CAP. XLVIII. De Corneae & Adnatae Ulceribus.
ULcera corneae & adnatae tunicae, Ulcers of the Ho•n•• and Adnata tunicle, are wont to a∣rise from sharp corroding humours flowing in∣to the eyes; and sometimes they follow the Phlyctaenae, or little swellings which breed in the Cornea, but not till they break. There are di∣vers sorts of these Ulcers mentioned in Au∣thors:
〈 in non-Latin alphabet 〉, or Fossula, is a hollow, na•rrow, and hard Ulcer, without filthy matter.
Page 108〈 in non-Latin alphabet 〉, is broader, but not so deep.
〈 in non-Latin alphabet 〉, or Ulcus Coronale, is a round Ulcer in the white of the eye, neer unto the circle na∣med Iris, or the rainbow; it is white, neer to the apple of the eye, and red in the membrane con∣junctiva.
〈 in non-Latin alphabet 〉 is a deep, filthy, and crustie Ulcer.
The Ulcers of the eyes are dangerous, and hard to be cured, but more in the Cornea, than in the Adnata; an Ulcer in the Pupilla is more dan∣gerous, because, after it is cured, it will leave a scar, which will hinder the perspicuity of the Cornea, and so the sight will be hurt.
The following Collyrium doth moderately dry and cleanse: ℞ Aquar. verbenae, & planta∣ginis, ana, ℥ ii. sacchari candi, ℥ ss. misce pro Col∣lyrio; vel ℞ Aquae mellis in B. M. Destillatae, & aquae rosarum, ana, partes aequales.
