Glaucoma after Penetrating Keratoplasty: Incidence, Risk Factors, and Management

Table 4

Odds ratio and 95% confidence interval from binomial regression of the likelihood of developing post-keratoplasty glaucoma (PKG) (versus without PKG) on indications for penetrating keratoplasty (PK), the lens status, and previous high intraocular pressure (PHIOP).
