Expressing that glaucoma is a serious disease that occurs as a result of higher than normal eye pressure and causes blindness, Eye Health and Diseases Specialist Prof. Dr. H. Zeki Büyükyıldız emphasized that the prevalence of the disease, which is also known as ‘black water’ among the people, is 2 percent.


Stating that the risk is 5-6 times higher in those with glaucoma in their family. Dr. H. Zeki Büyükyıldız stated that the incidence rates of the disease also vary according to the types of the disease. Stating that glaucoma is more common in myopia, Prof. Dr. H. Zeki Büyükyıldız pointed out that as the degree of myopia increases, the possibility of glaucoma increases.


Stating that glaucoma is the second cause of blindness in the world, Prof. Dr. H. Zeki Büyükyıldız said that especially those over the age of 40, those with glaucoma in their family, those with diabetes, hypertension, high myopia and vascular disease, and those receiving long-term cortisone treatment are at risk.

Underlining that there are many different types of glaucoma, Prof. Dr. H. Zeki Büyükyıldız stated that the most common type is ‘Primary (Primary) Open Angle Glaucoma’ and shared the following information:

“This type of glaucoma usually does not show symptoms unless the eye pressure is very high. Therefore, it is insidious. However, in closed angle (or angle-closure) glaucoma, the blood pressure rises more than once and the patient comes with a glaucoma crisis. nausea and vomiting may occur. Therefore, the patient may apply to internal diseases or emergency services instead of an ophthalmologist. “


Prof. Dr. H. Zeki Büyükyıldız pointed out that glaucoma may occur after using cortisone eye drops for a long time, in other diseases of the eye, eye tumors, post-operative swollen cataracts, trauma, eye injuries, retinal vein occlusions, advanced diabetes.

Stating that another and serious type of glaucoma is congenital (congenital) glaucoma, Prof. Dr. H. Zeki Büyükyıldız, “Congenital glaucoma, which can occur in one of a thousand births, causes blindness in a short time if its detection is delayed. This type of glaucoma attracts attention with excessive watering, extreme sensitivity to light and squinting of the baby. “Because the tissues are still very flexible, the eye starts to grow with the effect of the tension in the eye, and we may be confronted with a stale fish-eye-like eye due to the enlarged and corneal edema called” Buftalmi “.”


Stating that one type of glaucoma is ‘Juvenile Glaucoma’ seen in young people, Prof. Dr. H. Zeki Büyükyıldız said that although this type is less common, it should be kept in mind that glaucoma may also be present in young people.

Pointing out that it should be known that low blood pressure glaucoma may also occur when eye pressure is below 21 mmHg. Dr. H. Zeki Büyükyıldız gave the following information about this type of glaucoma:

“In these patients, although intraocular pressure is within normal limits, optic nerve pitting, OCT (Optical Coherence Tomography) and visual field tests are detected. Therefore, it is of great benefit to perform glaucoma tests in cases of doubt and hesitation. If low blood pressure (Glaucoma) disease is detected, this type of glaucoma must also be treated. “


Prof. Dr. H. Zeki Büyükyıldız added that when the eye pressure is higher than 21 millimeters of mercury, there are conditions called ‘ocular hypertension’ and no signs of glaucoma.

Stating that eye pressure measurement is of great importance in the detection of glaucoma disease, Prof. Dr. H. Zeki Büyükyıldız said, “Corneal thickness must also be taken into account in the measurement of eye pressure. Blood pressure can be measured low in thin corneas and high in thick corneas. As in our clinic, some measuring instruments give the equivalent of the value measured according to the corneal thickness. “If there is no such possibility, the equivalent of eye pressure measured on a scale with a special chart should be calculated according to corneal thickness.”


He added that ‘Primary Open Angle’ glaucoma is mostly seen after the age of 40 and often does not give any symptoms. Dr. H. Zeki Büyükyıldız continued as follows:

“High eye pressure for a long time disrupts the nourishment of the eye and leads to an increasing dimpling of the optic nerve. Thus, glaucoma starts from the edge vision and gradually causes narrowing in the field of vision. In this period, the patient sees as if he is looking through a pipe. If not treated, finally, the central vision is also. disappears completely and irreversible blindness settles. “


Emphasizing that there is no specific way to prevent glaucoma, but its treatment is possible, Prof. Dr. H. Zeki Büyükyıldız pointed out that when glaucoma is diagnosed as a result of measuring eye pressure at regular intervals, OCT and visual field tests in suspicious cases, treatment should be started urgently.

Stating that the treatment of glaucoma varies according to the type of glaucoma, Prof. Dr. H. Zeki Büyükyıldız made the following statements:

“Drops that reduce eye pressure are used in the treatment of primary (primary) glaucoma. Since the effects of eye pressure lowering drops last for 12-24 hours depending on the type, they do not contribute much to the next day. Therefore, it should be dropped for a lifetime without neglecting even for a day, as recommended by your doctor. If the drops are insufficient to reduce eye pressure or if the nerve fiber damage increases in the examinations, glaucoma surgery is performed. We use YAG laser application, surgery and various medications in angle-closure glaucoma. Treatment planning is made according to the cause in glaucoma caused by secondary reasons. In congenital glaucoma, eye pressure surgery should be performed in the manner recommended by your doctor to the baby. “


Stating that it is beneficial for people who have no complaints, and especially those with glaucoma in their family, to have their eye pressure measured at least once a year. Dr. H. Zeki Büyükyıldız said, “We routinely measure eye pressure for every patient who comes to us in our clinic. Blindness is prevented with treatment, but treatment should not be delayed and the medications given should be used regularly. He ended his warnings by saying that vision loss and eventually irreversible blindness are inevitable in patients who do not mind using drops or who often neglect them.
