Periphery to center dissection for stage V retinopathy of prematurity aided by temporary iris retractors - a pilot study

Abstract

Aim: To discuss the results of a pilot study involving the management of stage V retinopathy of prematurity using the technique of 'periphery to center enblock dissection', aided by temporary iris retractors and bimanual surgery.

Materials and methods: Six eyes of 5 patients with stage V retinopathy of prematurity underwent closed lensectomy and vitrectomy procedures. Temporary iris retractors were used  to permit exposure of  the periphery. Bimanual dissection of the fibrovascular tissue was done from the periphery to center under viscoelastic substances.

Results: Tissue dissection was very satisfactory with this technique. At last follow up, 2 eyes had total retinal reattachment, 2 eyes had posterior polar reattachment and 2 eyes had persistent total retinal detachment.

Conclusions: 'Periphery to center enblock dissection' is possible in Stage V Retinopathy of prematurity by closed route using bimanual surgery and aided by temporary iris retractors. This technique enables removal of the fibrovascular tissue very satisfactorily.
