Aim: To determine the prevalence of dry eye in glaucoma
patients using topical anti-glaucoma therapy.
Design: Descriptive observational study
Place and duration
of study: Department of Ophthalmology, Shalimar Medical
& Dental College Lahore from 1st November 2020 to 30th
Ninety patients of both genders were
enrolled. Detailed demographics of enrolled cases age, sex and body mass index
were recorded after taking informed written consent. Patients using topical
anti-glaucoma therapy for more than 8 months and having symptoms of stinging
and burning sensations itching, watering, irritation, due to regular use of
topical antiglaucoma drugs were presented. Basal Schrimer’s test and tear film
break-up time test was used to measure the frequency of dry eye syndrome as
mild, moderate and severe.
Results: There were 60 (66.7%) females and 30 (33.3%) patients
were males. Mean age of the patients were 45.61±7.66 years with mean BMI
26.24±8.71 kg/m2. We found that 40 (44.4%) patients had burning and
stinging sensations, itching found in 21 (23.3%), dry eye sensations were found
in 16 (17.8%) patients and watering and irritation found in 13 (14.4%)
.According to tear film break-up time test 20 (22.2%) cases did not show dry
eye syndrome and 19 (21.1%) patients were normal in Basal Schrimer’s test.
Conclusion: Use of topical anti-glaucoma medication resulted in dry
eye syndrome as well as a decrease in the tear film's stability.
