Characteristics, socioeconomic status and ethnic variations of primary idiopathic macular hole repair in vitreoretinal centers in the United Kingdom
Abstract
OBJECTIVE: The purpose of this multicentre retrospective study was to investigate the characteristics and role of ethnicity and socioeconomic status amongst patients with idiopathic macular holes (IMH) and the surgical outcome.
SUBJECTS AND METHOD: Consecutive patients undergoing primary IMH surgery at three vitreoretinal units in the UK (King's College Hospital, London, UK, Western Eye Hospital, London, UK, Sunderland Eye Infirmary, Sunderland, UK) between January 2007 and May 2017 were included. The main outcome measure was anatomical closure of IMH.
RESULTS: Two hundred and thirty three primary IMH surgeries were included. All patients underwent pars plana vitrectomy, internal limiting membrane peeling, and gas tamponade. 69.10% of patients were European Caucasian, 6.44% were Asian, and 24.46% were Afro-Caribbean. The mean base macular hole diameter (BD) was 475.5mcm. Mean BD was 432.2mcm in European Caucasian patients, 481.3mcm in Asians (P=0.005), and 505.61mcm in Afro-Caribbeans (P=0.006). Regression analysis demonstrated that BD and Afro-Caribbean ethnicity were independent significant risk factors for surgical failure. Those who have longer duration of symptoms (Afro-Caribbeans) and leave in more deprived places (Afro-Caribbeans) in England where found to have lower success rate on macular hole closure.
CONCLUSION: Asian and Afro-Caribbean patients present with larger IMH than European Caucasians. In addition to IMH base diameter, black origin and lower socioeconomic…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
