Dr. Gwynn et al., THE INFLUENCE OF AGE UPON INFLAMMATORY CELL COUNTS AND STRUCTURE OF CONJUNCTIVA IN CHRONIC OPEN-ANGLE GLAUCOMA, Acta ophthalmologica, 71(5), 1993, pp. 691-695
We evaluated the influence of age upon conjunctival structure and numb
er of inflammatory cells by studying perioperative conjunctival biopsi
es from 54 consecutive primary open-angle glaucoma patients undergoing
initial filtering surgery (trabeculectomy alone or combined cataract
extraction and trabeculectomy). All patients had received chronic topi
cal glaucoma therapy for >1 year. We divided the patients into three a
ge groups for analysis: 40-60 (n = 10), 61-74 (n = 28), and >75 (n = 1
6) years. We found no statistical difference (p > 0.05, chi-square) in
cell counts of neutrophils, eosinophils, mast cells, macrophages, fib
roblasts, lymphocytes, plasma cells and goblet cells across the three
age groups. In addition, no statistical differences were observed betw
een age groups in vascular density, epithelial thickness as well as mu
copolysaccharide and collagen composition (p > 0.05, chi square). This
study suggests that conjunctival structure and inflammatory cell coun
ts change little with advancing age in primary open-angle glaucoma pat
ients.
