When is screening recommended?
Cataract screening may be appropriate if:
- You are experiencing gradual changes in vision
- You notice increased glare or difficulty with night driving
- Your vision is not improving with updated glasses
- You have risk factors such as diabetes
- You are over the age where age-related changes are more likely
Even in the absence of symptoms, routine eye examinations can help detect early changes.
What happens during screening?
Screening is straightforward and typically includes:
- Visual acuity testing to assess clarity of vision
- Slit-lamp examination to examine the lens in detail
- Assessment of glare and visual function
- Evaluation of the retina, if necessary
These steps allow for a clear understanding of whether cataracts are present and how they are affecting vision.
This narrative provides an overview of what to expect during an eye exam.Why screening is important
Because cataracts develop gradually, changes may not be immediately noticeable.
Screening helps:
- Identify early changes before they become significant
- Monitor progression over time
- Ensure that other eye conditions are not missed
This is particularly important in patients with underlying health conditions or more complex visual symptoms.
Who performs cataract screening?
Screening may be performed by:
- Optometrists during routine eye examinations
- Ophthalmologists as part of a specialist assessment
If cataracts are suspected, referral for specialist evaluation may be recommended.
