Doctor, my vision is still 1.0, how did it become late stage glaucoma? "" I heard that normal eye pressure means everything is fine, right March 6th is World Glaucoma Day. Wen Ye, the director of the inpatient department of Guangzhou Purui Eye Hospital, stated on March 5th that glaucoma does indeed cause blindness and the damage is irreversible. But as long as early detection, standardized treatment, non discontinuation of medication, and non adherence to folk remedies are achieved, the vast majority of patients can "lock in" their condition and preserve their remaining vision through pressure control. In clinical consultations, Wen Ye found that many patients have deep-rooted misconceptions about glaucoma. It is these misconceptions that lead many people to miss the best intervention opportunity, and by the time obvious symptoms appear, their visual function has suffered irreparable damage. Is normal eye pressure glaucoma? Wen Ye said that many people mistakenly believe that "glaucoma=high intraocular pressure". In fact, the essence of glaucoma is optic nerve damage. Some individuals may experience optic nerve atrophy due to extreme fragility, even if their intraocular pressure is within the statistically normal range. Therefore, checking intraocular pressure alone is not enough, it must be combined with fundus examination and visual field testing. Is there no glaucoma with a visual acuity of 1.0? Glaucoma focuses on blind spots in the visual field. The visual field defect in most glaucoma patients is a slow, gradual, and irreversible process that progresses gradually from the periphery to the middle, making it difficult to notice in the early stages. Some patients with advanced glaucoma may have a central visual acuity of 1.0, but their field of view is only "tubular". So, while paying attention to vision, it is also important to monitor changes in the field of view. As long as you are young, you won't get glaucoma? People of any age are likely to suffer from glaucoma. The older the age, the higher the incidence rate. There are many types of glaucoma, which can generally be divided into primary and secondary types. Primary glaucoma can be further divided into angle closure and angle opening types. Closed angle glaucoma is more common in the elderly, while open angle glaucoma patients are relatively younger, while congenital glaucoma and developmental glaucoma occur earlier. Regarding daily eye care, Wen Ye suggests being alert to "eye distress signals": if there is frequent eye swelling, rainbow circles (rainbow vision) when looking at lights, severe eye pain and headache, reduced field of view, or difficulty seeing clearly after frequently changing reading glasses after the age of 40, it should be promptly investigated. At the same time, get rid of bad eye habits, refuse to use your eyes in dark environments, especially do not turn off the lights and play with your phone; Manage emotions well and avoid long-term anxiety and impatience; Rest for 5-10 minutes every 30-40 minutes of eye use; Avoid looking down, bending over, or wearing sunglasses for too long. In addition, regular specialized screening should be conducted. Wen Ye suggested that people over 40 years old should have their fundus and intraocular pressure checked once a year; For high-risk groups with high myopia, diabetes and family history of glaucoma, the screening age should be advanced to 35 years old.
