Spectral thresholds in macular degeneration.

Spectral thresholds in macular degeneration.

Spectral sensitivities were measured in 18 normal eyes, 9 eyes in patients with senile macular degeneration, 4 patients with Stargardt's juvenile macular degeneration (JMD), and 2 patients without conclusive signs--that is, genetic or morphological abnormalities--to indicate the cause of loss of central vision. Spectral sensitivity, testing for which included measurements on white, yellow, purp...

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  ...

Association of CFI gene polymorphism with age related macular degeneration in Northwest of Iran

Background & Aims: To investigate the association of CFI p.Gly119Arg polymorphism with Age-related macular degeneration (AMD). Materials & Methods: In this case-control study, the association of p.Gly119Arg polymorphism in CFI gene was investigated in 65 patients suffering from AMD and150 healthy age, sex and ethnicity matched unrelated people as control group. Both of the case and cont...

the genetics of age-related macular degeneration

age-related macular degeneration (amd) is the leading cause of blindness in old subjects. it is a multifactorial disease with both environmental and genetic factors playing some role in its pathogenesis. similar to many other genetic diseases, the inheritance pattern of amd does not fit into simple mendelian rules. these diseases are caused by the presence of multiple genetic factors and are ca...
