Statins inhibit TGFβ2 mediated fibrotic response in astrocytes

Glaucoma is a common condition where increased ocular pressure can lead to death of retinal ganglion cells due to impaired drainage of fluid from the eye. One mechanism involved in glaucoma is remodelling of the extracellular matrix at the lamina...

Intravitreal aflibercept for diabetic macular oedema

The VISTA and VIVID randomised phase 3 trial were designed to compare the efficacy and safety of intravitreal aflibercept injections versus laser photocoagulation for diabetic macular oedema (DMO). A total of 872 patients with centrally involving DMO were recruited, and...

Dyslexic reading improved by vergence training

The aim of this study was to evaluate if reading performance could be improved by a period of compensatory vergence training in dyslexic children with otherwise normal binocular vision. The study included 13 children with dyslexia – mean age of...

Precision and accuracy of TearLab osmometer

Measuring tear osmolarity has been identified as a potential method for objectively diagnosing dry eye. TearLab osmolarity system is an in situ osmometer which may be a promising candidate for clinical use as it is portable and only requires a...

Beliefs and adherence to glaucoma treatment

The aim of the study was to determine adherence rates and beliefs about glaucoma and its treatment in white Americans, African Americans, white Australians and Singaporeans of Chinese descent. A cross-sectional study of 475 glaucoma patients using topical eye drops...

B-scan ultrasonography

B-scan ultrasonography is commonly employed for the diagnosis and follow-up of ocular trauma. This retrospective study looked at the accuracy and predictive ability of B-scan ultrasonography following open globe repair. Of the 965 patients identified with open globe injuries at...

PD-1 and PD-L1 in exenteration specimens

This is an immunohistochemical study looking at variation in the expression of the programmed death-1 receptor (PD-1) and the programmed cell death ligand-1 (PD-L1), comparing cutaneous malignancies which invaded the orbit with uncomplicated nodular basal cell carcinomas. The authors retrospectively...

Smartphone use and its effects on eyes

Longitudinal pilot study on 12 young healthy adults comparing effects of smartphone use over a 60-minute period. Reading conditions and smartphone use was standardised for all participants. Ocular symptoms, tear function and binocular vision were assessed before and after each...

Online retinoblastoma surveillance tool

Given the vision and life-threatening course of retinoblastoma (RB), it has become a significant heritable childhood cancer to screen for. To recommend surveillance, risk must be estimated and genetic testing plays a vital role. However, genetic tests vary based on...

Differences between ages and onset in functional network changes associated with reading Braille

Visual impairment affects learning ability, speed and accuracy required for reading, writing and learning memory in terms of educational performance. Braille training requires decoding of simple dots into meaningful words and sentences. The objectives of this study were to evaluate...

Test combination which could detect prodromal Alzheimer disease

The authors prospectively recruited a convenience sample of individuals aged over 65 and either with a diagnosis of mild cognitive impairment (MCI) due to Alzheimer disease or normal cognition. Other types of dementia and severe neurological conditions were excluded. All...

Computer-assisted surgery in the orbit

In this paper the authors describe the growing use of computer-assisted surgery in ophthalmology. It is already described as a powerful adjunct in neurosurgery and sinus surgery and here they describe their experience of using it for the orbit; specifically...
