Data notes
Overview
- Summary of dataset and variables
This dataset shows the number of low vision assessments by the visual acuity recorded.
Wales General Ophthalmic Services (WGOS) 3 enables patients who would benefit from optical and non-optical aids as well as holistic rehabilitation support (including sight impairment registration) and advice to access a low vision service in or close to their place of residence.
The data is broken down by visual acuity recorded during the assessment and Local Health Board. Visual acuity measures the clarity or sharpness of a person’s vision—6/12 means seeing at 6 metres what a person with normal vision sees at 12 metres, while 6/60 indicates significantly poorer vision. The dataset provides an overview of low vision service activity and the distribution of visual acuity levels among patients across health boards.
- Data collection or calculation
Visual acuity is measured according to the "Snellen fraction" by comparing the distance in metres at which a patient can correctly identify a letter with the distance at which a person with standard vision could identify it. For example, 6/6 indicates normal vision, while 6/12 means the patient can see at 6 metres what a person with standard vision could see at 12 metres. To arrive at the overarching visual acuity categories presented in this data, various categories in the underlying data were combined, such as ‘6/7.5 – 6/12’ being combined with ‘6/6+’ to form the ‘6/12 or better category’. The number of low vision assessments with each visual acuity is then broken down by financial year and health board to arrive at the final dataset. The data is based on claims made by practices to NHS Wales Shared Services Partnership (NWSSP) for payment. Practices submit a record card to NWSSP and this data generates the payment from the system. NWSSP provide an aggregated dataset with counts to Welsh Government.
- Statistical quality
On 1 April 2019, health service responsibility for Bridgend residents moved from Abertawe Bro Morgannwg to Cwm Taf. Health board names also changed: Cwm Taf became Cwm Taf Morgannwg, and Abertawe Bro Morgannwg became Swansea Bay. See the weblinks section for official statements.
