PurposeThe purpose of this study is to investigate the reperfusion of translocated retinal pigment epithelium (RPE)-choroid graft in the treatment of patients with neovascular age-related macular degeneration (nAMD), using OCT angiography (OCTA), a novel non-invasive, high-resolution imaging modality.Patients and methodsEighteen eyes of 18 consecutive patients suffering from complicated nAMD underwent RPE-choroid patch graft translocation surgery using a peripheral retinotomy and flap-over technique. We analyzed functional and anatomical outcome using visual acuity, Spectral Domain OCT and OCTA.ResultsWith a mean follow-up of 11 months, out of 18 patients, 15 gained vision, 1 remained stable, and 2 lost vision. Overall, the visual acuity improved with a mean of 30 letters. Perfusion of the graft tissue was confirmed in all patients. Two patients developed signs of a recurrent neovascular membrane during follow-up. No cases of proliferative vitreoretinopathy occurred in this series.ConclusionsOCTA images show signs of perfusion in all grafts. Encouraging functional results and low risk of severe complications suggest that RPE-choroid graft translocation is a valid option in patients with complicated nAMD.

Article Synopsis
  • Emerging research suggests that metformin may help prevent age-related macular degeneration (AMD) by affecting the gut microbiome and reducing choroidal neovascularization (CNV) in a mouse model.
  • The study involved administering metformin to specific pathogen-free male mice and assessing the size of CNV and changes in gene expression in the retinal pigment epithelium, as well as analyzing gut microbiota composition.
  • Results showed that metformin significantly reduced CNV size and macrophage infiltration, altered gene expression related to angiogenesis, and modified gut microbiota, indicating that the gut microbiome plays a role in metformin's protective effects against AMD.

Purpose: To evaluate the outcomes and complications after different surgical management of cases with significant sumacular hemorrhage (SMH) of size more than 4 disc diameter (DD).

Methods: It was a retrospective interventional study. All consecutive 103 cases of significant SMHs were treated by vitrectomy and divided into three groups.

Article Synopsis
  • * The study identified around 500 lipid species in human blood and eye tissues using a combination of hydrophilic interaction liquid chromatography (HILIC) and reversed-phase chromatography (RPC), along with high-resolution mass spectrometry.
  • * While RPC was better at detecting hydrophobic lipids, HILIC excelled in separating polar lipids; using both methods together enhanced the analysis of lipid classes, providing valuable insights into lipid metabolism and its implications for diseases.

Purpose: Five patients who underwent uncomplicated retinal pigment epithelium (RPE)-choroid transplantation for neovascular age-related macular degeneration developed a destructive inflammatory reaction causing subretinal fluid accumulation and extensive RPE atrophy in the graft. We hypothesized that this inflammation could be caused by an auto-immune response against the graft, resulting in circulating auto-antibodies. The aim of our study was to examine a potential autoimmune origin, which would allow a more targeted therapy approach.

Introduction: This study investigates the incidence, clinical characteristics, and treatment response of macular neovascularization (MNV) occurring after retinal pigment epithelium (RPE) and choroid graft translocation surgery (RPE-choroid TS).

Methods: Retrospective analysis of 36 eyes of 36 consecutive patients who underwent RPE-choroid TS. Longer term follow-up of graft survival focusing on the occurrence of MNV was performed using multimodal imaging.
