What are the characteristics of acanthamoeba keratitis?
This pus-producing condition is very painful. It is a common source of infection in people who wear soft or rigid contact lenses. It can be found in tap water, soil, and swimming pools
How does acanthameoba keratites eat and move?
Organisms in the genus Acanthamoeba typically move by the use of extensions of their cellular membrane referred to as pseudopods. These pseudopods can also be used to grab food (typically bacteria, which are significantly smaller than amoebas) and pull it through the cellular membrane by a process referred to as phagocytosis.
What sicknesses can amoeba cause?
Some amoeba do cause human diseases the most common would be amoebic dysentery, but there are also other amoeba that can infect the eye (Acanthamoeba - Eye Parasite) and there are probably more.

What is acanthamoeba keratitis?
Acanthamoeba eye infections in contact lens wearers are rare but serious, and they often start because of improper lens handling and poor hygiene. To avoid Acanthamoeba keratitis, contact lens wearers should follow lens wearing and cleaning instructions from both manufacturers and eye doctors very closely. Proper contact lens care greatly reduces the risk of all contact lens-related eye infections, including those caused by Acanthamoeba. Wow I'm 16 and I know all about this....lol....

Corneal ulcers and infections?
DefinitionThe cornea is the transparent area at the front of the eyeball. A corneal ulcer is an erosion or open sore in the outer layer of the cornea. It is associated with infection.See also: Corneal injuryAlternative NamesBacterial keratitis; Fungal keratitis; Acanthamoeba keratitis; Herpes simplex keratitisCauses, incidence, and risk factorsCorneal ulcers are most commonly caused by an infection with bacteria, viruses, fungi, or parasite. Other causes include:Abrasions (scratches)Foreign bodies in the eyeInadequate eyelid closureSeverely dry eyesSevere allergic eye diseaseVarious inflammatory disordersContact lens wear, especially soft contact lenses worn overnight, may cause a corneal ulcer. Herpes simplex keratitis is a serious viral infection. It may cause repeated attacks that are triggered by stress, exposure to sunlight, or any condition that impairs the immune system.Fungal keratitis can occur after a corneal injury involving plant material, or in immunosuppressed people. Acanthamoeba keratitis occurs in contact lens users, especially those who attempt to make their own homemade cleaning solutions.Risk factors are dry eyes, severe allergies, history of inflammatory disorders, contact lens wear, immunosuppression, trauma, and generalized infection.SymptomsEye burning, itching and dischargeEye painEye rednessImpaired visionSensitivity to light (photophobia)Watery eyesWhite patch on the corneaSigns and testsExamination of scrapings from the ulcerFluorescein stain of the corneaKeratometry (measurement of the cornea)Pupillary reflex responseRefraction testSlit-lamp examinationTear testVisual acuityBlood tests to check for inflammatory disorders may also be needed.TreatmentTreating corneal ulcers and infections depends on the cause. They should be treated as soon as possible to prevent further injury to the cornea. Patients usually start treatment with an antibiotic that is effective against many bacteria. More specific antibiotic, antiviral, or antifungal eye drops are prescribed as soon as the cause of the ulcer has been identified.Corticosteroid eye drops may be used to reduce inflammation in certain conditions. Severe ulcers may need to be treated with corneal transplantation.Expectations (prognosis)Untreated, a corneal ulcer or infection can permanently damage the cornea. Untreated corneal ulcers may also perforate the eye (cause holes), resulting in spread of the infection inside, increasing the risk of permanent visual problems.ComplicationsLoss of the eyeSevere vision lossScars on the cornearCalling your health care providerCall your health care provider if you develop impaired vision, severe light sensitivity, or eye pain.PreventionPrompt, early attention by an ophthalmologist for an eye infection may prevent ulcers from forming. Wash hands and pay very close attention to cleanliness while handling contact lenses. Avoid wearing contact lenses overnight.ReferencesButler FK. The eye in the wilderness. In: Auerbach PS, ed.
