Five patients with unilateral orbital tumours are described in whom transient loss of vision occurred on deviation of the affected eye from the primary position. Other presenting features were diplopia, proptosis, poor visual acuity, visual field defects, pupillary abnormalities, fundal changes and altered colour vision. Abnormalities on fluorescein angiography suggest that the visual loss is d...

PURPOSE Activity limitations, which induce loss of autonomy in the elderly, are a major public health problem. We investigated the associations between objectively determined visual impairments and activity limitations and assessed the visual acuity thresholds associated with these restrictions. METHODS The study sample consisted of 1887 people aged 63 years and over from a population-based c...

PURPOSE Several studies indicate an increased mortality rate in older adults who have visual impairment, but few have attempted to address a potential causal mechanism. The goals of this study are to determine whether visual acuity loss increases the risk of dying and to examine whether depressive symptoms act as a mediator in this relationship. METHODS Data were derived from the 2520 older a...

Irreversible optic nerve dysfunction associated with central retinal vein occlusion (CRVO) is an unusual but important complication of Waldenstrom Macroglobulinemia (WM). Acute visual loss in CRVO is mainly due the severe macular oedema. However, ischaemic optic neuropathy needs to be considered in patients with CRVO when, (i) there is a relative afferent papillary defect and central scotoma, (...

All cases of corneal ulcers, presenting at the Aga Khan University Hospital, Karachi between January 2006 and December 2010 were reviewed. Information was obtained regarding socio-demography, the cause of ulcer, prior treatment and visual acuity. Afterwards, contact-lens specific information such as the type of lens and purpose and duration of lens usage was obtained from the participants by ph...
