The purpose of this study was to analyse the outcomes and complications observed in a cohort of patients with unilateral superior rectus recession in bilateral asymmetric dissociative vertical deviation (DVD) with strong preferential fixation. This was a retrospective review of 14 patients with mean age at DVD surgery of 8.43 ±2.79 years (five males, nine females). All underwent bilateral medial rectus recession for infantile esotropia. Mean age at first surgery was 26.5 ±3.1 months. There were no surgical complications. Mean manifest DVD in the non-dominant eye measured 17.8 ±2.7PD and in the dominant eye measured 8.8 ±1.2PD preop. DVD surgery involved superior rectus recession of the non-dominant eye with a mean of 7.1 ±0.5mm recession. Postop DVD reduced to 3.1 ±0.8PD with no development of hypotropia, anti-elevation syndrome, diplopia, changed fixation or, importantly, a contralateral DVD. The authors acknowledge this being a retrospective study, small numbers, and short follow-up period.
