The Persistent Dilemma of Microbial Keratitis: Global Burden, Diagnosis, and Antimicrobial Resistance.

Department of Ophthalmology, Massachusetts Eye and Ear, Harvard Medical School, Boston, Massachusetts, USA; Infectious Disease Institute, Massachusetts Eye and Ear, Harvard Medical School, Boston, Massachusetts, USA. Electronic address:

Microbial keratitis (MK) is a potentially blinding condition which must be treated emergently to preserve vision. Although long recognized as a significant cause of corneal blindness, our understanding of its true global scale, associated burden of disease, and etiological patterns remains somewhat limited. Current epidemiological data suggests that MK may be epidemic in parts of the world--particularly within South, South-East and East Asia--and may exceed two million cases per year world-wide.

Although there have been few reports of opportunistic infections (superficial and systemic) caused by coelomycetous fungi, they are becoming more frequent. Neocucurbitaria keratinophila (formerly Pyrenochaeta keratinophila), characterized by producing pycnidial conidiomata and small hyaline conidia, seems to be an emergent opportunistic pathogen in Spain. Since this fungus was first reported from human keratitis, eight strains have been isolates from clinical cases in Spain. Read More

PLoS One 2018 28;13(11):e0208163. Epub 2018 Nov 28.

Department of Ophthalmology, Renmin Hospital of Wuhan University, Wuhan, Hubei Province, China.

To investigate the clinical characteristics, treatment, risk factors of occurrence and graft transparency of corneal epithelial defects after penetrating keratoplasty in patients with infectious keratitis. 594 patients (594 eyes) with infectious keratitis treated by penetrating keratoplasty at Shandong Eye Institute were reviewed retrospectively between January 2008 and January 2018. We investigated the demographic data, diameter and sources of graft, onset time, location, scope, time of healing and treatment of epithelial defects, as well as other postoperative complications and graft clarity.

Challenges in the Polyene- and Azole-Based Pharmacotherapy of Ocular Fungal Infections.

J Ocul Pharmacol Ther 2019 Jan/Feb;35(1):6-22. Epub 2018 Nov 8.

1 Department of Pharmaceutics and Drug Delivery, School of Pharmacy, University of Mississippi, Oxford, Mississippi.

Polyenes and azoles constitute 2 major drug classes in the antifungal armamentarium used to treat fungal infections of the eye such as fungal keratitis, endophthalmitis, conjunctivitis, and blepharitis. These classes of drugs have come to occupy an important niche in ophthalmic antifungal therapy due to their broad spectrum of activity against a variety of filamentous and yeast-like fungi. Natamycin suspension (Natacyn), a polyene antifungal drug, is currently the only US FDA-approved formulation for treating ophthalmic fungal infections, whereas the other polyene and azole antifungals such as amphotericin B, fluconazole, itraconazole, ketoconazole, miconazole, voriconazole, and posaconazole are routinely used off-label in the clinical setting.

Clinical management of herpes simplex virus infections: past, present, and future.

F1000Res 2018 31;7. Epub 2018 Oct 31.

Department of Pathobiology, School of Veterinary Medicine, Louisiana State University, Baton Rouge, LA, 70803, USA.

Infection with herpes simplex virus (HSV) types 1 and 2 is ubiquitous in the human population. Most commonly, virus replication is limited to the epithelia and establishes latency in enervating sensory neurons, reactivating periodically to produce localized recurrent lesions. However, these viruses can also cause severe disease such as recurrent keratitis leading potentially to blindness, as well as encephalitis, and systemic disease in neonates and immunocompromised patients.

Corneal targeted Sertaconazole nitrate loaded cubosomes: Preparation, statistical optimization, in vitro characterization, ex vivo permeation and in vivo studies.

Int J Pharm 2018 Dec 26;553(1-2):386-397. Epub 2018 Oct 26.

Department of Pharmaceutics and Industrial Pharmacy, Faculty of Pharmacy Cairo University, Kasr El Einy St., 11562 Cairo, Egypt.

Sertaconazole nitrate (STZ) is a poorly soluble antifungal drug commonly used for treating fungal skin infections. Introducing it as a new treatment option for the management of fungal keratitis, requires the development of a delivery system capable of targeting the infected cornea with an adequate STZ concentration. Hence, Sertaconazole nitrate loaded cubosomes (STZ-CUBs) were prepared, characterized and optimized based on a 3 central composite face-centred design. Read More

Box Behnken design of siRNA-loaded liposomes for the treatment of a murine model of ocular keratitis caused by Acanthamoeba.

Colloids Surf B Biointerfaces 2019 Jan 18;173:725-732. Epub 2018 Oct 18.

Graduate Program in Pharmaceutical Sciences, Faculty of Pharmacy, Federal University of Rio Grande do Sul, Porto Alegre, Brazil. Electronic address:

Acanthamoeba keratitis is an ophthalmic disease with no specific treatment that specially affects contact lens users. The silencing of serine phosphatase (SP) and glycogen phosphorylase (GP) proteins produced by Acanthamoeba has been shown to significantly reduce the cytopathic effect, although no vehicle was proposed yet to deliver the siRNA sequences to the trophozoites. In this study, PEGylated cationic liposomes were proposed and optimized using Box-Behnken design. Read More
