AIM: To report the clinical manifestations of localized peripapillary detachment in pathologic myopia and to evaluate its underlying associations and causes.METHODS: From December 2002 to January 2004, 10eyes from 7 patients with high myopia were identified to have localized peripapillary detachment by optical coherent tomography (OCT). The features were described together with the fundus fluorescein angiography, indocyanine green angiography and multifocal electroretinogram.RESULTS: Localised peripapillary detachments did not cause any symptoms by themselves and all the lesions were recognized because of other ocular problems. The areas of peripapillary detachment were all located within the posterior staphyloma. In the 5 eyes with type 1 staphyloma, the locations of detachment were all in the nasal half of the peripapillary area. In the other 5 eyes with type 2 and 3 staphyloma, the locations of detachment were all in the non-nasal peripapillary area. The difference between these two groups was statistically significant (Fisher's exact test, ,P= 0.01).CONCLUSION: Peripapillary detachment is probably a benign complication of posterior staphyloma in pathologic myopia. The site of peripapillary detachment is affected by the location of staphyloma and OCT is important in making the diagnosis.

Objective To describe localized peripapillary detachment in highly myopic eyes, and to analyze the possible cause of this newly recognized fundus lesion. Methods From December 2002 to January 2004, 10 eyes from 7 patients with high myopia were identified to have localized peripapillary detachment by optical coherent tomography (OCT). The features were described together with the fundus fluorescein angiography, indocyanine green angiography and multifocal electroretinogram. Results Peripapillary detachment was not the reason for any patient to be referred for examinations. The reasons of vision decrease or lower BCVA were relatively severe myopic chorioretinal changes, CNV, pre macular membrane formation, and amblyopia. The areas of peripapillary detachment were all located within the posterior staphyloma. The length of the detached retina was undoubtedly shorter than that of the corresponding RPE and inner layer of choroids, which attached to sclera, on OCT. Conclusion Peripapillary detachment is probably a benign complication of staphyloma

The bladder meridian of foot-taiyang is considered as key of six meridians and the yang of the yang, which is the pivot of transportation for qi and blood in the meridians and zang-fu. The running route and treatment characteristic of bladder meridian is closely related with chronic fatigue syndrome (CFS). The bladder meridian belongs to brain and connects with governor vessel, which has a close relationship with zang-fu function, quality of sleep and fatigue. Besides, the running route of bladder meridian is highly consistent with the surface projections of important anatomical structures such as muscle, nerve and sympathetic trunk, etc. Therefore, regulating the meridian-qi of bladder meridian can harmonize five-zang and calm the mind, but also effectively relieve physical and mental fatigue in CFS.
