Conjunctival impression cytology in computer users

Nepal J Ophthalmol. 2013 Jan-Jun;5(1):33-7. doi: 10.3126/nepjoph.v5i1.7819.

Abstract

Introduction: It is known that the computer users develop the features of dry eye.

Objective: To study the cytological changes in the conjunctiva using conjunctival impression cytology in computer users and a control group.

Materials and methods: Fifteen eyes of computer users who had used computers for more than one year and ten eyes of an age-and-sex matched control group (those who had not used computers) were studied by conjunctival impression cytology.

Results: Conjunctival impression cytology (CIC) results in the control group were of stage 0 and stage I while the computer user group showed CIC results between stages II to stage IV. Among the computer users, the majority ( > 90 %) showed stage III and stage IV changes.

Conclusion: We found that those who used computers daily for long hours developed more CIC changes than those who worked at the computer for a shorter daily duration.
