Drainage of Subretinal Fluid
Two techniques for drainage of subretinal fluid are described and compared: (1) externally observed drainage through an ‘L’ shaped sclerotomy with a sharp wire needle; and (2) ophthalmoscopically observed (internal) drainage through a limbus parallel sclerotomy with Wilder picks. Complications encountered are similar and minimal. Drainage under ophthalmoscopic control is utilized in cases with shifting fluid, shallow detachments, choroidal plus retinal detachments, thickened choroids, and following failure to obtain fluid with the external observation technique.
