Introduction Purpose The present study is a 20-year retrospective study of 2.343 corneal transplants performed in patients from Northeast at HOPE ( Hospital de Olhos de Pernambuco) and FAV (Fundação Altino Ventura). Demographic profile (gender, residency and age), leading causes and indications, visual acuity results, re-graft rates and post-operative visits are reported.

Demographic Profile of Corneal Transplantation patients over the past 20 years at a Northeast Brazil Eye Hospital Cecilia M Cavalcanti , Ventura R, Cavalcanti BM, Cavalcanti RF Material and Methods Aretrospective study was done. Data was obteined from patients chart, demographic profile, leading causes (bullous keratoplasty, keratoconus, leucoma and others - trauma, corneal perforation, corneal meelting, keratoglobus, failure and corneal ulcer). Visual acuity was reported as presenting visual acuity and re-graft rates were recorded. Post-operative visits were considered as eye examinations at the corneal department (were excluded the emergency visits or eye complementary examination).

Demographic Profile of Corneal Transplantation patients over the past 20 years at a Northeast Brazil Eye Hospital Cecilia M Cavalcanti , Ventura R, Cavalcanti BM, Cavalcanti RF Results Gender: males 54% and females 46%. Average age: 50,3 years. Residency: urban 63% and rural area 37%. State procedence: Pernambuco 96 % and other States 4%. 29% 41% 12% 18% Others cause include: trauma, ulcer, corneal perforation, keratoglobus and graft failure

7. Demographic Profile of Corneal Transplantation patients over the past 20 years at a Northeast Brazil Eye Hospital Cecilia M Cavalcanti , Ventura R, Cavalcanti BM, Cavalcanti RF Discussion The long-term outcome for the optical indications showed a trend to endotelium related problems over the time line groups. This related factor is similar to other studies, as the Asian Eyes study and the West study. This could be explained by the phacoemulsification surgeries. Tectonic transplants for corneal infections and perforation are a significant percentage of corneal transplantation. However, the re-graft rates are higher than in optical treatments. The poor prognosis in terms of graft survival in tectonic corneal transplants can be explained by the severity of the indications and in some cases the delay in treatments.

Demographic Profile of Corneal Transplantation patients over the past 20 years at a Northeast Brazil Eye Hospital Cecilia M Cavalcanti , Ventura R, Cavalcanti BM, Cavalcanti RF Discussion Keratoconus indications have been decreasing over the years, possibily due to new treatment options as: newer contact lenses, intra-estromal rings and crosslinking therapy. Re-grafts rates showed a 17%. However it is important to remember that many corneal transplants that fail do not go for re-graft, so the graft survival rates are lower than 83%. Some studies showed a 50% of graft failure over ten years.
