These weakened arteries can also sometimes begin to bulge in some areas. This bulge is known as an aneurysm. If the bulge ruptures, it can cause life-threatening bleeding at the heart or sight-threatening bleeding in the eye. High blood pressure also places stress on the organs of the body...

They are caused by rupture of blood vessel walls or microaneurysms, and their increased presence is a clear sign of the use of a damaged retina. They have very different shapes, ranging from round red dots with sharp margins, to spotting bleeding, to bleeding in the form of fire. When ...
It has been suggested that these haemorrhages occur when the transmural stresses accompanying the rapid and marked intraocular pressure changes occuring when the eye is opened during cataract surgery, are sufficient to cause rupture of a choroidal blood vessel. Ischaemic optic atrophy is an occasional...
Small glands lining the edge of the eyelids produce oil that helps lubricate the surface of the eye (meibomian glands). When one of these glands becomes blocked, oil backs up inside the gland and forms a bump in the eyelid. If the gland ruptures, the oily materials can irritate the surro...
Mutations in the ZNF469 gene cause brittle cornea syndrome (BCS), an autosomal recessive disorder associated with extreme corneal thinning and a high risk of corneal rupture.45 Multiple studies by various research groups identified significant enrichment of potentially pathogenic ZNF469 alleles in KC pa...
ophthalmia), characterised by excessive tears and mucous and swelling of the eyelids, which can take a variety of forms, such as pain and dryness, ulcerations, sleeplessness, as well as ruptures and inflammation (Loeb Celsus VI.6.B–E).70 The symptoms described by Celsus resemble those in...

Pupillary Defect(RAPD) indicates significant obstruction of the sensory pathway and is extremely useful in stratifying ofinjury. It cannot be caused bycataractorvitreous haemorrhagebut instead indicates more serious pathology (e.g.retinal detachment, posteriorglobe ruptureor optic nerve injury) (Fig. 2...
