Purpose: To evaluate the sensitivity of Spectral Domain Optical Coherence Tomography (SD-OCT) regarding the diagnosis of posterior vitreous detachment (PVD) in vitreomacular interface disorders (VID). Methods: A total of 48 eyes of 48 patients were included in this prospective cohort study. PVD in eyes with VID was investigated. We determined the status of posterior vitreous cortex using slit lamp (SL) biomicroscopy and SD-OCT preoperatively, during vitrectomy and on the intraoperative video recording. Sensitivity and specificity of the examining methods were analysed. Four masked independent examiners participated in this study. Results: PVD was diagnosed in 16 eyes (33.3%) on SD-OCT, 20 eyes (41.7%) on SL examination and 28 eyes (58.3%) during vitrectomy. Sensitivity and specificity for diagnosis of PVD was 37.5% and 31.3% using SD-OCT, 90% and 64.3% on the SL examination, 92.9% and 90% on the video recording respectively, compared to the intraoperative PVD diagnosis. Conclusion: SD-OCT shows a relatively low detection sensitivity of PVD in VID. Thorough OCT investigation is necessary to establish an appropriate diagnosis of PVD and treatment in VID.
Multiple lines of evidence support an immunologic response along with inflammation to be implicated in the pathophysiology of primary rhegmatogenous retinal detachment (RRD) and the development of proliferative vitreoretinopathy (PVR). The purpose of this review is to provide an update on the signaling molecules into the vitreous and subretinal fluid (SRF) involved in these processes. A detailed literature search was performed in PubMed database until November 2021. We identified all papers referring to inflammatory and immunological mediators in the context of primary RRD and in cases complicated by PVR. We analyzed prospective and retrospective cohort studies and reference lists of the retrieved articles. A comprehensive investigation on immunological and inflammatory responses provides significant evidence for the implication of varying signaling molecules in the pathophysiology of RRD and the development of PVR. The reviewed series have revealed that disruption of the normal equilibrium during these processes may be present in the vitreous and SRF of these eyes. The precise role of cytokines, chemokines and growth factors in the pathophysiology of these disorders remains to be clearly elucidated. Overall, immunological and inflammatory signaling molecules are widely implicated in both primary RRD and PVR. The reviewed literature indicates that precise knowledge concerning the pathological milieu sheds light on the underlying pathophysiology and potential therapeutic targets, and highlights unmet needs to be addressed by future research.
Patients in the AMD/ERM group had a higher percentage of subretinal and intraretinal fluid and ellipsoid zone interruption during the follow-up period. Anti-VEGF treatment appeared to have a beneficial effect in both groups, although the AMD/ERM group needed more injections compared to the AMD group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
