Clinical Investigation



To report 4 cases undergoing 25-gauge endoscopic vitrectomy for the treatment of proliferative vitreoretinopathy with severe corneal opacity in which a transpupillary view of the fundus was not possible.

Study Design

A retrospective interventional case series.


The main outcomes measured were postoperative anatomic status of the retina and subjective improvement of vision. Results: Postoperative reattachment of the retina and subjective improvement of vision were achieved in all 4 eyes.


Twenty five-gauge endoscopic vitrectomy provides a clear view making it possible conduct pars plana vitrectomy in order to reattach the retina in cases of proliferative vitreoretinopathy with severe corneal opacity.

Supplementary material

Supplemental video Intraoperative view of patient #2 with a 25-gauge endoscope. Endoscopy revealed proliferative vitreoretinopathy with closed funnel without view of the optic disc, which is consistent with preoperative findings of B-scan ultrasound. Microforceps were used to grasp the proliferative membrane over the funnel and then pull by substituting the optic disc, ora serrata, and PFCL with the 2nd forceps in order to stabilize the detached retina. Endolaser was applied under PFCL. The original tiny retinal break at 6:00 portion of periphery was identified. After removing PFCL, fluid/air exchange and internal drainage of residual subretinal fluid through the intentional retinotomy site was subsequently performed. Then silicone oil was injected, followed by confirming the reattachment of the retina with an endoscope. (WMV 34585 kb)
