“…BagIn our clinical practice, we were often in doubt about our results. Because in myopic patients some muscles such olini et al [7] suggested that pressure of the large globe on the lateral rectus muscle resulted in paralysis of the as the lateral rectus can be reduced in size, in accordance with different authors' results, pathologic values can be muscle with esotropia in 6 patients. They proposed that in addition to the paralysis of the lateral rectus muscle, considered normal by mistake.…”

The aim of this study was to establish the range of diameters of extraocular muscles in myopic patients and to obtain the baseline data to follow progression or regression of pathologies involving them. Standardized A scan and B scan ultrasound was used to measure the thickness of straight extraocular muscles at the muscle belly. No statistical differences were seen between right and left eyes. We found no consistent correlation with age or with axial length in the control or in the myopic patients (p>0.05). Diameters in myopic and control eyes were similar. This lack of difference between myopic and control muscle sizes means that we can obtain accurate measurements also from myopic patients.

“…They range from an inflammatory disease, which causes an atrophy of the lateral recti muscles, to a mechancal lesion of these muscles due to a contact of the enlarged and deformed eyeball with the orbital wall. [6][7][8][9][10][11][12] Currently, the most accepted theory, first proposed by Krzizok,13 suggests that a progressive prolapse of the posterior portion of the eyeball to the superotemporal quadrant of the orbit, outside of the tissues with support function (pulley) and the muscular cone, occurs in patients with high myopia. The prolapsed portion of the bulb causes a nasal displacement of lateral rectus (LR) muscle toward the bottom and superior rectus (SR) muscle nasally.…”

Purpose To describe the results achieved using muscle belly union associated with the recession of the ipsilateral medial rectus muscle to treat myopic myopathy and restore the normal anatomical relationship of superior and lateral rectus (LR). Methods A retrospective, nonrandomized study performed on 33 eyes of 26 patients who underwent muscle belly union between January 2004 and October 2012. We preoperatively and postoperatively recorded: best-corrected visual acuity; refraction; intraocular pressure; complete orthoptic assessment, including the angle of deviation and maximal abduction measured using the Goldmann perimeter. Pictures of the eyes in all gaze directions were taken before and after the surgical treatment. Anatomical relationships between muscle cone and eye globe were preoperatively analyzed using magnetic resonance imaging (MRI). Surgical complications were noted. Results The follow-up period was 6 months. Preoperative mean BVCA was 0.97 ± 0.96 logMAR (ranging from 0.1 to 3 logMAR) and no changes were detected during postoperative controls. Preoperative mean hypotropia and esotropia were, respectively, 10.2±3.9 prism diopters (PD) and 46.2±15.5 PD. Postoperative mean hypotropia was 2.48±2.00 PD (Po0.001) and mean esotropia was 7.36 ± 9.09 PD (Po0.001). A statistical incrementation of mean maximal abduction (Po0.001) was also noticed. Conclusions Muscle belly union-coupled with the recession of the ipsilateral medial rectus muscle when considered convenientis the elective surgical technique in myopic myopathy, when a downward displacement of LR muscle is shown on MRI with coronal sections.

“…Bagolini et al (12) , estudando 6 pacientes com "síndrome da esotropia miópica adquirida progressiva", notaram que todos os olhos tinham comprimeto axial aumentado e alta miopia. Os pacientes foram submetidos a TC e ecografia, através do que mediram os espaços entre a parede orbitária lateral e o bulbo.…”

“…Estudos histológicos do reto lateral de pacientes esotró-picos míopes revelaram, através de microscopia eletrônica, presença de fibrose e aumento do tecido conectivo intersticial, com espessamento da membrana basal do endotélio capilar (7,(12)(13) . A redução da função muscular, associada à miopia progressiva, demonstrada nesses trabalhos, sugere a hipótese de tratar-se de paresia miogênica.…”

Objetivo: Análise dos resultados cirúrgicos da correção dos estrabismos horizontais em portadores de alta miopia, em pacientes do Departamento de Oftalmologia da Santa Casa de Misericórdia de São Paulo. Métodos: Foram estudados os prontuários de 24 pacientes esotrópicos e 17 exotrópicos, portadores de miopia maior que 6,00 DE operados para correção do estrabismo. Consideramos como bons resultados cirúrgicos desvios residuais entre esotropia e exotropia de 10∆. Resultados: Observou-se grande incidência de maus resultados entre os pacientes esotrópicos altos míopes. Conclusão: Concluímos que existe uma tendência a piores resultados cirúrgicos nos pacientes esotrópicos com miopia maior que -6,00 DE, em comparação com esotrópicos com erro refrativo entre -0,75 DE e +3,50 DE.
