Air-bags have received widespread support as an effective means of enhancing automotive safety, and they are becoming more common as standard automobile equipment on many cars. Although air-bag induced ocular injuries are rare, they present a serious concern because of the possibility of permanent damage or visual impairment. To date, most reports have investigated ocular injury from high velocity motor vehicle accidents and reports of ocular injury from low speed motor vehicle accidents have been rare. We describe a patient who sustained severe ocular injury, including periorbital fracture, hyphema, vitreous hemorrhage, and choroidal rupture of the macular area, due to an inflated air-bag in a low speed motor vehicle accident.

Aicardi syndrome is a severe congenital disorder characterized by infantile spasms, chorioretinal lacunae, and agenesis or hypogenesis of the corpus callosum. A 6 month old female had developed abnormal eye movement and seizures of the complex partial type and myoclonic type. MRI pictures of the patient revealed the presence of genu associated with agenesis of the rest of corpus callosum. A funduscopic examination revealed bilateral small, solitary, pale areas with sharp borders, some of which had minimal surrounding pigmentation (chorioretinal lacunae), especially clustered around the disc, and they were more prominent on the left side. We report here on the unusual findings of a complex partial seizure, myoclonic seizure and the atypical EEG finding in addition to the well-known characteristic clinical and imaging findings of a patient with Aicardi syndrome.

This study analyzed a hospital-based study to investigate the incidence and clinical features of ocular traumatic emergencies in Korea. Over a 6-year period, 1809 patients with ocular traumatic emergency each individually underwent clinical study including subject characteristics, type of ocular emergency, disease severity, etiology of ocular trauma, injury location, cause of decreased visual acuity, management of ocular injury, and final visual acuity. The homogeneity of each finding of the clinical features of ocular traumatic emergency was tested by an X2 test at a 95% level of certainty. During follow-up periods ranging from 3 days to 23 months (mean 2.0 months), the 1809 patients with ocular traumatic emergency, 1183 males (65.4%) and 626 females (34.6%), were studied. The incidence of ocular emergencies peaked in the third decade of life, irrespective of gender (P< 0.05). Corneal abrasion was the most common etiology among 1, 552 (85.8%) closed injuries, and corneal laceration among 257 (14.2%) open injuries (P< 0.05). There were 542 cases (30%) of severe ocular injury, such as penetrating ocular injury, blow out fracture, and intraocular foreign body (IOF), and 1267 (70%) of less severe ocular injury, such as superficial ocular injury or contusion. The most common etiology of severe ocular injury was penetrating ocular injury, and that of less severe injury was corneal injury (P< 0.05). The main causative activity of ocular injuries was work in 631 cases (34.9%), assault in 398 (22.0%), play in 278 (15.4%), traffic accidents in 145 (8.0%) and sports in 128 (7.1%). Five hundred and fifty-four cases (32.5%) underwent surgical intervention. There was an improvement of visual acuity in 502 cases (70.1%), no change in 122 (17.0%), and worsening in 92 (12.9%). We suggest that preventive educational measures be instigated at workplaces to reduce the incidence of ocular traumatic emergency, especially severe ocular injury.

Korean Journal of Ophthalmology 2004;18(1):65-69
This is a report of an atypical case of progressive outer retinal necrosis (PORN) and the effect of highly active antiretroviral therapy (HAART) on the clinical course of viral retinitis in an acquired immunodeficiency syndrome (AIDS) patient. A 22-year-old male patient infected with human immunodeficiency virus (HIV) presented with unilaterally reduced visual acuity and a dense cataract. After cataract extraction, retinal lesions involving the peripheral and macular areas were found with perivascular sparing and the mud-cracked, characteristic appearance of PORN. He was diagnosed as having PORN based on clinical features and was given combined antiviral treatment. With concurrent HAART, the retinal lesions regressed, with the regression being accelerated by further treatment with intravenous acyclovir and ganciclovir. This case suggests that HAART may change the clinical course of PORN in AIDS patients by improving host immunity. PORN should be included in the differential diagnosis of acute unilateral cataract in AIDS patients.

