The Nighttime Blood Pressure Dip: A Hidden Driver in Normal-Tension Glaucoma Normal-tension glaucoma (NTG) is a type of glaucoma where the optic nerve deteriorates even though eye pressure is normal. In NTG, experts believe blood flow to the optic nerve plays a key role. The ocular perfusion pressure (OPP) – roughly the difference between blood pressure in the eye’s vessels and the eye’s internal...
Glaucoma progression means the gradual worsening of damage to the optic nerve that carries visual information from the eye to the brain. In many cases this damage leads to loss of side vision first and can eventually affect central vision if not controlled. Progression is tracked with tests that measure visual fields and with imaging that looks at the nerve and retina, so doctors can see small changes over time. The course can be slow or relatively fast, and different people experience different rates of decline. Because early stages often have no noticeable symptoms, regular testing is important to catch progression before significant vision is lost. Factors such as eye pressure, blood flow to the eye, family history, and other health conditions can influence how quickly the condition advances. When progression is detected, doctors can change or intensify treatment to try to slow or stop further damage. The goal is to preserve as much vision and quality of life as possible, so monitoring and timely treatment decisions matter a great deal. Understanding progression helps people and their doctors make informed choices about follow-up, lifestyle steps, and therapies to protect sight.
