Application of rectus muscle transplantation optimization for refractory single eye insufficiency / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To investigate the application of rectusmuscle transplantation optimization in the treatment of refractory supraventricular insufficiency in one eye caused by double supraventricular paralysis with inferior rectus restriction and high original vertical strabismus. <p>METHODS: Retrospective analysis was performed on 6 cases of double superior muscle palsy admitted to our hospital from January 2015 to January 2019. After the failure of conservative treatment, rectus muscle transplantation optimization was adopted to observe the improvement of preoperative and postoperative eye position, vertical strabismus, motor function of upper and lower rotation of paralytic eye, as well as the improvement of pseudo ptosis and compensated head position. <p>RESULTS: After the restriction was lifted, rectusmuscle transplantation optimization was performed. The original <i>in situ</i> vertical strabismus degree before surgery, one month and six months after surgery were(49.83 ± 6.55)PD,(2.67±2.07)PD, and(1.83±2.40)PD. There was a significant difference in vertical strabismus before and after 1mo and 6mo of operation(<i>P</i><0.001). There was no significant difference in the comparison of vertical strabismus between 1mo and 6mo of operation(<i>P</i>=0.899). All patients had the orthotopic position in postoperative position, and the paralysis function of the paralyzed eyes improved significantly after the operation; Pseudopterygoptosis in four cases and compensatory head position in two cases before operation were significantly improved after operation. <p>CONCLUSION: Optimization of rectus muscle transplantation is suitable for unilateral superior rotation deficiency with limitation of inferior rectus, which can effectively improve the superior rotation function of affected eye with stable curative effect.

Deficiencia monocular de la elevación con esotropía / Monocular elevation deficiency with esotropia

RESUMEN La deficiencia monocular de la elevación se define como la limitación de la elevación del ojo afectado desde cualquier posición de la mirada, con ducciones normales en todas las demás posiciones. La pseudoptosis se puede presentar en posición primaria de la mirada; sin embargo, el 25 por ciento de los casos puede mostrar una ptosis verdadera. Se presenta un paciente masculino de 11 años de edad con antecedentes de estrabismo hacia adentro desde que nació, quien llevó tratamiento con oclusiones y cristales desde el primer año de edad. Al examen oftalmológico presentaba una agudeza visual mejor corregida de 1,0/0,4; a 6 metros en el ojo derecho 30 ∆ b externa ~18 ∆ b superior y en el ojo izquierdo 30 ∆ b externa ~18 ∆ b inferior; a 33 centímetros en el ojo derecho 30 ∆ b externa ~25 ∆ b superior y en el ojo izquierdo 30 ∆ b externa ~25 ∆ b inferior y limitación de la elevación en todas las posiciones horizontales de la mirada en el ojo derecho. Se realizó la prueba de ducción forzada y se encontró una restricción del recto inferior derecho, por lo que se decidió retroinsertar este músculo y ambos rectos medios. Se indicó la corrección óptica y la rehabilitación con oclusiones que mejoró la visión a 1,0/0,7. La cirugía correctiva logró la ortotropía y la mejoría de la agudeza visual(AU)

ABSTRACT Monocular elevation deficiency is defined as a limitation in the elevation of the affected eye from any position of gaze with normal ductions in all other positions. Pseudoptosis may occur in the primary position of gaze, but 25 percent of the cases are true ptosis. A case is presented of a male 11-year-old patient with a history of inward strabismus since birth, treated with occlusions and lenses as of his first year of life. At ophthalmological examination, best corrected visual acuity was 1.0/0.4; at 6 meters in the right eye 30 ∆ b outer ~18 ∆ b upper, and in the left eye 30 ∆ b outer ~18 ∆ b lower; at 33 centimeters in the right eye 30 ∆ b outer ~25 ∆ b upper, and in the left eye 30 ∆ b outer ~25 ∆ b lower, and elevation limitation in all horizontal gaze positions of the right eye. The forced duction test revealed a restriction in the lower right rectus muscle. It was thus decided to insert back the right rectus muscle and both medial rectus muscles. Optical correction and rehabilitation with occlusions improved the patient's vision to 1.0/0.7. Corrective surgery achieved orthotropy and improved visual acuity(AU)

