Introduction:

The objectives of this article are to review and summarize the updated published data that show the relation between treatment with statins and the incidence and progression of glaucoma. We also aimed to pose a hypothesis to explain the protective effects of statins and its association with glaucoma risk.

Method:

a review of the literature was carried out in the PubMed database considering the MeSH terms "statins, hmg coa" or "hmg coa inhibitors" and "glaucoma" or "open angle glaucoma" or "intraocular pressure". All articles including clinical studies and meta-analysis were selected. Comments, letters to editors, retracted articles and research on animal models were excluded. All the articles were published from 2004. 17 articles were finally selected for review.

Results:

most of the studies showed a protective effect of statins on incidence or progression of open angle glaucoma. Nevertheless, other studies did not find a significant association and even one study found association between statin treatment at high doses and more incidence of glaucoma. Neuroprotective effects of statin and inhibition of Rho-kinase may help explain the described effects.

Conclusions:

The published results are not enough evidence to support statin recommendation as preventive treatment for the incidence or progression of glaucoma.
