Using Surgical Microscope for Sclera Buckling and Transscleral Cryopexy : An Alternative Procedure of Treatment for Rhegmatogenous Retinal Detachment

Abstract EN

Purpose.

To observe the long-term effectiveness of scleral buckling and transscleral cryopexy conducted under a surgical microscope in the treatment of uncomplicated rhegmatogenous retinal detachment.

Methods.

This was a retrospective analysis in a total of 227 consecutive patients (244 eyes) with uncomplicated rhegmatogenous retinal detachment (proliferative vitreoretinopathy ≤ C2).

All patients underwent scleral buckling and transscleral cryopexy under a surgical microscope without using a binocular indirect ophthalmoscope or a contact lens.

Results.

After initial surgery, complete retinal reattachment was achieved in 226 eyes (92.6%), and retinal redetachment developed in 18 eyes (7.4%).

The causes of retinal redetachment included presence of new breaks in eight eyes (44%), failure to completely seal the breaks in five eyes (28%), missed retinal breaks in four eyes (22%), and iatrogenic retinal breaks in one eye (6%).

Scleral buckling surgery was performed again in 12 eyes (66%).

Four eyes (22%) developed proliferative vitreoretinopathy and then were treated by vitrectomy.

The sealing of retinal breaks and complete retinal reattachment were achieved in 241 eyes (98.8%).

Conclusion.

Probably because of clear visualization of retinal breaks and being controllable under a surgical microscope, the microsurgery of scleral buckling and transscleral cryopexy for uncomplicated retinal detachment exhibits advisable effectiveness.
