Effects of phacoemulsification on IOP and drug use in glaucoma

For patients with comorbid cataract and primary open-angle glaucoma (POAG), guidance is lacking as to whether cataract extraction and traditional filtering surgery should be performed as a staged or combined procedure. Achieving this guidance requires an evidence-based understanding of the...

Glaucoma and erectile dysfunction

In this cross-sectional study with patient questionnaire and retrospective chart review, a total of 167 male patients over 40 years of age were enrolled. Exclusion criteria included previous exposure to radiation and surgical treatment for prostate benign hypertrophy or malignancy....

Use of amniotic membrane in second stage Hughes tarsocunjunctival reconstruction

This is a retrospective, non-comparative interventional case series of 30 patients who underwent amniotic membrane transplantation to lower lid margin as part of Hughes lid reconstruction to prevent a hyperaemic, hypertrophic conjunctival margin with excessive discharge. Patients undergoing more than...

Lester Jones tubes: Can these be tolerated long-term?

The authors present a retrospective case review study of a cohort of patients with Lester Jones’ tubes first placed between 1969 and 1989, and who were reviewed within the last 15 years. Twenty-nine patients (33 eyes) were included in the...

Unravelling ocular motility

Ocular motility can often be a slightly abstract concept during the earlier years of ophthalmology training. A large variance on what embodies normality; mythical concepts like fusion and binocular vision, examination techniques that can be fiddly, and complex neuroanatomy all...

Stereotactic radiotherapy for polypoidal choroidal vasculopathy

Polypoidal choroidal vasculopathy (PCV) is a variant of neovascular AMD. It is a disease of choroidal vasculature characterised by abnormal branching vascular network with aneurysmal dilatations (polyps). Features of PCV include pigment epithelial detachments (PED), subretinal fluid (SRF) accumulation and...

Prediction errors of formulas in optical biometers

This study was conducted retrospectively in a private practice setting. Nine formulas were compared for prediction error (postoperative spherical equivalent (SE) minus, predicted SE calculated by each formula), using two optical biometers (Lenstar – optical low coherence reflectometry (OLCR) and...

Anatomical variations of the nasolacrimal system

The authors report a retrospective observational case series of 734 dacryocystography images; 689 from adult patients and 45 from paediatric patients. Of these 734 images, 35 (4.8%) were found to have an anatomical variant where the nasolacrimal duct emerged from...

Allergic conjunctivitis evaluation by thermography

Thermography is a non-invasive imaging technique, which uses infrared radiation reflected from an object to estimate the temperature of the object. This paper evaluates the use of thermography to assess allergic conjunctivitis objectively, by using an instrument called ocular surface...

Radiotherapy for orbital apex cavernous haemangiomas

This is a review of six patients with cavernous venous malformations (haemangiomas) involving the orbital apex who were treated with fractionated stereotactic radiotherapy. Patients were diagnosed on MRI imaging with only one having had previous surgery to debulk the lesion....

GA position of eyes

The authors assessed eye position based on the corneal reflex position (Hirschberg test) using a standardised measurement on pictures taken at the preoperative evaluation and under general anaesthesia (GA) in 41 patients. The mean ocular deviation taken at the preoperative...

Human factors in the operating room

The importance of minimising human error in surgery is well established. This was initially sparked by lessons learned from the aviation industry in the 1970s after several fatal flight accidents [1]. This became a catalyst for a movement on training...
