May not have symptoms besides slight bulging of the iris, unless the cyst is interfering with the field of vision. The exam will measure the way your eyes focus light, the curvature of your cornea and how well you can read a distance chart to determine if you have astigmatism.įortunately, many treatment options for astigmatism exist.

Because hyphemas often occur due to an injury to the eye, you should seek immediate medical care. In cases of hyphema, you may suffer partial or complete loss of vision temporarily.

The hyphema may extend to all of the iris and pupil (the circular, dark area in the middle of the eye). Known as a "refractive error," astigmatism results in distorted vision, rather than clear. I have seen this in Merle colored dogs but never guinea pigs. Which is kinda cool, however she also has something strange going on with one of her pupils, it is like a piece is missing or didnt develop.

If your cornea isn't perfectly round, however, light cannot hit the cornea properly. When light hits a smooth, round cornea, it's able to be sharply focused and result in clear sight. Your cornea controls the way light enters your eye. The lens is behind the iris and pupil, helping to focus light rays. The cornea is the transparent dome on the surface of the eye, covering your iris and pupil. It's caused by having a misshapen cornea or lens.

If that checks out I would move onto testing for toxoplasmosis (parasite) and bartonella (cat scratch fever). Testing that would normally be recommended for this would be a simple Chemistry panel, complete blood count and testing for FIV and Feline leukemia. Cancer would be low on my list because of his age.
