Twenty-eight patients with macular oedema received intravitreal treatments and 10 without macular oedema remained untreated. All underwent full-field electroretinography (ERG) within one month of CRVO debut (ERGI) and a follow-up (ERGII). The primary outcome was long-term change in total retinal function. Electrophysiological and clinical results of the groups were compared. Further, the treated eyes were divided into ischemic vs non-ischemic groups and compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean ETDRS letter score improved significantly in the treated group (p\u2009=\u20090.026). Mean central foveal thickness (CFT) decreased significantly from ERGI to ERGII and from ERGI to final visit in both the treated and non-treated groups (p\u2009&lt;\u20090.001, &lt;0.001 and p\u2009&lt;\u20090.002, 0.004, respectively). The ERG results showed significantly decreased a- and b-wave amplitudes of combined rod-cone response from ERGI to ERGII in both groups (p\u2009=\u20090.004, 0.004 and p\u2009=\u20090.037 and 0.037, respectively). The non-ischemic group saw a significant decrease in the same response from ERGI to ERGII (p\u2009=\u20090.008, p\u2009=\u20090.027 respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Long-term visual outcome improved in the treated group and remained unchanged in the untreated group. CFT improved in both groups, but retinal function in both was still reduced 4 years after CRVO diagnosis.
