“…It is easy to misdiagnose annular peripheral choroidal detachment as aqueous misdirection if the choroidal detachment is not detected. The important point is that annular peripheral choroidal detachment can be identified with standard echography, with a transverse approach as a smooth, or scallop-shaped thick membrane in the periphery with little aftermovement [8, 13]. Ultrasound biomicroscopy (UBM) is helpful to illustrate the anatomical changes associated with annular peripheral choroidal detachment.…”

We report a challenging case of recurrent flat anterior chamber without hypotony after trabeculectomy in a 54-year-old Black male with a remote history of steroid-treated polymyositis, cataract surgery, and uncontrolled open angle glaucoma. The patient presented with a flat chamber on postoperative day 11, but had a normal fundus exam and intraocular pressure (IOP). Flat chamber persisted despite treatment with cycloplegics, steroids, and a Healon injection into the anterior chamber. A transverse B-scan of the peripheral fundus revealed a shallow annular peripheral choroidal detachment. The suprachoroidal fluid was drained. The patient presented 3 days later with a recurrent flat chamber and an annular peripheral choroidal effusion. The fluid was removed and reinforcement of the scleral flap was performed with the resolution of the flat anterior chamber. A large corneal epithelial defect developed after the second drainage. The oral prednisone was tapered quickly and the topical steroid was decreased. One week later, his vision decreased to count fingers with severe corneal stromal edema and Descemet's membrane folds that improved to 20/50 within 24 h of resumption of the oral steroid and frequent topical steroid. The patient's visual acuity improved to 20/20 following a slow withdrawal of the oral and topical steroid. Eight months after surgery, the IOP was 15 mm Hg without glaucoma medication. The detection of a shallow anterior choroidal detachment by transverse B-scan is critical to making the correct diagnosis. Severe cornea edema can occur if the steroid is withdrawn too quickly. Thus, steroids should be tapered cautiously in steroid-dependent patients.

“…This second mechanism was highlighted by Trope and coworkers 30 who found ciliary effusions in two cases of confirmed malignant glaucoma, and by other observations in which annular effusions coexisted with moderately elevated IOP 27 and a high prevalence of minimal choroidal effusions and forward rotation of the ciliary body in the early postoperative period. 25,29 It is easy to presume that, once malignant glaucoma is established, elevated IOP causes the disappearance of the triggering effusion. The typical UBM image in established malignant glaucoma is a flat anterior chamber with flattened and rotated ciliary processes (Fig.17).…”

“…17 Of the published literature on UBM and glaucoma filtering surgery, a group of papers deal with non-penetrating surgery, [17][18][19][20][21] other with trabeculectomy, 23,24 and another one with the followup of glaucoma surgery complications. [25][26][27][28][29][30] The purpose of this communication is to provide some comments highlighting the utility of UBM in different aspects of glaucoma filtering surgery and, to a certain extent, to let images speak for themselves.…”
