Eye Emergency Manual vs OSLA

This app is designed for use by all medical, nursing and allied health clinicians in Emergency Departments across New South Wales. It provides a quick and simple guide to recognising important signs and symptoms, and management of common eye emergencies. The app will also be of assistance in triaging patients to appropriate care within the health system. The content within this app was developed by ophthalmic and emergency clinicians of the NSW Agency for Clinical Innovation (ACI). These guidelines have not undergone a formal process of evidence based clinical practice guideline development however they are the result of consensus opinion determined by the expert clinician working group. They are not a definitive statement on the correct procedures rather they constitute a general guide to be followed subject to the clinician’s judgment in each case. The consensus opinion provided is based on the best information available at the time of writing. To help with ease of use, this manual has a high graphic content, and is subdivided into anatomy, basic ophthalmic workup (history, examination, diagnostic techniques and treatment), and management of common eye presentations. Each of the presenting conditions is subdivided into the following sections: • Immediate action (if any) • History • Examination • Treatment • Follow-up - When to refer?

OSLA measures the surface area of ocular surface lesions from a photo. Capture a close-up of the eye, mark the iris as an 11.5 mm reference, trace the lesion, and OSLA reports the area in square millimetres. Built for eye care clinicians and researchers who need a consistent, repeatable way to document lesion size in clinic or in the field. How it works: - Capture with the guided camera (near focus lock, flash at capture) or pick an existing photo - Draw around the iris. Its 11.5 mm average diameter sets the real-world scale - Trace the lesion freehand, or tap point by point - Read the area in square millimetres, with maximum and minimum dimensions The saved photo includes the annotations and a small measurement card, so the result can go straight into your records. Everything runs on the device. No account, no upload, no tracking. Photos stay on your phone unless you choose to share them. OSLA is useful for documenting and monitoring conditions such as ocular surface squamous neoplasia, pterygium and conjunctival naevi. It is a documentation aid for clinicians, not a diagnostic device, and it does not replace clinical judgement.
