“…3,6,12 Scott et al 22 have recently shown that direct local anaesthetic injection into the muscle can lead to initial myotoxicity, which is followed by hypertrophy of the muscle and this is consistent with our findings. Also discussing this, Capo and Guyton 6 postulated that the involved muscle can overact as a result of posterior segmental myotoxicity, which is not extensive enough to produce classical restrictive strabismus with positive forced duction testing.…”

“…However, the substantial benefit of visual acuity improvement resulting from cataract extraction can be reduced by the introduction of post-operative diplopia. Most of the recent literature regarding the cause of this complication [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] has focused on anaesthetic myotoxicity, trauma during infiltrational anaesthesia, or the use of a rectus bridle suture.…”

“…Among the affected extraocular muscles published in literature, the inferior rectus is involved more frequently due to its position vis-a-vis the needle of the retro-bulbar or peribulbar anesthesia (2,(4)(5)(6). The majority of research published in literature refers to a higher prevalence of vertical strabismus and (among these) hypotropies instead of hypertropies (2,(6)(7)(8). Retro-bulbar and peri-bulbar anesthesia are the types of anesthesia that cause the problem (7).…”

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.

In recent years anesthesia modalities have changed in ophthalmic surgery. A growing trend toward the use of topical anesthesia in cataract surgery is apparent. The present-day techniques used in ophthalmic surgery are retrobulbar anesthesia, peribulbar anesthesia, subtenon anesthesia, and subconjunctival anesthesia as injection techniques, topical anesthesia using drops, gel, or sponge, and intracameral anesthesia. Injectable anesthesia (RBA, PBA, STA) provides a higher level of analgesia and globe akinesia. With injection techniques the risks of vis a tergo and anesthetic complications increase; the level of analgesia after topical anesthesia could be improved by supplementation with i.v. narcotics.
