Anterior segment OCT predicts gonioscopic angle closure

This is a prospective observational study of 342 subjects over four years. Sixty-five were controls who had open angles both on gonioscopy and AS-OCT, while 277 had open angles only on gonioscopy but iridotrabecular contact (ITC) on AS-OCT (one to...

PD-1 and retinal ganglion cell death

Death of retinal ganglion cells (RGC) in conditions like glaucoma leads to permanent visual loss. RGC death can be due to the initial stress such as raised intraocular pressure or secondary to mechanism such as oxidative stress. Programmed cell death-1...

Selection of visual field test for detection of pituitary disease

This prospective cross-sectional diagnostic accuracy study compared Octopus semi-automated kinetic perimetry (SKP) and Humphrey static automated central perimetry for detection of neurological visual field loss in patients with pituitary disease. Humphrey central 30-2 SITA threshold programme results were compared with...

Nicotine accelerates diabetes induced retinal changes

This study investigated the influence of nicotine in an experimentally induced diabetic rat model. They used non-invasive high-resolution spectral domain optical coherence tomography (SD-OCT) imaging to provide quantitative information on the temporal alterations of retinal structures at the micrometer resolution...

Long scleral tunnel technique to prevent tube exposure of Ahmed glaucoma valve

This retrospective study was done to evaluate the efficacy of long scleral tunnel technique and compare it with pericardium patch graft in preventing tube exposure of Ahmed glaucoma valve. Seventy-eight eyes of 73 patients were included. In group 1 patients,...

ABDO graduation

The Association of British Dispensing Opticians (ABDO) celebrated the graduation of dispensing opticians and contact lens opticians at Canterbury Cathedral on Wednesday 24 April.

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...

RPE use similar pathway to regulatory T cells to inhibit immune response

Retinal pigment epithelial (RPE) cells form an important part of the blood-retinal barrier that protects the neuronal cells responsible for sight. RPE cells are involved in innate and adaptive immune responses via expression of surface molecules and release of cytokines....

Polymerase chain reaction evaluation of infectious multifocal serpiginoid choroiditis

This paper presents a retrospective review of infectious agents associated with multifocal serpiginous choroiditis (MSC) based on polymerase chain reaction (PCR) evaluation and specific antimicrobial therapy. The study included 13 patients with MSC who were evaluated with PCR for the...

Vital dyes in ophthalmology

This comprehensive review gives an excellent summary of the uses and properties of the different dyes available to aid better visualisation and diagnoses in ophthalmology. The authors clearly display the pharmacological properties, molecular details, osmolarity and indications in clinical ophthalmology...

Patient-reported outcomes in oculoplastic surgery

This is an important if somewhat difficult to grasp article which tries to formally address the subject of patient-reported outcomes in oculofacial surgery. The authors have conducted an extensive review of the literature searching for instruments (questionnaires) which have been...

MicroRNA mediate retinoblastoma signal transduction

MicroRNAs (miR) are small non-coding single-stranded RNA molecules, normally 22 nucleotides long. There is a large family of miR that control protein expression by binding to mRNAs, leading to their degradation. One important role of miR is in tumours where...
