You have heard about different bacteria, fungi and parasites that somehow attack human body and are responsible for various diseases.
To make you more aware, let me tell you that countless critters too do exist that attack the interior part or core of the eyes. Hence, by striking the eyes they become the source of various grossest diseases. These are just a few of them.
This disease tends to be caused by worm Onchocerca volvulus. As the name suggest, the infected flies that live near rivers get transmitted and infect the eyes.
After coming into the contact of skin, the parasite drops larvae. And for this, medications are available but it is safe to use insect repellent either. Travellers have more chance of getting infected.
Amoeba Keratitis is a vision-threatening parasitic ailment that is caused by a pathogen called Acanthamoeba Keratitis. Even non-lens wearers do also get influenced but the people who wear contact lens need to be careful more as they are much prone towards it.
Acanthamoeba has its species mostly in tap water, sewage and lakes. Its one of the life cycle phases called trophozoites may invade the human body through nasal passage or eyes.
People getting infected show several signs and symptoms such as pain and discomfort.
Kissing bugs or triatomine bugs cause Chagas disease. This disease is not a new one and as per the reports, it is in existence since 9000 years.
The parasites simply enter into a bite wound and cause eyelids to swell down. Sometimes in early phases the symptom gets unnoticed.
The critters can get originate from mud, wall cracks, straw and building substances. The initial stage of disease can be treated but the lateral stage tends to become a major problem.
Myiasis is a kind of sickness that gets spread by bot flies parasite Hypoderma tarandi that affects humans and especially women. This is discovered from 520 B.C.
The Myiasis larvae can often cause vision defects, retinal detachment and glaucoma. It also leaves scary hooks on the skin that prove to be very discomforting. Vitrectomy or laser larva removal is the treatment for this disease.
The host through which this disease spreads is a domestic cat and parasite it carries - Toxoplasma gondii. The transmission starts with the contact with the cat feces.
The cysts dropped by toxoplasma causes vision to get blurred. And if the infection is not cured at right time then it may damage retina. Keep yourself safe next time you clear the litter stuff as sometimes it becomes gruelling to know whether the cat is infected or not.
