“…In 2020, Zhang et al reported comparative results for the therapeutic effects of surgery following prism treatment versus surgery alone in cases of AACE. 19 Among the 46 cases, 26 underwent additional prism treatment before surgery (S+P group), and the remaining 20 cases were treated with surgery alone (S group), as in our report. Although no significant differences in motor success (≤10Δ) rate were observed between approaches at 12 months post-treatment (96% vs 90%, p > 0.05), the number of cases showing central near stereoacuity (≤60) "was significantly higher in the S +P group (85%) than in the S group (55%) at 12 months post-treatment.…”

“…18 Zhang et al also reported the results of therapeutic effects in 46 cases of AACE treated using surgery with preoperative prism treatment or surgery alone (Burian-Franceschetti type, n = 21; Bielschowsky type, n = 25). 19 They also recommended surgery following preoperative prism treatment based on the findings of improved binocular function and reduced recurrence rate. However, few studies have examined the benefits of prism adaptation test or preoperative prism treatment for AACE related to the excessive use of DDs.…”

“…One reason for such sensory outcomes may be differences in the type of AACE. Zhang et al reported 21 cases of Burian-Franceschetti type and 25 cases of Bielschowsky type, 19 and found that 19% of the S+P group and 15% of the S group were preoperatively positive for central near stereopsis. However, in our report, none of the cases in either group showed near stereopsis ≤60" at the initial visit.…”

To analyze surgical results of 32 cases with acute acquired comitant esotropia (AACE) related to prolonged use of digital devices (DDs). Patients and Methods: Medical records of cases with AACE related to prolonged use of DDs that had undergone surgery were retrospectively revised. Complete medical history and full ophthalmological examinations before and surgery were obtained for all cases. All cases also underwent neurological examinations using brain and orbital imaging. Motor success was considered as alignment within 10 prism diopters (Δ) at both near and distance. Sensory success was defined as stereopsis ≤60 arcsec. Nineteen cases (Group S) underwent surgery alone and 13 cases were treated with surgery and prism adaptation (Group S+P). Motor and sensory outcomes were compared between groups. Results: Mean age at first visit was 22.0 ± 9.0 years and mean daily use of DDs use was 6.3 ± 3.4 hours. Mean angle of preoperative alignment for distance and near were 26.5 ± 13.0Δ and 24.6 ± 16.4Δ, respectively. Surgery was performed at a mean of 23.3 ±3.5 years old and mean angle of alignment at final examination for distance and near were 5.8 ± 7.7Δ and 3.5 ± 5.7Δ, respectively. Final motor and sensory success rate were 84% and 53%, respectively. No significant differences in motor or sensory outcomes were evident between groups at initial or last visit. Conclusion: Favorable motor and sensory outcomes were achieved with surgical intervention with and without prism adaptation for AACT related to prolonged use of DDs.

“…When and how long a PAT is performed preoperatively differs from surgeon to surgeon and country to country [ 1 ]. Only recently, Zhang et al[ 18 ] compared the therapeutic effects of surgery following prism adaptation test versus surgery alone in Acute acquired comitant esotropia (AACE). They found no significant difference in success rate between the “prism plus surgery” group and “surgery” group 12 months postoperatively.…”

Prism adaptation test before strabismus surgery in patients with decompensated esophoria and decompensated microesotropia

Purpose To evaluate the effect of Prism adaptation test (PAT) on the angle of squint in decompensated esophoria (decEPH) and decompensated microesotropia (decMET). Methods In this single-center retrospective study we reviewed the medical records of patients with the diagnosis of decEPH or decMET, aged at least 12 years, who were treated by strabismus surgery for the first time. The maximum Angle of squint (AOS) for far (F) and near (N) fixation and PAT results before surgery, as well as AOS (F) and AOS (N) after surgery and results of binocular function tests were considered. PAT included wearing a prism based on the largest angle for over 60 min. Results 100 patients (mean age 37 ± 17 years) were included in the decEPH group, 82 patients (mean age 30 ± 13 years) in the decMET group. For decEPH, before surgery AOS was 25.5 ± 8.8 pdpt (F) and 23.5 ± 9.8 pdpt (N). During PAT the AOS increased significantly by 2.7 ± 4.3 to 28.2 ± 8.6 pdpt (F) and by 4.9 ± 4.5 to 28.3 ± 9.5 pdpt (N). Altogether, in 82% of decEPH patients AOS (F) and/ or AOS (N) in- or decreased by at least 3 pdpt. For decMET, before surgery AOS was 28.6 ± 10.8 pdpt for far (F) and 30.9 ± 11.8 pdpt for near fixation (N). During PAT the AOS increased significantly by 4.2 ± 5.8 to 32.5 ± 9.5 pdpt (F) and by 3.7 ± 6.1 to 34.4 ± 9.5 pdpt (N). Altogether, in 51% of decMET patients, AOS (F) and/ or AOS (N) increased by at least 10 pdpt, therefore more than 5° which would have been maximally expected from mictrotropia, or decreased by at least 3 pdpt. Conclusions The Prism adaptation test (PAT) showed remarkable changes in AOS in both decEPH and decMET. In patients with decEPH, the preoperative assessment of the “true AOS” under PAT reflects a pivotal requirement for successful strabismus surgery, as 82% had dose relevant angle changes ≥ 3 pdpt. For patients with decMET the preoperative prism adaptation test is especially of diagnostic value, but also 51% of decMET patients had changes in AOS beyond the expected microtropic angle (≥ 10 pdpt) or even a dose relevant angle decrease (≥ 3pdpt).

“…These findings are in accordance with Ela-Dalman et al (2006) who et al 2018). Zhang et al (2020) showed that surgery following PAT with a duration of 1 week to 3 months in participants with AACE (acute acquired comitant esotropia) leads to improved binocular function and reduced recurrence rate (Zhang et al 2020).…”

Purpose To evaluate the outcome in participants who underwent surgery for esophoria following one of three different methods of preoperative prism adaptation test (PAT). Methods This prospective, multicentre study was carried out at five eye departments from 2012 to 2019. 116 participants were included and allocated to three groups as per investigator choice: Group 1 ( n = 55) had a short prism adaptation period ranging from 1 to 5 hours during their visit at the clinic. Group 2 ( n = 36) underwent partial prism correction for at least 4 weeks before surgery. Group 3 ( n = 25) underwent full prism correction for at least 4 weeks before surgery. Motoric success was determined by postoperative angle of deviation (AOD), and sensoric success was evaluated with Lang and Bagolini striated lens test. Results A significant increase (p < 0.001) in AOD after PAT was observed in all groups, with no significant difference between groups (distance: p = 0.22; near: p = 0.31). Motoric and sensoric success was comparable between groups 3 months (p = 0.52; p = 0.55) and 1 year (p = 0.53; p = 0.29) after surgery. Prolonged prism adaptation ( n = 24) for more than 365 days was not associated with better results. Conclusion Our study indicates that the postoperative result is independent from the duration and amount (partial or full correction) of prism adaptation before surgery at least up to one year of follow‐up. Prolonged prism adaptation (>365 days) before surgery does not improve the results.
