Patient tolerance and ocular surface staining characteristics of lissamine green versus rose bengal.

Abstract

PURPOSE:

To determine patient tolerance and ocular surface staining characteristics of 1% lissamine green versus 1% rose bengal solutions in patients with dry eye and in those with normal ocular surfaces by comparison of subjective sensation and objective staining scores.

METHODS:

Twelve patients with keratoconjunctivitis sicca and eight subjects with no ocular surface disease recorded their symptoms on a graded scale (0-5) and the duration of symptoms after instillation of one drop of 1% lissamine green and 1% rose bengal on two different occasions in different order. Lissamine green and rose bengal staining patterns were recorded on a graded scale (0-4) by one of the authors.

RESULTS:

For patients with keratoconjunctivitis sicca mean sensation score with lissamine green (2.42) was significantly lower (P = 0.00006) than with rose bengal (4.58). The duration of symptoms was significantly longer (P = 0.0007) after rose bengal instillation as well. For subjects with no ocular surface disease, mean sensation score with lissamine green (1.375) was significantly lower (P = 0.01) than with rose bengal (2.5). In this group, duration of symptoms also was significantly longer (P = 0.001) after rose bengal instillation. In both groups, there was no difference in objective staining scores.

CONCLUSION:

Lissamine green is better tolerated than rose bengal by patients and is equally as effective as rose bengal in evaluating the ocular surface in keratoconjunctivitis sicca.
