A slit-lamp needling filtration procedure for uncontrolled glaucoma in pseudophakic and aphakic eyes

In one aphakic and one pseudophakic patient without previous filtration sur gery, a transconjunctival needling procedure similar to that used for faile d filtration procedures was performed to create a filtering bleb. In both c ases, intraocular pressure was successfully lowered for 6 months until the occurrence of bleb encapsulation, which was relieved by transconjunctival n eedling. There were no complications. In selected cases, this minimally inv asive slit-lamp needling procedure provides successful filtration.
