India, the worst hit country during the second wave of coronavirus, have facing many post covid challenges like black fungus or vision loss, which led people worried.
Now, in order to address query Dr Vanuli Bajpai, consultant – ophthalmology, HCMCT at Manipal Hospitals Delhi explain about about long-term visual recovery and explains why some patients can also have vision loss because of Covid.
According to the words of Dr. Bajpai: “While the eyes are not often affected during or after a Covid-19 infection, there are symptoms like conjunctivitis that are seen among Covid-19 patients. Very few patients may have long-term eye damage. Also in few cases, the retina and retina vessels have been impacted, leading to long-term diminution of vision."
Doctor also said “Due to the blockage of the retinal veins there lead to visual loss and needs treatment. The long-term visual recovery in these cases is variable, ranging from complete recovery to significant visual loss.”
Most matter of concern is mucormycosis, or black fungus. Rhino-Orbital-Cerebral Mucormycosis (ROCM) occurring among Covid patients, especially those with diabetes mellitus, who were on treatment with corticosteroid therapy. ROCM is a severe and fatal fungal infection. This is an infection of the nose and sinuses with fungus, which can spread to the orbit (bony cage in which the eye is housed) and its structures.
The patients recovering from Covid, especially if they have diabetes, need to be aware of the common symptoms of mucormycosis like stuffiness in the nose, discharge from the nose, foul smell, bleeding from the nose, swelling around eyes or face, blurry vision, double vision, change in colour of skin around eyes/ nose/ face, pain around nose/eyes/face. Patient need to contact their Physician, ENT specialist or Ophthalmologist as needed for further treatment.
