Abstract
BackgroundTo describe the dissection and removal of the anterior hyaloid membrane using the conventional surgical microscope.Case presentationThis microscopic surgical approach involves dissecting the anterior hyaloid at the natural anatomical plane. A 30-gauge needle mounted on a 3.0 cc syringe is used to inject filtered air anterior to the anterior hyaloid membrane. Two patients needed this procedure; the first patient was pseudophakic with proliferative diabetic retinopathy, tractional retinal detachment, and vitreous hemorrhage. The second patient was phakic with proliferative diabetic retinopathy, anterior proliferative vitreoretinopathy, and recurrent vitreous hemorrhage. Both patients tolerated the procedure well with no complications.ConclusionPneumatic dissection of the anterior hyaloid membrane is previously thought to be only possible with the aid of ophthalmic endoscopy. This novel surgical approach provides surgeons with the option to perform pneumatic dissection of the anterior hyaloid when ophthalmic endoscopy is not available. Prospective studies are needed to reveal possible additional benefits or risks associated with this approach.

The anterior hyaloid membrane (AHM) becomes relevant in complex retinal detachments associated with proliferative vitreoretinopathy (PVR), where the AHM may provide a scaffold for cells to proliferate and for anterior PVR to form [3, 4]
