Glaucoma is an eyesight ailment characterized by an increase of pressure of the fluid within the eyeball. This increased pressure causes abnormal changes in the optic nerve and defects in the field of vision.
Dave, I seem to have higher IOP on stressful days and weight lifting days.
My wife lost sight in her right eye 6 years ago due to post operative glaucoma following macular hole surgery. She has now developed a macular hole in the left eye and will have to ungergo the same surgery. We want to do everything possible to make the same outcome less likely.
I have been reading the FitEyes posts for a long time now—hoping that I could get some ideas of how to preserve my vision in my only good eye. Here is a little of my history. I was diagnosed with glaucoma in 1989. I can’t even remember what the pressures were at that time because I had no frame of reference. All I know is that about four years later I had ALT laser to both eyes, and the doctor was gratified that he was able to get the pressure down to 18. It didn’t last, but it was an initial victory. Other than the short time after the laser, my pressures ran around 30 in both eyes.
Millions of people around the world should be monitoring their eye pressure (intraocular pressure) at home, according to health organizations (such as International Society for Self-Tonometry (ISST)) that are issuing recommendations on what to do and how to do it. Many experts, such as Dr.
Author’s Note: I have been practicing self-tonometry now for about three weeks with a Reichert 7 NCT.
For the past 9 years, I have been supplementing with glucosamine chondroitin to ward off joint issues due to an intense daily exercise regimen. I’ll never know for sure whether this supplement works as advertised since I began taking it as a preventative measure and to this day do not suffer from joint pain. However, when I read recently on the internet that chondroitin can possibly make matters worse for glaucoma patients, I dropped the supplement overnight and did not wean myself off it. This action may have led to the unintended result which I describe below.
Glaucoma is the leading cause of irreversible blindness in the world. Diagnosis and management of glaucoma is significantly associated with intraocular pressure, but contemporary office-based measurements are not sufficient to discover diurnal changes and spikes, nor do they demonstrate the effect of medication and compliance. Patient-directed self-tonometry can be taken throughout the day and is therefore the subject of much discussion and research. In this article we review the history of self-tonometry devices and present technologies for the future.

Purpose: To assess the dose-response relationship of vigorous physical activity (running distance, km·d-1) or cardiorespiratory fitness (meters-per-second pace during a 10-km footrace) to the risk for incident glaucoma.
Conclusions: These data provide preliminary evidence that vigorous physical activity may reduce glaucoma risk, which, in the absence of medical record validation, could represent ocular hypertension in addition to frank glaucoma. Additional follow-up with validation is needed to identify the type of glaucoma affected.

Background
With the increasing number of people participating in physical aerobic exercise, jogging in particular, we considered that it would be worth knowing if there are should be limits to the exercise with regard to the intraocular pressure (IOP) of the eyes. The purpose of this study is to check IOP in healthy and primary glaucoma patients after aerobic exercise.
