Abstract/OtherAbstract:
Hypotony maculopathy, first described in 1954 by Dellaporta, usually occurs after antiglaucomatous surgery or after perforating eye injuries; it is characterized by hypotony associated with fundus abnormalities, including papilloedema, vascular tortuosity and chorioretinal folds. In hypotony maculopathy, the scleral wall collapses inward, resulting in redundancy of the choroid and retina, leading to chorioretinal wrinkling. As the antero-posterior diameter of the vitreous cavity decreases, the very thick perivofeal retina surrounding the very thin foveal retina is thrown into radial folds around the fovea. It has been reported that hypotony maculopathy occurs in up to 20% of cases of glaucoma filtering surgery and has become more common after the introduction of antimetabolites. Young age, myopia, primary filtering surgery, systemic illnesses and elevated preoperative intraocular pressure (IOP) have been found to be associated with hypotony maculopathy. Hypotony maculopathy is treated with procedures designed to elevate IOP, which may reverse the inward scleral bowing and improve visual acuity. The successful treatment of hypotony maculopathy depends on the correct identification of its cause. Once the cause is detected, treatment should be employed as soon as possible because delayed normalization of the IOP may result in permanent macular chorioretinal changes and poor vision. This review will explore the definition, mechanisms, clinical findings and treatment of hypotony maculopathy.
