Effect of low-dose atropine on myopia progression

Spot screener versus Grand Seiko measurements

The authors aimed to determine repeatability and reproducibility of refractive values and pupil size measured using the Spot Vision Screener and to compare its measurement values with the Grand Seiko autorefractor. This was a cross-sectional study of 22 healthy adults;...

How to examine the visual system Part 2: Accommodation, pupils, fundoscopy and additional tests

A novel computerised portable pupillometer detects and quantifies relative afferent pupillary defect

We have all had referrals from A&E telling us that a patient can’t see out of one eye. Sleepily we may ask “Is there an relative afferent pupillary defect (RAPD)?” to evaluate the seriousness of the presentation. The response is...

Prostaglandin levels in femto cataract surgery

Following previous reports of pupil size decrease after femtosecond treatment, the authors compare levels of prostaglandins in patients undergoing femtosecond assisted cataract surgery with those having routine cataract surgery. Patients with inflammatory eye disease, previous trauma surgery, age-related macular degeneration...

Screening accuracy

In this study the authors observed whether and how well orthoptic tests are performed by non-orthoptists in a screening setting. They assessed the quality of screening tests by semi-structured observations of youth health care (YHC) physicians who screened children aged...

Do patients with prolactinomas using dopamine agonist drugs have autonomic dysfunction?

This prospective study aimed to determine whether there is autonomic dysfunction in patients with prolactinomas using dopamine agonist (DA) drugs by measuring static and dynamic pupillary responses using an automatic pupillometric device.Included were 25 eyes from 25 patients who were...

Smartphone ophthalmoscopy vs. slit-lamp biomicroscopy in diabetic retinopathy

In this prospective, comparative, clinical study the authors’ aim was to assess the reliability and accuracy of smartphone ophthalmoscopy as compared with standard slit-lamp biomicroscopy in the grading of diabetic retinopathy. One hundred and twenty consecutive, new, diabetic patients underwent...
