Lacrimal Gland Ductal Cyst Infection Presenting as Acute Orbital Cellulitis With Abscess.

ABSTRACT: Herein, the authors report a case of lacrimal gland ductal cyst infection presenting as acute orbital cellulitis with an abscess. A 45-year-old man without any history of trauma and a specific medical history presented with progressive painful periorbital swelling in the left eye and diplopia. At the first visit, the patient showed a best-corrected visual acuity of 0.2; erythematous swelling of the upper eyelid; superficial punctate keratitis, severe conjunctival chemosis in the left eye; and pus in the lateral canthal area. The patient had binocular diplopia and left eyeball movement limitation. Orbital computed tomography showed a peripherally enhanced periorbital soft tissue mass along the superotemporal aspect of the left globe, which was suggestive of an abscess. The authors diagnosed the patient with acute orbital cellulitis with an abscess. Intravenous antibiotics and steroids and topical antibiotics and steroids were administered. On the 4th day of the treatment, visual acuity and eyeball movement limitation had improved, and a small opening of the lacrimal gland duct was observed in the left upper conjunctival fornix. Methicillin-resistant Staphylococcus aureus was identified on culture. Finally, the patient was diagnosed with lacrimal gland ductal cyst infection presenting as acute orbital cellulitis. Lacrimal duct cyst infection should be considered as a cause of orbital cellulitis.

Transorbital Penetrating Intracranial Injury by a Battery.

The authors report a patient of transorbital penetrating intracranial injury by a battery. A 59-year-old man presented with a foreign body in the left orbital region after an explosion during waste combustion. Physical examination revealed his left eyelid had been punctured and the eyeball ruptured by what appeared to be a battery, which was lodged in the left orbit. The patient was neurologically intact. Facial computed tomography showed a ca. 6.2 × 1.7 cm sized metallic foreign body, probably an electric battery, penetrating through the left orbit and orbital roof and terminating in the left anterior cranial fossa. Clinical presentation, treatment course, and follow-up are discussed.

Retained Eyeglasses in the Orbital Cavity After Penetrating Facial Trauma.

This study describes a 68-year-old man who was presented to the emergency department with left orbital cavity penetration by his eyeglasses. The eyeglasses had entered the orbit and at presentation his eyesight could not be measured. The foreign body was extracted carefully and panfacial bone fractures were then reduced through lateral rhinotomy combined with a lip-splitting incision. When planning removal of an unusual foreign body from the orbital cavity, care should be taken not to injure the optic nerve, periorbital musculatures, or the eyeball.

Rhabdomyolysis Presenting as Orbital Apex Syndrome.

Rhabdomyolysis is a condition in which striated muscle tissue breaks down rapidly and releases muscular cell constituents into extracellular fluid and the circulation. Renal symptoms, such as acute renal failure, are major complications of rhabdomyolysis. However, no previous report of rhabdomyolysis associated with orbital complication has been issued. Here, we report the first patient of rhabdomyolysis presenting as orbital apex syndrome. A 66-year-old man presented with right periorbital swelling with erythematous patches and conjunctival chemosis. In addition, swelling, redness, and vesicles were observed in both lower legs. He was found in a drunken state with the right side of his face pressed against a table. Ophthalmic examination showed right eye fixation in all directions and ischemic change of retina. Blood testing showed elevated muscle enzyme associated with muscle destruction. And computed tomography of the orbit showed swelling of right extraocular muscles and crowding of right orbital apex. Under a diagnosis of rhabdomyolysis-associated orbital apex syndrome and central retinal artery occlusion, intravenous steroid and antibiotics therapy with intraocular pressure-lowering topicals were begun. Clinical presentation, treatment course, and follow-up are discussed.

Acquired Brown Syndrome Treated With Traction of Superior Oblique Tendon.

Brown syndrome is a rare strabismic disease characterized by a limited elevation in adduction of the eye. The lengthening/weakening of superior oblique muscle is the main way of surgical intervention for this disease. A 7-year-old boy was diagnosed as having acquired Brown syndrome in his right eye after injury in his face. We experienced successful release of this Brown syndrome through mere pulling outward of superior oblique tendon during surgical exploration. We briefly discuss why this manipulation of superior oblique tendon that we performed was successful.

Temporal Artery Calciphylaxis Presenting as Temporal Arteritis in a Case of Rhinoorbitocerebral Mucormycosis.

