The purpose of this paper is to evaluate macular microvascular changes and their correlation with visual outcomes after idiopathic epiretinal membrane (iERM) surgery. Forty-seven eyes operated for iERM were included in this retrospective case series. The foveal avascular zone (FAZ) area, and the vessel density (VD) in the superficial and the deep capillary plexus (SCP and DCP) were evaluated using optical coherence tomography angiography (OCTA).

Methods: Retrospective observational case series of 161 eyes who underwent rhegmatogenous retinal detachment surgery and subsequent silicone oil removal. Pre- and intraoperative risk factors were evaluated using univariate and multivariate logistic regression.
Article Synopsis
- - The study investigated how common metamorphopsia (visual distortion) is after surgery for rhegmatogenous retinal detachment (RRD) and what factors might predict its occurrence.
- - In a group of 107 patients, metamorphopsia prevalence dropped from 51.4% to 29.9% over six months post-surgery, and certain eye structure changes were linked to this improvement.
- - The only preoperative factor that predicted postoperative metamorphopsia was macular detachment, while an assessment tool called M-CHARTS proved effective for predicting recovery in visual distortion after six months.

Background: This study aims to assess and compare the impact of Orthokeratology Double Reservoir Lens (DRL) versus Single Vision Lenses (SVL) on axial elongation and anterior chamber biometric parameters in myopic children over a 6- and 12-month treatment period in France.
Methods: A retrospective study involving 48 patients aged 7 to 17 years, who underwent either orthokeratology treatment or single-vision spectacle correction, was conducted. Changes in refractive error, axial length, and anterior chamber depth were examined.
Introduction: To evaluate the effect of an intravitreal injection of bevacizumab at the time of rhegmatogenous retinal detachment (RRD) surgery, on postoperative proliferative vitreoretinopathy (PVR) in high-risk patients selected by laser flare photometry.
Methods: This single-center observational retrospective cohort study included 137 consecutive patients who underwent pars plana vitrectomy and gas tamponade for primary RRD with increased aqueous flare between July 2016 and June 2021. From June 2019, an intravitreal injection of bevacizumab was administered as an adjunct to RRD repair.
Purpose: To evaluate the effect of the temporal inverted internal limiting membrane (ILM) flap technique compared with that of conventional ILM peeling on the extent of the dissociated optic nerve fiber layer (DONFL) and retinal sensitivity in patients undergoing macular hole (MH) surgery.
Design: Single-center, prospective, open-label, randomized controlled clinical trial.
Participants: Patients requiring vitrectomy for MHs sized > 250 μm.
Purpose: To evaluate macular microvascular changes and their correlation with visual outcomes after rhegmatogenous retinal detachment (RRD) surgery.
Design: Retrospective case series.
Participants: The study included 74 eyes successfully operated for RRD.
Purpose: The aim of the study was to investigate the effect of tamponade duration on retinal changes induced by silicone oil (SO) in patients who underwent successful rhegmatogenous retinal detachment (RRD) surgery.
Methods: Retrospective comparative case series of 68 patients who underwent SO tamponade for RRD. Patients were divided into 2 groups based on timing of SO removal: <6 months (group 1, n = 34) versus ≥6 months (group 2, n = 34).
Article Synopsis
- The study examined 408 eyes undergoing surgery for idiopathic epiretinal membrane (iERM) to find the prevalence of posterior vitreous attachment (PVA) and its preoperative predictive factors.
- About 20.1% of the eyes showed PVA, with axial length and lens status being significant factors; longer axial lengths decreased the odds of PVA, while phakic eyes had a higher risk.
- Despite the occurrence of PVA, it did not impact the surgical outcomes, while factors like shorter axial length and lower preoperative visual acuity were linked to worse visual recovery.*
Background: Rhegmatogenous retinal detachment (RD) involving the macula is a major cause of visual impairment despite high surgical success rate, mainly because of cone death. RD causes the infiltration of activated immune cells, but it is not clear whether and how infiltrating inflammatory cells contribute to cone cell loss.
Methods: Vitreous samples from patients with RD and from control patients with macular hole were analyzed to characterize the inflammatory response to RD.
Purpose: To develop and investigate an evidence-based performance test for assessment of vitreoretinal surgical skills on the EyeSi Surgical Simulator.