We retrospectively evaluated the clinical characteristics and surgical outcomes of 20 pseudophakic retinal detachment (RD) patients (20 eyes) and 17 aphakic RD patients (17 eyes). Males were predominated in both groups. The time interval between cataract extraction and RD was 31 months on average in the pseudophakic group, 32 months with intact posterior capsule and 27 months with ruptured posterior capsule, and 148 months in the aphakic group. In 50% of cases with ruptured posterior capsule in the pseudophakic group, RD occurred within 1 year. The anatomic success rate was 95% in the pseudophakic group and 88% in the aphakic group. The most common cause of failure was the development of proliferative vitreoretinopathy. Visual acuities more than 20/40 after RD surgery were found in 13 pseudophakic (65%) and 6 aphakic (36%) eyes. Aphakic patients were more inclined to have silent RD than pseudophakic patients because of their poor visual acuity. Post-operative follow-up is required especially for the first 1 year in cases of damaged posterior capsule due to the high incidence of RD during this period.

A 45-year-old man with retinitis pigmentosa (RP), who had undergone uneventful extracapsular cataract extraction (ECCE) in his right eye eight years previously, and phacoemulsification in his left eye six years previously, had spontaneously dislocated intraocular lenses (IOL) within the capsular bag in both eyes one month apart. We removed the dislocated IOLs, and performed anterior vitrectomy and scleral fixation of the new IOLs. Mild contraction of the capsular bags and uneven distribution of the zonular remnants' clumps along the equator of the capsules were found by scanning electron microscopic (SEM) examination. In this study, we propose the correlation between RP and zonular weakness. To our knowledge, this is the first case report of bilateral spontaneous dislocation of IOLs within the capsular bag of an RP patient.

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.

Neovascularization at the disc (NVD) is the most serious complication in diabetic retinopathy, and leads to vitreous hemorrhage and tractional retinal detachment. We report two cases of spontaneous regression of NVD in proliferative diabetic retinopathy. Two men (31 and 46 years old) with diabetes had NVD in both eyes. They were treated with panretinal photocoagulation on the left eye first, but their right eyes went untreated, because they did not revisit our clinic for several months. Fortunately, on revisit, their neovascularization had disappeared a few months later in both eyes, including their untreated right eyes. We could not find any specific causes for the spontaneous regression of the new vessels.

PURPOSE: To report a case of third, fourth, and six cranial nerve palsies with antiphospholipid syndrome (APS). METHODS: Medical records of a 16 year old female diagnosed with idiopathic intracranial hypertension (IIH) in primary APS were reviewed. RESULTS: A 16 year old female presented with headache and diplopia. Ocular examinations revealed marked bilateral disc edema. She was unable to depress, adduct, and abduct in left eye and had limited abduction in the right eye. Cerebrospinal fluid had a normal composition and a pressure of 400 mmH2O. Lupus anticoagulant and IgG anticardiolipin antibody were positive. There was no clinical evidence of other autoimmune disease. Brain magnetic resonance (MR) imaging, MR angiography, and conventional angiogram with venous phase were normal. She was diagnosed with bilateral sixth, and left third and fourth cranial nerve palsies secondary to idiopathic intracranial hypertension in primary APS. CONCLUSIONS: To our knowledge this is the first reported case of concurrent third, fourth, and sixth cranial nerve palsies in a patient with primary APS.

Korean Journal of Ophthalmology 2006;20(1):70-75
PURPOSE: A case study and literature review of alveolar rhabdomyosarcoma (RMS) in an adult. METHODS: A 48-year-old male patient presented at our clinic complaining of proptosis that had persisted for 2 weeks in his left eye. A computed tomography (CT) scan revealed a destructive soft-tissue mass in the left ethmoid sinus with invasion of the left orbit and compression of the medial rectus muscle. Endoscopic intranasal biopsy revealed alveolar RMS. Conservative debulking and orbital wall decompression were performed. RESULTS: Immunohistochemical testing was positive for desmin, S-100, and smooth muscle actin (SMA), supporting the diagnosis of RMS. Since ipsilateral cervical and spinal metastasis was detected, systemic treatment was administered simultaneously. CONCLUSIONS: Although rarely found in adults, RMS should be considered in the differential diagnosis of orbital tumors. Immunohistochemical analysis plays an important role in the definitive diagnosis of RMS.