Mucormycosis is a rare often fatal opportunistic fungal infection. It is typically described in patients with diabetes in ketoacidotic status and is rare in renal transplant recipients. Calciphylaxis is a rare and highly morbid disease of vascular calcification affecting patients with end-stage renal disease (ESRD). The first case of a renal transplant recipient who was inflicted with both rhinoorbitocerebral mucormycosis and calciphylaxis is reported. A 45-year-old man presented with 2-day history of left upper blepharoptosis, periorbital pain, left-sided headache, binocular diplopia, and left V2 numbness. He had undergone renal transplant for ESRD 7 months earlier with resultant immunosuppressive therapy. MRI and nasal biopsy confirmed rhinoorbitocerebral mucormycosis. Immunosuppressive therapy was stopped and antifungal therapy begun. He had orbital exenteration for progressive rhinoorbitocerebral mucormycosis. Two months later, the patient reported new-onset intermittent bitemporal headache and bilateral swollen, tender temporal arteries. Temporal artery biopsy revealed features consistent with calciphylaxis. Clinical presentation, treatment course, and follow up are discussed.

A clinical analysis of bilateral orbital fracture.

Although bilateral orbital fracture can cause serious eyeball and facial skeletal problems, few reports have been issued on the topic. We analyzed the clinical features of bilateral orbital fracture by reviewing the medical records of 147 patients and compared bilateral and unilateral fractures by reviewing the literature.Bilateral orbital fracture was most common in men aged between 50 and 59 years. A traffic accident was the leading cause of trauma, and average time between trauma and surgery was 12.2 days. Bilateral medial fracture accompanied by nasal fracture accounted for the overwhelming majority, and impure blowout fracture in at least 1 eye occurred in 69.4% of the 147 patients. Associated ocular injuries seemed to be similar for bilateral and unilateral fracture. Thirty-five patients (23.8%) had other multiple traumas affecting other than the eyes, and this significantly increased the need for surgery (P < 0.05). Of the 48 patients who underwent surgery, including 4 cases of bilateral surgery, 21 patients who had ocular motility restriction with central diplopia within 30 degrees almost completely recovered. No significant relation between the timing of surgery and improvement was found. Although unilateral surgery was performed in most cases, facial asymmetry related to enophthalmos was unclear at 6 months postoperatively.In summary, bilateral orbital fracture was found to be clinically distinguishable from unilateral fracture in several aspects. We hope these findings provide a reference guide to the approach and management of bilateral orbital fracture.

Iatrogenic cerebrospinal fluid oculorrhea.

Cerebrospinal fluid leakage into the orbit (CSF orbitorrhea) or through the orbit to the exterior (CSF oculorrhea) occurs when there is a communication between orbit and subarachnoid space. It has rarely been described. We report a case of CSF oculorrhea following surgery for recurrent sphenoid wing meningioma. A 67-year-old patient who underwent craniotomy for a recurrent sphenoid wing meningioma complained of tearing from the ipsilateral eye. Fluid collection was observed in the right periorbital area contiguous with craniotomy wound. With wide retraction of eyelids, a 1-cm longitudinal full-thickness laceration through the conjunctiva toward the lateral orbital rim was visualized in the area of the lateral canthal tendon. Steady leakage of pink-tinged serous fluid through the forniceal laceration was observed. With a presumed diagnosis of iatrogenic CSF oculorrhea, the patient was treated conservatively with resolution by postoperative day 6.

Metastatic renal cell carcinoma to the orbit and the ethmoid sinus.

The orbit is an unusual site for metastatic renal cell carcinoma (RCC), and concurrent metastases of RCC to the ethmoid sinus and the orbit occur very rarely. The treatment goal of orbital and paranasal metastatic RCC is total exenteration. We report a rare case of metastatic RCC to the orbit and the ethmoid sinus. The patient underwent total exenteration, craniotomy, and total maxillectomy. Six years after surgery, the patient showed no sign of metastasis and had successful cosmetic result by using orbital prosthesis.

Has decreased visual acuity associated with blunt trauma at the emergency department recovered?

