GUARACHE, DANIEL ERNESTO; GUARACHE, FERNANDO ELÍAS  e  LEON GUARACHE, FERNANDO. CYSTOID MACULAR EDEMA PREVALENCE IN PATIENTS UNDERGOING CATARACT SURGERY BY PHACOEMULSIFICATION . Saber [online]. 2016, vol.28, n.4, pp.736-743. ISSN 1315-0162.

The objective of the present study was to establish the prevalence of cystoid macular edema (CME), in patients operated by the technique of phacoemulsification with implantation of intraocular lens. Patients were attended in the Ophthalmology Service at the University Hospital of Caracas for a consecutive period of 3 months in the year 2014.  The  variables  studied  were:  corrected  visual  acuity  and  measurement  of  the  foveal  thickness  by  optical coherence  tomography  (OCT),  4  weeks  after  surgery.  The  sample  was  composed  of  50  patients  operated  of cataract by the evaluated technique, and divided according to their corrected visual acuity into four groups: Group I: between 20/20 and 20/40, group II: 20/50 to 20/70, group III: between 80/20 and 20/200 and the Group IV: 20/400 or less. Ninety per cent of the eyes studied were ranked in Group I. Average foveal thickness was 172 ± 13 µm. There were two (4%) patients complicated with rupture of the posterior capsule, one of which showed decrease of corrected visual acuity 20/40 (2%), as well as implantation of the intraocular lens in the ciliary sulcus (2%) and 198 µm foveal thickness; the other patient, with posterior capsule rupture, did not have impact on the visual acuity. On the other hand, the second patient complicated by implantation of the intraocular lens in the ciliary sulcus (2%) did not have impact on visual acuity. The prevalence of CME was 2%. The complications identified  in  the  patient  that  developed  pseudofaquic  CME  were:  posterior  capsular  rupture  during  surgery  of cataract,  and  implant  of  the  intraocular  lens  in  the  ciliary  sulcus.  OCT  demonstrated  to  be  a  non-invasive diagnostic technique, accurate and reliable in the diagnosis of pseudofaquic CME.
