Secondary glaucoma is a consequence of other eye diseases, so it can begin at any age. The most common secondary glaucoma develops against the background of inflammation and vascular disorders of vision. Treatment of secondary glaucoma - is primarily the treatment of underlying disease.

The causes of secondary glaucoma

The cause of secondary glaucoma are often infectious and inflammatory eye tissue bacterial or viral nature. For example, an acute inflammation of the choroid (acute uevit) is accompanied by accumulation of intraocular fluid in the anterior chamber and the deterioration of its outflow. Chronic uveitis is accompanied by the formation of adhesions and adhesions in the anterior chamber of the eye. This disrupts the normal flow of intraocular fluid and contributes to intraocular pressure.

Secondary glaucoma may also develop in the blood circulation in the vessels of the eye, orbit (often associated with thrombosis of blood vessels) and intraocular hemorrhage. The causes of secondary glaucoma may also be shifts of the lens, cataract Cataracts - how to solve the problem completely?   (at the time of swelling), exchange-degenerative eye diseases (such as atrophy of the iris), tumors, trauma, burns, eye surgery in this area (eg, cataract surgery).

Signs of secondary glaucoma

Signs of secondary glaucoma are closely connected with the signs of the underlying disease. Develop secondary glaucoma as well as the primary. Distinctive features of the secondary process are:

• unilateral development processes;
• increased intraocular pressure in the evening;
• development process, such as the type of open-and-closure glaucoma;
• the rapid decline of (sometimes for years); but with time initiated adequate treatment is often sight restored.

The first signs of secondary hemorrhagic glaucoma, developed against thrombosis of the central retinal vein appear about six months after the onset of the disease. Intraocular pressure may be increased at the same time significantly to the development of acute attacks of glaucoma. Sometimes glaucoma Glaucoma - a perspective possible blindness   may develop after a while after cataract surgery by type of openness or closure.

Traumatic glaucoma develops at a young age after eye injuries and divided by the wound, surgical, burn, chemical, ionized. Depending on the mechanism of tissue damage eyes glaucoma may be either open-and-closure. Traumatic glaucoma develops after a certain time after the injury, sometimes a few months, sometimes - in a few years and usually runs hard.

Glaucoma against the backdrop of an intraocular tumor occurs when the blockade growing tumor of the anterior chamber angle and deposition of decomposition products of tumors in the drainage system of the eye. Therefore, this glaucoma may be open-and-closure. When tumors orbit glaucoma due to the increase of pressure in the veins of the eye socket, or direct pressure on the eyeball tumor.

Diagnosis and treatment

Secondary glaucoma is detected by careful examination of the patient, identification of elevated intraocular pressure and visual impairment on the background of inflammatory, vascular disorders, trauma, tumors, and so on.

However, drugs that reduce intraocular pressure, may impair circulation to the area of ​​the eye that will lead to disease progression. Especially if it is based on vascular processes.

That is why it is sometimes necessary in the surgical treatment which developed open-or closed-angle glaucoma. This need arises in the failure of conservative treatment, persistent elevations of intracranial pressure and reduced visual function.

Secondary glaucoma requires, first of all, a comprehensive examination of the patient. Only after the final diagnosis to the patient may be adequate therapy or (if necessary) surgery.

Complications of cataract is called a disorder in which the clouding of the eye lens is a result of certain diseases, or to harmful external influences. Complicated cataract occurs in different age groups and the severity of disease often depends on the age of the patient.

When disturbed nutrition complicated cataract eye lens, and / or his exposure to harmful toxins. Anyway, as a result of the lens to appear dull spots due to which the human eye is significantly reduced. Complicated cataract may have a negative impact on all important aspects of human life - from professional activity to the possibility of unassisted play sports, travel, and even just to serve themselves at the household level.

Epidemiology

It is estimated that in 48% of cases the cause of vision loss in the elderly are certain types of cataracts, and complications including cataract.

In the low quality of medical care cataract Cataracts - how to solve the problem completely?   is the leading cause of blindness in the elderly.

In recent years, diabetes in some countries has become increasingly common disorder, and gradually "younger", and because it is one of the most common causes of complicated cataract, there is reason to fear that the disease will become increasingly common.

Complicated cataract is increasingly observed in areas where people are exposed to the most intense ultraviolet radiation. It is expected that the situation will get worse if you keep the depletion of the ozone layer.

Causes and risk factors

The causes of cataracts can be complicated:

• Retinal detachment, which for a long time remains untreated;
• Chronic iridocyclitis;
• Chorioretinitis;
• Glaucoma;
• Intraocular tumors;
• Taking certain types of medications, such as corticosteroids, eye drop pilocarpine and epinephrine;
• Intense and prolonged exposure to ultraviolet radiation;
• Exposure to ionizing radiation;
• Diabetes;
• Hypertension;
• Damage to the eye;
• Genetic predisposition;
• Iodine deficiency.

The following factors increase the likelihood of complicated cataract:

• Age. Like most types of cataract, complicated cataract develops most often in older people;
• Paul. Women are more susceptible to this disease than men;
• Complicated cataract family history.

Symptoms

The most common symptoms of complicated cataract are:

• Blurred vision;
• Ghosting visible objects;
• The emergence of vision problems - first to the patient can be difficult to read the text typed letters, which he had seen well, then deteriorating night vision, and so on;
• "Milk" color pupil.

Diagnosis of complicated cataract

People who have eyesight began to deteriorate, or there were other possible signs of complicated cataract, you should consult an ophthalmologist or your family doctor so that he gave a referral to a specialist.

The ophthalmologist examines the patient (during the inspection, you can sometimes see small muddy areas on the eyes), and normal vision test. To detect possible damage in the structure of the eye, the survey is conducted by using an ophthalmoscope. It is important that the patient is a detailed description of their symptoms, as well as spoke about the transferred recently illnesses, operations, injuries, and medicines that he takes - this information is necessary so that the doctor can make the most complete picture of the patient, and make the first assumption about the reasons for the emergence of vision problems.

In the process of differential diagnosis of the doctor is necessary to rule out diseases of the cornea, eye tumors, glaucoma Glaucoma - a perspective possible blindness , Head trauma, retinal detachment Retinal detachment - when the leaves sight , Pupillary defects, trauma to the eye.

Treatment of complicated cataract

With relatively mild forms of complicated cataract doctor may recommend the patient to wear glasses or contact lenses Contact lenses - whether they can completely replace the glasses? Work or read at a bright light and undergo regular inspection. In cases when the disease has resulted in a significant deterioration of vision which can reduce the quality of life, require surgery. Which type of surgery will be assigned it depends on the causes of complicated cataract. In any case, the cataract is removed, and then will be produced an intraocular lens implantation - or an artificial lens. Rather, vision after such operation will not be perfect, and the patient would still have to wear glasses, but surgery will prevent further vision loss and, in some cases, its total loss.
