To find the prevalence of epiretinal membrane in patients with rhegmatogenous retinal detachment after vitrectomy using spectral domain optical coherence tomography and identify associated factors.
A descriptive, transversal and observational study was undertaken in patients after vitrectomy was performed following rhegmatogenous retinal detachment in absence of surgery or trauma whit at least 6 months of follow up since the surgery. Visual acuity was registered before and after surgery. SD-OCT of the macula was taken after surgery.
A total of 66 patients were included, 28 male (42%) and 38 female (58%). There was not any relationship between age/RRD extension and ERM appearance (p=0.4 and p=0.4 respectively). There is a relation in the time of RRD and the moment of surgery in the occurrence of ERM. The longer the postsurgical follow up period, the more likely an ERM is to appear. There was an association between worse visual acuity and ERM appearance. <br />
The prevalence of ERM detected by SD-OCT was 62%, greater as previously reported. ERM may be a cause worst visual acuity in patients with RRD after successful vitrectomy interventions. Gas tamponade type was not influential in the development of ERM. SD-OCT is a useful tool in the diagnosis of ERM in patients after vitrectomy.
