1, Objective:To evaluate the direction value of perimetry in diagnosing and curing the acute retrobulbar neuritis.

2, Conclusion B/Y perimetry is a relatively sensitive method for detection of the early visual field loss in POAG.

3, Objective To study the presentation of frequency doubling perimetry (FDP) in patients with primary open angle glaucoma(POAG).

4, Perimetry has been widely used in the examination of visual function, which has specific clinical value of application.

5, As a testing method of visual function, perimetry is important tool to the diagnosis, selection of treatment and follow up of glaucoma.

6, Supra-threshold perimetry has limited specificity, and FDP might be a promising method in screening glaucoma with relatively good specificity.

7, Visual acuity , perimetry, P-VEP and CSF were performed in the two groups at the first view.

8, Conclusion:The direction value of perimetry is very good in diagnosing and curing the acute retrobulbar n...

9, Methods 50 eyes of 45 anterior ischemic optic neuropathy patient were checked by fluorescence fundus angiography , perimetry and so on, the result were analyzed.

10, Methods 237 patients finally diagnosed diabetes were examined by fluorescence fundus angiography, VEP and examination of visual field; perimetry, the information of the optic neuropathy were analyzed.

11, Metabolic factors play an important role in visual field loss. These also reveal the automated perimetry is an effective and potential examination in DR patients.

12, The entire ophthalmological examinations gave normal results except for the visual field examinations. Goldmann perimetry revealed a left homonymous inferior quadrantanopia.

13, If anything looks abnormal,(http:///perimetry.html) the doctor will measure the extent of your visual field by a painless method called perimetry.

14, Perimetry is an important method to check the visual function, and the automatic computerized visual field analyzer is an effective instrument for perimetry.

15, With the progress of visual and optical theories, modern examination technique and information technology, perimetry continues to develop and improve.
