results mean age was 41.6 ± 9.2 for the military truck drivers and 43.4 ± 10.9 for commercial truck drivers (p > 0.05). no significant difference between military and commercial drivers was found in terms of driving experience, number of mvcs, binocular va, frequency of color vision defects and cs scores. in contrast, the last ocular examination was significantly earlier in military drivers tha...

purpose : to evaluate the biomechanical changes of cornea after intracorneal ring segment (icrs) implantation in keratoconic eyes methods : in this study, 1 or 2 icrs were inserted in 17 keratoconic eyes. best spectacle-corrected visual acuity (bscva), uncorrected visual acuity (ucva), refraction, and keratometry were evaluated preoperatively and 1 and 3 months after surgery. corneal hysteresis...

PURPOSE To determine the impact of vision impairment and eye diseases on vision-specific quality of life and visual function in an older population of rural southern India. METHODS Presenting and best-corrected visual acuity and burden of eye diseases were determined in a population aged 40 years and older, identified through a random cluster sampling strategy from 50 villages of rural south ...

purpose: to assess the efficacy of polyhexamethylene biguanide (phmb) in treating acanthamoeba keratitis (ak) and also to identify related factors affecting final visual outcome in ak patients treated with phmb methods: in these interventional case series study, 27 eyes of 25 patients with ak received phmb 0.02% and divided into two groups according to the final visual acuity (va) va equal to o...

Background: Visual acuity, visual functioning, and vision related quality of life outcomes after cataract surgery were assessed in a population based study in a suburban area of Hong Kong. Methods: A cluster sampling design was used to select apartment buildings within housing estates for enumeration. All enumerated residents 60 years of age or over were invited for an eye examination and visua...

The authors report the visual outcome in 34 consecutive cases of treated acute central retinal artery obstruction. Visual acuity equal to or better than 6/30 was recovered in 35% of the cases. The presenting visual acuity and duration of visual impairment appear to correlate with visual prognosis.

PURPOSE To assess the prevalence of presenting visual impairment and refractive errors on the isolated island of Ta'u, American Samoa. METHODS Presenting visual acuity and refractive errors of 124 adults over 40 years of age (55 male and 69 female) were measured using the Snellen chart and an autorefractometer. This sample represented over 50% of the island's eligible population. RESULTS In...

purpose : to assess the results of intracorneal ring (icr) segments for treatment of patients with pellucid marginal degeneration (pmd) methods : in this prospective interventional case series study, eight eyes of 5 patients with pmd who were contact lens intolerant received one or two intacs (intacs, addition technology) segments. preoperative and postoperative evaluations included slit-lamp e...
