Retinal Laser: A Precise Tool for Treating Retinal Diseases
Retinal laser is a precise and effective treatment method for a wide range of retinal diseases. In this procedure, a high-intensity and highly focused laser beam is used to target damaged areas of the retina. This beam causes thermal changes in the target tissue, ultimately aiding in the treatment of the disease.
 
Which diseases are treated with retinal laser?
Diabetic retinopathy: One of the most common applications of retinal laser is in the treatment of diabetic retinopathy. In this disease, the blood vessels in the retina are damaged, which can lead to fluid leakage or bleeding. The laser seals the leaking vessels, preventing disease progression and vision loss.
Retinal tears: If a tear occurs in the retina, the laser creates a scar around the tear to prevent it from spreading and causing a retinal detachment.
Retinal tumors: Some benign retinal tumors can be treated with laser.
Macular edema: In some cases, laser is used to treat macular edema, which causes central vision blurring.
 
Benefits of retinal laser
High precision: The laser targets damaged areas with great precision, avoiding damage to healthy tissues.
High speed: Laser treatment is usually quick and the procedure time is short.
Minimal pain: Retinal laser is usually performed with local anesthesia, and the patient experiences little pain.
No general anesthesia required: In most cases, general anesthesia is not necessary.
Outpatient procedure: The procedure is usually performed on an outpatient basis, and the patient can return home after a short time.
 
Stages of retinal laser procedure
Local anesthesia: Before the procedure begins, anesthetic drops are instilled into the eye.
Eye fixation: A special instrument is placed on the eyelid to keep the eye still and prevent movement.
Laser irradiation: The doctor uses the laser device to target the damaged areas of the retina.
End of procedure: After the laser procedure is completed, eye drops are prescribed, and the patient rests for a short time.
 
Post-retinal laser care
After the laser procedure, the doctor will provide instructions for eye care, which may include:
 
Using eye drops
Avoiding strenuous activity
Regular follow-up visits with the doctor to monitor the eye's condition
Who can undergo retinal laser?
Many people with retinal diseases may be suitable candidates for laser treatment. However, the decision to undergo laser treatment should be made by a qualified eye specialist. Retinal laser is an effective treatment method, but it does not guarantee complete vision recovery. The outcome of treatment depends on the type of disease, its severity, and other factors.
 
 
World Hepatitis Day 2024

A Silent Threat, It Is Time to Action

A Silent Threat, It's Time to Action - World Hepatitis Day 2024

The World Health Organization has designated July 28th as World Hepatitis Day to raise awareness about this disease, encourage vaccination, promote early diagnosis, and facilitate effective treatment for hepatitis. Early detection of hepatitis is crucial as prompt treatment can prevent the disease from progressing to cirrhosis or liver cancer.

The World Health Organization (WHO) has designated July 28th as World Hepatitis Day to raise global awareness about hepatitis, a group of infectious liver diseases. The day aims to encourage vaccination, promote early diagnosis, and facilitate effective treatment.
Early detection of hepatitis is crucial as prompt treatment can prevent the disease from progressing to cirrhosis or liver cancer. The ultimate goal is to reduce new hepatitis cases by 90% and hepatitis-related deaths by 65% by 2030. Reflecting this ambition, the WHO's slogan for 2024 is "It's time to action."
 
What is Hepatitis?
Hepatitis is the inflammation of the liver. This inflammation can be caused by viruses, chemicals, medications, or certain autoimmune diseases. The most common types of hepatitis are viral hepatitis caused by the hepatitis A, B, and C viruses.
 
Consequences of Hepatitis
The widespread prevalence of hepatitis can impose a significant economic burden on governments and communities. The high costs associated with treatment and the decreased productivity of the workforce can negatively impact a country's economic growth. Furthermore, individuals living with hepatitis may face long-term health problems and a reduced quality of life.
 
Transmission of Hepatitis
Hepatitis A: Transmitted through contaminated food or water, or direct contact with an infected person.
Hepatitis B: Transmitted through contact with infected blood or bodily fluids, such as unprotected sex or sharing needles.
Hepatitis C: Primarily transmitted through contact with infected blood, such as injecting drugs with contaminated needles or receiving contaminated blood products.
 
Symptoms of Hepatitis
While symptoms can vary, common signs of hepatitis include:
Extreme fatigue
Loss of appetite
Nausea and vomiting
Abdominal pain
Jaundice (yellowing of the skin and eyes)
Dark urine
Pale stools
 
Prevention and Treatment
To combat hepatitis:
Vaccination: Effective vaccines are available for hepatitis A and B.
Testing: Regular testing for early detection.
Safe behaviors: Practicing good hygiene, using condoms, and avoiding sharing needles.
Education: Raising public awareness.
Support: Providing support for those living with hepatitis.
Treatment for hepatitis depends on the specific virus and stage of the disease. While some cases resolve on their own, antiviral medications are available for hepatitis B and C.
 
Conclusion
Despite the challenges, the future of the fight against hepatitis is promising. Advancements in diagnosis, treatment, the development of new vaccines, and increased public awareness are all contributing to improving the lives of those affected by hepatitis. With global cooperation and investment, we can significantly reduce the burden of hepatitis by 2030.
