Corneal Pachymetry
Measurement of the thickness of the CORNEA.
Corneal Topography
The measurement of curvature and shape of the anterior surface of the cornea using techniques such as keratometry, keratoscopy, photokeratoscopy, profile photography, computer-assisted image processing and videokeratography. This measurement is often applied in the fitting of contact lenses and in diagnosing corneal diseases or corneal changes including keratoconus, which occur after keratotomy and keratoplasty.
Cornea
The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)
Diagnostic Techniques, Ophthalmological
Methods and procedures for the diagnosis of diseases of the eye or of vision disorders.
Keratomileusis, Laser In Situ
A surgical procedure to correct MYOPIA by CORNEAL STROMA subtraction. It involves the use of a microkeratome to make a lamellar dissection of the CORNEA creating a flap with intact CORNEAL EPITHELIUM. After the flap is lifted, the underlying midstroma is reshaped with an EXCIMER LASER and the flap is returned to its original position.
Keratoconus
A noninflammatory, usually bilateral protrusion of the cornea, the apex being displaced downward and nasally. It occurs most commonly in females at about puberty. The cause is unknown but hereditary factors may play a role. The -conus refers to the cone shape of the corneal protrusion. (From Dorland, 27th ed)
Corneal Edema
An excessive amount of fluid in the cornea due to damage of the epithelium or endothelium causing decreased visual acuity.
Lasers, Excimer
Gas lasers with excited dimers (i.e., excimers) as the active medium. The most commonly used are rare gas monohalides (e.g., argon fluoride, xenon chloride). Their principal emission wavelengths are in the ultraviolet range and depend on the monohalide used (e.g., 193 nm for ArF, 308 nm for Xe Cl). These lasers are operated in pulsed and Q-switched modes and used in photoablative decomposition involving actual removal of tissue. (UMDNS, 2005)
Tomography, Optical Coherence
An imaging method using LASERS that is used for mapping subsurface structure. When a reflective site in the sample is at the same optical path length (coherence) as the reference mirror, the detector observes interference fringes.
Encyclopedias as Topic
Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
Refractive Surgical Procedures
Surgical procedures employed to correct REFRACTIVE ERRORS such as MYOPIA; HYPEROPIA; or ASTIGMATISM. These may involve altering the curvature of the CORNEA; removal or replacement of the CRYSTALLINE LENS; or modification of the SCLERA to change the axial length of the eye.
Ocular Hypertension
A condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.
Intraocular Pressure
The pressure of the fluids in the eye.
Glaucoma, Open-Angle
Glaucoma in which the angle of the anterior chamber is open and the trabecular meshwork does not encroach on the base of the iris.
Tonometry, Ocular
Measurement of ocular tension (INTRAOCULAR PRESSURE) with a tonometer. (Cline, et al., Dictionary of Visual Science, 4th ed)
Periodicals as Topic
A publication issued at stated, more or less regular, intervals.
Access to Information
Individual's rights to obtain and use information collected or generated by others.
Journal Impact Factor
A quantitative measure of the frequency on average with which articles in a journal have been cited in a given period of time.
Publishing
"The business or profession of the commercial production and issuance of literature" (Webster's 3d). It includes the publisher, publication processes, editing and editors. Production may be by conventional printing methods or by electronic publishing.
Observer Variation
The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).
Reproducibility of Results
The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
Pathology
A specialty concerned with the nature and cause of disease as expressed by changes in cellular or tissue structure and function caused by the disease process.
Privacy
The state of being free from intrusion or disturbance in one's private life or affairs. (Random House Unabridged Dictionary, 2d ed, 1993)
Confidentiality
The privacy of information and its protection against unauthorized disclosure.
Computer Security
Protective measures against unauthorized access to or interference with computer operating systems, telecommunications, or data structures, especially the modification, deletion, destruction, or release of data in computers. It includes methods of forestalling interference by computer viruses or so-called computer hackers aiming to compromise stored data.
Informed Consent

