The retina is a thin film inside the eyeball that converts light into nerve signals that are transmitted to the brain for interpretation. The retina is filled with photoreceptor cells, including cones and rods, which differ in their sensitivity to light, allowing us to see the world in different light conditions. Retinal disorders occur when these cells are damaged or diseased.
When there is a retinal disorder, how is our vision affected?
Visual field defects:Retinal disorders can lead to blind spots in the visual field, where people are unable to see objects in certain areas. This defect may be localized or extensive, severely affecting the patient's daily life.
Vision loss:Retinal disorders are often accompanied by symptoms of vision loss. People may experience blurry, unclear vision, and in severe cases, blindness.
Color perception is abnormal:Retinal disorders can also affect the perception of color. People may find that the colors they see don't match their reality, or they may not be able to distinguish certain colors.
Night blindness:If retinal disorders affect rod cells, people may develop symptoms of night blindness, which is a marked decrease in vision at night or in dark environments.
Approaches to retinal disorders vary depending on the specific condition, but typically include the following main strategies:
Medications**:For retinal damage caused by contusion or external factors, glucocorticoids can be used to reduce retinal edema and protect visual function; For retinal damage due to photochemical injury, neurotrophic drugs and vitamins may be needed; At the same time, drugs that improve microcirculation and antioxidative stress** are used according to the specific situation, which can reduce the high viscosity of the blood, reduce the leakage of retinal microvessels, and help restore retinal function.
Surgery**:For retinal detachment caused by trauma or high myopia, timely surgery, such as laser surgery, cryotyping**, pneumatic retinopexy, etc., is required to repair the retinal tear, reduce retinal traction, and reattach the detached retina to the eye wall.
Laser**:Laser** is commonly used for retinal vascular lesions, such as diabetic retinopathy or retinal vein occlusion. Lasers can also be used to close retinal tears.
Auxiliary**:Increase rest time and avoid staying up late for long periods of time to reduce irritation of the retina; Warm compresses can promote the blood flow velocity in the eye area, which can help improve symptoms such as eye soreness and pain caused by retinopathy; Follow a healthy diet with fresh vegetables, vitamin-A-rich fruits, etc., and avoid smoking and alcohol.
Note that the method should be determined based on the patient's specific condition and the doctor's recommendations. It is very important to maintain close communication with the ophthalmologist and follow the doctor's protocols and recommendations during the process. Through scientific management and management, we can minimize the impact of retinal disorders and protect our visual function.
