Outcomes of Medial Rectus Recession With Adjustable Suture in Acute Concomitant Esotropia of Adulthood.

To review and analyze the surgical outcomes of bilateral medial rectus recession with adjustable suture in acute concomitant esotropia of adulthood (ACEA). The charts of all adults diagnosed as having ACEA between 2004 and 2017 were reviewed. Best corrected visual acuity, refractive error, ocular alignment measured in prism diopters (PD), and stereopsis were examined at presentation, 1 day postoperatively, and final follow-up visit (median: 10 months; range: 4 to 144 months). All patients underwent bilateral medial rectus recession using adjustable suture surgery and topical anesthesia. Statistical analysis was used to calculate surgical dose-responses and to study possible correlations with clinical parameters. Fifteen patients diagnosed as having ACEA were included. The mean age was 39.2 ± 10.7 years, and the mean refractive errors in the right and left eyes were -3.97 ± 2.87 and -3.60 ± 2.74 diopters (D), respectively. Average esotropia deviations at near and distance were 22.7 ± 7.2 and 23.0 ± 7.5 PD. All patients improved with medial rectus recession (mean: 12.0 ± 2.2 mm) with a final mean deviation of 0.7 ± 1.8 PD. The mean dose-responses at 1 day postoperatively and final visit were 1.86 ± 0.58 and 1.83 ± 0.43 PD/mm, respectively. There was a significant positive correlation between surgical dose-responses at 1 day postoperatively and final visit and preoperative deviation (R2 = 0.55; P < .001; R2 = 0.66; P < .001), whereas there were no significant correlations with age, sex, refractive error, BCVA, or stereopsis (all P > .05). Good postoperative and final outcomes are achieved with large medial rectus recessions in ACEA. A larger dose-response can be expected in large preoperative deviations, independent of other clinical and ocular parameters. [J Pediatr Ophthalmol Strabismus. 2019;56(2):101-106.].

Observation of effect of surgical correction of strabismus with adjustable suture in treating acute comitant esotropia

Objective To observe the efficiency of surgical correction of strabismus with adjustable suture in treating acute concomitant esotropia. Methods 12 acute concomitant esotropia cases were treated by surgical correction of strabismus with adjustable suture and synoptophore training for 15 days postoperatively. Results Postoperative diplopia: 11 cases regained binocular single vision without diplopia at the near or far distance. 1 case remained 8 prism diopters(PD) esotropia postoperatively, with no diplopia within 1 meter and diplopia alleviated significantly beyond 1 meter. Conclusion The effect of surgical correction of strabismus with adjustable suture in treating acute concomitant esotropia is satisfactory. Key words: acute concomitant esotropia; surgical correction of strabismus; adjustable suture

Endotropía comitante aguda y ambliopía histéricas

The authors present the case of a 26-year-old woman, in her 29th week of pregnancy, who developed intermittent esotropia and diplopia. Six months later, the process was associated with visual loss and an accommodative spasm which did not improve with cycloplegia and refraction. The symptoms remained unchanged two years later. Acute concomitant esotropia may have no obvious underlying cause, but it has been associated with disruption of fusion, myopia, neurological problems and decompensation of a pre-existing phoria or monofixation syndrome. A physical or emotional debilitating illness may precede the onset of the problem. In our case, a neurologic origin was excluded and a diagnosis of hysterical neurosis and acute concomitant esotropia with hysterical amblyopia or functional visual loss was established.

Acute concomitant esotropia of adulthood

Purpose To identify the characteristics of adult patients who develop acute concomitant esotropia of adulthood. Design Retrospective noncomparative case series. Participants Ten patients were included in this study. Intervention The charts of all adults with acute-onset concomitant esotropia who were examined at our institute between 1990 and 1997 were reviewed, and those who had developed the syndrome when they were older than the age of 16 years were included in this study. All participants underwent a complete ocular and physical examination, including brain and orbital computed tomography. Main outcome measures Angle of esotropia, measured by the prism and cover test. Results The mean age ± standard deviation at the time of the ocular and physical examination was 38 ± 18.6 years (range, 18–70 years). The mean myopic error was −4.1 ± 3.2 diopters (range, +2.0 to −8.5 diopters). Nine of the 10 patients were myopic. The mean angle of esotropia was 33.8 ± 14.7 prism diopters (range, 18–60 prism diopters). The mean period of follow-up was 2.2 ± 1.0 years (range, 1–4 years). After surgery, all patients were orthophoric or minimally esophoric, and in all of them, stereoacuity (measured by the Titmus stereofly test) was 40 arc seconds. Conclusions In a well-defined group of adult patients with acute-onset concomitant esotropia, almost all were myopic, and all regained normal stereopsis after surgery. Acute concomitant esotropia of adulthood should probably be classified as a distinct subgroup of acute-onset esotropia.

Visual function deficits in children.

In the past year, new work on sensory testing in preverbal infants has expanded our knowledge in three areas: 1) visual acuity testing in infants in varying levels of illumination; 2) visual evoked cortical potential-evidence for binocular function in infantile esotropia; and 3) a new time-efficient method to evaluate color vision in newborns and infants. A newly reported sequel to loss of binocularity is the development of A and V pattern strabismus. In another study, loss of fusion, as with acute concomitant esotropia, was shown to be a sign of serious intracranial disease. Regarding motor visual function deficits, new treatments of infantile esotropia syndrome and nystagmus with botulinum toxin type A are presented. Regarding social issues, visual function deficit of abused children and infants born to drug-abusing mothers are presented as a timely reminder that child abuse is still an enormous social problem, and that the visual system is far from exempt from damage.
