Slanted medial rectus recession is effective in the treatment of convergence excess esotropia.

Slanted medial rectus recession is effective in the treatment of convergence excess esotropia.


"...Near-distance disparity of 10 PD or less was obtained in 14 patients after surgery (87.5%), except 2 patients who had 16 PD of disparity. The authors did not encounter overcorrection except in 1 patient in whom minimal exophoria at distance and near with the glasses was observed and reduced the prescription....."

Comment: The outcome numbers for this study tend to be a bit better than the 20-30% fail rate for other papers that look at strabismus surgery outcome. I wonder what the success rate would be if these patients had vision therapy prior to and after surgery? Maybe one day this will be the standard approach by all to ensure better outcomes. DM

Soccer is hard on the brain: heading the ball may impair the player's memory

Soccer is hard on the brain: heading the ball may impair the player's memory


"...Heading the ball is not good for the brain. Even when the heads of soccer players are exposed to collisions or blows too frequently, these slight, but recurring concussions result in attention deficit in the long term. This is suggested by a Croatian study which was presented at the 1st Congress of the European Academy of Neurology (EAN) in Berlin..."

Quantifying naturalistic social gaze in fragile X syndrome using a novel eye tracking paradigm.

Quantifying naturalistic social gaze in fragile X syndrome using a novel eye tracking paradigm.

"....A hallmark behavioral feature of fragile X syndrome (FXS) is the propensity for individuals with the syndrome to exhibit significant impairments in social gaze during interactions with others. ....To improve upon previous studies, we used a customized eye tracking configuration to quantify the social gaze..... Results showed that participants with FXS spent significantly less time looking at the face and had shorter episodes (and longer inter-episodes) of social gaze than controls. Regression analyses indicated that communication ability predicted higher levels of social gaze in individuals with FXS, but not in controls. Conversely, degree of autistic symptoms predicted lower levels of social gaze in controls, but not in individuals with FXS. Taken together, these data indicate that naturalistic social gaze in FXS can be measured objectively using existing eye tracking technology during face-to-face social interactions. Given that impairments in social gaze were specific to FXS, this paradigm could be employed as an objective and ecologically valid outcome measure in ongoing Phase II/Phase III clinical trials of FXS-specific interventions.....

Enhanced Visual Search in Infancy Predicts Emerging Autism Symptoms.

Enhanced Visual Search in Infancy Predicts Emerging Autism Symptoms.

"....Enhanced visual search performance at 9 months predicted a higher level of autism symptoms at 15 months and at 2 years. Infant perceptual atypicalities are thus intrinsically linked to the emerging autism phenotype...."
