Vision screening in older adults on dialysis: do nephrology nurses have a role?

Undetected vision loss commonly occurs in older adults adding undue stress to those on dialysis. Poor vision is associated with increased risk of falls and decreased quality of life. Common visual impairments--presbyopia, cataracts, age-related macular degeneration, glaucoma, and diabetic retinopathy--often are detectable by visual acuity testing. Using various methods of visual acuity testing, nephrology nurses can perform vision testing quickly and inexpensively. Other nursing interventions also can improve eyesight.

Vision screening in junior schools.

A prospective study of routine school vision tests in 1809 children aged 8 and 10 y was undertaken in schools in the Cambridge Health District over two years (1988-1990) to establish whether a significant number of defects of vision were detected. Although the visual acuity of 31% of children who had an abnormal test was recorded as abnormal, most abnormalities were minimal. Only 15 (0.83%) had newly diagnosed problems requiring treatment. Almost all children with marked visual abnormalities had already been detected before school entry, at the 5 y school vision test or on another occasion. Near vision testing did not identify any previously undiagnosed child with significant defects who did not also have distant vision abnormalities. Satisfactory colour vision test results had been recorded for most children at the 5 y school entry vision test. These data do not justify the continued use of routine screening in junior schools.

Referral rates for a functional vision screening among a large cosmopolitan sample of Australian children.

The aim of this study was to investigate the incidence of functional vision problems in a large unselected cosmopolitan population of primary school-age children and to investigate whether constant clinical criteria for functional vision problems would be implemented by the practitioners involved in the screening. Refractive errors, near point of convergence, stereopsis, strabismus, heterophoria and accommodative facility were assessed for 2697 children (3-12 years) of varying racial backgrounds living in Australia. The spherical component of the refractive error ranged from -7.75 to +9.50 D (mean +0.54 D, +/-0.79) with a distribution skewed towards hypermetropia; astigmatism ranged from 0 to 4.25 D (mean -0.16 D, +/-0.35). There was a trend towards less hypermetropia and slightly more astigmatism with age. Mean near point of convergence was 5.4+/-2.9 cm, heterophoria at far and near was 0.12+/-1.58delta exophoria and 1.05+/-2.53delta exophoria, respectively, 0.55% of children exhibited vertical phoria at near >0.5delta, accommodative facility ranged from 0 to 24 cycles per minute (cpm) (mean 11.2 cpm, +/-3.7), stereopsis varied from 20 to 800 s (") of arc with 50% of children having 40" or better. The prevalence of strabismus was particularly low (0.3%). Twenty percent of the children were referred for further assessment based on criteria of one or more of: stereopsis >70", accommodative facility <8 cpm, near point of convergence (NPC) >9 cm, near exophoria >10delta or near esophoria >5delta, shift in eso or exophoria > or = 4delta between distance and near, astigmatism > or = 1 D, myopia more than -0.75 D, or hyperopia >+1.50 D. Post-hoc analysis of the record cards seeking the reason for further assessment indicates that referrals appear to have been based upon clinical intuition rather than on a set number of borderline or unsatisfactory results.

Colour vision screening in glaucoma: the Tritan Album and other simple tests.

Results from simple colour vision tests used for the detection of the Type III colour vision deficiency in glaucoma and ocular hypertension are presented. We assessed 49 patients with primary open angle glaucoma, 16 ocular hypertensives, 54 age matched normals and 50 young normal observers using six established tests and the recently introduced Tritan Album. This test was introduced specifically for acquired colour vision deficiencies. Results show in general that individual tests have low sensitivity and poor screening efficiency. The best screening efficiency was achieved by the City University Colour Vision Test and the AO HRR plate test, no acquired tritan defects were identified by the Farnsworth F2 plate, and the Tritan Album had very low sensitivity (the lowest excluding the F2 plate). Best results were obtained from a combination of City University and HRR test scores and this combination could provide useful additional data on colour vision in a glaucoma screening programme.
