Miopexia supra-ecuatorial del recto lateral en el tratamiento del síndrome «sagging/heavy eye» miópico / Supraequatorial displacement with lateral rectus myopexy for treatment of myopic sagging/heavy eye

Objetivo Describir los resultados de sujetos con síndrome «sagging/heavy eye miópico» operados mediante la miopexia supraecuatorial del recto lateral. Método Estudio retrospectivo de 9 casos entre 2017-2023. Se analizaron desviación horizontal, vertical, ambliopía, diplopía, ducciones, torsión, pruebas sensoriales antes y después de la cirugía, patología macular y resonancia magnética orbitaria. El tratamiento se consideró exitoso cuando desaparecía o mejoraba la diplopía y una desviación vertical≤5 dioptrías prismáticas (Dp) al final del seguimiento. Resultados La edad media (DE) fue: 62,11 (4,6) años (100% mujeres). El 88,88% presentaba diplopía. La hipotropía media preoperatoria fue: 11,33Dp (DE 3,16), y la desviación vertical final 3,44Dp (DE 3,05). Tras la cirugía, la hipotropía se invirtió en un caso, quedó subcorregida en 5 y se alcanzó ortoforia en otros 3. La técnica se asoció a la cirugía de otro músculo recto en 4 sujetos. El tiempo medio de seguimiento posquirúrgico fue de 34 meses (DE 34,62). Seis de las 9 pacientes quedaron con una desviación vertical≤5Dp. En 3 pacientes se consiguió eliminar totalmente la diplopía, mientras que en 5 quedó intermitente (3 con patología macular) Conclusión En el tratamiento del «sagging/heavy eye miópico», el supradesplazamiento ecuatorial con miopexia del recto lateral constituye una opción terapéutica si la hipotropía es menor de 12Dp o la técnica de Yokoyama no está indicada. Se obtuvo un buen resultado en más de la mitad de los casos, suprimiéndose totalmente la diplopía en 3 y quedando en otros 5 de forma intermitente (AU)

Purpose To describe the outcome of the patients diagnosed of sagging/heavy eye associated to myopia, that were operated on with the supra-equatorial displacement with lateral rectus myopexy. Methods A retrospective study of 9 cases between 2017 and 2023. The following data were analyzed: horizontal and vertical deviation, diplopia, amblyopia, ductions, ocular torsion, sensorial test, macular pathology, and the orbital magnetic resonance. Treatment was considered successful if the diplopia was improved or eliminated and a final vertical deviation≤5prism diopters (PD). Results The mean age (SD) was: 62.11 (4.6) years (100% women). A total of 88.88% presented diplopia. The mean preoperative hypotropia was: 11.33PD (SD 3.16), and the mean final VD 3.44PD (SD 3.05). After surgery, the hypotropia was overcorrected in one case, under corrected in 5, and orthophoria was achieved in another 3. The technique was associated with surgery of another rectus muscle in 4 subjects. The mean follow-up time after surgery was 34 months (SD 34.62). Six of the 9 patients improved with a vertical deviation≤5PD. In 3 patients, the diplopia was eliminated, while in 5 it remained intermittent (3 with macular pathology). Conclusion Supra-equatorial displacement with lateral rectus myopexy for treatment of myopic sagging/heavy eye is a therapeutic option if hypotropia is less than 12PD or the Yokoyama technique is not indicated. A good result was obtained in most cases, although diplopia could only be totally suppressed in three, and another five remained intermittent (AU)

Insuficiencia de convergencia con diplopía: tratamiento quirúrgico en adultos / Convergence insufficiency with diplopia: Surgical treatment in adults

