Ground control to optic nerve – the space oddity to be studied
The authors explore the clinical entity that is known as Spaceflight Associated Neuro-ocular Syndrome (SANS). Its clinical characteristics include optic disc oedema, hyperopic refractive shifts, globe flattening, and chorioretinal folds, may pose a health risk for future space exploration. Understanding...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...

Correlation between anti-retinal antibodies and proliferative vitreoretinopathy (PVR)
The pathological basis of PVR is not clearly understood and there are no effective medications targeting this condition. This cross-sectional study looked at the possible association of anti-retinal antibodies with patients with PVR and retinal detachment (RD). Aqueous and vitreous...Observership in Dar es Salaam
