Whats fuchs's corneal dystrophy?

Whats fuchs's corneal dystrophy?

Fuchs: Fuchs is a disease of the inner layer of the cornea. In some pts, this layer fails over time and the cornea can become swollen. When the cornea is swollen, the patient can experience vision loss. Additionally, some patient's with Fuchs' get a plaque or membrane in their central corneal causing vision decline. In these instances, surgery such as DSEK (partial corneal transplantation) is helpful ...Read more

Can corneal abrasion cause astigmatism?

Can corneal abrasion cause astigmatism?

No: Unless they cause corneal scarring (can lead to irregular astigmatism), but typically they heal ok if the eye health is good and lids are in place. ...Read more

What is cornea, fovea, macula?

What is cornea, fovea, macula?

Eye parts: The cornea is the window at the front of the eye which focus light and allows it to enter the eye. Contact lenses rest on the cornea. The macular is the central retinal area of sharper vision and the fovea is the very center of the macula with the sharpest of all vision. ...Read more

Vitrectomy eye surgery if macula hole retinal detachment?

Vitrectomy eye surgery if macula hole retinal detachment?

Yes: Most common procedure to repair a retinal detachment resulting from a macular hole is a vitrectomy (remove the fluids from the back of the eyeball), replace it with a gas, and position the patient face down for some period of time (sometimes weeks) to allow the hole to close and the detachment to resolve. Most macular holes do not cause a detached retina, but many require a similar operation. ...Read more

Will lazer surgery/intraocular lens fix strabismus/cross eyed?

Will  lazer surgery/intraocular lens fix strabismus/cross eyed?

Not usually: Laser eye or implant surgery will correct your prescription but strabismus will likely persist. Muscle surgery may be needed. On the other hand, if glasses or contacts correct your eye misalignment, laser or implant surgery may fix both problems. ...Read more

Progressive macular pucker 20/30 vision, distortion & glaucoma. Visual fIeld good,nerve damage 30-45%.Would vitrectomy cause glaucoma to progress?

Possible: Vitrectomy and glaucoma may have an association. It is suspected that glaucoma occurs more often in patients who have had vitrectomy and subsequent cataract surgery. An ongoing clinical trial is aimed to answer this question with more clarity. PROVE Study. http://www.aaojournal.org/article/S0161-6420(14)00344-3/references AND https://clinicaltrials.gov/ct2/show/NCT01162356 ...Read more

What are corneal opacities?

What are corneal opacities?

Corneal opacities: Corneal opacities can be cause by anything that injuries the cornea or causes scarring of the cornea. Foreign bodies in the eye are common causes, late effects of severe trauma, various infections, certain congenital or genetic conditions. The image below shows you what one kind of opacity looks like. Do a google search under 'images' for corneal opacity and you will see lots. ...Read more

Corneal abrasion with bandage contact lens how will cornea heal?

Corneal abrasion with bandage contact lens how will cornea heal?

Fine: Years ago the treatment for an abrasion was a pressure patch. But in recent years ophthalmologists have switched from patching to using a bandage contact lens with antibiotic and possibly a mild steroid to decrease the inflammation. Continue your care with the same ophthalmologist. ...Read more

Can eye surgery correct myopia with astigmatism?

Can eye surgery correct myopia with astigmatism?

Astigmatism correctn: Absolutely. The vast majority of corneal refractive surgery, i.e. Lasik or surface ablation/prk, is for just that. Most people wearing glasses for distance vision are myopic, and most of them have some amount of astigmatism as well. Today's lasers can correct a very high proportion of your myopia and your astigmatism. Some lasik surgeons give free educational appointments or seminars. ...Read more

What is myopic retinal detachment?

What is myopic retinal detachment?

See below: Myopic eyes are longer (axial length) and thus the retina is thinner and potentially more at risk for developing retinal tears and holes that can ultimately lead to retinal detachment. ...Read more

Are corneal opacities the same as corneal dystrophy?

Are corneal opacities the same as corneal dystrophy?

No: Anything causing a deposit anywhere on the cornea is termed an opacity - most due to a specific injury such as a foreign body or ulcer of the cornea after healing. Corneal dystrophy is more generalized throughout the cornea affecting one or another layer, some inherited and others like the condition fuch's, which is acquired. See your corneal specialist ophthalmologist to sort this out. ...Read more

Could lasik lead to keratoconus?

Could lasik lead to keratoconus?

Technically, no.: But doing lasik on a patient with keratoconus could be disastrous. Additionally, ablating too much corneal tissue during the lasik procedure could result in a corneal ectasia. This type of thinning can lead to abnormal corneal curvature, distortion of vision and a condition resembling, in some ways, keratoconus. Best to discuss with your lasik doc. ...Read more

Micropsia: Yes, it can if the macular pucker is severe enough. Micropsia is a condition in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema,macular degeneration, and more ...Read more

Corneal collagen cross-linking for keratoconus, what to do?

Corneal collagen cross-linking for keratoconus, what to do?

Crosslinking: Corneal collagen crosslinking for keratoconus is an effective treatment, as it stops the progression of keratoconus, and in most patients, will result in improvement in corneal shape and improvement in vision. Crosslinking is available throughout the world, and in the us, at more than 100 sites. Cxlusa.Com provides a directory of us locations. ...Read more

Who should have prk (photorefractive keratectomy) over lasik?

Lasik and PRK: Various diagnostic test should be done in order to see if a person is the right candidate for either lasik or prk. Depending on a person's corneal thickness and corneal shape, these should be taken into consideration when deciding which procedure to do. ...Read more

Could lasik surgery correct astigmatism?

Could lasik surgery correct astigmatism?

LASIK: Typically yes. The majority of astigmatism can be corrected with refractive surgery. However, in patients with severe astigmatism or with irregular corneas inducing astigmatism, it is not recommended these patient undergo surgery. A detailed examination with an eye surgeon specializing in vision correction surgery such as LASIK/PRK is the best next step to determine if you are a good candidate. ...Read more

Could lasik surgery cause eye floaters?

Could lasik surgery cause eye floaters?

Unlikely from LASIK: Floaters are caused by clumping or debris in the vitreous jelly of the eye. Most near sighted individuals and inidviduals over 50 see floaters at some point in their life. Any type of trauma can exacerbate floaters and if the lasik surgery was 'traumatic' the floaters in the jelly may be noticed or worsened. ...Read more
