PurposeUltra-thick amniotic membrane grafts derived from the umbilical cord have become available recently. We present a case series describing a new reconstructive technique involving an umbilical cord patch for anterior lamellar reconstruction surgery for severe trichiasis as an alternative to mucous membrane grafting.MethodsThis was a single-center, retrospective clinical case series involving 18 eyes from 12 patients who underwent eyelid margin reconstruction using a lyophilized umbilical cord patch.

- Orbital lesions, which can be either benign or malignant, are difficult to diagnose without invasive procedures such as biopsy or surgery, highlighting the need for noninvasive diagnostic tools.
- This study evaluated the effectiveness of dynamic contrast-enhanced magnetic resonance (MR) imaging at 3T for differentiating between malignant and benign orbital tumors using data from a large group of participants who underwent imaging before surgery.
- Results showed that specific imaging parameters significantly differentiated malignant from benign lesions, with the best model combining various imaging techniques achieving a good diagnostic performance.
Objectives: To differentiate OCVM from other orbital lesions using structural MRI.
Methods: This IRB-approved a historical-prospective cohort single-center analysis of a prospective cohort that included consecutive adult patients presenting with an orbital lesion undergoing a 3T MRI before surgery from December 2015 to May 2021. Two readers blinded to all data read all MRIs assessing structural MRI characteristics.
Purpose: The purpose of this prospective study was to determine the capabilities of intravoxel incoherent motion (IVIM) MRI at 3 Tesla in discriminating between IgG4-related orbital disease (IgG4-ROD) and other causes of orbital inflammation.
Materials And Methods: Main selection criteria for the patients enrolled in this prospective study were age over 18 years and histopathologicaly proven orbital inflammatory lesion. MRI examinations were performed prior to surgery and treatment in all patients with suspected orbital inflammation.
Objectives: Distinguishing benign from malignant orbital lesions remains challenging both clinically and with imaging, leading to risky biopsies. The objective was to differentiate benign from malignant orbital lesions using radiomics on 3 T magnetic resonance imaging (MRI) examinations.
Materials And Methods: This institutional review board-approved prospective single-center study enrolled consecutive patients presenting with an orbital lesion undergoing a 3 T MRI prior to surgery from December 2015 to July 2019.
Intravoxel incoherent motion (IVIM) 3 T MRI for orbital lesion characterization.
Eur Radiol
January 2021
Objectives: To determine the diagnostic accuracy of MRI intravoxel incoherent motion (IVIM) when characterizing orbital lesions, which is challenging due to a wide range of locations and histologic types.
Methods: This IRB-approved prospective single-center study enrolled participants presenting with an orbital lesion undergoing a 3-T MRI prior to surgery from December 2015 to July 2019. An IVIM sequence with 15 b values ranging from 0 to 2000 s/mm was performed.
Quality-based pharmacokinetic model selection on DCE-MRI for characterizing orbital lesions.
J Magn Reson Imaging
November 2019
Background: Although several studies have evaluated dynamic contrast-enhanced (DCE) MRI in the orbit, showing its utility when detecting and diagnosing orbital lesions, none have evaluated the pharmacokinetic models.
Purpose: To provide a quality-based pharmacokinetic model selection for characterizing orbital lesions using DCE-MRI at 3.0T.
Purpose: To better characterize IgG4-related disease (RD) in the setting of idiopathic orbital inflammation syndrome (IOIS).
Methods: National, multicentre, prospective, observational cohort study. Among the patients consecutively included in the French multicentre SIOI cohort, we selected those who underwent orbital and/or adnexal biopsy.
Small Choroidal Melanoma Revealed by a Large Extrascleral Extension.
Ocul Oncol Pathol
September 2017
Aims: Orbital extraocular extension of choroidal melanoma is very rare with small melanomas. We report the case of a patient whose small choroidal melanoma was initially overlooked and was revealed by a large extrascleral extension.
Methods: A 48-year-old Caucasian woman presented with sudden total visual loss in the right eye.
Objectives: To evaluate repeatability of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) parameters in the orbit.
Methods: From December 2015 to March 2016, 22 patients were scanned twice using an IVIM sequence with 15b values (0-2,000 s/mm) at 3.0T.
Successful use of infliximab therapy in sight-threatening corticosteroid-resistant Vogt-Koyanagi-Harada disease.
Ocul Immunol Inflamm
August 2013
Purpose: To report an experience with infliximab in severe corticosteroid-resistant Vogt-Koyanagi-Harada (VKH) disease.
Design: Interventional case series.
Methods: The medical records of 2 adult patients were reviewed.
Purpose: To analyze the contribution of fluorescein angiography (FA) and spectral-domain optical coherence tomography (SD OCT) to the diagnosis of recent choroidal neovascularization (CNV) associated with high myopia.
Design: Retrospective, observational case series.
Methods: Ninety eyes of 73 highly myopic patients (refractive error ≥-6 diopters) with CNV in 1 or both eyes were included.
