ArticleCan the preoperative fundus extorsion in infantile esotropia predict the development of postoperative inferior oblique overaction and dissociated vertical deviation?

Methods
The study protocol was approved by Institutional Review Board of Korea University Anam Hospital. Among the consecutive patients who had undergone surgery for infantile esotropia in Korea University Anam Hospital between January 2001 and December 2005, 40 patients whose fundus had been examined under general anesthesia before surgery were enrolled in this retrospective study. Before enrollment, oral informed consent was obtained from the parents of the patients. We confirmed the diagnosis of
Results
The mean preoperative and final postoperative distant and near angle size of esotropia, age at the time of surgery, and mean follow-up period after surgery in the 2 groups are shown in Table 1. There was no statistically significant difference in the characteristics of subjects between the 2 groups.
Table 2 shows the development of IOOA and DVD during the follow-up period after surgery. IOOA was present in 14 patients (66.7%) and DVD in 17 patients (80.9%) in the extorsion group, IOOA was
Discussion
Infantile esotropia is described as a congregation of large angle esotropia, IOOA, DVD, and amblyopia.7 When patients with infantile esotropia establish acceptable ocular alignment through early surgical intervention, they are more likely to develop fair binocular function.14, 15, 16 However, IOOA and DVD can develop even if patients achieve acceptable ocular alignment through surgery. Furthermore, the development of IOOA and DVD is hard to predict. Ing et al.17 stated that the development of

The effect of inferior oblique muscle weakening on horizontal alignment
2019, Journal of Current OphthalmologyCitation Excerpt :Furthermore, anterior and posterior ocular segments were examined by an experienced ophthalmologist using slit-lamp and indirect ophthalmoscope through dilated pupil. Color fundus photograph was also provided using a stereoscopic fundus camera (Visucam Pro NM; Carl Zeiss Meditec AG, Germany) for each eye to determine the fundus torsion if the patient agreed (there was no fundus torsion if the angle between horizontal line from the inferior one third of the optic disc and the line from this point to macula was less than 7° while the patient looked at a fixation target monocularly with a straight head).27 Eligible patients with IOOA≥+1 were operated on using IO recession, myectomy, or anteriorization.
Reliability of objective ocular torsion assessment using fundus photography in infantile esotropia
2019, Journal Francais d'OphtalmologieCitation Excerpt :Literature provides data on our understanding of objective ocular torsion, mainly in vertical strabismus, but still presents gaps in horizontal strabismus. For instance, objective ocular torsion can lead to subsequent vertical disorders in infantile esotropia [19]. It must therefore be considered and scored using a standardized procedure.
