How is Blurred Vision Diagnosed in Cancer Patients?
Diagnosing the cause of blurred vision in cancer patients involves a comprehensive approach. An ophthalmologist will typically conduct a thorough eye examination, including visual acuity tests, fundoscopy, and slit-lamp examination. Imaging studies such as MRI or CT scans can help identify any tumors or metastases affecting the visual pathways. Blood tests and lumbar puncture may also be necessary to diagnose paraneoplastic syndromes or other systemic causes.
