RHEGMATOGENOUS RETINAL DETACHMENT AFTER INJECTION OF TISSUE PLASMINOGEN ACTIVATOR AND GAS FOR SUBMACULAR HEMORRHAGE SECONDARY TO AGE-RELATED MACULAR DEGENERATION

PURPOSE

The purpose of this study was to describe the rate, clinical characteristics, and outcomes of rhegmatogenous retinal detachment (RRD) after injection of tissue plasminogen activator (TPA) and gas for submacular hemorrhage displacement.

METHODS

Retrospective analysis of consecutive cases developing RRD after TPA injection and gas for submacular hemorrhage displacement. The rate of RRD was calculated, and a description of RRD clinical characteristics was performed. Anatomic and visual outcomes after RRD repair were analyzed.

RESULTS

Ninety eyes of 90 patients were analyzed. Tissue plasminogen activator was given intravitreally in 53 eyes (59%) and subretinally in 37 eyes (41%). RRD occurred in 6 of 90 eyes (7%). Of these, one had intravitreal TPA and five had vitrectomy with subretinal TPA ( P = 0.04). The mean age was 75 (64-93) years. The median time of RRD occurrence was 42 (1-134) days. All cases had macular involvement. Two cases had PVR at presentation. Vitrectomy was performed in all cases and silicone oil used in five, all of which resulted in permanent silicone oil retention. One case (17%) achieved primary single surgery success. The median final visual acuity was 1.8 logMAR (20/1,260 Snellen).

CONCLUSION

The RRD rate after submacular hemorrhage displacement was 7% in our case series. Rhegmatogenous retinal detachment occurred more commonly after vitrectomy with subretinal TPA injection. The visual and anatomic outcomes were poor, with a high rate of retained silicone oil and recurrent RRD.
