Characterized by damage to the optic nerve, with progressive loss of visual field, glaucoma is a disease that requires great attention as it can lead to blindness. According to the latest data from the World Health Organization (WHO), it is the second leading cause of blindness in the world (12.3%), second only to falls (47.8%). Modern technology now available treatment for glaucoma.
Although the causes of blindness in the world vary according to the economic, social and geographical conditions of each population, glaucoma remains an important cause, regardless of the population evaluated. An estimate indicates that there will be 79.6 million dollars in 2020 glaucomatous.
According to the medical ophthalmologist Leticia Techno, Curitiba, the treatment for glaucoma generally aims to reduce intraocular pressure (IOP) to levels that no longer produce visual field loss. The ideal level of IOP depends on each case and, especially, the degree of evolution of the patient’s glaucoma, says the doctor.
Laser treatment for glaucoma
In most cases medical treatment, which is based on eye drops, may be effective in keeping intraocular pressure lowering. If the IOP cannot be controlled with medication and the patient is at risk to lose sight in treatment for glaucoma, we chose surgical treatment, says the expert. Surgical treatment for glaucoma can be performed with a laser in some situations, such as iridectomy in cases of narrow-angle glaucoma, and in cases of open-angle Trabeculoplasty. Laser treatment may have some effect on IOP reduction, but may not be sufficient.
The main surgery performed to treat glaucoma is trabeculectomy. It is to create fistula drainage of intraocular fluid in the sub-conjunctival space through this treatment, the fluid passes into the eye through a window in the sclera for a bag of Filter scores Leticia Techno.
Success rates in treatment for glaucoma
Success rates are on average, about 80% at the end of a year. In this cases success means that you can keep your eye pressure properly controlled. The results are based on averages in treatment for glaucoma and can vary greatly for each patient. Factors such as age, type of glaucoma, previous surgeries and much influence post-operative care in the outcome.
The reduction of IOP with trabeculectomy is generally the best that can be achieved. And to keep rates low, you can take several interventions after the operation, both early and late. The operation of the filter bag depends on the healing of each person. The visual quality after the operation can be greatly affected, but the overall performance to preoperative levels after one month of surgery, says the doctor.
Other glaucoma surgery techniques may be indicated as deep non-penetrating escelerectomy, drainage implants and cycle-destructive surgery. Recently they have been increasing in the world market denominated minimally invasive techniques (Incision Microsurgery glaucoma) GSI. These are small implants that help the natural filtration of the eye, usually deployed at the same time of cataract surgery. Patient recovery is much quieter and with fewer complications than traditional techniques used in treatment for glaucoma, but they do not yet have the new technology in Europe.
