<prompt> Choroidal neurovascularization is seen in all except aEURTraumaAngiod streakMyopiaHypermetropia  <response>: Hypermetropia Choroidal neurovascularization CNV It is inappropriate ingrowth of blood vessels and accompanying cellular infiltrate originating in the choroid it extends through Bruchs membrane to proliferate under retina, the retinal pigment epithelium or both. It is a common end stage process in a number of different diseases leading to severe visual loss. Conditions associated with it are ? - Age-related macular degeneration ARMD-most significant - Angioid streaks Choroidal rupture trauma - Pathological myopia - Chorioretinal scars - baraocular inflammation - Chorioretinal dystrophy Signs symptoms? - Decreased central visual activity - Metamorphosia apparent distoion of objects - Intraretinal, subretinal pigment epithelium hemorrhage - Macular oedema - Subretinal.fluid Associated features ? - Lipid exudation - Detachment of the retinal pigment epithelium - Retinal pigment epithelium tear - Scarring Diagnosis - Diagnosis of CNV is done by fluorescein angiography with indocyanine green angiography Treatment options - Laser photo coagulation - Photodynamic therapy - Radiation external beam radiotherapy - Surgery submacular surgery - Pharmacological therapy - Intravitreal triamcinolone long standing steroid
