Many diseases are easily confused with glaucoma, delaying the early detection and treatment of glaucoma, so they are listed for attention. A. Myopia Young people suffering from glaucoma are very likely to mistake it for myopia, and the first thing that comes to mind when they see something is to get glasses. The first thing that comes to mind is to get glasses. But when you wear glasses, you can’t see for long, so you think myopia is getting worse, and then you change your glasses. There are some characteristics of myopia: simple myopia stops developing at a certain age, but certain high myopia continues to develop with age for life, which is known as pathological myopia. As pathological myopia retina and optic nerve itself has some pathological atrophy changes, so that the early glaucoma and it is difficult to identify, until the late stage is easy to determine, so it is also one of the reasons why glaucoma is easy to miss misdiagnosis, high myopia people should be extremely careful. It is well known that when people get older, most of them will suffer from farsightedness, which is also commonly known as presbyopia. If the elderly do not read books and newspapers clearly, they think they are old-fashioned, with a presbyopic glasses or take a magnifying glass and can see clearly. This kind of self-solving method of unclear vision leaves a hidden danger for the development of glaucoma, especially the chronic development of glaucoma, which may not be visible one day. Therefore, it is necessary to go to the hospital to check whether the elderly people’s vision loss is presbyopia. Cataracts Another eye disease that the elderly are prone to is cataracts, which are more common in patients. Sometimes elderly people suffer from chronic glaucoma, and when they visit the hospital, they mainly have blurred vision. Individual doctors may misdiagnose glaucoma as senile cataract without a comprehensive examination, and even tell patients that they will be cured if they can’t see in the future through surgery. Clinically, there are many cases of misdiagnosis of glaucoma as cataract. This requires solid skills and rich experience of doctors, and patients can also consciously ask whether it will be glaucoma to remind doctors so as to avoid misdiagnosis. Fourth, migraine and acute gastroenteritis But when the intraocular pressure is very high, patients will have a headache and swelling and other feelings, many people will unconsciously close their eyes to rest when they are uncomfortable, and most of them will not realize that their vision has decreased, mistaking it for a migraine, taking some painkillers and forgetting about it, some of them will be better after a sleep and will relieve themselves. Some people with acute closed-angle glaucoma have high intraocular pressure, resulting in nausea and vomiting, which is mistaken for acute gastroenteritis. Once misdiagnosed as acute gastroenteritis, treatment with scopolamine drugs will cause pupil dilatation and aggravate the glaucoma condition. Therefore, if you have the above mentioned symptoms such as headache and vomiting, you should also check whether there is any problem with your glasses.