Cavidades anoftálmicas atípicas / Atypical anophthalmic cavities

OBJETIVO: Determinar el comportamiento de las cavidades anoftálmicas atípicas en nuestro centro en cuanto a edad, sexo, causas de pérdida del globo ocular, técnica quirúrgica y sus principales alteraciones. MÉTODOS: Se realizó un estudio descriptivo de tipo prospectivo de 239 pacientes con diagnóstico confirmado de cavidades anoftálmicas atípicas que acudieron a la consulta de prótesis del ICO Ramón Pando Ferrer en el período de junio a diciembre del 2007. RESULTADOS: El 3 por ciento fueron menores de 20 años, el 30 por ciento entre los 21 y los 40 años, el 43 por ciento entre los 41 y 60 años y el 24 por ciento mayores de 60 años. El 74 por ciento fueron del sexo masculino. La pérdida del globo ocular por traumatismo fue en 115 pacientes para un 48,1 por ciento seguido de infecciones y glaucoma. El 69,5 por ciento fueron eviscerados y el 30,5 por ciento enucleados. El 64 por ciento tuvo patología conjuntival de ellos el 28 por ciento por retracción del férnix inferior. La pseudoptosis se presentó en el 49 por ciento. CONCLUSIONES: Las cavidades anoftálmicas atípicas resultaron más frecuentes entre los 41 y 60 años. Predominó el sexo masculino. Las principales causas de pérdida del globo ocular fueron el traumatismo seguido de infecciones. Predominó la evisceración como técnica quirúrgica. La mayoría de las cavidades atípicas resultaron ser por pérdida de fondo de saco inferior y malposiciones palpebrales

OBJECTIVE: To determine the situation of atypical anophthalmic cavities in our center in terms of age, sex, causes of eyeball loss, surgical technique and main alteration of the technique. METHODS: A prospective descriptive study was conducted in 239 patients with confirmed diagnosis in the period of June to December 2007. RESULTS: In this group of patients, 3 percent were under 20 years of age, 30 percent aged 21 to 40 y, 43 percent was in 41-60 y group and 24 percent were over 60 years. Males accounted for 74 percent. The eyeball loss due to trauma affected 115 patients for 48,1 percent followed by infections and glaucoma. In these patients, 69,5 percent were eviscerated and 30,5 percent were enucleated. Conjunctival pathology was present in 64 percent of them whereas lower fornix retraction affected 28 percent. Pseudoptosis was observed in 49 percent. CONCLUSIONS: Atypical anophthalmic cavities were more common in the 41-60y age group. Males prevailed. The main causes of the eyeball loss were trauma and infections. Evisceration was the most used surgical technique. Most of these atypical cavities were due to loss of the lower sac fundus and to palpebral malpositions

2-loop En Block Double Fold Operation through 3 Small Incision

Korean small eyes are characterized in thickness and pseudoptosis of the skin of the upper eyelid. They also have a large amount of subcutaneous and preaponeurotic fat. The hypertrophic orbicularis oculi muscles and the lower positioned transverse ligaments are included in their structural characteristics. These special features act as various burden factors in Korean double eyelid operation. Just burden factors restrict the movement of the upper eyelid and so Korean eyes looks like Ptosis (pseudoptosis). For creation of double fold eyelid, we performed continuous 2-loop single stitch buried suture to make an en bloc fixation with dermis, levator aponeurosis and Muller muscle through three small incisions. And then we tried to eliminate the burden factors through small sized lateral incision. After removal of the external sutures at postoperative 3 days, we obtained our intended double fold lines such as in-fold, in-ward fold and out fold successfully and only experienced minor complications such as edema, ecchymosis and loss of fold. And also the range of excursion in the upper eyelid improved without levator shortening or any other operation such as a sling. The objective of this article is to share our experience and to introduce our method of treating Korean pseudoptotic eyes by using 2-loop en bloc fixation through three small incisions with various reviews of literature.

A New Interpretation of Ptosis-like Eyes through the Results of Small-Incision Double-Eyelid Operation

PURPOSE: Perceiving the experience that MRD1 is increased after small-incision double-eyelid operation, it has been statistically verified the improvement of MRD1 retrospectively. Therefore, we suggest new interpretation for Korean-specific small eye and more definite classification for ptosis. METHODS: In operation, we made 3 small incisions according to the line designed on upper eyelid and removed some soft tissues including connective tissues. Then, figure-of-8 continuous buried ligation was performed through the incision windows. This study is a retrospective study, measures MRD1 changes and excursion distance change of eyelid margine and eyebrow using pre- and post-operative photos of 14 patients. RESULTS: Postoperative photos were taken on the 4th day and all of 14 patients had an improvement in MRD1 statistically. The excursion distance of upper eyelid was improved in half of patients, though not in the range of statistical verification. It was statistically confirmed that the movement of eyebrow was reduced after operation. CONCLUSION: It is thought that MRD1 improvement without any operation on levator complex means that soft tissue including connective tissue eliminated in operation restricts the movement of upper eyelid. It is defined such factors as burden factors and such phenomenon as burdened eyelid. It is thougt that Korean's small eye is mainly burdened eyelid and cosmetic improvement may be obtaind even by removing such burden factors.
