Patient: Small pupils and low vision, the child was once seen in the ophthalmology department of Tong Ren Hospital when it was discovered at about one week and the dilated pupils were not obvious, because the child was found to have congenital kidney disease at three weeks, so he did not seek medical attention again, I wonder if these are related. Please help prompt me how to give my child a job. Laboratory and examination results: The result of the machine examination of vision is high myopia, more than 1200 degrees, the last hospital visited: Tong Ren Hospital. Pang Lin, Strabismus and Pediatric Ophthalmology, Peking University First Hospital: As long as the pupil transmits light well, the size has little effect on vision, and a relatively small pupil in myopic people can be a normal phenomenon. However, if the pupil is congenitally atretic or severely deviated, surgery is required. Patient: Thank you, doctor! So how can I check the translucency? Can such high myopia be adjusted? What should I do? Pang Lin, Strabismus and Pediatric Ophthalmology, Peking University First Hospital: You can see your doctor to determine whether the pupil is translucent. High myopia can be better with RGP contact lenses.
