CARDENAS DIAZ, Taimi et al. Risky corneal endothelium in patients with indication of cataract surgery. Rev Cubana Oftalmol [online]. 2013, vol.26, n.2, pp. 198-207. ISSN 0864-2176.

Objective: to identify the risk of edema associated with the morphological and functional parameters of the corneal endothelium in those patients with indication of cataract surgery. Methods: a cross-sectional and descriptive study was performed in 200 eyes from the patients attending the preoperative cataract surgery service. The studied variables were age, sex, risk of edema, pleomorphism and polymegatism. Each patient was examined with the specular microscopy and also a slit-lamp examination was made to look for cornea guttata. Results: the average age of the group was 70.7 years, with females predominating (67.7%) over males (32.3%). There was no risk of edema in 80.5% of cases whereas the risk was present in 19.5% (39 eyes). Polymegatism and age were associated, being this problem present in 176 eyes for 88% of the total number and predominant in its mild staging in all the age groups for 80.5%. Pleomorphism affected 186 eyes (93%) and 103 of them (51.5%) was at the mild staging and 78 (39%) at the moderate staging. Conclusions: reduction in the cell density is not the only parameter indicative of a risky endothelium for a cataract surgery, since others such as polymegatism, pleomorphism and presence of cornea guttata are also important.
