Summary
Subretinal gas is a rare complication following pars plana vitrectomy for retinal detachment. This study details a successful management technique involving external drainage and gas evacuation via retinotomy.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Pars plana vitrectomy is a standard surgical procedure for rhegmatogenous retinal detachment.
- Complications, though rare, require effective management strategies.
Observation:
- Subretinal gas was observed postoperatively in a patient undergoing pars plana vitrectomy for chronic rhegmatogenous retinal detachment.
- The gas was located beneath the retina, hindering proper reattachment.
Findings:
- A novel management technique was employed, involving an infusion line and external sclerotomy to expand the vitreous cavity.
- Residual subretinal gas was successfully removed using fluid-air exchange and a posterior retinotomy.
- This intervention facilitated chorioretinal adhesion and successful retinal reattachment.
Implications:
- This case highlights a rare but manageable complication of pars plana vitrectomy.
- The described technique offers a viable solution for subretinal gas evacuation.
- Effective management ensures favorable outcomes in complex retinal detachment cases.
