Nimesha is also called as Nimisha.
Nimesha, definition, meaning, pathogenesis
Nimisha is an eye disorder and occurs in the eyelids. In this condition, the nimeshini siras i.e. the nerves responsible for closure of eyes, located in the eyelids are afflicted by vitiated vata. Consequently, the vitiated vata causes excessive movements in the eyelids. This can be understood in terms of the eyelids become weak leading to repeated flapping or winking of eyes. This condition is called nimesha eye disorder in which the phenomenon / function of normal closure of the eye is afflicted to a greater extent.

The pathogenesis of nimesha disorder will occur when these nerves are afflicted by the vitiated vata. ‘The vitiated vata, on getting lodged in the nimeshini siras located in the eyelids will cause excessive movements in the eyelids. This is called nimesha eye disorder’.

Explanation of Nimesha eye disorder by master Videha
Master Videha too has explained the nimesha disorder in the same way as Sushruta but he has mentioned the name of the nerve as ‘unmeshini’ instead of ‘nimeshini’. He has also mentioned that this disorder cannot be treated i.e. nimisha eye disorder is incurable.
According to master Vagbhata – ‘Nimesha is an eye disorder in which the eyelids afflicted by vitiated vata cause closure and opening of the eyelids frequently and there is absence of pain in the eyelids’. Sarvangasundari commentary of Ashtanga Hridaya too explains the condition in same terms as that of Vagbhata.

Nimesha eye disorder can be compared to the ‘affliction of the third cranial nerve supplying the Levator Palpabrae muscle’. This eye condition can also occur due to the affections of the 7th cranial nerve.
A muscle named Levator palpebral superioris helps in lifting the eyelid, i.e. in opening the lid. Another muscle orbicularis palpabrum enables the lid to drop down and close. These both muscles are related with the opening and closure of the eyelids i.e. movements of the eyelids.
Read – Anatomy of Eye: Netra Rachana: Ayurveda Perspective
The third cranial nerve i.e. Oculomotor nerve supplies the upper eyelid muscle i.e. levator palpebrae superioris. The branches of the seventh cranial nerve i.e. facial nerve supply orbicularis palpabrum / orbicularis oculi muscle. These two nerves and their branches control the eye movements / eyelid movements via their supply to these eye muscles. Affections of these nerves lead to weakness of the muscles controlling the closure and opening of the eyelids and would manifest with symptoms resembling those of nimesha eye disorder.
Treatment of Nimesha eye disorder
As already said, Nimesha eye disorder is incurable condition. Therefore no medicinal or surgical treatments have been mentioned for the treatment of Nimisha eye disorder in the Ayurvedic treatises.
