Abstract
Corneal endothelial cell density was determined in 64 eyes (32 patients) with pigmentary glaucoma and in 18 eyes (9 persons) with pigment dispersion syndrome without glaucoma. Twenty-eight healthy eyes served as controls. The glaucomas were stabilized with topical treatment or following laser trabeculoplasty or filtration surgery. The mean duration of the glaucoma was 7.6 years (SD 6.1 years) subsequent to diagnosis. Neither in the glaucomatous, nor in the pigment dispersion syndrome eyes, could any statistically significant difference in cell density be noted compared to the control series. Within the glaucoma group pressure level, topical treatment, laser trabeculoplasty and trabeculectomy did not have any statistically significant effect on cell counts. Distinct pleomorphism and polymegatism of the endothelial cells were observed in the study groups. The endothelial cell density decreased linearly with age.
