Summary
A modified external needle technique effectively drains subretinal fluid in rhegmatogenous retinal detachment. This method achieved high retinal reattachment rates and favorable complication profiles, improving visual acuity.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Rhegmatogenous retinal detachment (RRD) is a serious condition requiring prompt surgical intervention.
- Subretinal fluid drainage is a critical step in RRD repair, with various techniques available.
Purpose of the Study:
- To evaluate the efficacy and safety of a modified external needle subretinal fluid drainage technique in patients with RRD.
- To assess surgical outcomes including reattachment rates, complication incidence, and visual acuity.
Main Methods:
- A retrospective study of 187 patients undergoing scleral buckle with modified external needle drainage for RRD.
- Subretinal fluid drainage was achieved by increasing intraocular pressure via scleral buckle tightening and external needle insertion under indirect ophthalmoscopy.
- Key outcomes included drainage success, reattachment rates, complication rates, and visual acuity.
Main Results:
- Successful subretinal fluid drainage in all cases.
- A 91% one-operation retinal reattachment rate and a 98% final reattachment rate.
- Postoperative visual acuity significantly improved from logMAR 1.1 to 0.54 (P < 0.0001).
Conclusions:
- The modified external needle drainage technique is a versatile and effective method for subretinal fluid management in RRD.
- This technique offers comparable or superior reattachment rates and complication profiles to other drainage methods.
