The rising age of pilots and the extension of retirement age underscore the importance of investigating Presbyopia correction intraocular lenses during cataract surgery for Aviation Pilots. This study aims to assess recommendations from aviation regulatory agencies, providing guidance on the use of multifocal intraocular lenses in both commercial and military pilots. A review analysed the perspectives of aviation regulatory agencies regarding the implantation of multifocal intraocular lenses in pilots.

In this paper, we review current strategies for calculating toric intraocular lenses (IOLs). We discuss the prevalence and clinical relevance of astigmatism and the assessment of toric IOL candidates. We detail recommendations for evaluating astigmatism and current biometry and IOL power calculation techniques.

Alzheimer's disease: A review of its visual system neuropathology. Optical coherence tomography-a potential role as a study tool in vivo.

Alzheimer's disease (AD) is a prevalent, long-term progressive degenerative disorder with great social impact. It is currently thought that, in addition to neurodegeneration, vascular changes also play a role in the pathophysiology of the disease. Visual symptoms are frequent and are an early clinical manifestation; a number of psychophysiologic changes occur in visual function, including visual field defects, abnormal contrast sensitivity, abnormalities in color vision, depth perception deficits, and motion detection abnormalities.

Prospects for adenovirus antivirals.

J Antimicrob Chemother

April 2005

Ophthalmology and Visual Sciences Research Centre, University of Pittsburgh, Pittsburgh, PA, USA.

Adenoviruses cause a number of self-limiting but often highly infectious diseases that affect multiple organs, most commonly those associated with respiratory, genitourinary and gastrointestinal tracts and the ocular surface. Many factors have driven a search for effective topical and systemic antivirals to adenoviruses. These include patient morbidity, economic losses and chronic visual disturbances associated with epidemic keratoconjunctivitis; and the startling recent trend of high morbidity and rising mortality associated with systemic adenoviral infections in the immunosuppressed, particularly paediatric bone marrow transplant recipients.
