PurposeTo investigate aqueous flare as a preoperative predictor for later proliferative vitreoretinopathy (PVR) development in patients with rhegmatogenous retinal detachment (RD) and to determine the validity of this measurement in patients at low clinical risk for postoperative PVR. MethodsThis study included 100 eyes of 100 patients who underwent surgery for primary RD. Aqueous flare was determined preoperatively with a laser flare-cell meter (Kowa FM-500, Kowa Company Ltd, Tokyo, Japan). Patients were followed for at least 6months postoperatively. Failures related to PVR were recorded for statistical analysis. ResultsTwenty eyes (20%) developed PVR postoperatively. Preoperative flare values in these eyes were significantly higher than in eyes with no redetachment (48.1261.24 versus 17.74 +/- 29.63 photon counts per millisecond (pc/ms), p=0.002). The odds ratio for PVR development with flare values >15pc/ms was 12.3 (p<0.0001, 95% confidence interval, 3.54-42.59). Of 54 eyes at low clinical risk for postoperative PVR, five developed PVR postoperatively. Flare values were significantly higher in these eyes (25.30 +/- 7.10pc/ms) than in eyes with no redetachment (12.44 +/- 10.16pc/ms, p=0.008). Using logistic regression, the odds ratio of PVR redetachment risk increased by the factor 1.078 per 1pc/ms of flare value (95% CI, 1.01-1.15). ConclusionPreoperative aqueous flare is a strong predictive factor for PVR redetachment. The laser flare-cell meter provides a fast and safe tool to accurately identify patients at risk for postoperative PVR, especially when clinical examination did not predict this risk.
