Dengue is a mosquito-borne infection. The virus that causes dengue is known as the dengue virus (DENV). There are four DENV serotypes (subspecies), meaning that you might get infected four times.
Dengue is a mosquito-borne viral illness that spreads instantly in the tropical and subtropical regions of the world.
Infection with one subspecies or serotype of dengue can result in long-term immunity only to that particular serotype and not to others. Hence, the dengue virus can infect you many times.
Symptoms of dengue involve headache, high fever, rash, muscle, and joint pain. In various cases, you can have bleeding and shock, which may be life-threatening.
The most severe type of dengue infection is dengue hemorrhagic fever. It is characterized by low levels of platelets and multiple failures of organs.
A general physician in Vasant Kunj, Delhi can give treatment for dengue fevers. However, dengue is challenging to diagnose. The presumptive diagnosis takes place on general symptoms. So, many doctors prefer waiting for confirmation of the laboratory.
How Dengue Fever affects your Eyes?
- Although dengue fever symptoms and effects are known to all, the impact on the eye in dengue fever is not yet known.
- There are differences in how the dengue virus infects different retinal cells in dengue patients and how the cells react to the infection.
- Infection of the patient's retinal cells indicates how the virus can damage a patient's eye. It involves retinal swelling and inflammation.
- High fever and Low platelet count are not the only properties of dengue. It can cause congestion in the eyes and sometimes even blindness.
- Eye specialists say it is essential to diagnose eye infection in dengue patients early to reduce its effects. Eye infections are a known complication in dengue patients and, in a few cases, an initial symptom.
- In some cases, people can lose their vision because of the infection. Their eyes can become swollen and begin to bleed internally. Saving the dengue patient's sight in these cases can be difficult Still, congestion in the eyes takes place in many dengue patients, and it rarely causes blurry vision.
- Adequate data is not present on the distribution and frequency of eye disease in dengue patients. Still, researchers say that it can range anywhere around five to six per cent. It can range between 16 and 40.3 per cent for patients hospitalized with dengue, which is high.
- The onset of eye-related symptoms can range from two days when they get dengue to even five months. Many people suffer damage to the eyes when their blood platelet count drops by a considerable number.
Treatment for Dengue Fever Affecting Eyes
- There is no known treatment for the damaged retina due to dengue fever. Steroid therapy and active monitoring are the primary treatment used. In some cases, the doctors have used immunosuppressive treatment to help the patients in swift recovery.
- The exact way dengue viral infection spreads to your eye is not correctly understood. Researchers suspect several causes, involving viral factors, capillary leakage, immune mediation, stress, and bleeding.
- Eye infections in dengue patients are linked to their platelet count. It is very prevalent when the platelet count is low or high. Though symptoms are not particular, blurring of vision is the most common complaint. However, the range at which blurring affects dengue patients varies in each case.
- Ophthalmological assessment and funduscopy are a significant addition to advanced checks. However, there are no proper guidelines on the control of eye infections in dengue.
- It can range from conservative care to aggressive steroid therapy. It involves immune modulation and ophthalmological intervention. Eye infected dengue patients can make a complete or partial recovery within some time.
- More studies and screening is required to understand eye infections during dengue fever better.
