Orbicularis Oculi Transpalpebral Pedicle Flap for the Repair of Laminar Resorption Associated With Osteo-Odonto-Keratoprosthesis.

Osteo-odonto-keratoprosthesis (OOKP) is a surgical procedure reserved for severe end-stage corneal blindness with a dry, keratinized ocular surface. Late resorption of bone has been described as a complication of this procedure. We present a novel surgical technique to repair laminar resorption associated with OOKP using transpalpebral split-pedicle orbicularis oculi flaps.

A case for the use of chemotherapy in hereditary mitochondrial optic neuropathies: Successful administration of cisplatin/etoposide in a male patient with testicular seminoma and Leber's hereditary optic neuropathy.

We report on the successful use of chemotherapy for treatment of stage 2B testicular seminoma in a carrier of the Leber's hereditary optic neuropathy 11778 mitochondrial mutation. Neurotoxic chemotherapy may not prompt disease conversion.

Comparison of the structural integrity and quality of corneal endothelium stored in organ culture storage medium versus Eusol-C.

In this experimental study, we compared the structural integrity and cell quality of corneal endothelium stored in organ culture medium (OCS) and Eusol-C. The experiment included rabbit and human cornea experiments in vitro. Thirty rabbit corneas and thirty-two human corneas were collected and divided into two groups.

Zooming in on the intracellular microbiome composition of bacterivorous isolates.

, a free-living amoeba in water and soil, is an emerging pathogen causing severe eye infection known as keratitis. In its natural environment, performs a dual function as an environmental heterotrophic predator and host for a range of microorganisms that resist digestion. Our objective was to characterize the intracellular microorganisms of phylogenetically distinct spp.

Managing the apparently blind child presenting in the first year of life: A review.

Severe vision impairment and blindness in childhood have a significant health burden on the child, family and society. This review article seeks to provide a structured framework for managing the apparently blind child presenting in the first year of life, starting from a comprehensive history and examination. Different investigation modalities and the increasingly important role of genetics will also be described, in addition to common causes of severe vision impairment.

The role of naturally acquired intracellular Pseudomonas aeruginosa in the development of Acanthamoeba keratitis in an animal model.

Background: Acanthamoeba is an environmental host for various microorganisms. Acanthamoeba is also becoming an increasingly important pathogen as a cause of keratitis. In Acanthamoeba keratitis (AK), coinfections involving pathogenic bacteria have been reported, potentially attributed to the carriage of microbes by Acanthamoeba.

Burn related globe and adnexal trauma at trauma centres.

Introduction: Prompt management of burn-related globe trauma can prevent long term complications. Delays in diagnosis may occur when globe trauma is associated with life-threatening injuries. We aimed to improve the understanding of the epidemiology, acute assessment and management of burns-related globe and adnexal trauma admitted to two trauma centres in Sydney, Australia.

Globe trauma associated with falls at Australian tertiary centres.

Objective: Falls frequently cause globe and adnexal trauma, particularly in the elderly. The morbidity decreases confidence, independence and quality of life. We aimed to improve the understanding of fall-related globe and adnexal trauma and the involvement of ophthalmology at two tertiary trauma centres.

Globe and adnexal trauma at Australian trauma centres.

Introduction: In multisystem trauma, the assessment and management of globe and adnexal trauma is often complex. Ophthalmology input may assist managing such patients. To understand the role of ophthalmology in tertiary trauma centres we report on the management of globe and adnexal trauma at two tertiary trauma centres in Sydney, Australia.

Case Series of Rare Fungal Keratitides: Experiences from a Quaternary Eye Hospital in Sydney, Australia.

The present article reports on the management of six different and rare cases of fungal keratitides, two of which have never been documented in previous literature. This is a case series of six patients with rare fungal keratitides managed at a quaternary eye referral unit, Sydney Eye Hospital, Australia over a period of 7 months (May to December, 2022). The order of occurrence of fungi isolated was , , spp.

Spectrum of ocular disease in children aged between 0 and 3 years at an Australian paediatric tertiary hospital.

Background: Childhood ocular disease can be a significant health burden to the child, family and society. Previous studies have examined the spectrum of paediatric ocular disease presenting to tertiary hospitals; however, these studies have broader age ranges, smaller sample sizes, and are largely based in developing countries. This study aims to assess the spectrum of ocular disease in the first 3 years of life presenting to the eye department of an Australian tertiary paediatric hospital.

Epidemiology and Economic Cost Analysis of Microbial Keratitis from a Tertiary Referral Hospital in Australia.

Microbial keratitis is the most common cause of infective vision loss. The causative organism varies by region, and most cases require intensive antimicrobial therapy. The purpose of this study was to analyse the causative organisms of microbial keratitis, its presentation and economic burden from a tertiary referral hospital in Australia.

Acanthamoeba, an environmental phagocyte enhancing survival and transmission of human pathogens.

The opportunistic protist Acanthamoeba, which interacts with other microbes such as bacteria, fungi, and viruses, shows significant similarity in cellular and functional aspects to human macrophages. Intracellular survival of microbes in this microbivorous amoebal host may be a crucial step for initiation of infection in higher eukaryotic cells. Therefore, Acanthamoeba-microbe adaptations are considered an evolutionary model of macrophage-pathogen interactions.

Five-year outcomes of eyes initially enrolled in the 2-year BEVORDEX trial of bevacizumab or dexamethasone implants for diabetic macular oedema.

Background: The BEVORDEX trial compared outcomes of eyes with diabetic macular oedema (DMO) randomised to receive either intravitreal dexamethasone (DEX-) implant or bevacizumab over 2 years. We assessed long-term efficacy and safety outcomes 5 years from enrolment.

Methods: Patients received standard clinical care after they finished the study.

Intensive care nurses' experiences with the new electronic medication administration record.

Aim: To explore the experiences of Registered Nurses who administered medications to patients using the electronic medication administration record (eMAR) in Electronic Record for Intensive Care (eRIC) at one adult intensive care unit (ICU) in NSW, Australia.

Design: The study research design used a qualitative descriptive exploratory approach that took place in two stages.

Methods: Five participants attended one focus group followed by the observation of each participant as medications were administered to their assigned patient using the eMAR in eRIC.

Infection After Endoscopic Dacryocystorhinostomy: Incidence and Implications.

Background: Endoscopic dacryocystorhinostomy (EN-DCR) is an increasingly common procedure performed by otolaryngologists. While EN-DCR has a high rate of success at relieving blockage of the lacrimal system, little is known regarding associated postoperative infection (POI) rates and risk factors.

Objective: The purpose of this study was to identify factors associated with the occurrence of postoperative orbital and rhinologic infection in a large cohort of patients undergoing EN-DCR.

Frontal sinus fractures and cerebrospinal fluid leaks: a change in surgical paradigm.

Purpose Of Review: Traditionally, frontal sinus trauma has been treated using open incisions to access the anterior and/or posterior table. Mounting evidence indicates frontal sinus trauma can be managed using an endoscopic endonasal approach (EEA) with less morbidity. Such an approach permits preservation of a functional sinus and less reliance on computed tomography for postoperative follow up.
