Summary
Trapdoor fractures can cause double vision due to muscle entrapment. This case shows spontaneous resolution of diplopia, suggesting observation may be suitable when emergent conditions are ruled out.
Area of Science:
- Ophthalmology
- Trauma Surgery
Background:
- Trapdoor fractures, a type of orbital floor fracture, involve muscle entrapment and can lead to ischemia and necrosis.
- Immediate surgery is typically recommended for symptomatic persistent diplopia or clinical evidence of entrapment.
Observation:
- A 15-year-old female presented with diplopia after ocular trauma.
- Initial CT scans were negative for fracture, but a positive forced duction test suggested entrapment.
- MRI ruled out extraocular muscle edema or inflammation.
Findings:
- The patient experienced spontaneous resolution of diplopia within two weeks.
- A repeat forced duction test became negative, confirming the resolution of entrapment.
Implications:
- Observation may be a viable management option for suspected trapdoor fractures with limited ocular movement.
- This approach is appropriate when imaging excludes emergent conditions requiring immediate surgical intervention.

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Angle Closure Glaucoma: Treatment
1.6K
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...

Glaucoma: Overview
1.7K
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...
