Apr 24, 2017 · Hypotony can occur early (within two weeks of surgery), or late (after two weeks). In one study, late hypotony after primary trabeculectomy with mitomycin C and laser suture lysis occurred in 42.2% of eyes after two years of follow up.[3] Risk factors associated with hypotony include younger age, male gender, myopia, and systemic illness.[3]

Hypotony is defined as an intraocular pressure low enough to result in decreased vision; mechanisms include corneal edema, cystoid macular edema, maculopathy, choroidal folds and optic disc edema. Risk factors for hypotony maculopathy include male gender, young age, myopia, and glaucoma filtering surgery.

74-year-old female with a history of pseudophakia OU and primary open angle glaucoma OU that was treated in the past with trabeculectomy surgery OU (right eye 5 months prior, uncomplicated). The patient presented with acute onset decreased vision in the right eye. She denied any recent falls or trauma. She did not experience any pain or irritation.

Choroidal folds may be present in hypotony, external globe compression, ocular or orbital inflammation, tumors, neovascular membranes, and papilledema. In this case, choroidal folds occurred secondary to external globe compression by air extending inferiorly into the orbit from the frontal sinus.

Sep 27, 2017 · At 12 months, the mean number of glaucoma medications decreased from baseline of 3.5 ± 1.0 to 1.7 ± 1.5. Most common adverse events included hypotony (IOP . 6 mmHg), BCVA loss ≥ 2 lines (n = 4 at 12 months), and an IOP increase > 10 mmHg from baseline. The reported cases of hypotony were transient and …

Aug 9, 2016 · This video demonstrates the use of trans-conjunctival 10-0 nylon flap sutures in a patient referred with hypotony and choroidal detachments in the setting of an over-filtering bleb. This technique does not require taking down the conjunctiva, and the pressure can be titrated post-operatively through selective laser suture lysis in clinic.
