Glaucoma Calc can be used to estimate the risk of a patient with ocular hypertension developing glaucoma within 5 years. The ONLY calculator that lets you enter your field measurements YOUR way. Easy, single-screen interface, for fast decision-making in a busy practice. The original OHTS calculator is still the best. Now with easy entry for both eyes, reducing the workload on your brain. It uses the same calculation data as some other online calculators and electronic single-purpose calculators. However, being on your iPhone means you always have it available at all times. It also has the benefit of having full support for all three major perimeters: Humphrey, Medmont and Octopus. No manual conversion is required. And, being an iPhone application, its really simple to use, everything happens on just one screen, enter your five parameters (Age, IOP, C/D ratio, CCT and PSD/PD/LV) and the glaucoma risk is displayed. Now includes an Apple Watch app that lets you calculate your patients' glaucoma risk without leaving your wrist! The Apple Watch app works independently of the iPhone app, you don't even need your iPhone with you for the app to work. A Complication is included to give you quick access to the last calculated risk value, and to allow one-touch access to the app if you are using it regularly. Please remember that this application is purely an aid, and is not a replacement for clinical judgement.

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?
