“…We agree with other authors who recommend waiting over six months before prescribing surgery in order to allow time for the deviation to stabilise or resolve (14,15). The six patients who had an evolution of diplopia under six months were offered treatment with botox; only four accepted.…”

“…Some authors published good results only with prismatic treatment, but don't have any case of restrictive strabismus and the deviations are small (10). In general, a large percentage of cases (which is variable indifference publications) will require surgery (1,2,5,6,8,(13)(14)(15). In this small sample we have operated four of the eight patients with a retrocession of the inferior rectum in three and a retrocession of the medial rectum in one.…”

“…The mean time since the appearance of diplopia up to our first treatment was of 5 months, SD: 5.45 (range [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Table II shows data referring to the treatments and their results.…”

Purpose: To study the clinical signs, treatment and prognosis of strabismus after sub-Tenon's anesthesia for cataract surgery. Methods: Eight patients without previous strabismus developed incommitant diplopia immediately after cataract surgery; the left eye was affected in five patients and the right eye in three. Restrictive strabismus was diagnosed with the cover test, prisms, and active and passive ductions in all cases. In seven cases the deviation was vertical and in one patient it was horizontal. The average deviation was 17.5 S.D. 9.84 (range 5-35) prismatic dioptres in primary position. The deviation increased looking upward in seven cases, and looking sideways to the left in the other. It was considered to be a good result if the diplopia disappeared after treatment. Results: Botulinum toxin was the first treatment applied in four patients, but only one showed a good response and required no further therapy. Strabismus surgery was required in four cases, and prisms were adapted in three. Three patients required two strabismus operations. A good result was achieved in all cases, with the average time interval being 10.12 (SD 5.5) months. ORIGINAL ARTICLE RESUMENObjetivo: Estudiar las características del estrabismo secundario a la cirugía de catarata con anestesia subtenoniana; su tratamiento y pronóstico. Método: Ocho enfermos sin estrabismo previo presentaron diplopía inmediatamente después de la cirugía de catarata; cinco de ojo izquierdo, tres de ojo derecho. La exploración con cover test, prismas y ducción activa y pasiva mostró estrabismo restrictivo: siete de componente vertical y uno horizontal. La desviación media fue de 17,5 DE: 9,84 dioptrías prismáticas (rango 5-35) en la mirada al frente. La posición máxima de desviación fue en supraversión en siete, y en levoversión en otro. Todos tenían diplopía invalidante. Se considera buen resultado si desaparecía la diplopía con el tratamiento. Resultados: Cuatro casos recibieron tratamiento quirúrgico, en uno sólo se inyectó toxina botulínica y en tres se pusieron prismas. La toxina botulínica se empleó como primera opción en cuatro casos y sólo fue eficaz en un enfermo. De los cuatro casos operados, tres necesitaron dos cirugías y un paciente sólo un tiempo quirúrgico. Se consiguió buen resultado en los ocho pacientes tratados. El tiempo medio de evolución fue de 10,12 DE: 5,46 meses. 142ARCH SOC ESP OFTALMOL 2006; 81: 141-146 MERINO P, et al.

“…This last category has received much attention recently as a potentially avoidable cause of vertical diplopia. Strabismus of this type has been attributed to bridle‐suture trauma to the superior or inferior rectus muscle, direct needle trauma to muscles or related nerves from the retrobulbar needle, ischaemic injury of the muscle from swelling and haematoma formation and an inflammatory reaction to subconjunctival gentamicin; however, most authors now believe that squint is mediated by the myotoxic effect of the local anaesthetic during the retrobulbar injection . The capacity of commonly used local anaesthetics to permanently damage extraocular muscles is now well established.…”

Diplopia is an infrequent but distressing adverse outcome after uncomplicated cataract surgery. Many factors may contribute to the occurrence of this problem, including prolonged sensory deprivation resulting in disruption of sensory fusion, paresis of one or more extraocular muscles, myotoxic effects of local anaesthesia, optical aberrations (for example, aniseikonia) and pre-existing disorders (for example, thyroid orbitopathy). The purpose of this review is to present the aetiology and clinical features of diplopia after cataract surgery and to discuss the possible modalities for the prevention and treatment of this frustrating complication.

“…163 Subsequently, many cases of vertical diplopia due to inferior rectus muscle restriction following cataract surgery with retrobulbar anaesthesia were reported. [166][167][168] In addition, superior rectus muscle overaction can result from transient postoperative weakness of the inferior rectus muscle, and presents as hypertropia which is worse in upgaze. 169 In these patients, a temporary paralysis or weakening of an extraocular muscle led to a contracture or strengthening of the antagonist muscle.…”
