Subconjunctival bleeding occurs in about 2% of newborns following a vaginal delivery. The blood accumulates between the conjunctiva and the episclera. Diagnosis is generally based on the appearance of the conjunctiva. [2] The condition is relatively common, [4] and both sexes are affected equally. Spontaneous bleeding occurs more commonly over ...
A subconjunctival hemorrhage can often occur without any obvious cause or harm to the eye. A strong enough sneeze or cough can cause a blood vessel in the eye to burst. Hyphema is a result of blunt or penetrating trauma to the orbit that increases intraocular pressure, causing tears in the vessels of the ciliary body and iris .
subconjunctival hemorrhage [1] – a sometimes dramatic, but usually harmless, bleeding underneath the conjunctiva most often from spontaneous rupture of the small, fragile blood vessels, commonly from a cough or sneeze
The resulting loose, excess conjunctiva may mechanically irritate the eye and disrupt the tear film and its outflow, leading to dry eye and excess tearing. [2] A correlation may also exist between inflammation in the eye and conjunctivochalasis, though it is unclear whether this correlation is causal.
A petechia (/ p ɪ ˈ t iː k i ə /; [1] pl.: petechiae) is a small red or purple spot (≤4 mm in diameter) that can appear on the skin, conjunctiva, retina, and mucous membranes which is caused by haemorrhage of capillaries.

In the anatomy of the eye, the conjunctiva (pl.: conjunctivae) is a thin mucous membrane that lines the inside of the eyelids and covers the sclera (the white of the eye). [1] It is composed of non-keratinized, stratified squamous epithelium with goblet cells , stratified columnar epithelium and stratified cuboidal epithelium (depending on the ...
