Outcomes of combined medial and laser treatment for advanced Coat’s disease
In this study, the anatomical and visual outcomes of paediatric patients with advanced stage 3+ Coat’s disease are reported. Patients were treated with a combination of intravitreal ranibizumab, laser photocoagulation and methyl prednisolone acetate. This was a retrospective review of...
Effective contrast ratio as a measure of binocular visual perception
The authors used a binocular phase combination paradigm to quantitatively evaluate and compare the binocular visual perception of normal individuals and patients with different types of strabismus to understand the binocular visual perception of patients with strabismus and evaluate whether...
Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure
The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...
Effect of intravenous mannitol in post vitrectomised eyes
The purpose of the study was to evaluate the effect of intravenous mannitol 20% on intraocular pressure in vitrectomised silicone-oil filled eyes. A prospective analysis of consecutive patients was undertaken with their fellow eyes taken as controls. Thirty-one patients were...
Optical quality difference between monofocal and multifocal intraocular lenses
It is well known that multifocal intraocular lenses (IOLs) can generate more than one focus to restore distance and near vision, but patients may experience adverse optical phenomena such as decreased contrast sensitivity and induced glare or halos. The authors...
Effect of refractive corneal surgery on IOP and glaucoma progression
Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...
Results of changed treatment for retinoblastoma
Systemic chemotherapy was adopted in Kobe in 1996. In this study the authors analyse the clinical manifestations and results of treatment for patients with retinoblastoma since then. This review is of 43 eyes of 34 patients. Those with follow-up to...Feb/Mar 2015 Quiz 2

Literature review of OKN
The authors conducted a critical review of the optokinetic nystagmus (OKN) literature to consider OKN and in particular, vertical OKN. The review provides an overview of OKN to aid understanding of the eye movements. It provides a review of the...
Bacterial keratitis through the window of the known unknowns
This review article provides an up-to-date summary of current challenges in research and management of bacterial keratitis. The authors highlight that there is no current agreement on the criteria that should define bacterial keratitis; the role of investigation is unclear,...
