Summary
Endoscopic optic nerve decompression shows promise for direct traumatic optic neuropathy (TON). Early surgery within 72 hours yields the best visual improvement, while later interventions offer less benefit.
Area of Science:
- Ophthalmology
- Neurosurgery
- Otolaryngology
Background:
- Traumatic optic neuropathy (TON) is a severe condition with poor prognosis and no standardized treatment.
- TON can be direct (avulsion, laceration, compression) or indirect (increased pressure, ischemia).
Purpose of the Study:
- To assess visual improvement in direct TON patients undergoing endoscopic optic nerve decompression.
- To evaluate the impact of surgical timing on visual outcomes in direct TON.
Main Methods:
- Retrospective study of 32 patients with direct TON undergoing endoscopic optic nerve decompression over 10 years.
- Preoperative and postoperative visual assessments with a 3-month follow-up.
Main Results:
- Complete visual improvement in 17% of patients when surgery was performed within 72 hours.
- Partial improvement in 31% of patients when surgery was done between 3-7 days.
- No improvement observed in patients operated on after 7 days.
Conclusions:
- Endoscopic optic nerve decompression is a safe, minimally invasive option for direct TON.
- Timeliness of surgery is a critical prognostic factor for visual recovery in TON.
- Preoperative visual status also influences outcomes in TON patients.

01:27Open Angle Glaucoma: Treatment
520
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.

01:28Angle Closure Glaucoma: Treatment
613
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:25Glaucoma: Overview
679
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
