TEAR BREAK UP TIME IN PTERYGIUM

Dr. Abhishek Onkar

Abstract


Context: Tear film abnormalities have been incriminated in the symptomatology of Pterygium like dry eyes, burning
sensation and foreign body sensation.
Aims: To evaluate tear film break up time in patients with unilateral pterygium.
Settings and Design: Cross-sectional, case-controlstudy.
Methods and Material: Cross-sectional study of both eyes of 100 patients with unilateral pterygium was conducted
between March 2018 to April 2019.Patients were subject to fluorescein tear film break-up time (TBUT) analysis. The
normal eye acted as control and the results were subjected to statistical analysis.
Results: The study comprised of seventy males and thirty females in the age-range 28-76years. The mean TBUT was
7.8±1.2s and 12.4±1.8s in the eyes with pterygium and the normal eyes respectively.
Conclusions: The mean TBUT was found to be significantly decreased (p<0.01) in eyes with pterygium compared to
control eyes. This study thus emphasizes that tear film abnormalities play a role in the symptomatology of pterygium and
hence early institution of therapy for tear film stabilization can help prevent the morbidity related to disease.
