A fitness to practise inquiry has found a GP in Longford guilty on one count of poor professional performance and one count of professional misconduct.
A decision on any sanction that might be imposed will be made at a later date by the full Medical Council.
Dr Syed Ali faced allegations that he changed a patient's medical records, without marking it as being retrospective.
It was alleged that he made the change after a Freedom of Information request in August 2013 for a patient's records, following a consultation on 4 February 2013.
The patient, Ms K, had attended the GP for an eye condition at Longford Medical Centre, Dublin Road, Longford and was prescribed medication.
She later attended the centre on two further occasions and was seen by two different locums.
Patient K later attended the Royal Victoria Eye and Ear Hospital in Dublin and was admitted as a medical emergency, with acute angle closure glaucoma in the left eye.
At the Medical Council inquiry, Dr Syed admitted the facts of the two allegations.
He accepted that adding an additional record, without marking it as retrospective, was poor professional performance.
He also accepted that making the change to make the record seem contemporaneous was professional misconduct.
He apologised to Patient K for any distress caused.
He said he made the addition to make sure the record was complete and reflected the consultation.
Among the additional information added to the record was that both eyes were quite inflamed, but vision was perfect.
It said he had advised that if the patient was not better in 24 hours, she was to return immediately for possible referral to the Eye and Ear Hospital.
Dr Syed qualified in Pakistan in 1982 and has worked as a GP in Ireland since April 1993.
