वातेन नेत्रेऽभिष्यण्णे नासानाहोऽल्पशोफता । शङ्खाक्षिभ्रूललाटस्य तोदस्फुरणभेदनम् ॥ १ ॥
By (increase of) Vata, the eye becomes moist, there is distension and slight swelling of the nose, pricking, pulsating and splitting pain in the temples, eyes, brows and forehead;
the secretion of the eye is dry (non-sticky) and little in quantity, tears are cold, thin, unsteady pain in the eyes, difficulty in opening and closing the eyelids, feeling as if the insects are crawling in the eyes,
अक्ष्याध्मातमिवाभाति सूक्ष्मैः शल्यैरिवाचितम् । स्निग्धोष्णैश्चोपशमनं सोऽभिष्यन्द उपेक्षितः ॥ ३ ॥
feeling as though eyes are bloated (increased in size) and as though filled with minute foreign bodies, comfort is obtained by the use of unctuous and hot things. This disease is Abhishyanda.
अधिमन्थो भवेत्तत्र कर्णयोर्नदनं भ्रमः । अरण्येव च मथ्यन्ते ललाटाक्षिभ्रुवादयः ॥ ४ ॥
This (Abhishyanda) if neglected leads to Adhimantha; characterized by noise in the ears, giddiness and churning like pain in the forehead, eyes, brows etc.
This also if neglected, leads to Hatadhimantha, in which pain of different kinds develops, there are ulcers on the area of vision and loss of vision also.