PURPOSE: After blunt ocular trauma, many patients complain of visual disturbances at the emergency department of a hospital. The aim of this study was to investigate the clinical manifestations and related factors of refractive change after blunt ocular trauma. METHODS: This prospective study included 192 patients who had a history of monocular blunt trauma without any corneal or conjunctival open wound. None of them had a history of ocular disease or surgery. The examinations covered uncorrected visual acuity, best corrected visual acuity, intraocular pressure, refractive power, gonioscopy for anterior chamber angle, and A-scan ultrasonography for the measurement of axial length, anterior chamber depth, and the lens thickness. All the examinations were performed right after the trauma and then 1 week, 1 month, and 3 months later. The corneal topography was examined using an ORB scan right after the trauma and 1 month later. RESULTS: A myopic change of -2.01 ± 2.27 diopters (D) in the injured eyes, compared with the sound eyes, was identified in 161 patients (83.9%), which showed an aspect of recovery as time passed of -0.14 ± 0.51 D at 1 month after the trauma. The anterior chamber depth of the injured eyes, unlike that of the sound eyes, was significantly lower (P = 0.028), and the anteroposterior diameter of the lens of the injured eyes was significantly higher (P = 0.043). CONCLUSIONS: Blunt ocular trauma induced a significant myopic refractive change due to lens thickening and anterior chamber shallowing, which recovers spontaneously as time passes. Therefore, conservative management and examination of refractive change without artificial refractory correction would be a good choice for managing eyes with blunt trauma at an emergency department.

Clinical characteristics and treatment of blow-out fracture accompanied by canalicular laceration.

BACKGROUNDS: Blow-out fracture and canalicular laceration can occur simultaneously as a result of the same trauma. Despite its importance, little research has been conducted to identify clinical characteristics or surgical techniques for repair of a blow-out fracture accompanied by canalicular laceration. The aim of this study was to evaluate the clinical characteristics, the surgical approach, and the outcomes. METHODS: Thirty-four eyes of 34 patients who underwent simultaneous repair of canalicular laceration using silicone tube intubation and reconstruction of blow-out fracture were included. Medical records were retrospectively reviewed for patient demographics, nature of injury, affected canaliculus, location, and severity of blow-out fracture, associated facial bone fracture, ophthalmic diagnosis, length of follow-up period, and surgical outcome. RESULTS: Mean patient age was 40.0 years (range, 17-71 y). The mean follow-up was 7.3 months. Fist to the orbital area (10 patients, 29.4%) was the most common cause. There were 24 lower canalicular lacerations (70.6%), 6 upper canalicular lacerations (17.6%), and 4 upper and lower canalicular lacerations (11.8%). Isolated medial wall fractures were most common (area A4: 20/34, 58.8%). Fractures involving both the floor and medial wall and maxillo-ethmoidal strut (areas A1, A2, A3, and A4) were the second most common (6/34, 17.6%), and floor and medial wall with intact strut (areas A1, A2, and A4) were injured in 6 patients (17.6%). Pure inferior wall fractures were least frequent (areas A1 and A2: 2/34, 5.9%). The severity of the fracture was severe in most patients except for 1 linear fracture with tissue entrapment and 1 moderate medial wall fracture (32/34, 94.1%). There was lid laceration in 20 patients (58.8%). Nasal bone fracture (5/34, 14.7%) was the most common facial bone fracture. Tubes were removed at a mean of 3.3 months (range, 3-4 mo). In total, 31 patients (91.2%) achieved complete success in canalicular laceration and blow-out fracture repair. No significant complications were encountered. CONCLUSION: Fractures involving the medial wall with a lower canalicular laceration were the most common among concomitant blow-out fractures and canalicular lacerations. The severity of the fracture was most often classified as severe. Computed tomographic scan of the orbit and facial bones for identification of any additional injuries such as orbital wall and facial bone fractures should be performed in patients with canalicular laceration. To avoid disruption of the medial canthal area, repair of the canalicular laceration with silicone tube intubation was performed before reconstruction of the blow-out fracture through transconjunctival and transcaruncular approaches. Finally, the tube was fixed after blow-out fracture surgery, and these surgical orders yielded good surgical outcomes without complications.

Comparison of the outcomes of blowout fracture repair according to the orbital implant.

PURPOSE: The clinical outcomes of blowout fracture repair classified by 2 types of orbital implants (Macropore and Medpor) were compared. PROCEDURES: The medical records of 331 patients with orbital fractures that were treated surgically by 1 surgeon at Gachon University Gil hospital, from March 2007 to March 2009, were reviewed. Patients who had diplopia or limited extraocular motion, significant enophthalmos (>2 mm), or a large fracture on a computed tomographic scan (>50% of the floor area) were enrolled. The clinical outcomes were compared between patients who received surgical repair using Macropore and those who had surgical repair using Medpor. RESULTS: One hundred six patients had surgical repair using Macropore and 225 patients were surgically treated with Medpor. Both the Macropore (n = 106) and the Medpor groups (n = 225) showed significant clinical improvement. The degree of preoperative/postoperative diplopia and limited extraocular motion was not different between the 2 groups. In addition, there was no difference in the preoperative/postoperative enophthalmos between the 2 groups. CONCLUSIONS: Both Macropore and Medpor were associated with equally safe and satisfactory patient outcomes without notable complications.

