1/120. Rotoextractor evacuation of total hyphema.

    hyphema was created in ten albino rabbits and removed within an hour by the Douvas Rotoextractor. All the blood was gone from each eye within 48 hours and there was no evidence of damage to iris, cornea or lens after six weeks. One patient underwent Douvas Rotoextractor removal of a hyphema that was causing increased intraocular pressure and corneal staining. Three months postoperatively, vision was 6/7.5 and intraocular pressure was controlled.

2/120. Photocoagulation of iris nevus to control recurrent hyphema.

    PURPOSE: To report a case of recurrent hyphema caused by an iris nevus that was successfully treated with photocoagulation. METHOD: Case report. In a 30-year-old woman with recurrent hyphema secondary to an iris nevus, photocoagulation was applied to the iris nevus. RESULTS: Before photocoagulation of the iris nevus, the patient had increasing frequency of hyphema episodes. After treatment, no hyphema episodes occurred during 13 months of observation. CONCLUSION: Photocoagulation of the surface of an iris nevus may prevent recurrent hyphema.

3/120. hyphema associated with pupillary dilation in a patient with exfoliation glaucoma and warfarin therapy.

    PURPOSE: To describe an unusual hemorrhagic complication associated with pupillary dilation in a patient with exfoliation glaucoma taking anticoagulation therapy. methods: A 78-year-old woman with bilateral exfoliation glaucoma who was receiving warfarin, 2 mg daily, for systemic anticoagulation developed acute visual loss in the right eye several hours after pupillary dilation. RESULT: Examination disclosed bilateral advanced exfoliation glaucoma, localized vascularized iridolenticular adhesions in the right eye, and a 4-mm layered hyphema in the right eye. CONCLUSION: patients with exfoliation glaucoma and vascularized posterior synechiae who are receiving anticoagulation therapy are at increased risk for visually significant spontaneous hyphema after pupillary dilation.

4/120. eye injuries associated with paintball guns.

    AIMS: This study identifies the various types of ocular injuries sustained after blunt trauma with a paintball fired from a paintball gun. methods: We report two patients who sustained injury to an eye after being shot with a paintball and review similar cases presented in the world literature. The type of injury sustained and the final visual acuity obtained after a paintball hit to the eye are examined. RESULTS: The two boys presented were hit in the eye with a paintball resulting in lens subluxation, hyphema formation, and angle recession. cataract extraction was required in both cases. One boy also had an optic neuropathy and a choroidal rupture. A review of the literature reveals a variety of injuries occur after a paintball hit to the eye. In some of the cases, the damage to the eye has led to loss of vision and at times loss of the eye. CONCLUSIONS: Paintball guns can cause devastating ocular injuries. Wearing protective eye and face gear during this game is essential. We recommend that an anti-fog face mask with a one-piece polycarbonate eye shield be worn by those participating in paintball games.

5/120. hyphema caused by a metallic intraocular foreign body during magnetic resonance imaging.

    PURPOSE: To report a 63-year-old man with a retained intraocular foreign body who developed a hyphema during magnetic resonance imaging (MRI) of the brain. methods: Case report and review of the current literature on ocular injury caused by intraocular foreign bodies when subjected to an electromagnetic field. RESULTS: Our patient underwent a brain MRI, and the intraocular foreign body caused a hyphema and increased intraocular pressure. The presence and location of the intraocular foreign body were determined by computed tomography (CT). CONCLUSION: magnetic resonance imaging can cause serious ocular injury in patients with ferromagnetic intraocular foreign bodies. This case demonstrates the importance of obtaining an occupational history, and, when indicated, a skull x-ray or CT to rule out intraocular foreign body before an MRI study.

6/120. iris varix simulating an iris melanoma.

    iris varix is rare and little is known about its clinical characteristics. We treated a thrombosed iris varix that simulated an iris melanoma. A 53-year-old man developed a dark brown iris mass and hyphema in his left eye. Ultrasound biomicroscopy revealed a circumscribed mass of the iris stroma. Because of suspicion for melanoma, it was removed by sector iridectomy. Histopathologic examination disclosed an extensive focus of stromal hemorrhage, partially surrounded by endothelial cells that showed immunoreactivity to vascular markers. The histopathologic diagnosis was thrombosed iris varix. iris varix is a rare condition that should be included in the differential diagnosis of iris melanoma.

