Background:The purpose of this study was to determine the predictive value of flash visual-evoked potentials (VEP), relative afferent pupillary defect, and presence of orbital fractures in patients with traumatic optic neuropathy.Methods:A prospective study was conducted in 15 patients with indirect traumatic optic neuropathy. All patients underwent a thorough ophthalmic examination. Initial visual acuity, final visual acuity, and relative afferent pupillary defect were determined, and visual acuity was converted into logMAR units. We performed flash VEP and an orbital computed tomography scan in all patients.Results:There was a good correlation between relative afferent pupillary defect and final visual acuity (r = −0.83), and better initial visual acuity could predict better final visual acuity (r = 0.92). According to findings from flash VEP parameters, there was a relationship between final visual acuity and amplitude ratio of the wave (r = 0.59) and latency ratio of the wave (r = −0.61). Neither primary visual acuity nor final visual acuity was related to the presence of orbital fractures in the orbital CT scan.Conclusion:Patients with traumatic optic neuropathy often present with severe vision loss. Flash VEP, poor initial visual acuity, and higher grade of relative afferent pupillary defect could predict final visual acuity in these patients. Presence of orbital fracture was not a predictive factor for primary visual acuity or final visual acuity.

“…88 Ocular manifestations were reported after different exposures to the drug, including both first time and chronic users. One case of autoenucleation after the abuse of this drug is also reported 89 and another of a patient who developed herpes zoster ophthalmicus after oral consumption of this drug for four days. 90 It is known that this drug is a stimulant that can temporarily decrease the immunity.…”

Illicit drugs and substances of abuse are increasingly used by adults and teenagers, with novel substances constantly becoming available. Many substances can cause ocular effects or visually threatening conditions. Current literature informing eye-care practitioners on these effects is scant. The present scoping review reports the ocular effects of most commonly used drugs and substances of abuse in the teenage and adult populations of North America. Ovid MEDLINE and Ovid EMBASE databases were searched for publications from 1980 to 2019 regarding ocular effects of drug use. The selected papers regarded human subjects, in either teenage or adult population and included all types of studies, including case reports. Publications in English or in French were included. Exclusion criteria were publications about the use of prescriptions drugs, drug withdrawal, and publications about the use of alcohol, tobacco, or cannabis. Some 241 papers were retained and analysed. The use of various drugs and substances can lead to damage to structures throughout the eye, including but not limited to corneal conditions, glaucoma and other optic neuropathies, maculopathies and endophthalmitis. The data presented in this review may help guide clinicians in their diagnosis and treatment of certain ocular conditions, which could otherwise not be linked to drug use.

“…[27] A complication commonly reported in previous cases of self-nucleation but not seen in our patient is contralateral temporal field deficit (CTFC). [6,12,15,21,28] CTFC indicates chiasmal injury from avulsion of the optic nerve at its intracranial segment or more than 4 cm proximal to the optic globe and may improve with steroids. [28,29]…”

Subarachnoid hemorrhage and internal carotid artery dissection and occlusion following self-enucleation

Self-enucleation is an uncommon type of major self-injury, which may lead to severe neurological deficits and life-threatening complications, such as subarachnoid hemorrhage (SAH) and internal carotid artery (ICA) dissection and occlusion. Our patient is a 53-year-old man with a history of bipolar disorder and schizophrenia who presented with SAH, intraventricular hemorrhage, ICA dissection and occlusion, and right cerebral infarct following self-enucleation. Despite a Glasgow Coma Score of 6 on initial presentation, he improved with conservative management. He achieved a near-complete neurological recovery, with residual left lower extremity weakness and mild confusion. Self-enucleation is a major neurologic, ophthalmologic, and psychiatric emergency with a potential for serious neurological complications and contralateral visual loss. Yet, conservative management may lead to dramatic recovery.

A Case of Autoenucleation Associated with a Contralateral Field Defect

Abstract: Contralateral visual field defect may be associated with autoenucleation. A visual field test is recommended in all cases with traumatic enucleation.
