Objective: To evaluate tear functions in patients with pterygium and pingueculae.
Materials and Methods: 22 eyes of 15 patients with pterygium and 24 eyes of 14 patients with pingueculae were evaluated for Schirmer test, corneal tear film break up time (BUT) and tear meniscus height (TMH). The results were compared with 26 eyes of 13 healty subjects.
Results: The mean Schirmer test values were 11,68±5,11; 10,00±6,75; 15,50±4,90 mm in patiens with pterygium, pingueculae and in controls respectively. When compared with control group Schirmer test results were significantly decreased in patiens with pingueculae (p=0,03). The mean BUT values were 8,68±3,74; 9,12±6,38; 14,9±6,69 seconds in pterygium, pinguecula and control groups respectively. Mean BUT values was significantly reduced in the pterygium and pingueculae groups (p=0,01, p=0,02). Mean TMH values were 1,09±0,54; 1,02±0,61; 1,46±0,60 mm in pterygium, pingueculae and control groups respectively. In pinguecula group TMH was significantly reduced. Between pterygium and pinguecula groups Schirmer test, (p=0,574), BUT (p=0,96) and GMY (p=0,911) values were not different.
Conclusion: Pterygium and pinguecula change tear functions.
