Can night blindness see clearly during the day?
Night blindness is mainly due to two types of cells on our retina: cone cells and rod cells. Rod cells are responsible for vision at night, while cone cells are responsible for vision during the day and are crucial for sharp vision. In cases of night blindness, there are issues with the rod cells, but patients also have problems with their cone cells. Therefore, not only is their nighttime vision unclear, but their daytime vision is also worse than that of an average person. Although they can see during the day, the clarity is impaired. This condition is primarily due to a genetic anomaly, often involving a chromosomal abnormality. It is recommended that patients supplement with B vitamins, such as lutein.
Will night blindness lead to blindness?
Night blindness first requires determining the cause of your condition. If it is due to a deficiency of vitamin A leading to night blindness, supplementing vitamin A can alleviate the symptoms, and the night blindness will disappear. However, if the night blindness is caused by retinitis pigmentosa, as this condition progresses with age, the symptoms of retinal pigment degeneration worsen and the retinal-caused night blindness will gradually intensify, eventually there is a possibility of blindness. It is essential first to determine the specific cause. Some people may experience a rapid progression of the disease, but others with retinitis pigmentosa, or such symptoms of night blindness, may not be very severe. They could maintain useful vision throughout their lives, which mainly depends on the type and severity of the genetic mutation and the specific causes.
How many days does retinal detachment surgery take?
Retinal detachment surgery is divided into internal and external approaches. Generally, the surgery takes about one to two hours, or two to three hours. One method involves compressing from the outside of the eardrum, pushing the eardrum inward to reattach the retina, while the other involves operating from inside the vitreous body outward to adhere the retina to the choroid. The recovery time for these surgeries generally reaches a stable condition from one to three months. The duration of the surgery depends on the complexity of the condition; it can be as quick as just over half an hour in simple cases, or up to two to three hours in complex cases. Postoperative vision recovery primarily depends on the duration and morphology of the retinal detachment, as well as the proliferation conditions of the detached retina and the vitreous body.
