Back to Health A to Z. Glaucoma is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged. It's usually caused by fluid building up in the front part of the eye, which increases pressure inside the eye. It tends to develop slowly over many years and affects the edges of your vision peripheral vision first.
Systemic hypertension associated with primary open angle glaucoma
T his case study is an example of how meticulously and elegantly we can identify structural and functional defects by incorporating more than one imaging modality when diagnosing glaucoma patients. In this case study, however, the lesson is two-fold. A large part of the challenge associated with managing glaucoma patients is convincing them to comply with their treatment regimens. This case study also serves as an example of how imaging allows me to educate patients about their condition and progression. These visuals are easily understood by patients and encourage them to adhere to their treatment and, ultimately, improve their disease. A year-old female presented to my clinic for glaucoma consultation. The highest IOP that had been recorded throughout her prior history was 22 mmHg.
Aqueous is made in a ring of tissue that sits behind the iris called the ciliary body. It then flows through the pupil and drains away through tiny channels called the trabecular meshwork. The trabecular meshwork is found in the angle between the cornea and the iris often called the drainage angle. In a normal eye, there is a balance between inflow and outflow of fluid, but in some eyes this balance is disturbed, and this causes the eye pressure to rise. In most cases of POAG, the problem occurs due to the fluid outflow not working as well as it should.
Purpose: To examine the factors associated with blindness from primary open-angle glaucoma POAG among black and white patients at our institution. Patients and methods: For this retrospective, case-control study, patients legally blind from POAG "cases" were matched on age, race, and gender with non-blind POAG patients "controls". Thirty-seven black case-control pairs and 19 white case-control pairs were included in this study. Clinical variables were compared at initial presentation and over the course of follow-up.
