Glaucoma in children is most often the primary or innate. But it can be a consequence of some other eye diseases or general, that is secondary. All kinds of children's glaucoma often subject to surgical treatment, which should be carried out in a timely manner - the only way to save the child vision.
Primary glaucoma in children
Primary glaucoma in children is congenital in nature. However, it can be either inherited or developed as a result of the adverse effects on the organs of vision in utero. It can be various viral infections (especially dangerous rubella), intoxications (smoking, alcohol abuse, a reception of various drugs in the first 12 weeks of pregnancy, the effects of radiation and so on).
As a result of all these reasons, the child is formed malformation of the eye, causing a violation of the outflow of intraocular fluid. The liquid gradually accumulates in the anterior chamber of the eye, causing an increase in intraocular pressure (IOP), and this in turn leads to a stretching of eyes, increase the size of the eyeball, and the expansion of the optic fissure, corneal edema.
Under the influence of high IOP varies the iris (some of its tissue may die out even partially) that leads to expansion and sometimes change in shape of the pupils which thus react to light sluggish. Significant changes may occur in the lens - increased IOP leads to stretching of the ligaments that hold it, they tear, subluxation or dislocation of the lens, in violation of its metabolic processes and the formation of cataracts.
Constant pressure on the optic nerve head leading to its rapid atrophy and formation of blindness.
The first manifestations of children's primary glaucoma are photophobia, lacrimation, slezostoyanie eyes.
The sooner the first signs of glaucoma

, The harder runs its course. In older children stretching cornea and sclera in glaucoma leads to significant violations of refraction - formation of nearsightedness or farsightedness. Since glaucoma

usually manifests itself in varying degrees in the right and left eye, such changes may cause strabismus.
Secondary glaucoma in children
Pediatric glaucoma can be secondary. It can develop, for example, after cataract surgery
Cataract surgery - surgery
(afakicheskaya glaucoma), and glaucoma may not appear immediately, but after a few years after the operation. To explain the mechanism of glaucoma in this case is not always possible. But in most cases, after the surgery takes place the proliferation of adhesions in the anterior chamber angle. Afaktichekaya glaucoma is difficult to treat and often leads to blindness.
Secondary glaucoma can develop children also in severe retinopathy of prematurity, with significant damage to the retina. The mechanism of this glaucoma is associated with exposure to the eye tissue of many factors, which leads to a violation of the outflow of intraocular fluid and increase in IOP with all its consequences.
Sometimes the child has a congenital abnormality of the lens. Typically, a small spherical lens, which often moves anteriorly. That violates the outflow of intraocular fluid and causes the formation of glaucoma.
In adolescence, secondary glaucoma
Secondary glaucoma - against the backdrop of another disease
It may be due to juvenile ksantogranulemy - intraocular benign tumor. Glaucoma is thus a consequence of compression of blood vessels and bleeding. Just as in adults, children glaucoma can develop for inflammatory diseases of the eye, eyeball injuries, degenerative processes.
Diagnosis and treatment of child glaucoma
Manifestations of secondary glaucoma in children is the same as that of the adults, but impairment in children formed will therefore detect glaucoma at an early stage in this age is especially important.
In the diagnosis of children's glaucoma doctors faced with certain difficulties, as many research methods can not be used in children in primary care. In this case the baby is hospitalized, and all the necessary diagnostic procedures are performed under anesthesia.
Children's Glaucoma Treatment in most cases surgery - to delay the payment of IOP using conservative treatment often inappropriate and even dangerous.
However, the drug treatment of glaucoma in children successfully used in preparation for the operation to align the IOP in a rehabilitation treatment after surgery.
Surgical treatment of glaucoma and children's choice of the type of surgery depends on the identified congenital or acquired disorders of intraocular fluid.
