Changes in choroidal area after intraocular pressure reduction following trabeculectomy
Purpose To investigate changes of the macular and peripapillary choroidal areas after trabeculectomy. Methods This prospective and interventional study examined 74 eyes of 74 patients with glaucoma uncontrolled by medical therapy. Enhanced depth imaging optical coherence tomography (EDI-OCT) recorded macular and peripapillary choroidal images at 1 day before trabeculectomy and at 2 weeks after surgery. The Niblack method was used to covert luminal and interstitial areas to binary images.doi:10.1371/journal.pone.0201973 pmid:30133501 fatcat:lflknlogibb6pah7dhillxvkfq
