'Does Correction of Strabismus Improve Quality of Life in Children with Autism Spectrum Disorder?' went the title of the paper by Pinar Ozer and colleagues . Yes, it may very well do was the answer (but with certain caveats and the requirement for a lot more research in this area).
Strabismus, a condition where the eyes don't line up in the same direction, can sometime have some quite noticeable effects on a person's vision and indeed, has been linked to various other non-vision related symptoms and outcomes.
Ozer et al looked to identify "the impact of optical or surgical correction of the strabismus on the child using a questionnaire for parents." The published research of this team has been previously discussed on this blog (see here) with ophthalmic findings in mind, and the requirement for quite a few more resources to be put into eye examinations when autism is diagnosed (see here). This time around they were discussing what happens when such eye issues are resolved.
I'm not completely convinced that the Ozer findings this time around reporting 'significant improvements' in areas of "psychosocial interactions" is as it stands, a methodologically firm finding just pertinent to autism. Although no expert on strabismus, from what I gather, the 'cosmetic' side of the condition can have some far-reaching effects on 'psychosocial' functions. I daresay that such effects would be just as prevalent in autism as they are in the general population and hence, correction would likely have similar outcomes.
I am more open to the idea that if strabismus is affecting vision, as in causing something like blurred or double vision, correction of the issue may in some cases have some important 'effects' in relation to autism. Accepting that structural issues with the eye are not necessarily the same as or causative of visual perceptual issues that seem to crop up quite often in the autism research arena, it is not outside the realms of possibility that something like strabismus could be part and parcel of visual effects for some people.
I suppose to reiterate, screening for structural eye/vision issues when it comes to autism remains a pretty important area.
To close, karate gradings for one of my brood today and this is what they will be attempting...
