Corona, a seven year old beagle, was examined by Dr. Grant. She presented with a swollen, red engorged right eye. Dr. Grant quickly diagnosed glaucoma after performing the following tests: a flourescein stain, schemer tear test and tonometry checking for intra-ocular pressure.
Glaucoma is an increase in intra-ocular pressure (the pressure of fluid inside of the eye). It is caused by inadequate drainage of aqueous fluid from the eye. It happened due to inherited anatomical abnormalities in the drainage angle or by secondary glaucoma due to disease such as tumor, intra-ocular bleeding or damage to the lens or injury. It is very painful and blindness can occur quickly unless the intra-ocular pressure is reduced. Treatment options vary.
Coronas' owner elected to have the eye removed (eye enucleation) due to the advanced state of her eye. Dr. Grant performed the surgery with no complications and Corona went home on pain medication and continues to do very well. She has no problem leading a normal life with just one eye.
