There has been no review of the number of orbital decompressions performed in England over a given time period.

All consultant episodes and hospital admissions in England over a period of 10 years from 2005 to 2015 was performed looking into the number of orbital decompressions performed, the proportions of male and female patients that had the procedure, the number of cases that were performed as an emergency, the number of day case procedures and the mean length of stay. Data was collected from the Health and Social Care Information Centre covering all NHS Hospitals in England including acute hospitals, primary care trusts and mental health trusts in an anonymized format.

Over the 10 year period from 2005 to 2015 there were a total of 3659 consultant episodes where orbital decompression was the primary procedure performed. 72 percent were female and the average patient age was 49 years and this remained unchanged over the 10 year period. 6 percent of all cases were performed as emergencies. The mean length of stay was 1.8 days. 6 percent were performed as day cases with a trend towards an increasing proportion of day cases over the 10 year period. This data provides an interesting insight into the incidence of orbital decompression in the Nation Health Service of England.

The 10 year analysis shows no change in the proportion of females having orbital decompression nor in the mean age at which the procedure is performed. There has been an increase in orbital decompressions from 5.8 to 6.1 per million per population per year. Despite the increase in available treatments for thyroid orbitopathy there has been an increase in orbital decompression and no change in the proportion of emergency decompressions.