The protection of genetic information about an individual, family, or population group, from unauthorized disclosure.
Internet
A loose confederation of computer communication networks around the world. The networks that make up the Internet are connected through several backbone networks. The Internet grew out of the US Government ARPAnet project and was designed to facilitate information exchange.
Keratectomy, Subepithelial, Laser-Assisted
A surgical technique to correct REFRACTIVE ERRORS of the EYE, such as MYOPIA and ASTIGMATISM. In this method, a flap of CORNEAL EPITHELIUM is created by exposure of the area to dilute alcohol. The flap is lifted and then replaced after laser ablation of the subepithelial CORNEA.
Photorefractive Keratectomy
A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.
Myopia
A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.
Astigmatism
Unequal curvature of the refractive surfaces of the eye. Thus a point source of light cannot be brought to a point focus on the retina but is spread over a more or less diffuse area. This results from the radius of curvature in one plane being longer or shorter than the radius at right angles to it. (Dorland, 27th ed)
Hyperopia
A refractive error in which rays of light entering the eye parallel to the optic axis are brought to a focus behind the retina, as a result of the eyeball being too short from front to back. It is also called farsightedness because the near point is more distant than it is in emmetropia with an equal amplitude of accommodation. (Dorland, 27th ed)
Refractive Errors
Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus.
Migraine Disorders
A class of disabling primary headache disorders, characterized by recurrent unilateral pulsatile headaches. The two major subtypes are common migraine (without aura) and classic migraine (with aura or neurological symptoms). (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)
Migraine without Aura
Recurrent unilateral pulsatile headaches, not preceded or accompanied by an aura, in attacks lasting 4-72 hours. It is characterized by PAIN of moderate to severe intensity; aggravated by physical activity; and associated with NAUSEA and / or PHOTOPHOBIA and PHONOPHOBIA. (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)
Eye
The organ of sight constituting a pair of globular organs made up of a three-layered roughly spherical structure specialized for receiving and responding to light.
Glaucoma
An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (Dictionary of Visual Science, 4th ed)
Glaucoma, Angle-Closure
A form of glaucoma in which the intraocular pressure increases because the angle of the anterior chamber is blocked and the aqueous humor cannot drain from the anterior chamber.
Eye Diseases
Diseases affecting the eye.
Vision Disorders
Visual impairments limiting one or more of the basic functions of the eye: visual acuity, dark adaptation, color vision, or peripheral vision. These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132).
Optic Nerve
The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.
Endothelium, Corneal
Single layer of large flattened cells covering the surface of the cornea.
Lenses, Intraocular
Artificial implanted lenses.
Ophthalmology
A surgical specialty concerned with the structure and function of the eye and the medical and surgical treatment of its defects and diseases.
Strabismus
Misalignment of the visual axes of the eyes. In comitant strabismus the degree of ocular misalignment does not vary with the direction of gaze. In noncomitant strabismus the degree of misalignment varies depending on direction of gaze or which eye is fixating on the target. (Miller, Walsh & Hoyt's Clinical Neuro-Ophthalmology, 4th ed, p641)
Cataract
Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)
Cataract Extraction
The removal of a cataractous CRYSTALLINE LENS from the eye.
Ophthalmologic Surgical Procedures
Surgery performed on the eye or any of its parts.

Central corneal thickness considered an index of corneal hydration of the UVB irradiated rabbit cornea as influenced by UVB absorber. (1/42)

UVB radiation from sunlight induces an acute corneal inflammation, photokeratitis, accompanied by changes in corneal hydration. We employed a method of ultrasonic pachymetry for daily examination of central corneal thickness as an index of corneal hydration of the rabbit cornea repeatedly irradiated by UVB radiation (312 nm, daily dose of 0.25 J/cm(2) during three or four days) as influenced by UVB absorber (actinoquinol combined with hyaluronic acid) dropped on the ocular surface during irradiation. One day after the third irradiation procedure the animals were sacrificed and corneas examined immuno-histochemically for peroxynitrite formation, a marker of oxidative damage, the antioxidant aldehyde dehydrogenase 3A1 and endothelial nitric oxide synthase, an enzyme generated nitric oxide. Results show that UV absorber combined with hyaluronic acid protected the cornea against UVB-induced changes in corneal thickness and microscopical disturbances to the cornea (both seen after buffered saline application) until the fourth experimental day. These UVB doses are equivalent to a daily exposure of 2.5 hrs of the human cornea to solar UVB radiation for three consecutive days. It is suggested that actinoquinol/ hyaluronic acid drops might be helpful for the human eye in the defence against photooxidative and other oxidative processes.  (+info)

