Pars Plana Vitrectomy With External Drainage for Nonexudative Retinal Detachment.

Area of Science:

• Ophthalmology
• Surgical Techniques
• Retinal Diseases

Background:

• Retinal detachment with undetected retinal breaks poses a surgical challenge.
• Pars plana vitrectomy is a standard treatment, but subretinal fluid (SRF) management can be complex.

Purpose of the Study:

• To describe a novel surgical technique for retinal detachment involving undetected retinal breaks.
• To evaluate the efficacy and safety of combining pars plana vitrectomy with external SRF drainage.

Main Methods:

• Retrospective observational study of patients with retinal detachment and undetected breaks.
• Standard three-port 25-gauge pars plana vitrectomy followed by perfluorocarbon liquid injection.
• Trans-scleral 27-gauge needle external drainage of SRF and prophylactic laser treatment.

Main Results:

• Successful SRF drainage achieved in 14 out of 15 patients.
• No intraoperative or postsurgical complications were reported.
• All patients achieved a flat retina with no SRF, and no relapses were observed during follow-up.

Conclusions:

• External SRF drainage combined with pars plana vitrectomy is a safe and effective option for retinal detachment with undetected breaks.
• Advantages include preventing retinal pigment epithelium cell dispersion, achieving a dry retina quickly, and minimizing postoperative retinal folds.
