To re-describe a condition that has not been mentioned in the literature for more than four decades and to outline a new method of treatment of the pathology using an argon laser.Nine patients were identified over a 2 year period who fitted a clinical picture consistent with the features of lymphangiectasia haemorrhagica. Three were treated for frequent recurrent haemorrhages with a newly developed technique using the argon laser and followed for up to 2 years.None of the three treated patients has had a recurrence of the condition to date. In the six untreated patients the condition resolved spontaneously after repeated attacks over between 8 months and 8 years.Lymphangiectasia haemorrhagica conjunctivae is probably more common than expected and may resolve spontaneously, but is readily amenable to treatment with the argon laser if attacks become frequent, uncomfortable or unsightly.
