Swelling in the eye
Swelling in the eyeis a rather rare malignant neoplasm, which develops practically from all the internal tissues. To classify such lesions, oncology is divided by their location: cancer of the eyelid, retina, orbit and conjunctiva.
Tumor on the eye - the causes of education
To date, there is no reliable cause of eye oncology. Doctors share several risk factors that promote the development of mutations at the cellular level, the accumulation of which can cause the formation of a malignant neoplasm, that is, a tumor on the eye:
- negative environmental factors of the environment;
- genetic predisposition. The presence of a cancerous eye disease in direct relatives several times increases the likelihood of malignant degeneration of the internal tissues;
- systemic immunity reduction. Persistent inhibition of the protective abilities of the body occurs in patients with HIV infection;
- Oncology of the eye can also be the result of metastasis;
- exposure to ultraviolet and ionizing radiation.
Tumors on the eye - classification and description
Tumor on the eyelidis diagnosed in 80% of all clinical cases. The most susceptible category of patients are people aged 50-70 years. The disease is usually preceded by precancerous conditions (Bowen epithelioma, skin horn, senile keratosis).
Depending on the histological structure, the ocular tumors are divided into:
- Squamous cell carcinoma.Tumor on the lower eyelidor in the inner eye angle in the form of a dense knotty compaction, which is often ulcerated with the formation of epidermal crusts in the central part of the lesion. For the squamous cell form of cancer, the extensive growth of pathological tissues and the almost complete absence of metastases are characteristic.
- Basal cell carcinoma. The disease proceeds extremely aggressively with the formation of early metastases. It begins with the formation on the eye century of the red color of the seal, which rapidly increases in depth into the affected tissues. Gradually, an ulcer with bleeding edges forms in the central part of the cancer node. In later stages, oncology captures almost all the structural parts of the eye.
This is a common tumor, which is characterized by lightning with the formation of multiple metastases already at the initial stage of cancerous growth. In most cases, malignant neoplasm is localized in the ciliary body and iris. Melanoma cancer of the eye at the beginning of its growth has the form of a pigmented spot.
Tumor in the upper eyelid, which rapidly increases in size, disrupting the motor function of the eye, has pronounced pain sensations and atrophy of the optic nerve.
Symptoms of cancer on the eye
The development of signs of ophthalmologic oncology depends on the specific type of cancer. So, malignant neoplasms of conjunctiva have the form of dark red growth, which has a tuberous surface. Tumors of the eyelids are characterized by the formation of pigmented seals with bleeding ulcers.
Almost all kinds of malignant lesions are characterized by the presence of intense pain syndrome, impaired visual function and inflammatory swelling of soft tissues.
Diagnosis of ocular tumors
To determine the diagnosis, the ophthalmologist first of all finds out the history of the disease and collects an anamnesis of the disease. In the future, the patient is visual and instrumental examination of the eye, determining the severity and field of vision and diagnosed the condition of the full-body bottom.
Additional methods of research are:
- Ultrasound examination of a full-time apple, which allows to determine the presence of a tumor and its boundaries.
- Computer and magnetic resonance imaging. These diagnostic methods are necessary for studying the structure of a cancerous tumor and the extent of pathology.
- Radiography. Conducting a radiological study indicates a possible existence of a metastatic lesion of bone tissue.
Tumor on the eye - how to treat?
The modern approach to oncological therapy includes three basic principles:
- The maximum possible preservation of the visual function.
- Stabilization of malignant process.
- Radical removal of cancerous tissue.
An organ-preserving operation is performed in the early stages of oncology. Such surgical intervention is carried out with the help of laser technology. A doctor under the control of a computer cuts out cancerous tissues.
Anti-cancer surgery also uses techniques such as cryodistruction (deep freezing of cancer tissues) and thermal therapy (removal of the tumor with the help of thermal energy).
Cancers that have undergone laser removal require radiotherapy in the postoperative period to prevent recurrence of the disease.
Tumor on the eye of the last stage (with extensive lesion of the internal bottom) ophthalmologists are recommended to radically remove (removal of the ocnita with subsequent chemotherapy). The purpose of the use of cytostatic agents is the systematic destruction of cancer cells. Such therapy is carried out in several stages and requires an individual approach to the selection of a course of chemotherapeutic drugs..
