Active inflam- mation in the lens or the surrounding parts, (from wounds, injuries or other diseases) generally leaves inflammatory products or deposits iu tho substance of the lens or its cap- sule, which form permanent opacities. Strokes on the head that produce sudden concussion are said to cause opacities in the lens. There are many cases of cataract, the cause of which cannot be determined; but the most prolific cause of cataract in the horse is periodic opthalmia (moon blindness). Straining the eyes to see objects iu imperfectly lighted barns or stalls, no doubt, plays an important part in producing cat- aracts as well as other eye diseases. Occasionally small spurious cataracts of the capsule dis- appear, because of the great activity of the cells of the cap- sule. But opacity of the lens substance very rarely disap- pear ; because changes in its structure take place very slowly for it contains no blood vessels or nerves. Sometimes small gray specks may remain unchanged; but^ as a rule, the little gray star like opacity gradually increases unil total lenticular or capsular opacity Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Agricultural and Mechanical College
