Intravitreal injection related endophthalmitis

This article reviews the incidence, clinical findings, risk factors, management and visual outcomes in intravitreal injection related endophthalmitis. Incidence of this complication is reported to be in the range of 0.038% to 0.065% (1 in 2000-3000 injections). Patients present typically...

Blinking and driving

Spontaneous blinking is dependent on cognitive processes and is regulated by a central pacemaker that is highly sensitive to the attention demands and cognitive workload of the visual task in hand. There is evidence of a variability in the frequency...

Cataract surgery in patients with retinitis pigmentosa

Retinitis pigmentosa (RP) is the commonest inherited cause of retinal degeneration. Posterior subcapsular cataract (PSC) develops in 41% to 90% of these patients by age 40 years. In this retrospective study, the authors have evaluated surgical outcomes in patients with...

Cost-effectiveness framework discussion for vision screening

The authors present a discussion paper on hypothetical, but representative, examples of post-referral costs that may result from different screening options up to the point of discharge from specific services. Data was taken from a recent (2019) systematic review (with...

Strategies for managing neovascular AMD and DMO in routine clinical care

Treatment practice in the management of neovascular age-related macular degeneration (AMD) and diabetic macular oedema (DMO) illustrate increasing adoption of patient-tailored treatment approaches based on initial diagnosis and regular monitoring of imaging and visual outcomes in routine clinical care. The...

A case of post-viral ocular microflutter

A number of eye movements disrupt visual fixation, one such movement being saccadic intrusions which are described as small involuntary saccadic movements. Among saccadic intrusions without intersaccadic intervals, ocular flutter and opsoclonus are prominent. When the saccadic amplitude is very...

Genetic analysis of choroideremia families

Choroideremia (CHM) is a rare X linked recessive chorioretinal dystrophy. Symptoms include nyctalopia and progressive peripheral field loss. Female carriers may have mild symptoms. Choroideremia is known to be caused by a mutation in the CHM gene. A multicentre human...

Outcomes at 100 weeks from the LEAVO study of intravitreal anti-VEGF therapies for macular oedema secondary to central retinal vein occlusion

Royal College of Ophthalmologists Annual Congress 2019, Glasgow - First presented and discussed on Monday 20 May 2019, with a further presentation of results during Retina Subspecialty Day on Thursday 23 May 2019. Among patients with macular oedema secondary to...

Is DSAEK or DMEK better for failed penetrating keratoplasty (PKP)?

This retrospective study involved 52 patients with failed penetrating keratoplasty. Twenty-eight eyes underwent Descemet membrane endothelial keratoplasty (DMEK) and 24 eyes underwent Descemet stripping automated endothelial keratoplasty (DSAEK). Data collection included demographic characteristics, number of previous corneal transplants, previous glaucoma...

Vision screening standards for fitness to drive

Most countries require that vision meets a pre-defined standard in order to be legally permitted to drive, but these standards vary widely. The primary method by which vision is assessed to determine suitability for driving is by measuring visual acuity...

A comparative evaluation of a new diffractive trifocal and EDOF IOLs

This study aimed to compare the outcomes of two diffractive trifocal intraocular lenses and one extended depth of focus (EDOF) intraocular lens (IOLs). This was a six month, single centred, prospective, randomised, comparative study in which patients who underwent routine...
