purpose: to present a case of spontaneous resolution of essential esotropia case report: a 22-month-old girl presented with eye deviation since the age of 4 month. in the first examination, visual acuity of both eyes was c+s+m+. the patient had 35 prism diopters of alternative esotropia in primary position and also bilateral inferior oblique overaction (iooa). there was no significant refractiv...

PURPOSE Recurrence of inferior oblique overaction (IOOA) after recession or anterior transposition of the inferior oblique (IO) muscles is a common problem. We have been treating such cases by nasal myectomy of the IO, where a segment of approximately 5 mm is removed from the nasal portion, leaving the temporal portion of the IO with its insertion and its ancillary origin, the neurofibrovascula...

A full-term female baby was diagnosed as having Apert syndrome with craniosynostosis, hypertelorism, syndactyly, polydactyly, and cleft plate. At her first ophthalmic visit at 8 months old, she was noted to have bilateral exophthalmos with epiblepharon on her lower lids, exotropia, and right inferior oblique muscle overaction (IOOA) and manifested right dissociated vertical deviation (DVD). The...

INTRODUCTION Inferior oblique overaction (IOOA) can be primary or secondary, isolated or combined to other types of horizontal deviation, mostly with esotropias. Surgical weakening of IOOA means several techniques like; recession, myotomy, myectomy, anteroposition etc. GOALS we analyzed the effect of inferior oblique muscle surgical weakening comparing two groups of patients with primary hype...

fhe X-ray diffraction patterns of whole chromatin in dilute solution and of isolated repeat units are essentially the same. Recent work has established a repeating structure for ttre ctrromatin of eukaryotes. One repeat comprises two each of the four main histones surrounded by about 200 base gairs of DNA, forming a beadlike object about IOOA in diameter. Such beads occur in close apposition al...

purpose: to study the prevalence and characteristics of accommodative esotropia (aet). methods: in a descriptive analytic study records of all patients referred from 1383 to 1388 to the strabismus clinic at nikookari eye center were reviewed and demographic data such as age, gender, refractive error, type of aet, mean deviation and amblyopia were analyzed. results: a total of 2,146 patients wer...

PURPOSE To report antielevation syndrome with restriction of elevation on abduction in the operated eye and overaction (OA) of the inferior oblique muscle (IO) of the contralateral eye after unilateral IO anteriorization (AT). METHODS Medical records were reviewed retrospectively in 8 of 24 patients who underwent unilateral IOAT. Four patients were referred from other hospitals after the same...
