Older patients had higher rates of blindness at presentation (P 0.005); blindness and visual impairment rate at presentation were higher in males than females (P 0.029). [dovepress.com]

What is the prognosis for retinitis pigmentosa? The prognosis varies widely among RP patients, with some retaining 20/40 or better vision in at least one eye and others eventually losing all useful central vision. [medicinenet.com]

Prognosis The prognosis for patients with retinitis pigmentosa is dependent on the age of onset, and pattern of inheritance. Early-onset symptoms and severe vision loss and night blindness are expected with the autosomal recessive form of RP. [statpearls.com]

Prognosis Except for mild cases or sectorial RP, most cases progress to legal blindness (visual acuity 1/20 and visual field 5 degrees). The documents contained in this web site are presented for information purposes only. [orpha.net]

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]

According to some studies, individuals with adRP have the best prognosis, with the majority of those younger than age 30 years having a visual acuity of 20/30 or better. [institut-vision.org]

Etiology and Pathophysiology Mutations in the rhodopsin gene account for 30% of cases of autosomal dominant RP. Another 4–6% of autosomal dominant RP is caused by a mutation in the gene for a photoreceptor protein peripherin/RDS. [unboundmedicine.com]

Summary Epidemiology Prevalence of RP is reported to be 1/3,000 to 1/5,000. No ethnic specificities have been reported although founder effects are possible. Clinical description Retinitis pigmentosa is slowly progressive but relentless. [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]

Epidemiology Nonsyndromic retinitis pigmentosa has a worldwide prevalence of about one in 5000, and carriers number about one in 1000. Males are affected slightly more often than females due to the X-linked form expressing more frequently in males. [statpearls.com]

Etiology and Pathophysiology Mutations in the rhodopsin gene account for 30% of cases of autosomal dominant RP. Another 4–6% of autosomal dominant RP is caused by a mutation in the gene for a photoreceptor protein peripherin/RDS. [unboundmedicine.com]

Pathophysiology As previously mentioned, there are multiple genetically directed mechanisms for the progress of retinitis pigmentosa. Apoptosis is essentially physiologic programming for cell death, which can be triggered by a genetic mutation. [statpearls.com]
