Intravitreal bevacizumab for choroidal neovascularisation secondary to causes other than age-related macular degeneration.

Choroidal neovascularisation (CNV) is characterised by new blood vessel growth under the retina that usually results in significant visual impairment when the fovea is involved. Though CNV is more commonly associated with age-related macular degeneration (AMD), it can occur secondary to a variety of other diseases. Recent successes with anti-angiogenic therapies suggest that they may outperform other therapies for all types of CNV. As non-AMD-related CNV cases are rare, randomised controlled trials are often not possible. This review compares the less prevalent reports of non-AMD CNV and pools evidence on the success and limitations of a variety of therapies.
