RESUMO
People with multiple sclerosis (pwMS) report many different visual complaints, but not all of them are well understood. Decline in visual, visuoperceptual and cognitive functions do occur in pwMS, but it is unclear to what extend those help us understand visual complaints. The purpose of this cross-sectional study was to explore the relation between visual complaints and decline in visual, visuoperceptual and cognitive functions, to optimize care for pwMS. Visual, visuoperceptual and cognitive functions of 68 pwMS with visual complaints and 37 pwMS with no or minimal visual complaints were assessed. The frequency of functional decline was compared between the two groups and correlations were calculated between visual complaints and the assessed functions. Decline in several functions occurred more frequently in pwMS with visual complaints. Visual complaints may be an indication of declined visual or cognitive functioning. However, as most correlations were not significant or weak, we cannot infer that visual complaints are directly related to functions. The relationship may be indirect and more complex. Future research could focus on the overarching cognitive capacity that may contribute to visual complaints. Further research into these and other explanations for visual complaints could help us to provide appropriate care for pwMS.

AIM: To determine the incidence of visual impairment (VI) caused by retinopathy of prematurity (ROP) and concomitant disabilities in preterm neonates born between 2000 and 2009 in the Netherlands. METHODS: Data were retrieved from the Dutch institutes for the visually impaired. They were compared with similar Dutch studies conducted in 1975-1987, 1986-1994 and 1994-2000. RESULTS: Records of 42 infants with VI due to ROP were included. A gradual decrease of gestational age and birthweight but an increase of duration of artificial ventilation, supplemental oxygen administration, bronchopulmonary dysplasia, developmental delay and behavioural abnormalities was found. Compared with the previous study (1994-2000), significantly fewer children were visually impaired due to ROP (1.84 per 100,000 live births/year vs 3.93 per 100,000 live births/year, p=0.000), the incidence of complete blindness decreased from 27.5% to 7.1% (p < 0.05) and more children were treated (66.7% vs 56.9%, NS). The incidence of concomitant disabilities was high and did not differ greatly from the previous study. CONCLUSION: This was a retrospective study showing a significant decrease in VI due to ROP in the Netherlands. Changes in neonatal care practices did not result in a decrease in the incidence of concomitant disabilities. More children were treated for ROP, but 33% were not treated.

OBJECTIVE: To compare the effectiveness of two 45 degrees photographic fields per eye in the screening for diabetic retinopathy with the routine ophthalmologist's examination and to study the effectiveness of visual acuity measurement in the detection of diabetic macular edema. RESEARCH DESIGN AND METHODS: Type 1 and 2 diabetic patients without a known history of more than minimal retinopathy (n = 469) had a routine examination by an ophthalmologist, including visual acuity measurement, indirect retinoscopy, and biomicroscopy. At the same time, two-field nonstereoscopic retinal photographs were made of both eyes and assessed in a masked fashion by a retinal specialist. The results were compared. RESULTS: The prevalence was 4.3% for vision-threatening retinopathy and 24% for any retinopathy. The sensitivity of two-field photography in identifying diabetic patients with sight-threatening retinopathy was 95% (specificity 99%) and sensitivity for detecting any retinopathy was 83% (specificity 88%). The percentage of referrals to an ophthalmologist was 6.2%. All patients with macular edema detected by biomicroscopy were classified as having vision-threatening retinopathy on the photographs. CONCLUSIONS: Two-field retinal photography is a promising alternative to the routine ophthalmologist's examination in the screening for diabetic retinopathy. Visual acuity measurement is not a sensitive tool for the detection of macular edema. Screening for diabetic retinopathy using two-field retinal photography is feasible in a primary care setting and can substantially lower the number of ophthalmic referrals.
