The presence of dark circles or bags around the eyes shows the bad health of a person. This may be caused due to stress or strain, disease, fatigue, medication, hereditary or due to anemia. These dark circles appearing just under the eyes are blood vessels which are seen through the skin. This mainly happens because the thickness of the skin below the eye is very thin. Sometimes these dark circles may appear as hereditary. A bluish tint occurs when blood passes through large veins. Since the skin is very transparent, the circles may appear much darker. The dark circles can also be caused due to the deficiency of iron or due to poor diet. The presence of dark circles under the eyes also indicates the deficiency of oxygen in the tissues of the body. Sometimes excessive exhaustion may also cause the skin to pale, leading to dark circles. Aging also makes the skin to become translucent and thus making it darker. Sometimes pigmentation also leads to the formation of dark circles because melanin is produced near the eyes.

There is no perfect treatment for dark circles. So it is found that it cannot be completely cured. There are some homemade solutions to make this dark circles to fade. One such method is to drink plenty of water and fluids so that to improve circulation and to eliminate toxins. Avoid consuming whole foods, fruits, vegetables. Also avoid the habit smoking, consumption of alcohol and drinks which are caffeinated. Use of tea bags or slices of potato or slices of raw cucumber may reduce dark circles. They are put on the closed eyes for about 20 mins and then they are washed off by using cold water. Doing this process for a week may lighten the dark circles appearing under the eyes. The dark circles can also be treated by improving blood circulation by pressuring under the eyes. In some cases washed cloth immersed in rosemary tea is placed on the eyes as treatment against dark circles.

Infective and Bacterial Conjunctivitis

INFECTIVE CONJUNCTIVITIS

Infective conjunctivitis, i.e., inflammation of the conjunctiva caused by microorganisms is the commonest variety. This is in spite of the fact that the conjunctiva has been provided with natural protective mechanisms in the form of low temperature due to exposure to air, physical protection by lids, flushing action of tears, antibacterial activity_of lysozymes and humoral protection by the tear immunoglobulins.
BACTERIAL CONJUNCTIVITIS
There has occurred a relative decrease in the incidence of bacterial conjunctivitis in general and those caused by gonococcus and corynebacterium diphtheriae in particular. However, in developing countries it still continues to be the commonest type of conjunctivitis. It can occur as sporadic cases and as epidemics. Outbreaks of bacterial conjunctivitis epidemics are quite frequent during monsoon season.
Etiology
A. Predisposing factors for bacterial conjunctivitis, especially epidemic forms, are flies, poor hygienic conditions, hot dry climate, poor sanitation and dirty habits cause of bacterial conjunctivitis and blepharoconjunctivitis.

  • Staphylococcus epidermidis is an innocuous flora of lid and conjunctiva. Rarely it can also produce blepharoconjunctivitis.
  • Streptococcus pneumoniae (pneumococcus) produces acute conjunctivitis usually associated with petechial subconjunctival haemorrhages. The disease has a self-limiting course of 9-10 days.
  • Streptococcus pyogenes (haemolyticus) is virulent and usually produces pseudomembranous conjunctivitis.
  • Haemophilus influenzae (aegyptius, Koch-Weeks bacillus). It classically causes epidemics of mucopurulent conjunctivitis, known as ‘redeye’ especially in semitropical countries.
  • Moraxella lacunate (Morax-Axenfeld bacillus) is most common cause of angular conjunctivitis and angular blepharo conjunctivitis.
  • Pseudomonas pyocyanea is a virulent organsism. It readily invades the cornea.
  • Neisseria meningitidis (meningococcus) may produce mucopurulent conjunctivitis.
  • Corymebacterium diphtheriae causes acute membranous conjunctivitis. Such infections are rare now- a-days.

C. Mode of infection. Conjunctiva may get infected from three sources, viz, exogenous, local surrounding structures and endogenous, by following modes :

  • 1. Exogenous infections may spread: (i) directly through close contact, as air-borne infections or as water-borne infections; (ii) through vector transmission (e.g. flies); or (iii) through material transfer such as infected fingers of doctors, nurses, common towels, handkerchiefs, and infected tonometers.
  • 2. Local spread may occur from neighbouring structures such as infected lacrimal sac, lids, and nasopharynx. In addition to these, a change in the character of relatively innocuous organisms present in the conjunctival sac itself may cause infections.
  • 3. Endogenous infections may occur very rarely through blood

Inflammations of Conjunctiva classifications

Inflammation of the conjunctiva (conjunctivitis) is classically defined as conjunctival hyperaemia associated with a discharge which may be watery, mucoid, mucopurulent or purulent.
Etiological classification

  • 2. Allergic conjunctivitis.
  • 3. Irritative conjunctivitis.
  • 5. Traumatic conjunctivitis.
  • 6. Keratoconjunctivitis of unknown etiology.

Clinical classification
Depending upon clinical presentation, conjunctivitis can be classified as follows:

  • 1. Acute catarrhal or mucopurulent conjunctivitis.
  • 2. Acute purulent conjunctivitis
  • 3. Serous conjunctivitis
  • 4. Chronic simple conjunctivitis
  • 5. Angular conjunctivitis .
  • 6. Membranous conjunctivitis
  • 7. Pseudomembranous conjunctivitis
  • 8. Papillary conjunctivitis
  • 9. Follicular conjunctivitis
  • 10.Ophthalmia neonatorum
  • 11. Granulomatous conjunctivitis
  • 12.Ulcerative conjunctivitis
  • 13.Cicatrising conjunctivitis

To describe different types of conjunctivitis, a mixed approach has been adopted, i.e. some varieties of conjunctivitis are described by their etiological names and others by their clinical names. Only common varieties of clinical interest are described here.
