Abstract: in medicine, the optic disc is also known as the “optic nipple”, which is an important structure of people’s fundus. The so-called large optic disc depression refers to that a person’s eye cup and disc is obviously larger than ordinary people. Generally speaking, the normal person’s eye cup and disc ratio is ≤ 0.3. If it exceeds this value, it may be a large optic disc depression.
in addition to the fundus complications that may be caused by long-term high myopia such as macular disease and retinal detachment, some myopia patients found in their eye health examination report that they also had a large depression of the optic disc. Is this also the result of the disease caused by long-term myopia?
optic disc depression can be divided into physiological depression and pathological depression. If it is physiological depression, it will not cause any adverse impact on eye health, but if it is pathological depression, the doctor can suspect that it has glaucoma. Although the incidence rate of open angle glaucoma is high in the high myopia group, it does not mean that the occurrence of glaucoma is necessarily caused by long-term high myopia.
in medicine, the optic disc is also called “optic nipple”, which is an important structure of people’s fundus. The so-called large optic disc depression refers to that a person’s eye cup and disc is obviously larger than that of ordinary people. Generally speaking, the eye cup and disc ratio of normal people is ≤ 0.3. If it exceeds this value, it may be a large optic disc depression.
some people’s eyes naturally have physiological large depressions, just like some people are born tall and some people are born short. This depression will not have any adverse impact on their eye health, but the large depression of the optic disc is also an important feature of glaucoma. If a person finds his own large depression of the optic disc, he needs to see a doctor for intraocular pressure Vision Multiple examinations such as fundus stereogram (check retinal nerve fiber layer) to check any possible pathological changes, so as to verify whether they have glaucoma. Only when the possibility of glaucoma is really excluded can they be diagnosed as physiological optic disc depression.
Different from angle closure glaucoma, open-angle glaucoma has a hidden onset and is very difficult to be found in the early stage. Patients often find it too late. Moreover, it is a progressive disease. In the early stage of onset, small damage may not be detected by common clinical examination methods. Therefore, Li Shiming suggested that even people with large optic disc depression with negative glaucoma screening should be rechecked regularly to avoid delaying the early diagnosis and treatment of glaucoma.
