Thomas Stevenson at 25. by trade a shoemaker, has a considerable diminution of sight in both eyes, but it is most remarkable in the right. And in that eye in particular, a slight degree of whitness is discoverable at the interior part of the eye in the seat of the crystalline lens. Both pupils still continue to contract pretty freely on the action of light, when first exposed to it. But in ordinary light they appear to be rather more dilated than natural. This diminution of vision prevents him from being able to follow his usual employment as he cannot observe even the white stiches of a shoe, & it likewise prevents him from reading any book as he has consistently the appearance of something flying before his eyes, & if he attempts to persevere for any length of time he totally loses the power of vision. By candle light he cannot distinguish objects, with any degree of accuracy, by either eye.

In every other respect, he is in good health.

The affection of his eyes was first observed about two months ago. He happened to be shipwrecked [about] eight days after being first attacked with it, since that time, it has been much aggravated, growing daily worse. No medicines

He has used no medicines
