Regarding the type of cataract, cortical cataract
was most commonly seen in 50% cases followed by posterior subcapsular cataract in 28% cases.
Scores for cortical cataract
and PSC were based on weighted estimates of the degree of opacity of the lens area, as defined by a circular grid, divided into eight pie-wedge shaped peripheral areas and a central circular area overlaid on the photograph (Klein et al.
The LALES reported cortical cataract
as the most common lens opacity found in their population.
Polymorphic glutathione Stransferases as genetic risk factors for senile cortical cataract
is the next most common type, often affecting people who have diabetes.
21,22 In UK, cortical cataract
is the most prevalent (63%) type, followed by nuclear (41%) and posterior sub capsular cataract (24%).
The predominant type of cataract was early onset senile cortical cataract
in sixteen eyes, five eyes showed posterior subcapsular cataract, senile nuclear sclerosis was present in six eyes.
Age-related cataract diagnostic: A slit lamp was used to grading the cataracts as clinically into five subgroups, including Nuclear Sclerosis (NS), Posterior Sub Capsular (PSC), Cortical Cataract
(CC), Mixed Cataract (Mix C) and Mature Cataract (Mat C).
Sunlight and exposure to ultraviolet-B (UV-B) rays have been shown to be associated with cortical cataract
, clouding or opacity occurring first on the outer edges of the lenses.
1) Cortical cataract
2) Nuclear cataract 3) Subcapsular cataract.
The study, entitled "EphA2is associated with age-related cortical cataract
in mice and humans," will be published in the July 31 issue of PLoS Genetics.
15) patients with baseline impaired fasting glucose (IFG) had an increased risk of developing cortical cataract
Be able to identify anterior ocular pathology which may be related to UV exposure (for example UV keratoconjunctivitis, cortical cataract
, pterygium) and be able to offer appropriate advice to patients with those ocular conditions not requiring referral (Group 6.
