Summary
Ectopic lacrimal gland tissue, a rare cause of unilateral proptosis, can mimic orbital tumors in children. Surgical excision of this benign condition provides a good outcome with no recurrence.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Orbital Surgery
Background:
- Ectopic lacrimal gland tissue is an uncommon condition.
- The most frequent locations are the bulbar conjunctiva and limbal area.
- Intraorbital ectopic lacrimal gland tissue can present as proptosis, mimicking orbital neoplasms.
Observation:
- A 14-year-old girl experienced intermittent proptosis since childhood.
- Symptoms included subconjunctival hemorrhage and severe pain.
- The proptosis was caused by intraconal ectopic lacrimal gland tissue.
Findings:
- The patient underwent lateral orbitotomy with orbital mass excision.
- The ectopic lacrimal gland tissue was successfully removed.
- Post-operative follow-up at 6 months showed no recurrence.
Implications:
- This case highlights the importance of considering rare diagnoses like ectopic lacrimal gland tissue in pediatric proptosis.
- Early diagnosis and surgical intervention can lead to favorable outcomes.
- Accurate diagnosis prevents unnecessary aggressive treatments for suspected orbital tumors.

01:25Glaucoma: Overview
919
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...

01:28Angle Closure Glaucoma: Treatment
843
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...

01:17Accessory 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...

01:27Open Angle Glaucoma: Treatment
717
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.
