ABSTRACT
Purpose: To study facial nerve palsy (FNP) in post?COVID?19?mucormycosis patients and its ocular complications, report different presentations of FNP in such patients, and propose its etiopathogenesis based on presentation and clinico?radiologic localization. Methods: A prospective cohort study was carried out in patients of post?COVID?19?mucormycosis who presented at our tertiary center, over a period of 3 months. Motor and sensory examination of the facial nerve was done to diagnose FNP and localize the lesion clinically. Slit?lamp examination was done for grading corneal involvement. MRI brain, orbit, and paranasal sinuses (PNS) with contrast were studied to find involvement along the facial nerve. It was assessed whether this site of lesion corresponded with clinical localization. Data were analyzed using the percentage of total cases and Fisher抯 test. Results: A total of 300 patients with post?COVID?19 mucormycosis were examined, of which 30 (10%) patients were found to have FNP. All were lower motor neuron (LMN) type and were associated with corneal complications. The most common site clinically was distal to the chorda tympani (66.66%) and radiologically was infratemporal (IT) fossa (63.4%). The clinical localization significantly correlated with the radiological findings (P = 0.012). Twenty percent of patients showed incomplete involvement of facial muscles. Conclusion: FNP was found to be of LMN type. The most common site of insult was IT fossa. There was a good clinico?radiological correspondence of lesions. Isolated lesions were also found along the peripheral nerve course, presenting as incomplete facial palsy. Recognition of FNP in post?COVID?19 mucormycosis, in all its variable forms, is important to manage corneal complications
ABSTRACT
El empleo de lentes de contacto se ha incrementado a nivel mundial. En la actualidad su uso no se restringe solamente a la corrección óptica, sino que se utilizan con fines terapéuticos, ya que generan comodidad y estética en múltiples afecciones oculares. Es de esperar el creciente aumento de las complicaciones relacionadas con el uso de estos, por ser la queratitis bacteriana potencialmente grave y devastadora para el globo ocular. Se realizó una revisión bibliográfica acerca de las úlceras corneales en portadores de lentes de contacto con el objetivo de describir su epidemiología y las formas de prevenir esta complicación(AU)
The use of contact lenses has increased worldwide. Their current uses comprise optical correction as well as therapeutic purposes since they bring comfortableness and esthetics in a number of ocular diseases. It is expected that contact lenses-related complications will grow because bacterial keratitis is potentially severe and devastating for the eyeball. A literature review on the presence of corneal ulcers in contact lens wearers was made to describe the epidemiology and the ways of preventing this complication(AU)
