Abstract

Purpose : The interaction between the peripheral vitreous and retina is closely related to the pathogenesis of rhegmatogenous retinal detachment (RRD). The purpose of this study was to observe the peripheral vitreous and retina in cases of RRD using intraoperative optical coherence tomography (iOCT). We have developed an observation technique for the peripheral vitreous and retina using iOCT to objectively evaluate the peripheral lesion of the fundus (Nishitsuka K et al. RETINA in press).

Methods : This retrospective study included 50 eyes of 50 patients (mean age 59.42 ± 10.80 years) who underwent vitrectomy for RRD at the Yamagata University Hospital between September 2015 and September 2016. Each patient was treated using 25-gauge pars plana vitrectomy by one surgeon (K.N.). During vitreous shaving with indentation, peripheral findings of vitreous and retina were analyzed by radial 3-mm B-scanning using iOCT RESCAN. OCT images were analyzed postoperatively.

Results : In all cases, the angle formation between the retina and the detached posterior vitreous membrane around the vitreous base was detected using iOCT. Cystoid degeneration was detected on the peripheral retina of 28 eyes (56%). Moreover, cystoid degeneration was detected around the retinal tear (5 cases), at the detached retinal area (8 cases), and at the attached retinal area (14 cases). In all cases, cystoid degeneration was detected from near the posterior to the anterior vitreous base. Peripheral vitreous was adhered to the cystoid degeneration of the retina.

Conclusions : The iOCT results indicate that cystoid degeneration might be a manifestation of the tractional peripheral retinal detachment of the peripheral vitreous that is suggestive of the pathogenesis of RRD.

This is an abstract that was submitted for the 2018 ARVO Annual Meeting, held in Honolulu, Hawaii, April 29 - May 3, 2018.
