Primary congenital glaucoma is a rare eye condition that is present at birth or develops early in childhood. It occurs due to improper drainage of the eye's fluids, which leads to increased pressure inside the eye, known as intraocular pressure. This elevated pressure can damage the optic nerve which will result in permanent vision loss.
Around 6% of infants have congenital nasolacrimal duct obstruction, or dacryostenosis, usually experiencing a persistent watery eye even when not crying. If a secondary infection occurs (dacryocystitis), purulent (yellow / green) discharge may be present. Most cases resolve spontaneously, with antibiotics reserved only if conjunctivitis occurs.
Adenoviral keratoconjunctivitis, also known as epidemic keratoconjunctivitis, is a contagious eye infection, a type of adenovirus disease caused by adenoviruses. [1] It typically presents as a conjunctivitis with a sudden onset of a painful red eye, watery discharge and feeling that something is in the eye. [3]
Other associated signs may include pre-auricular lymph node swelling and contact with another person with a red eye. [7] Eye pain may be present if the cornea is also involved. [7] Its symptoms include excessive watering and itching. The discharge in viral conjunctivitis is usually (but not always) watery in nature. [7]
A red eye is an eye that appears red due to illness or injury. It is usually injection and prominence of the superficial blood vessels of the conjunctiva, which may be caused by disorders of these or adjacent structures. Conjunctivitis and subconjunctival hemorrhage are two of the less serious but more common causes.
Dacryocystitis is an infection of the lacrimal sac, secondary to obstruction of the nasolacrimal duct at the junction of the lacrimal sac. [1] The term derives from Greek dákryon 'tear' cysta 'sac' and -itis 'inflammation'. [2]
Orbital cellulitis is inflammation of eye tissues behind the orbital septum. It is most commonly caused by an acute spread of infection into the eye socket from either the adjacent sinuses or through the blood. It may also occur after trauma. When it affects the rear of the eye, it is known as retro-orbital cellulitis.
The symptoms of fungal keratitis typically emerge over 5-10 days and present with a painful eye, blurred vision, and redness of eye. [1] There is increased sensitivity to light, and excessive tears or discharge. [1] The symptoms are markedly less as compared to a similar bacterial ulcer. [1]
