Abstract

PURPOSE:

Cytokines have been implicated in corneal inflammatory diseases. The authors sought to determine if corneal diseases with different patterns of inflammation are accompanied by characteristic patterns of cytokine expression.

METHODS:

The authors used reverse transcription-polymerase chain reaction to detect mRNA for 12 specific cytokines from patients with Fuch's dystrophy (n = 7), pseudophakic bullous keratopathy (n = 12), or normal corneas (n = 4).

RESULTS:

Using Wilcoxon rank sum analysis, mRNA for interleukin (IL)-1 alpha or IL-8 was significantly more abundant in corneas from patients with pseudophakic bullous keratopathy relative to either comparison group. mRNA for the T-cell marker, CD4, and for T-cell derived cytokines, IL-2, IL-4, and interferon gamma, could not be detected in any corneal sample. Message for IL-1 receptor antagonist and transforming growth factor-beta 1 or -beta 2 was readily detectable in most corneas regardless of diagnosis.

CONCLUSION:

The findings indicate that the pattern of cytokine mRNA expression reflects differences in the pathogenesis of these corneal diseases.
