Attention to Permanent Vision Loss

Kiss. Dr. Mustafa Duran said, “Diabetes patients may experience permanent vision loss and eye damage if their eye health checks are delayed.”

Diabetes, also known as diabetes among the people, can affect the whole body and cause great damage to the eyes. Medicana Samsun Hospital Ophthalmology Specialist Op. Dr. Mustafa Duran gave detailed information about the treatment process and precautions.


Kiss. Dr. Mustafa Duran stated that diabetes is a disease that occurs as a result of the deterioration of blood sugar (glucose) metabolism in the body, and said, “As a result of high glucose levels, disorders begin in the body’s vessels. This causes eye, kidney and cardiovascular system diseases. Diabetes is one of the most important causes of vision loss between the ages of 20-65. Diabetes causes eye diseases such as cataracts, glaucoma, and diabetic retinopathy with bleeding and edema behind the eye. The risk of eye damage increases in proportion to the duration of diabetes and the high level of glucose in the blood. Control of blood sugar is also very important in the treatment of eye damage (retinopathy) in diabetes.


Ophthalmology Specialist Op. Dr. Mustafa Duran said, “Micro aneurysms (ballooning in the vessels) and small hemorrhages are seen due to deterioration in retinal vessels in the early stages. Since the vision is not affected in cases where the visual center is not involved, the patient does not have any complaints, but this early period can be caught with routine eye examinations and preventive measures can be taken against progression. If these leaks in the retinal vessels hold the visual center, complaints of decreased vision begin. During this period, macular OCT and eye angiography (FFA) films are taken and the results are evaluated. According to these, intraocular (intravitreal) anti-VEGF needles or argon laser treatment is decided. In some cases, both treatments are applied together. If treatment is delayed, retinal vascular occlusions, large intraocular hemorrhages (vitreous hemorrhage) and fibrotic bands in the retina occur. During this period, patients’ vision decreases even more. At these stages, in addition to needle and laser treatments, operations called vitrectomy applied to the back of the eye are performed. Permanent vision loss and eye damage may occur in patients who are delayed.


Diabetes patients should have an eye examination after diagnosis and go to 6-month or annual check-ups in line with the recommendations of the ophthalmologist in order to prevent eye diseases related to diabetes and to prevent the patient from experiencing vision loss.
