The rarebit vision test for macular conditions

Rarebit testing is used to measure low degrees of neuro-visual damage and is available for free on the internet. It consists of a fixed bright light dot presented on a black background. During testing it is presented briefly at different...

Functional visual field loss using automated static perimetry

Functional visual field loss is traditionally assessed by kinetic perimetry, typically producing spiralling isopters. This study looked at the spatial distributions of functional field deficits using automated static perimetry. A retrospective review of automated perimetry records was conducted using a...

Long-term open angle glaucoma cohort study

This was a study to estimate the development of open angle glaucoma (OAG) in a screened and re-examined elderly group as compared to an unscreened group during the same time period. The participants comprised of 856 individuals born in 1915...

Long-term outcomes for hereditary retinoblastoma

Earlier diagnosis and more rigorous treatment regimens have contributed to better outcomes for patients with retinoblastoma. This study looked at 24 patients with hereditary bilateral retinoblastoma treated with systemic chemotherapy during a ten year period (2001-2011). The medical notes were...

Nystagmus and associated diagnosis

Patients with nystagmus attending a Low Vision clinic in Sweden were included in this study. Medical records were reviewed to exclude those with general diagnoses that could explain the nystagmus. The remaining group of patients underwent subjective refraction, retinoscopy, ocular...

Effects of topical anaesthetic on intraocular pressure

This prospective interventional study assessed the effects of repeated intraocular pressure (IOP) using Goldmann applanation tonometry and applanation resonance tonometry in six volunteers. Previous literature supports IOP reduction using repeated applanation tonometry. Repeated IOP measures were taken alternately on 12...

Visual defects in deaf children and young adults

This literature review article serves as a great update on the current evidence relating to visual defects in the young deaf population. There is a good introduction with background information and demographic data relating to UK hearing impairment. The authors...

Gender variations in retinopathy

The Tromso Eye Study is a substudy of the Tromso Study; a population based longitudinal study based in Norway. The extensive 5869 participants had no diabetes and were aged between 30-87 years. Retinal images from both eyes were taken using...

Cavernous sinus syndrome

Anatomically the cavernous sinus is a plexus of multiple veins that are connected and within this plexus there are several important vascular and neurological structures. These include cranial nerves III, IV, V1 (and sometimes V2), VI as well as the...

Microperimetry of subretinal drusenoid deposits

Subretinal drusenoid deposits (SDD), originally termed ‘reticular pseudo-drusen’, have recently been identified by histology and optical coherence tomography (OCT) as aggregations located in the subretinal rather than the sub retinal pigment epithelium (RPE) space. These deposits affect the amount of...

Time domain vs. spectral domain in the measurement of the optic nerve head

The authors describe a prospective study of 40 participants (20 healthy and 20 with glaucoma) enrolled to compare the measurements of the optic nerve head (ONH) parameters given by time domain (TD) and spectral domain (SD) optical coherence tomography (OCT)....
