Summary
Traumatic optic neuropathy (TON) causes severe vision loss. Surgical decompression of the optic canal (OC) may benefit select patients with bony compression or progressive vision loss, though evidence for high-dose steroids is limited.
Area of Science:
- Ophthalmology
- Neurosurgery
- Trauma Surgery
Background:
- Traumatic optic neuropathy (TON) is a significant cause of vision impairment following head and facial trauma.
- Current treatments like high-dose steroids and surgery lack definitive evidence for improving visual acuity in indirect TON.
Purpose of the Study:
- To review surgical approaches for optic canal (OC) decompression in traumatic optic neuropathy.
- To delineate surgical indications, timing, and techniques for OC decompression.
Main Methods:
- Literature review focusing on surgical interventions for TON.
- Analysis of surgical techniques for optic canal decompression.
Main Results:
- Surgical decompression is recommended for TON with direct bony compression of the optic nerve.
- It may be considered for indirect TON with progressive visual loss.
- Evidence supporting high-dose steroids for TON remains inconclusive.
Conclusions:
- Neurosurgeons must understand the specific indications, optimal timing, and techniques for OC decompression in TON.
- Surgical intervention is a critical consideration for specific TON cases, particularly those involving bony compression.

Traumatic Memory
583
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Post-traumatic Stress Disorder
558
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Open Angle Glaucoma: Treatment
997
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Treatment Resistant Cancers
3.8K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Parkinson's Disease: Treatment
1.2K
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Alzheimer's Disease: Treatment
952
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
