1, Objective: To investigate the difference of optic disk and retinal microcirculation blood flow in different level myopic patients.

2, First, the red basic image of optic disk was obtained, then automatic segmentation of optic disk was done based on the obvious edge features of the basic red image.

3, This invention belongs to storage techniques in optic disk domain.

4, This paper is about the problem of segmentation of eyeground optic disk image, based on method of computer image processing.

5, Funduscopic examination reveals retinal hemorrhages extending outward from the optic disk and may cover the whole fundus, giving a "blood and thunder appearance" (shown).

6, Objective: To discover the etiology , pathology , clinical course, therapy and prognosis of optic disk vasculitis.

7, The article summarizes the achievements of the study progress about the normal structure of optic disk lamina and pathological alteration in glaucoma and looks into the future.

8, Combined with the eyeground examination, the image characteristics of eye-associated structures were observed and its value on the diagnosis of optic disk edema was evaluated.

9, Define the following term: astigmatism, binocular vision, focal length, lens accommodation, optic disk, papillary constriction, retinal field, visual field.
