Background: Treatment for Graves' hyperthyroidism (GH) in patients with orbitopathy (GO) remains a topic of debate. This study aimed to investigate the outcome GO following glucocorticoids, depending on chosen thyroid treatment. Methods: retrospective cohort included 49 consecutive GH and moderate-to-severe, active GO, as defined by European Group Orbitopathy guidelines. Twenty-four were treated radioactive iodine (RAI) 25 methimazole (MMI). All administered intravenous methylprednisolone....

Background Though several procedures of IOL implantation have been described (sutured scleral fixation, intra-scleral angle-supported anterior chamber, and chamber or retropupillary iris-claw IOLs), there are no randomized trials which comparing different techniques. Hence, the surgical treatment aphakia still remains controversial challenging. The purpose this study was to compare long-term efficacy rate complications versus posterior Iris-claw intraocular lenses (IOL) correct for without...

Abstract Objectives A beneficial effect of sirolimus in Graves’ orbitopathy (GO) was reported, suggesting a possible use clinical practice. We conducted an observational, single-centre, no-profit, study to investigate the efficacy as second-line treatment for moderate-to-severe, active GO compared with methylprednisolone. Methods Data from consecutive patients given (2 mg orally on first day, followed by 0.5 mg/day 12 weeks) or methylprednisolone [500 iv/weekly (6 weeks), 250 mg/weekly...

Keratoplasty is one of the irreplaceable treatment options for corneal diseases. Currently, there no evidence to substantiate that harvested grafts from COVID-19 patients can contain SARS-CoV-2 virus and lead a systemic infection. Although risk transmission through stromal tissue low, it potentially exists. Lack clinical data, unclear potential donor-derived infection non-established recommendations transplantation during pandemic have resulted in dramatic reduction number keratoplasty...

Although the expression of microRNAs (miRNAs) in retinal pigment epithelial (RPE) cells undergoing epithelial-mesenchymal transition (EMT) is involved pathogenesis proliferative vitreoretinopathy (PVR), its vitreous patients with primary detachment (RD) and different PVR grading has not yet been investigated. We assessed miRNAs humor (VH) diagnosed RD PVR.The VH was extracted from core chamber who had undergone standard vitrectomy for RD. RNA TaqMan Low-Density Arrays (TLDAs) were used miRNA...
