Retinitis Pigmentosa Treatment or Cure Possible?

In degenerative conditions like retinitis pigmentosa, the cells (mainly rods) which absorb light and convert the light energy into electrical energy gradually die. The resultant loss of vision is irreversible. For now, there is no treatment available for retinitis pigmentosa. Scientist all over the world are working on solutions to enhance vision and prevent blindness in such cases. There seems to be a breakthrough in retinitis pigmentosa research now.

Laser Peripheral Iridotomy Procedure and Its Role in Glaucoma Management

Peripheral iridotomy is an office procedure performed with lasers which involves making a hole in the periphery of the iris to create a communication between posterior chamber (the space between lens and iris) and anterior chamber (the space between iris and cornea). It is mainly used in narrow angle glaucoma and some other conditions (e.g.: plateau iris) where the aqueous needs to flow freely from posterior chamber to anterior chamber. Lasers Used for Iridotomy There [...]

Can Presbyopia Be Managed Without Glasses?

Presbyopia is a condition of middle-age in which near vision becomes poor. It is usually corrected with glasses. The newer treatments are aimed at getting rid of glasses. Corneal inlays are tiny implants which are inserted into the cornea changing its shape and refractive power. Raindrop inlay is one such example. A gel-like device that looks like a miniature contact lens, the Raindrop inlay is smaller than the eye of a needle, and is placed [...]

Eggs Are Good for Macular and Visual Function

Lutein, zeaxanthin and meso-xanthin are important catotenoid pigments found in the macula which is the most important part of retina. Macula subserves the central vision. The above pigments are not made in our body and we must consume dietary products which contain them. Yellow of egg is an important source of lutein and zeaxanthin pigments. The macula, which is a core tissue of retina, is mainly constituted by three carotenoid pigments; namely lutein (L), zeaxanthin [...]

The topical anesthetics like paracaine and proparacaine when instilled after a corneal abrasion provides relief from pain immediately but it is not prescribed for further use to prevent some possible complications. A review of some recent studies suggests that it may not be true. Via The dogma: Patients with corneal abrasions should not be discharged home with topical anesthetic agents because [...]

What Causes Bulging Eyes

The most common cause of bulging eyes (proptosis/exophthalmos) is Grave’s disease, an autoimmune disease. It causes enlargement of the muscles which are responsible for eye movements. Additionally, the vascular congestion and swelling around the eyes cause pressure effects and pushes the eyeballs forward. Grave's eye disease is 3 to 10 times more common in females than in males. The mean age of appearance of Grave's thyroid disease is about 41-42 years. This disease is usually self-limited [...]

What Does LASIK Laser Eye Surgery Feel Like?

George Chesterton describes how he underwent LASIK surgery by Professor Dan Reinstein at London Vision Clinic. One eye was treated for myopia (far-sightedness) and the other eye was treated for presbyopia.
