Intraocular pressure (IOP) was measured by use of Mackay-Marg applanation tonometry in 8 normal, manometrically controlled, enucleated, canine eyes with and without 1 of 2 plano therapeutic soft contact lenses (1 and 2) covering the cornea. Differences were not significant between measurements made without a contact lens and those made through either lens at manometer IOP < 30 mm of Hg. At manometer IOP > or = 30 mm of Hg, use of a contact lens tended to result in a statistically greater (P < 0.05) estimate of IOP than when a lens was not used. This difference, however, achieved only a maximum of 2.6 mm of Hg at the 80 mm of Hg value, and was not regarded as clinically important. Measurements obtained through lens 1 were not significantly different from those obtained through lens 2. The IOP can be accurately estimated in dogs, using the Mackay-Marg tonometer, without removing either type of bandage soft contact lens, thereby avoiding potential disruption of an already compromised cornea.
