Intravascular papillary endothelial hyperplasia (Masson's tumor) of the conjunctiva. Unusual location of a rare vascular tumor.

Intravascular papillary endothelial hyperplasia (IPEH) is characterized by proliferation of endothelial cells usually occurring within a long-standing vascular malformation or tumor. IPEH usually affects neck, head and lower extremities, and few orbital and eyelid cases have been reported. We present a unique case, a 48-years-old man with a purple, elevated, multilobular conjunctival lesion of three-weeks duration that underwent an excisional biopsy. Pathological features revealed intravascular papillary endothelial hyperplasia (Masson's tumor).

Femto-LASIK outcomes obtained by a fellowship trainee during a refractive surgery training program.

PURPOSE: To report, for the first time, the clinical outcomes and patient satisfaction of laser refractive surgery performed by a trainee during a corneal and refractive surgery fellowship program in Latin America. METHODS: This prospective and interventionist study reviewed the clinical charts of the first 100 consecutive refractive surgery cases performed by a single Cornea Fellowship trainee between March 2018 and June 2018 in the Blindness Prevention Association of Mexico (Asociación para Evitar la Ceguera en Mexico). Femtosecond LASIK was performed in all eyes. Visual and refractive outcomes were evaluated during the first year of follow-up. Patient satisfaction was measured using 5 author-created questions 6 months after surgery. RESULTS: Data of 100 eyes of 50 consecutive patients were evaluated. One year after the surgery, mean uncorrected distance visual acuity (UDVA) was 0.01 logMAR. Spherical equivalent error passed from -3.91 ± 2.28 D preoperatively to -0.22 ± 0.28 D. No eyes lost lines in corrected distance visual acuity (CDVA). Manifest refraction maintained stable during the first year after surgery. The five author-created questions revealed a high level of confidence and patient satisfaction. CONCLUSIONS: Femto-LASIK performed by a corneal and refractive surgery fellowship trainee showed good refractive and visual outcomes, as well as high patient satisfaction and confidence in a refractive surgery centre in Latin America.

Resultados de Femto-LASIK obtenidos por un fellow durante un programa de formación en cirugía refractiva / Femto-LASIK outcomes obtained by a fellowship trainee during a refractive surgery training program

Objetivo Informar por primera vez sobre los resultados clínicos y la satisfacción de los pacientes operados de cirugía refractiva con láser por un fellow durante un programa de formación en cirugía corneal y refractiva en Latinoamérica. Métodos En este estudio prospectivo e intervencionista se revisaron las historias clínicas de los primeros 100 casos consecutivos de cirugía refractiva realizados por un solo fellow del departamento de córnea de la Asociación para Evitar la Ceguera en México entre marzo de 2018 y junio de 2018. La técnica LASIK asistida por femtosegundo se realizó en todos los ojos. Los resultados visuales y refractivos se evaluaron durante el primer año de seguimiento. La satisfacción del paciente se midió 6 meses después de la cirugía con 5 preguntas creadas por el autor. Resultados Se evaluaron datos de 100 ojos de 50 pacientes consecutivos. Después de 12 meses de la cirugía, la agudeza visual no corregida (AVNC) fue de 0,01logMAR. El equivalente esférico pasó de –3,91±2,28D preoperatoriamente a –0,22±0,28D. No se perdieron líneas en la agudeza visual mejor corregida (AVMC). La refracción manifiesta se mantuvo estable durante el primer año después de la cirugía. Las 5 preguntas creadas por el autor revelaron un alto grado de confianza y satisfacción del paciente. Conclusiones Los resultados refractivos y visuales obtenidos mediante Femto-LASIK por un fellow de cirugía corneal y refractiva fueron buenos. Del mismo modo se demostró una alta satisfacción y confianza del paciente en el cirujano en periodo de aprendizaje en un centro formativo de cirugía refractiva en Latinoamérica (AU)

Miopexia retroecuatorial del músculo oblicuo inferior: un debilitamiento alternativo / Inferior oblique retro-equatorial myopexy: An alternative weakening

OBJETIVO: Describir una alternativa quirúrgica para tratar la hiperacción del oblicuo inferior y presentar los primeros resultados con dicha técnica. MATERIAL Y MÉTODOS: Un total de 6ojos consecutivos de 6 pacientes con hiperacción primaria o secundaria del oblicuo inferior se sometieron a una operación de miopexia retroecuatorial del oblicuo inferior bajo anestesia general. Los resultados primarios medidos fueron la desviación vertical postoperatoria en el campo de acción del músculo oblicuo inferior y las complicaciones quirúrgicas intraoperatorias y postoperatorias. Los resultados finales se evaluaron después de 6 meses de cirugía. RESULTADOS: La muestra de pacientes consistió en 3 niñas y 3 niños de entre 3 y 7 años. La media de la hiperacción del oblicuo inferior preoperatoria fue 34 ± 4,6°, equivalente a 3+. La hiperacción del oblicuo inferior se redujo en todos los pacientes, siendo la media de reducción de 28 ± 1,98° y la desviación postoperatoria media de 6 ± 2,84°. Cuatro de 6ojos obtuvieron un éxito total, y solo un caso quedó sin corregir. No se produjeron complicaciones intraoperatorias o postoperatorias. CONCLUSIÓN: La miopexia retroecuatorial del músculo oblicuo inferior es un enfoque quirúrgico alternativo para la hiperacción del oblicuo inferior. Es una técnica eficiente, segura y reversible que podría usarse en casos de hiperacción del oblicuo inferior entre 2+ y 3+

