Tumors of the eye

Medicine1


What are they?

Tumors of the eye can be benign (for example, birthmarks, angiomas, neurinomas and adenomas) and malignant.

Tumors of the inner and middle shells of the eye

The eye shells cover the eyeball with three layers. The inner layer covering the vitreous is the inner shell of the eyeball (retina). Between the inner and outer (fibrous) membranes of the eye is the middle shell, consisting of the iris, ciliary body and vascular membrane.

The most common tumor is the inner shell of the eye - retinoblastoma. It has a malignant character and appears already in the first-second year of the life of the child. Parents first of all notice that the fundus of the child seems gray-yellow or gray-red. Through the dilated pupil, the color of the fundus is clearly visible. Malignant and also quite common - it is a tumor of the middle shell of the eye - melanoblastoma. Increasing in size, it exerts pressure on the inner shell of the eye (retina) and the vitreous body. In comparison with other malignant formations, melanoblastoma grows slowly, so general ailments are manifested much later. When diagnosed melanoblastoma is difficult to help something.

Tumors of the orbit

Although these neoplasms are not classified as eye tumors, they always cause eye and vision problems and make up about a quarter of all tumors in children. As the tumor grows, the eyeball shifts forward, protrudes out of the orbit, and the eyelashes appear (exophthalmos). They can be benign or malignant.

Symptoms

Retinoblastoma:

  • Fixed dilated pupil.
  • White-yellow glow of the pupil.
  • Strabismus.

Tumor of the orbit:

  • Reduced mobility of the eyeball.
  • Inability to completely close the eye.
  • Exophthalmos - protrusion of the eyeball from the orbit.
  • Edema of the eyelids.

Causes

The appearance of eye tumors, as in other cases of malignant tumors, may be influenced by several different factors simultaneously. The cause of this pathology may be heredity, but the appearance of a tumor can provoke and environmental factors, for example, radioactive radiation or carcinogenic substances (substances that contribute to the occurrence of malignant tumors).

Treatment

Tumors are usually removed surgically. When malignant tumors of the retina or the middle shell of the eye (retinoblastoma, melanoblastoma) occur, the eye sometimes needs to be removed to save the patient's life. After the operation, laser therapy, chemotherapy and irradiation are applied.

To be engaged in self-treatment of tumoral diseases with the help of traditional medicine can be dangerous for life! With early diagnosis of the disease, there is a high probability of recovery. Therefore, it is extremely important to consult a doctor when the first symptoms of the disease appear.

The doctor will examine the fundus with the help of an ophthalmoscope. Often, even with a primary examination in appearance, one can learn a lot about the tumor.

Course of the disease

Melanoblastoma and retinoblastoma metastasize. In the absence of treatment, a fatal outcome is inevitable. Melanoblastoma can recur even after 20 years after removal of the underlying tumor. For this reason, after the operation, it is necessary to regularly undergo preventive examinations with the attending physician.

In connection with the possibility of the appearance of retinoblastoma in any child with strabismus, it is necessary to check the fundus. With early diagnosis of this disease, treatment is more effective.
