Abstract:
The authors reviewed 39 consecutive cases of severe ocular trauma that had undergone penetrating keratoplasty plus anterior segment reconstruction and evaluated visual outcome, graft survival, and secondary complications. Postoperatively, 49% of eyes achieved visual acuity of 20/100 or better compared with 10% before surgery, and 72% improved at least 2 Snellen lines. With a mean follow-up of 23 months, 31 (80%) initial keratoplasties remained clear, and all 4 subsequently re-grafted corneas maintained clarity, for an overall keratoplasty success rate of 90%. Elevated intraocular pressure occurred postoperatively in 18 eyes (46%), and, among these, 10 of 13 eyes (77%) had preoperative glaucoma, whereas 8 of 26 (31%) did not (P less than or equal to 0.015). Preoperative anterior synechiae could be anatomically corrected at surgery in 80% of cases (24 of 30 eyes). In 7 cases with persistent synechiae, 6 (86%) were associated with glaucoma (P less than or equal to 0.025). Retinal detachment occurred in one case. Thus, despite major trauma and a high prevalence of glaucoma, both the visual restoration and anatomic reconstruction achieved were satisfactory and without severe complications.
