“…[1–5] However, wide variations have been reported in the measured results of the disc foveal angle (DFA) which is formed at the optic disc center between the horizontal meridian and the line joining the center of disc and foveal center. [23] DFA is indicative of the cycloposition of the eyes. The aim of the study was to evaluate the DFA and to find its correlation with possible influencing factors in children between 5–15 years of age.…”

Cycloposition has been measured by various methods; however, fundus photography is the most reliable method to evaluate the torsion objectively. We did a prospective study to find out the disc foveal angle (DFA) and its variation in children without squint. We included 210 eyes of 105 children between the ages of 5-15 years. DFA was calculated using standard technique after taking a fundus photograph. The cycloplegic refraction was done and compared. The mean age was 10.6 ± 2.5 years. Mean DFA in right eye (RE) was 6.49 ± 3.25° (0-13°) and in left eye (LE) was 5.80 ± 3.29° (0-12°). The difference between the RE and LE was statistically not significant (P=0.131) (mean 1.15 ±1.39°). Mean DFA in emmetropic children was 6.1° ± 3.4° (n=112 eyes). DFA varies widely in children. The difference observed in DFA measurement for eyes with various refractive errors were compared with DFA measurements for emmetropic eyes.

Importance: Recognition of sagging eye syndrome (SES) as the cause of chronic or acute acquired diplopia may avert neurologic evaluation and imaging in most cases.Objectives: To determine whether SES results from inferior shift of lateral rectus (LR) extraocular muscle (EOM) pulleys and to investigate anatomic correlates of strabismus in SES. Design and Setting:We used magnetic resonance imaging to evaluate rectus EOMs, pulleys, and the LRsuperior rectus (SR) band ligament at an eye institute.Participants: Patients with acquired diplopia suspected of having SES. We studied 56 orbits of 11 men and 17 women (mean [SD] age of 69.4 [11.9] years) clinically diagnosed with SES. Data were obtained from 25 orbits of 14 control participants age-matched to SES and from 52 orbits of 28 younger controls (23 [4.6] years).Main Outcome Measures: Rectus pulley locations compared with age-matched norms and lengths of the LR-SR band ligament and rectus EOMs. Data were correlated with facial features, binocular alignment, and fundus torsion.Results: Patients with SES commonly exhibited blepharoptosis and superior sulcus defect. Significant inferolateral LR pulley displacement was confirmed in SES, but the spectrum of abnormalities was extended to peripheral displacement of all other rectus pulleys and lateral displacement of the inferior rectus pulley, with elongation of rectus EOMs (PϽ .001). Symmetrical LR sag was associated with divergence paralysis esotropia and asymmetrical LR sag greater than 1 mm with cyclovertical strabismus. The LR-SR band was ruptured in 91% of patients with SES.Conclusions and Relevance: Widespread rectus pulley displacement and EOM elongation, associated with LR-SR band rupture, causes acquired vertical and horizontal strabismus. Small-angle esotropia or hypertropia may result from common involutional changes in EOMs and orbital connective tissues that may be suspected from features evident on external examination.

“…This is unlikely to be caused by a bias in the measured foveal depression angles because they varied from À28 to À158 across individuals in our study, very similar to results of other studies. 9,13,37,38 Other possible sources attributed to the raphe angle variance include subjects' head position and measurement errors of identifying the disc center, fovea, and raphe. Future studies are warranted to investigate the roles of these sources of variance on the raphe angle measurement.…”
