Treatment of hyperfiltering blebs with Nd : YAG laser-induced subconjunctival bleeding

Purpose: To assess the feasibility of a new technique to manage hyperfilter ing blebs after penetrating glaucoma surgery. Methods: Neodymium:yttrium-aluminum-garnet (Nd:YAG) laser bursts were used to induce bleeding in conjunctival and episcleral vessels in the bleb area to achieve local delivery of autologous blood, Results; In the three cases reported here in which this technique was used, the treatment was successful and safe, leading to resolution of hypotony a nd reduction of the bleb with no complications. Conclusion: Subconjunctival bleeding can be achieved using Nd:YAG laser, an d can represent a valuable alternative to autologous blood injection in cas es of hyperfiltration after glaucoma surgery.
