Three cases of local extraocular extension of retinoblastoma following intraocular surgery via a transscleral approach have been seen in one centre during a 12-month period. This number represents a significant increase on the previous incidence of this serious complication, which may be related to more widespread use of vitrectomy techniques. Orbital and local lymph node recurrence of retinobl...

BACKGROUND Macular edema is a common complication of uveitis and represents a therapeutic challenge, especially in children. Recently, intravitreal dexamethasone implants have been shown to decrease intraocular inflammation and to control uveitic macular edema in patients with non-infectious intermediate or posterior uveitis. FINDINGS An 11-year-old boy with bilateral granulomatous idiopathic...

Purpose To demonstrate an unusual case of orbital trauma due to dental surgery complication. Observations An elderly patient who underwent dental implantation to the zygomatic bone was hospitalized in the ophthalmology department with impaired abduction of her right eye, also evident on ocular examination. Head computed tomography demonstrated damage to the lateral rectus and to the inferior ...

BACKGROUND In addition to functional goals, a satisfactory aesthetic outcome is important for reconstruction of fronto-orbital osseous defects. The purpose of this study is to report on a method for presurgical fabrication of custom implants using 3-dimensional (3-D) imaging data and computer-assisted manufacturing techniques. METHODS Preoperative 3-D computed tomography data were processed a...

A case of acquired Brown syndrome caused by surgical repair of medial orbital wall fracture is reported in the present paper. A 23-year-old man presented at the hospital with right periorbital trauma. Although the patient did not complain of any diplopia, the imaging study revealed a blow-out fracture of the medial orbital wall. Surgical repair with a calvarial bone autograft was performed at t...

BACKGROUND Ocular motility impairment associated with orbital trauma may have several causes and manifest with various clinical symptoms. In some cases orbital reconstructive surgery can be very challenging and the results are often unsatisfactory. The use of modern imaging techniques aids proper diagnosis and surgical planning. CASE REPORT The authors present the case of a 29-year-old male w...

Silent sinus syndrome (SSS) or chronic maxillary atelectasis (CMA) is characterized by enophthalmos or hypo Globus along with maxillary sinus atelectasis and lateralization of the uncinate process without classic rhino sinusitis symptoms. A previous description of surgical management includes maxillary antrostomy with orbital floor repair via an implant, possibly as a two-stage procedure. The o...

OBJECTIVE To evaluate the use of computer-assisted designed and manufactured (CAD/CAM) orbital wall and floor implants for late reconstruction of extensive orbital fractures. METHODS We performed a retrospective data review on 29 patients treated for extensive orbital fractures from January 1, 1997, through December 31, 2007, at the University College London Hospitals. The use of a CAD/CAM te...

IMPORTANCE Numerous techniques have been described to repair nasal septal perforations (SPs). However, many are technically challenging, with varying degrees of success. OBJECTIVE To evaluate the use of polyethylene (Medpor; Porex Technologies) implants in the closure of nasal SPs. DESIGN AND SETTING Prospective cohort study in an academic research setting. PARTICIPANTS Fourteen patients ...
