What is glaucoma?

Glaucoma is the name given to the disease that causes an increase in intraocular pressure, which directly affects the structures of the optic nerve, which is responsible for transmitting what we see to our brain. The consequence is a progressive loss of vision which, if left untreated, leads to irreversible blindness.

Glaucoma treatments

Glaucoma, a silent and dangerous eye disease, is one of the leading causes of blindness worldwide. It is characterised by progressive damage to the optic nerve due to increased intraocular pressure, leading to a gradual loss of vision if not diagnosed and treated in time. This condition affects people of all ages, although it occurs more frequently in older individuals.

The optic nerve, which is essential for the transmission of visual information to the brain, is compromised by progressive damage caused by elevated pressure in the eye. The devastating effects of glaucoma can lead to a significant decrease in quality of life, disrupting the daily activities and independence of those affected. In addition, the emotional and psychological impact of coping with vision loss can be overwhelming, highlighting the crucial importance of early detection and timely treatment.

In the search for effective solutions to counteract this disease, various therapeutic approaches have been developed to reduce intraocular pressure and preserve ocular health. These solutions range from medical treatments to more advanced surgical options, each with their own particular advantages and considerations. Let’s take a look at each:

Pharmacological treatment

Firstly, the drug option presents itself as an initial alternative for many patients. The use of eye drops with hypotensive properties aims to lower intraocular pressure and preserve the integrity of the optic nerve. Although this option is easily accessible and applicable, it presents significant challenges, such as the need for regular administration and the possibility of limited efficacy in some cases. In addition, continued dependence on drops may raise concerns about adherence to treatment and potential long-term side effects.

SLT Laser

Another promising therapeutic approach is SLT (Selective Laser Trabeculoplasty) laser treatment, which has been positioned as an effective alternative to reduce intraocular pressure in certain patients. By precisely applying this type of laser to the trabecular meshwork of the eye, a significant reduction in pressure is achieved, which helps to preserve the health of the optic nerve. Unlike eye drops, SLT laser treatment can offer longer-lasting effects and requires less reliance on long-term medication. However, it is also important to keep in mind that this procedure may require more than one treatment as a booster to achieve the necessary efficacy to effectively and permanently lower intraocular pressure.


For those cases where conventional therapeutic measures are insufficient, the surgical option becomes a crucial alternative for the effective management of glaucoma. Glaucoma surgery, often performed by implanting an artificial valve, has gained a prominent place in the treatment of glaucoma. This procedure, which is usually relatively short in duration, offers a more permanent and effective solution to control intraocular pressure. The benefits of this intervention include an early improvement in ocular pressure control, which contributes significantly to the preservation of the optic nerve and visual function. In addition, the possibility of a rapid recovery time and the absence of the need for prolonged hospitalisation make this surgical option an attractive choice for many patients.

Despite significant advances in the diagnosis and treatment of glaucoma, it is critical to stress the importance of early detection and regular follow-up for those at risk of developing the disease. Regular ophthalmological examinations and awareness of risk factors, such as elevated intraocular pressure, advanced age, family history and concomitant systemic diseases, play a crucial role in the prevention and effective management of this eye disease.
