Reported cases of hemifield slide phenomenon

This article reports three cases of hemifield slide, a phenomenon whereby there is an inability to stabilise and fuse visual hemifields. It occurs with heteronymous visual field loss and is thought to result from the loss of corresponding retinal points....

Assessing the quality of scars from incisions made by a Colorado needle or a scalpel

Traditional teaching has held the best scars are achieved with cold steel although no previous study has formally investigated this hypothesis in oculoplastic surgery. This paper describes a non-randomised cross-sectional study comparing the scar quality achieved from cold steel with...

Binocular training for amblyopia

The clinical effectiveness of binocular investigation for amblyopia was measured. The authors had previously unsuccessfully treated patients using occlusion and / or surgery. Patients were followed for an average of six months after cessation of treatment. The study included 22...

Brown’s syndrome surgery

Complications of surgery for Brown syndrome include under correction, extrusion of expanders and training for surgery. The authors introduced a procedure with minimal side-effects, accompanied by the application of the native tendon for superior oblique elongation. This was a prospective...

IOOA and DVD surgery

The authors report the results of bilateral modified inferior oblique (IO) transposition considering the equator in seven patients with infantile strabismus syndrome with inferior oblique overaction (IOOA) and dissociated vertical deviation (DVD). Mean age was 4.5 years (2-7) and mean...

B-scan ultrasonography

B-scan ultrasonography is commonly employed for the diagnosis and follow-up of ocular trauma. This retrospective study looked at the accuracy and predictive ability of B-scan ultrasonography following open globe repair. Of the 965 patients identified with open globe injuries at...

Early surgery for epiretinal membrane

This was a retrospective case review study in 120 consecutive patients with idiopathic epiretinal membrane. The average patient age was 72 years with a mean follow-up of 6.5 months. Inclusion criteria consisted of symptomatic patients with visual acuity of 1.0...

Resolution of mid-peripheral schisis in x-linked retinoschisis with the use of dorzolamide

X-linked retinoschisis (XLRS) is an early onset hereditary retinal dystrophy. It is caused by mutations of the RS1 gene. Common manifestations of XLRS are schitic lesions at the macula, as well as infero-temporal schisis. Carbonic anhydrase inhibitors have previously been...

Phakic iris clip lenses and endothelial cell loss

This retrospective observational study included long-term results on endothelial cell losses in highly myopic eyes, which underwent phakic iris-clip lens implantations. Included in the analysis were 113 eyes with mean preoperative spherical equivalent (SEQ) of -14.67 +/- 5.15 Diopters (D)....

Large collar diameter Jones tubes

This is the first report of the success rates of frosted Jones tubes with larger diameter, 4.5 or 5mm collars. This is a retrospective review of 29 eyes of 25 patients who underwent insertion of a large diameter collar frosted...

Use of technology in low vision rehabilitation

This article is a review of the accessibility features available on tablets and smartphones for the visually impaired. It explains exactly what the accessibility features are, how to access them and how to use them as well as some useful...

Pentacam vs. IOL Master keratometry measurement in IOL power calculations

The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...
