Washed-out vision is similar to faded sight, with poor contrast and pale colours. It frequently reflects diffuse retinal or optic nerve dysfunction.
Underlying Conditions
Optic neuropathies, macular oedema, widespread retinal ischaemia, and advanced glaucoma can all lower contrast sensitivity. Early cataract, severe anaemia, and systemic hypotension may also contribute.
- Patients may struggle to distinguish shades or read low-contrast print
- Testing may show relatively good acuity but poor contrast sensitivity
- Field defects and colour vision loss often accompany nerve disease
- Systemic vascular and inflammatory conditions are important contributors
Management
Treatment targets the specific cause, from controlling inflammation or vascular risk to surgery for cataract. Visual aids that enhance contrast and lighting are helpful.
- Urgent evaluation is needed when washed-out vision appears suddenly
- Regular monitoring detects progression or treatment response
- Rehabilitation specialists can suggest filters and aids to maximise function
- Systemic work-up may uncover previously undiagnosed disease
