Combined Laser-surgical Technology of RRD Treatment

Not Applicable

• Conditions: Rhegmatogenous Retinal Detachment
• Interventions: Procedure: Combined laser-surgical technology of RRD treatment

• Registration Number: NCT04403750
• Lead Sponsor: The S.N. Fyodorov Eye Microsurgery State Institution

Brief Summary

Purpose: to assess the efficacy and safety of combined laser-surgical technology of RRD treatment

Detailed Description

The study takes place in the S.N. Fyodorov "Eye Microsurgery" Federal State Institution located in Moscow, Russian Federation.

The study will include 50 patients with rhegmatogenous retinal detachment due to a horseshoe-tear. In addition to the standard ophthalmological examination, all patients will undergo wide-field optical coherence tomography to determine the extension and localization of the vitreoretinal traction zone. The obtained data will be used to planning the 1st step of laser-surgical treatment. All patients will undergo a combined laser-surgical technology, which includes 3 steps: 1) Nd-YAG laser excision of the vitreoretinal traction zone 2) pneumatic retinopexy (10% C3F8) 3) barrier laser photocoagulation around retinal break after retinal attachment.

The patients are going to be followed up for at least 1 year, the main outcome measures are postoperative primary and final anatomic outcome, BCVA and complications.
