Validation of the colour difference plot scoring system analysis of the 103 hexagon multifocal electroretinogram in the evaluation of hydroxychloroquine retinal toxicity.
To evaluate sensitivity, specificity and reproducibility of colour difference plot analysis (CDPA) of 103 hexagon multifocal electroretinogram (mfERG) in detecting established hydroxychloroquine (HCQ) retinal toxicity. ⋯ Colour difference plot analysis had sensitivity and specificity that approached that of ring ratio analysis of R5/R4 P₁ responses. Ease of implementation and reproducibility are notable advantages of CDPA.

To investigate the clinical features of all patients with acute-onset diplopia presenting to the ophthalmology department. ⋯ Acute onset diplopia is an uncommon and challenging presentation for the ophthalmologist to manage. These results demonstrate that the aetiology is commonly identifiable at the first presentation based on clinical evaluation, only a small percentage require urgent radiological investigation and a small minority of cases are likely to have serious emergent pathology.

Prevalence and risk factors of visual impairment and blindness in Korea: the Fourth Korea National Health and Nutrition Examination Survey in 2008-2010.
To describe the age, gender specific prevalence and risk factors of visual impairment and blindness in Korea. ⋯ The prevalence of visual impairment was demonstrated to be higher while that of blindness was similar to previous population studies in Asia or U.S. Sociodemographic disparities are present in the prevalence of visual impairment and more targeted efforts are needed to promote vision screening in high risk groups.

Comparative Study Observational StudyAnalysis of spectral domain optical coherence tomography measurements in optic neuritis: differences in neuromyelitis optica, multiple sclerosis, isolated optic neuritis and normal healthy controls.
To compare the retinal layer thickness of eyes with optic neuritis (ON) and that of control eyes and ON eyes with and without neuromyelitis optica (NMO) or multiple sclerosis (MS). ⋯ Our SD-OCT data revealed a notable difference in the GCL + IPL thickness between ON and healthy control eyes. It also showed differences in the thickness of several retinal layers for ON subgroups including NMO, MS and isolated ON. This may be helpful for distinguishing the aetiology of ON.
