As Dengue cases are soaring high in India, especially in the national capital; another dreadful aspect of it being able to cause loss of eyesight has been discovered.
As explained by a research, published in the journal “Survey of Ophthalmology” some ordinary ocular expressions due to dengue are subconjunctival, edema and retinal hemorrhages with symptoms ranging from scotomata, floaters and clouding of vision.
As reported by TOI, Dr. Bhavana Chawla, who is associated with All India Institute of Medical Sciences (AIIMS), stated that recently they had a patient who suffered from inflated eyes and internal bleeding, eventually lost his eyesight due to dengue.
He emphasized on the need for early diagnosis of dengue infection in patients, so that their eyesight could be retained.
Dr. Mukesh Mehra, who is a senior consultant at Max hospital in Patparganj, informed that dengue causes its victims to have clogging in the eyes, but hardly hazy vision.
TOI also reported that India lacks enough records on the epidemiology of eye problems in dengue sufferers, but authorities claim that patients who are hospitalized with dengue can have 16 percent to 40.3 percent of possibilities to have eye problems.
The medical journal “Survey of Ophthalmology” informed that the time when ocular symptoms become noticeable can differ between two days, but in majority of the cases, decrease in platelet counts triggers the patient to face eye problems.
It further stated that effective observation and steroid therapy modalities are some known treatments for loss of eyesight due to dengue, albeit “there is no known effective treatment for damaged retina.” It added that in certain cases, doctors trialed with “immunosuppressive therapy to hasten clinical recovery.”
According to the World Health Organization (WHO), dengue has four strongly related serotypes – DEN-1, DEN-2, DEN-3 and DEN-4, which causes the disease. If a person recovers from infection caused by one particular infection then he/she will be saved from infection by that particular serotype, permanently. However, infections from other serotypes continue to stay as a possibility and recovering from infection by one particular serotype may seem partially helpful to stop it.
WHO also reported that a recent estimate showed that 390 million dengue infections occur annually every year, of which 96 million with severe conditions. In fact, another recent research said that 3900 million people, spread around 128 nations, are suffering from dengue at present.
Post 1970, dengue outbreak has become endemic in over 100 nations with both North America, South America, Western Pacific regions and South-East Asia – of which India is a part, to be the most severely affected in the world.
As per media reports, national capital, Delhi has until now seen over 280 dengue cases with two deaths as well.
