We present an 8-month-old boy with severe retinal detachment from familial exudative vitreoretinopathy (FZD4 exon 1 deletion). [ncbi.nlm.nih.gov]

More recently, Errais et al. (2008) presented what could be considered the first comorbid association of FEVR with hyaloid artery persistence. [cags.org.ae]

Clinical features FEVR presents with bilateral expression that may be asymmetrical. [institut-vision.org]

Because of our interest in the genetic basis of FEVR, we have examined our Japanese patients with FEVR to determine whether TSPAN12 mutations were present in them. [entokey.com]

• Neglect

  FEVR in asymptomatic individuals can be detected using fluorescein angiography ( Figure 5 ), but mild changes in the peripheral retina may be neglected, which might partly contribute to the nonpenetrance in a few families. [molvis.org]

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

Treatment and prognosis Early or mild FEVR (Stage 1, Figure 1) without leaking blood vessels (exudation) is generally managed by observation without treatment. [asrs.org]

Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. [rarediseases.info.nih.gov]

Due to the wide variability of symptoms, we strongly encourage you to discuss your questions regarding your child's prognosis with her treating physician. [2] Early treatment can improve the long-term prognosis/outlook for children with FEVR. [rarediseases.info.nih.gov]

Management, follow-up & prognosis Management The main objective is the early diagnostic and treatment of the disease. [institut-vision.org]

Treatment and prognosis Early or mild FEVR (Stage 1, Figure 1) without leaking blood vessels (exudation) is generally managed by observation without treatment. [asrs.org]

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]

The anterior form has a worse prognosis than the posterior form, and its treatment requires more complex surgical procedures. [ncbi.nlm.nih.gov]

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]

Hence, it is possible thatthe two disorders have a similar etiology. [docslide.us]

The cloning of the ND gene has made it possible to investigate the etiology of ND, as well as seve ral other clinically similar conditions. [eurekaselect.com]

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

They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]

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]

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]

This condition affects the retina, the light-sensitive tissue that lines the back of the eye, by preventing blood vessels from forming at the edges of the retina. This reduces the blood supply to retina. [rarediseases.info.nih.gov]

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]

Medical treatment has been directed toward preventing inflammation, the first phase of the wound healing process, and inhibiting cell proliferation, the second phase. [ncbi.nlm.nih.gov]
