77 Possible Causes for Weakness of Orbicularis Oculi Muscles

  • Myopathy and Diabetes mellitus

    […] of orbicularis oculi muscle 60 33 occasional (7.5%) Occasional (29-5%) HP:0012507 24 tip-toe gait 60 33 occasional (7.5%) Occasional (29-5%) HP:0030051 25 sensorineural hearing[malacards.org] […] distal lower limb amyotrophy 60 33 occasional (7.5%) Occasional (29-5%) HP:0008944 22 sternocleidomastoid amyotrophy 60 33 occasional (7.5%) Occasional (29-5%) HP:0012036 23 weakness[malacards.org]

  • Ectropion

    Various causes: involutional (age-related degeneration) most common horizontal lid laxity weakness of pretarsal part of orbicularis oculi muscle weakness of medial and lateral[college-optometrists.org]

  • Bell's Palsy

    SIGNIFICANCE: Our findings are in agreement with an animal model of blepharospasm that suggests a combined role of weakness of the orbicularis oculi muscle and a dysfunction[ncbi.nlm.nih.gov] Weakness of the orbicularis oculi muscle and resulting incomplete eye closure may be associated with corneal injury.[curlie.org]

  • Muscular Dystrophy

    Mild involvement of the facial musculature (particularly of the orbicularis oculi and oris muscles) is often present.[orpha.net] Early weakness of neck flexion is present in all patients.[orpha.net] Mild proximal weakness develops more than ten years after the onset of the disease.[orpha.net]

  • Blepharoptosis

    For patients with weak eyelid excursion (2 to 4 mm), the interdigitated orbicularis oculi-frontalis muscle flap was the procedure of choice.[ncbi.nlm.nih.gov] When the eyelid excursion was moderate ( 4 mm), the orbicularis oculi muscle flap was used. For patients with minimal or weak eyelid excursion ([ncbi.nlm.nih.gov] When eyelid excursion is moderate (3 to 5 mm), the orbicularis oculi muscle flap technique was effective.[ncbi.nlm.nih.gov]

  • Tick Paralysis

    The stimulated jitter analysis of the orbicularis oculi muscle showed normal jitter with no blocking.[ncbi.nlm.nih.gov] METHODS: A 7-year-old girl with acute onset proximal muscle weakness and an engorged dog tick attached to her scalp was evaluated.[ncbi.nlm.nih.gov] RESULTS: The routine motor nerve conduction study showed normal compound muscle action potential amplitude.[ncbi.nlm.nih.gov]

  • Multifocal Motor Neuropathy

    Here we described a 32-year-old woman with progressive weakness of hand muscles associated with weakness of orbicularis oculi muscles and fasciculations of tongue.[marmaramedicaljournal.org] On neurological examination orbicularis oculi muscles were bilaterally weak and there were fasciculations on her tongue.[marmaramedicaljournal.org] We found a moderate neurogenic involvement of orbicularis oculi, sternocleidomastoid and lingual muscles.[marmaramedicaljournal.org]

  • Foreign Body Aspiration

    An electromyographic study of the right orbicularis oculi muscle showed a 50% decrement in response to repeated stimuli.[anesthesiology.pubs.asahq.org] Clinical examination after his extubation confirmed global muscular weakness and ptosis.[anesthesiology.pubs.asahq.org]

  • Distal Myopathy

    Mild involvement of the facial musculature (particularly of the orbicularis oculi and oris muscles) is often present.[orpha.net] Early weakness of neck flexion is present in all patients.[orpha.net] Mild proximal weakness develops more than ten years after the onset of the disease.[orpha.net]

  • Chronic Progressive External Ophthalmoplegia

    Weakness of extraocular muscle groups including, the orbicularis oculi muscle as well as facial and limb muscles may be present in up to 25% of patients with CPEO.[en.wikipedia.org] Patients with myasthenic ptosis will also frequently have orbicularis oculi muscle weakness that may manifest as lagophthalmos. Testing for MG varies between centers.[reviewofophthalmology.com] Ptosis associated with CPEO may be corrected with surgery to raise the lids, however due to weakness of the orbicularis oculi muscles, care must be taken not to raise the[en.wikipedia.org]
