PURPOSE: To compare corneal sensitivity between normal eyes and those whith phthisis bulbi and also to analyze the alterations of corneal sensitivity in phthisis bulbi induced by wearing ocular prosthesis. METHODS: Prospective study of 23 patients with unilateral phthisis bulbi. Bilateral cornea sensitivity was evaluated using the Cochet-Bonnet esthesiometer before and after 3 months of wearing ocular prosthesis. RESULTS: In all patients, corneal sensitivity of the eye with phthisis bulbi was lower than that of the normal eye (control). In 96% there was decrease of corneal sensitivity after adaptation of ocular prosthesis. CONCLUSION: After wearing ocular prosthesis, there is a reduction in corneal sensitivity in phthisis bulbi. The pathophysiology seems to be the same as that found in contact lens wearers.
