VEITIA ROVIROSA, Zucell Ana et al. Changes of the corneal endothelium in cataract surgery combined with vitrectomy. Rev Cubana Oftalmol [online]. 2012, vol.25, n.2, pp. 202-211. ISSN 0864-2176.

Objective: to determine the corneal endothelium behavior in the cataract surgery and vitrectomy performed simultaneously. Methods: a prospective, descriptive and observational research was carried out in “Ramón Pando Ferrer” Cuban Institute of Ophthalmology from January to November 2010. The sample was made up of 15 eyes from 15 patients, who had undergone cataract surgery and vitrectomy simultaneously. Results: most of the patients were men aged 53 to 67 years. The main causes to indicate the pars plana vitrectomy were retinal detachment and vitreous hemorrhage. Before and after surgery, the average cellular density showed loss of 634 cells (26,8%). Mild polymegatism forms were not detected before surgery but moderate as well as severe forms were observed after surgery. Pleomorphism behaved similarly to polymegatism. Three complications were observed after surgery: ocular hypertension, toxic syndrome of the anterior segment and the anterior uveitis. Conclusions: the evaluation of the state of the corneal endothelium behavior before surgery helps drawing up a surgical strategy to protect this important corneal layer and to establish a visual prognosis of the patient as well as to evaluate the postsurgical progress.
