: Approximately a quarter of the world's population at some point in life is at risk of developing shingles (Herpes Zoster). In 10-20% of cases the first branch of the trigeminal nerve gets involved (Herpes Zoster Ophthalmicus, HZO). Ophthalmic complications of HZO are able to cause a significant reduction in visual function. AIM: To study and summarize clinical features of HZO (including the rate of complications and their nature) and to determine the relationship between clinical and laboratory data from these patients...

BACKGROUND: Ocular herpes is a viral infection of the eye caused by the herpes simplex virus (HSV), a double-stranded DNA virus. Corneal scarring caused by herpes simplex keratitis (HSK) is the leading infectious cause of penetrating corneal graft in high-income countries. Acyclovir is an antiviral drug known to have a protective effect against recurrences in herpetic eye disease. While there are some studies which have evaluated the effects of intervention with oral antiviral in preventing such recurrences in people with corneal grafts, a systematic review of all comparative clinical trials has not been previously undertaken...

The aim of the present study was to investigate the efficacy of a novel surgical intervention, excisional keratectomy combined with focal cryotherapy and amniotic membrane inlay (EKCAI), for the treatment of recalcitrant filamentary fungal keratitis. A retrospective analysis was performed of patients who underwent excisional keratectomy combined with conjunctival flap inlay (EKCFI), EKCAI or therapeutic penetrating keratoplasty (TPK) from January 2006 to January 2011. Recalcitrance was determined as being unresponsive to standard medical antifungal therapy for at ≥1 week...

PURPOSE: The purpose of this study was to evaluate the clinical utility of SG17, an ophthalmic antimicrobial susceptibility measurement plate. DESIGN: This was a multicenter, retrospective, observational study. PATIENTS AND METHODS: Using clinical isolates from patients with ocular infections, drug susceptibility testing using the Clinical Laboratory and Standards Institute standards was routinely conducted at five facilities. The minimum inhibitory concentrations of the isolated strains were determined using SG17 at the Research Foundation for Microbial Diseases of Osaka University...

The present report discusses a new case of dacryoadenitis with extraocular muscle inflammation associated with Acanthamoeba keratitis (AK) in a contact lens wearer. A 41-year-old male, who has worn silicone hydrogel contact lenses on an extended basis for about 10 years, attended with the complaints of vision disturbance, hyperemia, and pain in his right eye. His history revealed that 1.5 month ago, he had been diagnosed with allergic conjunctivitis and had used steroid eye drops. Biomicroscopic examination revealed eyelid edema, chemosis, and ring infiltration, radial keratoneuritis and an epithelial defect in the cornea...

PURPOSE: To evaluate the quality of life (QoL) in patients with quiescent herpes simplex keratitis compared with control patients without ocular herpes. DESIGN: Prospective, case-control study. PARTICIPANTS: Thirty-three patients with a unilateral and relapsing herpes simplex keratitis (HSK group) that was quiescent during evaluation (no acute episode in the past 3 months) and 66 patients with no history of HSK (control group). Both groups were age and gender matched...

OBJECTIVE: To determine whether horses with clinically diagnosed Equine Recurrent Uveitis (ERU) and those with Leptospirosis infection have a specific cytokine profile in their aqueous humor (AH) and serum that differs from horses with uveitis secondary to other ocular inflammatory processes and from horses with normal eyes. ANIMALS STUDIED: Twenty-five client-owned horses with uveitis that were presented to the North Carolina State University Ophthalmology Service, and four University-owned horses without history or clinical signs of ocular disease...

PURPOSE: To report a unique case of peripheral ulcerative keratitis secondary to hepatitis B virus (HBV)-associated cryoglobulinemia and vasculitis and its pharmacological and surgical treatment and 2-year follow-up. METHODS: A 52-year-old woman presented with unilateral eye pain and photophobia, arthralgia, remnants of a maculopapular rash, and subsequently facial numbness several weeks later.

