Abstract：
:This study was undertaken to develop a feline model of corticosteroid-induced ocular hypertension. In the first experiment, eight cats were selected whose intraocular pressure (17 +/- 0.4 mmHg) was consistently below the mean baseline intraocular pressure of our colony (24 +/- 0.5) during the preceding 2 months. Unilateral twice or thrice daily topical application of 10 microliters 1% dexamethasone sodium phosphate caused a gradual intraocular pressure increase that became significant (P less than 0.05) within 2-3 weeks. There was no significant change in body weight, but several eyes developed cataracts. Similar results were obtained with treatment of normotensive cat eyes with dexamethasone, or with 1.0% prednisolone acetate (PredForte) twice a day. Topical application of PGF2 alpha-1-isopropyl ester (0.1 or 0.25 microgram PG equivalent) to such steroid-treated eyes yielded significant intraocular pressure reduction and pupillary miosis, similar in magnitude to those exhibited by normal eyes. When dexamethasone treatment was reduced to once daily, after prolonged twice daily treatment, intraocular pressure decreased only slightly within 10 days. When dexamethasone treatment was stopped, intraocular pressure declined to normal levels within 6-7 days. These findings show that adult cat eyes develop steroid-induced ocular hypertension that is maintained and reversible. As opposed to previous findings on rabbits, steroid-induced feline ocular hypertension appears to be a good model for this clinical condition and may be suitable for the testing of potential glaucoma drugs.