Methods: Ten junior residents without any surgical experience, eight senior residents with prior experience in cataract surgery and five vitreoretinal surgeons were included in the study. The test consisted of seven modules and was completed twice by all groups during a single session.
Purpose: To compare the risk of haemorrhagic complications in elective macular surgery between patients with no antithrombotic (AT) treatment (defined as patients with no history of AT therapy or who discontinued AT therapy) and patients who continued AT treatment during the surgery.
Methods: E-case report forms were prospectively recorded in a database before vitreoretinal surgery and 1 month after. Data on patient characteristics, surgical techniques, haemorrhagic complications and antithrombotic status were collected.
Purpose: To evaluate and to compare the anatomical and functional results of phacovitrectomy and pars plana vitrectomy (PPV) alone for phakic rhegmatogenous retinal detachment.
Methods: Retrospective, comparative case series of 266 phakic eyes that underwent either combined phacovitrectomy or PPV alone for primary retinal detachment. The primary anatomical success rate, the final best-corrected visual acuity, and the refractive outcomes were analyzed.
Article Synopsis
- The study investigates the damage to outer retinal layers after surgery for macula-off rhegmatogenous retinal detachment (RRD) and identifies preoperative risk factors.
- A total of 253 eyes were analyzed, showing a high prevalence of defects in outer retinal layers at one month post-surgery, with a notable decrease by six months.
- Longer duration of macular detachment was linked to more damage, while earlier surgery correlated with better visual outcomes and fewer defects, suggesting timely intervention could enhance recovery.
Purpose: To investigate the validity of six vitreoretinal modules on the Eyesi Surgical Simulator.
Methods: Fifteen residents with no vitreoretinal experience and six trained vitreoretinal surgeons (>100 procedures per year) were included in the study. Four modules were selected in agreement with an experienced surgeon: the navigation (Nav), forceps (For), vitrector (Vit) and epiretinal membrane (ERM) peeling modules.
Purpose: To investigate the clinical benefit of internal limiting membrane (ILM) peeling as a surgical adjunct in the repair of primary retinal detachment (RD) complicated by grade B proliferative vitreoretinopathy (PVR).
Design: Retrospective, interventional, comparative case series.
Methods: Setting, study population, observationalprocedures and Main outcome measures.
Background: The study aimed to evaluate outcomes of epiretinal membrane (ERM) peeling in patients with asteroid hyalosis (AH) and to compare them with those from controls without AH.
Methods: This is a retrospective matched cohort study of 1,104 consecutive patients who underwent surgery for ERM between January 2004 and February 2014. Patients with AH were included in the study group and were matched for preoperative visual acuity, age, gender, date of surgery, and axial length with control patients without AH selected from the same cohort.
Purpose: The host immune reaction during endophthalmitis, studied in particular through the intraocular cytokine network, is essential for the comprehension of the disease and the development of new therapies. Therefore, the purpose of this study was to elucidate the cytokine composition of aqueous humor during endophthalmitis.
Methods: In a multicenter case-control study, forty-nine patients with postoperative endophthalmitis and 60 controls (cataract surgery) were included.
Purpose: To evaluate the efficacy and safety of XG-102 (brimapitide) compared to dexamethasone eye drops in the treatment of postoperative ocular inflammation.
Design: Multicenter, randomized, parallel group, double-masked, noninferiority clinical trial.
Methods: Patients who underwent anterior and posterior segments combined surgery or glaucoma surgery or complex posterior segment surgery were eligible to participate.
Purpose: To investigate aqueous flare as a preoperative predictor for later proliferative vitreoretinopathy (PVR) development in patients with rhegmatogenous retinal detachment (RD) and to determine the validity of this measurement in patients at low clinical risk for postoperative PVR.
Methods: This study included 100 eyes of 100 patients who underwent surgery for primary RD. Aqueous flare was determined preoperatively with a laser flare-cell meter (Kowa FM-500, Kowa Company Ltd, Tokyo, Japan).
Aim: To compare early versus delayed intravitreal betamethasone as an adjuvant in the treatment of presumed acute postoperative endophthalmitis after phacoemulsification.
Methods: Patients with presumed postcataract surgery endophthalmitis were included in this prospective, randomised, multicentre study. On admission, patients received intravitreal vancomycin and ceftazidime, and were randomly assigned to intravitreal betamethasone injection (early-IVB) group or no immediate injection (delayed-IVB) group.
