Eye test intervals
August 16, 2010 Leave a comment
The following notes are taken from the guidance; “Frequency of GOS Sight Tests” issued by the Department of Health in January 2002.
These guidelines identify categories of patients who are symptomless and simply wish to have a routine re-examination.
Minimum Intervals Between NHS Sight Tests
| Patient Category | Re-Examination Interval |
| Under 16 years, in the absence of any binocular vision anomaly | 1 year |
| Under 7 years with binocular vision anomaly or corrected refractive error | 6 months |
| 7 years and over and under 16 with binocular vision anomaly or rapidly progressing myopia | 6 months |
| 16 years and over and under 70 years | 2 years |
| 70 years and over | 1 year |
| 40 years and over with family history of glaucoma or with ocular hypertension and not in a monitoring scheme | 1 year |
| Diabetic patients | 1 year |
An optometrist or OMP may carry out a sight test at a shorter interval than those listed above, either at the practitioner’s initiative for a clinical reason, or because the patient presents him/herself to the practitioner with symptoms or concerns which might be related to an eye condition. In these circumstances if a NHS sight test is carried out at an interval shorter than one of those listed above, the practitioner must annotate the GOS 1 form with one of the
following codes:
| Patient Category | Code |
| The Patient is at risk of frequent changes of prescription for reasons not requiring medical referral or for reasons already known to a medical practitioner. | 1 |
| The Patient has pathology likely to worsen, for example age-related macular degeneration, cataract, corneal dystrophy, or congenital anomalies. | 2 |
| The Patient has presented with symptoms or concerns requiring ophthalmic investigation which: | |
|
Result in referral to a medical practitioner; or |
3.1 |
|
Result in the issue of a changed prescription; or |
3.2 |
|
Result in either no change or no referral (the patient’s record should indicate any symptoms shown to support this category of claim, if necessary). |
3.3 |
| The Patient: | |
|
Needs complex lenses |
4.1 |
|
Has corrected vision of less than 6/60 in one eye |
4.2 |
| The Patient: | |
|
Has presented for a sight test at the request of a medical practitioner |
5.1 |

5.2 |
|
Is identified in protocols as needing to be seen more frequently because of risk factors |
5.3 |
| Other unusual circumstances requiring clinical investigation. | 6 |
