Aberration of the sense of sight, which transmits the image of imaginary objects. This affection sometimes depends on a slight opacity in the transparent parts of the eye; the cornea, crystalline, or vitreous humour, when it is symptomatic and of no consequence. At other times, it appears to be idiopathic; and occurs particularly in those who have been in the habit of constantly fixing their eyes on very brilliant or small bodies. The objects fancied to be seen are various. They are sometimes circular, perpetually moving; or shining, or black spots, cobwebs, insects, or pieces of wool. These appearances sometimes continue for a few days; being depended on the state of the nerves of the individual at the time; or they may exist for life, and ultimately impair the sight. Certain of them change their position, and apper to be seated in the humours of the eye, and- it has been supposed- in vitreous humour more especially. If the affection be symptomatic, it is of but little moment. If idiopathic, and connected with any excitement of the brain, which is not often the case, attention of the brain, which is not often the case, attention will have to be paid to that organ.
