Muscle Union Procedure in Patients with Paralytic Strabismus
PLOS ONE, 2015Co-Authors: Kyung-ah Park, In-jeong Lyu, Jung-min Yoon, Un-chang Jeong, Han Woong LimAbstract:To present the surgical outcomes of a muscle union procedure in patients with Paralytic Strabismus, this retrospective study included 27 patients with Paralytic Strabismus who underwent a muscle union procedure. In this procedure, the two vertical rectus muscles are united with the Paralytic horizontal muscle without splitting the muscles. Postoperative ocular deviations, complications, surgical success rates, and reoperation rates were obtained by examining the medical records of the patients. Seventeen patients had a sixth cranial nerve palsy, seven patients had a third cranial nerve palsy, and three patients had a medial rectus muscle palsy after endoscopic sinus surgery. The mean preoperative angle of horizontal deviation in the primary position was 56 ± 21 prism diopters. The mean follow-up period was 12 ± 9 months. The mean final postoperative ocular deviation was 8 ± 13 prism diopters. The success rate was 74%, and the reoperation rate was 0%. No significant complications, including anterior ischemia, occurred in any of the patients. One patient exhibited an increase in intraocular pressure in the immediate postoperative period, but this resolved spontaneously within 1 week. Our muscle union procedure was effective in patients with Paralytic Strabismus, especially in patients with a large angle of deviation. This muscle union procedure is potentially a suitable option for muscle transposition in patients with Paralytic Strabismus who have large-angle deviation or a significant residual angle after conventional surgery.

Estrabismo paralítico: revisão de 24 anos da Santa Casa de São Paulo Paralytic Strabismus: review of 24 years at "Santa Casa de São Paulo"
Conselho Brasileiro de Oftalmologia, 2007Co-Authors: Gustavo Bueno De Camargo, Wilson Takashi Hida, Mauro Goldchmit, Carlos Fumiaki Uesugui, Carlos Ramos De Souza-diasAbstract:OBJETIVO: Avaliar a incidência, etiologia e evolução dos estrabismos paralíticos ou paréticos. MÉTODOS: Foram selecionados retrospectivamente 519 prontuários de pacientes com paresia ou paralisia isolada dos músculos inervados pelos III, IV ou VI nervos cranianos, a partir de 11.000 prontuários da Seção de Motilidade Extrínseca Ocular do Departamento de Oftalmologia da Santa Casa de São Paulo de janeiro de 1980 a outubro de 2004. Foram estudados: o nervo craniano acometido, o olho acometido, o sexo, os fatores etiológicos e a evolução desses pacientes. RESULTADOS: Dos 519 pacientes, 17,1% foram casos congênitos e 82,9% foram adquiridos. O nervo craniano mais afetado foi o VI (49,7%). Os pacientes do sexo masculino foram mais acometidos, com 58,1% dos casos. A etiologia traumática foi a mais freqüente nos casos de paresia ou paralisia de III (43,0%), IV (52,4%) e VI (48,8%) nervos cranianos. Os pacientes evoluíram mais freqüentemente para cirurgia nos três grupos: III nervo (42,9%), IV nervo (73,2%) e VI nervo (43,2%). CONCLUSÃO: O VI nervo craniano foi o mais freqüentemente acometido e o fator etiológico mais importante foi o traumatismo, dados esses que coincidem com os encontrados na literatura.PURPOSE: To describe the incidence, etiologies and follow-up of patients with Paralytic Strabismus. METHODS: Retrospective study of 519 strabismic patients with isolated III, IV or VI cranial nerve palsy of 11,000 charts of the Ocular Motility Section of the Department of Ophthalmology of "Faculdade de Ciências Médicas Santa Casa de São Paulo", Brazil, between January 1980 and October 2004. This study analyzed: the injured cranial nerve, affected eye, sex distribution, etiology and follow-up. RESULTS: It was found that 17.1% of the cases were congenital and 82.9% acquired. The VI cranial nerve was the most frequently affected (49.7%). The incidence was higher in males (58.1%). Traumatism was the most common cause of III (43.0%), IV (52.4%) and VI (48.8%) nerve palsy. Surgery was performed in the three groups: third nerve (42.9%), fourth nerve (73.2%) and sixth nerve (43.2%). CONCLUSIONS:The sixth cranial nerve was the most frequently affected and the most common cause was traumatism, the same as observed in the literature

two cases of Paralytic Strabismus treated with acupuncture and herbal medicine
The Journal of Korean Medicine Ophthalmology and Otolaryngology and Dermatology, 2003Co-Authors: Seungeun Lee, Yoonbum KimAbstract:Strabismus refers to a extra-ocular muscle imbalance that results in improper alignment of the visual axes of two eyes. It may be divided into Paralytic and non-Paralytic Strabismus. Paralytic Strabismus is primarily a neurological problem: non-Paralytic Strabismus is more strictly an ophthalmologic problem. This case report focuses on Paralytic Strabismus resulting from palsies of the third and the sixth cranial nerves, respectively. Oculomotor nerve palsies result in binocular diplopia with characteristic patterns of Strabismus. Oculomotor nerve provides motor and parasympathetic innervation to the eyes. Acquired oculomotor nerve palsies are not uncommon. Injury to the third nerve may result in complete or partial dysfunction. Complete third nerve palsy is manifested by ptosis, dilated pupil, an eye that is deviated down and out in primary position, and limited adduction, elevation, and depression. Patients with unilateral sixth nerve palsy complain of binocular, horizontal diplopia esotropia in the primary position due to unopposed action of the medial rectus and limitation of abduction due to weakness of the lateral rectus. Diplopia is worse in the direction of the paretic lateral rectus muscle. Paralytic Strabismus are treated, based on the theory of Oriental medicine. with berbal medicines having gun-bi(健脾), bae-to(培土), gue-pung(祛風) effect of acupuncture around the eyes and etc. We describe a 63-year-old woman with complete the 3rd cranial nerve palsy and a 32-year-old woman with the unilateral 6th cranial nerve palsy who treated with acupuncture and herbal medicines and showed complete recovery.

a casuistics of a patient with facial palsy and Paralytic Strabismus
The Journal of Korean Medicine Ophthalmology and Otolaryngology and Dermatology, 2000Co-Authors: Jaehun Cho, Yoonbum Kim, Byungyoon ChaeAbstract:1. We experienced one case with facial palsy and Paralytic Strabismus, which improved under the treatment of Acupuncture, Infrared, Electroacupuncture and Massage. 2. The prognostic factor of facial palsy was affected by On Set and neurodegeneration (such as synkinesis, contraction, spasm and crocodile tear). 3. In facial palsy, Myoneural Excitability Test by Electroacupuncture, which will need the objective clinical standard, was available for the evaluation of therapeutic effect and prognosis.

a case of Paralytic Strabismus of abducens nerve by acupuncture and herbal medicines
The Journal of Korean Medicine Ophthalmology and Otolaryngology and Dermatology, 1994Co-Authors: Joongho Kim, Yoonbum Kim, Byungyoon ChaeAbstract:We report one case with paralysis of the sixth cranial nerve, which was diagnosed at Kyung Hee Unversity Hospital. The patient was happened with traffic accident. He showed disorder of both abduction eye movement, headache, double vision and dizziness. We have experienced good improvement to recover Paralytic Strabismus by the Oriental Medicine.
