
• Targeted Therapy: Targeted therapy involves using drugs that specifically target cancer cells. These drugs work by blocking certain proteins that help cancer cells grow and divide.
  • Bevacizumab (Avastin) and ranibizumab (Lucentis) are targeted therapies used to treat retinal cancer [4].
• Immunotherapy: Immunotherapy involves using the body's immune system to fight cancer. This treatment can be used in combination with other therapies, such as chemotherapy or radiation therapy.
  • Novel immunotherapies, such as oncolytic viruses and checkpoint inhibitors, are being explored for the treatment of intraocular retinoblastoma [6].

Combination Therapy

In many cases, a combination of drug therapies is used to treat retinal cancer. This approach can be more effective than using a single therapy.

• Carboplatin, vincristine, and etoposide: A standard combination chemotherapy regimen for retinal cancer involves the use of carboplatin, vincristine, and etoposide [3].
• Tebentafusp: Tebentafusp is a systemic therapy that has been shown to improve survival rates in patients with uveal melanoma, a type of eye cancer that can spread to the retina [7].

Other Treatment Options

In addition to drug therapies, other treatment options for retinal cancer include surgery and radiotherapy.

• Surgery: Surgery may be used to remove tumors or affected parts of the eye.
• Radiotherapy: Radiotherapy involves using high-energy radiation to kill cancer cells. This treatment can be used in combination with chemotherapy or as a standalone therapy.

It's essential to note that each patient's situation is unique, and the most effective treatment plan will depend on individual factors, such as the stage of the disease and overall health.

The differential diagnosis for retinal cancer, also known as retinoblastoma, includes several conditions that can present with similar symptoms.

Common Differential Diagnoses

• Non-paraneoplastic autoimmune retinopathy: This is a condition where the immune system attacks the retina, leading to vision loss and other symptoms. It is often associated with systemic autoimmune diseases.
• White dot syndrome spectrum disorders: These are conditions characterized by white or yellowish lesions on the retina, which can be mistaken for retinal cancer.
• Congenital hypertrophy of retinal pigment epithelium (CHRPE): This is a benign condition where there is an overgrowth of retinal pigment cells. While it can appear similar to retinoblastoma, it is not cancerous.

Other Differential Diagnoses

• Leukocoria: Also known as "cat's eye reflex," this is a white reflection from the retina that can be seen in infants and young children. While it can be a sign of retinal cancer, it can also be caused by other conditions such as cataracts or congenital anomalies.
• Iris melanoma: This is a type of cancer that affects the iris, which can present with similar symptoms to retinoblastoma.

Key Diagnostic Features

• The presence of an unusually high number of hypertrophic retinal pigment epithelial lesions (CHRPE) and a typical teardrop appearance should clue the clinician in to a possible diagnosis of Gardner’s syndrome and the need for referral to a gastroenterologist [3].
• Fluorescein angiography is the most informative diagnostic study owing to the high degree of vascularity in these tumors [8].
