  • Prognosis • AR has favorable prognosis, retention of central vision until 5th -6th decade. • AD best prognosis, retention of central vision beyond 6th decade • XL worst prognosis with severe visual loss by the 4th decade. 27.[slideshare.net]
  • Prognosis The prognosis mainly depends on the progression of the visual loss: blindness occurs in almost all cases between 50 and 70 years of age. The documents contained in this web site are presented for information purposes only.[orpha.net]
  • Expectations (prognosis) The disorder will continue to progress, although slowly. Complete blindness is uncommon. Complications Peripheral and central loss of vision will eventually occur.[iloveicare.co.nz]
  • Extensive systemic and ocular evaluations are important and should be combined with genotyping in both familial and nonfamilial cases to determine the diagnosis and prognosis.[disorders.eyes.arizona.edu]
  • The mode of inheritance plays a key role in determining the prognosis of the disease. But in many cases, knowing about the exact genetic mode of inheritance is not possible [11, 13].[article.sapub.org]


  • Many of the diseases of the peripheral retina can be divided into trophic (nutritional), tractional, and a combination of trophic plus tractional etiologies.[books.google.it]
  • Etiology So far, mutations in five genes ( MYO7A , USH1C , CDH23 , PCDH15 , USH1G ) and one locus ( USH1E ) have been implicated in US type 1.[orpha.net]


  • Summary Epidemiology Prevalence is estimated at 1/30,000. US is the most common cause of hereditary combined deafness-blindness. Clinical description Onset usually occurs during childhood.[orpha.net]
  • Isolated cases, with no family history, also commonly occur Epidemiology Prevalence in all ages is approximately 1 in 4,000 [ 1 ] . Three types have been found determined by age of onset.[patient.info]

  • The short term goal of this proposed study is to determine the predominant molecular mechanism of P23H rhodopsin- related photoreceptor death, and identify novel therapeutics that prevents this retinopathy.[grantome.com]
  • The results from this study suggest that P23H-rhodopsin RP patients may have a pool of rod photoreceptor cells that are dystrophic but still viable, which could be targeted with therapeutic interventions that slow, prevent or even reverse degeneration[webvision.med.utah.edu]
  • These results also suggest that slow regeneration of P23H rhodopsin could prevent endogenous chromophore-mediated stabilization of rhodopsin in the retina.[ncbi.nlm.nih.gov]
  • Finding new ways to stimulate repair without damaging Inhibition of the FGF-receptor and MAPK signaling prevents the formation of MGPCs in damaged retinas.[brainscape.com]
