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...

Long-term open angle glaucoma cohort study

This was a study to estimate the development of open angle glaucoma (OAG) in a screened and re-examined elderly group as compared to an unscreened group during the same time period. The participants comprised of 856 individuals born in 1915...

AC/A non-linearity

This study investigated whether or not the response accommodative convergence to accommodation (AC/A) ratio in 30 visually normal subjects is linear with lens presentation order counterbalanced. Accommodative response was measured using the Shin Nippon SRW 500 infrared autorefractor. Accommodation was...

SLT short-term results

The aim of the study was to evaluate the risk of adverse effects and short-term results after 360 degrees selective laser trabeculoplasty (SLT) in glaucoma patients. The authors enrolled 64 eyes of 64 patients all who had poorly controlled primary...

Diabetic retinopathy and body fat distribution and adipokine secretion in type 2 diabetics

The major risk factors for diabetic retinopathy (DR) in patients with diabetes are poor glycaemic or blood pressure control, duration of diabetes and nephropathy related to the severity of DR. Several studies suggest that DR is associated with visceral fat...

Visual outcomes, visual fields and optical coherence tomography in paediatric craniopharyngioma

This study reviews the visual outcomes of ten patients under the age of 18 years with craniopharyngioma. The paper also reviews the correlation between visual field (VF) testing and optical coherence tomography (OCT) examination and evaluates the role of OCT...

Saccadic differences under cover test

Patients with intermittent exotropia and exophoria plus ortho subjects underwent measurement of saccadic reaction times (SRTs) to compare those occurring in one eye and those occurring with alternating cover tests (ACTs). Twenty-five subjects were studied. Results for the intermittent exotropia...

Under pressure: intraocular pressure and bariatric surgery

Obesity in the general patient population is increasing. The National Institute for Health and Care Excellence recommends bariatric surgery with body-mass index (BMI) of over 40, or between 35-40 and other significant disease that could be improved with weight loss....

Choroidal vascularity in NAION

The authors present a cross-sectional, non-interventional study of healthy volunteers and those with non-arteritic anterior ischaemic optic neuropathy (NAION) recruited over a six-month period at a single site. NAION is the most common cause of acute optic neuropathy over the...

Fusional vergence measurement

This paper reports a systematic review to address two objectives: 1, to compare the normative values of tests measuring fusional vergence; 2, to investigate sources of heterogeneity of prism accuracy. The review was conducted according to PRISMA guidelines with a...

Choice of cycloplegia regime

The purpose of this randomised control trial (RCT) was primarily to compare the refractive outcome of atropine 0.5% (A) instilled twice daily at home 2.5 days before measurement versus two drops of 1% cyclopentolate (CC) in one eye versus one...

Accuracy of intraocular lens power calculations in paediatric eyes

A study comparing the accuracy of the SRK II, SRK/T, Hoffer Q, Holladay 1, T2 and Super formula in predictive refractive outcomes in children undergoing primary IOL insertion into the capsular bag following cataract surgery. A total of 377 eyes...
