Purpose
Rhegmatogenous retinal detachment (RD) has diagnostically been divided into macula-OFF or macula-ON. The aim of this study was to describe the demographics and primary outcome of patients with RD following surgery with respect to the macular status, and to determine risk factors for macular involvement.
Methods
This prospective, observational, mono-centric cohort study was conducted at the Jules-Gonin Eye Hospital, from February 2015 until March 2017. The study included 194 eligible patients with primary RD. All patients underwent surgical treatment after baseline clinical examination. The dataset was analyzed using descriptive and analytic statistics.
Results
A total of 52.6% (102/194) of patients presented with macula-OFF RD. Mean age was 63.9 ± 12.0 vs. 59.7 ± 11.2 years in the OFF and ON group, respectively. There were 129 men (66.5%) and 65 (33.5%) women, and there were significantly more right eyes affected [right vs. left eyes 123 (63.4%) vs. 71 (36.6%), p = 0.000]. Significantly more myopes (<−3D) presented with a macula-ON RD (p = 0.04). There were more phakic patients in the cohort (55.7%), and phakic eyes were more likely to present with macula-ON RD (p = 0.01). Multivariate modeling showed that pseudophakic lens status and eyes with axial length less than 25 mm (p = 0.06) are independent predictive factors for macula-OFF RD (p = 0.02), whereas sex and laterality were not risk factors for macular involvement.
Conclusion
Pseudophakic lens status and axial length < 25 mm are independent predictive factors for macula-OFF RD. While pseudophakic lens status is a recognized risk factor for RD, shorter axial length has not been previously identified as a risk factor for the macula-OFF RD.
