Cancer of the eye

Cancer eyes

cancer of the eye photo eye cancer - rarely encountered a group of malignant tumors that develop in the tissues of the eye and its appendages.As a rule, these malignancies are classified according to the place of localization: conjunctiva, choroid, eye socket (orbit), the retina, the appendages of the eye (lacrimal gland and eyelid)

eye cancer - causes of

establish the cause can provokedevelopment of malignancy eye to this day have not managed that talks about the possibility of this pathological process in virtually any person.Despite this, it was noted that the development of eye cancer in some cases occurred in people living in adverse environmental conditions.In addition, it noted the hereditary tendency to develop this disease, as confirmed cases of this disease defeat of several generations of one family.There have been documented cases when the disease develops in the presence of HIV infection.Secondary swelling of the eye develops through the metastatic spread of malignant tumors of other


Another reason that according to most experts leads to the development of cancer is exposure to ultraviolet radiation.That is why people who have overcome three decades abroad, it is not recommended for a long time to be exposed to direct sunlight, and if this effect any reason still can not be avoided, then in the summer to use sunglasses with high quality glass

eye cancer - types

most common cancer affects the eyelid (from 50 to 80%), with a peak incidence between the ages of 55 to 75 years.In this case, the development of cancer is preceded by precancerous lesions such as senile keratosis, cutaneous horn, xeroderma pigmentosum, Bowen epithelioma.Much less (5-10% of cases) affects the conjunctiva, most common tumor progression observed in perilimbalnoy conjunctiva.Even more rarely, cancer affects the ciliary body, choroid, the iris of the eye and orbit.In the later stages of cancer of the orbit, the disease can spread to adjacent sinuses and skull.

following types of tumor eyes and appendages: sarcoma, melanoma, carcinoma, retinoblastoma.

Sarcoma mainly develops in the orbit of the eye.Its main symptom is considered to be the development of exophthalmos, which increases very quickly over a short period of time.The patient is disturbed mobility of the eyeball, there is pain and a sense of fullness and gradually atrophied optic nerve swells eyelid.Kaposi's eye is divided into several varieties: chondrosarcoma, fibrosarcoma, rhabdomyosarcoma, angiosarcoma sarcoma.

Melanoma is quite common cancer and is characterized by rapid progression and rapid metastasis to other organs.Melanoma most often develops in the iris, choroid and ciliary body.In the case of destruction of the iris appears constant eye irritation, developing secondary glaucoma, there is a fast-growing dark spots.Identification of a tumor of the ciliary body and the choroid presents certain difficulties as a result requires the use of special additional diagnostic equipment.Melanoma often affects the choroid, and the initial symptoms in this case can be completely absent.Patient anxiety is manifested only after the decline of the field and visual acuity, often worsening peripheral vision.

carcinoma is the most common malignant tumor of the eye (of 45 to 85% of all cases).Most often this disease affects women after fifty years.Carcinoma is divided into basal and squamous.

eyes Basal cell carcinoma most commonly affects the inner corner of the eye and / or lower eyelids.In case of delayed treatment to the doctor, the disease progresses fast enough, capturing the deepest parts of the century, paranasal sinuses, orbit and eyeball.Basal cell carcinoma is divided into the following forms: ulcerative, nodular, destructive and sclerotic surface.

Squamous cell carcinoma eyes is less dangerous to the patient's life, as more often than not provoke the emergence of metastases.In most cases, the tumor develops in the border area of ​​the epidermis and mucous membranes of the lower eyelid and / or inner corner of the eye.Initially, the skin of the century there is a small seal (has both an anchor and ulcerative form), which then increases with the rise in the central part of the crust, which in the case of attempts to remove bleeds.In some cases there may be a tumor invasion to sufficiently large dimensions and its transition to the cheek skin and conjunctivitis.Metastases may occur in the submandibular and cervical lymph nodes.

Retinoblastoma retina (diktyoma) tends to be hereditary and is most commonly diagnosed in children up to five years.Symptoms of retinoblastoma in children: the emergence of blindness and secondary glaucoma, strabismus, mydriasis.When light is reflected from the pupil of the tumor, it starts to shine whitish-yellow glow.The last stage of this form of cancer of the eye characterized by the development of exophthalmos, which manifests itself in a characteristic forward displacement of the eyeball.In the case of tumor invasion of the orbit and brain, eyeball may move toward

eye cancer - symptoms

eye Symptoms of cancer depend on the specific type of cancer.Cancer of the conjunctiva seen rapid growth of tumors that may visually look like a thick whitish film or remind nodules or growths.

Malignant tumor formation century manifested thickening and papilolmatoznyh dirty pink growths on the conjunctiva.At advanced stages of the disease in the century observed destructive plague may offset the eye.

lacrimal gland cancer manifests discomfort in the orbit and a strong swelling of the eyelids.In the later stages of the disease, a shift, and the omission of the eyeball limited his mobility.

cancer of the retina is stronger pain and progressive strabismus.In the later stages there is a detached retina and loss of vision.

Cancer Diagnosis eye is conducting a survey of the patient, complete medical history, examination of the eyeball, acuity and visual field.For a detailed examination of the fundus shows mandatory ophthalmoscopy.No less important is the study of US orbit and eyeball.However, the most informative method of diagnosis is computed tomography

eye cancer - treatment

eye cancer treatment is carried out using a complex combination of techniques that are matched to each patient is individual.Depending on the indication radiation therapy, chemotherapy, and if necessary, surgery.The main therapeutic goal - to save the patient's eyes and vision.Thanks to modern therapeutic techniques and timely treatment for the qualified help, according to the statistics today about 75% of patients manage to preserve vision.

When a large tumor in some cases, radiosurgery is used, which is irradiated tumors photons using a linear accelerator.In the case of a negative result, the possibility of removal of the eyeball with the subsequent installation of the prosthesis.

If diagnosed with a tumor of the orbit, most often performed to remove tumors radical surgery.In cancer of the iris is shown holding a partial resection of the iris of the eye.When diagnosed skin cancer century performed surgery followed by eyelid surgery.In the case of tumor metastasis to the lymph nodes shown holding lymphadenectomy.

When choroidal melanoma often, even several years after the treatment may develop secondary tumors.Therefore, even after apparent complete recovery need to undergo regular preventive examinations by an ophthalmologist.
