Management and prognosis of end-stage glaucoma.
OBJECTIVE
We followed, for a long term, end-stage glaucoma patients as defined by the level of legal blindness.


METHODS
Follow up was for 7.7+/-1.8 years (range 2-9) for 22 patients (13 men and nine women) having 32 eyes with functional vision. Age at exit was 74.6+/-15.5 years (range 33-89). Humphrey computerized perimetry and applanation tonometry were used throughout. We attempted to hold intraocular pressure below 15 mmHg using as much medical therapy as required.


RESULTS
All visual fields were less than 10 degrees diameter at exit, but at entry seven eyes of six patients still had a field between 10 degrees and 20 degrees, the rest were all less than 10 degrees. Corrected visual acuity at entry was 6/9 to 6/6 in 21 eyes of 6 patients and none had less than 6/60. At exit 16 eyes had 6/9 to 6/6 and five eyes had less than 6/60, but no patient had complete loss of vision. Mean intraocular pressure (IOP) throughout was below 15 mmHg in all but four patients, whose (IOP) were less than 20 mmHg, using multiple medications if necessary. All patients had undergone prior surgery and/or laser trabeculoplasty.


CONCLUSIONS
Even though visual loss slowly progressed, most patients with end-stage glaucoma retained functional vision for a long period when intraocular pressure was held below 15 mmHg. More stringent early control of intraocular pressure may avoid the development of end-stage glaucoma.
