Rat nerve growth factor is useful in optic nerve atrophy caused by glaucoma, but does not cure glaucoma. The ultimate goal of glaucoma treatment is to lower intraocular pressure, thereby reducing damage to the optic nerve and protecting existing vision or delaying vision loss. Rat Nerve Growth Factor is a nerve growth factor, which mainly works to nourish nerve cells and promote the repair of nerve cell function. Therefore, it has some curative effect on optic nerve atrophy caused by glaucoma, but it is not difficult to cure glaucoma. Glaucoma is a class of diseases manifested by pathologic increase in intraocular pressure, accompanied by damage to the optic nerve and visual field, and patients may suffer from decreased visual acuity, visual field defects, and even blindness. Patients with glaucoma are advised to seek timely medical attention to assess their condition and undergo treatment under the guidance of a medical professional.
