Conjunctival concretions are generally asymptomatic.Common symptoms include eye discomfort, eye irritation, and foreign body sensation. Sometimes, the larger, harder or multiple concretions make the rubbing off of the superficial layers of the conjunctiva or eyelids to cause conjunctival abrasion, especially prominent when blinking.
An abrasion is a partial thickness wound caused by damage to the skin. [1] It can be superficial involving only the epidermis to deep, involving the deep dermis. Abrasions usually involve minimal bleeding. [ 2 ]
Eye injury by impact of small plastic body. Based on the injury to the eyewall (outer fibrous coat of the eye consisting of cornea and sclera) Closed globe injury: the eye globe is intact, but the seven rings of the eye have been classically described as affected by blunt trauma. Types include contusion and lamellar laceration
Corneal abrasion is a scratch to the surface of the cornea of the eye. [3] Symptoms include pain, redness, light sensitivity, and a feeling like a foreign body is in the eye. [1] Most people recover completely within three days. [1] Most cases are due to minor trauma to the eye such as that which can occur with contact lens use or from ...
Facial trauma, also called maxillofacial trauma, is any physical trauma to the face.Facial trauma can involve soft tissue injuries such as burns, lacerations and bruises, or fractures of the facial bones such as nasal fractures and fractures of the jaw, as well as trauma such as eye injuries.
Entropion, severe dry eye and trichiasis (inturning of eyelashes) may cause ulceration of the peripheral cornea. Immune-mediated eye disease can cause ulcers at the border of the cornea and sclera . These include Rheumatoid arthritis, rosacea, systemic sclerosis which lead to a special type of corneal ulcer called Mooren's ulcer.
With the eye generally profusely watering, the type of tears being produced have little adhesive property. Water or saline eye drops tend therefore to be ineffective. Rather a 'better quality' of tear is required with higher 'wetting ability' (i.e. greater amount of glycoproteins) and so artificial tears (e.g. viscotears) are applied frequently.
A coloboma (from the Greek κολόβωμα, meaning "defect") [1] is a hole in one of the structures of the eye, such as the iris, retina, choroid, or optic disc.The hole is present from birth and can be caused when a gap called the choroid fissure, which is present during early stages of prenatal development, fails to close up completely before a child is born.
