Long-term outcomes of pars plana Ahmed valve implant and vitrectomy in eyes with refractory glaucoma.

Background: Pars plana vitrectomy with implantation of an Ahmed glaucoma valve in the vitreous cavity has been reported with a success rate in the management of refractory and neovascular glaucoma. This study aimed to present the outcomes of pars plana Ahmed glaucoma valve (PPAV) surgical implantation in cases with refractory glaucoma.

Methods: In this single-center, retrospective, comparative study, 87 consecutive patients diagnosed with refractory glaucoma who underwent PPAV surgical implantation between October 2015 and October 2019 were evaluated.

Visually significant persistent outer retinal fluid following closure of a macular hole.

Purpose: We report two cases of persistent outer retinal fluid defects following macular hole surgery.

Methods: Twenty-eight consecutive patients who underwent macular hole surgery performed by a single surgeon were examined pre- and postoperatively using slit-lamp biomicroscopy and optical coherence tomography (OCT).

Results: Two patients from this series were identified by OCT as having persistent outer retinal fluid defects after macular hole surgery, despite closure of the holes on biomicroscopy.
