Abstract
Trabeculectomy still remains the standard procedure of choice for a patient with uncontrolled glaucoma on maximum tolerated medical therapy and/or after laser. Although it has a high success rate of its own, a small number of patients continue to have a failing or a failed bleb despite a good bleb management. Needling had been a well-known modality of bleb management described in literature which has refined itself through years. However, in most of the situations, this modality of treatment is least considered. In this review, we will go through the evolution of needling procedure and various related options, their success rates, complications and emerging trends.
