Eye neoplasms can affect all parts of the eye, and can be a benign tumor or a malignant tumor (cancer). Eye cancers can be primary (starts within the eye) or metastatic cancer (spread to the eye from another organ). The two most common cancers that spread to the eye from another organ are breast cancer and lung cancer. Other less common sites of origin include the prostate, kidney, thyroid, skin, colon and blood or bone marrow.

The most common eyelid tumor is called basal cell carcinoma. This tumor can grow around the eye but rarely spreads to other parts of the body. Other types of common eyelid cancers include squamous carcinoma, sebaceous carcinoma and malignant melanoma. The most common orbital malignancy is orbital lymphoma. This tumor can be diagnosed by biopsy with histopathologic and immune histochemical analysis. Most patients with orbital lymphoma can be offered chemotherapy or radiation therapy.

Orbital dermoid cysts are benign choristomas which are typically found at the junction of sutures, most commonly at the fronto-zygomatic suture. Large deep orbital dermoid cysts can cause pressure effects on the muscles and optic nerve, leading to diplopia and loss of vision.

Signs and Symptoms

• Melanomas (choroidal, ciliary body and uveal) - In the early stages there may be no symptoms (the person does not know there is a tumor until an ophthalmologist or optometrist looks into the eye with an ophthalmoscope during a routine test). As the tumor grows, symptoms can be blurred vision, decreased vision, double vision, eventual vision loss and if they continue to grow the tumor can break past the retina causing retinal detachment. Sometimes the tumor can be visible through the pupil.
• A nevus is a benign, freckle in the eye. These should be checked out and regular checks on the eye done to ensure it has not turned into a melanoma.
• Iris and conjuctival tumors (melanomas) - Present as a dark spot. Any spot which continues to grow on the iris and the conjunctiva should be checked out.
• Retinoblastoma - Strabismus (crossed eyes), a whitish or yellowish glow through the pupil, decreasing/loss of vision, sometimes the eye may be red and painful. Retinoblastoma can occur in one or both eyes. This tumor occurs in babies and young children. It is called RB for short. Check photographs, normal healthy eyes would have the red eye reflex, but a white/yellow dot instead of the red eye reflex can indicate a tumor or some other kind of eye disease. Any photos of a child/children which have a white/yellow dot instead of the red eye reflex should be evaluated by an eye doctor.

Optometry: Open Access Journal deals with eyes and related structures which includes such as vision, processing information related to vision. Optometrists are health professionals provide care related to vision. They give a clear idea related to diagnosis, treatment and management of vision. Optometry journal deals with medications, vision tests and abnormalities of eye.
