The improving outcomes in intermittent exotropia study: outcomes at 2 years after diagnosis in an observational cohort

The improving outcomes in intermittent exotropia study: outcomes at 2 years after diagnosis in an observational cohort

....At follow-up, data were available for 371 children (81% of the original cohort). .... 0.5% (2/371) children developed constant exotropia. The surgically treated group was the only group with clinically significant improvements in angle or Newcastle Control Score. ... 8%... of those treated surgically required second procedures for overcorrection within 6 months of the initial procedure and at 6-month follow-up 21% (13) were overcorrected....

Comments: The folks in the UK have been doing some outstanding research in the area of strabismus surgery outcomes. I certainly congratulate them!! Unfortunately, most strabismus surgery outcomes really show that for many patients strabismus surgery may not be ready for prime time just yet and an alternate form of treatment should be considered. Optometric vision therapy should be one of the first treatment options considered prior to any surgical intervention.

Surgical intervention in childhood intermittent exotropia: current practice and clinical outcomes from an observational cohort study

Surgical intervention in childhood intermittent exotropia: current practice and clinical outcomes from an observational cohort study

.....35% of patients had excellent, 28% had fair and 37% had poor primary outcome. .... Satisfactory control was achieved in 65% of patients, while X(T) remained/recurred in 20%. Persistent over-correction occurred in 15% of children..... 40% of those initially over-corrected remained so by last postoperative assessment.....

Comments: 65% of the patients only achieved a fair or worse a poor outcome. 40% were over corrected ad remained that way. Before surgery is attempted, a consultation with a developmental optometrist is suggested. Go to http://covd.org to find such a doctor. DM

Severe complications of strabismus surgery

Severe complications of strabismus surgery


.... The most common reported complication was perforation of the globe..., followed by ... slipped muscle..., severe infection..., scleritis ..., and lost muscle..... Complications with the potential for a poor outcome are relatively common.....

Comments: Please note that most strabismus surgery most of the time does not result in one or more complications, however, these complications are often not discussed or glanced over by all involved. It is important for the medical consumer to do their due diligence and to be aware of unwanted side effects of medical intervention. DM

Exotropia in children with high hyperopia


Exotropia in children with high hyperopia

.....Children with high hyperopia and exotropia are likely to have developmental delay or other systemic diseases, amblyopia, and poor stereopsis. Treatment of high hyperopia in exotropic children with their full cycloplegic refraction can result in excellent alignment.....

Comments: The power of a pair of glasses! Many doctors (and patients) do not realize the therapeutic power of a pair of glasses. All too often we discount the "medcine in the glasses" and only consider the fashion sense (blue ones to go with blue outfits, green ones to go with green outfits) and cosmetic appeal. Use your refractive prescriptive powers to help your patients overcome vision problems above and beyond your typical approach to refractive care. DM
