Closed glaucoma: symptoms of the disease
Closed-angle glaucoma is a pathology that correlates with the overlap of the angle of the anterior chamber of the eye. The disease can develop rapidly or chronically. Symptoms of acute form is the appearance of severe pain and redness in the eye, impaired vision, the presence of headaches, nausea with vomiting. Intraocular pressure remains elevated. The acute condition of the patient requires urgent treatment with the help of systemic and local drugs in order to prevent complete loss of vision.
Closed glaucoma is usually caused by factors that cause the movement of the iris root into the angle of the anterior chamber. This is how the block is formed for normal drainage of moisture and the pressure inside the eye increases.
The closed-angle form of glaucoma can be primary or secondary type, as well as acute, chronic or subacute type.
The causes of the pathology of
The main risk factors for the development of closed glaucoma are:
- functional reasons for overlapping the angle of the front chamber;
- age features of the visual organs.
The anatomical features that can lead to the development of closed glaucoma include: a small eye size, a small front camera, a large lens size, a too narrow anterior camera angle and farsightedness. For functional reasons should be attributed: increased fluid production inside the eye, increased blood filling of the vessels inside the eye, dilated pupil.
Taking certain medications increases the risk of defeat by closed glaucoma, especially with tranquilizers, which are used to relieve depressive conditions and normalize other psychiatric disorders.
Symptoms and manifestations of
When developing an acute form of closed glaucoma, the following symptoms appear: red eye, pain, blurred vision, iridescent eyes, headaches and nausea with vomiting. Sometimes the common symptoms become so severe that the patient is diagnosed with an incorrect diagnosis of gastrointestinal upset and neurological pathology. During the examination of the patient, he is diagnosed with conjunctival injection, corneal turbidity, pupil immobility and effusion in the anterior chamber. At the same time, vision is reduced. In connection with edema of the cornea, it becomes difficult to examine the optic nerve.
The chronic form of closed glaucoma is often similar to the symptoms of open glaucoma. Patients complain of the redness of the eye, a sense of discomfort, a nebula of vision and headaches that are weakened in a dream. Intraocular pressure has normal values, but on the affected eye they are somewhat higher than on the healthy one.
The process of treatment of
disease For the rapid reduction of intraocular pressure indicators in the development of an acute attack of closed-angle glaucoma, several medications are used. The ingestion of a mixture of water and glycerin reduces the level of pressure and stops the attack.
Eye drops, which include pilocarpine, help spread the iris, narrow the pupil, thereby opening the channels for fluid outflow.
After an attack, do not stop treatment. The doctor appoints the patient several doses of carbonic anhydrase inhibitors and the use of eye drops. In severe cases, mannitol is injected intravenously to reduce pressure inside the eye.
Often, laser surgery is used to treat occlusive glaucoma, which provides fluid drainage by creating a hole in the iris. Such manipulations can prevent the development of seizures in the future and help to achieve full recovery.
In a situation where laser surgery does not cope with the problem, an operation is organized. If the presence of narrow channels for outflow of intraocular fluid is characteristic for both eyes, then the treatment process involves affecting both, even when only one eye is affected.
