Sustained elevation of extracellular ATP in chronic glaucoma

Although adenosine 5′-triphosphate (ATP) release from retinal neurons and astrocytes has been demonstrated in short-term increases in intraocular pressure (IOP); such as in aqueous humor of humans with primary acute angle closure glaucoma, the response in chronic IOP elevation was...

The interpretation and use of ultrasound biomicroscopy (part 1)

Ultrasound Biomicroscopy (UBM) has become increasingly important for the diagnosis of a variety of anterior segment pathologies. Most ophthalmologists are familiar with conventional B-scan ultrasonography techniques, which operate at lower sound frequencies (7.5 to 20MHz). UBM is an ultrasound technique...

Modified technique in place of ultrasound biomicroscopy

The authors describe a modified immersion B-scan ultrasonography that includes a standard B scan probe of 10MHz, a surgical glove and sterile saline to fill a finger of the surgical glove – tied off to create the desired immersion standoff...

Uveitis in the elderly

This study from Turkey evaluated the causes and clinical characteristics of uveitis in elderly patients. Data from 90 eyes of 68 patients aged 60 years and older were reviewed. Anterior uveitis was present in 75% (33% of these had keratouveitis),...

Autologous scleral button for anterior defect in evisceration surgery

This is a small case series of five patients who have had evisceration surgery using a new technique. The anterior defect created when removing the corneal button has been closed by taking an autologous posterior scleral graft inferomedial to the...

Myopia-related strabismus – heavy eye syndrome

Introduction Myopia can be associated with any type of strabismus, but high myopia has increased frequency of esotropia and vertical heterotropia. The incidence and severity of the strabismus increases with the degree of myopia and age of the patient. Classification...

Uveitic glaucoma

The purpose of this retrospective study from two tertiary Institutions in Israel over a period of 13 years, is to present the long-term outcomes of uveitic glaucoma and to identify risk factors for progression. The study included 34 patients (53...

Cataract surgery in uveitis patients

Cataract formation is a common complication of uveitis, causing up to 40% of vision loss in these patients. Cataract results from inflammation +/- corticosteroid therapy and is usually posterior subcapsular, but a small proportion have a rapid increase in nuclear...

Globes in space: What would happen to our globes on the globe of Mars?

Many films have been made regarding life on alternative planets. With the Mars One mission approaching in 2023, there are high expectations regarding future interplanetary travel. The authors provide an ophthalmology perspective on what could happen to our eyes if...

Heidelberg Engineering emphasises Anterior Segment Focus under new Clinical Director

Steve Thomson joins Heidelberg Engineering as Clinical Director to further strengthen the Anterior Segment product development team.

Risk factors for intraoperative floppy iris syndrome

Intraoperative floppy iris syndrome (IFIS) is charcterised by flaccid iris stroma leading to fluttering and billowing of iris, tendency of iris to prolapse through surgical incisions and causing intraoperative pupil constriction. IFIS is characterised as complete when all three features...
