Myopia in Han Chinese

The authors present a case-control study of 361 patients with high myopia (mean spherical equivalent of -6.0DS or lower, and axial length greater than or equal to 26mm) and 749 healthy controls (mean spherical equivalent -1.0 to +1.0DS). They tested...

Tocilizumab in Graves’ orbitopathy

This prospective European study looks at the response to tocilizumab in corticosteroid-resistant disease. Tocilizumab (TCZ) is a monoclonal antibody that competitively inhibits IL-6 binding to its receptor. Unlike teprotumumab, the advantage of TCZ is that it is already used within...

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...

Influence of overall intraocular lens diameter on rotational stability

It has been shown that approximately one in three patients undergoing cataract surgery have >1.0D corneal astigmatism and managing this during surgery is important to achieve good refractive outcomes. One of the widely used ways of reducing preoperative astigmatism during...

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...

Conjunctival inflammation in glaucoma patients

Numerous studies have demonstrated that topical medications and preservatives used for the management of glaucoma can induce significant histopathologic and inflammatory changes in the ocular surface. This study describes an increased expression of major histocompatibility complex class II antigen HLA-DR,...

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....
