Keratoconus

LAMELLAR KERATOPLASTY VERSUS INTRACORNEAL RING SEGMENTS IN TREATING MODERATE KERATOCONUS Mohammed Alsaied Alnaimy*, Abdelmonem Alsyed Abou-sharkh, Mahmoud Nasr Al-deeb and Ayman Mohammed Abdelrahman Ophthalmology Department, Faculty of Medicine, Zagazig University, Zagazig, Egypt. *Corresponding author: Mohammed Alsaied Alnaimy, Mobile: 01226043131 E mail:moh_alnaimy@hotmail.com ABSTRACT Background: Keratoconus can cause gradual distortion of vision due to progressive myopia and irregular astigmatism. keratoconus is classified into four stages. The treatment is stage specific starting from glasses or hard contact lenses in the very early stages passing to intra corneal…

Interstitial Keratitis, or its abbreviation “IK” for many ophthalmologists, is an inflammation of the cornea. “Keratitis” is the term for inflammation of the cornea, while “interstitial” refers to the area between cells. In this case, it refers to the stroma—the area between the epithelium and endothelium of the cornea. Other names include “nonulcerative keratitis”, which describes the inflammation as not breaking through the epithelial layer of the cornea via sores, “syphilitic keratitis,”…

Introduction Eye enucleation is surgery to permanently remove the eyeball (globe). The space that remains (socket) after the eyeball is removed will be filled with an artificial eyeball (implant). Muscle tissue will be sewn onto the implant to keep the implant in place and to give it some movement. The natural eyeball may need to be removed because of: Injury. Diabetes. Tumors. Eye disease such as glaucoma. Inflammation or infection of the inner eye (endophthalmitis). A painful, blind eye.…

Keratoconus Keratoconus is a disease that results in thinning of the central zone of the cornea, the front surface of the eye. During further observation it is found that the normal eye pressure causes the round shape of the cornea to distort and an irregular cone-like bulge develops which results in significant visual impairment. The quality of vision seems poor which also occurs primarily from irregular astigmatism and distortion that results in the image focusing at multiple points instead of…

I have had many life changing experiences but there is one that has impacted me the most. It is my experience with Keratoconus. One day during 2016 I woke up and my vision was on my right eye was covered by a something white and cloudy. It turned out to be a scar in my eye caused by Keratoconus. Keratoconus is an eye disease a person is born with that affects the cornea by making it slope instead of being round, and for the most part a cornea transplant is needed as the disease further…

within the end chains of the collagen fibrils and this natural cross-linkage of collagen explains why corneal ectasia often progresses most rapidly in adolescence or early adulthood but tends to be stable in patients after middle-age (Ashwin and MaDonnell, 2010). Human studies of UV-induced corneal cross-linking began in 2003 in Dresden, and early results were promising. The initial study involved patients with rapidly progressing keratoconus and all of them stopped progressing after…

Contact lenses for hard-to-fit eyes Have you ever had trouble when it comes to wearing contact lenses or been told that you simply can’t wear them? Don’t give up just yet as it may just be a case of having what’s known as “hard-to-fit” eyes. This doesn’t mean you can’t wear contact lenses; you just need to know your options. Want to find out a little more? Then read on as we discuss reasons for having hard-to-fit eyes along with a number of possible contact lenses for hard-to-fit eyes. There…

has resettled. For people with a connective tissue disorder, the collagen in their cells can be compared to a balloon filled with slush or ice, depending on the severity of the condition. This balloon has no ability to stretch or bounce back. Eye Conditions Caused by Compromised Collagen The ineffective collagen in the eyes can result in a number of eye conditions and problems. Some are simply irritating, such as blue sclera and light sensitivity, while others may be life-changing, such as: …

Interestingly, astigmatism has very few natural causes. In fact, the underlying cause of astigmatism is unknown. It is a hereditary vision issue that often occurs from birth. Astigmatism can also increase and decrease as you age. Chalazion is a benign nodule located in the upper or lower eyelid that has been associated with astigmatism. Scarring or an eye disease termed keratoconus may also cause astigmatism as well. However, the vision condition is often associated with myopia and hyperopia. …
