Astanga Hrudaya
स्नेहाञ्जनं च कर्तव्यं नस्यं च क्षीरसर्पिषा। तथाऽपि पुनराध्माने भेदच्छेदादिकां क्रियाम्॥५७॥ युक्त्या कुर्याद्यथा नातिच्छेदेन स्यान्निमज्जनम्। ५७ १/२।
then eye-salve mixed with fats should be done and nasal drops with milk and ghee. Even after these therapies, if it gets swollen, filled with fluid, then pricking or excision should be undertaken, as much as justified, since excess of treatment (pricking and excision) leads to sinking (blindness).
