A method of treating glaucoma or other eye disease in a patient is provided. The method includes injecting an eye of the patient with a cohesive monophasic gel containing cross-linked hyaluronic acid or its salt. The injection can be under the scleral flap and/or conjunctiva of the eye, thereby creating and maintaining a conjunctival bleb, and/or the injection can be in the supra-scleral and/or supra-choroidal (sub-scleral) space of the eye thereby reducing the intraocular pressure.
