GALINDO REYMOND, Kenia et al. Open angle glaucoma after pars plana vitrectomy. Rev Cubana Oftalmol [online]. 2016, vol.29, n.2, pp. 308-315. ISSN 1561-3070.

Scientific evidence related with occurrence of the open angle glaucoma after pars plana vitrectomy surgery were reviewed. For the purpose of the documentary research, the articles about this topic indexed in Pubmed-PubmedCentral-Scielo databases were revised, using the subject headings "open angle glaucoma" and "pars plana vitrectomy". The advanced search used Boolean AND and time restriction between 2004 and 2014. Of 38 identified articles, 16 had to be discarded since they could not be fully accessed. Data were processed through the direct contents analysis. The pathological mechanisms that cause open angle glaucoma after pars plana vitrectomy are numerous and complex. The hypothesis about the oxidative stress damage in the trabecular mesh cells and its effect in the discharge of aqueous humor has a scientific foundation in its pathogeny that makes it plausible. The treatment to manage the ocular hypertension in these patients after vitrectomy is customized; it may go from medical treatment to the use of simple or complex surgical techniques in some cases. The physiopathological mechanisms of the open angle glaucoma after pars plana vitrectomy have not been clarified yet, so new research on the topic is needed.  This paper was aimed at reviewing the scientific evidence linked to the occurrence of open angle glaucoma after pars plana vitrectomy.
