ABSTRACT
Introducción: Los mucoceles de senos paranasales pueden afectar la órbita, más frecuentemente cuando su localización es frontoethmoidal originando un efecto de masa. Objetivo: Reportar el compromiso orbitario y riesgo para la visión permanente en un caso de mucocele. Diseño del estudio: Reporte de caso Resumen del caso: Paciente femenina con proptosis unilateral progresiva de larga data, disminución progresiva de la agudeza visual y oft almoplegía. La tomografía computarizada de la órbita reveló un mucocele del seno etmoidal comprimiendo el nervio óptico y el ápex de la órbita. Posterior al manejo quirúrgico, etmoidectomia y drenaje del mucocele, se presenta una marcada mejoría de la función del nervio óptico, motilidad ocular y proptosis. Conclusión: Es muy raro que los mucoceles etmoidales afecten el nervio óptico sin embargo hay algunas características que los pueden llevar a afectar la visión: infección asociada, compromiso de las celdillas etmoidales posteriores o un mucocele gigante con tratamiento tardío. Es importante conocer los signos y síntomas oft almológicos que nos pueden ayudar a diagnosticar el compromiso orbitario por mucocele en etapas tempranas. Esta patología se debe atender de manera multidisciplinaria con especialistas en órbita y otorrinolaringología.
Background: Orbital involvement of sinus mucoceles, especially frontoethmoidal may result in orbital mass eff ect. Objective: Describe orbital involvement and potential for visual loss in a case with mucocele. Study design: Case report Case summary: Th ese is a patient with longstanding unilateral proptosis, progressive decrease in visual acuity and ophthalmoplegia. Orbital computed tomography (CT) revealed a large ethmoidal sinus mucocele compressing the optic nerve and orbital apex. Improvement in optic nerve function, motility and proptosis resulted from ethmoidectomy and mucocele drainage. Conclusion: Although frontoethmoidal mucoceles seldom aff ect the optic nerve, there may be cases with potential to aff ect vision; this may occur more frequently when a coexistent infection is present, when the posterior ethmoid cell is involved or when a giant mucocele is present and treatment is delayed. Th is pathology must be addressed in a multidisciplinary manner with otolaryngologists and orbit specialists.

Background: The management of Duane retraction syndrome (DRS) is challenging and may become more difficult if an associated accommodative component due to high hyperopia is present. The purpose of this study is to review clinical features and outcomes in patients with partially accommodative esotropia and DRS. Setting and Design: Retrospective, non‑comparative case series. Materials and Methods: Six cases of DRS with high hyperopia were reviewed. Results: Of the patients studied, the mean age of presentation was 1.3 years (range: 0.5‑2.5 years). The mean amount of hyperopia was + 5D (range: 3.50‑8.50) in both eyes. The mean follow up period was 7 years (range: 4 months‑12 years). Five cases were unilateral while one was bilateral. Four cases underwent vertical rectus muscle transposition (VRT) and one had medial rectus recession prior to presentation; all were given optical correction. Two (50%) of the four patients who underwent vertical rectus transposition cases developed consecutive exotropia, one of whom did not have spectacles prescribed pre‑operatively. All other cases (four) had minimal residual esotropia and face turn at the last follow‑up with spectacle correction. Conclusion: Patients with Duane syndrome can have an accommodative component to their esotropia, which is crucial to detect and correct prior to surgery to decrease the risk of long‑term over‑correction. Occasionally, torticollis in Duane syndrome can be satisfactorily corrected with spectacles alone.
