Abstract:
PURPOSE:Evaluation of contact lens-induced cytologic changes on the conjunctival surface. METHODS:Fifty eyes of 25 patients wearing soft or rigid gas-permeable contact lenses, and 50 healthy eyes of 25 control subjects were examined with conjunctival impression cytology. Of the patients wearing contact lenses, 40% did not have any contact lens-related complaints, whereas 60% had some minor complaints related to contact lens intolerance. The material obtained by impression cytology was examined with regard to epithelial cell morphology, goblet cell density, and snake-like nuclear chromatin changes. RESULTS:When epithelial cell morphology was graded according to the system described by Nelson, specimens from the control group revealed 90% of the eyes to be grade 0 and 10% to be grade 1, whereas of the eyes wearing contact lenses, 8% were grade 0, 36% grade 1, 32% grade 2, and 24% grade 3. Thus statistically significant differences were observed between the control group and the contact lens group with regard to each grade (p < 0.05) as well as to the goblet cell densities (p < 0.05). Snake-like chromatin changes, on the other hand, were observed in 30 and 27% of the eyes wearing soft and rigid gas-permeable contact lenses, respectively, whereas these were not encountered in any eye in the control group. CONCLUSION:Epithelial changes were noted to be more frequent and more severe in symptomatic patients than in those without any complaints. No correlation was found between average duration of contact lens wear and the risk of contact lens intolerance or development of squamous metaplasia.
