A prospective observational case-series study was conducted in a single tertiary university-affiliated medical center. The study was approved by the local Institutional Ethics Committee of the Rabin Medical Center, Petach-Tiqva, and adhered to the tenets of the Declaration of Helsinki. Written informed consent was obtained from all participants.

The study included patients over the age of 18 years who underwent glaucoma surgery and were subsequently diagnosed with choroidal detachment. Choroidal detachment was defined as an elevation of the retina and choroid on both fundoscopic and B-scan ultrasound examinations. The presence and extent of ciliary body detachment was assessed by ultrasound biomicroscopy (UBM) using both probes of the Eye Cubed Ophthalmic Ultrasound System (Ellex/Innovative Imaging, Inc, Adelaide, Australia).

Excluded from the study were patients who were unable to undergo intraocular pressure (IOP) measurements or ophthalmic or UBM examinations, in addition to patients who were diagnosed with choroidal detachment prior to glaucoma surgery or had a history of intraocular surgery other than uncomplicated phacoemulsification or in whom the choroidal detachment had other possible causes such as ocular malignancy, ocular trauma, or intraocular inflammation.

Follow-up examinations were scheduled on 1 day, 1 week, and 1, 3 and 6 months after surgery. Patients with persistent detachments were followed until complete resolution.

Data were collected for each patient as follows: age and gender, systemic medical history, ocular history, glaucoma type, ocular medications, preoperative IOP, visual acuity, and type of glaucoma surgery. Each visit included an assessment of best corrected visual acuity (BCVA), measurement of IOP with a Goldmann applanation tonometer, comprehensive slit-lamp examination, and UBM examination performed by one of two UBM specialists (O.G.O. and D.B.(. The specialists evaluated the choroidal detachment with particular attention to its location, extent, and height, and presence of concurrent ciliary body detachment. The timing relative to glaucoma surgery on which choroidal detachment was diagnosed, its clinical and ultrasonic appearance, and its clinical course, management, and outcomes were assessed.

Postsurgical treatment was administered at the discretion of the surgeon and tailored to the patient. It generally included topical cycloplegic agents, antibiotic drops, as well as topical and/or oral steroids. The duration of treatment varied according to the clinical course.
