Updates on the utility of anterior segment optical coherence tomography in the assessment of filtration blebs after glaucoma surgery.

Acta Ophthalmol 2021 May 4. Epub 2021 May 4.

Centro Internacional de Oftalmologia Avanzada, Madrid, Spain.

The formation of filtration blebs is the main drainage mechanism for reducing intraocular pressure after traditional incisional glaucoma surgery such as trabeculectomy and non-penetrating deep sclerotomy. Early and short-lasting blebs may also occur after canaloplasty. Bleb formation also plays an important role after the implantation of glaucoma drainage devices, including Minimally Invasive Glaucoma Surgery devices. Read More

Eur J Ophthalmol 2021 Apr 15:11206721211009446. Epub 2021 Apr 15.

Department of Ophthalmology, Shri Jagdamba Charitable Eye Hospital, Sri Ganganagar, Rajasthan, India.

Background: The purpose of this paper is to delineate a technique of using a 23G, single, sutureless transconjunctival pars plana sclerotomy to facilitate anterior segment surgery in eyes with increased positive vitreous pressure (PVP) ascribe to predisposing or intraoperative factors.
