Cataract Surgery Glaucoma Patients
We need to know together that glaucoma and cataracts are two types of eye diseases that can both cause blindness. According to the World Health Organization (WHO), glaucoma is the second largest cause of blindness worldwide after cataracts. Glaucoma is a type of visual impairment with damage to the optic nerve caused by pressure in the eye. Glaucoma is a visual disease due to high pressure on the nerve fluid that damages the eyes. Glaucoma is characterized when the optic nerve is damaged due to pressure on the eye. The cause of glaucoma is an increase in pressure in the eye (intraocular pressure), both due to excessive production of eye fluid, as well as due to obstruction of the drainage of the fluid. This pressure can damage the retinal nerve fibers and the optic nerve that connects the eye to the brain as well. Until now, it was not clear why the production of eye fluids could be excessive or why the drainage can be blocked.
There are two types of glaucoma, the most common of which is closed-angle glaucoma and open-angle glaucoma. In cases of closed-angle glaucoma, the pressure that occurs in the eye is caused by poor drainage due to the blocked canal blocked by the narrow angle between the cornea and the iris. In this case, symptoms often develop quickly or acutely. People affected by this condition will experience pain and red symptoms in the eyes, vision becomes blurred, headaches, nausea and vomiting, such as seeing halos around the lamp. Symptoms of acute closed angle glaucoma can appear – disappear for an hour or two. Cases of closed angle glaucoma are more common in Asian countries. Whereas in the case of open-angle glaucoma, the structure of the eye appears normal, but there is a problem in the eye canal called the trabecular meshwork. This problem causes eye fluids to not flow properly. This is different from closed-angle glaucoma, symptoms in cases of open-angle glaucoma often develop slowly or chronic. Patients with this condition are barely aware of the damage that occurs to their eyes. The main characteristics of chronic open-angle glaucoma are the gradual decrease in peripheral vision in both eyes, before finally becoming very narrow or tunnel vision.
In addition to the two types of glaucoma above, there are other types of glaucoma, secondary glaucoma and congenital glaucoma. Secondary glaucoma is caused by inflammation in the middle layer of the eye (uveitis) or injury to the eye. While congenital glaucoma is caused by abnormalities in the eye (congenital conditions). Congenital glaucoma is experienced by children. In cases of secondary glaucoma, symptoms of glaucoma will be accompanied by symptoms of the underlying condition. An example is glaucoma caused by uveitis. Aside from blurred vision or like seeing halos around the lamp, the patient will also feel pain in the eyes and head, which is also a symptom of uveitis.
Thus glaucoma must be diagnosed and treated as early as possible. If this condition is ignored, then this disease will continue to develop and the sufferer can experience permanent blindness. Eye damage caused by glaucoma cannot be completely treated (vision cannot be completely normal again). However, the goal of treatment of this condition is to reduce intraocular pressure on the eye and prevent widespread damage to the eye. Before performing cataract surgery, you need to know how bad your glaucoma is, and you need to evaluate the optic nerve and visual field. Performing cataract surgery in glaucoma patients must be performed the simplest and cleanest surgery. Perform surgery in glaucoma patients not only to reduce pressure, but based on visual needs. Performing surgery in glaucoma patients must be prepared in case of IOP elevation (without vision-based indications). The main thing to remember is that cataract patients who also have glaucoma should not be treated like simple cataract patients. If you evaluate the patient’s disease carefully, perform careful surgery and follow up diligently, glaucoma patients will end up with good and happy eyesight. It is very important to immediately see a doctor if you experience a decreased power of view which may be caused by glaucoma. Eye damage caused by glaucoma cannot be treated or repaired again. However, the goal of treatment of this condition is to reduce intraocular pressure on the eye and prevent widespread damage to the eye. In general, glaucoma can be treated with eye-drops, medications taken, laser therapy, and surgery.
