Summary
This summary is machine-generated.

Pseudophakia, or artificial lens implants, can cause erythropsia (reddish vision distortion) after sun exposure. This temporary condition is usually benign but may warrant ultraviolet protection.

Area of Science:

  • Ophthalmology
  • Vision Science

Background:

  • Erythropsia is an acquired color vision anomaly causing a temporary reddish hue in vision.
  • Various drugs and medical conditions are linked to erythropsia.
  • Pseudophakia is identified as a potential predisposing factor for erythropsia.

Observation:

  • Two adult males with pseudophakia (presence of artificial intraocular lenses) presented with transient erythropsia after outdoor exposure.
  • One patient had a monocular posterior chamber intraocular lens; the other had bilateral anterior chamber implants.
  • The intraocular lenses in both cases did not absorb ultraviolet (UV) light.

Findings:

  • Both patients were diagnosed with pseudophakic erythropsia.
  • Symptoms resolved with routine monitoring, and no recurrences were noted.

  • The condition, though generally benign, can be visually disconcerting.

    • Implications:

    • The exact mechanism of pseudophakic erythropsia is unknown.
    • A documented association exists between erythropsia and high levels of UV light exposure.
    • Recommending additional UV protection may alleviate patient concerns and prevent recurrence.
