1. REFLECT - Before reading this module, consider the following: Will this clinical area be relevant to my practice. 2. IDENTIFY - If the answer is no, I may still be interested in the area but the article may not contribute towards my continuing professional development (CPD). If the answer is yes, I should identify any knowledge gaps in the clinical area. 3. PLAN - If I have identified a knowledge gap

- will this article satisfy those needs - or will more reading be required? 4. EVALUATE - Did this article meet my learning needs - and how has my practise changed as a result? Have I identified further learning needs?

Red eye is a presenting complaint of both serious and non-serious causes of eye pathology and is one of the most common eye problems that pharmacists deal with in over the counter consultations. Due to the delicate nature of the eye and the possibility of serious complications, it is important to refer patients where there is any doubt as to the nature of the disorder. Red eye is a clinical sign caused by the dilation of the superficial ocular blood vessels, in the eye. Dilation of these vessels can result from infection, allergy, inflammation or elevated intraocular pressure. Redness (hyperaemia) of the eye can occur alone or present with accompanying symptoms of pain, discomfort, discharge and loss of visual acuity. The most common cause of red eye is conjunctivitis. There are a number of other causes of red eye, which we will explore in this article. The aim of this clinical feature is to discuss distinctive signs and symptoms of common red eye conditions that present in a pharmacy setting and the rationale for their management. It can also be used as a reference and staff training guide for OTC staff. Pharmacists and OTC staff need to take a comprehensive optical and medical history to ensure that the patients are referred appropriately while others are treated with over the counter (OTC) medication. 1. BLEPHARITIS It is one of the most common eye problems. It is a chronic inflammation of the eyelids, which can cause red or watery eyes, discomfort and

an oily or flaky discharge around the lashes. The oil glands in the eyelid may become blocked or infected (Meibomian Gland Dysfunction) which can give rise to similar symptoms. Patients complain of a gritty, itchy, uncomfortable red eye that is worse upon waking. Patients should be advised that they should wash the eyelids with specialised blepharitis lotions/gels (e.g. Blephasol®) or eyelid scrub wipes (e.g. Ocusoft or Blephasol® wipes). Non-irritating baby shampoos are recommended as lid cleansers in the past, however, some ophthalmologists advise against their use due to SLS (Sodium Lauryl Sulphate) allergy and the drying effect on the eye. Resting a warm compress such as a warm facecloth over the affected eye may soften and release any gland blockages. Commercial Warm compress products (e.g. Eyebag®) can also be used. While patients should experience some relief within one month the treatment generally needs to be continued for a few months. Ocular lubricants can be helpful to relieve the symptoms of associated dry eye. Key counselling point – Patients need to be reminded that this is a chronic eye condition and that frequent cleaning of the edge of the eyelids and warm compresses need to be continued daily for several months. 2. CONJUNCTIVITIS The majority of patients presenting to the pharmacist with red eye will have some form of conjunctivitis. The conjunctiva is the membrane covering the eye (except for the cornea) and the inner surface of the eyelids. Conjunctivitis can result from either an infection (viral or bacterial) or an allergen. Conjunctivitis is subdivided into three types- bacterial, viral and allergic conjunctivitis. Staphylococcus or Haemophilus bacteria most frequently cause bacterial conjunctivitis. The adenovirus is most commonly implicated in causing isolated viral conjunctivitis. Pollen is the usual cause of seasonal allergic conjunctivitis. Non-allergic conjunctival irritation can result from foreign bodies - wind, dust, smoke, fumes, chemical vapours and other types of air pollution. Each of the three types of conjunctivitis presents with

60 Second Summary Red eye is a presenting complaint of both serious and non-serious causes of eye pathology and is one of the most common eye problems that pharmacists deal with in over the counter consultations. Due to the delicate nature of the eye and the possibility of serious complications, it is important to refer patients where there is any doubt as to the nature of the disorder. The aim of this clinical feature is to discuss distinctive signs and symptoms of common red eye conditions that present in a pharmacy setting and the rationale for their management. The majority of patients presenting to the pharmacist with red eye will have some form of conjunctivitis. The conjunctiva is the membrane covering the eye (except for the cornea) and the inner surface of the eyelids. The main treatment for dry eyes is artificial tears which are available OTC. There are a number of products on the market with good ocular surface wetting properties which increase the moisture and lipid content of the ocular surface. Infection with herpes simplex is extremely common — about 90 per cent of the population carry herpes simplex antibodies. Primary infections with herpes simplex usually occur between the ages of six months and five years. This may involve typical symptoms of a viral illness (eg, swollen lymph glands, malaise, sore throat) or the infection may be subclinical. Giving the correct advice depends on the pharmacist and pharmacy staff being able to determine the most likely condition(s) which involves asking the right questions. Careful history taking and an awareness of signs and symptoms that are triggers for referral can ensure pharmacists safely and effectively manage red eye ophthalmic conditions.

HSV virus typically affects the eyelids, conjunctiva and cornea. If the cornea is infected, the active disease is called herpes keratitis. On optical examination, the infection typically presents as a central ocular ulcer (dendritic lesion). The patient needs to be referred immediately. For a corneal dendritic ulcer, aciclovir (Zovirax®) eye ointment applied five times a day to the affected eye is usually effective. A 1cm line of ointment should be placed inside the lower conjunctival sac and the eye kept closed for 30 seconds after application. Two weeks’ treatment should be sufficient. In some cases oral treatment may be required. Patients who suffer severe or recurrent infections are at higher risk of corneal scarring.

There can often be an underlying systemic autoimmune condition such as rheumatoid arthritis. This condition should be immediately referred as it may be part of systemic autoimmune response. Key Counselling Point - Advise the patient to seek medical treatment urgently. 11. STYES A stye (hordeolum) is usually caused by Stephylococcus Aureus infection of the eyelash follicle and in severe cases the infection can be associated with the infection spreading to the gland of Zeis (sebaceous gland) or the gland of Moll (sweat gland). It presents as a red swelling on the eyelid margin and in severe cases the eyelid can become swollen. As it is bacterial in origin, yellow discharge (pus) can be seen and sometimes it can be painful. Without treatment a stye is usually self-limiting and will usually resolve within 7 to 14 days. Products containing Propamidine (Brolene® and Golden Eye® eye ointment) and warm compresses (Eyebag®) may be helpful. If the infection spreads and the eyelid swells, the patient will need to be referred as a topical or systemic antibiotic may be necessary. In certain cases, eyelashes are removed to release the infection and the stye resolves. Key Counselling Point - Advise patients that eye ointments are more effective than eye drops for the treatment of styes. Remind patients that eye ointments may blur vision and not to drive after applying eye ointments. 12.
