Causes of photophobia in adults and children

This retrospective case review identified individuals of any age with visual discomfort using billing records over an eight-year period. These records were screened for photophobia / light sensitivity as a main symptom or documented during examination. Data including demographics, medical...

Photophobia: an unusual symptom of a pituitary macroadenoma

Introduction Photophobia, defined as ‘an abnormal intolerance to light’, is commonly associated with a range of both ocular and neurological pathologies such as dry eye, blepharospasm, corneal pathologies, cataracts, uveitis, retinal dystrophies, optic neuritis, migraine, meningitis, and traumatic brain injury...

ROPPVAL Syndrome as a differential diagnosis to optic neuritis

Optic neuritis (ON) is a common cause of visual loss in young patients. Patients with eye pain and ipsilateral visual loss are often referred into neuro-ophthalmology clinics with a possible diagnosis of ON. In 2018 Jefferis et al. reported a...

Light tolerance in infectious keratitis

The authors presented the findings of a study that aimed to identify the maximum irradiance (power received by a surface per unit area) that can be tolerated by photophobic patients with infectious keratitis (IK). They recruited 30 patients (14 women...

Assessing and treating achromatopsia

This literature review considers clinical characteristics (pendular nystagmus, poor visual acuity, lack of colour vision and marked photophobia), genetics (autosomal recessive disease, with CNGA3, CNGB3, GNAT2, PDE6C, PDE6H and ATF6 gene mutations), diagnostic options (OCT and fundus auto fluorescence), and...

Recognising clinical characteristics of blepharospasm

Focal dystonia is regarded as a characteristic feature of blepharospasm, but patients do not always present with these motor symptoms. The authors present a retrospective analysis of data from a large number of patients treated for drug-induced or essential blepharospasm...

Long-term treatment of blepharospasm using Botulinum Toxin A

The authors report findings from a retrospective single-centre study which aimed to evaluate the efficacy and safety of long-term botulinum A toxin (BAT) treatment in patients with blepharospasm (BPS). Blepharospasm is described as one of the most frequent types of...

Visual snow syndrome: a review

Visual snow syndrome (VSS) is a neurological condition characterised by visual phenomena described as dots moving across the visual field. Other visual symptoms can take the form of palinopsia, entopic phenomena, photophobia and nyctalopia. Tinnitus and migraine can be commonly...

Conjunctivochalasis and aqueous tear deficiency – which one causes symptoms?

This review sought to determine whether conjunctivochalasis (CCh) obliterates the fornix tear reservoir and thus mimics aqueous tear deficiency (ATD). Patients were divided into two groups, with aqueous tear deficiency (CCh +ATD) or without (CCh –ATD), based on results of...

Effect of voriconazole of vision of healthy volunteers

Voriconazole is a broad spectrum, triazole antifungal agent used for systemic fungal infections. It has a favourable safety profile and is available in both intravenous and oral forms. The commonest adverse drug reactions with voriconazole are changes in visual perception,...

Effect of laser wavelength on delivering effective burns through opaque lens using pattern scan laser

Panretinal photocoagulation (PRP) has been used in the treatment of various retinal disorders for many decades. Conventional single-spot lasers take quite some time to do with significantly higher pain, anxiety and photophobia when compared to the pattern scan laser (PSL)....

Intermittent exotropia

Four cases of intermittent exotropia are discussed. Case 1 was a nine-month-old with cycloplegic refraction of +1.0DS and a 30PD intermittent exotropia at near and distance. Discussions considered observation, part-time occlusion, refractive correction and later possibility of surgery. Case 2...
