Viral conjunctivitis is a self-limiting condition, and the commonest cause of a red eye presentation in general practice. It is typically caused by adenovirus. Other, less common viruses include herpes simplex, herpes zoster, enterovirus, and coxsackie virus.

Herpes Zoster Ophthalmicus (HZO) is defined by involvement of the ophthalmic branch of the trigeminal nerve (CN V1). This branch supplies the forehead, the anterior scalp, the side and tip of the nose, ethmoidal sinuses, and importantly, all structures within the globe, including the retina and optic nerve. Zoster involving the maxillary division of the trigeminal nerve (CN V2) is not globe threatening, and does not require referral to an ophthalmologist.

Since opening in November 2014, Dr Dana Robaei and the team at Forest Eye Surgery have been working closely with local optometrists and general practitioners, offering regular educational seminars to assist them with the accurate and timely diagnosis of patients in the Northern beaches and North Shore areas.
