BACKGROUND: Although recent evidence suggests a controversy effect of steroids in the management of indirect traumatic optic neuropathy (TON), steroid pulse therapy remains one of the reasonable treatments for patients with indirect TON. It is thought that microcirculatory spasms, edema, and nerve cell necrosis can be prevented or reduced by large doses of steroids. The aim of this study is to analyze the predisposing factors for the recovery of patients with indirect TON who were treated with steroid pulse therapy...

REVIEW
Rupesh Agrawal, Mehul Shah, Kamiar Mireskandari, Goh Kong Yong
Ocular trauma is a topic of unresolved controversies and there are continuous controversial and debatable management strategies for open-globe injuries (OGIs). International classification of ocular trauma proposed almost 15 years ago needs to be reviewed and to be more robust in predicting the outcome in the setting of OGIs. Anterior segment trauma involves controversies related to patching for corneal abrasion, corneal laceration repair, and medical management of hyphema. Timing of cataract surgery and intraocular lens implantation in the setting of trauma is still debated worldwide...

BACKGROUND: Traumatic optic neuropathy (TON) is an important cause of severe loss of vision due to blunt or penetrating head trauma. The pathogenesis of TON remains unclear, and there are several potential causes for the observed loss in vision. Endoscopic optic nerve decompression (EOND) has been reported to improve the visual prognosis in TON cases, but its efficacy remains controversial. It is important to investigate the therapeutic efficacy of EOND in the treatment of TON and to evaluate the relevant prognostic factors...

The outcome of traumatic optic neuropathy was evaluated following penetrating and blunt injuries to assess the effect of treatment options, including high-dose steroids, surgical intervention, and observation alone. Factors that affected improvement in visual acuity were identified and quantified. Sixty-one consecutive, nonrandomized patients presenting with visual loss after facial trauma between 1984 and 1996 were assessed for outcome. Pretreatment and posttreatment visual acuities were compared using a standard ophthalmologic conversion from the values of no light perception, light perception, hand motion, finger counting, and 20/800 down to 20/15 to a logarithm of the minimum angle of resolution (log MAR)...

The problem of pathogenesis and effective treatment of traumatic optic neuropathy (TON) is still an open question. According to current opinions the immediate results of conservative treatment with megadose corticosteroids are similar to those obtained with surgical decompression. No data on late results of both modes of treatment are at present available. This study was undertaken to assess the late results of conservative treatment of traumatic optic neuropathy. The clinical material comprised 15 patients (3 women and 12 men, age 14-64 years), who developed clinical symptoms of TON as a consequence of closed head trauma...

Traumatic optic neuropathy is one of true ophthalmic emergencies and there is no proven form of treatment for traumatic optic neuropathy. Here we were presented with 30 cases of sudden visual loss following blunt eye trauma seen in Kaohsiung Medical College Hospital, Taiwan from April 1994 to March 1997. We analyze the treatment style, visual acuity, elapsed time since injury and orbit computed tomography retrospectively. Among them, 21 cases received intravenous methylprednisolone treatment, 2 cases received oral prednisolone, 2 cases underwent optic canal decompression in addition to intravenous methylprednisolone and 5 cases were carefully monitored without any kind of treatment...

BACKGROUND: Indirect traumatic optic neuropathy represents a severe, potential vision-threatening disease process that requires close interdisciplinary cooperation for treatment. In general, any therapy has been discussed controversially in the literature. Based upon experiences with spinal cord trauma, high-dose steroid therapy is recommended initially to minimize secondary consequences following orbital trauma. The usefulness of surgical decompression of the optic nerve has been confirmed in several studies but is still not recommended in principle...

UNLABELLED: The therapy of traumatic optic neuropathy remains controversial. Some authors recommend observation and others, the use of megadose corticosteroids or surgical decompression of the optic nerve. Improvements in visual acuity from no light perception (NLP) preoperatively to close to normal visual acuities have been reported after transethmoidal decompression and systemic steroids. The transnasal microscopic approach offers safe and effective access to the optic canal. MATERIALS AND METHODS: Retrospectively 15 patients (13 men/2 women) ranging in age from 17 to 67 years, who were surgically decompressed in the Ear-Nose-Throat Department between 1989 and 1994, were analyzed...

From 1968 through 1984, 110 cases (113 eyes) with indirect traumatic optic neuropathy were seen at the Department of Ophthalmology and Otorhinolaryngology of the Kobe University Hospital; 43 eyes were treated nonsurgically with steroid and 70 eyes were operated on by the endonasal-transethmoidal method of optic canal decompression. By comparison of the visual improvements in the two groups, the effectiveness of the surgical treatment was evaluated. In the nonsurgical group, 19 eyes showed a visual improvement, giving an overall improvement rate of 44...
