Transretinal puncture with a 41G cannula for posterior residual subretinal fluid in fovea-off retinal detachments treated by vitrectomy VS fluid tolerance VS other conventional drainage techniques: a comparative study

To compare functional and anatomical outcomes between posterior drainage of residual fluid using a 41G cannula, fluid tolerance (R-SRF), and conventional complete drainage methods, including removal through peripheral retinal breaks (PRB), perfluorocarbon liquid (PFCL), and posterior retinotomy (PR).
