Summary
Punctal occlusion using a conjunctival flap effectively closes the lacrimal punctum in patients with dry eye. This surgical technique offers a reversible option with a high success rate and minimal complications.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Dry Eye Disease
Background:
- Dry eye disease affects a significant portion of the population.
- Punctal occlusion is a common treatment for severe dry eye.
- Existing occlusion methods may have limitations.
Purpose of the Study:
- To detail a novel punctal occlusion technique using a conjunctival flap.
- To evaluate the surgical outcomes and efficacy of this method.
Main Methods:
- A conjunctival transposition flap was used to occlude the lacrimal punctum in 30 patients.
- The technique involved superficial excision of the eyelid margin and suturing of the canalicular opening.
- Surgical results were reviewed over a mean follow-up of 4.8 months.
Main Results:
- 94% of occluded puncti (65 out of 69) remained successfully closed.
- Only 4 puncti reopened, and 2 cases required surgical reversal due to epiphora.
- No intraoperative or significant postoperative complications were reported.
Conclusions:
- Conjunctival transposition flap occlusion is an effective and reversible treatment for the lacrimal punctum.
- This method shows promise for managing severe dry eye.
- The technique offers a safe alternative for punctal occlusion.

01:28Angle 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...

274
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

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...
