“… 1 , 5 , 12 , 15 The forced duction test is more positive in the adherence syndrome than in the anti-elevation, where only a slight resistance is found in the temporal superior direction. 7 Finally, the deviation progressively worsens in the adherence syndrome and may occur later than in the anti-elevation (earlier onset and a stable deviation). 16 In our series of 6 cases were all diagnosed of adherence syndrome because surgery performed on the inferior oblique had been variable [in one case (no.…”

PurposeDescribe surgical treatment and results in a group of patients diagnosed and operated on of fat adherence syndrome following inferior oblique surgery.Patients, material and methodsRetrospective study of 6 cases diagnosed and treated of fat adherence syndrome following inferior oblique surgery. Mean age was 24.67 years (range, 5–41), 3 males, 5 unilateral and 1 bilateral. Mean vertical deviation was 16.16 pd (range, 4–25). Esotropia was associated in 4 cases, diplopia in other 2, and anomalous head posture in 3. A good outcome was considered when the final deviation was less than 10 pd, with mild limitation of elevation, without anomalous head posture, and a negative duction forced test.ResultsThe final vertical deviation was 6.83 pd (range, 0–14). A 2–4 mm inferior rectus recession was performed on 4 patients associated to an inferior oblique surgery/exploration. All patients were operated on once, except 1 case. A good outcome was achieved in 3 patients. Anomalous head posture was resolved in 2 of 3 cases. Diplopia resolved after surgery. Only one case achieved orthophoria. Mean evolution time was 34.83 months (range, 6–78).ConclusionIn the treatment of the fat adherence syndrome, an inferior rectus recession is recommended, associated to inferior oblique exploration or surgery. A good favorable outcome was only achieved in half of the cases with surgical treatment. Limitation of elevation could not be completely resolved in any of the patients.

“…Limiting surgery to the affected eye can risk uncovering a DVD in the fellow eye following unilateral surgery (Nabie et al 2007); this risk is reduced when a strong contralateral fixation preference is present (Bothun and Summers 2004) or VA in the affected eye is two or more lines lower than that of the other eye. Small but reportedly insignificant amounts of hypotropia may also occur in DVD (Bothun and Summers 2004) with some showing significant limitation of unilateral elevation (Cho et al 2006).

“…Mims and Wood (1989b) reported on a series of 61 children with inferior oblique overaction who underwent bilateral recession with antero-positioning procedures. If a truly unilateral DVD is present, then unilateral surgery has been recommended on the overacting inferior oblique muscle, but this may result in restricted elevation (Cho et al 2006) (antielevation syndrome). Kratz et al (1989) also reported on the effect of ATIO tendon in DVD.…”

Кроме того, выявляется выраженная кривошея вследствие развития глазного тортиколлиса и положительный тест Бильшовского [2][3][4][5].…”

The purposeto evaluate the effectiveness of dosing procedures for the degree of anterior transposition of the lower oblique muscle in the surgical treatment of its secondary hyperfunction of varying severity using modern methods of ophthalmological examination.Patients and methods. Between January 2013 and June 2017, 31 children (31 eyes) aged 3 to 17 years with vertical strabismus due to unilateral insufficiency of the superior oblique muscle were monitored. Depending on the magnitude of the vertical deviation in the adduction on the paretic eye measured in degrees by the Hirschberg method in the head rotation position, all patients were divided into two groups: group 1 — 12 children (12 eyes) (no more than 7° according to Hirschberg); group 2 — 19 patients (19 eyes) (more than 7° according to Hirschberg). Surgical treatment of hypertrophy was performed in all patients in both groups. Weakened the lower oblique muscle by its dosed front transposition. The degree of anterior transposition of the lower oblique muscle depended on the magnitude of the angle of vertical deviation.Results. The surgical intervention on the lower oblique muscle was performed in all patients in full. Hypertrophy in the primary position of the gaze in group 1 was completely eliminated in 11 eyes (91.7%), in group 2 — in 17 eyes (89.5%). The residual vertical angle, equal to 3 ° according to Hirschberg, in group 1 was detected in 1 eye (8.3%), in group 2 — in the 2 eyes (10.5%). Hypertrophy in adduction in group 1 was completely eliminated in 10 eyes (83.3%), in group 2 — in 17 eyes (89.5%). The residual vertical angle of 3° in Hirschberg’s group 1 was detected in 2 eyes (16.7%), in group 2 — in 2 eyes (10.5%).The conclusion. Application of the technology of dosed front transposition of the lower oblique muscle in the surgical treatment of its secondary hyperfunction will significantly improve the effectiveness and safety of treatment and reduce the risk of complications, shorten the duration of surgery and anesthesia in child. The developed method of dosing the degree of anterior transposition allows to perform this operation monolaterally, without fear of developing secondary hyperfunction of the lower oblique muscle in the pair eye.
