Eye sample may be cultured to test the sensitivity of the bacteria. This test helps in diagnosing the cause of eye infection. The goal is to see if there is an aerobic infection present in the eye fluid (conjunctival fluid). For this test, a cotton swab is used to collect the fluid present in the eye. Your healthcare provider will pass a moistened swab two times or more over the lower conjunctiva.
When microorganisms like bacteria, virus or fungi invade eyeball or surrounding parts of eyeballs the eye infection occurs. Eye infections can be categorized according to the part of the eye that is getting infected for example conjunctivitis is an inflammation of the conjunctiva, inflammation of the eyelid (blepharitis), inflammation of cornea (keratitis), the liquid inside the eye (vitritis), or it can also be categorized according to the type of organism that is causing the infection for example Ocular histoplasmosis syndrome (OHS) caused by fungus (the condition is also called chorioretinitis). The symptoms of an eye infection include itchy eyes, pain, discomfort, burning sensation in the eyes, small painful lump at the base of your eyelashes or under your eyelid, pink color in the white of your eyes, crusty lashes and lids, discharge from one or both eyes that are yellow, green, or clear, swollen, red, or purple eyelids, etc.
Bacteria are the single-celled micro-organisms that can live within the soil, in the ocean and also inside the human gut. They have a number of shapes such as spirals, rods, and spheres etc. Some bacteria can cause illness to the human body and some other plays a major role in the overall functioning of our ecosystem.
Aerobic bacteria are the bacteria which can survive in the presence of oxygen only. In the absence of oxygen, aerobic bacteria cannot survive and can die. Some of the aerobic bacteria are Mycobacterium tuberculosis, Nocardia, Staphylococcus aureus, Enterococcus faecalis etc.
This test may be recommended to you if you experience certain symptoms like the burning of the eyes, itchy eyes, sticky thick mucus-like discharge from the eyes, redness, slight blurring of the vision, etc. This test may be specially performed to check if the infection is due to aerobic bacteria or not. This test is also recommended to plan the treatment according to the type of bacteria. The test is also recommended to check the effectiveness of the treatment given.
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your C/S Aerobic Eye Sample. Your doctor will give specific instructions depending on your condition on how to prepare for C/S Aerobic Eye Sample.
No specific preparation is required for this test.
The normal test results may vary depending on age, health history, medical condition, etc.
If your test results show negative it means there is no growth of aerobic bacteria.
If your test results show positive it may indicate that you may have an aerobic bacterial infection in your eye.
If you get abnormal test results, consult your doctor immediately with your lab test reports.
