Dehydrational crises: a major risk factor in blinding cataract.

Dehydrational crises: a major risk factor in blinding cataract.

An earlier case control investigation has indicated a strong relationship between dehydrational crises and risk of presenile cataract. A second methodologically distinct case control study of risk factors in cataract has been carried out in a population very different in terms of environmental and sociocultural characteristics from the population investigated in the earlier study in Central Ind...

Low Frequency Noise: A Major Risk Factor in Military Operations

Background. Noise is a major factor in many military environments. Usually the concern is with the higher frequency bands (> 500 Hz) that cause hearing damage or interfere with speech. Protection against noise is thus focused on these higher frequencies, while the bands of lower frequencies (< 500 Hz) are neglected, and non-audible bands, infrasound (< 20Hz) are ignored. In reality, long-term e...

Visual outcome after paediatric cataract surgery: is age a major factor?

AIMS To determine functional results after unilateral and bilateral cataract surgery in children with different aphakic optical correction. METHODS In this retrospective study, we evaluated visual acuity and binocular vision in 107 children who underwent cataract surgery during the 10 year period from 1985 to 1995. Aphakia was corrected by an intracapsular intraocular lens (IOL), spectacles o...