Propósito Estudiar los resultados del mini plegamiento central del recto medial (RM) en las insuficiencias de convergencia de adultos con diplopía. Método Análisis retrospectivo de una muestra de 9 casos (7 mujeres). Se recogieron los datos de la dosis de plegamiento del RM, la hipercorrección inmediata posquirúrgica y al final del seguimiento, la desviación final de cerca y de lejos, la diplopía y el tiempo de seguimiento desde la cirugía. Se consideró buen resultado la desaparición de la diplopía, mejoría de los síntomas y una exotropía final de cerca ≤8dioptrías prismáticas (dp). Resultados Se realizó un mini-plegamiento central del RM en 9 pacientes (8 unilaterales). Edad media: 58,66 años (SD: 21,39). La media de la desviación preoperatoria de cerca fue de 16,22 (±2,99) dp y de lejos 6,88 (±4) dp. Se registró hipercorrección en visión lejana en 5 casos que se resolvió a los 3 meses después de la operación. No hubo hipercorrección en visión de cerca excepto en un caso. Ninguno de los casos operados presentó hipercorrección al final del seguimiento. La desviación horizontal final fue ≤8dp en visión cercana, excepto en 3 casos (media: 6,22). Los síntomas y la diplopía se resolvieron en 8 casos. El seguimiento medio fue de 10,33 meses. Conclusión El mini-plegamiento central de 1 o 2 músculos rectos mediales puede mejorar los síntomas y signos de exotropía asociados a la insuficiencia de convergencia cuando los ejercicios y los prismas son rechazados por los pacientes o cuando estos abordajes no han resuelto el problema (AU)

Objective To study the outcomes of treatment with central mini-plication of the medial rectus (MR) muscles in adult convergence insufficiency with diplopia. Methods The study sample comprised 9 cases (7 women). The length of MR plication was collected. Other variables reported were postsurgical deviation, overcorrections in the early postoperative period and at the end of follow-up, final horizontal deviation at near and at distance vision, diplopia, and mean follow-up from surgery. Surgical outcome was considered to be favorable when diplopia and symptoms were resolved and final exotropia at near was ≤8 pd at the end of follow-up. Results A central mini-plication of the MR was performed in 9 patients (8 unilateral). Mean (± SD) age was 58.66 (21.39) years. Mean near preoperative deviation: 16.22 (± 2.9) pd and distance preoperative deviation: 6.88 (± 4) pd Overcorrection at distance vision was recorded in 5 cases; this resolved by 3 months postoperatively. There was not overcorrection at near vision except one case. None of the cases operated on had overcorrection at the end of follow-up The final horizontal deviation was ≤8 pd at near vision, except for 3 cases (mean: 6.22). Symptoms and diplopia resolved in 8 cases. The mean follow-up was 10.33 months. Conclusion Central mini-plication of 1 or 2 medial rectus muscles can improve the symptoms and signs of exotropia associated with convergence insufficiency when exercises and the prisms are rejected by the patients and when these approaches have not solved the problem (AU)

Purpose To evaluate the efficacy and safety of inferior oblique muscle transposition and myopexy in patients with mild/moderate inferior oblique muscle overaction, with or without diplopia. Method We retrospectively analysed data for the 12 patients who underwent the technique. Data were collected from October 2018 to September 2021. Surgery was performed by suturing the inferior oblique belly to the sclera at 5mm posterior to the temporal end of the inferior rectus. All 12 patients had mild hypertropia (≤6 prism diopters [pd]) in primary position and mild/moderate inferior oblique overaction. Mean preoperative hypertropia was 4.42pd ±1.62. Diplopia was recorded in 10 cases. The diagnoses were fourth nerve paresis (9), unilateral primary inferior oblique overaction (2) and dissociated vertical deviation (1). Torticollis was observed in 7 cases, 2 had subjective torsion and 2 objective torsion. Results Mean age was 46.86±25.1 years (50%: men). Diplopia resolved in 9 of the 10 cases. The mean final vertical deviation was 1.5±2.93 (P=.001) pd in straight gaze. Of 7 mild overshoot in adduction, it disappeared in 3 and 4 remained the same. Of 5 moderate overshoot in adduction, 2 improved to mild and 3 disappeared. Torticollis was eliminated in 5 patients and improved in another 2. Mean time from surgery was 14.08±8.05 months. There were no overcorrections Conclusions Inferior oblique muscle transposition with myopexy is a safe and effective procedure in patients with mild-to-moderate inferior oblique muscle overaction and small-angle hypertropia, with or without diplopia (AU)
