Did you know How is glaucoma diagnosed? Wonder about that? I guess only eye doctor can answer that. You can found many article about this. But i share you 2 way how glaucoma can be diagnosed.
An eye doctor (ophthalmologist) can usually detect those individuals who are at risk for glaucoma (because of, for example, a narrow filtering angle or increased intraocular pressure) before nerve damage occurs. The doctor also can diagnose patients who already have glaucoma by observing their nerve damage or visual field loss. The following tests, all of which are painless, may be part of this evaluation.
Tonometry determines the pressure in the eye by measuring the tone or firmness of its surface. Several types of tonometers are available for this test, the most common being the applanation tonometer. After the eye has been numbed with anesthetic eye drops, the tonometer’s sensor is placed against the front surface of the eye. The firmer the tone of the surface of the eye, the higher the pressure reading.
Pachymetry is a relatively new test being used for the management of glaucoma. Pachymetry determines the thickness of the cornea. After the eye has been numbed with anesthetic eye drops, the pachymeter tip is touched lightly to the front surface of the eye (cornea). Recent studies have shown that central corneal thickness can affect the measurement of intraocular pressure. Thicker corneas may give falsely high eye pressure readings and thinner corneas may give falsely low pressure readings. Furthermore, thin corneas may be an additional risk factor for glaucoma. treatment.
I believe you can will be more careful in future. So, be careful.
Eyeman - I hate glaucoma..
