or under estimations of real hazards people may face. For example, it is unlikely a person is going to accidentally pour an entire bottle of mascara into their eye. Also, the Draize test where this occurs is done on rabbits. Rabbits have “thinner corneas and insufficient tear ducts” meaning their eyes could not wash away irritants as effectively as a human eye. Their eyes are structured differently and are much more sensitive than ours, making the comparison invalid (Dickinson). Peter Singer…

however the percentage is a lot higher in those who suffer with RA. It causes a gritty feeling in the eye or the eye may even water. Occasionally the cornea can be effected in relation to ‘dry eye syndrome’, this can lead to inflammation, followed by scarring (NRAS, 2017). This is because RA affects collagen and this is what the sclera and cornea are made up of. Other diseases related to inflammation of the eye are Scleritis, uveitis, and Retinal Vascular Occlusion these are all caused by…

Humans rely on the use of five senses to understand the world around us; taste, touch, sight, hearing and smell. One of the most used in our daily life is sight. Just take a moment and think about every thing you have seen since you got up this morning. Although you might not know it there is a complex proses of perceiving being done by your eyes each time you open them.

Angle-closure glaucoma is defined as an obstruction of the flow of aqueous humor in the eye due to the iris and trabecular meshwork being too close together which creates a closed angle where 270 degrees or more of the angle is occluded.1 Occlusion of the angle causes the intraocular pressure (IOP) to elevate. Optic nerve damage can occur if IOP is greater than 40 mmHg and permanent vision loss can occur if an individual's IOP is greater than 60 mmHg.2 The incidence of angle-closure glaucoma…

Osteogenesis Imperfect is also known as the, “Brittle Bone Disease”. This is an extremely rare disease with less than twenty thousand cases a year.

small amount actually reaches the intraocular tissues because most gets washed away with the tear fluid or gets absorbed systemically through the nasolacrimal duct system[9]. The remarkably low penetration of drug across the epithelial surface of cornea to the vitreous chambers is another issue[10]. Intravitreal injection is the currently preferred route of delivery to treat diseases of the posterior segment because it directly delivers drugs to the eye lesions. It is generally safe but…
