title: Ocular cicatricial pemphigoid associated with hyperproliferation of the conjunctival epithelium.
abstract: We determined the mitotic rate, measured by evaluating uptake of tritiated thymidine autoradiographically, and the frequency of goblet cells in conjunctival epithelial biopsy specimens from nine normal subjects and from 11 patients (seven women and four men ranging in age from 50 to 80 years) with ocular cicatricial pemphigoid. The mitotic rate of patients with the disease was significantly higher than that of normal subjects, 7.2 +/- 2.2 vs 1.6 +/- 0.2 labeled cells per 100 basal epithelial cells (P less than .01). The goblet cell frequency, however, was significantly less in patients than in normal subjects. This suggests that ocular cicatricial pemphigoid is associated with hyperproliferation of the conjunctival epithelium, with a concurrent failure of normal conjunctival differentiation.
