Outcome of vitreoretinal surgery for rhegmatogenous retinal detachment in X-linked juvenile retinoschisis.

PURPOSE

Rhegmatogenous retinal detachment (RRD) is a vision-threatening complication of X-linked juvenile retinoschisis (XLRS). The aim of this study is to report the anatomical and functional outcomes of vitreoretinal surgery for the treatment of RRD in X-linked juvenile retinoschisis (XLRS).

METHODS

This is a retrospective, interventional, consecutive case series in which case records of 34 eyes of 28 XLRS patients, who underwent surgery for RRD, were reviewed. Statistical analysis used is as follows: visual outcomes were categorized into three groups: improved, remained stable or deteriorated. Wilcoxon signed-rank test was used to determine the difference in visual acuity at baseline and at final visit. Univariate binary logistic regression analysis was used to determine the risk factors for retinal detachment. Any P value < 0.05 was considered as statistical significant.

RESULTS

Mean age of the boys at presentation was 9.2 ± 3.5 years. Indication for surgery was RRD in all eyes. Concurrent vitreous haemorrhage was present in four eyes (11.8%). The primary surgical intervention was scleral buckle in 12 eyes and pars plana vitrectomy in 22 eyes. Persistence of subretinal fluid/redetachment was seen in 15 eyes of which 11 eyes underwent additional surgeries. At final follow up, 27 eyes (79.4%) were noted to have an attached retina. Of the total eyes, in 20, 6 and 8 eyes the visual acuity improved, stabilized and deteriorated, respectively.

CONCLUSION

Favourable outcomes are seen in a majority of eyes after vitreoretinal surgery for RRD in XLRS; however, multiple surgical interventions may be necessary.
