A Croce, V Mastronardi, M Laus, E Festa Kotelnikova
Orbital exenteration is a disfiguring procedure performed for unresponsive orbital infections and control of recurrent benign tumours and malignancies arising from the eyelids (basal cell carcinoma, squamous cell carcinoma, conjunctival malignant melanoma), lachrymal glands (adenoid cystic carcinoma) or surrounding sinuses. In extremely rare cases the use of a prosthetic eye after enucleation can lead to anophthalmic socket tumours. We report the case of a 54-year-old man who had left eye enucleation due to recurring events of retinal detachment and who developed an invasive fast growing epidermoid carcinoma 30 years later...

PURPOSE: This study focuses on characterizing proteasomes in corneal epithelial cells (CEC) and in cultured autologous oral mucosal epithelial cell sheets (CAOMECS) used to regenerate the ocular surface. METHODS: Limbal stem cell deficiency (LSCD) was surgically induced in rabbit corneas. CAOMECS was engineered and grafted onto corneas with LSCD to regenerate the ocular surface. RESULTS: LSCD caused an increase in inflammatory cells in the ocular surface, an increase in the formation of immunoproteasomes (IPR), and a decrease in the formation of constitutive proteasome (CPR)...

PURPOSE: To evaluate corneal innervation and inflammatory cell infiltration using in vivo confocal microscopy (IVCM) and to correlate these findings with subjective symptoms of dry eye, as measured by the Ocular Surface Disease Index (OSDI) in patients with non-Sjögren's (NSDE) and Sjögren's syndrome dry eyes (SSDE). METHODS: Central corneal images were prospectively captured from 10 age-matched healthy control eyes, 24 eyes with clinically diagnosed NSDE and 44 eyes with clinically diagnosed SSDE, using IVCM (HRT III RCM)...

PURPOSE: To quantify the severity of ocular pain in patients with dry eye disease (DED) and evaluate factors associated with pain severity. DESIGN: Cross-sectional study. METHODS: Eighty-four patients with DED were asked to score their severity level of ocular pain using a 10-point scale, with 10 indicating the most severe pain. All patients also had a comprehensive ophthalmic assessment including a detailed history, Ocular Surface Disease Index (OSDI) questionnaire, and ocular surface examination...

PurposeFungal keratitis is relatively rare in temperate climates with only one previous population-based study, which reported a minimum annual incidence of 0.32 per million population in the United Kingdom. We performed a nationwide study in the Republic of Ireland of cases over a 6-year period to establish the incidence, risk factors, treatment, and outcomes of fungal keratitis.Patients and methodsAll corneal scraping specimens positive for fungal species over a 6-year period were identified at the microbiology departments of the seven main ophthalmology units in the Republic of Ireland...

The purpose of this study was to describe a possible causal relationship between ocular cicatricial pemphigoid (OCP) and ocular surface squamous neoplasia. Two middle-aged female patients with already diagnosed OCP were studied in regard to the subsequent onset of conjunctival squamous neoplasia. Their clinical histories, ocular examinations, clinical photographs, and results of biopsies and any ancillary immunofluorescent laboratory evaluation studies were carefully reviewed. One patient had a preinvasive squamous dysplasia and the other an invasive squamous cell carcinoma, both in the unequivocal setting of OCP with bilateral conjunctivitis, symblephara, and forniceal foreshortening...

PURPOSE: To investigate whether blood glucose regulation in patients with diabetes mellitus (DM) has an influence on the ocular surface disease index (OSDI) score and tear function tests such as tear film osmolarity (TFO), tear break-up time (TBUT) and Schirmer tests. METHODS: Fifty diabetic patients with a fasting blood glucose (FBG) level greater than 200mg/dL and HbA1c level greater than 10% were recruited for this prospective study. All of the patients underwent a detailed ophthalmic examination including OSDI questionnaire, TFO test, TBUT test and Schirmer test initially...

Dry eye disease (DED) is a common ocular disorder affecting millions of individuals worldwide. The pathology of DED involves the infiltration of CD4(+) lymphocytes, leading to tear film instability and destructive inflammation. In the healthy steady state, a population of immunosuppressive T-cells called regulatory T-cells (Treg) regulates proliferation of immune cells that would otherwise lead to a disruption of immunological homeostasis. For this reason, it has been suggested that Tregs could restore the immunological imbalance in DED...

REVIEW
Daddi Fadel
The evolution of scleral lenses has led to new formulations of scleral fitting concepts and designs. The diameters of modern scleral lenses have been overhauled too and they are smaller comparing to the original ones. Nowadays, prescription of mini-sclerals supposedly seems in major extension and it appears indeed the necessity of some practitioner to differentiate the smaller mini-scleral lenses from larger mini-scleral lenses empathizing that they are the "smaller" ones. Therefore, it is maybe, necessary a definition of mini-scleral lenses referring to the landing zone width in relation to the horizontal visible iris diameter (HVID) and the limbus extension...

PURPOSE: To examine the relationship between ocular surface disease (OSD) and topical antiglaucoma therapy. METHODS: A total of 211 eyes of 211 patients with open-angle glaucoma or ocular hypertension on topical medication were recruited over 10 months. Controls were 51 eyes of 51 healthy age- and sex-matched volunteers. In each patient, we recorded the intraocular pressure-lowering eyedrops used, the number of medications used, and daily and cumulative preservative concentrations (PC)...

Corneal neovascularization (CNV) is a common pathological change in ocular surface diseases. It is not only the factor that affects vision, but also the main cause for corneal graft failure. Based on the mechanism of CNV, many achievements have been developed to suppress the formation of CNV. There are certain novel drugs such as aflibercept, gold nanoparticles and netrins which provide us with new clues to treat CNV. However, we still need to develop more effective therapeutic drugs. It is of great significance to develop new effective drugs to suppress the occurrence of CNV...

Zika virus (ZIKV) is a re-emerging mosquito-borne flavivirus that has recently caused extensive outbreaks in Central and South America and the Caribbean. Given its association with Guillain-Barré syndrome in adults and neurological and ocular malformities in neonates, ZIKV has become a pathogen of significant public health concern worldwide. ZIKV shares a considerable degree of genetic identity and structural homology with other flaviviruses, including dengue virus (DENV). In particular, the surface glycoprotein envelope (E), which is involved in viral fusion and entry and is therefore a chief target for neutralizing antibody responses, contains regions that are highly conserved between the two viruses...

BACKGROUND To determine the association between serum 25(OH)D and dry eye syndrome (DES) incidence. This study was also designed to determine whether serum 25(OH)D levels were associated with ocular parameter of DES patients. MATERIAL AND METHODS This is a case-control study with 70 DES cases and 70 healthy controls. Clinical data included body mass index (BMI, kg/m²), smoking history, diabetes, and blood pressure. Serum 25(OH)D was chosen as the main parameter and reflected the level of vitamin D. The DES parameters included ocular surface disease index (OSDI) scales, tear film breakup time (TBUT) and Schirmer test I...
