![]() The cause of this bilateral optic nerve abnormality is not known. In the normal case, the two veins drain centrally in the optic nerve (see normal anatomy photo). The left eye frame shows both the superior and inferior hemi-central retinal veins draining outside of the optic nerve margins (blue circles), draining into the choroidal veins that circle the optic nerve (black arrows, ring of Zinn). Terminologies of Pathological Myopia:-1)Degenerative Myopia. The purple arrow shows the looping of the superior hemi-central retinal vein, which drains to a peripapillary vein emptying into a choroidal vein. Methods: Clinical presentation, laboratory and imaging findings, treatment and outcome for all cases of recurrent ipsilateral, recurrent contralateral, and bilateral simultaneous cases of facial paralysis are reviewed. If the Myopia is bilateral, the child will usually display some noticeable difficulty in seeing distant objects and will hold things very close for viewing. The inferior hemi-central retinal vein drains into this pit-like structure, which is abnormal. The yellow circle in the right eye frame shows an optic pit-like abnormality. The green arrows in both frames indicate the central retinal artery, which brings blood into the retina through the nerve. Upon examination, the diagnosis of pathologic myopia was confirmed, but also found were abnormal patterns of retinal venous drainage in both eyes. This 40 year old male presented for evaluation of myopic degeneration in both eyes.
