Abstract

Purpose

To evaluate the cytologic features of conjunctival epithelium in patients with unilateral primary acquired nasolacrimal duct obstruction (PANDO) using impression cytology.

Methods

Twenty-four patients with unilateral PANDO for at least 1 year were enrolled in this study. The healthy eyes of the patients are assessed as control group. All patients were subjected to ophthalmic surface examination with conjunctival impression cytology analysis. Squamous metaplasia and goblet cell density were graded according to Nelson grading system.

Results

The mean age was 52.7 ± 16.3 (range 21–70) years. The mean period for complaints of epiphora was 3.2 ± 2.4 (range 1–8) years. The eye with PANDO had a mean squamous metaplasia grade of 2.38 ± 0.59 versus 1.91 ± 0.82 for control eyes (p = 0.011). The mean grade of goblet cell density was 2.0 ± 0.51 for eyes with PANDO and 2.38 ± 0.65 for control eyes (p = 0.013). There was no statistically significant correlation between conjunctival cytological features in terms of squamous metaplasia and goblet cell density grades and duration of epiphora complaint (r = −0.04, p = 0.82; r = 0.09, p = 0.66, respectively).

Conclusions

PANDO may cause alterations in conjunctival impression cytology. Successful dacryocystorhinostomy surgeries will help to protect ocular surface health.
