The most characteristic abnormality of this genotype was a slowed rod branch of dark adaptation, which was present regardless of the extent or severity of disease. [ncbi.nlm.nih.gov]
Presently, there is limited information on the mechanism(s) that detect and degrade rhodopsin. [surface.syr.edu]
Here, we present a spacer-mediated allele-specific knockout approach that utilizes both SpCas9 variants and truncated single guide RNAs (tru-sgRNAs) to achieve efficient discrimination of a single-nucleotide mutation in rhodopsin (Rho)-P23H mice, a model [biorxiv.org]

Colorblindness
Rod monochromacy, a form of colorblindness due to absent or nonfunctional cone photoreceptors, can be caused by mutations in the cone cGMP-gated cation channel. [ommbid.mhmedical.com]

Visual Field Reduction
field reduction can be as severe in heterozygous females as in hemizygous males. [jmg.bmj.com]
Treatment
Make optimal use of the newest drug therapies, including Anti-VEGF treatment for wet ARMD and bevacizumab treatment for complications of diabetes. [books.google.com]
The molecular mechanism of P23H rhodopsin autosomal dominant retinitis pigmentosa (adRP) is still not clear, and currently there is no effective treatment for this retinal degenerative disease. [grantome.com]

Prognosis
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]
Etiology
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]
Epidemiology
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]

Prevention
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]
