Visual evoked response in syphilitic optic atrophy. A case report.
Acta Ophthalmologica
|October 1, 1986
Summary
Neurosyphilis caused vision loss, including reduced visual acuity and color vision defects. Treatment halted further decline but did not fully restore sight, despite normal brainwave patterns.
Area of Science:
- Ophthalmology
- Neurology
- Infectious Diseases
Background:
- Neurosyphilis is a serious complication of syphilis infection affecting the nervous system.
- Ocular manifestations of neurosyphilis can lead to significant visual impairment.
Observation:
- A patient presented with sudden vision loss, specifically reduced visual acuity and impaired color vision.
- Clinical examination revealed bilateral optic atrophy and an acquired red-green color vision defect.
Findings:
- Serological tests in blood and cerebrospinal fluid (CSF), along with CSF analysis showing pleocytosis and elevated protein, confirmed syphilitic etiology.
- Treatment with penicillin and systemic steroids arrested the visual decline.
- While visual evoked response (VER) latencies and morphologies were normal, amplitudes were reduced, indicating residual optic nerve dysfunction.
Implications:
- Early diagnosis and treatment of neurosyphilis are crucial to prevent irreversible vision loss.
- This case highlights the importance of considering syphilis in patients with unexplained optic neuropathy and visual disturbances.
- Despite treatment, residual visual deficits may persist, emphasizing the need for long-term monitoring.
