There their increased intelligence and understanding capability. But

There were certain
limitations of this study. The correlation of these individual signs with CISS
and ABS was not done. The score level might have been different for these
individual signs though they all fall upon one sign CI category. Besides, we
also did not measure the CISS score in accordance to the severity of the signs.
For near exophoria, cut-off points for mild were ? 8 exo (?1SD), moderate >8
exo to <13 exo (>1SD to < 2SD), and severe ?13 exo (?2SD). For PFV, cut-off points for mild were ? 15? (? 1SD), moderate >7? to <15? (>1SD to <2SD), and severe ?7? (?2SD). For NPC, the cut-off points were mild 6 cm to <9 cm (?1SD to <2SD), moderate 9 cm to <12 cm (?2SD to <3SD), and severe ?12 cm (?3SD) (Bade et al, 2013). We could have encountered some differences in both CISS and ABS scores if we also had taken severity of signs of CI into account. The results were fully dependent upon the responses given by children and parents. So there might be biasness from each groups. The responses from children of older age group may be reliable due to their increased intelligence and understanding capability. But the responses given by younger age group may not be reliable. The parents were not allowed to consult with children during the survey. So the responses in ABS score about the child's behavior may not resemble the true behavior for those children whose parents do not stay with them all the time. We didn't investigate for the presence of ADHD in children. Childern with ADHD scored higher in ABS than those without ADHD.(1,6). The symptoms like inability to concentrate during reading and slow reading resemble ADHD behaviors (rouse 2009).After diagnosing the children with CI, home based therapy was given to them for 6 weeks after which they were asked to follow up. But we did not carry out follow up study. The signs, symptoms as well as ABS scores might have been decreased with the appropriate treatment.(BOrsting 2013). . The decrease in these symptoms following Office Based Vergence and Accomodative Therapy (OBVAT) suggest that those symptoms were due to CI and not due to ADHD.   Conclusion Convergence insufficiency might be the cause of adverse behaviors of children during their academic work as they scored significantly higher on ABS as compared to the children with normal binocular vision. The greater the number of CI signs, the greater is the score on CISS and ABS. These behaviors in children with CI can be reduced by providing them with vision therapies, and thus improving their school performance.
