Application of optic disc parameters and RNFL thickness by swept source optical coherence tomography in patients with PACG

Abstract

AIM: To explore the application value of optic disc parameters and retinal nerve fiber layer(RNFL)thickness by swept source optical coherence tomography(SS-OCT)in the efficacy evaluation of primary angle-closure glaucoma(PACG). METHODS: Totally 60 PACG patients(68 eyes)who was treated with peripheral iridotomy and trabeculectomy was selected. According to the intraocular pressure during postoperative follow-up, all the patients were divided into controlled group(RESULTS: The intraocular pressure in both groups were significantly reduced after treatment, and the controlled group was significantly lower than that in uncontrolled group(PP>0.05), but it was obviously thinned in uncontrolled group compared with before treatment and control group(PPPr=0.415, -0.399; PCONCLUSION: SS-OCT can accurately reflect the change of optic disc parameters and RNFL thickness after intraocular pressure controlled in PACG patients. It has a certain clinical value in follow-up and efficacy evaluation for PACG.