A short-term in vivo experimental model for Fuchs endothelial corneal dystrophy. (5/42)

PURPOSE: We evaluated the in vivo functionality of a corneal endothelium tissue-engineered using corneal endothelial cells from human patients with Fuchs endothelial corneal dystrophy (FECD). METHODS: A total of 15 healthy cats underwent full-thickness corneal transplantation. All transplants were of xenogeneic human origin and all grafts but two were tissue-engineered. In seven animals the graft corneal endothelium was tissue-engineered using cultured corneal endothelial cells from humans with FECD (TE-FECD). Two control animals were grafted with an endothelium engineered using cultured endothelial cells from normal eye bank corneas (TE-normal). Two controls received a native full-thickness corneal transplant, and four other controls were grafted with the stromal carrier only (without endothelial cells). Outcome parameters included graft transparency (0, opaque to 4, clear), pachymetry, optical coherence tomography, endothelial cell morphometry, transmission electron microscopy (TEM), and immunostaining of function-related proteins. RESULTS: Seven days after transplantation, 6 of 7 TE-FECD grafts, all TE-normal grafts, and all normal native grafts were clear (transparency score >3), while all carriers-only grafts were opaque (score <1). The mean pachymetry was 772 +/- 102 mum for TE-FECD, 524 +/- 11 mum for TE-normal, 555 +/- 48 for normal native, and 1188 +/- 223 mum for carriers only. TEM showed subendothelial loose fibrillar material deposition in all TE-FECD grafts. The TE endothelium expressed Na(+)-K(+)/ATPase and Na(+)/HCO3(-). CONCLUSIONS: Restoration of transparency and corneal thickness demonstrated that the TE-FECD grafts were functional in vivo. This novel FECD seven-day living model suggests a potential role for tissue engineering leading to FECD cell rehabilitation.  (+info)

Corneal pachymetry - WikipediaCorneal pachymetry - Wikipedia
Corneal pachymetry is the process of measuring the thickness of the cornea. A pachymeter is a medical device used to measure the thickness of the eyes cornea. It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses. It can be done using either ultrasonic or optical methods . The contact methods, such as ultrasound and optical such as confocal microscopy (CONFOSCAN), or noncontact methods such as optical biometry with a single Scheimpflug camera (such as SIRIUS or PENTACAM), or a Dual Scheimpflug camera (such as GALILEI), or Optical Coherence Tomography (OCT, such as Visante) and online Optical Coherence Pachymetry (OCP, such as ORBSCAN). Corneal Pachymetry is essential prior to a refractive surgery procedure for ensuring sufficient corneal thickness to prevent abnormal bulging of the cornea, a side effect known as ectasia. The instrument used for this ...

Corneal Pachymetry - Medical Clinical Policy Bulletins | AetnaCorneal Pachymetry - Medical Clinical Policy Bulletins | Aetna
Corneal pachymetry is a non-invasive ultrasonic technique for measuring corneal thickness, and has been used primarily in the evaluation of persons with corneal diseases and in the assessment of persons at risk for glaucoma. Ultrasonic corneal pachymetry is performed by placing an ultrasonic probe on the central cornea, after the cornea has been anesthetized with a topical anesthetic. A technician can operate the pachymeter and it normally takes less than 30 seconds per eye to complete measurements.. The Ocular Hypertension Treatment Study (Kass et al, 2002; Gordon et al, 2002), a prospective randomized controlled clinical trial of glaucoma treatment in persons with elevated intra-ocular pressure (IOP) greater than or equal to 24 mm Hg, found central corneal thickness a statistically significant predictor of development of glaucoma. Corneal thickness was measured only after the study was initiated, and was not used to guide therapy. For the enrolled patients, the Ocular Hypertension Treatment ...

