Gas Tamponade for Retinectomy in PVR-Related Retinal Detachments: A Retrospective Study

Area of Science:

• Ophthalmology
• Retinal Surgery
• Vitreoretinal Diseases

Background:

• Proliferative vitreoretinopathy (PVR) presents complex challenges in retinal detachment management.
• Anterior and inferior PVR retinal detachments often require advanced surgical interventions.
• Evaluating novel tamponade agents is crucial for improving surgical outcomes.

Purpose of the Study:

• To assess the anatomical and functional results of retinectomy using perfluoro-octane gas (C3F8) as a tamponade agent.
• To determine the efficacy of this surgical approach in patients with complicated PVR-related retinal detachment.
• To analyze visual acuity, epiretinal membrane formation, and intraocular pressure following the procedure.

Main Methods:

• A cohort of 12 patients with inferior and anterior PVR retinal detachment underwent retinectomy with C3F8 gas tamponade.
• Primary outcome measured was anatomical success; secondary outcomes included visual acuity, ERM presence, and IOP.
• Patients were monitored postoperatively to evaluate surgical outcomes and complications.

Main Results:

• The primary anatomical success rate was 75% at a mean follow-up of 9.8 months.
• Reoperation was necessary in 25% of cases; 33.3% developed postoperative epiretinal membranes.
• Visual acuity improved in 25% of patients, remained stable in 25%, and deteriorated in 16.7%.

Conclusions:

• Retinectomy combined with C3F8 gas tamponade demonstrates a 75% primary success rate for PVR retinal detachment.
• This therapeutic strategy can lead to anatomical and functional restoration in challenging PVR cases.
• Further research may explore optimizing C3F8 use in complex retinal detachments.
