How can diabetic patients prevent eye diseases?

Abstract: diabetic patients are prone to have ocular fundus lesions due to their body functions. Diabetic cataracts and diabetic retinopathy are common. With the continuous improvement of living standards,

has been increasing the nutritional content of food and the incidence rate of diabetes has been increasing. Diabetes is an endocrine metabolic disease, which can cause microcirculatory disturbance. With the prolongation of the course of diabetes, a series of complications can occur in the eyes. The most common is diabetic cataract, the other is diabetic retinopathy. Generally speaking,

and

do not have obvious complications in the eyes with short duration of diabetes and good blood sugar control. However, diabetic patients with a duration of more than 10 years have varying degrees of eye changes even though their blood sugar is well controlled. Some patients come to ophthalmologic examination due to poor visual function and suspect diabetes. The

diabetic cataract

and

had a younger age, mostly binocular, mature faster, and lens opacification. The characteristic was first from the posterior capsule of the lens, and then appeared in the state of the crispy rice, and then developed to the lens nucleus and cortex, resulting in a significant decrease in visual power. The

diabetic retinopathy

is caused by the long-term invasion of hyperglycemia, resulting in retinal capillary circulation disorder, slow blood flow, tissue hypoxia, capillary wall degeneration and brittleness, microangioma, punctate or flaky hemorrhage, cotton like exudation, and decreased vision. Further development of the disease, resulting in neovascularization due to hypoxia. If it is not treated in time, it will cause vitreous hemorrhage and reproductive retinopathy. Traction retinal detachment and secondary glaucoma lead to blindness.

and

, so once diabetes is diagnosed, besides strict control of blood sugar, it is necessary to check the eyesight regularly to ophthalmologists, check the lens with slit lamp microscope, expand the pupil to check the retina, so as to detect the lesion early and strive for early treatment, so as not to cause serious consequences. Diet should be strictly controlled, especially the elderly should eat less sweets, eat more vegetables and fruits, strengthen physical activities and have regular physical examination. If

,

,

and

have already suffered from diabetic cataracts and have serious effects on vision, they can remove opaque lenses and implant intraocular lenses under the condition of permission. As long as the fundus retina function is sound, satisfactory visual acuity can be obtained after operation.

and

early discovered that the retina had diabetic lesions. Laser coagulation could be used to close retinal neovascularization and microangioma, so as to improve retinal anoxia, prevent repeated bleeding, and prevent further loss of vision. If there is a large amount of hematocele or proliferative lesions in the vitreous, vitrectomy can only be used to prevent traction retinal detachment, but the prognosis is difficult to estimate.
