Since the year of 2009, research indicates that computer use has taken the place of radio as the No. 2 media activity. The increased use of computers has reflected on the development of visual discomfort and related symptoms occurring in relation to computer use. (more…)
Eso deviation often present as a constant esotropia occurring in infancy or early childhood. Fusional divergence is used to correct for an eso deviation, however our innate divergence amplitude are typically weak. Measuring only 6 – 8 prism diopter. It is likely that our weak divergence amplitude contribute to the poor control of eso deviation. (more…)
Exo-deviation is an outward deviation which can be divided into exophoria and exotropia. Exodeviation are quite common, and they are not necessarily. A small intermittent exotropia is normal in most newborns, as 70 % of normal newborns have a transient exodeviation that resolves by 2 to 4 months of age. Another type of exo deviation that is considered normal is a small exophoria (<10pd). (more…)
A healthy retina is necessary for good vision. For diabetic retinopathy patient, at first they may notice no changes to the vision. But over time, diabetic retinopathy can get worse and cause vision loss. It usually affects both eyes. (more…)

Cataract is usually a gradual lost of vision is defined as loss of vision which had come gradually over the course of weeks or months rather than minutes, hours or few days. Generally, there are a few factors that may contribute to gradual vision loss such as cataract, glaucoma, age-related macular degeneration and etc. (more…)
The vitreous humor is a clear, gelatinous substance consisting of collagen and sodium hyaluronate that fills the eyeball between the retina and the lens, making up about 2/3 of the volume of the eye. It is firmly attached anteriorly at the peripheral retina and posteriorly at the optic nerve. To know more about floaters, we should first know about our eye anatomy so that it would be easier to understand the facts. (more…)
