- Conjunctival tumors are malignant cancers that grow on the outer surface of the eye. The most common types of conjunctival tumors are squamous cell carcinoma, malignant melanoma, and lymphoma. Squamous cell carcinomas rarely metastasize, but can invade the area around the eye into the orbit and sinuses.

Choroidal Metastasis Most patients with metastasis have either a known primary cancer and/or metastatic tumors in other parts of their body. A careful medical history can uncover the signs or symptoms of these other cancers. If an eye cancer specialist suspects ocular metastasis, both eyes and orbits should be examined because ocular metastases can be both bilateral and/or multifocal.

- Retinoblastoma is a childhood disease. In general, most new cases of retinoblastoma are diagnosed before the age of 5. Children with retinoblastoma in both eyes are generally diagnosed at a younger age (mean = 13 to 15 months) than children with unilateral disease (mean = 24 months).The overall average age at diagnosis is 18 months.lthough the disease is very rare, retinoblastoma (RB) is the most common eye tumor in children, and the third most common cancer overall affecting children. Retinoblastoma is a disease that causes the growth of malignant tumors in the retinal cell layer of the eye.

Orbital Tumors An orbital tumor refers to any tumor located in the “orbit,” which is the bony socket in the front of the skull that contains the eye. The socket is a complicated structure that includes the eye itself along with muscles, nerves, and connective tissue. The socket is widest in the front and narrows toward the back, where the optic nerve leaves the socket and connects to the brain. Even a tiny tumor in this small, crowded space can cause significant symptoms and functional effects. Larger tumors can cause the eye to bulge forward and cause serious vision problems.

Eye cancer Melanoma is cancer that develops from pigment-producing cells called melanocytes. Most melanomas develop in the skin, but it's also possible for them to occur in other parts of the body, including the eye. Eye melanoma most commonly affects the eyeball.

- 1 If the tumor is in the cerebellum, where coordination is controlled, a person might have trouble with walking or other everyday functions, even eating.  Tumors in the back part of the brain, or around the pituitary gland, the optic nerve, or certain other cranial nerves can cause vision problems.

Key Statistics for Eye Cancer Both of these cancers start more often in other parts of the body. More than 9 out of 10 melanomas start in the skin, while most lymphomas begin in lymph nodes. For statistics on survival, see “ Eye cancer survival rates.”. Visit the American Cancer Society’s Cancer Statistics Center for more key statistics.

Lacrimal gland tumor Definition. A lacrimal gland tumor is a tumor in one of the glands that produce tears. The lacrimal glands are located under the outer part of each eyebrow. Lacrimal gland tumors can be harmless (benign) or cancerous (malignant). About half of lacrimal gland tumors are benign.

Uveal melanoma Tumors arise from the pigment cells (melanocytes) that reside within the uvea giving color to the eye. These melanocytes are distinct from the retinal pigment epithelium cells underlying the retina that do not form melanomas.

Eyelid Tumors in Dogs Overview of Canine Eyelid Tumors. The eyelid is a common site of tumor formation in dogs. Most eyelid tumors occur in middle-aged to older animals. The vast majority of eyelid tumors in the dog are benign. Canine eyelid tumors often originate spontaneously from the glands located within the eyelid margin.

- Cancers in the eye (intraocular cancers). Two types of cancers can be found in the eye. Primary intraocular cancers start inside the eyeball. In adults, melanoma is the most common primary intraocular cancer, followed by primary intraocular lymphoma.

Canine Eyelid Diseases 2. EYELID TUMORS. Older dogs commonly develop eyelid tumors (cancer). As in humans, cancer can be either benign or malignant. Fortunately, eyelid tumors in dogs are usually benign and do not spread to distant tissues. However, eyelid tumors do slowly or quickly grow, and can destroy the structure of the eyelid, in addition to rubbing on the eye.

Visual Problems due to Pituitary Tumors Patients with small pituitary tumors do not typically develop visual symptoms. However, if a pituitary tumor has grown larger (usually more than 1 cm), then a patient can develop visual loss in one or both eyes. One pattern of visual loss that characteristically occurs is reduced peripheral vision to both sides.

Introduction to Ocular Melanoma Melanoma can also occur in the thin lining over the white part of the eye (the conjunctiva) or on the eyelid, but this is very rare. OM tumors arise from the pigment cells (melanocytes) that give color to the eye. Formation of these tumors is quite rare and, as for many other forms of cancer, the exact cause is unknown.

- OPTIC NERVE GLIOMA is a tumor of the Glial cells that make up part of this vitally important nerve. These tumors are more common in childhood, and usually, are slow growing. It can reduce vision. Tumor excision is generally not undertaken, since it will lead to permanent loss of vision in that eye.

Retinoblastoma Retinoblastoma is a rare type of eye cancer that usually develops in early childhood, typically before the age of 5. This form of cancer develops in the retina, which is the specialized light-sensitive tissue at the back of the eye that detects light and color. In most children with retinoblastoma, the disease affects only one eye. However, one out of three children with retinoblastoma develops cancer in both eyes.
