Radial Retinotomies with Endodiathermy for Severe Proliferative Vitreoretinopathy: Short-Term Results

الملخص EN

Purpose.

Retinal redetachment of silicone oil-filled eyes continues to be a frustrating condition that typically requires retinectomy.

We proposed radial retinotomy as a potentially less invasive surgery.

Here, we preliminarily explored its feasibility, efficacy, and safety.

Methods.

Totally 9 eyes of 9 consecutive patients were included in a prospective noncomparative trial.

A series of retinotomies were created by endodiathermy in a radial pattern to relax the foreshortened retina.

The eye was refilled with fresh silicone oil.

The treated eyes were examined via visual acuity (VA) tests, tonometry, slit-lamp microscopy, and fundus photography during a 6-month observation period.

Results.

The procedure was completed in an average of 28 minutes from silicone oil removal to fresh silicone oil placement.

Fundus photography demonstrated that 7 of the 9 eyes (78%) exhibited retinal reattachment.

On average, VA was significantly improved within the first 2 weeks ( P = 0.02 ) and remained stable for the following 6 months.

The change in intraocular pressure was not significant ( P = 0.76 ), and no adverse event was observed (0%).

Conclusion.

Radial retinotomies with endodiathermy were shown to be feasible, effective, and safe in selected cases of inferior contracted retina without vitreous base fibrosis over a 6-month observation period.

This trial is registered with NCT02201706.
