What is Eye Cancer ?

Eye cancer, medically known as ocular cancer, is a condition in which cells grow uncontrollably within the eye or its surrounding tissues. It occurs less frequently than other forms of cancer, but it can lead to vision problems that need immediate treatment to stop their spread to other body regions.

The condition may occur in different parts of the eye, including:

• The eyelid
• The conjunctiva, or a thin membrane that covers the white of the eye
• The uvea (middle eye layer) that contains the iris, ciliary body, and choroid
• The retina
• The optic nerve
• The orbit, which refers to the tissues that surround the eyeball

What are the most Common types of Eye Cancer ?

In Adults

1. Uveal melanoma
2. Intraocular lymphoma
3. Conjunctival melanoma
4. Orbital tumors

In Children

• Retinoblastoma, which represents the most frequent eye cancer found in children

Eye cancers develop from two different sources, as some start in the eye as primary eye cancer and others emerge through cancer cells that migrate to the eye from other body regions as secondary or metastatic eye cancer. Breast and lung cancers remain the primary reasons why patients develop eye metastasis.

Early vision preservation requires both specialized treatment and early detection.

What are the Symptoms and Causes of Eye Cancer?

Symptoms

The tumor location and its size determine the specific symptoms that will appear. Some eye cancers may not cause noticeable symptoms in early stages and may be detected during routine eye examinations.

Common symptoms the patient has may include:

• Difficulty seeing clearly or their vision becomes worse.
• Sudden vision changes
• Sees light flares
• Spots or lines that float in their vision
• Dark spot on their iris
• The patient experiences one eye bulging out.
• Develops redness or swelling
• Experiences less common eye pain
• They lose their ability to see things outside their central field of vision.
• The patient has a white reflection in their pupil, which is especially common in children with retinoblastoma.

The following are the signs or symptoms that may show a medical emergency in children:

• Leukocoria refers to a white glow in the pupil when a flash is used to photograph someone.
• Crossed eyes (strabismus)
• Poor vision
• The patient shows an expanded eye appearance.

Advanced cases may present with:

• Headaches
• Swelling around the eye
• Symptoms that indicate disease progression with liver involvement in melanoma.

Causes

The exact reason or cause of most eye cancers is not fully understood. Cancer develops when genetic mutations occur, leading to the formation of abnormal cells that grow unchecked.

The following factors increase the risk of developing uveal melanoma in the patient:

• Light-colored eyes.
• Excessive UV exposure.
• Certain genetic syndromes.
• Family history of retinoblastoma.
• Increasing age is associated with adult ocular melanoma.
• An immunocompromised state, leading to the development of intraocular lymphoma.

The RB1 gene mutation serves as the primary cause of retinoblastoma. Some children inherit this mutation while others develop it spontaneously.

What are the Main Types of Eye Cancer?

1. Uveal Melanoma
   This is the most common primary eye cancer in adults. The disease occurs when melanocytes proliferate in the uvea. The choroid represents the area where most cases manifest, and the liver is the primary organ affected by this disease.
2. Retinoblastoma
   It is most common in children under five years of age. The disease starts in retinal cells. The disease requires early detection because it becomes curable when patients receive swift treatment.
3. Conjunctival Melanoma
   The disease occurs when malignant cells develop in the conjunctiva. The disease presents as a pigmented skin lesion on the surface of the eye.
4. Intraocular Lymphoma
   A rare type of non-Hodgkin lymphoma that affects the eye. The condition frequently accompanies central nervous system lymphoma.
5. Orbital & Eyelid Cancers
   The cancerous tumors include basal cell carcinoma, squamous cell carcinoma, and various uncommon tumors.

How is Eye Cancer Diagnosed and Tested ?

Early detection significantly improves outcomes.

Comprehensive Eye Examination

An ophthalmologist can conduct a dilated eye exam, including a fundoscopy and a slit-lamp examination. The ophthalmologist conducts an indirect ophthalmoscopy examination. The tests help medical practitioners visualize tumors within the eye.

Imaging Tests

The medical facilities are used:

• Ocular ultrasound
• Optical coherence tomography
• MRI of the orbit and brain
• CT scan
• PET-CT with spreading suspicion.

Medical facilities use these tools to evaluate tumor size and the extent of spread.

Fluorescein Angiography

The process examines the retina's blood vessels and identifies abnormal tumor blood flow.

Biopsy

Clinicians use a biopsy process to confirm diagnosis in most cases, except when they suspect lymphoma. The medical field uses imaging features to diagnose most cases of intraocular melanoma without performing a biopsy.

Genetic Testing

The process of genetic testing will evaluate for the RB1 mutation in patients who have retinoblastoma.

Staging

The medical professionals determine staging through the following assessments:

• Tumor size
• Location of the tumor
• Whether nearby structures have been affected by the tumor
• Whether the tumor has impacted the lymph nodes
• If the malignant growth or tumor has spread to the lymph nodes.

Advanced imaging helps doctors determine whether cancer has reached the liver, lungs, and brain.

How is Eye Cancer Treated and Managed?

Treatment depends on:

• Type of eye cancer
• Tumor size
• Location
• Whether vision can be preserved
• Patient's age
• Spread of disease

A multidisciplinary team approach is essential.

Surgery

Surgery may involve:

• Local tumor removal
• Partial eye removal
• Complete removal of the eye through enucleation
• The surgical procedure of orbital exenteration, which removes the eye and adjacent tissues in advanced cases

Enucleation is performed when the tumor is large and vision cannot be preserved.

Prosthetic eye placement restores appearance after the eye is removed.

Radiation Therapy

Radiation is commonly used to treat eye cancers. The treatment methods include:

• Brachytherapy (plaque radiation)
• External beam radiation
• Proton beam therapy

The small radioactive plaque used for brachytherapy is positioned close to the tumor site.

Radiation helps preserve the eye in many cases.

Laser Therapy

Used for small tumors. The treatment methods include:

• Transpupillary thermotherapy (TTT)
• Laser photocoagulation

The procedure is often used in combination with various treatment methods.

Chemotherapy

Chemotherapy may be:

• Systemic (through IV)
• Intra-arterial (directly into the eye artery)
• Intravitreal (injected into the eye)

The chemotherapy treatment for retinoblastoma reduces tumor size and prevents the need for eye removal.

Immunotherapy & Targeted Therapy

For advanced melanoma:

• Immune checkpoint inhibitors
• Targeted therapy drugs

The treatments target both metastatic and advanced disease.

Treatment for Intraocular Lymphoma

The treatment methods include:

• Chemotherapy
• Radiation
• Intravitreal injections

The procedure is usually performed alongside neuro-oncology treatments.

What are the Complications of Eye Cancer Treatment?

The treatment may cause these side effects:

• Vision loss
• Dry eye
• Cataract formation
• Radiation retinopathy
• Cosmetic changes
• Emotional impact

Health professionals need to conduct long-term supervision of the patient.

What is Outlook / Prognosis for Eye Cancer ?

Prognosis depends on:

• Type of tumor
• Stage of diagnosis
• Patient age
• Cancer spread

Uveal Melanoma

Small tumors have good local control rates. However, metastatic risk remains.

Retinoblastoma

Early-stage disease has survival rates above 95% with proper treatment.

Intraocular Lymphoma

Prognosis depends on CNS involvement.

The follow-up process includes:

• Eye examinations
• Liver imaging (for melanoma)
• The brain imaging procedure, which is conducted when necessary
• Genetic counseling (for hereditary retinoblastoma)

The patient has a better chance of survival and maintaining vision with early medical intervention.
