| Summary: |
Purpose: Laser
iridotomy (LI) is the standard procedure to relieve
relative pupillary block in patients with narrow
occludable filtration angles. We have observed a
difference in response to this procedure in declared
Hispanic and Caucasian patients. In this study an
attempt is made to compare the effectiveness of an LI in
this two ethnic groups.
Material and methods: In a prospective study an
LI was performed in 21 (42 eyes) Hispanic and 14 (23
eyes) Caucasian patients with narrow, occludable
filtration angles. A standard clinical examination along
with evaluation of the filtration angles (goniscopy and/or
ultrasound biomicroscopy) was performed in each patient
before and after the LI.
Results: Age range for Hispanic patients was 47
to 83 (mean 66) years, 37 to 76 (mean 57) years in
Caucasians. Non-occludable filtration angles following
LI were observed and documented in 17/36 eyes (47.2%) of
Hispanic and 17/23 eyes (73.9%) of Caucasian patients.
Those with plasteau iris syndrome were similarly
compared: 2/4 eyes (50.0%) in Hispanics and 9/12 eyes
(75.0%) in Caucasians were non-occludable after LI. The
remaining patients with occludable filtration angles
form causes other than plateau iris, responded
positively to LI in 15/32 eyes (46.9%) in the Hispanic
cohort, and 8/11 eyes (72.7%) in the Caucasian.
Conclusions: Non-occludable filtration angles
following LI are achieved more frequently in Caucasians
when compared with Hispanics. |
