Predictive factors for progressive optic nerve damage in various types of chronic open-angle glaucoma.
OBJECTIVE
To evaluate whether various types of chronic open-angle glaucoma differ in predictive factors for progression of glaucomatous optic nerve damage.


METHODS
Observational cohort study.


METHODS



METHODS
Prospective observational clinical study.


METHODS
517 eyes of 300 Caucasian patients with chronic open-angle glaucoma with elevated intraocular pressure (primary open-angle glaucoma, n = 289; secondary open-angle glaucoma, n = 50) and with normal intraocular pressure (n = 178).


METHODS
During follow-up (median: 49 months, 6 months-130 months), all patients underwent repeated evaluation of color stereo optic disk photographs and white-on-white visual field examination.


METHODS
Progression of glaucoma was defined as neuroretinal rim loss during the study period.


RESULTS
For patients with elevated intraocular pressure, significantly predictive factors for eventual progression were older age, advanced perimetric damage, smaller neuroretinal rim, and larger area of beta zone of parapapillary atrophy. In contrast, in the normal intraocular pressure group, a significant predictive factor was presence of disk hemorrhages at baseline. Within the patients with elevated intraocular pressure, the primary open-angle glaucoma group and the secondary open-angle glaucoma group did not differ in predictive factors for progression of glaucoma.


CONCLUSIONS
Open-angle glaucoma patients with normal intraocular pressure and open-angle glaucoma patients with elevated intraocular pressure differ in predictive factors for eventual progression of glaucomatous optic nerve damage. It may have clinical importance and may be helpful in the discussion of the pathogenesis of the glaucomas.
