Intra‐ocular pressure (IOP) is the only modifiable risk factor for glaucoma and sensitive to various hemodynamic changes in the body. Thankfully, with the advent of multiple anti‐glaucoma drugs, IOP lowering has become an achievable task, yet almost every medication has some local and systemic side effects, which make the patient wary of using these medications. Glaucoma, being the most common cause of irreversible blindness, has a tremendous effect on the psychosocial well‐being of the patient. In 10% of cases, glaucoma progresses despite low IOP, which implies the role of other factors such as low ocular perfusion pressure (OPP) in causation of glaucoma.[1] Nevertheless, IOP still remains the only treatable entity in management of glaucoma.
