Background: Paediatric periorbital cellulitis, a common eye condition, typically requires inpatient admission for intravenous antibiotics due to concerns about orbital spread. This study aimed to assess the safety and effectiveness of ambulatory management for children with moderate periorbital cellulitis.

Methods: Over a 24-month period, we prospectively enrolled 84 children aged 1 to 16 years who presented with moderate periorbital cellulitis to the emergency department.

Objective: In this article we present a conceptual framework for enhancing effective healthcare communication in Australia and Aotearoa New Zealand.

Methods: Through an iterative, deliberative dialogue approach, we, as experts from a variety of health professions and academic disciplines, worked together to identify core values and considerations for healthcare communication across numerous health professions and disciplines and within research, teaching, policy, and practice contexts.

Results: The framework developed includes five core values at its centre: equitable, inclusive, evidence-based, collaborative, reflective.

Background: Paediatric periorbital cellulitis is a common eye condition and warrants prompt management for the prevention of complications. International consensus on the approach to optimal management of children with mild periorbital cellulitis including ambulatory management is lacking. We aimed to prospectively investigate the safety and effectiveness of ambulatory management of children with mild periorbital cellulitis.

Objective: Irritable bowel syndrome (IBS) is a chronic disorder associated with an abnormal gastrointestinal microbiome. Microbiome-host interactions are known to influence organ function including in the central nervous system; thus, we sought to identify whether IBS may be a risk factor for the development of glaucoma.

Design: Two prospective cohort studies.

Purpose: To assess which factors in the lives and disease of patients with glaucoma affect their adherence to topical glaucoma therapy and the quantitative significance of this effect. To assess qualitatively the most influential barriers to adherence from the perspective of the patient.

Design: Multicenter, prospective, cross-sectional pilot study.

The microbiome located within a given host and its organs forms a holobiont, an intimate functional entity with evolutionarily designed interactions to support nutritional intake and reproduction. Thus, all organs in a holobiont respond to changes within the microbiome. The development and function of the central nervous system and its homeostatic mechanisms are no exception and are also subject to regulation by the gut microbiome.

Purpose: Tooth loss or periodontal disease is associated with systemic endothelial dysfunction, which has been implicated in primary open-angle glaucoma (POAG). The relationship between oral health and POAG has received limited attention. Thus, we evaluated the association between oral health history and risk of POAG and POAG subtypes.

Purpose: To determine the incidence of endophthalmitis in a large clinical series using aqueous chlorhexidine for antisepsis before intravitreal injection and to review the ophthalmic literature regarding chlorhexidine efficacy and safety.

Design: Multicenter retrospective case series.

Participants: All patients receiving intravitreal injections from 7 retinal specialists.

The study aims to validate mouse retinal explants for use as an efficient tool to investigate neuroprotective therapies for treatment in diseases such as glaucoma. Eyes from C57BL/6 mice were enucleated immediately post-mortem to make two retinal explants per eye. Explants were cultured at an air/medium interface on membrane inserts for 7 days ex-vivo.

Purpose: To evaluate visual outcomes after femtosecond laser-assisted cataract surgery (LCS) with phacoemulsification cataract surgery (PCS).

Design: Prospective, multicenter, comparative case series.

Participants: Consecutive patients undergoing femtosecond LCS or PCS with intraocular lens insertion.

Detachment of a hydrodissection cannula during a phacoemulsification procedure appeared to produce no adverse sequelae during surgery. Day 1 postoperatively, two nonpenetrating hemorrhagic retinal lesions were identified; there was no evidence of posterior capsular perforation. Day 6 postoperatively, the pupil was temporally peaked by a fine vitreous strand running to the main-port incision in the superotemporal cornea.

Objective: To compare the incidence of anterior capsular tears after femtosecond laser-assisted cataract surgery (FLACS) versus phacoemulsification cataract surgery (PCS) and to assess the ultrastructural features of anterior capsulotomy specimens (FLACS and PCS) using electron microscopy.

Design: Prospective, multicenter, comparative cohort case series.

Participants: Consecutive patients undergoing FLACS or PCS.
