I have gone through this excellent treatise "NETRAROGA VIGNANAM" writ-ten by my learned friends Dr.K.Nishteswar and Dr.R.Vidyanath. It is a pleasure to go through this book. They have brought out an introductory chapter containing the historical review from Vedic literature through Samhitas to Buddha and Jaina literature. It is quite interesting to know that Acharyas given many names as (Paryayavachaka) syn-onyms for eye like Akshi, Netra,Nayanam, Chakshush,Darshanendriya,Nimi, Nimisha, Lochana etc. Though they are synonyms, each one has got a specific meaning incorpo-rated or ingrained into the Shabda.
It is also interesting to know that Gods wanted to make the king Nimi to return to his mortal body, but he requested the Gods to make him the organ of eye in all living beings to see the world forever. It is true that in some of the invertebrates such as insects and crustaceans have optically active spots throughout the body, which are given the name of Ommatida. They are tiny independent photoreceptor units. The authors have done an extreme exercise in balancing the rich ancient knowledge of Samhitas with those principles of modern ophthalmology. They have also mentioned about the bio-chemistry of ageing of lens into cataract.
The classification of eye diseases by Acharya Sushruta in Uttara tantra into seventy six categories is well brought out. The relevance of infection in eye diseases and their treatments not only highlights but also well correlates with abhishyanda, suggesting control of mucous secretion. Bacteria flourish in nutrient media such as mucous. This treatise is considered by me as an important referral source for research workers. A number of herbal drugs and natural products are mentioned for minimizing mucoid expression so that incidence of bacterial infections in specific sites of the uveal tract are reduced.
There is a lot of scope to study into the biochemistry of the organs of uveal tract and the phytotherapy. Triphala containing the berries of three myrobalans provides anti-oxidant effect, cytoprotective effect and protection to beneficial gut bacteria. Thus, you can handle cell damage management through Emblica officinalis, sustainable cell life with Terminalia chebula and through Terminalia bellerica protect symbiotic gut bacteria. Symboitic gut bacteria convert the prebiotics in the food into probiotics and improve the quality of nutrition needed by eye.
An interesting angle has been brought into focus by the authors in constitution-ally basing eye disorders. Constitution based on doshic profiles is highly scientific in that the constitution reflects the biochemical status of a person either in health or dis-ease. This can give us a correct finger printing of a person, which in turn helps us in selecting a suitable line of treatment. The treatment protocol under such conditions naturally involves purva karma through (intra corporeal depuration) panchakarma. This reestablishes a biochemical homeostasis. Then the main treatment through drugs or surgery becomes easier for fast recovery. This is a sort of metabolic management of surgical or therapeutic treatment options. Another interesting treatment modality is the concept of giving medicines through ghritam either in the form of pre-conditioning by ghritapana or by giving ghrita-containing medicines like triphala ghritam etc. Since eye is a neurobiological organ with a specific function of receiving light, the energy requirement is of high order and alochaka pitta sustains it so, ghrita having a phospholipid base provides the necessary energy requirement of the eye. I fondly hope the learned scholars in Ayurveda, P.G students and all graduates will find this book as a very useful and helpful treatise. This treatise will be a good referral for their studies. I congratulate the authors Dr. K. Nishteswar and Dr. R. Vidyanath for their immense efforts in bringing out such a scholarly work.
