Glaucoma Surgery


Glaucoma is a condition in which eye pressure rises due to the fluid in the eye not draining enough. Normally, intraocular fluid is constantly produced and this is regularly thrown out of the eye with the help of channels in the eye. Glaucoma is one of the most common causes of permanent vision loss affecting millions of people worldwide. It can be seen in approximately 1 in every 40 people over the age of forty, and in 1 out of 20 people with the disease, it can cause permanent vision loss, i.e. blindness in both eyes.
High intraocular pressure damages the eye nerve and, if left untreated, causes vision loss leading to blindness.
What are the glaucoma symptoms?
Unfortunately, there are no signs and symptoms in the early stages of eye pressure. Some patients may have mild headaches or pain around the eyes. Patients sometimes complain of temporary visual blurring and report seeing rings around the lights. Feeling stiff in the eye, The pain of pressure is a complaint of some patients.
However, in subtype glaucoma called “angle-closure glaucoma”, severe pain and redness may occur in the eye. Also, these patients may be experiencing severe headaches, nausea and vomiting, and a sudden decrease in vision. Patients with this symptom should immediately contact an ophthalmologist.
In another subgroup, congenital glaucoma has an effect of excessively large eyes and can be spotted by careful parents.
Risk Groups
Although glaucoma can be seen at anyone and any age, especially the following people have more risks. Patients with;
  • a family member who has glaucoma
  • diabetes, hypertension
  • Those over the age of 40
  • high myopia
  • vascular disease
  • Long-term cortisone treatment
  • Eye injuries.
It is needed to have eye examinations for the risk of having glaucoma for the patients these points apply to.
Diagnosis of glaucoma
Early diagnosis is very important in glaucoma since the disease, which is common in what we call open-angle glaucoma; progresses insidiously and does not show any symptoms, damage to the optic nerve and vision loss cannot be reversed. The earlier the disease is detected, the less vision loss will be experienced. A detailed eye examination performed by a specialist ophthalmologist for the diagnosis of glaucoma is very important. Many special tests need to be done for the diagnosis of the disease.
One of these is visual field evaluation. While there is not much effect in the early period of the disease, as the disease progresses, black spots and narrowing occur in the visual field, and when the disease progresses further, patients see it as if they look through a pipe.
Treatment of glaucoma
After the diagnosis of glaucoma disease, the purpose of treatment for today is to stop eye nerve damage by reducing eye pressure and prevent the progression of vision loss. The methods that can be applied for this purpose can be gathered under three main titles.
  • Medication
  • Laser therapy
  • Surgical treatment
Even though the first method chosen after the diagnosis is medicine treatment today, laser treatment or surgical treatment methods are applied in patients who do not respond adequately to medicine treatment, direct laser interventions or surgical methods are also used especially in cases where a late diagnosis of continuous medicine use is not appropriate. Significant improvements have been made in medicine treatment in glaucoma in recent years, and effective new medicines have greatly increased the success of the treatment. The important thing in medicine treatment is that the patient uses medicine regularly. Surgical methods used in patients who can not use medication or do not respond to medicine treatment have been increasingly successful in recent years, and they can provide effective treatment by removing the necessity of continuous medicine use.

What Is Cataract?

Cataract is the opacity of the lens by losing its transparency. The eye has an optical structure and the images coming from the external environment are first refracted through the cornea, which is the transparent layer on the outermost part of the eye, and then through the lens layer inside the eye, and thus it is clearly transmitted to the visual center. It causes the images to be blurred and not transmitted to the center of vision clearly by adding the lens formed in the lens. Sometimes cataracts become so intense that people cannot see anything except to feel the light. People who develop cataracts see it as if they are looking through a misty or frosted glass. Although there are many types of cataracts, the most common cataracts are cataracts that develop with age.   What are the Cataract types? Nuclear cataracts: A nuclear cataract may at first cause a temporary improvement in your vision. But with time, the lens gradually turns more densely yellow and further cloud...

Periodontology (Gum Disease)

In cases where oral care is inadequate, a bacterial plaque that is a rich, soft, sticky layer of microorganisms on the tooth surface accumulates. This layer causes gingivitis with tooth decay. Healthy gums are pale pink in color, with orange peel appearance and hardness. When the gums lose their health they are swollen, red, bleeding and moving. If the treatment is delayed, the tooth stones accumulate causing the bone surrounding the tooth to erase. The gums start to pull out. This condition is both sensitive to heat changes and causes aesthetic problems as well as oral odor and even dental inflammation in very advanced conditions. If they go further, tooth loss starts. Gum disease also occurs in the case of inadequate oral care, hormonal changes, genetic factors, drug use, some systemic diseases; If there is a problem already existing, it progresses rapidly. There is a gap between the tooth and the gum called pocket which we can not see with eyes. It should be treated when it re...