7/120. Partial dislocation of laser in situ keratomileusis flap by air bag injury.

    PURPOSE: A patient developed significant corneal complications from air bag deployment, 17 months after laser in situ keratomileusis (LASIK). methods: Case report, slit-lamp microscopy, and review of the medical literature. RESULTS: A 37-year-old woman underwent bilateral LASIK with resultant 20/20 uncorrected visual acuity. Seventeen months later, she sustained facial and ocular injuries from air bag deployment during a motor vehicle accident. Examination revealed bilateral corneal abrasions, partial dislocation of the right corneal LASIK flap, and a hyphema in the right eye. The LASIK flap was realigned, but recovery was complicated by a slowly healing epithelial defect and flap edema. One month following the injury, epithelial ingrowth beneath the LASIK flap was noted. Surgical elevation of the flap and removal of the epithelial ingrowth was performed. Eight months later, epithelial ingrowth was absent and the visual acuity was 20/40. Residual irregular astigmatism necessitated rigid gas permeable contact lens fitting to achieve 20/20 visual acuity. CONCLUSIONS: air bags may cause significant ocular trauma. The wound healing response of LASIK allows corneal flap separation from its stromal bed for an indeterminate time after surgery. Discussion of the possible risk of corneal trauma as part of informed consent prior to LASIK may be appropriate.

8/120. Air bag-associated ocular trauma in children.

    OBJECTIVE: To describe a series of children with ocular injuries related to air bag deployment. DESIGN: Retrospective, observational case series. PARTICIPANTS: Seven patients with ocular injuries sustained in motor vehicle accidents in which air bags were deployed. methods: review of medical records. RESULTS: All patients had periocular contusions. Minor injuries included corneal abrasions (n = 5), superficial eyelid laceration (n = 1), and traumatic iritis (n = 2). Serious injuries included corneal edema (n = 1) and a traumatic hyphema with secondary glaucoma and cataract (n = 1). The latter patient required surgery. All other injuries resolved with medical therapy. All patients recovered normal visual acuity. CONCLUSIONS: Serious ocular injuries in children may result from air bag deployment. Most such injuries are minor and resolve without sequela. It is recommended that infants and children travel in the rear seat of automobiles to minimize their risk of injury.

9/120. Herpes zoster sine herpete presenting with hyphema.

    PURPOSE: To report a case of herpes zoster sine herpete presenting with hyphema. methods: A 69-year-old man was referred for traumatic hyphema and corneal edema in his left eye after a sandblast exposure three weeks previously. Slit-lamp examination demonstrated hyphema, anterior chamber inflammation, mid-dilated pupil, impaired corneal sensation, and high intraocular pressure, without any facial skin lesions. iris fluorescein angiography revealed tortuosity and extensive occlusion of iris vessels. The patient was treated with oral acyclovir and intensive topical steroids with a presumed diagnosis of severe herpes zoster uveitis. RESULTS: Clinical findings improved dramatically within several days. Typical sectorial iris atrophy with pupillary sphincter dysfunction and complete loss of corneal sensation developed after the resolution of intraocular inflammation. CONCLUSION: herpes zoster should be considered in patients with uveitis and hyphema even in the absence of typical skin rash.

10/120. Transcorneal oxygen therapy for glaucoma associated with sickle cell hyphema.

    PURPOSE: To study three patients with glaucoma caused by sickle cell hyphema who were successfully treated with transcorneal oxygen therapy. methods: case reports. Three patients with increased intraocular pressure caused by sickle cell hyphema were administered transcorneal oxygen therapy using humidified oxygen at a flow rate that ranged from 1 to 3 l/minute. RESULTS: All three patients had a dramatic reduction in their intraocular pressure within hours of receiving oxygen therapy. No complications were associated with the oxygen therapy. CONCLUSION: Transcorneal oxygen therapy can reduce intraocular pressure in patients with glaucoma from sickle cell hyphema. Further study is warranted to evaluate this new therapy.
