1/15. Bilateral periopticointrascleral hemorrhages associated with traumatic child abuse.PURPOSE: To report a case of bilateral periopticoscleral hemorrhages associated with traumatic child abuse. methods: Postmortem gross examination and histopathologic studies of both eyes and the optic nerves of a 6-month-old infant who died from subdural hematoma. RESULTS: Gross examination and histopathologic step sections disclosed bilateral intrascleral hemorrhages around both optic nerves. In addition, bilateral diffuse multilayered retinal, vitreous, and sublaminar (beneath the internal limiting membrane) hemorrhages were present. CONCLUSION: Periopticointrascleral hemorrhages are characteristic of blunt head trauma and may constitute important forensic evidence in cases of suspected child abuse.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
2/15. optic nerve avulsion secondary to a basketball injury.optic nerve avulsion secondary to a basketball injury is a rare complication. The patient underwent a vitrectomy for a non-clearing vitreous hemorrhage. The nerve was partially avulsed with multiple choroidal ruptures in the fovea. It was concluded that optic nerve disorders rarely occur after basketball injuries. patients with a dense vitreous hemorrhage may benefit from a vitrectomy although the vision will be limited by the optic nerve disorder.- - - - - - - - - - ranking = 4keywords = nerve (Clic here for more details about this article) |
3/15. optic nerve avulsion from a golfing injury.PURPOSE: To describe a patient with optic nerve avulsion after being struck in the eye with a golf club. methods: A 10-year-old male was hit in the left eye by a golf club. The patient underwent full ophthalmoscopic evaluation and neuroimaging. RESULTS: The patient had no light perception in the left eye when first seen. Avulsion of the optic nerve with vitreous hemorrhage was apparent on examination. Computed tomographic imaging of the brain and orbits revealed no abnormalities. CONCLUSIONS: optic nerve avulsion from golf-related injury is more likely to occur when the impact site is between the globe and the orbital rim. rupture of the globe is more likely to occur with direct impact to it.- - - - - - - - - - ranking = 3.5keywords = nerve (Clic here for more details about this article) |
4/15. Terson syndrome: a case report suggesting the mechanism of vitreous hemorrhage.OBJECTIVE: To present a patient with Terson syndrome and to propose a mechanism for vitreous hemorrhage. DESIGN: Observational case report. PARTICIPANT: A 50-year-old woman with subarachnoid hemorrhage and unilateral vitreous hemorrhage. methods: Detailed examination with fluorescein angiography and funduscopy. MAIN OUTCOME MEASURES: Site of dye leakage on fluorescein angiography in the eye with vitreous hemorrhage. RESULTS: fluorescein angiography showed the leakage site at the margin of the disc in the eye with vitreous hemorrhage after the vitreous hemorrhage had been removed. CONCLUSIONS: The damage to peripapillary tissues demonstrated by fluorescein leakage suggests that intracranial hypertension affects peripapillary structures through the intervaginal space of the optic nerve sheath.- - - - - - - - - - ranking = 0.5keywords = nerve (Clic here for more details about this article) |
5/15. Organized vitreous hemorrhage masquerading as an optic disc melanocytoma.PURPOSE: To present a case of organized vitreous hemorrhage masquerading an optic disc melanocytoma. DISCUSSION: optic nerve head melanocytoma is a benign slightly pigmented lesion arising from the edge of the disc presenting with a filed defect. Pigmented nature of the lesion in question due to presence of haemosidrin laden macrophages led a diagnostic dilemma. Trans vitreal biopsy confirmed the diagnosis. CONCLUSIONS: Althought classical in presentation organized blood clots can masquerade a number of lesions including a melanocytoma as in the present scenario.- - - - - - - - - - ranking = 0.5keywords = nerve (Clic here for more details about this article) |
