RAPD in glaucoma screening
A study was conducted to investigate the relative afferent pupillary defect (RAPD) by swinging flashlight as a potentially useful screening test for glaucomatous optic neuropathy. The authors recruited 107 subjects with or without glaucoma from a clinic population. A medical...Crystalline keratopathy in monoclonal gammopathy of undetermined significance
Monoclonal gammopathies encompass a group of plasma cell disorders characterised by the excessive production of abnormal monoclonal immunoglobulins in the bloodstream [1]. This category includes multiple myeloma, monoclonal gammopathy of undetermined significance (MGUS), amyloidosis and other lymphoproliferative disorders. Monoclonal gammopathy...
Rituximab as an immunosuppression treatment for thyroid eye disease
Thyroid eye disease is traditionally treated with high dose glucocorticosteroids and surgical orbital decompression, where responses are often inadequate. This medical treatment is centred around symptom control and reduction of thyroid hormone synthesis, not immunosuppression. Rituximab is an anti-CD20 monoclonal...The results of the last survey Feb 2020
I appreciate that I keep on reiterating it, but again we see so much practice variance. Who is right and who is wrong? Is there a right or wrong approach? And does it matter? I think it probably does matter....Cataract surgery training in the independent sector
I am now most of the way through my ST3 year working in Plymouth, within the Peninsula Deanery. Before the start of the year, I was approached by one of my consultants who asked if I would like to carry...
E-Dobson card for visual acuity
The authors assessed the utility of an electronic Dobson acuity card which can be altered for spatial frequency. Thirty-six infants and toddlers aged 5-36.7 months were recruited – equal females and males. Fourteen had high refractive error. The card is...
Binocular summation with low contrast
The magnitude of binocular summation was investigated in normal control subjects using four different letter charts of varying type with fixed and variable contrast levels and spatial frequency to determine which tests most readily reveal binocular summation in normal subjects....
Perceptual learning treatment for amblyopia
The authors previously conducted a feasibility study examining the potential benefit of a self-administered at-home use of a tablet-based perceptual learning (PL) game. Visual stimuli were presented in various orientations and spatial frequency in a game-play format. This study evaluates...
Screening for visual processing deficits in dementia
The Queen Square Screening test for Visual Deficits (QS test) screens for changes in visual processing. It has never been formally validated as a single test. The test consists of a short booklet developed using remnant object and spatial perception...
