Ayurvedic Understanding and Management of Timira in Refractive Pathologies

Refractive Errors (Myopia, Hypermetropia, Astigmatism)

1. Modern Explanation:

Refractive errors occur when light does not focus properly on the retina due to irregular shape of the eye. Types:

• Myopia (Nearsightedness)

• Hypermetropia (Farsightedness)

• Astigmatism (Blurred vision due to irregular cornea)

• Presbyopia (Age-related focus loss)

2. Signs and Symptoms:

• Blurred vision

• Eye strain

• Headaches

• Difficulty in reading or seeing distant objects

4. Doṣa – Duṣya – Samprāpti:

• Doṣa: Predominantly Pitta + Vāta (dries up tears, deranges optic function)

• Duṣya: Rasa, Rakta, Māṃsa, and Majjā Dhātu

• Srotas: Rasavaha, Raktavaha, Majjavaha

• Samprāpti: Vitiated doṣas penetrate into different patalas of the eye, starting from 1st (cornea) to 4th (retina/optic nerve), causing progressive vision loss.

5. Śloka Reference:

सुश्रुत संहिता, उत्तर तन्त्र, 7/18:
"तत्र प्रथमपटलगतं दोषैः संपद्यते तिमिरं नाम..."
“संपतन्ति यदा दोषाः प्रतमा पटलं प्रति।
सञ्जायते तदा तिमिरं तद्रोगः सस्य कथ्यते॥”

🟤 Meaning: When doṣas enter the 1st layer of the eye (patala), Timira begins. If untreated, it progresses to loss of vision (Linganāśa).
