Generalizability of Deep Neural Networks for Vertical Cup-to-Disc Ratio Estimation in Ultra-Widefield and Smartphone-Based Fundus Images.

Purpose: To develop and validate a deep learning system (DLS) for estimation of vertical cup-to-disc ratio (vCDR) in ultra-widefield (UWF) and smartphone-based fundus images.

Methods: A DLS consisting of two sequential convolutional neural networks (CNNs) to delineate optic disc (OD) and optic cup (OC) boundaries was developed using 800 standard fundus images from the public REFUGE data set. The CNNs were tested on 400 test images from the REFUGE data set and 296 UWF and 300 smartphone-based images from a teleophthalmology clinic.

Impact of Community Eye Clinics (CEC) on Specialist Eye Clinic Referrals.

Purpose: Community Eye Clinics (CEC) increase accessibility of specialist ophthalmic services in the community, reducing demand for tertiary eye services. This paper aims to evaluate the impact of CEC on first-visit referrals from Hougang Polyclinic (HOU) to Tan Tock Seng Hospital Ophthalmology Specialist Outpatient Clinic (SOC).

Methods: A retrospective analysis was performed on first-visit referrals from Hougang Polyclinic (HOU) to Tan Tock Seng Hospital Ophthalmology Specialist Outpatient Clinic (SOC) over a similar 3-months period before and after the introduction of CEC in August 2018 (1 January to 31 March in 2018 and 2019, respectively).

BISPHOSPHONATE-INDUCED BILATERAL ANTERIOR UVEITIS AND CHOROIDAL EFFUSIONS WITH SECONDARY ANGLE CLOSURE.

Purpose: To report a case of bisphosphonate-induced bilateral anterior uveitis and choroidal effusions with secondary angle closure in a 64-year-old female patient.

Methods: Observational case report.

Results: A 64-year-old woman with history of scleroderma and antiphospholipid syndrome, presented with bilateral painless blurring of vision after commencement of alendronate.
