When severely large corneal perforation occurs, penetrating keratoplasty is a treatment of choice alternative to enucleation. A twelve-year-old male Shih Tzu was referred with perforated corneal ulcer secondary to keratoconjunctivitis sicca (KCS). Perforated cornea was directly sutured using 10-0 non-absorbable suture material, and rotational conjunctival flap was performed. However, re-perforation of cornea by wound dehiscence was observed at 1 month after operation. The yellowish lens escaped outside the orbit during corneal re-perforation, the diagnosis was re-perforated corneal ulcer, moderate corneal edema, moderate KCS (STT; 6 mm) and endophthalmitis caused by escaped lens outside orbit. Accordingly, penetrating keratoplasty (PK) and evisceration through corneal recipient site and intrascleral silicone ball prosthesis were carried out as the planned treatment, and resulted in good cosmetic improvement compared to enucliation. However, exposure of silicone ball occurred at the 9 months after the surgery due to the irritation of implant, thus enucleation was performed. In perforated large corneal ulcer with severe intraocular damage, evisceration with silicone ball insertion with PK would be alternative treatment choice to improve the cosmetic appearance.

Purpose: To compare the measurements of the rebound tonometer (RT), Goldmann applanation tonometer (GAT) and noncontact tonometer (NCT) in patients who underwent penetrating keratoplasty (PKP), and to evaluate the reproducibility of the RT measurements. Methods: This study included 19 PKP eyes and 28 normal eyes. We compared the intraocular pressure (IOP) measurements of the GAT and NCT with the RT in both groups using Spearman's correlation analysis and the Wilcoxon signed-rank test. The IOP, as measured with an RT in each group, was assessed with respect to reproducibility using the intraclass correlation coefficient (ICC). Results: In normal eyes, there was no significant difference in the measurements obtained with the RT, GAT, and NCT (p > 0.050). In the patient group, the RT measurements were not significantly different from those of the GAT (p = 0.872), but they were significantly lower than those obtained with the NCT (p = 0.011). However, the RT measurements showed a relatively high correlation with those of the GAT and NCT (r = 0.770 and 0.879, respectively). The ICC of the RT was 0.986 for the PKP eye group and 0.961 for the normal eye group, both of which were highly reproducible. Conclusions: In PKP eyes, the measurements obtained with the RT showed a relatively high correlation with those of the GAT and NCT, and the repeatability of the RT measurements was high and similar to those for normal eyes. The RT can therefore be considered a useful method for measuring the IOP in PKP eyes.
