Summary
Endoscopic third ventriculostomy (ETV) is an alternative treatment for hydrocephalus. However, this procedure can lead to vision problems like double vision and eye misalignment in adolescents.
Area of Science:
- Neurosurgery
- Ophthalmology
Background:
- Traditionally, ventriculoperitoneal shunts were the primary treatment for noncommunicating hydrocephalus.
- High rates of shunt failure and complications have prompted exploration of alternative neurosurgical techniques.
- Endoscopic third ventriculostomy (ETV) is increasingly utilized for hydrocephalus management, particularly after shunt failure.
Observation:
- This report details two adolescent patients who underwent endoscopic third ventriculostomy.
- Following the procedure, both patients exhibited new-onset ocular motility issues.
Findings:
- The adolescents developed exotropia (outward turning of the eye), hypertropia (upward turning of the eye), and diplopia (double vision).
- These symptoms suggest a potential link between ETV and specific visual disturbances.
Implications:
- Ocular complications should be considered when evaluating patients post-ETV.
- Further research is needed to understand the mechanisms and prevalence of visual disturbances after endoscopic third ventriculostomy.
- Neurosurgeons and ophthalmologists should collaborate to manage these adverse events.

01:28Angle Closure Glaucoma: Treatment
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...
01:27Open Angle Glaucoma: Treatment
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.
