Symptoms: The formation of an opaque spot in the lens or pupil of the eye. In young dogs, when it occurs, which is not frequent, the whole pupil seems to be involved at once, but in old dogs it generally commences as a small speck, and gradually increases. The cornea or front of the eye generally remains clear. Of course there is loss of vision of the affected eye to a more or less extent, according to the size and density of the cataract.

Treatment: The following drops improve the sight when the cataract does not affect the whole pupil:—

Recipe:

Sol. Sulphate of Atropine,	10 drops.
Sulphate Zinc,	¼ grain.
Distilled Water to	1 ounce.

Operation, except for improving the appearance of the eye, is useless in the dog, as wearing of spectacles is impracticable.
