ABSTRACT
El propósito es identificar a través de una revisión sistemática de la literatura, la evidencia actual frente a la eficacia del tratamiento de la insulina tópica en patologías de la superficie ocular. Se implementó una búsqueda de literatura en bases de datos de indexación médica Medline (Pubmed), Embase y Web Of Science a través de palabras claves como «insulin» AND «córnea» OR «corneal» OR «dry eye» artículos publicados en inglés o español en los últimos once años (2011-2022). Se identificaron nueve artículos con 180 participantes provenientes de Estados Unidos, España, Irlanda, Canadá, Portugal y Malasia, con defectos epiteliales persistentes refractarios y secundarios a vitrectomía, cuya extensión de la lesión fue de 3,75 mm2 hasta 65,47 mm2. La preparación fue disuelta con lágrimas artificiales y la concentración de insulina fue desde 1 UI/ml hasta 100 UI/ml. En todos los casos la resolución del cuadro clínico fue completa con un tiempo de curación desde 2,5 días hasta 60,9 días siendo este último un caso secundario a una quemadura por cáusticos de difícil control. La insulina tópica ha sido efectiva para el tratamiento de defectos epiteliales persistentes; la de acción intermedia y en bajas concentraciones demostró menor tiempo de resolución, en úlceras neurotróficas y secundarias a vitrectomías (AU)
The purpose is to identify, through a systematic literature review, the current evidence regarding the effectiveness of topical insulin treatment in ocular surface pathologies. A literature search was implemented in Medline (Pubmed), Embase and Web Of Science medical indexing databases by using keywords such as insulin AND cornea OR corneal OR dry eye in published papers in English or Spanish within the last eleven years (2011-2022). Nine papers were identified with 180 participants from the United States, Spain, Ireland, Canada, Portugal and Malaysia, with persistent refractory epithelial defects and secondary to vitrectomy, whose extension of the lesion was from 3.75 mm2 to 65.47 mm2. The preparation was dissolved with artificial tears and the insulin concentration ranged from 1 IU/ml to 100 IU/ml. In all cases, the resolution of the clinical picture was complete with a healing time from 2.5 days to 60.9 days, the latter being a secondary case to a difficult-to-control caustic burn. Topical insulin has been effective for the treatment of persistent epithelial defects. The intermediate action and low concentrations showed a shorter resolution time in neurotrophic ulcers and induced during vitreoretinal surgery (AU)
