Glaucoma Treatment in Dubai
Glaucoma is one of the main causes of blindness, but this can be avoided if it is diagnosed and treated in time. Glaucoma is a disease of the optic nerve, which is the set of nerve fibres that transmit visual information from the eye to the brain. Modern diagnostic techniques, new medications and innovative surgical procedures are improving the fight against this devastating disease, known as silent blindness.
With glaucoma, the optic nerve is progressively damaged, irreversibly losing nervous fibres. Patients gradually lose their vision, first in the peripheral visual field, and then in the centre. Unfortunately, a person suffering from glaucoma only notices this loss when the disease is advanced, and goes to the ophthalmologist when it’s already too late. High ocular pressure is asymptomatic in most of the cases.
What causes Glaucoma?
Glaucoma is a multifactorial disease. Most glaucomas are caused by an increase in pressure within the eye. Ocular pressure is measured in millimetres of mercury. When the value is 22 or above, we consider there to be ocular hypertension.
Detecting ocular hypertension requires undergoing an examination to see if glaucoma has been produced or not. If no glaucoma is detected, the ophthalmologist will decide whether to start preventive treatment or supervise the patient with no treatment.
In some cases, glaucoma can occur without ocular hypertension; the main causes are insufficient vascular irrigation, or a particular weakness of the optic nerve.
The risk of suffering from glaucoma increases with age. Thus, it is important to attend periodic eye examinations, every two years, for people between 40 and 60 years of age, and every year after 60.
The risk for direct family members of a person who has been diagnosed with glaucoma is higher than the general population, and they must have periodic examinations.
Types of Glaucoma
The most common glaucoma is called open-angle primary glaucoma. In this type of the disease, ocular pressure is usually slightly or moderately high. In other cases, called open-angle secondary glaucoma, there is a specific cause that raises ocular pressure.
Finally, and the least common in our environment, is angle-closure glaucoma, which may be acute (causing pain and quick loss of vision) or chronic. Diagnosing the type of glaucoma is very important, since their treatment may differ.
Tests to diagnose and monitor Glaucoma
Glaucoma is a chronic disease, and requires specific tests, both for its diagnosis and for its long-term control.
The main tests performed are:
- Examination and photographing of the optic nerve
- Determination of ocular pressure (tonometry)
- Examination of the irido-corneal angle (gonioscopy)
- Determination of the corneal thickness (pachymetry)
- Examination of the visual field (campimetry)
- Measurement of the nerve fibre layer and the optical nerve (GDx, OCT)
Loss of the visual field, with glaucoma, is progressive.
Our specialists have the latest and most advanced technology for diagnosing and controlling glaucoma, which allows them to detect the disease in time, and monitor its evolution in the most precise way possible.
Glaucoma treatment always includes a reduction of the ocular pressure. For this, different alternatives may be used, such as eye drops, laser or surgery. The choice of one treatment or the other depends on both the patient’s and the disease’s characteristics.
Our glaucoma specialists in Dubai will study and evaluate each situation, and inform the patient of the therapeutic decisions that should be made. But the sooner the glaucoma is diagnosed, the better the results, so, early checks in case of any risk factor is key.
