PURPOSE: To evaluate the incidence, associated risk factors, graft status and treatment modalities in patients with post-penetrating keratoplasty glaucoma. METHODS: A retrospective analysis of 747 consecutive penetrating keratoplasties was undertaken at a tertiary eye care centre. The frequency of post-penetrating keratoplasty glaucoma was determined and correlated with the pre-operative corneal diagnosis, lens status and associated surgeries performed during penetrating keratoplasty. The response to antiglaucoma therapy (i.e. medical, surgical or cyclo-destructive procedures) and graft outcome was also evaluated. RESULTS: The incidence of post-penetrating keratoplasty glaucoma was 10.6% (79/747). Pre-operative corneal diagnosis of adherent leucomas was significantly associated with the development of postoperative glaucoma. Post-penetrating keratoplasty glaucoma was significantly higher in aphakes (odds ratio (OR) 6.6; confidence interval (CI) 3.81-11.69) compared with phakic or pseudophakic eyes. Associated vitrectomy (OR 2.32; CI 1.16-4.73) and anterior segment reconstruction (OR 3.31; CI 1.43-7.72) were other high-risk factors. Most patients responded to medical therapy (41/79; 51.9%), whereas filtering surgery and cyclo-destructive procedures were performed in 29.1 (23/79) and 19% (15/79) of eyes, respectively. Despite clear grafts in 39 eyes (49.4%), visual acuity of 6/18 or better was achieved in 15 eyes (18.9%). CONCLUSIONS: A high incidence of post-penetrating keratoplasty glaucoma occurs in eyes with adherent leucomas. Anterior vitrectomy and associated surgeries further accentuate the risk Anti-glaucoma therapy may not achieve optimum visual outcome, despite a clear graft.
