Purpose: To describe features of uveitis-glaucoma-hyphema (UGH) syndrome, using Anterior Segment-Optical Coherence Tomography (AS-OCT) and Ultrasound Biomicroscopy (UBM) and to evaluate the diagnostic role of AS-OCT as an imaging technique alternative to UBM.
Design: Retrospective case series.
Methods: Four eyes of 4 patients with UGH syndrome were analyzed. All patients reported previous uncomplicated cataract surgery with in-the-bag implantation of single-piece-intraocular lens (IOL). They underwent at presentation complete ophthalmological examination and imaging with slit-lamp anterior segment photographs, UBM and AS-OCT.
Results: Although AS-OCT did not allow to visualize the structures behind the iris, it displayed a contact between IOL (plate and/or haptics) and iris and IOL tilting in 3 out of 4 eyes. AS-OCT directly detected the cause of UGH syndrome in one eye, 2 eyes required some expedients to display the iris chafing, like scans in mydriasis and/or patient's gaze direction change. AS-OCT did not allow to appreciate the IOL-iris contact (showed by UBM technique) only in one eye, probably due to the change of patient position from supine to sitting, and consequent anteriorization of iris diaphragm. Furthermore AS-OCT showed fine details, as capsular bag collapse and indirect signs of haptic malposition in 3 out of 4 eyes.
Conclusion: AS-OCT is a non-invasive technique that allows to determine IOL position and IOL-uveal contact in selected cases of UGH syndrome. Considering AS-OCT and UBM advantages and limitations, AS-OCT should be used as first imaging modality when clinical diagnosis is uncertain. When UGH diagnosis cannot be verified using AS-OCT, UBM should be performed.

Optic capture of a three-piece lens in the absence of posterior capsule support is an effective strategy for stabilizing and sequestering the optic to reduce the risk of dislocation and UGH syndrome compared to sulcus placement. We present a novel technique that facilitates optic capture in the presence of a contracted, fibrotic rhexis opening, while minimizing stress on the zonules by using iris retractors to assist in stabilization and expansion of the rhexis, followed by direct injection of the optic of the lens behind the anterior capsule opening into an optic captured configuration.

Purpose: To present a case of delayed recurrent hyphema following toric ICL implantation.
Observations: This case reports a 24-year-old Asian female who presented with sudden decrease in vision in the right eye, accompanied by recurrent massive anterior chamber hemorrhage, six months after bilateral implantation of toric ICL with central holes for myopia correction. Despite initial conservative treatment with immobilization and intraocular pressure (IOP)-lowering medication at another hospital, the hyphema persisted.

Purpose: The Hydrus microstent was approved by the FDA in August 2018 for use with cataract surgery to reduce IOP in patients with mild to moderate primary open angle glaucoma (POAG). Pivotal clinical trials demonstrated its overall safety and efficacy in lowering IOP. However, malpositioning of the implant can result in uveitis-glaucoma-hyphema (UGH) syndrome necessitating device explantation.

Uveitis-glaucoma-hyphema (UGH) syndrome is a rare condition characterized by intraocular inflammation, elevated intraocular pressure, and recurrent hyphema. Although UGH syndrome is typically caused by chafing between an intraocular lens and the iris or ciliary body, microinvasive glaucoma devices are becoming increasingly recognized as potential causes of recurrent intraocular inflammation. Herein, we discuss a case of UGH syndrome due to the subtle malposition of a Hydrus microstent that ultimately required surgical removal to manage.
