Importance: The clinical diagnosis of conjunctival and eyelid margin tumors is challenging, and new noninvasive imaging techniques could be valuable in this field. Objective: To assess the diagnostic accuracy of handheld in vivo reflectance confocal microscopy (IVCM) for the diagnosis of eyelid margin and conjunctival tumors. Design: A prospective observational study was conducted at University Hospital of Saint-Etienne from January 2, 2011, to December 31, 2016 (inclusion of patients until December 31, 2015, and follow-up until December 31, 2016)...

BACKGROUND: Intraventricular cavernous malformations (IVCMs) are relatively rare benign vascular malformations. Patients may be asymptomatic or present with symptoms including headache, seizure, hemorrhage, and neurological deficits. We report two cases of patients with cavernomas in the third ventricle and at the foramen of Monro (FoM) and a systematic review of the literature to examine the clinical features and the efficacy of the current standard of care for these lesions. METHODS: A systematic review was performed according to PRISMA guidelines...

Purpose: To examine the preoperative conjunctival dendritic cell density (DCD), goblet cell density (GCD), and stromal meshwork reflectivity (SMR) in glaucomatous patients undergoing filtration surgery, using in vivo confocal microscopy (IVCM). Methods: Sixty-six patients were enrolled. At baseline, IVCM was performed at the site planned for surgery, and was repeated after 12 months at bleb site. Surgery was successful when a one-third reduction of baseline IOP was obtained at the last follow-up...

BACKGROUND: Catheter associated urinary tract infections (CAUTI) account for about 25% of nosocomial infections globally and often result in increased morbidity and healthcare costs. An added concern is the presence of microbial biofilms which are major reservoirs of bacteria, especially antibiotic resistant bacteria, in catheters. Since the practice of the closed drainage system, innovations to combat CAUTI have not produced significant improvements in clinical outcomes. The lack of a robust laboratory platform to test new CAUTI preventive strategies may impede development of novel technologies...

Ocular surface diseases (OSDs) represent a widely investigated field of research given their growing incidence and the negative impact on quality of life. During OSDs, cytokines generated by damaged epithelia trigger and deregulate the lymphoid cells composing the eye-associated lymphoid tissues, inducing an immune-mediated chronic inflammation that amplifies and propagates the disease during time. The conjunctiva-associated lymphoid tissue (CALT), given its particular position that permits immune cells covering the cornea, might play a crucial role in the development of OSDs...

SUMMARY: The use of in vivo confocal microscopy (IVCM) is rapidly emerging as an important clinical tool to evaluate changes in corneal sensory nerves as a surrogate measure for diabetic peripheral neuropathy. Commonly used metrics to document and grade the severity of diabetes and risk for diabetic peripheral neuropathy include nerve fiber length, density, branching and tortuosity. In addition to corneal nerves, thinning of the retinal fiber layer has been shown to correlate with the severity of diabetic disease...

AIM: Corneal keratectasia is one of the complications associated with laser in situ keratomileusis (LASIK) that results in vision impairment. The pathogenesis of post-LASIK ectasia (PLE) remains underexplored. We report the tear cytokine profile and in vivo confocal microscopy (IVCM) findings in eyes with PLE. METHODS: This retrospective study included age-matched 7 (14 eyes) post-LASIK controls (PLCs) and 6 (12 eyes) PLE subjects. Corneal topography was used to categorise the subjects into PLC and PLE groups...

Purpose: The purpose of this study was to evaluate the efficacy of new viscous cysteamine hydrochloride (CH) eye drops (vCH 0.55%) compared with standard CH 0.10% drops treatment. Methods: This was an open-label, phase III, randomized, two-arm multicenter trial conducted at two centers in France. Cystinosis patients ≥2 years old were randomized 1:1 to receive eye drops, four times per day for 90 days in both eyes. We compared the superiority in reducing corneal cystine crystal density as assessed by in vivo confocal microscopy (IVCM)...

