Indicações de ceratoplastia penetrante em Pernambuco

Abstract

There were no significant differences between the frequencies of the leading indications during the period of study. On the other hand, the frequencies of those indications were different from those of other centers. It should be stressed that Pernambuco and Amazonas states show greater frequencies of ulcerative conditions, not similar to other centers. This fact is associated with poverty in these states.

Indicações de ceratoplastia: estudo retrospectivo em um Hospital Universitário

“…There was no statistical correlation between sex and the indication for corneal transplantation (p=0.250, ñ=0.116). This is in agreement with other Brazilian studies that also found a predominance of males, with 51.28% (4) , 53% (5) , 59.6% (6) , and 55.6% (7) . However, other studies found a predominance of females, with 52.7% (8) and 53.2% (9) .…”

“…The indications for retransplantation were: irregular astigmatism in 7 (46.6%) eyes, post-refractive surgery in 2 (13.3%), rejection in 4 (26.6%), endothelial failure after transplantation in 1 (6.6%), and post-phakectomy in 1 (6.6%). Other studies found varying rates of retransplantation, some of them similar to our study: 10.1% (4) , 9.8% (5) 13.5% (7) , 12.8% (9) , and 11% (14) . Thanks to improved preservation of corneas, new immunosuppressive drugs, and modifications in surgical techniques, there are now improved prospects for the management of corneal retransplantation.…”

“…Improved intraocular lenses, better cataract extraction techniques, a lower mean age of transplanted corneas, and increased use of viscoelastic to protect the corneal endothelium can help reduce the incidence of the condition. Recent Brazilian studies found higher rates of bullous keratopathy as an indication for transplantation: 19.9% (5) , 21% (6) , 16.1% (7) and 14.7% (9) .…”

“…Surgery is required to cure a bacterial infection in 3-6% of cases (19) . However, significant variations exist for this indication depending on the region and socio-economic conditions, with studies reporting the following results: 17.7% (4) , 21.3% (5) , and 34.9% (7) . In children this can be the most frequent indication (4) .…”

“…Moreover, even with penetrating keratoplasty the infection can recur in up to 15% of cases. The rate of transplant rejection is also high, ranging from 14.6 to 52.0% (40)(41)(42)(43) . In our study, two patients with bacterial keratitis required additional surgery, however the infectious process was cured and conjunctival flap surgery was conducted only to close a persistent epithelial defect.…”
