Do you feel a tickling sensation in your eyes? Is it turning weirdly pink? Well, it could surely be a sign of eye infection. However, it is the doctor who makes the final call. Infections can pop up in numerous ways. It can show up in the eyelids, the cornea or the clear layer sheltering the outside of your eye and the conjunctiva. Understanding how your eye feels and keeping tabs on the symptoms is what matters most. Here’s revealing a couple of symptoms you can take note of:

  1. Itchy eyes.
  2. Discomfort and pain in the organ.
  3. Eyes turn extremely sensitive to bright light.
  4. The persistent feeling that there is something piled up in the eye.
  5. Painful lumps popping up at the base of the eyelashes.
  6. Teary eyes all the time.
  7. The eyes burn.
  8. The eyelids appear highly sensitive and tender when touched.

Inflammation can shoot up and you could also put up with blurry vision. Eye infections could pop up as consequence of harmful microorganisms like bacteria, virus, and fungi attacking the eyeball and its surrounding area. It is imperative to visit a doctor for an immediate diagnosis. Bear in mind, there are various types of eye infections. Understanding the cause by tracking the symptoms is what plays a pivotal role.

Types of eye infections and what are the causes?

  1. Conjunctivitis – Also known as ‘Pink Eye’, it is undoubtedly one of the most common and contagious infections known to all and sundry. The conjunctiva is the prime most moist area surrounding the interiors of the eye and the outer part swells up and become inflamed. Little did you know that this transparent layer is a storehouse of blood vessels. When a bacterial or viral attack strikes, these vessels dilate causing the grisliest bloodshot eyes. The pink eye could also be caused by allergens like animal dander, pollen, and dust.
  2. Fungal keratitis – The name clearly suggests that it is a fungal eye infection. This infection is caused by Fusarium fungi, found in most organic matters. It invades the eyes causing injury and inflammation.
  3. Viral keratitis – Viral eye infections including pink eye is more common than you think. The condition shoots up when exposed to Herpes simplex virus.
  4. Trachoma – Trachoma is clearly wide-spread in under-developed regions and the consequences are as serious as absolute blindness. Inner eyelids are targeted to this form of infection and the layer begins to scar. It ultimately casts a ruining impact on the cornea, leading to permanent blindness. The infection can be spread by flies in unsanitary environments.
  5. Acanthamoeba keratitis – The condition mostly targets contact lens wearers. Parasites invade the organ, paving way for a severe infection called Acanthamoeba keratitis.
  6. Endophthalmitis – It is bacteria that penetrate the interiors of the eye. Blindness is an obvious consequence if not treated early. The infection can spring up due to an existing injury and can also appear as an offshoot of cataract surgery.

What are the complications one can put up with?

  1. When an infection strikes the interiors of the eye, particularly the tear glans, it can lead to inflammation. It could also put a bar on the eye’s tear drainage system.
  2. Such infections are mostly the underlying cause of corneal ulcer. It must be treated prompt or else could lead to vision loss.

It is worth understanding the complications of conjunctivitis as it one of the most common infections dealt with.

  • There are redness and itching of the eyes.
  • A mucous like transparent discharge is always in a flow if it is caused due to the virus. However, when targeted with bacterial conjunctivitis, the discharge appears dense and white, green or yellow in color.
  • There forms a crust on the top of the eyelids.
  • The constant irritating feeling as if there is sand in the eyes.

Complications of keratitis and other frontal infections include:

  • Itching and pain in the eye.
  • Always feel as if there’s a foreign body present in the organ.
  • The eyes could be completely red or minor red lines popping out in the white of the eye.
  • Swollen eyelids.
  • Eyes turn highly sensitive to bright light.
  • Formation of crusts on the lids.
  • Yellow discharge, particularly after waking up in the morning.
  • Teary eyes.
  • Involuntary blinking (blepharospasm).

What’s strange is that diseases that affect the optic nerve, retina and blood vessels cause little to no pain at all. The symptoms involve deteriorating vision. The consequences cannot be reversed. However, it could certainly be put to a stop. Floaters are always found on the inside of the eye. If, however, there is a sudden increase in these floaters, you must get it checked right-away. Ignoring eye infection is not a wise call. Serious damages could involve absolute damage to the retina. It also includes scars and ulcers in the cornea that causes a hindrance to clear vision. Cataclysmic infections like syphilis can spike up chances of glaucoma. In a nutshell, get the condition treated before it turns into something grave.
