What is PCV in retina?

What is PCV in retina?

Polypoidal choroidal vasculopathy (PCV) is a disease primarily affecting the vascular layer of blood vessels in the choroid (pronounced CORE oid), resulting in damage to the overlying retina where the photoreceptor cells responsible for vision reside (see illustration).

What is IPCV eye?

Idiopathic polypoidal choroidal vasculopathy (IPCV), a rare retinal condition initially described in 1982, is characterized by retinal pigment epithelial (RPE) detachments associated with choroidal polypoidals.

What causes Cnvm?

CNVM occurs when new blood vessels start to grow in the choroid and break through the barrier between the choroid and the retina. When CNVM leak in the retina, they cause vision loss. CNVM are associated with many serious eye diseases, most commonly wet age-related macular degeneration.

What is subretinal fibrosis?

Subretinal fibrosis is defined as the development of either band-like or plaque-like areas of fibrosis underneath the retina due to choroidal neovascularization (CNV) or proliferation of retinal pigment epithelial (RPE) cells and Müller cells.

What is a PCV diagnosis?

In polycythemia vera (PCV), the body makes too many red blood cells, leading to a thickening of the blood. It can be associated with an elevated platelet count and an enlarged spleen.

What is retinal Angiomatous proliferation?

Retinal angiomatous proliferation (RAP), also referred to as type 3 neovascularization, is a distinct variant of exudative age-related macular degeneration (AMD) characterized by intraretinal neovascularization (IRN) with connections to either the retinal vasculature, the choroidal vasculature, or both [1].

What does the drug eylea do for the eye?

Generic Name: aflibercept Aflibercept is used to treat certain serious eye conditions (such as wet age-related macular degeneration, diabetic retinopathy/macular edema, macular edema following retinal vein occlusion). This medication can help preserve vision and prevent blindness.

What are Angioid streaks?

Angioid streaks are bilateral, narrow, irregular lines deep to the retina configured in a radiating fashion emanating from the optic disc, which result from breaks in a weakened Bruch’s membrane.

Is CNVM curable?

How do you treat CNVM? Of the two main forms of macular degeneration, wet and dry, wet macular degeneration is the only form with known, proven treatments. Those treatments include: Laser photocoagulation, Photodynamic Therapy, Macugen, Lucentis and Avastin injections.

How is CNVM diagnosed?

CNVM is diagnosed through a dilated eye exam followed by a diagnostic imaging procedure called fluorescein angiography. Treatment: Treatment depends upon several factors: size and location of the abnormal blood vessel membrane, and the amount of time since the symptoms began.

What is subretinal fibrosis in age related macular degeneration?

Subretinal fibrosis is a result of a wound healing response that follows choroidal neovascularization in neovascular age-related macular degeneration (nAMD).

What is CNV eye disease?

Choroidal neovascularization (CNV) involves the growth of new blood vessels that originate from the choroid through a break in the Bruch membrane into the sub–retinal pigment epithelium (sub-RPE) or subretinal space. CNV is a major cause of visual loss.

What is polypoidal choroidal vasculopathy?

Polypoidal Choroidal Vasculopathy: Definition, Pathogenesis, Diagnosis, and Management Polypoidal choroidal vasculopathy (PCV) is an age-related macular degeneration (AMD) subtype and is seen particularly in Asians.

What is polypoid mass with wide pedicle?

Biopsy of the polypoid mass was reported as a mucosal polyp rich in plasma cells. On direct laryngoscopy performed under general anesthesia, a smooth polypoid mass holding on the anterior commissure and the left cord with a wide pedicle was observed (Figure 1).

What is a polypoid lesion?

Microscopically, polypoid structures consisted of swollen myxomatous stroma lined by pseudostratified columnar epithelium. The lesion can have various presentations, including a polypoid enhancing intraluminal mass and a submucosal mass with or without perivesical fat involvement.

What is polypoidal CNV in PCV?

Polypoidal CNV is considered to be a unique form of CNV with characteristics distinguishing it from that of AMD. In PCV eyes studied by Uyama and colleagues, neither occult nor classic CNV was observed. 19 Also, there was no development of polypoidal CNV through the RPE into subretinal space.
