Oftalmomiasis orbitaria por Dermatobia hominis en un paciente inmunosuprimido en un área andina ecuatoriana / Orbital ophthalmomiasis due to Dermatobia hominis in an immunosuppressed patient from the ecuadorian andean area

Varón ecuatoriano de 83 años, indigente, con antecedente de desnutrición y alcoholismo crónico, acude por un cuadro clínico caracterizado por crecimiento progresivo de larvas a nivel ocular izquierdo (OI), asociado a áreas de putrefacción de tejidos oculares. Al ingreso, su visión en ojo derecho (OD) fue de movimiento de manos y el OI indicaba no percepción de luz, el segmento anterior de OD evidenció una catarata brunescente, sin otra alteración, mientras que el OI presentó edema, eritema bipalpebral y abundante cantidad de larvas móviles distribuidas en toda la órbita, asociado a áreas de necrosis, putrefacción y distorsión de la anatomía de los tejidos oculares. La tomografía de órbita mostró un compromiso importante de la órbita, indicándose manejo quirúrgico mediante exenteración orbitaria izquierda con identificación taxonómica de las larvas como Dermatobia hominis, asociado a ello, se implementó tratamiento antibiótico y realización de un colgajo fasciocutáneo frontal por el Departamento de Cirugía Plástica (AU)

An 83-year-old Ecuadorian male, indigent with a history of malnutrition and chronic alcoholism, presented with a clinical feature characterized by progressive growth of larvae at the left eye level (LE), associated with areas of ocular tissue putrefaction. Upon admission, his vision in the right eye (RE) was of hand movement and no light perception in LE, the anterior segment of the RE showed a brunescent cataract, with no other alteration, while the LE presented edema, bipalpebral erythema and an abundant number of mobile larvae distributed throughout the orbit, associated with areas of necrosis, putrefaction and distortion of the anatomy of the ocular tissues. Orbital tomography showed a significant compromise of the orbit, indicating surgical management by left orbital exenteration with taxonomic identification of the larvae as Dermatobia Hominis associated with it, antibiotic treatment was implemented and a frontal fasciocutaneous flap was performed by the plastic surgery department (AU)
