Bleb Revision Techniques for Hypotony Maculopathy: A Review

Hypotony maculopathy, characterized by chorioretinal folds with potential for vision loss, can occur as a complication from overfiltration following trabeculectomy. Its rate has increased in the era of antifibrotics. The challenge in treatment involves raising intraocular pressure to treat hypotony maculopathy while maintaining a level low enough to control glaucoma progression. This review aims to cover the expanse of nonsurgical and surgical management options available. Since a gold standard for hypotony maculopathy treatment is not established, selecting and tailoring treatment options will depend on specific patient and bleb characteristics.
