Summary
Micropulse laser (MPL) treatment significantly reduced retinal thickness in patients with chronic central serous chorioretinopathy (CSC). This effective treatment for CSC showed no adverse effects on visual acuity, warranting further investigation.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Laser Therapy
Background:
- Central serous chorioretinopathy (CSC) is a leading cause of vision loss with limited evidence-based treatment options.
- Recent literature suggests potential benefits of micropulse laser (MPL) treatment for CSC.
Purpose of the Study:
- To re-evaluate the efficacy of MPL treatment in patients diagnosed with chronic CSC.
- To assess the impact of MPL on retinal thickness and visual acuity in this patient group.
Main Methods:
- A prospective study included 28 patients with chronic CSC unresponsive to other treatments.
- Patients received yellow laser (577 nm) MPL treatment.
- Follow-up assessments were conducted at 6 weeks, 12 weeks, and quarterly thereafter.
Main Results:
- Mean foveal retinal thickness decreased significantly from 351.7 µm to 253.6 µm post-MPL treatment.
- Visual acuity showed no significant change, remaining stable post-treatment.
- No adverse side effects associated with MPL were observed during the study period.
Conclusions:
- MPL treatment effectively reduces retinal thickness in chronic CSC patients.
- MPL is a safe treatment option for chronic CSC, with no observed impact on visual acuity.
- Larger controlled studies are recommended to further validate these findings and explore MPL's role in CSC management.

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
