9,821 Possible Causes for Loss of Light Reflex of the Tympanic Membrane

  • Upper Respiratory Infection

    Bright transmission of light suggests a normal air-filled sinus; absent light transmission suggests the presence of fluid.[emedicine.medscape.com] Diphenhydramine syrup, Robitussin DM, Delsym 12-hour) reduce sensitivity to the cough reflex so you cough less. Good for coughs that prevent sleeping.[uhs.umich.edu] The signs include bulging with or without erythema of the tympanic membrane (TM), and the symptoms may include otalgia, irritability, otorrhea, and fever.[pediatrics.aappublications.org]

  • Acute Gastroenteritis

    Acute gastroenteritis, known colloquially as a stomach bug, is an intestinal inflammation following an infection that affects the mucous membranes present in the stomach and[health.ccm.net] Thirst, skin turgor, mucous membranes, blood pressure and urine output are suitable parameters to continuously evaluate the current state of hydration.[symptoma.com] Same ORS solution given to match stool losses and purging losses.[wellcomeopenresearch.org]

  • Insect Bite

    If you are traveling solo from location to location, the net should be compact, light, and easy to set up.[travmed.com] Under conditions of high temperatures or humidity, which increases loss of repellent from the skin surface, or when there is intense insect-biting activity, higher concentrations[travmed.com]

  • Acute Otitis Media

    Note bulging of the upper tympanic membrane (pars flaccida) due to raised pressure in the tympanic cavity with pulling in at the umbo ie the malleolal attachment. [radiopaedia.org] Ears: clean canals bilaterally, left tympanic membrane pearly grey with light reflex and visible bony landmarks.[npstudent.com] Mild conductive hearing loss The tympanic membrane appears retracted, congested (especially the pars flaccida) signs of fluid behind the tympanic membrane -Stage of acute[quizlet.com]

    HBO requires daily treatments for several weeks and side effects include oxygen toxicity, barotrauma, and tympanic membrane perforation 16.[slideshare.net] […] and tympanic membrane visible Grade II Debris in ear canal (not completely occluded) and erythematous ear canal, tympanic membrane may be partially obscured Grade III The[teachmesurgery.com] Otoscopy revealed an intact tympanic membrane with less of a bulge.[casereports.in]

  • Viral Lower Respiratory Infection

    A positive reaction releases light, which is captured on a Polaroid high-speed detector instant film within the imaging device.[mja.com.au] Bullous myringitis (inflammation of the tympanic membrane with bullae ) is uncommon, occurring at most in about 5% of patients, but has a high positive predictive value for[microbiologybook.org] membrane (TM), and pain in the ear.[dovepress.com]

  • Influenza

    Viral replication in combination with the immune response to infection results in the destruction and loss of the mucosal epithelial cells.[news-medical.net] Bright light may make the headache worse. At first, respiratory symptoms may be relatively mild.[merckmanuals.com] Although appetite loss , nausea, vomiting, and diarrhea can sometimes accompany influenza infection, especially in children, gastrointestinal symptoms are rarely prominent[medicinenet.com]

    The sympathetic response below the level of injury is uninhibited, producing severe vasoconstriction and reflexive bradycardia.[emedicine.medscape.com] Adhesins are bacterial surface structures that enable attachment to host membranes.[emedicine.medscape.com] The person is given a light anesthetic and the bladder is filled with water.[sutterhealth.org]

  • Tympanic Membrane Perforation

    CONCLUSION: The conductive hearing loss resulting from a tympanic membrane perforation is frequency-dependent, with the largest losses occurring at the lowest sound frequencies[ncbi.nlm.nih.gov] Tympanic membrane perforation can be suspected with a history of ear trauma, ear tubes, frequent ear drainage or hearing loss.[nationwidechildrens.org] Figure 1 Right tympanic membrane perforation.
