At postoperative 1 month, the patient was orthophoric and there were no pathologic symptoms besides the irregular pupil.
The patient was orthophoric in primary position and there was -1 limitation in right eye movement (Figures 1-4).
Infants of 4 months should have an orthophoric
Table 5 shows the number of patients in the successful and unsuccessful surgery groups who were orthophoric 1 week and 6 months post surgery.
11,16,24-26) Moreover, at the 6-month post-surgery follow-up, we observed that there were 2 measures that predicted success orthophoric and residual exodeviation [less than or equal to] 10 PD.
Of the remaining 190 patients, cover test revealed 86% to be orthophoric
, 13% to be exophoric and only 1% were esophoric.
Her left eye could not fixate any objects when the right eye was occluded but she was orthophoric
on Hirschberg when both eyes were open.
Surely the argument for not specifying the PD on a prescription should centre on the fact that, although it may be a constant value for an orthophoric
patient viewing a distant object (differences between ruler measurements and pupillometer measurements notwithstanding), the measured PD is not necessarily the correct specification for the centration distance.
For example, some patients may be orthophoric
at their reading distance (eg, 40cm), or even esophoric, and yet not be able to converge to 10cm.
During normal eye movements, small vergence errors occur which mean that, even in an orthophoric
patient, adequate fusional reserves are required to maintain comfortable fusion.
