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.

Update and projections for New Zealand's ophthalmology workforce.

Aim: The aim of this study was to update and project the growth of ophthalmologists in New Zealand. This will help decision makers better understand the current ophthalmologist workforce and make appropriate resource allocations.

Method: Supply and demographics of ophthalmologists in New Zealand were obtained from the Medical Council of New Zealand, Health Workforce New Zealand and Health New Zealand - Te Whatu Ora.

Intereye Asymmetry as a Predictor of Progression in Patients With Untreated Keratoconus: Findings From a Longitudinal Study.

Purpose: The purpose of this study was to evaluate interocular predictors of progression in patients with untreated keratoconus.

Methods: This is a multicenter longitudinal observational study with real-world data collected through the Save Sight Keratoconus Registry. Patients between the period of June 2000 and September 2022 were included in this study.

Automatic Refractive Error Estimation Using Deep Learning-Based Analysis of Red Reflex Images.

: We evaluate how a deep learning model can be applied to extract refractive error metrics from pupillary red reflex images taken by a low-cost handheld fundus camera. This could potentially provide a rapid and economical vision-screening method, allowing for early intervention to prevent myopic progression and reduce the socioeconomic burden associated with vision impairment in the later stages of life. : Infrared and color images of pupillary crescents were extracted from eccentric photorefraction images of participants from Choithram Hospital in India and Dargaville Medical Center in New Zealand.

Patch endothelial keratoplasty for corneal perforations secondary to ocular surface disease: case series.

Background: Corneal perforation is an ophthalmic emergency. The conventional management of corneal perforation can be associated with severe complications especially in patients with ocular surface disease. Endothelial keratoplasty has been suggested as an alternative surgical technique for the management of corneal perforations.

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.

Photorefraction Screening Plus Atropine Treatment for Myopia is Cost-Effective: A Proof-of-Concept Markov Analysis.

Purpose: The prevalence of myopia is increasing globally, putting individuals at risk of myopia-associated visual impairment. Low-dose atropine eye drops have been found to safely reduce the risk of progression from myopia to higher levels of myopia and pathological states. In New Zealand, school children have an eye check at age 11.

A new approach to non-mydriatic portable fundus imaging.

Introduction: The present study proposes a new hand-held non-mydriatic fundus camera for retinal imaging. The goal is to design a fundus camera which is equally effective in both clinical and telemedicine scenarios.

Areas Covered: A new retinal illumination approach is proposed to address the main dilemma of the optical design, i.

A Systematic Review of Current Teleophthalmology Services in New Zealand Compared to the Four Comparable Countries of the United Kingdom, Australia, United States of America (USA) and Canada.

Background: Over 700,000 New Zealanders (NZ), particularly elderly and Māori, live without timely access to specialist ophthalmology services. Teleophthalmology is a widely recognised tool that can assist in overcoming resource and distance barriers. Teleophthalmology gained unprecedented traction in NZ during the COVID-19 pandemic and subsequent lockdown.

On the use of a new monocular-indirect ophthalmoscope for retinal photography in a primary care setting.

Aim: There is consensus among general practitioners regarding the difficulty of direct ophthalmoscopy. Hence, there is increasing interest in smartphone-based ophthalmoscopes; the New Zealand-made oDocs Nun ophthalmoscope is one such device, released in November 2018. This study aims to subjectively assess the quality of the images captured with it in order to determine the feasibility of its use in a primary care setting.

The Detection of Spontaneous Venous Pulsation with Smartphone Video Ophthalmoscopy.

Purpose: Spontaneous venous pulsation (SVP) has a high negative predictive value for raised intracranial pressure and is a useful sign when assessing patients with headache. The objective was to determine if smartphone-based video ophthalmoscopy can detect SVP.

Patients And Methods: In total 233 patients and 291 eyes were recruited from the Dunedin Hospital eye clinic from July to November 2018.

Development of an artificial intelligence system to classify pathology and clinical features on retinal fundus images.

Importance: Artificial intelligence (AI) algorithms are under development for use in diabetic retinopathy photo screening pathways. To be clinically acceptable, such systems must also be able to classify other fundus abnormalities and clinical features at the point of care.

Background: We aimed to develop an AI system that can detect several fundus pathologies and report relevant clinical features.

Diabetic retinopathy screening using deep neural network.

Importance: There is a burgeoning interest in the use of deep neural network in diabetic retinal screening.

Background: To determine whether a deep neural network could satisfactorily detect diabetic retinopathy that requires referral to an ophthalmologist from a local diabetic retinal screening programme and an international database.

Design: Retrospective audit.

Safety of iPhone retinal photography.

Background: With the advancement in mobile technology, smartphone retinal photography is becoming a popular practice. However, there is limited information about the safety of the latest smartphones used for retinal photography.

Aims: This study aims to determine the photobiological risk of iPhone 6 and iPhone 6 plus when used in conjunction with a 20Diopter condensing lens for retinal photography.

Brain mushroom: A case of osteolytic intraosseous meningioma with transcalvaria herniation.

A 61-year-old male presented with primary intraosseous osteolytic meningioma and transcalvaria herniation. This is an extremely rare condition with only 16 case reports of osteolytic intraosseous meningioma. This case is unique because it was accompanied by a transcalvaria herniation.