PURPOSE: To describe an alternative surgical approach to treat inferior oblique overaction and report the first results of this technique. MATERIALS AND METHODS: A total of 6 consecutive eyes of 6patients with primary or secondary inferior oblique overaction underwent inferior oblique retro-equatorial myopexy under general anaesthesia. The primary outcomes measured were the postoperative vertical deviation in the field of action of the inferior oblique muscle, and the intra- and postoperative surgical complications. Final results were evaluated at six-months after surgery. RESULTS: The patient population consisted of 3 girls and 3 boys aged between 4 and 7 years old. The mean preoperative inferior oblique overaction was 34° ± 4.6°, equivalent to 3+. Inferior oblique overaction was reduced in all patients with a mean reduction of 28° ± 1.98°, and the mean postoperative deviation was 6° ± 2.84°. Total success was achieved in four out of six eyes, and only one case remained under-corrected. No intra- or postoperative complications were reported. CONCLUSION: Inferior oblique retro-equatorial myopexy is an alternative surgical approach for inferior oblique overaction. It is an efficient, safe, and reversible technique that could be used in cases of inferior oblique overaction between 2+ to 3+

Queratoplastia lamelar anterior en el manejo de un tumor dermoide central en un bebé / Anterior lamellar keratoplasty for the management of a central dermoid tumour in a baby

Bebé de 3 meses de edad al que traen por presencia desde el nacimiento de una lesión blanquecina sobre la córnea del ojo derecho. Debido a las características clínicas y ultrasónicas de la lesión, se realizó una queratoplastia lamelar anterior manual. La anatomía patológica demostró la presencia de un coristoma epibulbar simple de grado II. Los tumores dermoides suelen ser considerados benignos, pero pueden afectar de manera muy grave a la visión de un paciente pediátrico en función de su localización. La posibilidad de ambliopía en este tipo de casos obliga a procedimientos quirúrgicos con relativa urgencia. En los casos de afectación del eje visual sin implicaciones intraoculares la técnica de elección es la queratoplastia lamelar anterior

A 3-month-old baby presented with a whitish lesion over the right cornea since birth. Due to the clinical and ultrasonic characteristics of the lesion, a manual anterior lamellar keratoplasty was performed. Histopathological examination showed it to be a simple grade II epibulbar choristoma. Although dermoid tumours are usually considered as benign, some of them, depending on their location, can seriously affect the vision of a paediatric patient. Due to the high probability of amblyopia in these cases, a surgical procedure is mandatory. Anterior lamellar keratoplasty is recommended when the visual axis is compromised without intraocular implications

Nevus compuesto inflamatorio juvenil: no es melanoma todo lo que parece / Inflammatory juvenile compound nevi: A melanoma is not all that it appears to be

Niña de 11 años que acude por crecimiento rápido de lesión pigmentada en conjuntiva bulbar del ojo izquierdo. Debido a las características biomicroscópicas y ultrasónicas de la lesión se realizó una biopsia escisional con técnica "no touch" y criocoagulación en márgenes quirúrgicos. La anatomía patológica demostró la presencia de un nevus compuesto inflamatorio de conjuntiva. Los tumores melánicos de la conjuntiva son en su gran mayoría benignos. Sin embargo, el crecimiento acelerado de una lesión, la vascularización de la misma, los márgenes irregulares y la diferente coloración deben hacer pensar en una malignización. En tal caso, la biopsia escisional es obligatoria. A pesar de todas las características clínicas de malignidad, principalmente en jóvenes, puede tratarse de un nevus compuesto inflamatorio

An 11 year-old girl presented with a recent growth pigmented conjuntival lesion in the bulbar conjunctiva of left eye. Due to the the biomicroscopic and ultrasound findings, an excisional biopsy was performed on the lesion using the "no touch" technique, as well as cryo-coagulation of surgical margins. Histopathological examination revealed an inflammatory compound nevus. Melanotic conjunctival tumours are mostly benign. However, the recent growth of a lesion, its vascularisation, irregularities of the margins, and colour change must suggest it has turned malignant. In such case, excision of the lesion is mandatory. Despite all the clinical changes, especially in young patients, it can still be an inflammatory compound nevus

Queratolisis tras cirugía de catarata en paciente con enfermedad autoinmune / Corneal melting after cataract surgery in a patient with autoimmune disease

Caso clínico: Mujer de 78 años con artritis reumatoide y síndrome de Sjögren secundario presentó una lisis estromal corneal 3 días después de la extracción de cataratas requiriendo queratoplastia penetrante. Al cuarto mes, necesitó un segundo trasplante de córnea debido a un nuevo descematocele asociado a su enfermedad sistémica. Discusión:La enfermedad de base junto con el antecedente quirúrgico fueron responsables del cuadro que presentamos. La correcta anamnesis previa a la cirugía de cataratas, el tratamiento preoperatorio de la enfermedad de base de la superficie ocular, una técnica depurada y un estrecho control postoperatorio pueden evitar una complicación tan grave. Los tratamientos inmunomoduladores son fundamentales en este tipo de pacientes (AU)

Case report: A 78-year-old woman with rheumatoid arthritis and secondary Sjögren's syndrome presented with corneal melting three days after cataract extraction that required penetrating keratoplasty. By the fourth month, a second corneal transplant was needed due to a new descemetocele associated with her systemic disease. Discussion: The underlying disease, together with the surgical history, was responsible for the complication presented. The correct anamnesis prior to cataract surgery, a refined technique, and a close post-operative follow-up can avoid such a serious complication. Immunomodulatory treatments are essential in this type of patient (AU)
