Emergency management of acute congestive glaucoma using an anterior chamber microsyringe and needle

A microsyringe-needle assembly is described for use in aspiration and microinfusion procedures in the anterior chamber. Assets of a lancet pointed 30-gauge needle, surface anesthesia, and fine control of ocular pressure and aqueous humor volume are stressed. Use of the assembly for emergency treatment of acute congestive glaucoma, surgical paracentesis, aqueous sampling, and drug infusion are described. Drug volumes and concentrations must be maintained at levels which do not damage corneal endothelium.
