2. Match the following findings with the above landmark glaucoma
||This study compared the effect on progression of early diagnosed open
angle glaucoma of immediate treatment (ALT and Betaxolol) versus no treatment.
The study showed a mean IOP reduction of 25% was associated with a 27.4%
reduction in risk of disease progress. Each 1 mmHg lowering of IOP correlated
to a 10% risk reduction.
||This study assessed the effect on early diagnosed open angle glaucoma
patients of initial therapy with either topical medications or with trabeculectomy.
After 5 years of follow-up, both medical and surgical intervention were
shown to be equally effective in reducing IOP and preventing vision loss.
||This randomized study looked at the effect of lowering IOP medically
on the onset of visual field defects in ocular hypertensive patients. The
study concluded that active treatment more than halved the risk of developing
primary open angle glaucoma over the 5-year follow-up.
||This long-term study looked at the relationship between IOP and visual
field deterioration after surgical intervention for glaucoma. The study
showed that maintenance of IOPs at less than 18mmHg resulted in stable
visual fields throughout the 6-year study.
||This randomized study looked at the effect on normal-tension glaucoma
of surgically or medically lowering IOP by 30% from baseline (compared
to untreated control group). The study showed that of IOP normal-tension
glaucoma patients reduction significantly reduced disease progression.
