Glaucoma

It is a disease that affects the optic nerve. The main risk factor that you have and that we can control is the increase in intraocular pressure (IOP).

Early detection is critical.

Definition and type

Glaucoma is a set of diseases that have as a common feature an atrophy of the optic nerve with a loss of visual field. Increased intraocular pressure is the main risk factor.

Aqueous humor is a liquid that occurs inside the eye, in a structure called ciliary processes, and is removed by the trabecular meshwork. This mesh is located in an area that forms an angle between the iris and the cornea.

Glaucoma can be open or closed angle, and can also be primary or secondary to other ophthalmic pathologies. Primary open-angle glaucoma is the most common type of glaucoma, with the World Health Organization estimating an incidence of more than 2 million new cases each year.

Having a family member with glaucoma increases your risk of developing it. Several genes related to glaucoma have been identified, such as the TIGR gene, GLC1A, GLC1B, GLC1C, etc.

Glaucoma usually appears in adulthood (from the age of 40), although there are cases of congenital, childhood and juvenile glaucoma.

Diagnosis

Glaucoma manifests itself clinically as a slow, progressive, and irreversible loss of visual field that is not perceived by the patient until it reaches advanced stages, in which peripheral vision is already greatly reduced.

A basic ophthalmological check-up makes it possible to diagnose this pathology in most cases. Apart from the ophthalmological examination, there are different complementary tests that help us to diagnose and monitor this disease. Some of them are:

Normal OCT
Glaucoma OCT

Treatment

Glaucoma treatment is aimed at lowering intraocular pressure, improving eye flow, and reducing oxidative stress. To do this, we have several tools:

Conclusions

Patients with glaucoma do not perceive the loss of visual field until very advanced stages.

Given that glaucoma is a highly prevalent and irreversible disease, an early diagnosis is vital.

With an early diagnosis and appropriate treatment we can avoid a significant loss of vision that, in the worst case, can lead to blindness.

Regular check-ups are recommended for everyone over the age of 40, and earlier if there is a family history of glaucoma.