PURPOSE: To describe the morphological features of the corneal epithelial layers, subbasal nerve plexus, stroma, and endothelium in patients with mucous membrane pemphigoid (MMP) as shown by in vivo confocal microscopy (IVCM). METHODS: Central corneal images were captured from 10 healthy age-matched control eyes and 30 eyes with clinically diagnosed MMP by in vivo laser scanning confocal microscopy (HRT III RCM). Morphological changes of the corneal epithelial layers, stroma, and endothelium, characteristics of corneal nerves, and presence of inflammatory dendritic cells (DCs) were evaluated...

AIM: To determine typical corneal changes of congenital aniridic keratopathy (CAK) using corneal topography and confocal systems, and to identify characteristics that might assist in early diagnosis. METHODS: Patients with CAK and healthy control subjects underwent detailed ophthalmic examinations including axial length, corneal thickness, tear film condition, corneal topography, and laser-scanning in vivo confocal microscopy (IVCM). RESULTS: In early stage aniridic keratopathy, Schirmer I test (SIT), break-up time (BUT), mean keratometry (mean K) and simulated keratometry (sim K) were reduced relative to controls (P<0...

PURPOSE: To assess the interrelationship of different methods of measuring the demarcation line depth after corneal collagen crosslinking (CXL). SETTING: University eye clinic, Oslo, Norway. DESIGN: Prospective case series. METHODS: Eyes having CXL for progressive keratoconus were evaluated 1 month after CXL by in vitro confocal microscopy (IVCM), optical coherence tomography (OCT), and Scheimpflug imaging. When applying IVCM, the depth of the CXL demarcation line was measured with 2 methods; that is, IVCM keratocyte disappearance and IVCM intensity increase...

BACKGROUND: Pre-Descemet corneal dystrophy (PDCD) is characterized by the presence of numerous, tiny, polymorphic opacities immediately anterior to Descemet membrane, which is a rare form of corneal stromal dystrophy and hard to be diagnosed. In vivo confocal microscopy (IVCM) is a useful tool to examine the minimal lesions of the cornea at the cellular level. In this article, we report a rare case of PDCD associated with X-linked ichthyosis and evaluate IVCM findings. CASE PRESENTATION: We present a 34-year-old male Chinese patient with PDCD associated with X-linked ichthyosis...

BACKGROUND/AIMS: To describe in vivo confocal microscopy (IVCM) features of microsporidial keratoconjunctivitis in immunocompetent adult patients. METHODS: Patients suspected clinically to be suffering from microsporidial keratoconjunctivitis (ie, presence of unilateral follicular and/or papillary conjunctivitis in conjunction with multifocal, coarse corneal epitheliopathy) were subjected to IVCM with the Rostock Cornea Module of the Heidelberg Retinal Tomograph 3, and combined potassium hydroxide and calcofluor white (KOH+CFW) staining of the corneal scrapings, to detect the microsporidial spores...

BACKGROUND: Clinical outcomes in fungal keratitis vary between Fusarium and Aspergillus spp, therefore distinguishing between species using morphological features such as filament branching angles, sporulation along filaments (adventitious sporulation) or dichotomous branching may be useful. In this study, we assessed these three features within Heidelberg Retina Tomograph 3 in vivo confocal microscopy (IVCM) images from culture-positive Fusarium and Aspergillus spp keratitis participants...

Purpose. To assess the clinical and morphological outcomes of topography-guided accelerated corneal cross-linking. Design. Retrospective case series. Methods. 21 eyes of 20 patients with progressive keratoconus were enrolled. All patients underwent accelerated cross-linking using an ultraviolet-A (UVA) exposure with an energy release varying from 7.2 J/cm(2) up to 15 J/cm(2), according to the topographic corneal curvature. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, topography, in vivo confocal microscopy (IVCM), and anterior segment optic coherence tomography (AS-OCT) were evaluated preoperatively and at the 1, 3, 6, and 12 months postoperatively...
