Impact of Simulated Hyperopia on Academic-Related Performance in Children.

Impact of Simulated Hyperopia on Academic-Related Performance in Children.

"...A relatively low level of simulated bilateral hyperopia impaired children's performance on a range of academic-related outcome measures, with sustained near work further exacerbating this effect. ..."


Comments: Ever since I was in optometry school (dinosaurs still roamed the earth at that time), optometrists have clinically known that even low amounts of hyperopia could adversely effect academic performance because of its neurological interactions with accommodation and vergence. The evidence continues to accumulate that hyperopia and vision function effects school performance. 


Vision screening often misses these vision related learning problems. ONLY a full, comprehensive eye and vision examination will diagnose these problems. Our children deserve full examinations and not just vision screenings.

Research and comments from past MainosMemos blog posts:

Effectiveness of screening systematic review  http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2731050/pdf/1471-2415-9-3.pdf

Population based preschool vision screening programmes cannot be sufficiently assessed by the literature currently available. However, it is most likely that the present systematic review contains the most detailed description of the main limitations in current available literature evaluating these programmes. Therefore, future research work should be guided by the findings of this publication.

Comments: I don't get it...this paper says there is NO evidence that consistently supports vision screening....why isn't optometry and InfantSee shouting this from the roof tops?DM (Looks like they are!!!)

Evidence-based medicine: the value of vision screening.  http://www.ncbi.nlm.nih.gov/pubmed/21061880

This paper answers a couple of questions about the value of vision screening. The questions were:

(1) Is vision valuable (an inherent good)?; (1) yes 
(2) Is screening effective (finding amblyopia)?; (2) no
(3) Is amblyopia detection beneficial? (3) economic productive values are likely very high, with returns of investment on the order of 10:1,
