Summary
Recurrent giant conjunctival cysts can cause significant discomfort. Aspiration with 20% trichloroacetic acid (TCA) offers an effective, less invasive treatment, preventing recurrence in a challenging case.
Area of Science:
- Ophthalmology
- Ophthalmic Surgery
Background:
- Giant conjunctival cysts are rare but can cause significant discomfort and functional impairment.
- Recurrence after surgical excision is a known complication, posing a treatment challenge.
Observation:
- A 51-year-old female presented with a recurrent giant conjunctival cyst in her left eye, causing pain on eye movement.
- Previous surgical excision had not prevented recurrence, despite maintained visual acuity of 20/20 bilaterally.
Findings:
- Aspiration of the cyst followed by injection of 20% trichloroacetic acid (TCA) and irrigation resulted in complete resolution.
- No recurrence or symptoms were observed eight months post-treatment.
Implications:
- 20% TCA injection is a viable and effective treatment for recurrent giant conjunctival cysts.
- This method provides a less invasive alternative to repeat surgery, potentially reducing recurrence rates.

01:28Angle Closure Glaucoma: Treatment
435
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
391
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.
