    is more or less inflamed; the lashes are few in numher, stunted in growth, and unnaturally directed either obliquely outwards or towards the globe, and then greatly add to the inconveni- ence and distress of the patient. Lastly, in very bad cases, the ulcerations are extensive and deep, and by their cicatriza- tion lead to the closure of the orifices of the Meibomian ducts, and to the obliteration of the glands themselves. Such was the state of the woman from whom fig. 1 was sketched, and in this condition the eye may long remain, now somewhat better, now worse, but always producing more or less inconvenience and discomfort, if not actual distress, and giving the patient an imsightly and dirty appearance. In children, especially in those of strumous or otherwise unhealthy constitution, or in those who, restless and impatient, are constantly rubbing the lids to relieve the itching, a high degree of inflammation may be set up, and the skin of the lids may be much swollen, hot, and painful, with sometimes a papular and sometimes an eczematous affection on its sm-face. When the disease has been once established, and the patient is exposed to any cause which tends to perpetuate it, as in the case of railway guards and drivers, who are constantly exposed to powerful draughts of cold air, an inflamed con- dition of the lids, attended with more or less thickening and induration, and the frequent formation of small pustules, is persistent—a condition that is termed tylosis. Dr Mackenzie^ remarks that the more important conse- quences of ophthalmia tarsi are tylosis; excoriation of the edges of the lids; obliteration of the Meibomian follicles; madarosis, or loss of the eyelashes; lagophthalmos and ec- tropion, from the contracted state of the sldn consequent upon the healing up of the excoriated lids; trichiasis, or inversion of the lashes; distichiasis, or misplaced eyelashes; and entropion, from repeated ulceration of the edges of the ' On the Diseases of the Eye, 4th edition, p. 148. 1854.
