OBJECTIVE: To discuss the clinical features and treatment methods for simple orbital blowout fracture. METHOD: Retrospective analysis of the CT images of 16 orbital blowout fracture case, and identification of the sites, degree, patterns and features of fractures. Among the 16 cases, 2 cases adopted conservative treatment; 11 cases gained a reduction of orbital fracture through endoscopic transnasal surgery; the other 3 patients choosed endoscopic transnasal surgery and Caldwell-Luc operations. RESULT: Among 16 diplopia cases, 13 cases were completely cured, and 3 patients' vision were significantly improved. Among 11 enophthalmos cases, 10 patients were cured, and the effect of the other one was not satisfied. Among the 15 eye movement disorder cases, 13 patients' eye movement gained a full recovery, and the other 2 cases were nearly normal. All patients' vision were improved in different extents, and no one got a complication. CONCLUSION Computerized Tomography is helpful to the diagnosis of simple orbital blowout fracture. Caldwell-Luc operation with transnasal endoscope is an effective method for the treatment of orbital fractures.

Laser keratomileusis and excimer laser photorefractive keratectomy in situ are widely used therapies for treating myopia. The corrections of refractive error by glasses or contact lens result in a relatively equal refractive correction on both eyes. However, refractive surgery on a single eye can cause a focus disparity between both eyes and may result in the impairment of fusion leading to strabismus. This article aims to report a case where diplopia and esotropia occurred 1 month after laser keratomileusis (LASIK) in situ for the correction of myopia.

Extraocular muscle imbalance and diplopia after retina surgery have been previously reported, but the etiology is still controversial. In order to better understand the cause of strabismus after retinal surgery, the authors retrospectively studied 30 patients with persistent strabismus following retinal surgery and combined the result about seven patients of strabismus after retinal surgery in the previous report. Results showed multiple etiologies for the strabismus. Causes of strabismus included fat adherence syndrome (14 patients), non-specific restrictive adhesion (11), displacement of superior oblique tendon (2), scleral explant interfering with ocular motility (1), lost or slipped muscle with adhesion (2), sensory strabismus (2), macular pucker causing ectopic fovea (2), and previous strabismus before the retinal surgery (3). Knowledge of the varieties of abnormalities that can cause strabismus and diplopia will help both the retina and strabismus surgeon prevent and treat strabismus after retinal surgery.

OBJECTIVE: To study surgical techniques and clinical applications of the intranasal endoscopic combined middle meatus and expand prelacrimal recess-maxillary ainus approach for orbital fracture treatment. METHOD: A retrospective clinical analysis of 3 patients whose admitted for orbital floor fractures or medial wall fractures operated by the intranasal endoscopic middle meatus with expand prelacrimal recess-maxillary ainus approach surgical treatment was studied, and the treatment effects and the postoperative complications were analyzed. RESULT: All patients had been followed up for 6 to 12 months. All cases of diplopia symptom were disappeared, enophthalmos were totally corrected, no cases of complication were found. CONCLUSION Endonasal endoscopic combined middle meatus and expand prelacrimal recess-maxillary ainus approach for orbital fracture treatment have great and clear view. This approach with less tissue damage and high therapeutic effect makes the cost lower than other methods and complications will be decreased as well, it has a great advantage in the orbital fracture treatment.

Simulated Brown syndrome is a term applied to a myriad of disorders that cause a Brown syndrome-like motility. We encountered a case of acquired simulated Brown syndrome in a 41-year-old man following surgical repair of fractures of both medial orbital walls. He suffered from diplopia in primary gaze, associated with hypotropia of the affected eye. We performed an ipsilateral recession of the left inferior rectus muscle as a single-stage intraoperative adjustment procedure under topical anesthesia, rather than the direct approach to the superior oblique tendon. Postoperatively, the patient was asymptomatic in all diagnostic gaze positions.

Traumatic rupture of the superior oblique muscle is rare. We report a case of a 54-year-old man injured by the metal hook of a hanger, resulting in a rupture of the superior oblique muscle tendon. He complained of torsional diplopia when in the primary position. The distal margin of the superior oblique muscle was reattached to sclera 5 and 9 mm apart from the medial insertion of the superior rectus muscle. One week after the operation, torsional diplopia disappeared. However, a 4-prism diopter ipsilateral hypertropia was observed. Three months later, hypertropia gradually increased to 20 prism dioptors and the second operation was done to correct vertical diplopia.

A 28-year-old female presented with a palpable mass lesion on the superonasal aspect of her right globe and she had a progressive diplopia. She had a scleral encircling surgery with a Miragel explant (MIRA, Waltham, Mass, USA) for the tractional retinal detachment associated with pars planitis 9 years previously. On examination, she revealed restricted eye movements of her right eye. The magnetic resonance imaging documented a swelling of the Miragel explant that mimicked a periorbital mass lesion. The Miragel explant was removed and fragmentation of the explant was found intraoperatively. The removed Miragel explant was examined by a scanning electron microscopy, and this demonstrated a disintergrated and swollen structural composition of the Miragel explant. Postoperatively, her extraocular movement was almost restored and the retina remained well attached. Alterations in the structural composition of the Miragel explant results in an excessive swelling that causes a restriction of the extraocular movement, and this can mimick a periorbital mass lesion.

A 51-year old man presented with vertical and torsional diplopia after reduction of a blowout fracture at another hospital one year ago. He had no anormalies of head position and 14 prism diopters (PD) right hypertropia (RHT) in the primary position. In upgaze no vertical deviation was found, and hyperdeviation on downgaze was 35PD. Bielschowsky head tilt test showed a negative response. Distinct superior oblique (SO) and inferior rectus (IR) underaction of the right eye was noted but IO overaction was mild on the ocular version test. Double Maddox rod test (DMRT) revealed 10-degree extorsion, but fundus extorsion was minimal in the right eye.Thin-section coronal CT scan showed that there was no fracture line on the anterior orbital floor, but a fracture remained on the posterior orbital floor. Also, the anterior part of the right inferior oblique muscle was vertically reoriented and the medial portion of the inferior oblique muscle was not traced on the coronal CT scan. The patient underwent 14 mm right IO recession and 3 mm right IR resection. One month after the surgery, his vertical and torsional diplopia were eliminated in the primary position.
