To Compare Changes of Tear Film Function in Patients with Pterygium before and after Pterygium Excision Combined with Limbal-Conjunctival Autograft Transplantation
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 5
Abstract
Introduction: Pterygium is associated with tear instability which is a disorder of tear film. Tear instability leads to dry eye which causes vision threatening complications. Thus a prospective interventional study was done to compare changes of tear film function in patients with pterygium before & after pterygium excision combined with sutureless & glue free limbal-conjunctival autograft transplantation. Material and Methods: The study was conducted at postgraduate upgraded department of Ophthalmology of GMC Jammu over period of one year. 90 patients having unilateral primary pterygium presenting to the eye OPD of GMC Jammu were included in the study. The TBUT, Schirmer’s test & basal tear secretion/SCH- 2 were estimated in all patients in normal eye & in pterygium eye both preoperatively & 2 months postoperatively. A TBUT of less than 10 seconds, a Schirmer’s test of less than 10mm, basal tear secretion of less than 10mm were considered abnormal. Pterygium excision combined with sutureless & glue free limbalconjunctival autograft transplantation done in all patients. Results: Compared with the opposite healthy eyes, the TBUT & Schirmer’s test in the eyes with pterygium were significantly different before operation (p < 0.0001) while no significant difference seen post-operatively. However in eyes with pterygium the results were significantly different before & 2 months after the operation (p < 0.0001). Conclusion: Tear film functions improves after pterygium excision indicating that pterygium contributes to the phenomenon of disturbed tear film functions.
