dilated pupils, we assumed that 7 applications of atropine were enough to<br />
produce complete cycloplegia. Ideally, a clinician should routinely perform<br />
dynamic retinoscopy to confirm complete cycloplegia for every patient<br />
especially if less potent cycloplegic agent is used. In this study, atropine was<br />
not associated with any severe systemic side effects.<br />
In one patient who had esotropia with nonaccommodative convergence<br />
excess, the esotropia persisted under cycloplegia. The esotropia persisted for<br />
smaller as well as larger size of the accommodative targets and on the torch<br />
light evaluation. It was evident that atropinic cycloplegia was unable to abolish<br />
excessive convergence in that patient. It was less likely to be due to incomplete<br />
cycloplegia because, in this patient, we had confirmed complete cycloplegia<br />
using dynamic retinoscopy and dynamic autorefractometry. 6<br />
In conclusion, measurement of ocular deviation under cycloplegia can<br />
be helpful to differentiate the accommodative component from the nonaccommodative<br />
component in patients with esotropia and hyperopia. In this<br />
study we could reliably differentiate the patients with esotropia and hyperopia<br />
who would achieve orthotropia by full refractive correction alone (59.1%). An<br />
ophthalmologist can inform the parents accordingly. Of the remaining 40.9%,<br />
how many would be controlled by the fusional divergence or will need prisms<br />
or will need a squint surgery can be known from the follow up. The effect of<br />
other cycloplegic agents and the utility of measurement of ocular deviation<br />
under cycloplegia in accommodative esotropes pursuing a refractive surgery<br />
need further studies.<br />
