Confocal microscopy and corneal graft rejection

Forty-five patients following penetrating keratoplasty (PK) were examined with the HRT III Rostock Cornea Module confocal microscope at various points after their surgery for two years. Activated keratocytes (AKs) were counted manually and their mean number evaluated. A pattern was...

Fixation disparity measurement

The authors evaluate different procedures looking at point zero, fixation disparity (FD) and motor fusion amplitude in order to calibrate the measurement of FD with Ogle’s apparatus with the overall goal to create a standardised measurement of the FD curve...

Correlation between peak intraocular pressure following water drinking test and pulsed methylprednisolone therapy

Steroids have long been known to cause increased intraocular pressures (IOP) in susceptible patients. Intravenous methylprednisolone is used to treat many rheumatological conditions and one of the risks is raised intraocular pressure. It would be useful to find patients at...

A prospective trial of adjuvant therapy for high-risk melanoma

Patients diagnosed with iris, ciliary body or choroidal melanoma of high-risk tumour cytogenetics (monosomy 3>/= 20% of cells), were treated with adjuvant low-dose dacarbacine (DTIC) and interferon –alpha-2b (IFNA-2b), following primary treatment (enucleation, brachytherapy or resection). DTIC was given intravenously...

Management options for microphthalmia with orbital cyst with / without visual potential

The authors present six cases (seven eyes) of congenital microphthalmia and orbital cyst. These cases were newborn mainly with one aged 20 years. There were four females and two males and two of seven eyes had a visual potential of...

Normative dimensions of the lacrimal gland

This article looks at the normative dimensions of the lacrimal gland in the axial and coronal plane on fat-suppressed T1 weighted contrast-enhanced magnetic resonance imaging (MRI). Previous data on this subject has come from computed tomography (CT). MRI is known...

Vigabatrin-induced retinal toxicity detected by 30Hz ERG

The purpose of this study was to assess the role of 30Hz flicker electroretinogram (ERG) as a marker for measuring changes in visual function over time in children receiving vigabatrin. This was an observational study of 11 children with mean...

Which cover test method is the best starting point for prescribing temporary prisms?

A retrospective review of medical records was completed, identifying consecutive patients prescribed Fresnel prisms for diplopia, assessed using both simultaneous prism and cover test (SPCT) and prism and alternate cover test (PACT) by a single orthoptist over a 36-month period....

Can OCT predict Alzheimer’s disease?

Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are based on facts and which are ‘fake news’. Headline: Can OCT predict Alzheimer’s disease? In 1986 Hinton et al. demonstrated evidence of optic nerve degeneration...

Addressing diabetes-related complications in Tanzania and Eswatini: A comprehensive approach to eye and foot screening

Diabetes is rising globally, particularly in low- to middle-income countries (LMICs), where healthcare systems are under resourced [1,2]. Among its complications, diabetic retinopathy (DR) and diabetic foot disease are preventable yet frequently overlooked [3-6]. These problems often develop together due...

Can diuretics increase the risk of acute angle closure glaucoma?

Diuretics, used widely in the treatment of hypertension, oedema, heart failure and liver failure, have been implicated in case reports in scientific literature to be linked to bilateral acute angle closure glaucoma (AACG). The aim of this study was to...
