Item Relationship Between Corneal and Refractive Astigmatism(ALNeelain University, 2002-08) Madiha Sid Ahmed AliAllS'I'RAC'l' The aim of this study was to find arelationship between the corneal and refractive astigmtism , (RA) & (CA) and to show if it is possible to derive the subjective astigmatism (SA) from kcralomctric reading (KR). SO subjects(lOO eyes) were examined using Shin-nippon 9000 autorelkeratometer for RA and CA measurements , and subjective results were obtained . The difference in location of the axes of RA with CA and CA with SA was approximately same .There was no fixed relation in the axes . RA and SA axes exhibited small variation , §i5° difl”crcnce was the most (39.3%) , followed by £il0° (22.7%). l The dioptric difference of i0.75D and less between RA and CA was (95.8%) (95.7%) between CA and SA and (95.7%) between RA and SA. 20.1% for RA with CA , 25.6% for CA with SA and 18.3% for RA with SA were the difference of si0.50D. CA was agreed RA in l8.2%,with SA in 19.2% while RA and SA agreed in 32.6% . Generally , amathematical formula for the relation of RA with CA could not be drown . \ Key words : refractive , corneal, subjective,astigmatism . llItem fuzzy traffic lights control(200) manal osman mohammedItem an approach to evaluate an object-oriented database management system(2002) khalid mohamed osmanItem problem solving the search for solution teehniques(200) jamal saad mohamedItem methods to find minimum for function of one variable(2003) Hytham ahmed abdallaItem an approach to develop intelligent systems(200) hwida gaffer bakhietItem search engine and agent community algorithm(2004) hussam sulieman al btoushItem example-based knowledge engineering(2003) hietham ahmed elhadiItem optimization using genetic algorithms(2003) gfary hassan haj hamadItem use of mobile in exit visa as the part of the e-government project(2007) elamin mohamedelamin
