1. Are retinitis pigmentosa (RP) and retinal degeneration caused by high myopia the same disease? Is it wrong that many encyclopedias have the same explanation for retinitis pigmentosa and retinal degeneration? A: Retinitis pigmentosa (RP) and retinal degeneration caused by high myopia are not the same disease. There are many kinds of retinal degenerative diseases, and retinitis pigmentosa is only one of them, and most of them are hereditary diseases. Retinal degeneration caused by high myopia is mostly located in the peripheral retina, the exact name should be high myopia peripheral retinal degeneration area, these areas may occur in the future retinal fissures, and further cause retinal detachment, can use preventive retinal laser photocoagulation to reduce the risk of future retinal detachment. 2. Does retinitis pigmentosa inevitably lead to total blindness? A: Not necessarily. Retinitis pigmentosa is a large group of diseases, and there are hundreds of genes associated with retinitis pigmentosa, and each gene mutation causes different degrees of progression and severity. 3. Do all patients with retinitis pigmentosa develop night blindness in childhood and adolescence? If there is a family history of the disease, but no night blindness symptoms past the age of 30 can the disease be ruled out? What is the situation of a patient who develops it at age 40? A: Not necessarily. The answer is the same as question 2. 4. Does night blindness usually mean having RP? Does it then require a hospital visit? A: Night blindness includes two major categories, congenital and acquired. The congenital ones include retinitis pigmentosa, congenital stationary night blindness and several other diseases. The acquired ones are mainly due to vitamin A deficiency, diffuse chorioretinitis, choroidal atrophy, advanced glaucoma and other diseases. So if you have symptoms of night blindness you need to go to the hospital for further examination and clear diagnosis. 5. Is it also a symptom of night blindness in people with a family history of blurred vision in dimly lit places that requires further examination? A: It is best to go into the relevant examination to rule out the possibility of retinitis pigmentosa. 6. After retinitis pigmentosa is detected, why does the physician recommend a hearing check? A: There is a special type of retinitis pigmentosa disease: Usher syndrome, also known as retinitis pigmentosa-sensory deafness syndrome, which manifests as retinitis pigmentosa of the eye and neurological deafness in both ears. If the hearing test is abnormal, it is possible that this disease is present. 7. Which test is more sensitive, retinal current graph (ERG) or electrooculography (EOG) test? Is it possible to confirm the diagnosis of retinitis pigmentosa at an early stage? Can it be done in all patients? Is it very irritating to the eye? A: ERG is more important for the diagnosis of retinitis pigmentosa, as it can detect early night blindness. ERG is not very irritating to the eyes, and children over 6 years old are usually able to undergo the test.
