A new microsurgical technique to correct retinal detachment.

Area of Science:

• Ophthalmology
• Surgical Techniques
• Retinal Diseases

Background:

• Retinal detachment (RD) is a serious condition requiring prompt surgical intervention.
• Conventional surgical methods for RD include binocular indirect ophthalmoscopy.
• Evaluating novel techniques is crucial for improving surgical outcomes and patient recovery.

Purpose of the Study:

• To assess the efficacy and outcomes of a new microsurgical technique for repairing rhegmatogenous retinal detachments (RD).
• To compare the results of microsurgical RD repair with those obtained using traditional binocular indirect ophthalmoscopy.

Main Methods:

• A prospective study included 36 patients with rhegmatogenous RD (proliferative vitreoretinopathy grade C1 or less).
• Sutures for buckling/encircling bands were preplaced using a three-mirror contact lens under surgical microscopy.
• Procedures included subretinal fluid drainage, cryotherapy, buckling, break localization, and intravitreal gas injection, all performed under microscopy.

Main Results:

• Excellent intraoperative visualization of fundus details and sclera was achieved in all cases.
• Retinal reattachment was successful in 86% of eyes during primary surgery, with a total success rate of 94% after secondary surgery.
• Visual acuity outcomes were comparable to those of surgery performed under indirect ophthalmoscopy, with 41.7% achieving visual acuity of 0.5 or greater.

Conclusions:

• The described microsurgical technique for RD repair is simple, convenient, and reliable.
• The procedure provides an upright image, facilitating better surgical control and visualization.
• Outcomes, including visual recovery, are similar to conventional RD surgery, suggesting its viability as an alternative approach.
