    Clinical and Spectral-Domain Optical Coherence Tomography Findings of Patients with Incomplete Visual Recovery after Anatomically Successful Retinal Detachment Surgery by Miltiadis K. Tsilimbaris, Aikaterini Chalkia, Chrysanthi Tsika, Anastasios Anastasakis, Georgios A. Kontadakis

    Published 2015-01-01
    “…Incomplete visual recovery was strongly correlated with presence of macular pathology (P = 0.002), a detached macula preoperatively (P = 0.02), retinotomy (P = 0.025), and pars plana vitrectomy and use of silicon oil as a tamponade agent (P = 0.009). Also, although there was a strong correlation between ellipsoid zone disruption and incomplete visual recovery, a distinct, more course pathology could be identified in all cases of poor visual recovery related to edema, thickening, or atrophy of the macula. …”
