Summary
Liquid nitrogen cryotherapy effectively treated conjunctival lymphangiectasia, resolving symptoms within two weeks. Recurrence was noted in some cases, suggesting potential need for repeat treatments for this ocular condition.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Conjunctival lymphangiectasia presents as dilated lymphatic vessels on the conjunctiva.
- Symptoms include epiphora, irritation, redness, and blurred vision.
- Treatment options for conjunctival lymphangiectasia can be limited.
Purpose of the Study:
- To evaluate the efficacy of liquid nitrogen cryotherapy for conjunctival lymphangiectasia.
- To report outcomes from a case series of patients treated with this method.
Main Methods:
- Four patients with biopsy-proven conjunctival lymphangiectasia underwent treatment.
- A 1.5-mm cryoprobe was used with a double freeze-thaw method.
- Follow-up included examinations at various intervals post-treatment.
Main Results:
- All five treated eyes showed symptom and sign resolution within two weeks.
- Recurrence of lymphangiectasia occurred in three eyes at 6 months, 1 year, and 3 years.
- The average follow-up duration was 24.5 months.
Conclusions:
- Liquid nitrogen cryotherapy appears to be an effective alternative treatment for conjunctival lymphangiectasia.
- Repeat cryotherapy sessions may be necessary for sustained resolution.

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.
