The impact of duration on the recurrence of rhegmatogenous retinal detachment: optimal cutoff value
- 60 Downloads
To assess the impact of symptom duration on the recurrence of rhegmatogenous retinal detachment (RRD) and to determine the threshold symptom duration for recurrence.
Patient and methods
In this non-comparative, observational case series, a retrospective evaluation was made of the records of patients with RRD at baseline and during the postoperative follow-up period, in respect of postoperative anatomic outcome, prognostic factors for recurrent retinal detachment and the cutoff value of symptom duration.
Recurrent retinal detachment was detected in 33 (17.8%) of 185 patients following primary retinal detachment surgery. The surgery type in phakic patients and preoperative symptom duration had a significantly high odds ratio for evidence of surgical failure. According to the ROC analysis, the threshold preoperative symptom duration was 20.5 days.
Our results showed that early reattachment surgery is necessary to lower the risk of retinal redetachment. The threshold at which RRD recurrence significantly increases is 20.5 days.
