Early symptoms of glaucoma:
A, eye swelling, headache, blurred vision, especially in emotion or in the dark stay too long (such as angry, watching movies on TV or in the darkroom work), the above symptoms can appear, after a rest can alleviate the symptoms of glaucoma, seizures also known as glaucoma. Repeatedly appears, there may be severe eye pain, headache, visual acuity decreased sharply, with nausea, vomiting and other symptoms, sometimes misdiagnosed as acute gastroenteritis and cerebrovascular disease.
Two, premature presbyopia, such as 40 years ago (presbyopia presbyopia but to appear earlier and longsighted differentiated), especially women, presbyopic glasses degree of change quickly, need frequent replacement of glasses, indicating that the loss associated with eye adjustment, it is directly proportional to the degree of early lesions of glaucoma.
Three, the gradual decline of eyesight, optometry visual acuity less than 1 (logarithmic visual acuity chart for 5), especially in high myopia, wearing appropriate glasses still often have headaches bulging eyes. Due to high myopia sclera long elastic decreased, when the high intraocular pressure, symptoms not obvious or not the symptoms can not cause patients to pay attention, the doctor also missed, and the damage of visual function is more and more serious. (visual impairment include decreased visual acuity, reduced vision, etc.)
Four, look at the rainbow lights at night, there is a riot of colours in halo lights like after the rainbow in the sky. This is due to increased intraocular pressure, corneal edema caused by corneal refractive change.
Five, if you drink too much water (such as drinking more than 300ml at a time), you will notice eye swelling and headache after drinking 15--30 minutes. This is because the speed of drinking water is fast and the volume is large. It can reduce the osmotic pressure caused by blood dilution and increase the number of aqueous humor entering the eyes, resulting in the increase of intraocular pressure.
Six, the morning after reading, reading newspapers is difficult, there is nasal root soreness and orbitofrontal pain, this is because the normal intraocular pressure with diurnal fluctuation, generally high and low in the morning and night, 24 hours intraocular pressure glaucoma patients greater volatility, so the morning intraocular pressure is higher, and the the symptoms.
If the patient has the early symptoms of glaucoma, he should check with the ophthalmologist in time to see if he has glaucoma, so that he can detect and treat early, so that we can improve the therapeutic effect on glaucoma and minimize the risk of blindness.
