What is hypotony of the eye?
Hypotony is usually defined as an intraocular pressure (IOP) of 5 mm Hg or less. Low IOP can adversely impact the eye in many ways, including corneal decompensation, accelerated cataract formation, maculopathy, and discomfort. Clinically significant changes occur more frequently as the IOP approaches 0 mm Hg.
What is postoperative hypotony?
Postoperative hypotony mechanisms (Hyposecretion of aqueous from iridocyclitis may be clinically diagnosed by noting stagnant or slowly moving cells in the anterior chamber after residual viscoelastic has been ruled out.)
What is the ICD 10 code for maculopathy?
Toxic maculopathy, unspecified eye H35. 389 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM H35. 389 became effective on October 1, 2021.
Why does retinal detachment cause hypotony?
Subretinal fluid absorption facilitated by the retinal pigment epithelial pump will result in severe hypotony in retinal detachment during high myopia. In addition, fundus degeneration decreases the ability of choroidal blood vessels to counter the changes of IOP.
What is hypotony maculopathy?
Hypotony maculopathy is characterized by a low IOP associated with fundus abnormalities, including chorioretinal folds, optic nerve head edema in the acute setting , and vascular tortuosity.
What can cause hypotony?
Unilateral hypotony may be caused by the following:
- Wound leak.
- Overfiltering or inadvertent bleb.
- Ciliary body detachment – Serous, hemorrhagic, or tractional.
- Cyclodialysis cleft.
- Inflammation – Iridocyclitis or blunt trauma.
- Retinal detachment or retinotomy.
- Ocular ischemia.

How do you manage Hypotony?
One of the most effective surgical ways to manage an overfiltering bleb is to use compression sutures. In fact, compression sutures are an excellent option whether your bleb is overfiltering or has a leak. Compression sutures tamponade the tissue in order to prevent fluid from moving past the suture.
