To determine the effect of (1) the duration of macula-off rhegmatogenous retinal detachment (RRD) and (2) the preoperative distance between the macula and retinal pigment epithelium (height) on the recovery of visual function.
Patients with a primary macula-off RRD of 24 hours to 6 weeks duration (n = 46) were prospectively included. The height of macula-off detachment was determined using ultrasonography. At 12 months postoperatively, best corrected visual acuity (BCVA), contrast acuity, color confusion indexes (CCI) were obtained. Forward stepwise regression analysis was performed.
Median duration of macular detachment was 7 days (range 2 - 32), and mean height was 1.31 mm. ± SD 1.14. Recovery of visual function was, mean LogMAR BCVA 0.30 ±SD 0.31, median LogMAR contrast sensitivity 1.5 (range 0.15-1.70), median CCI saturé 1.13 (range 1.00 - 2.66) and median CCI desaturé 1.76 (range 1.00 - 3.20). A shorter duration of macular detachment was correlated with a better visual recovery, CCI saturé (p < 0.005), LogMAR BCVA (p = 0.011). Also, reduced height was correlated with a better visual recovery, LogMAR BCVA (p = 0.018), and LogMAR contrast acuity (p = 0.021)). Subgroup analysis of patients with macular detachment of ≤7days (n=25), showed that reduced height was correlated with better recovery of contrast acuity (p = 0.024). In this subgroup, duration was not correlated with better visual recovery (p > 0.05). In patients with macular detachment of more than 7 days (n=21), reduced height was correlated with better recovery of LogMAR BCVA (p = 0.006), and LogMAR contrast acuity (p = 0.004)). In this subgroup, duration was correlated with recovery of color vision (CCI desaturé (p = 0.049), and CCI saturé (p < 0.005)).
In macula-off RRD patients, an increase in the duration or the height of macular detachment are associated with a worse recovery of visual function (visual acuity and contrast acuity). Recovery of color vision is worse in case of a longer duration (>7days) of macular detachment.