Comparison of the outcomes of non-trapdoor-type blowout fracture repair according to the time of surgery.

PURPOSE: We classified the outcomes of non-trapdoor-type blowout fracture repair by surgical indications and then compared the outcomes according to the time of treatment. METHODS: The medical records of 591 patients with orbital fractures that were treated surgically within 30 days of trauma were included in the study. The enrolled patients were classified into 2 groups by the major surgical indications: 1 group included patients with diplopia or limited extraocular motion, and the other group of patients had significant enophthalmos (>2 mm) or a large fracture on computed tomography (>½). The clinical outcomes were compared between the patients who received surgical repair within 14 days of trauma (early) and those who received treatment from 15 to 30 days after the trauma (delayed) in each group. RESULTS: Two hundred thirty-three patients received surgical repair because of diplopia or limited extraocular motion. Both the early repaired group (n = 195) and the delayed repaired group (n = 38) showed significant improvement after surgeries. The degree of preoperative and postoperative diplopia and limited extraocular motion was not associated with differences between the 2 groups. Four hundred one patients received surgical repair because of enophthalmos (>2 mm) or a large fracture on computed tomography (>½). Both the early repaired group (n = 328) and the delayed repaired group (n = 73) showed significant improvement of the enophthalmos after surgeries. The degree of preoperative/postoperative enophthalmos did not show differences between the 2 groups. CONCLUSIONS: If the blowout fracture repairs were performed within a month, the surgical outcomes did not differ according to the time of surgery in the cases of nontrapdoor blowout fracture.

Endoscope-assisted repair of pediatric trapdoor fractures of the orbital floor: characterization and management.

BACKGROUND: The mechanism of injury, the clinical presentation, the natural history, and the indications for the treatment of orbital fractures in the pediatric population are less well described than they are in adults. The purpose of this study was to describe the specific characteristics and management of trapdoor fractures of the orbital floor in the pediatric population. METHODS: We enrolled 18 pediatric patients younger than 13 years who underwent endoscopic reconstruction of trapdoor fractures of the orbital floor between March 2000 and October 2006 at the Gil Medical Center and the Ansan Hospital, Korea University. Causes, locations, and clinical characteristics such as restriction of extraocular muscle movement were reviewed retrospectively. RESULTS: Ten of 18 patients (55.6%) exhibited nausea and vomiting, which rapidly resolved after surgery. Surgery was undertaken within 2 weeks after injury (82.3%), and most of the extraocular muscle movement restrictions improved within 2 months postoperatively. Temporary postoperative hypertropia occurred in 5 floor fractures (5/16, 31.2%). CONCLUSIONS: Trapdoor fractures of the orbital floor revealed a high incidence of persistent diplopia associated with extraocular muscle and soft tissue entrapment in the pediatric population, but actual entrapment of the muscle belly was confirmed in only 27.8% of patients endoscopically. Temporary hypertropia (31.2%) occurred in trapdoor fractures of the orbital floor but improved after 2 months of follow-up in every patient. Marked motility restriction and nausea/vomiting are predictive of trapdoor fractures. Prompt surgical intervention is needed in patients with such symptoms.

Effectiveness of canalicular laceration repair using monocanalicular intubation with Monoka tubes.

PURPOSE: This study aimed to evaluate the clinical efficacy of canalicular laceration repair using monocanalicular intubation with Monoka tubes. METHODS: A total of 36 single lacerated canaliculi were repaired using monocanalicular intubation with Monoka tubes, without mucosal anastomosis of the canaliculi, and were retrospectively reviewed. Demographic information, injury locations, associated ocular injuries, complications and outcomes were analysed. RESULTS: Mean patient age was 34 years (range 1-64 years). Tubes were removed at a mean of 4.2 months (range 3-6 months). There were 26 lower canalicular lacerations (72%) and 10 upper canalicular lacerations (28%). Overall, 34 of 36 cases (92%) showed improvement in symptoms and exhibited positivity on the dye disappearance test at 4-12 months after the procedure (mean 7.8 months). In total, 21 patients (58%) achieved complete success, 13 patients (36%) achieved partial success and two patients (6%) suffered surgical failure. Complications were seen in five cases and included two early tube protrusions, two punctal slits and one punctal granuloma. CONCLUSIONS: Monocanalicular intubation with Monoka tubes leads to successful outcomes without significant complications and offers an alternative to bicanalicular intubation in the treatment of monocanalicular lacerations.
