Summary
Microsecond pulsing laser therapy (MLT) effectively treats central serous chorioretinopathy (CSCR) with choroidal neovascularization (CNV), resolving subretinal fluid in 61% of patients. This safe treatment option shows significant efficacy for CSCR complicated by small CNV.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Laser Therapy
Background:
- Central serous chorioretinopathy (CSCR) can be complicated by choroidal neovascularization (CNV).
- Effective management of CSCR with CNV is crucial for visual preservation.
- Novel therapeutic approaches are needed to address this condition.
Purpose of the Study:
- To evaluate the efficacy and safety of microsecond pulsing laser therapy (MLT) for CSCR complicated by CNV.
- To determine the rate of subretinal fluid (SRF) resolution after MLT.
- To assess any adverse effects associated with MLT in this patient cohort.
Main Methods:
- A randomized controlled trial was conducted with patients diagnosed with CSCR and CNV.
- The study group received MLT targeting the CNV area, while the control group received sham treatment.
- Follow-up lasted at least six months, with SRF resolution as the primary outcome measure.
Main Results:
- In the study group (n=23), 60.9% achieved complete SRF resolution, 21.7% showed partial reduction, and 17.4% had no improvement.
- None of the patients in the control group (n=12) showed SRF resolution (p=0.0018).
- No adverse events, including changes in CNV size or visual acuity decline, were reported.
Conclusions:
- Microsecond pulsing laser therapy (MLT) is an effective and safe treatment for CSCR with relatively small CNV.
- MLT achieves complete SRF resolution in a significant majority of treated eyes.
- This laser modality offers a promising therapeutic option for specific cases of CSCR-associated CNV.

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.

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...
