Irregular Peripheral Vision Movement and Optic Nerve Edema - Ophthalmology

More Info

---

Understanding the symptoms you are experiencing, particularly irregular peripheral vision movement and optic nerve edema, is crucial for determining the underlying cause and appropriate treatment. Based on your description, it seems that you have been experiencing these visual disturbances for about six months, initially affecting only your right peripheral vision but now extending to the lower central vision as well. You have undergone several tests, including Optical Coherence Tomography (OCT) and visual field assessments, which revealed mild edema of the optic nerve without any apparent retinal or macular pathology.

Optic nerve edema, also known as papilledema, can indeed lead to various visual disturbances. The swelling of the optic nerve can disrupt the normal transmission of visual signals from the eye to the brain, potentially resulting in symptoms such as blurred vision, visual field defects, and even the irregular movements you are describing. The irregular movement of the visual field could be attributed to the way the brain processes visual information when there is a disruption in the optic nerve's function. This could manifest as a sensation of the visual field moving or fluctuating, which may be particularly pronounced in peripheral vision.

The fact that your OCT and visual field tests did not reveal any significant retinal or macular changes is a positive sign, suggesting that the primary issue may lie with the optic nerve rather than the retina itself. However, the presence of shadows in the MRI scan near the left eye and nasal area raises some concerns. While these shadows may not indicate a significant brain lesion, they could represent other conditions such as sinus issues or vascular anomalies that might indirectly affect the optic nerve.

In terms of treatment, addressing the underlying cause of the optic nerve edema is essential. This may involve further investigation to rule out conditions such as increased intracranial pressure, inflammatory diseases, or other systemic issues that could contribute to optic nerve swelling. Depending on the findings, treatment options may include corticosteroids to reduce inflammation, managing any underlying conditions, or monitoring the situation closely if the edema is mild and not causing significant visual impairment.

It's also important to maintain regular follow-ups with your ophthalmologist and neurologist, as they can provide ongoing assessments of your condition and adjust treatment plans as necessary. If your symptoms worsen or new symptoms arise, such as severe headaches, nausea, or changes in consciousness, it is crucial to seek immediate medical attention.

In summary, optic nerve edema can indeed cause the irregular peripheral vision movements you are experiencing. Continuous monitoring and a thorough investigation of potential underlying causes are essential for effective management. Your healthcare providers will be your best resource in navigating this condition and ensuring that you receive the appropriate care.
