New-Onset Ptosis Initially Diagnosed as Conjunctivitis
Australian Family Physician (AFP), 2015
Key topics: third nerve palsy, intracranial aneurysm, neuro-ophthalmology, ptosis, diplopia
Article Summary: This publication examines the distinction between neurogenic ptosis and inflammatory eyelid swelling, highlighting how potentially life-threatening neurological pathology may initially be mistaken for common ocular surface disease.
The article describes the case of a 66-year-old man initially treated for presumed conjunctivitis who subsequently developed worsening periocular pain, diplopia and near-complete ptosis. Ophthalmic examination demonstrated a pupil-involving third cranial nerve palsy with associated ocular motility abnormalities. Urgent neuroimaging subsequently revealed a posterior communicating artery aneurysm requiring neurosurgical intervention.
The publication reviews the differential diagnosis of third nerve palsy and discusses the importance of pupillary assessment, ocular motility examination and urgent referral in patients presenting with ptosis, diplopia or anisocoria.
A Painful, Red Eye
Australian Family Physician (AFP), 2009

Article Summary: This publication reviews the assessment of the painful red eye and outlines important clinical features that may assist primary care clinicians in distinguishing benign ocular surface irritation from potentially sight-threatening disease.
The article discusses important differential diagnoses including microbial keratitis, herpes simplex keratitis, anterior uveitis, acute angle closure glaucoma and scleritis. Particular emphasis is placed on warning signs requiring urgent ophthalmic referral, including photophobia, reduced vision, corneal opacity and contact lens-associated infection.
The publication additionally discusses the potential risks associated with inappropriate corticosteroid use in undiagnosed corneal disease and reinforces the importance of timely specialist assessment in patients with severe ocular pain or visual disturbance.
Steroid Associated Infective Keratitis
Australian Family Physician (AFP), 2011
Key topics: corticosteroids, microbial keratitis, herpes simplex keratitis, corneal ulceration
Article Summary: This publication examines the complications associated with topical corticosteroid use in patients with undiagnosed infective keratitis.
The article reviews the clinical course of steroid-associated corneal infection and discusses important causes including herpes simplex keratitis and bacterial keratitis. Particular emphasis is placed on the risk of delayed diagnosis, progressive corneal thinning and irreversible visual loss associated with inappropriate corticosteroid treatment.
The publication additionally discusses practical prescribing considerations and reinforces the importance of careful ophthalmic examination prior to commencing topical corticosteroid therapy in patients with red eye presentations.
Acute Infective Endophthalmitis
Australian Family Physician (AFP), 2012
Key topics: postoperative infection, endophthalmitis, ophthalmic emergency, cataract surgery complications
Article Summary: This publication reviews acute infective endophthalmitis, a severe intraocular infection associated with rapid visual deterioration and potentially profound visual loss.
The article discusses common clinical presentations following cataract surgery or intravitreal procedures, including ocular pain, hypopyon, reduced vision and severe intraocular inflammation. Important risk factors, microbiological considerations and management principles are reviewed.
The publication emphasises the importance of urgent ophthalmic referral and early treatment, including intravitreal antibiotics and vitreous sampling, in order to optimise visual outcomes.
The Length of Superficial Temporal Artery Biopsies
Australian and New Zealand (ANZ) Journal of Surgery, 2007
Key topics: giant cell arteritis, temporal artery biopsy, vasculitis, diagnostic accurac
Article Summary: This comparative study evaluated temporal artery biopsy specimen lengths obtained at both a tertiary referral centre and a regional hospital in patients undergoing investigation for suspected giant cell arteritis.
The publication demonstrated that biopsy specimens measuring 20 mm or greater were significantly more likely to demonstrate histopathological features of giant cell arteritis than shorter specimens. The study highlighted the importance of obtaining adequately sized biopsy specimens in order to reduce false-negative results associated with skip lesions and segmental arterial involvement.
The article additionally discusses practical diagnostic considerations relevant to clinicians involved in the assessment and management of giant cell arteritis, an important ophthalmic emergency associated with irreversible visual loss if not recognised and treated promptly.
Increase in the Length of Superficial Temporal Artery Biopsy Over 14 Years
Clinical and Experimental Ophthalmology, 2016
Key topics: corticosteroids, giant cell arteritis, temporal artery biopsy, ophthalmic vasculitis, quality improvement
Article Summary: This study reviewed temporal artery biopsy practice patterns over a 14-year period at a tertiary referral centre and evaluated whether biopsy specimen lengths had improved following earlier recommendations regarding optimal specimen size in suspected giant cell arteritis.
The publication demonstrated a significant increase in average biopsy specimen length over time compared with earlier institutional audit data. Despite this improvement, giant cell arteritis positivity rates remained relatively stable.
The article reinforces the importance of specimen adequacy and careful surgical technique in the investigation of giant cell arteritis and highlights the multidisciplinary nature of management involving ophthalmologists, physicians and primary care clinicians.
Retinal Disease and Medical Ophthalmology
These publications examine retinal disease, systemic associations and evidence based medical ophthalmology relevant to both specialist and primary care practice.

Key topics: traumatic cataract, lens dislocation, retinal detachment, Indigenous eye health, rural ophthalmology
Article Summary: This publication describes the assessment of a 41-year-old Aboriginal patient from a remote Northern Territory community presenting with profound bilateral visual impairment. Examination revealed complete dislocation of the crystalline lens into the vitreous cavity in one eye, associated with chronic retinal detachment and traumatic mydriasis, together with a dense cataract in the fellow eye.
The article discusses the importance of considering traumatic and non-age-related causes of cataract in younger patients, particularly in rural and remote clinical settings where access to ophthalmic assessment may be limited. Clinical signs suggestive of previous ocular trauma are reviewed, including traumatic mydriasis, zonular instability and retinal detachment.
