What finding is most expected in a female with long-standing myopia and newer onset presbyopia?

In evaluating a female with long-standing myopia who has developed newer onset presbyopia, the expectation of sharp disc margins is significant. Sharp disc margins indicate that there is no swelling or significant pathology affecting the optic nerve head. In the context of myopia, particularly when it is long-standing, the eyeball is often elongated, which can lead to changes in the retina and increased susceptibility to issues such as retinal detachment. However, the presence of sharp disc margins suggests that despite the challenges associated with myopia, the optic nerve is functioning well and there is no evidence of papilledema or other optic neuropathies.

Furthermore, presbyopia is a refractive change related to aging, specifically the loss of accommodation due to stiffening of the lens. While it is a common occurrence, it does not necessarily correlate with pathological changes to the optic nerve or the condition of the ocular media, which helps emphasize the hallmark of having sharp disc margins in this scenario. This makes the finding of sharp disc margins a key indicator of a stable ocular situation despite the progression of myopia and the onset of presbyopia.
