Traumatic cataract presenting with unilateral nasal hemianopsia
Journal of Cataract and Refractive Surgery
|September 7, 1999
Summary
A traumatic accident caused a localized visual field deficit in one eye. Cataract surgery successfully restored the patient's vision, demonstrating cataracts can cause visual field defects.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
Background:
- Traumatic injuries can lead to ocular complications.
- Posterior subcapsular cataracts are a known cause of visual impairment.
Observation:
- A 56-year-old male presented with a 3-month history of nasal visual field defect in the left eye post-trauma.
- Ophthalmological examination revealed a posterior subcapsular cataract in the left eye.
- Neurological examination showed no deficits.
Findings:
- Humphrey 24-2 visual field testing confirmed a nasal hemianopsia in the left eye.
- Cataract extraction and intraocular lens implantation resolved the visual field defect.
- Post-operative visual fields returned to normal.
Implications:
- This case highlights that cataracts can manifest as localized visual field deficits.
- Prompt cataract surgery can effectively correct such vision impairments.
- Ophthalmologists should consider cataracts in the differential diagnosis of visual field defects, even after trauma.
