Ophthalmoscopic variations and diagnostic problems
نویسندگان
چکیده
The clinical significance and ophthalmoscopic features of angioid streaks have received considerable attention in the ophthalmic literature (Paton, I962; Paton, 1972; Connor, Juergens, Perry, Hollenhorst, and Edwards, I96I). Angioid streaks usually have a characteristic ophthalmoscopic appearance and diagnosis is easy. In some instances, however, they may be subtle or may simulate other more common fundus conditions and the diagnosis may be more difficult. The ophthalmoscopic variations are discussed in this report with some of the more common diagnostic problems which occurred in a large series of patients with angioid streaks. These problems may be overcome by recognizing the variable clinical manifestations of this condition.

A Class of new methods based on a septic non-polynomial spline function for the numerical solution of problems in calculus of variations is presented. The local truncation errors and the methods of order 2th, 4th, 6th, 8th, 10th, and 12th, are obtained. The inverse of some band matrixes are obtained which are required in proving the convergence analysis of the presented method. Convergence anal...
