To investigate associations between socioeconomic status, retinal detachment type and post-operative visual outcomes in southern New Zealand. A retrospective review of all cases of rhegmatogenous retinal detachments in Dunedin Hospital over two years was performed. Patient demographics and macula involvement at presentation were the primary outcome measures. The New Zealand Deprivation Index was used to group patients into low (30% least deprived), medium (middle 40%) and high (30% most deprived). Patients were excluded if they were not from New Zealand, or had traumatic detachments. During the study period, 95 retinal detachments in 94 patients were managed in Dunedin Hospital. Only 15% of retinal detachments occurred in the most deprived. More deprived patients had longer delays before assessment in hospital (mean of 29.8 days versus 10.1 days for the least deprived and 12.8 days for the medium category, overall p=0.025). There was no evidence of an association between deprivation and macula-off status (overall p=0.650) or visual acuity at one or three months (p=0.063 and p=0.328 respectively). Nor was there an association between referral pathway and macula-off status (p=0.242). Retinal detachment in southern New Zealand may be less common amongst those with the most deprived socioeconomic status who also experience longer delays till first treatment; but there was no association between socioeconomic status and patients being macula-off at presentation, or having poorer visual outcomes. More targeted patient education towards our most deprived citizens may reduce delays in treatment, and result in better visual outcomes.
