An investigation into Archie Harris's treatment revealed that a nurse had wrongly administered glue to a head wound sustained after he fell over at nursery on June 16.

The toddler should have been laying down with a protective gauze over his eye while being held by an assistant.

But instead the 14-month-old was sitting up, allowing the glue to drip down into his eye and sealing it shut for four days.

The Portsmouth City Primary Care Trust said the nurse had been spoken to about the incident at the walk-in treatment centre at St Mary's Hospital, Milton, Portsmouth, but had not been disciplined.

But dad Scott Harris, of Guildford Road, Fratton, said it was not good enough.

He said he had heard of other similar incidents at the centre, which is run by private company Care UK.

'If this was the first time that this had happened at St Mary's Treatment Centre then you could almost put it down to bad luck,' he said.

'However, I know that this has happened before.

'How many more children is this going to happen to before they learn from their mistakes?'

Archie appears to have recovered but his family are still taking him for check-ups on his eye.

The investigation said the nurse explained the procedure to Archie's mother but 'cannot recall' warning her that the child might move or that the glue might sting. Archie rubbed his head before the glue had dried, spreading it to his eyelid and lashes, the report said.

Innes Richens, the PCT's director of strategy and system management, said: 'We would like to say again how sorry we are about what happened to Archie and the distress that this caused him and his parents.

'It was a very unfortunate incident.

'Tissue glue is efficient and reliable in the management of superficial wounds in adults and children and is accepted practice in emergency departments nationwide.

'We share the centre's management view that the existing procedures are sound.

'Centre managers have spoken to the nurse and taken appropriate measures, which are not disciplinary.'
