1. What is the abnormal IOP? Answer: The normal IOP value is 10-20 mmHg. Children with IOP higher than this value need to be alerted. 2.What is the worst case of high IOP? Answer: It is glaucoma. A chronic eye disease that can cause blindness. 3.What are the symptoms of glaucoma in children? Answer: Most early glaucoma in infants and young children, as well as in adolescents, does not have any symptoms. 4. Can dilated pupils cause glaucoma in children? Answer: Not usually. However, there is one type of glaucoma that cannot be dilated: closed-angle glaucoma. Dilated pupils can cause acute attacks of closed-angle glaucoma. Closed-angle glaucoma in children is extremely rare. 5. How is glaucoma in children caused? Answer: Glaucoma in children (including juvenile glaucoma) is usually due to a genetic abnormality, but the duration of onset varies. So children with a family history of glaucoma need to be checked early. Some children have used hormones (including oral, infusion, and topical) for treatment purposes, which may cause hormonal glaucoma. Eye trauma. 6. Is high intraocular pressure glaucoma? Answer: Not necessarily. Factors of pseudo-intraocular pressure elevation include: tension, squeezing eyes during measurement, crying, thick and hard sclera or cornea. 7. How can high IOP be differentiated from glaucoma? A: If there is elevated IOP combined with “progressive atrophy of the optic nerve”, it can be identified as glaucoma. Since optic nerve atrophy usually occurs in the late stage of the disease, some modern tests: OCT, visual field, electrophysiology, etc. help us to detect glaucoma earlier. 8. How should glaucoma be treated if found? Answer: In a word: early treatment. Glaucoma is a chronic eye disease and most of them require lifelong treatment and follow-up. However, if it can be detected and treated early, it can preserve vision to the maximum extent. With the development of technology, more and more means of treatment (including drugs and surgery) are available. It is believed that more and better technologies will be available for treatment in the future.
