WebDec 24, 2024 · The increased BM strain may cause an enlargement of Bruch’s membrane opening (BMO) of the optic nerve head, with the subsequent development and enlargement of parapapillary gamma zone as BM-free parapapillary zone. The increased strain within BM and RPE may also cause lacquer cracks (LCs) as linear breaks in the RPE and / or BM. WebThe reason for a nonglaucomatous optic nerve damage in highly myopic eyes may be that the development of parapapillary gamma zone in the temporal region increases the distance between the fovea and the optic disc. It may lead to a stretching of the retinal ganglion cell axons which connect the fovea with the optic disc.
