Purpose: To report the characteristics of a macular detachment associated with peripapillary intrachoroidal cavitation (ICC) and the outcomes of vitrectomy.
Methods: The medical records of 69 eyes of 61 patients who underwent vitrectomy for macular detachment or macular retinoschisis but without vitreomacular traction or optic disc pit were reviewed. Optical coherence tomography was used to determine the morphology of the ICC. The outcomes of vitrectomy including the creation of a posterior vitreous detachment and internal limiting membrane peeling were evaluated.
Results: An ICC was detected in 3 of 3 eyes without pathologic myopia but none in 66 eyes with pathologic myopia (P < 0.0001). Myopic peripapillary conus was present in all 3 eyes, tilted disc in 2 eyes (67%), posterior staphyloma in 1 eye (33%), and no preoperative posterior vitreous detachment in all eyes. Optical coherence tomography detected a connection between the vitreous cavity and the ICC in two eyes with pit-like splitting and between the subretinal space and the ICC in two eyes. The macular detachment was resolved 5 months to 6 months postoperatively with improvement of vision.
Conclusion: A macular detachment with ICC can be present in nonpathological myopic eyes. Vitreous surgery to create a posterior vitreous detachment with internal limiting membrane peeling may help resolve the macular detachment.

Fondation Asile des Aveugles, Department of Ophthalmology, Jules-Gonin Eye Hospital, University of Lausanne, Avenue de France 54, Lausanne, 1001, Switzerland.
Background: This study evaluates the efficacy of intravitreal Faricimab in reducing pigment epithelium detachment (PED) and fluid volumes in both treatment-naïve eyes and eyes unresponsive to anti-VEGF mono-therapies, all diagnosed with type 1 macular neovascularization (T1 MNV) over a period of 12-month.
Methods: A retrospective, single-center cohort study was conducted at the Jules Gonin Eye Hospital, Lausanne, Switzerland. Clinical records of treatment-naïve and non-responder switch patients presenting T1 MNV secondary to neovascular age-related macular degeneration (nAMD) from September 2022 to March 2023 were reviewed.

Background: Retinal pigment epithelium (RPE) tear is a well-known complication of RPE detachment and is typically associated with significant visual acuity decline. However, in this case, despite the occurrence of an RPE tear there was an unexpected improvement in visual acuity.
Case Presentation: A 68-year-old male presented with blurred vision in his right eye of a month's duration.

Department of Ophthalmology, Kanazawa University Graduate School of Medical Science, Kanazawa, Japan.
Purpose: The factors that contribute to the progression of macular involvement in RRD have not been extensively investigated. The purpose of this study is to evaluate the association between the preoperative characteristics and macular status of the eyes with rhegmatogenous retinal detachment (RRD).
Methods: This is a retrospective cohort study.

Central serous chorioretinopathy (CSC) is a known side effect of systemic steroid therapy. The role of intravitreal steroids in causing CSC is controversial. We present two cases of acute CSC that developed after intravitreal steroid injections.

Proliferative diabetic retinopathy (PDR) is the most severe complication of chronic hyperglycaemi stimulates oxidative stress that changes the retinal basement membrane function and provokes neovascularization, macular edema and retinal detachment. But an oxidative-antioxidant biomarker assessment in ocular matrices, such as aqueous humor (AH) and vitreous, might show the oxidative stress (OS) status in the posterior segment. Here, we show a cross-sectional analytical study of 39 patients who had a vitrectomy and assess the levels of different oxidative-antioxidant biomarkers in blood, aqueous and vitreous humor in three groups: diabetes mellitus 2 (DM2) with PDR [DM(+)PDR(+)] ( =13), DM2 without PDR [DM(+)PDR(-)] ( = 13) and non-DM2 non-PDR [DM(-)PDR(-)] as the control group ( = 13).
