Histopathological changes in the trabecular meshwork in primary congenital glaucoma
Rao AAmerican journal of ophthalmology case reports 2025; 38: 102340
PURPOSE: To evaluate the morphological changes in the ex-vivo trabecular meshwork TM specimens from patients with primary congenital glaucoma. METHODS: Five trabecular meshwork (TM) specimens obtained after microincisional trabeculectomy from 4 patients with primary congenital glaucoma (mean age) were analyzed using and eosin staining. RESULTS: The trabecular meshwork in PCG showed an expansion of the juxtacanalicular and corneoscleral meshwork regions with increased cellularity, thickened TM beams, prominent spindle-shaped nuclei suggesting epithelial mesenchymal transformation predominantly and two morphologically distinct zones of the juxtacanalicular region. CONCLUSIONS: Increased cellularity, zonal expansion and mesenchymal changes in specific TM regions suggest aberrant differentiation and differential dysgenesis of different TM regions in PCG.
