SUMMARY
Glaucoma at tlie Outpatient Department,
St.Joseph’s Hospital, Reykjavík Iceland
This article is a review of the cases of glaucoma
treated at the Glaucoma Clinie, St.Joseph’s
Hospital, Reykjavík, Iceland, over a period of 5
years and 3 months. At the end of 1978, 624
cases with open angle glaucoma, 7 closed angle
glaucoma patients and 124 glaucoma suspects
underwent an ophthalmic evaluation.
The majority of the open angle glaucoma
patients are elderly, 76% are 67 years and
older.
There are relatively fewer individuals in the
younger age groups in this study than in the
former studies in this country, which date back
to the turn of the century. The extent to
which maies outnumer females in the former
studies is very striking. In the present study
the sex distribution is more even, 52% of the
patients are males and 48% are females.
Environmental factors that might have
changed the course of the disease are discussed.
It is estimated that about 50% of open angle
glaucoma patients in Reykjavík and suburbs
are under treatment at the glaucoma clinic,
that is, if the overall prevalence rate is similar
to that found in the Framingham Eye study
in USA. A recent population study of potential-
ly blinding diseases indicated that the preva-
lence rate of glaucoma in Iceland and USA are
almost identical.
One third of the glaucoma patients had only
„blind spot“ enlargement and depression of
central isopters (tested on Goldmann’s peri-
meter), as their only visual field abnormalities.
This is the same percentage as found in the
Framingham study. The visual field defects are
more advanced among males, esp. in the older
age groups. About 15% of the total eyes of
males had reached the terminal stage, com-
pared to 7.6% among females. 83% of the open
angle glaucoma cases had visual acuity 6/6—
6Í/15 of the better eye.
Other eye diseases among the glaucoma
patients are cataracts or aphakia (37.5% males,
40.9% females) and senile macular degenera-
tion (3.7% males and 7.3% females). Only 3
of the glaucoma cases had diabetes.
Filtrating operations and other operations
to lower intraocular pressure have been done
on 30% of all glaucoma eyes (males 37.6%,
females 21.6%).
Follow up cases of glaucoma suspeets are
discussed.
