Flashes and Floaters

Common visual symptoms that may indicate serious retinal conditions

What are Flashes and Floaters?

Floaters are mobile shadows cast by debris in the vitreous gel, while flashes are light streaks caused by mechanical stimulation of the retina during posterior vitreous detachment. Most are benign age-related changes, but sudden onset requires immediate evaluation.

Understanding the Disease

Risk Factors

  • • Age over 60 (most common)
  • • Myopia (nearsightedness)
  • • Recent eye surgery (cataract)
  • • Previous eye trauma
  • • Inflammation inside the eye
  • • Family history of retinal problems

Symptoms

⚠️ SEEK IMMEDIATE CARE for sudden onset symptoms

Floaters:

  • • Intermittent flashing lights
  • • New floaters (mobile shadows)
  • • Black dots or cobweb appearance

Flashes:

  • • Brief streaks of light
  • • Usually in peripheral vision
  • • Often with eye movement

Diagnostic Methods

Dilated Eye Examination

Complete retinal evaluation

Indirect Ophthalmoscopy

Detailed peripheral retinal examination

Treatment Options

Observation (Most Cases)

Usually no treatment needed for uncomplicated cases

Regular monitoring and patient education about warning signs

Vitrectomy (Rare)

Only for severe cases significantly impacting quality of life

Reserved for exceptional circumstances due to surgical risks

Prevention & Management

  • • Regular eye examinations
  • • Immediate evaluation of sudden symptoms
  • • Education about warning signs
  • • Protection from eye trauma
  • • Prompt treatment of eye inflammation
  • • Follow-up care as recommended

Excellent Prognosis

85% of patients never develop complications from flashes and floaters. Symptoms typically improve within 3 months as the brain adapts. The key is proper evaluation to rule out serious retinal conditions and appropriate follow-up care.

When to Seek Immediate Care

Call immediately if you experience sudden shower of floaters, frequent flashing lights, or any curtain or shadow in your vision. These may indicate retinal tear or detachment requiring emergency treatment.
