The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Trabeculotomy ab interno for open angle glaucoma.
Primary open-angle glaucoma is a condition associated with a long-term increase of pressure within the eye. It may gradually lead to permanent loss of sight because of damage to the nerve that connects the eye to the brain (optic nerve).
This procedure uses a specifically designed surgical instrument to remove a portion of tissue with the aim of improving the eye’s drainage pathway, leading to a reduction in pressure within the eye.
In addition ICD-10 code H40.1 Primary open-angle glaucoma is assigned.
The NHS Classifications Service has advised NICE that currently these are the most suitable OPCS-4 codes to describe this procedure. The OPCS-4 classification is designed to categorise procedures for analysis and it is not always possible to identify a procedure uniquely.
