For the past 15 years, Ocular Pharmacology Department of Dr. R. P. Centre has been involved in developing newer drugs for eye, evaluating their intraocular penetration in animals and human and also to study their efficacy in animal models.     The Ocular Pharmacy in this Department is unique of its kind in India as it caters the drug requirements of Dr. R. P. Centre and render free drug service to poor and needy patients. Our Pharmacy manufacturing division has contributed well in bringing out many newer drug formulations for the first time in the world for various ophthalmic pathologies viz. Norfloxacin eye drops 0.3% for bacterial keratitis, Silver Sulphadiazine for ocular keratomycosis, Centbucridine for corneal anaesthesia, etc.

The bio-analytical facility in the department was established especially for drug evaluation in 1983 and many studies have been conducted through it  so far as evidenced from the national and international publications. In 2004, the Department developed an exclusive advanced Bio-analytical laboratory to more extensively support ocular drug research. In ‘Holi 2006’, the department made a landmark investigation about the presence of toxic dyes in the dry color powders (gulals) which gained lot of public interest. Recently, Ocular Pharmacology Department has been recognized as a DST-FIST sponsored department for the provision of High Precision Analytical Instrument for Bio-analytical work (liquid chromatography coupled tandem mass spectroscopy with triple quadrupole LC/MS/MS).

This active dispensing pharmacy extensively supports the research interests of the Ophthalmologist of Dr. R. P. Centre on all their new research initiatives. Apart from Dr. R. P. Centre it supports research in other Departments of AIIMS in preparing extemporaneous formulations. Presently this department is having 5 PhD scholars working for their thesis work in different eye research areas and having number of publications in the peer reviewed journals of international repute.
