Glaucoma is an increase in pressure within the eyeball. At first the eye appears very red with a dilated pupil, then the eye becomes larger in size and the cornea looks blue or cloudy. This condition requires immediate attention and is considered a medical emergency. Medical and/or surgical attention is needed to save the sight and the eye itself. Many times the affected eye is already blind by the time the owner has recognized the condition. We use a cryotherapy (freezing) procedure and diuretics to reduce the intraocular pressure.
