Q: When my eyes are dimly lit or when the natural light is not bright enough, I get blurred vision, which gets worse as time goes on, and I even get swelling and pain in the corner of my right eye, but my vision is gradually restored when I am in bright light or when the natural light is bright. When I use my eyes for a long time, I also have blurred vision, and now I have to use high magnification when reading. I went to the ophthalmologist and was diagnosed with senile cataract and retinal arteriosclerosis degree II. How can I treat this condition? What should I pay attention to in normal times? A: Age-related cataract is a disease of aging. As we age, the lens gradually hardens and becomes cloudy, resulting in visual impairment. The treatment of cataract is divided into two methods: non-surgical and surgical. In the initial stage of cataract, eye drops such as cataract stop and catharine can be taken to slow down the progress, but medication for cataract cannot completely eradicate the clouding and development of the lens so far. Therefore, surgical treatment is still the main means of treating senile cataract. From the patient’s chief complaint and the optometrist’s opinion, the patient’s cataract has developed to the extent that it affects his daily life and work. If the visual acuity of the affected eye is below 0.4, surgical treatment is feasible. The better surgical method at present is small incision cataract ultrasound emulsification + folding IOL implantation. As long as the general condition is good and there is no obvious fundus lesion, the effect of surgical treatment is still relatively ideal. Retinal atherosclerosis is a manifestation of systemic atherosclerosis or senile lesions in the eye, commonly associated with hypertension, diabetes and kidney disease. Retinal arteriosclerosis is usually classified into 4 grades, the higher the grade, the more severe the sclerosis. Grade 2 retinal arteriosclerosis is more severe than grade 1, with more obvious narrowing of small arteries and widening of reflective bands, uneven narrowing of arterial diameters, and arteriovenous cross-indentation. Treatment is based on the treatment of primary systemic diseases, i.e., control of blood pressure and blood sugar, and treatment of kidney diseases. Ophthalmology can take Chinese herbs such as Salvia and Ginkgo biloba to improve microcirculation, or take pancreatic kinase releasing enzyme tablets, etc., which can improve cardiovascular circulation, reduce blood viscosity and treat retinal arteriosclerosis in the fundus.
