Normal intraocular pressure in dogs can ranges from 12 to 25 mmHg (1.6 to 3.3 kPa), and both eyes should be similar in pressure. Gonioscopy is a diagnostic procedure to examine the angle of the anterior chamber. Direct and indirect ophthalmoscopy is necessary to evaluate the retina and particularly the optic nerve.
Glaucoma in dogs is a painful condition caused by high pressure within the eye. Two types of glaucoma can affect our canine companions: primary and secondary. Glaucoma can lead to blindness if it ...

When the sensor is subjected to a change in pressure, the electrical resistance is altered and the tonometer's computer calculates a change in pressure according to the change in resistance. A complete measurement cycle requires about eight seconds of contact time. The device also measures the variation in pressure that occurs with the cardiac ...
Differences in pressure between the two eyes are often clinically significant, and potentially associated with certain types of glaucoma, as well as iritis or retinal detachment. Intraocular pressure may become elevated due to anatomical problems, inflammation of the eye, genetic factors, or as a side-effect from medication. Intraocular ...
Ocular hypertension is the presence of elevated fluid pressure inside the eye (intraocular pressure), usually with no optic nerve damage or visual field loss. [1] [2]For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3]
Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...
