Glaucoma Symptoms and Signs
Patients with open-angle glaucoma and chronic angle-closure glaucoma in general have no signs early in the work of the disease. Visual field loss (side vision loss) is not a symptom until late in the work of the disease. Seldom patients with fluctuating levels of intra-ocular pressure may have haziness of vision and see haloes around lights, in the morning.On the other hand, the signs of acute angle-closure are often dramatic with the speedy onset of extreme eye pain, headache, nausea and vomiting, and visual blurring. Occasionally, the nausea and vomiting exceed the ocular signs to the extent that an ocular cause is not contemplated.
The eyes of patients with open-angle glaucoma or chronic angle-closure glaucoma may appear normal in the mirror or to relatives or friends. Some patients get slightly red eyes from the chronic use of eyedrops. The ophthalmologist, on examining the patient, may find elevated intraocular pressure, optic-nerve abnormalities, or visual field loss in addition to other less common signs.
The eyes of patients with acute angle-closure glaucoma will appear red, and the pupil of the eye may be large and nonreactive to light. The cornea may appear cloudy to the bare eye. The ophthalmologist will usually find decreased visual acuity, corneal swelling, highly elevated intraocular pressure, as well as a closed drainage angle.
