Summary
Intense pulsed light (IPL) combined with low-level light therapy (LLL) effectively improved lipid layer thickness and reduced symptoms in patients with meibomian gland dysfunction (MGD). This safe treatment offers a promising therapeutic option for MGD management.
Area of Science:
- Ophthalmology
- Ocular Surface Disease
- Medical Technology
Background:
- Meibomian gland dysfunction (MGD) is a common condition affecting the ocular surface.
- Altered lipid layer and meibomian gland structure characterize MGD.
- Effective treatment options for MGD are continuously sought.
Purpose of the Study:
- To evaluate the clinical outcomes of combined intense pulsed light (IPL) and low-level light therapy (LLL) in patients with MGD.
- To assess the safety and efficacy of this combined therapeutic approach.
Main Methods:
- A prospective study involving MGD patients with specific diagnostic criteria.
- Treatment involved a combination of IPL and LLL.
- Multimodal assessments were conducted pre-treatment, and at 2-3 weeks and 6 months post-treatment.
Main Results:
- Significant improvement in lipid layer thickness (LLT) was observed 6 months post-treatment.
- Ocular Surface Disease Index (OSDI) scores decreased significantly, indicating symptom reduction.
- Schirmer test (ST) improved, while tear osmolarity (OSM) worsened; other parameters showed no significant change.
- No adverse effects were reported during the study.
Conclusions:
- Combined IPL and LLL therapy is effective and safe for managing MGD.
- The treatment successfully enhances lipid layer thickness and alleviates patient symptoms.
- This approach represents a valuable addition to MGD treatment modalities.

Open Angle Glaucoma: Treatment
772
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.

Angle Closure Glaucoma: Treatment
903
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...
