Types of Glaucoma
Angle Closure Glaucoma
It can be hereditary and can be seen simultaneously in different individuals of the same family. It is more common in asians and hypermetropia. In these people, the anterior chamber is shallower than the normal ones. The angle between the cornea and the iris is narrow. As you get older, this angle becomes narrower and IOP increases as the lens grows. Acute glaucoma occurs when the angle is completely closed. IOP suddenly rises in acute glaucoma. The patient feels a lot of pain, even nausea and vomiting. The eye is red and the cornea becomes blurred. The patient sees halos around the light and the vision decreases. This is an emergency. If treatment is delayed, vision is lost. The trabecular network may become chronic and the disease may become chronic and the treatment of this condition is even more difficult.
Open Angle Glaucoma
The most common type of glaucoma. It is seen in about 1% of society and more than 40 years of age. It does not give any indication in the early period. Since the intraocular pressure rises slowly, the symptoms start slowly, the cornea does not start at the beginning, pain is not felt. As the vision is lost slowly, the patient may not be aware of it until late. When the loss of vision became apparent, the damage became permanent. In open angle glaucoma, the trabecular network, which is the drainage region of the eye, creates a resistance that we cannot fully solve. This is a chronic disease. There is a possibility of heredity. Today, there is no definitive treatment, but the progression of the disease can be slowed or stopped by the means at hand. Medications may need to be used for a lifetime.
Glaucoma in children
Infant eye pressure is seen. We can separate this disease into two: a baby with congenital eye pressure, which has big eyes on the first day of birth, and the colored parts of his eyes are the husband. Due to the water collecting of the transparent layer; eyes appear gray. They are disturbed by light, they have severe life. There are also those who have caught this disease in time after birth. When babies are in the mother’s womb, (in the case of water being produced in the eye), the filter system of the eye leaving the liquid is closed with a membrane. It occurs on the membrane of the right to birth. The fluid from the perforations begins to come out. While the baby completes the development of the mother’s womb, the fluid-escaping filter system of the eye may not develop sufficiently, and eye pressure is formed. The most common is the birth. Among these, the most dangerous group eye color is not grayish, the eye pressure is not very high, and only the eyes are large babies. Because these babies are diagnosed late. In order to do this, parents must bring their children to an ophthalmologist with large eyes, who cannot care for light and have severe lifestyles. The treatment of eye tension in infants is surgery because it does not develop fluid outflow channels. Infant’s blood pressure is difficult to treat. The sooner he’s identified for her, the better.
In older people, a material such as hair dandruff accumulates on the lens. With the movement of the iris, this material dislocates and clogs the drainage channels with the pigment.
From birth. Within a few months, the eye is characterized by a marked growth, watering and blur. If early surgical treatment is not performed, it ends with blindness.
It is a very severe form of glaucoma. In the nerve layer of the eye, when there is a condition that prevents diabetes, vascular occlusion or any other way of feeding, abnormal vessels develop and they cover the angle.
Glaucoma after injury:
Obstruction of the eye, chemical burns or penetrating injuries can lead to acute or chronic glaucoma. The reason is generally related to the failure of the drainage system. Therefore, people with eye injuries should be checked at regular intervals.
Normal Pressure Glaucoma
Also known as low pressure glaucoma. There is visual field loss and visual nerve damage in spite of normal IOP. These individuals need to be drawn to lower IOP because of a circulatory disorder in the visual nerve. And this is the exact opposite. Although IOP is high, there is no loss of visual field and visual nerve damage. This is called eye hypertension and does not require treatment. However, as it may turn into glaucoma in the future, follow-up is necessary.
In some eyes, intraocular pressure can be detected above the mean values, but no visual field damage is detected. In other words, the vision nerves are normal. In these cases, treatment is not necessary unless the intraocular pressure is not adequately elevated, but should be strictly followed.
It is a form of open angle glaucoma. It is more common in men. Usually starts at the age of 20-30. It is more common in myopia. In these individuals, the iris is close to the lens and gives the eye color
