Choroidal Structural Changes Correlate With Neovascular Activity in Neovascular Age Related Macular Degeneration

Measurement of Choroidal Neovascular Area in Age-Related Macular Degeneration using Modified Otsu’s Thresholding Method

Introduction: Age-related Macular Degeneration (AMD) is one of the most important causes of irreversible  blindness in the developed world and  prevents the affected  person from  performing simple tasks such  as  reading,  driving  and  facial  recognition.  In  the  AMD,  new  blood  vessels  grow  underneath  the  retina  in  a  process  called  choroidal  neovascularisation  (CNV).  There  ...

Choroidal perfusion perturbations in non-neovascular age related macular degeneration.

AIM Choroidal perfusion, affected in age related macular degeneration (AMD), is difficult to objectively assess given the overlying retinal circulation. This study more objectively compared choroidal perfusion parameters in a group with non-neovascular AMD to an unaffected age matched control group. METHODS 21 non-neovascular AMD subjects and 21 age matched control subjects without evidence o...

Neovascular Age - Related Macular Degeneration

Ranibizumab in neovascular age-related macular degeneration

BACKGROUND Ranibizumab--a recombinant, humanized, monoclonal antibody Fab that neutralizes all active forms of vascular endothelial growth factor A--has been evaluated for the treatment of neovascular age-related macular degeneration. METHODS In this multicenter, 2-year, double-blind, sham-controlled study, we randomly assigned patients with age-related macular degeneration with either minima...

Systemic changes in neovascular age-related macular degeneration.

Age-related macular degeneration (AMD) is a leading cause of visual impairment in the aged population worldwide. The mechanisms underlying this multifactorial and heterogenic disease are complex and incompletely understood. There is increasing evidence to suggest that regulatory differences in the immune system are involved in the development of the various subtypes of AMD. The purpose of this ...
