What are the symptoms of optic nerve atrophy

What are the manifestations of myopic atrophy:

1, optic nerve nipple tilt and myopia: the height of myopia as the back of the eyeball bulge, the optic nerve oblique into the ball. As the side of the nipple (mostly temporal) backward shift, so that the optic disc under the ophthalmoscope lost normal round and oval. And its backward position connected, there are crescent-shaped spots, known as myopia arc, myopia arc contralateral papillary margin slightly brown, realm fuzzy, ridge-like uplift pull the arc. Stretch myopia medial white, sclera exposed, the outer side of the light brown, disappearance of the pigment epithelium, choroidal collapse caused by myofascicular arc lateral state is clear, but often with the posterior pole optic nerve atrophy into a piece. Myopia is located in the temporal lobe of the majority of cases, also located in the temporal or inferior temporal, rare in the nasal or lower side. When the temporal myopia arc outward, upward, downward continue to extend, can be around the entire optic papilla around, as the optic nerve around the choroidal atrophy.

2, leopard striatal fundus (eigroid fundus), the whole eye was slightly dark gray, with choroid plexus due to diffuse optic atrophy, capillary layer and vascular layer decreased or disappeared, orange-red blood vessels exposed, so that the eyes were leopard skin The

3, vision loss, can not be satisfied with the correction. The cause of vision loss is the extensive optic nerve atrophy of the retinal nerve epithelium. Macular hemorrhage can make a sudden loss of vision. Foerster-fuchs spot and macular atrophy after plaque formation, causing severe visual impairment, vitreous opacity to produce floaters. Vitreous is not completely separated from the retina due to incomplete retraction of the traction, and produce flash illusion.

4, the posterior pole of the optic nerve atrophy spots and lacquer-like damage. Choroidal no visible retinal atrophy spots white or yellowish white. Round or map-like, size, the number of different, isolated or integrated into large. Large atrophic spots can be seen in the optic nerve around the atrophic connection, including the optic disc and macula, including a huge atrophy. At the same time there are pigmentation, residual choroidal large blood vessels. Can also be seen in the branch or mesh white or yellow and white lines, lines and blood vessels similar to the lines, different width, the edge is not neat or jagged, similar to the old lacquer crack, so called paint damage.

5, macular part of the beam phase with macular hole. Ophthalmoscopy, the macula can be seen a clear boundary of circular erythema, diameter of about 1 / 3-1 / 2PD. Erythema around the contact retina slightly gray, if accompanied by limitations from the time, the surrounding iris. Slit lamp under the microscope, if the beam-like degeneration, the light section has a thin front beam tangent, if the hole, then the line is interrupted. Cracks on the outer wall of the hole and the surrounding retina.