6/15. Severe visual loss caused by ocular perforation during chalazion removal.PURPOSE: To report two cases of ocular perforation during chalazion removal procedures leading to severe vision loss. DESIGN: Observational case series. methods: Two patients presented with unilateral decreased vision after chalazion removal procedures. Complete ophthalmologic examinations were performed. RESULTS: Examination revealed a cherry red spot and perforation site in the first patient. In the second patient, there was an intraocular gas bubble and ischemic retina. CONCLUSIONS: Local anesthetic injections for procedures such as chalazia removal can result in ocular perforation. We postulate that the intraocular injections led to extremely high pressures, compromising the blood supply to the retina and optic nerve. Anesthetic injections for all procedures, even chalazia removal, should be done with great caution. It is imperative to avoid injection if ocular perforation is suspected, as the high pressure may cause the majority of the visual morbidity.- - - - - - - - - - ranking = 0.5keywords = nerve (Clic here for more details about this article) |
7/15. Sudden vision loss following retinal detachment surgery.A 22-year-old man with Eales' disease with secondary rhegmatogenous retinal detachment with a break five disc diameters from the disc underwent radial scleral buckling using a silicone sponge episcleral explant with local cryopexy. Five hours after surgery the patient had no light perception. There was no intraoperative or postoperative rise of intraocular pressure or central retinal artery ischemia. Immediate removal of the explant brought a return of light perception and postoperative visual acuity improvement. The episcleral explant may have caused the direct optic nerve trauma that resulted in loss of vision.- - - - - - - - - - ranking = 0.5keywords = nerve (Clic here for more details about this article) |
8/15. Chorioretinal involvement and vitreous hemorrhage in a patient with juvenile xanthogranuloma.We describe an unusual presentation of juvenile xanthogranuloma in a 4-year-old girl. Juvenile xanthogranuloma may be associated with posterior manifestations including optic nerve and choroidal granulomas, panuveitis, and vitreous hemorrhage in the absence of the classic anterior segment manifestations.- - - - - - - - - - ranking = 0.5keywords = nerve (Clic here for more details about this article) |
9/15. Intravitreal bevacizumab (Avastin) treatment of proliferative diabetic retinopathy complicated by vitreous hemorrhage.PURPOSE: To report the short-term anatomic and visual acuity response after intravitreal injection of bevacizumab (Avastin, Genentech) in patients with proliferative diabetic retinopathy complicated by vitreous hemorrhage. methods: Two patients with vitreous hemorrhage due to proliferative diabetic retinopathy were treated with at least one intravitreal injection of bevacizumab 1.25 mg in 0.05 mL. The patients underwent Snellen visual acuity testing, ophthalmoscopic examination, and fluorescein angiography at baseline and follow-up visits. RESULTS: Both patients had proliferative diabetic retinopathy with vitreous hemorrhage extensive enough to preclude panretinal photocoagulation. Following intravitreal injection of bevacizumab both patients experienced improvement in visual acuity starting within the first week. At 1 month of follow-up one patient had 2 lines of improvement in visual acuity and the other 5 lines. Each patient had regression of retinal neovascularization at 1 month of follow-up. Repeat injection was given to one patient at the 1-month follow-up because of slight leakage from neovascularization on the nerve, and to the other patient at 3 months because the retinal neovascularization showed early signs of reperfusion. The vitreous hemorrhage in each patient showed partial resolution at 1 week and nearly complete regression at 1 month. No adverse events were observed in either patient. CONCLUSIONS: Initial treatment results of patients with vitreous hemorrhage and proliferative diabetic retinopathy did not reveal any short-term safety concerns. Intravitreal bevacizumab resulted in marked regression of neovascularization and rapid resolution of vitreous hemorrhage. The favorable short-term results suggest further study is needed in a larger group of patients.- - - - - - - - - - ranking = 0.5keywords = nerve (Clic here for more details about this article) |
10/15. Nasal retinal dragging in X-linked retinoschisis.X-linked retinoschisis is a disorder characterized by the presence of foveal schisis and often peripheral splitting of the retina in the nerve fiber layer. The accompanying complications include vitreous hemorrhage and retinal detachment, which can lead to blindness. In this report five patients who presented during infancy or early childhood had nasal retinal dragging.- - - - - - - - - - ranking = 0.5keywords = nerve (Clic here for more details about this article) |
