14. Visual field test: It checks the patient’s peripheral vision.
15. Fundoscopy: The doctor examines the retina and optic nerve.
16. Electroretinography (ERG): This measures the electrical response of the retina to light.
17. Evoked potentials: These tests assess the brain’s response to visual stimuli.
18. Genetic testing: If congenital factors are suspected, genetic testing may be done.
19. Blood glucose test: To rule out diabetes as a cause.
20. Infection screening: Blood tests and cultures can identify infections affecting the nervous system.
