Prevention of Postoperative Vision Loss: A Case Study

Prevention of loss of visual acuity after surgery: Postoperative loss of vision (POVL) other than during case surgery is a rare but devastating problem related to many types of surgery and patient risk factors (Stoelting & Miller, 2007). Stoelting and Miller reported that the incidence of POVL in patients who received non-surgical operations other than the heart increased from 60,965 points to 125,234 points, from 0.06% to 0.113% in patients who underwent cardiopulmonary bypass surgery, and 0.09% of peritoneal saphenous surgery It was estimated that it increased.

There is no known method for preventing glaucoma, but if the disease is recognized early, it can prevent blindness or marked visual loss of glaucoma. In its most common form - primary open angle glaucoma - the loss of vision is silent, slow and progressive. Normally, it affects side view (peripheral vision) first, and central vision loss occurs as visual acuity progresses

Neurological visual disorders usually include loss of central vision, loss of vision on one side of the field of view, or loss of the entire field of view. In some cases survivors may be able to see the front and sides, but their field of vision remains blurred. Other people may see it clearly in the daytime, but they will encounter great difficulties indoors or at night. Unlike neurological loss, the human eye is associated with obvious symptoms, so it is more likely to detect other eye diseases. Since many of these symptoms are well known, diagnosis and treatment are often simple. Remember to pay attention to both types of loss of vision to bestify your symptoms to your doctor if there is a change in your vision. Several common eye diseases unrelated to nervous system events are as follows.

Taurine is particularly important from the viewpoint of eye health. Proper levels help prevent premature vision loss; conversely, defects can cause vision problems. Age-related loss of vision has various causes, but closest is the effect of oxidative stress on the photoreceptor of the retina. This injury causes age-related macular degeneration and other forms of retinal disease 45. Although the taurine concentration in the retina is very high, taurine decreases markedly as the age rises 46-48. Taurine is known to be resistant to oxidative stress, especially in diabetic patients, and helps to restore the nerve growth factor levels necessary to maintain retinal health 46, 30, 31

Diabetic retinopathy is the leading cause of blindness and vision impairment. Diabetes is associated with small blood vessel damage in the retina and leads to blindness. Consistently from research to research, after 15 years of diabetes, it can be shown that about 2% of people are blinded and about 10% have severe visual impairment. The loss of visual acuity caused by certain types of glaucoma and cataracts is also more common in people with diabetes than those who do not.
