CHAPTER V.
Now we shall discourse on the chapter which deals with the pathology of the diseases of the black part of the eye—Choroid including the Iris (Krishna-gata-Roga-Vijnániya). 1.
The diseases which are found to invade the region of the Choroid including the Iris (Krishna-mandala) have been briefly said to be four in number. Their names are Sa-vrana-Śukra, A-vrana-Śukra, Pâkátyaya and Ajakâ. 2.
Symptoms:—A puncture-like dip in the region of the (Krishna-mandala) with a sensation there as if the part has been pricked with a needle and attended with an excruciating pain and a hot exudation is called Sa-vrana-Śukra. If the seat of this disease considerably remote from the pupil — entire part of the Drishti (Retina) be marked by the absence of pain and discharge and be not deep-seated and if there be not double spots, it offers very little chance of remedy. 3-4.
Symptoms and Prognosis of A-vrana-Śukra:— A whitish film appearing on the region of the Choroid including the Iris (Krishna) like a speck of transparent cloud in the sky, and attended with lachrymation and slight pain due to the eye-disease known as Abhishyanda (Ophthalmia—lit. secretion) is called the A-vrana-Śukra. This is easily curable. A case of Avrana-Śukra (non-ulcerated film) which is thickened, deep-seated and long-standing, may be cured only with the greatest difficulty, while an long-standing case of this disease, if it is mobile, covered with shreds of flesh, vein-ridden, stretching down to the second layer of skin (in the eye) and obstructing the vision.
