UPDATE 1-Valeant Pharmaceuticals to buy Eyetech

Feb 13 (Reuters) - Valeant Pharmaceuticals International Inc said it agreed to buy privately owned eye drug firm Eyetech Inc, to expand its ophthalmology business.

Financial details of the deal were not disclosed, but Valeant said it would include an upfront payment and potential future milestones.

The deal is expected to be "immediately accretive," Valeant said in a statement.

In February, Valeant bought Brazil's Probiotica Laboratorios Ltd for about $86 million, boosting the Canadian company's presence in the sports food supplement market.
