Clinical evaluation of a new pupil independent diffractive MIOL lens with a ±2.75D near addition

This is a clinical outcome assessment after cataract surgery with implantation of multifocal intraocular lens implant IOL with a lower near addition (+2.75D) of 143 eyes of 85 patients aged between 40 to 83 years of age. The type of...

A practical guide to anisocoria

Anisocoria means the presence of difference in the size of the right and left pupils. It is a sign of an abnormality in the efferent pathway. The first question facing the ophthalmologist is to ascertain if anisocoria is present or...

The assessment of pupils and 
pupillary reactions

Understanding pupillary reactions is vital in understanding basic neuro-opthalmology. It is a skill required in eye casualty, clinics and perhaps most importantly, exams. To start at the beginning, the pupil is the central aperture of the iris, its size controlling...

A case report of alternating anisocoria with associated nasal congestion

The authors have described a group of healthy individuals who show alternating anisocoria, in a previous paper. In these cases, the pupil asymmetry alternates between eyes every few hours, with no observed instances when both pupils are equal in size....

An unusual case of silicone oil in the anterior chamber simulating intraocular implant

Silicone oil internal tamponade has been used for over 50 years, even prior to pars plana vitrectomy [1].Over a course of time silicone oil may migrate to the anterior chamber through the pupil. This may disperse in the form of...

Measuring IPD with PlusoptiX

The authors evaluated the accuracy of the PlusoptiX A04 for measuring pupillary distance as compared to measurements taken by a trained optician. This retrospective review included 256 children who had undilated PA04 screening and had pupil distance measurement done by...

Intracameral mydriasis with Mydrane

The aim of this study is to evaluate the ‘real world’ experience in a UK setting for intracameral Mydrane mydriasis in routine cataract surgery. A prospective consecutive series of 60 patients (group 2) had intraoperative, intracameral Mydrane (tropicamide 0.02%, phenylephrine...

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

The authors report on a study to examine the effects of the Mydriasert insert on time, effects, patient comfort and tolerability at Manchester Royal Eye Hospital. Mydriasert is an insoluble ophthalmic insert indicated for mydriasis prior to ophthalmic surgery, which...

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...
