Measurement of Intraocular Pressure
With the patient’s eyes closed, the examiner places his or her hands on the patient’s head and palpates the eye through the upper eyelid with both index fingers (Fig. 1.15). The test is repeated on the contralateral eye for comparison.
A “rock hard” eyeball only occurs in acute angle closure glaucoma. Slight increases in intraocular pressure such as occur in chronic glau-coma will not be palpable.
