Purpose:  To determine the frequency of Dry eye in Glaucoma patients using topical anti-glaucoma therapy. Study Design:  Descriptive Observational study. Place and Duration of Study:  Study was conducted in outpatient department of Fatima Memorial Hospital Shadman, Lahore, from October 2016 to February 2017. Material & Methods:  In this study, 61 diagnosed cases of glaucoma were included. Patients with significant dermatological problems that may be associated with dry eye such as rosacea and blepharitis were excluded from the study. The individuals were assessed by consultant Ophthalmologist for Dry eye syndrome having symptoms of stinging and burning sensations itching, watering, irritation, due to regular use of topical anti-glaucoma drugs. A written consent was taken from every patient before the test. The ocular surfaces of the patients were evaluated using Tear film break-up time test and Basal Schrimer’s test. Patients having TBUT less than 11 seconds were categorized as having dry eye. The degree of dryness was categorized as mild, moderate and sever Dry eye. Results:  Among 61 patients of glaucoma using topical anti-glaucoma therapy, 22 (36.1%) were male and 39 (63.9%) were female. Mean age of the patients was 50.76 ± 15.67 years. On the basis of Tear film Break-up time test, 49 (81%) patients had Tear Break-up time less than 10 seconds and 12 (19%) patients were normal. On the basis of Schrimer`s test 51 (83.66%) patients had Dry eye. Conclusion:  Topical use of anti-glaucoma therapy affects tear film stability and its functions leading to Dry eye syndrome.

Abstract Pseudoexfoliation syndrome is an age related disorder, characterized by abnormal fibrous fiber production and accumulation in different visceral organs as well as in the eye and periocular tissues. Hystological examination recorded the presence of the pseudoexfoliation in the conjunctiva, and they can disturb the accessory lacrimal gland and goblet cell function. This can explain tear film instability in patients with pseudoexfoliations. In our study, we examined the tear film stability in patients with and without pseudoexfoliation, using Schirmer test and tear break up time test. Our results indicated that patients with pseudoexfoliation had lower values of Schirmer and tear break up time tests than patients without it. Pseudoexfoliation is the main reason for the instability of the tear film, because of its negative impact on the conjucntival goblet cells. In conclusion, ophthalmologists must have these data on their mind in the process of the pseudoexfoliation glaucoma treatment and controlling.

AbstractThe aim of the study was to analyze the correlation between the presence of Demodex mites in the hair follicles of patients' eyelashes and the stability and break up time of the tear film assessed with the Non-Invasive Tear Break Up Times (NIBUT) method. 319 patients were included in the study (195 women, 124 men). The patients were divided into two groups: those with Demodex infestation and without visible symptoms of eyelid or eye surface diseases, and asymptomatic non-infested patients. The NIBUT analysis was performed with a 5 M keratograph (oculus). Non-invasive tests were performed to identify the first and mean values of the tear break up time. The first and mean tear break up time in the Demodex-infested group was lower than in the non-infested subjects. The difference was a highly statistically significant. There was a significant correlation with the age of the patients for the first break up time. The first break up time in both eyes decreased with the age of the Demodex-infested and non-infested patients. The NIBUT analyses indicate the impact of Demodex mites on the tear film stability. This may suggest possible association of demodicosis with dry eye syndrome.
