Any ocular tissues can develop a tumor during life. These tumors can be benign or malignant, and if malignant, may come from another location in the body (metástasis.) is important to differentiate metastatic tumors that originate in the ocular apparatus. All ocular tumors require a thorough evaluation by an ophthalmologist early.

EYELID TUMORS
The eyelid tumors are very common and appear as irregularities or "packages" that can be mistaken for other injuries such as a stye or chalazion. They are usually benign, but sometimes can be evil with great ability to spread both locally and remotely. The only way to determine for sure whether a tumor is malignant or benign tissue is examined under a microscope (biopsy.) Your ophthalmologist may suggest removing a portion of the tumor for this purpose, if the tumor is small, its total removal is performed.

CONJUNCTIVAL TUMORS
Conjunctival tumors affect the mucous membranes covering the white layer of the eye, the conjunctiva. These lesions typically appear as a dot or a small raised area on white background of the sclera. Malignant tumors are difficult to differentiate benign compared to well before any neoformation at this level, you need to go to the ophthalmologist to assess and suggest that its removal or irradiation.

EYE SPECIFIC TUMORS
Eye tumors are not common, but when they appear, especially at intraocular are difficult to diagnose. Sometimes a character can have severe malignant melanomas and retinoblastomas or for children, requiring not only shifts but removing the complete enucleation of the eye. When a tumor is diagnosed as benign, in most cases, only necessary observation or is a vascular tumor, can be performed a laser treatment to remove it.

The most malignant ocular tumor is melanoma and usually occurs in middle-aged or elderly. Approximately half of the cases of these tumors metastasize (spread) to other parts of the body where they grow despite aggressive treatment, may lead to death.

Since there is little scientific evidence that any treatment, including surgery, radiation or removal of the eye, affects the outcome, the treatment of melanoma is subject to controversy. Through various studies are evaluating the different methods of treatment, but it will be several years before the results are known. At present, the proton accelerators radiation has shown greater efficacy in the survival time therefore is the technique most widely used treatment at this time.

A rare tumor genetically determined that can threaten the patient's life, is retinoblastoma, which may appear in young children. For the survival of the baby or child can be made without visual abnormalities or defects, should be considered early by an ophthalmologist for immediate diagnosis and treatment. If the tumor is large or affects both eyes may require the removal of an eye, treated with radiotherapy, chemotherapy or a combination of the two. Retinoblastoma can occur in other family members, so the examination and genetic counseling are highly recommended in these cases.

ORBITAL TUMORS
The tumors may originate in the orbit, near the eye, moving the eyeball and causing decreased vision or double vision determining. Diagnosis usually requires a thorough evaluation often includes radiological examination and blood tests. Treatment methods may include radiation therapy or surgery to remove the tumor.


WHY EXAMINATION BY AN OPHTHALMOLOGIST ARE IMPORTANT FOR EVERYONE?
The eye disease can occur at any age. Certain eye diseases cause no symptoms until occur and changes occur. The blindness is preventable if diagnosed and treated in early regular medical examinations by an ophthalmologist. Why an ophthalmologist ?, because an ophthalmologist (MD) is the only specialist that can provide a complete eye care, both optical and medical or surgical. It is advisable to perform periodic reviews every one or two years, especially after age 40, although no ocular symptoms appear.
