CLINICAL COURSE The FEVR patient population is characterized by a spectrum of disease presentation, including range of age at presentation, gestational age, and birth weight. [entokey.com]

Methods:Findings in five affected members of a family in which the X-linked mode of inheritance of familial exudative vitreoretinopathy is present are discussed. [journals.lww.com]

• Indecisiveness

  Seven causative mutations and five possibly causative but indecisive variants were examined. [ncbi.nlm.nih.gov]

Evaluating TSPAN12 large deletions and duplications should be considered in FEVR screening and diagnosis as well as in routine genetic workups for FEVR patients. [ncbi.nlm.nih.gov]

These patients are often family members of a patient with advanced disease, who are identified during the screening workup for suspected FEVR. [reviewofophthalmology.com]

Intravitreal injection of pegaptanib sodium is a potential treatment option for patients with FEVR and worsening exudation despite treatment with standard therapy. [ncbi.nlm.nih.gov]

— Widefield angiography is essential in diagnosing familial exudative vitreoretinopathy, but treatment type and efficacy depend on the stage of the disease, according to a speaker here. [healio.com]

The prognosis for infants with FEVR is extremely poor and the long-term prognosis for patients with a later onset of the condition is guarded. [ncbi.nlm.nih.gov]

Diagnosis and Prognosis: The diagnosis can only be made by an ophthalmologist by direct examination of the eye. The prognosis is unpredictable for some patients have minimal or no symptoms while other eyes become blind. [disorders.eyes.arizona.edu]

Prognosis The clinical presentation of FEVR is highly variable. The usual course of the disease has not been well established making the prognosis difficult to ascertain. Progressive loss of vision is reported in severe cases. [orpha.net]

FEVR eyes that present in the first year of life have a much worse prognosis. Benson ( 3 ) noted that children who presented in the first 3 years of life had a worse prognosis. [entokey.com]

Etiology Mutations in the FZD4 (11q14-q21) or LRP5 (11q13.4) genes have been associated with autosomal dominant FEVR as well as ZNF408 (11p11.2). LRP5 has also been associated with recessive cases. [orpha.net]

These characteristics help to clearly identify ROP as a causative etiology. The classic finding in FEVR is peripheral retinal capillary nonperfusion. [reviewofophthalmology.com]

Etiology and pathogenesis FEVR primary pathology is a premature arrest of retinal vasculogenesis, leading to incomplete vascularisation of the peripheral retina. The secondary complications are mainly due to retinal ischemia. [institut-vision.org]

Epidemiology, onset & clinical features Epidemiology The disease is often described as rare or very rare, through the exact prevalence remains unknown. [institut-vision.org]

Summary Epidemiology The prevalence of FEVR is unknown. It is usually inherited dominantly and many asymptomatic individuals may not come to medical attention as a result of non-penetrance. [orpha.net]

Six genes so far have been implicated in FEVR: FZD4[6][7], NDP[8][9], LRP5[7][10], TSPAN12[11][12][13], KIF11[14][15] and ZN408. [16] Epidemiology FEVR is described as a rare inherited disorder. The prevalence has not been reported yet. [eyewiki.aao.org]

The pathophysiologic mechanism, natural history, and optimal treatment of this disease are matters of debate. With active surgical management, three of the four eyes which presented to us for treatment have visual acuity of 20/30 or better. [ncbi.nlm.nih.gov]

These factors have been shown to be the regulators of the pathophysiological pathways of retinal vascular development. [e-tjo.org]

Genetic Pathophysiology Scientists have now linked 6 distinct genes that can lead to FEVR including FZD4[6][7], NDP[8][9], LRP5[7][10], TSPAN12[11][12][13], KIF11[14][15] and ZN408. [16]. [eyewiki.aao.org]

Prevention of the primary manifestations of the disease is not possible at present, but prevention and treatment of manifestations mostly related to the neovascularization process may be achieved by prophylactic cryotherapy or argon laser. [institut-vision.org]

Alteration prevents the formation of blood vessels in the retina margins, reducing blood supply to the tissue. Signs and symptoms of familial exudative vitreoretinopathy vary widely, even within the same family. [ivami.com]
