Flow cytometric analysis of conjunctival epithelium in ocular rosacea and keratoconjunctivitis sicca

2000

Abstract Purpose To investigate by flow cytometry and impression cytology (IC) specimens the inflammatory status of the conjunctival epithelium and goblet cell density in two series of patients with rosacea and dry eye syndrome compared with a population of healthy subjects. Design Nonrandomized, prospective, comparative case series. Participants Twenty-six eyes of 13 patients with rosacea, 26 eyes of 13 patients with dry eye syndrome, and 24 eyes of 12 control subjects were included in this study. Methods IC specimens were collected after clinical examination of the ocular surface and analyzed by flow cytometry, using antibodies directed to human lymphocyte antigen-DR (HLA-DR), intercellul…

Topical Voriconazole as Supplemental Treatment for Acanthamoeba Keratitis

2020

Purpose Voriconazole was shown to inhibit ergosterol synthesis in various acanthamoeba species. The purpose of this study was to evaluate the clinical outcome of treatment with supplemental topical voriconazole in patients with acanthamoeba keratitis (AK). Methods All patients who had been treated for AK with voriconazole 1% drops in conjunction with topical first-line antiacanthamoeba therapy composed of polyhexamethylene biguanide (PHMB) 0.02% and propamidine isethionate 0.1% (Brolene) between November 2014 and August 2017 at the Department of Ophthalmology, University Medical Center Mainz, were included. The main outcomes were treatment failure and recurrence rate. Secondary outcomes wer…

Autoimmune ear disease: clinical and diagnostic relevance in Cogan’s sydrome

2017

The autoimmune inner ear disease is a clinical syndrome with uncertain pathogenesis that is often associated to rapidly progressive hearing loss that, especially at the early stages of disease, may be at monoaural localization, although more often it is at binaural localization. It usually occurs as a sudden deafness, or a rapidly progressive sensorineural hearing loss. In this study a particular form of autoimmune inner ear disease is described, Cogan’s syndrome. Cogan’s syndrome is a chronic inflammatory disorder that most commonly affects young adults. Clinical hallmarks are interstitial keratitis, vestibular and auditory dysfunction. Associations between Cogan’s syndrome and systemic va…

The use of in vivo confocal microscopy in fungal keratitis – Progress and challenges

2022

Fungal keratitis (FK) is a serious and sight-threatening corneal infection with global reach. The need for prompt diagnosis is paramount, as a delay in initiation of treatment could lead to irreversible vision loss. Current “gold standard” diagnostic methods, namely corneal smear and culture, have limitations due to diagnostic insensitivity and their time-consuming nature. PCR is a newer, complementary method used in the diagnosis of fungal keratitis, whose results are also sample-dependent. In vivo confocal microscopy (IVCM) is a promising complementary diagnostic method of increasing importance as it allows non-invasive real-time direct visualization of potential fungal pathogens and mani…

Methotrexate as a treatment in ocular cicatricial moderate pemphigoid.

2013

Abstract Clinical case A 73 year-old woman presented with a history of non-specific symptoms and photophobia in both eyes of 1 year progression. The examination revealed a bilateral symblepharon and fornix shortening. Immunohistochemical analysis confirmed the presence of linear deposits of IgG, IgM and C3 along the conjunctival basement membrane. With the diagnosis of ocular cicatricial pemphigoid, systemic treatment with subcutaneous methotrexate was prescribed. Discussion We consider such treatment a very effective initial immunosuppressive alternative in patients with moderate conjunctival inflammation and in cases of rapid progression.

Propolis-Based Nanofiber Patches to Repair Corneal Microbial Keratitis

2021

In this research, polyvinyl-alcohol (PVA)/gelatin (GEL)/propolis (Ps) biocompatible nanofiber patches were fabricated via electrospinning technique. The controlled release of Propolis, surface wettability behaviors, antimicrobial activities against the S. aureus and P. aeruginosa, and biocompatibility properties with the mesenchymal stem cells (MSCs) were investigated in detail. By adding 0.5, 1, and 3 wt.% GEL into the 13 wt.% PVA, the morphological and mechanical results suggested that 13 wt.% PVA/0.5 wt.% GEL patch can be an ideal matrix for 3 and 5 wt.% propolis addition. Morphological results revealed that the diameters of the electrospun nanofiber patches were increased with GEL (from…

Successful Topical Application of Caspofungin in the Treatment of Fungal Keratitis Refractory to Voriconazole

2010

Fungal keratitis is an important ophthalmic problem because it leads to corneal blindness and sometimes to loss of the eye.1,2 There is no agreed protocol for the treatment of suspected fungal keratitis. Topical and oral voriconazole have now been reported to be effective.3 However, some cases do not respond to this treatment. New antifungal agents such as caspofungin acetate, 0.5%, are promising alternatives

Anti-inflammatory effects of GLA and EPA on a scopolamine-induced dry eye rat model

2007

International audience; Purpose:: The aim of this study was to evaluate the potential anti-inflammatory effects of dietary γ-linolenic acid (GLA) and eicosapentaenoic acid (EPA) in a scopolamine-induced dry eye rat model. Methods:: Female Lewis rats were fed with 5%-lipid diets containing 10% of either GLA or EPA. After two months of feeding, we induced dry eye syndrome using scopolamine continuously delivered via osmotic pumps for 2, 10 and 28 days. At the end of the treatment period, we performed fluorescein staining on the cornea. We sacrificed the animals and excised the ocular tissues and the exorbital lacrimal glands. We immunostained MHCII and mucin MUC5AC on ocular sphere cryosectio…

Queratitis bacteriana por Moraxella nonliquefaciens

2020

Moraxella keratitis can lead to important complications. Moraxella nonliquefaciens(M. nonliquefaciens) has the worst prognosis. Only three cases of corneal infections due to M. nonliquefaciens have been published. The case is presented of a 79-year-old man with bullous keratopathy, recently affected with severe infectious keratitis. Dense, deep, and central stromal infiltrates and hyphaema were detected. After the identification of M. nonliquefaciens in the culture, and given the progression of the condition, the initial empirical treatment was modified to topical ciprofloxacin and ceftazidime in accordance with the antibiogram, combining oral ciprofloxacin and amoxicillin-clavulanate. Afte…
