Glaucoma is a common eye condition which involves optic nerve damage, resulting in progressive peripheral vision loss. It is most commonly caused by raised intraocular pressure (IOP), therefore most medical and surgical treatments aim to lower the IOP by either reducing production or increasing drainage of aqueous humour in the anterior chamber of the eye. It is important to note that glaucoma management is centred around prevention of further vision loss rather than restoration of vision that has already been lost, and thus early diagnosis and management are paramount.

Sympathetic ophthalmia (SO) is a bilateral granulomatous uveitis following penetrating ocular trauma or surgery. It is a rare but important cause of irreversible visual loss in trauma. Early identification and intervention is therefore vital in mitigating the long term effects of this potentially sight threatening disease.

There comes a daunting time in every foundation doctor’s life when they are expected to make a life-changing decision about applying to a specialty training programme. A simple click of a button can open doors, paving the way for a whole new journey of self-learning and clinical challenges. Choosing a specialty requires careful consideration and is a task that many struggle with. A number of foundation trainees are uncertain about their career choice between medical and surgical sub-specialities due to limited exposure, lack of insight into professional satisfaction and sense of career achievement. Additionally, there is fierce competition for entry into most specialist training programmes. Ophthalmology is unique with regards to its immensely intricate practical skills but also provides scope for diagnosis, treatment and prevention of diseases - arousing the “medical” mind.

Direct ophthalmoscopy – salvageable skill or pointless pursuit?

The direct ophthalmoscope was invented in 1851 and ophthalmologists were first able to visualize retinal detachment through it in 1853. Subsequently, the first viewings of central retinal artery occlusion and papilloedema were obtained in 1855 and 1860, respectively. Despite being around for more than a century, today’s medical students still lack the confidence and competence to perform it well. Concerningly, this lack of confidence is not exclusive to medical students. Amongst junior doctors, only one in five foundation year doctors felt confident identifying papilloedema by the end of foundation year. Amongst more senior doctors, up to 43% of General Practitioners admitted to lacking confidence in performing direct ophthalmoscopy.

Acanthamoeba keratitis involves inflammation of the cornea, the thin protective transparent layer at the front of the eye, caused by the protozoa Acanthamoeba. It is rare but can be sight-threatening with an annual incidence of 1.4 per million per annum, and typically affects contact lens wearers (1).

Retinoblastoma is the most common childhood intraocular cancer. It originates from a mutation of the retinoblastoma (RB1) gene, a tumour-suppressor gene. Infants are usually diagnosed through an incidental finding of leukocoria. The disease is classified by size, location and number of tumours and it is used to determine treatment. Management includes surgery, radiotherapy, photocoagulation and chemotherapy. Early diagnosis and treatment is key to preserving vision and therefore a thorough understanding of the condition is important.

Bell’s Palsy is a unilateral lower motor neuron facial nerve paralysis of unknown cause. It is the most common cause of acute unilateral facial paralysis and a condition many medical practitioners will encounter throughout their working career (1). With respect to Ophthalmology, paralysis of the orbicularis oculi exposes the eye to significant pathology which will usually require Ophthalmic input to manage and reduce the risk of adverse long-term sequelae.

Cataract: An Overview

A cataract is the opacification of the lens in the eye. Blindness secondary to cataracts is the leading cause of reversible blindness worldwide. However, this is more prevalent in the developing world due to a lack of access to surgery. In the developed world, surgery to remove a cataract, known as phacoemulsification, is the commonest surgical procedure that is carried out. The UK has an ageing population and therefore the prevalence of age-related cataracts will likely increase. Therefore for ophthalmology trainees in the UK, they must have a baseline knowledge of this condition.

Topical Treatment for Open Angle Glaucoma

Glaucoma refers to a group of conditions that lead to damage of the optic nerve head, typically caused by raised intra-ocular pressure. Primary open angle glaucoma is the commonest glaucoma type in the UK and affects 8% of people at 80 years old. In open angle glaucoma the iridocorneal angle is open but aqueous flow is diminished. As glaucoma progresses, it can lead to peripheral visual field loss. The mainstay of treatment initially is with eye drops with the aim of lowering intraocular pressure. Intraocular pressure is determined by the production, circulation and drainage of aqueous humour and is considered normal if between 11-21mmHg. If treated, glaucoma progression can be delayed and most people will not have severe visual impairment.

Infective conjunctivitis is a common ophthalmic condition encountered in general practice. Topical antibiotics are often routinely prescribed in primary care for this generally self-limiting condition, despite evidence-based guidance consistently recommending otherwise. Injudicious antimicrobial prescribing has important social, economic, and public health consequences. This review discusses the evidence-based management of infective conjunctivitis and the implications of overprescribing antibiotics for this condition in primary care.
