ENO1 and cancer-associated retinopathy: In our study of non-paraneoplastic retinopathy cases, the most common ARA type was the anti-carbonic anhydrase II (anti-30 kDa), whereas a predominance of anti-recoverin (anti-23 kDa) or anti-alpha-enolase (anti-46 kDa) antibodies would have been expected if the cohort contained primarily paraneoplastic cases.
