Abstract

Glaucoma is a leading cause of irreversible blindness and accurate monitoring using intraocular pressure (IOP), central corneal thickness (CCT) and visual field analysis is essential for early detection of progression. This 24-month longitudinal analytical study evaluated the prognostic value of Goldmann applanation tonometry, pachymetry and automated perimetry in patients with primary open-angle, primary angle-closure and secondary glaucomas. Mean IOP was high in PACG and secondary angle-closure glaucoma, while CCT was greatest in secondary open-angle glaucoma and PACG and visual field loss was severe in POAG. Adjusting IOP for CCT yielded consistently lower corrected values, emphasizing the importance of pachymetry in refining glaucoma assessment and prognosis. Thus, data support a personalized, multimodal approach to glaucoma monitoring integrating IOP, CCT and visual field parameters to optimize long-term visual outcomes.
