Prevalence of the different types of age-related cataract in Upper Egypt
Mai Mahmoud Mohammed;
Abstract
A cataractis any opacity of the natural crystalline lens that degrades the optical quality. Cataract is a multifactorial disease age has been established as a major risk factor for cataract which increase in prevalence with age. The World Health Organization identifies cataract as the cause of 50% of world blindness.
Previous studies have reported that cataract increase in prevalence with agewith an estimated 17 million individuals bilaterally blind due to cataract.
The effect of age can be expected to grow and will increase dramatically in the coming decade. The age effect was not linear for all three types.
Age-related lens changes are typically described as three distinct morphological entities: nuclear,cortical, and posterior subcapsular cataracts.
Cataract can be treated most often with excellent outcomes through surgery with IOL implantation.
The examination was done to 2543 who came to Qous outpatient clinic; 183 patients had cataract, 101 patients had age related cataract and 83 patients have secondary cataract excluded by age below 40 years, history of diabetes, trauma, glaucoma and other ocular diseases such as retinitis pigmentosa and high myopia.
This study was conducted on 101 patients who had age related cataract, 26 (25.7%) male and 75 (74.3%) female from age group above 40 years. History is taken to patient presented with cataract in ophthalmology outpatient clinic in Qous hospital in Qena (upper Egypt) for 6 months.
Visual acuity was tested and refraction then IOP is measured.Fundus examination is done by direct and indirect ophthalmoscope to examine retina, its vascularity and optic disc. eye photography is taken to each cataractous lens.
The result ofthis study revealed that prvelence of age related cataract was 101patients have age related cataract (after exclusion criteria) and 82 patients who had secondary cataract due to any cause.Males who had immature cataract were 4 (15.4%), hypermaturewere2 (7.7%) and mature cataract were20 (76.9%), while female who had immature cataract were9 (12%), hypermaturewere17 (22.9%).
On examination patients who have bilateral cataract were5, 1male and 4 female. And 96 had unilateral cataract, 25 male and71 female.According to type of cataractmales who had cortical cataract were17 (65.4%) but female were39 (52%).while males had nuclear cataract 3 (11.5%) but female were8 (10.7%).males who had PSC were2 (7.7%) while females were6 (8%). Males who had mixed cataract were4 (15.4%) and females were22 (29.3%).
Age-relatedcataract was a common finding in patients over 51 years of age with cortical cataract being the predominant type of cataract. Female was associated with an increased prevalence ofcortical cataract.
