Ocular Hypertension: What Causes High Eye Pressure?

Ocular hypertension also known as high IOP (intraocular pressure) is a medical condition where the pressure inside your eyes is higher than the ‘normal range’ in the population. While you might not feel or notice any symptoms however in 10% - 18% of unchecked ocular hypertensives, this condition can lead to glaucoma. Read the article below to learn the causes, risks, treatments and ways to manage ocular hypertension.

What is Myopia?

Myopia is one of the most common refractive errors, causing nearby objects to appear clear and objects in the distance to appear blurry. For example, you may find it easy to focus on close objects, such as reading a book, but find it difficult to see road signs at a distance. This happens when the size of the eye is too large, causing light rays to focus in front of the retina as opposed to on it.

What is Astigmatism?

Alongside myopia, hyperopia and presbyopia, astigmatism is one of the most common refractive errors that affect vision. It is an eye condition caused by the curvature being different in different planes for the cornea, lens or both. The British Contact Lens Association (BCLA) defines astigmatism as a ‘focusing disorder of the eye that distorts vision’. If not corrected in time, the quality of vision can get worse. Learn in this detailed guide what causes astigmatism, its various types, symptoms, diagnosis, treatment options and more.
