Emerging glaucoma therapeutics

The purpose of this review was to discuss the major recent advances in the field of ophthalmology, particularly as it pertains to glaucoma. We reviewed literature using MEDLINE and PubMed databases with the following search terms: “glaucoma,” “melatonin,” “trabecular outflow pathway,” “adenosine,” “rho kinase,” “norepinephrine,” and “matrix metalloproteinases.” We also reviewed pertinent references from articles found in this search. We looked at various studies concerning the clinical trials of glaucoma therapeutics, and therapeutic potential of putative ocular drug delivery systems in glaucoma. Challenges of assuring safety and efficacy of the newer medicines and techniques are pertinent in this regard. However, more research is needed to better elucidate the mechanism of various investigational drug products and drug delivery devices in glaucoma
