Purpose : To present the benefit of preserved sclera for immediately repairing perforated
corneal ulcer and report the clinical outcome of patients undergoing penetrating keratoplasty after
scleral patch graft.
Patients and Method : The results of perforated corneal ulcer patients, who underwent
penetrating keratoplasty after scleral patch graft between January 1996 and December 2002, were
reviewed retrospectively. The causes of the corneal ulcer were also included.
Results : Penetrating keratoplasty was performed after scleral patch graft for perforated
corneal ulcer on four patients, three males and one female. The culture results from corneal scraping
showed
Fusarium spp
in two cases and
Streptococus pneumoniae
in one. One patient had a presumed
bacterial corneal ulcer. The post-penetrating keratoplasty visual acuity ranged from hand motions to 20/
40.
Conclusion : The scleral patch graft procedure for perforated corneal ulcer may benefit in
circumstances of unavailable corneal donors. The results of penetrating keratoplasty after scleral patch
graft were favorable.
