Choroidal Detachment, Flat Anterior Chamber, and Hypotony as Complications of Neodymium:YAG Laser Cyclophotocoaguiation

Severe hypotony, flat anterior chamber, and serous choroidal detachment after transscleral neodymium: YAG laser cyclophotocoagulation (Nd:YAG-CPC) for three cases of intractable glaucoma are reported. The three patients had failed previous filtering surgery and were receiving maximal medical therapy. The types of glaucomas treated were two cases of primary open-angle and one chronic-angle closure. The complications were noted between 1 and 2 weeks from the time of treatment. One patient improved spontaneously after 1 week of observation. Another patient required drainage of the choroidal effusion and anterior chamber reformation. The last patient remains under observation with a low intraocular pressure (IOP) and a slowly resolving serous choroidal detachment. Though the incidence of shallow anterior chambers is three cases (0.5%) in this series of 750 Nd:YAG-CPCs, it represents a serious problem that had not been reported previously.

Medial rectus muscle injuries associated with functional endoscopic sinus surgery: Characterization and management

Objective To characterize and evaluate treatment options for medial rectus muscle (MR) injury associated with functional endoscopic sinus surgery (FESS). Design Retrospective interventional case series Participants A total of 30 cases were gathered from 10 centers. Methods Cases of orbital MR injury associated with FESS surgery were solicited from members of the American Society of Ophthalmic Plastic & Reconstructive Surgery (ASOPRS) through an e-mail discussion group. Main Outcome Measures Variables assessed included patient demographics, computerized tomography and operative findings, extent of MR injury and entrapment, secondary orbital/ocular injuries, initial and final ocular alignment and ductions, and interventions. Results A spectrum of MR injury ranging from simple contusion to complete MR transection, with and without entrapment, was observed. Four general patterns of presentation and corresponding injury were categorized. Conclusions Medial rectus muscle injury as a complication of FESS can vary markedly. Proper characterization and treatment are important, particularly with reference to the degree of direct MR injury (muscle tissue loss) and entrapment. Patients with severe MR disruption can benefit from intervention but continue to show persistent limitation of ocular motility and functional impairment. Prevention and early recognition and treatment of these injuries are emphasized.

Angle-closure glaucoma in association with orbital pseudotumor

PURPOSE To describe the pathophysiology of angle-closure glaucoma secondary to idiopathic inflammatory orbital pseudotumor. DESIGN Retrospective, small noncomparative case series. PARTICIPANTS Three patients with angle-closure glaucoma and orbital pseudotumor. METHODS The pathophysiology of this entity was investigated using magnetic resonant imaging (MRI) and ultrasound biomicroscopy (UBM). MAIN OUTCOMES MEASURES Clinical features, anterior chamber angle configuration, and intraocular pressure. RESULTS Angle closure from anterior rotation of the ciliary body caused by choroidal effusions secondary to pseudotumor was demonstrated using MRI and UBM. Two of the three cases resolved after treatment for orbital pseudotumor. CONCLUSIONS Idiopathic orbital pseudotumor is a cause of secondary angle-closure glaucoma. The mechanism of angle closure is anterior rotation of the ciliary body secondary to choroidal effusions resulting from the orbital inflammation.

Transorbital craniotomy through a suprabrow approach: A case series.

Six cases of posterior orbital mass lesions are described in which a suprabrow approach was utilized for transorbital craniotomy. This technique offers several advantages over traditional supraorbital and transcranial approaches to deep orbital tumors. The results were anatomically and cosmetically excellent in all cases. The surgical technique for transorbital craniotomy, along with its advantages and potential complications, are explained in detail. The clinical presentation, radiological features of the lesions, postoperative outcome, and complications are discussed.