PURPOSE: The aim of this paper is to report the successful management of the first case of Lasiodiplodia theobromae keratitis in Hong Kong. METHODS: We conducted a case report. RESULTS: A 43-year-old Chinese male with a history of diabetes developed left eye keratitis after a trauma during tree felling. Fungal keratitis was diagnosed using a confocal microscope on day 1, and L. theobromae was confirmed from the culture. He was given oral voriconazole, topical natamycin, and topical and intracameral amphotericin B...

Acanthamoeba keratitis (AK) is a sight-threatening infectious disease. Resistance of the cystic form of the protozoan to biocides and the potential toxicity of chemical compounds to corneal cells are the main concerns related to long-term treatment with the clinically available ophthalmic drugs. Currently, a limited number of recognized antimicrobial agents are available to treat ocular amoebic infections. Topical application of biguanide and diamidine antiseptic solutions is the first-line therapy. We consider the current challenges when treating AK and review the chemical properties, toxicities, and mechanisms of action of the available biocides...

BACKGROUND: Pyoderma gangrenosum (PG) is a rare, ulcerative cutaneous disorder. Ophthalmic involvement in PG is atypical, but can have devastating consequences. OBJECTIVE: We sought to characterize ocular PG to allow for earlier diagnosis and therapy. To our knowledge, this is the first systematic review summarizing this clinical variant. METHODS: A systematic review was conducted using PubMed and Web of Science. Data were extracted and studies were qualitatively assessed and analyzed...

We investigated the clinical and mycological characteristics of four cases of mycotic keratitis caused by Aspergillus flavus that occurred from July 2014 to May 2015 at Çukurova University Hospital, Adana, Turkey. In a 10-month period, a total of 64 corneal smear/scrapings were examined from patients with suspected mycotic keratitis. Fungal cultures were positive in six of these patients, indicating a 9.4% incidence of mycotic keratitis in this region, including four cases of A. flavus and two cases of Fusarium spp...

REVIEW
Nathan Efron
Eye-care practitioners typically associate ocular inflammation during contact lens wear with serious complications such as microbial keratitis; however, more subtle mechanisms may be at play. This paper tests the notion that contact lens wear is intrinsically inflammatory by exploring whether uncomplicated contact lens wear meets the classical, clinical definition of inflammation - rubor (redness), calor (heat), tumor (swelling), dolor (pain) and functio laesa (loss of function) - as well as the contemporary, sub-clinical definition of inflammation (cellular and biochemical reactions)...

BACKGROUND: Leprosy is a chronic granulomatous infection that affects skin and peripheral nerves. Its prevalence has declined, but is still observed mainly in poor rural areas. CASE REPORT: A male city dweller with photophobia and chronic dermatosis in the face: nodular and erythematous lesions, pustules, keratitis and entropion, partial eyebrows loss, and edema on eyelids, chin, and nose bridge. The rest of the body had no lesion or lymphadenopathy. Biopsy revealed Langhans giant cell proliferation in the superficial dermis without epidermal atrophy...

BACKGROUND: The repertoire of free-living protozoa in contact lens solutions is poorly known despite the fact that such protozoa may act as direct pathogens and may harbor intra-cellular pathogens. METHODS: Between 2009 and 2014, the contact lens solutions collected from patients presenting at our Ophthalmology Department for clinically suspected keratitis, were cultured on non-nutrient agar examined by microscope for the presence of free-living protozoa. All protozoa were identified by 18S rRNA gene sequencing...

Purpose: High mobility group box 1 (HMGB1) contributes to poor disease outcome in Pseudomonas aeruginosa keratitis. This study tests the prophylactic effect of treatment with HMGB1 inhibitors, glycyrrhizin (GLY) and its derivative, carbenoxolone (CBX), for Pseudomonas keratitis. Methods: We treated C57BL/6 (B6) mice subconjunctivally with GLY or CBX, infected with a noncytotoxic clinical isolate (KEI 1025) or a cytotoxic strain (ATCC 19660) of P. aeruginosa, and injected intraperitoneally with either agent...
