Fig. 6. Trichasis due to trachoma in a 51-year-old man with mature cataract (T/E 3 or TT) (see Table 4). The inturned lashes usually occur in adult life many years after the acute inflammation has resolved. The constant corneal abrasion by the lashes and inadequate tears can produce corneal erosions, ulceration, and opacity, which constitute the major pathway to blindness in trachoma. In this case, there is notching of the upper lid due to previous lid surgery; this can produce corneal exposure and further corneal damage.
