Congenital Fibrosis of Extraocular Muscles Type 5

DRS


Presentation

  • Figure 1: Patient at presentation.[meajo.org]
  • A number of other conditions and syndromes may present with infantile glaucoma, along with other ocular and/or systemic findings.[centogene.com]
  • (Age and Sex Distribution) Congenital Fibrosis of the Extraocular Muscles is a rare condition that is present at birth.[dovemed.com]
  • Germline mosaicism for a C T nucleotide substitution, as in the present case, can often be caused by methylation on the CpG dinucleotide.[molvis.org]
  • On the 1 st postoperative day, a residual exotropia of 7 and hypertropia of 7 was present in the right eye with the left eye fixing in primary position with a small right face turn.[ijo.in]
Surgical Procedure
  • The treatment for Congenital Fibrosis of the Extraocular Muscles may include: Eye glasses to treat eye focus issues Surgical procedures to fix eye misalignment and drooping upper eyelids (ptosis) The surgical procedures adopted will be specific to each[dovemed.com]
Myopathy
  • While CFEOM was classically thought to be a myopathy that resulted in muscle fibrosis, there is recent evidence to suggest that the fibrotic changes are secondary to defective innervations of the muscles during development ( Heidary 2008) .[webeye.ophth.uiowa.edu]
  • EXTRAOCULAR MUSCLES Anatomy and function MYOPATHIES Chronic progressive external ophthalmoplegia Muscular dystrophies Orbital inflammatory disorders RESTRICTIVE ORBITOPATHIES Orbital Graves disease Other restrictive syndromes DISORDERS OF THE NEUROMUSCULAR[neurology.mhmedical.com]
  • It is now considered that CFEOM disorders result from primary neuronal disease resulting in secondary myopathy.[disorders.eyes.arizona.edu]
Ptosis
  • While CFEOM 1 typically involves bilateral ptosis and ophthalmoplegia, CFEOM 3 has a more variable phenotype in which ptosis may be unilateral, ophthalmoplegia may be mild and some family members may be unaffected.[webeye.ophth.uiowa.edu]
  • Ptosis is part of both phenotypes. All patients have severe restrictions in ocular motility.[disorders.eyes.arizona.edu]
  • CFEOM is characterized by a variable restrictive external ophthalmoplegia, ptosis and eyes that are fixed in an abnormal position.[cags.org.ae]

Lagophthalmos
  • In fact, it might even result in disastrous corneal complications due to significant lagophthalmos that would invariably ensue.[meajo.org]
Chronic Progressive External Ophthalmoplegia
  • EXTRAOCULAR MUSCLES Anatomy and function MYOPATHIES Chronic progressive external ophthalmoplegia Muscular dystrophies Orbital inflammatory disorders RESTRICTIVE ORBITOPATHIES Orbital Graves disease Other restrictive syndromes DISORDERS OF THE NEUROMUSCULAR[neurology.mhmedical.com]

Treatment

  • Treatment Treatment Options: No treatment has been reported but it is likely that some cosmetic and head position improvement could be achieved with muscle and ptosis surgery.[disorders.eyes.arizona.edu]
  • Early treatment is important because of the risk of amblyopia. Surgery is the primary treatment option for strabismus and blepharoptosis.[ingentaconnect.com]
  • Upon diagnosis, treatment may be provided that include prescription eyeglasses and surgical procedures, as necessary The prognosis of Congenital Fibrosis of the Extraocular Muscles depends on the severity of the signs symptoms.[dovemed.com]

  • Thus, in the majority of cases, no treatment is necessary unless the patient has a marked head turn ( Fig. 82.6 ).[entokey.com]

Prognosis

  • Upon diagnosis, treatment may be provided that include prescription eyeglasses and surgical procedures, as necessary The prognosis of Congenital Fibrosis of the Extraocular Muscles depends on the severity of the signs symptoms.[dovemed.com]
  • The outlook is guarded, and, as the condition is rare, even the most experienced pediatric ophthalmologist can offer little in the way of a confident individual prognosis.[entokey.com]

Etiology

  • While CFEOM syndromes was classically thought to be due to a congenital abnormality of muscle development, I is now considered to have a neurologic etiology and the term congenital Cranial dysinnervation disorders (CCDD) was coined to encompass not just[meajo.org]
  • Regardless of clinical variations, they are being grouped first by genetic etiology and then by clinical differences.[ojoonline.org]
  • (Etiology) There are 4 forms of Congenital Fibrosis of the Extraocular Muscles and the nature of their cause is described below: CFEOM type 1 and type 3 are caused by the inheritance of specific autosomal dominant genes.[dovemed.com]
  • Three novel mutations in KIF21A highlight the importance of the third coiled-coil stalk domain in the etiology of CFEOM1. BMC Genet 2007;8:26. [18]. Yang X, Yamada K, Katz B, et al.[journals.lww.com]

Prevention

  • Congenital fibrosis of the extraocular muscles prevents the normal development and function of these muscles. As a result, affected individuals are unable to move their eyes normally.[ghr.nlm.nih.gov]
  • They also scoff at any idea fake rolex that natural alternatives will help or prevent seizures. They will not teach you how to control seizures naturally. He also made it sound like it was impossible to control seizures naturally. .[nrs-law.com]
  • Daniell et al . [6] has described supramaximal horizontal recess-resect procedure with adducting traction sutures left in situ for 6 weeks to prevent the eye from getting abducted and thus reducing the chance of a postoperative exotropic drift.[ijo.in]
  • Point mutations affecting motor domains of other kinesin family genes have been reported in spastic paraplegia ( KIF5A ) and Charcot-Marie-Tooth disease ( KIF1Bβ ) and have been shown to prevent stimulation of the motor adenosine triphosphatase by microtubule[jamanetwork.com]