Purpose: To assess reproducibility of central corneal thickness (CCT) measurement by means of ultrasonic pachymetry.. Methods: Fifty one volunteers underwent three sessions of CCT measurements, each consisting of three CCT measurements, performed by each of three different observers. Intra- and interobserver reproducibility was calculated by means of intraclass correlation coefficient (ICC). The expected range of variability between two independent evaluations was calculated using scatter plots of each test-retest difference against their mean. The standard deviation of the mean differences in the test-retest scores was used to describe the differences in the score spread.. Results: The ICC ranges of the intra- and interobserver evaluations were 0.95-0.97 and 0.89-0.95 respectively; the expected variability was ⩽±1% and ⩽± 2% respectively (95% confidence interval).. Conclusions: The measurement of CCT by means of ultrasonic pachymetry is highly reproducible.. ...

The distribution of the CCT values is shown in Figure 1. The mean (SD), median, skewness, and kurtosis of CCT distribution was 530.9 (31.5) μm (range 380-627), 529.0 μm, 0.08, and 0.32, respectively, which suggest a normal distribution. The distributions of CCT for age categories are presented in Table 1. In univariate analysis, a thicker CCT was correlated significantly with a younger age (P , 0.001), higher IOP (P , 0.001), and longer AL (P = 0.003); however, CCT was not associated significantly with ACD (P = 0.087, Table 2). According to the regression line, CCT decreased by 4.0 μm for every decade of life (95% confidence intervals [CI] 2.4-5.5 μm), increased by 2.73 μm for every 1 mm Hg increase in the IOP (95% CI 2.10-3.36 mm Hg), and increased by 2.84 μm for every mm increase in the AL (95% CI 0.98-4.71 μm). When CCTs of male and female subjects were compared, the average CCT in men was 5.8 μm more than that in women (P = 0.001, Table 3). The average CCT in subjects with ...

Results: The mean central corneal thickness was 537±42 µm (OCT), 535±43 µm (OCP), 552±40 µm (US 20) and 551±34 µm (US 50). The reproducibility was 3.3 µm (OCT), 3.1 µm (OCP), 2.6 µm (US 20) and 1.8 µm (US 50). The mean epithelial thickness was 68±9 µm (OCT) and 54±3 µm (US 50) with a reproducibility of 5.9 µm (OCT) and 1.9 µm (US 50). Although the correlations coefficients for the measurements of the corneal thickness were between 0.97 and 0,99 (P,0,001), the mean difference between optical and acoustic methods was 20 µm (P,0,001). The limits of agreement (±2SD) revealed maximum values of ±41 µm (7.6 ...

Assessment of central corneal thickness and corneal endothelial morphology using ultrasound pachymetry, non-contact specular...Assessment of central corneal thickness and corneal endothelial morphology using ultrasound pachymetry, non-contact specular...
Reproducible and repeatable objective means to evaluate corneal endothelial morphology and CCT are vital, in both clinical and research settings. Assessment of the endothelium is crucial to determine the suitability of donor corneas, to monitor the outcome of anterior segment procedures, such as cataract surgery, and when evaluating the safety of new intraocular or corneal surgical procedures and intraocular lenses [32, 33]. Thus, assessment and validation of newly developed measurement techniques is essential to determine which techniques can be used interchangeably.. The results of this study indicate that the intra-observer repeatability of ECD, CV, and CCT measurements using z-ring CS4 were not significantly different (p ≥ 0.05). Also, there were no statistically significant differences in intra-observer repeatability for observer 1 of ECD, CV, and CCT measurements with SP-2000P and USP (CCT only). These results indicate a high reliability of repeat testing for ECD, CV, and CCT ...

Collagen Cross-Linking for Keratoconus/Ectasia With and Without Intacs - Tabular View - ClinicalTrials.govCollagen Cross-Linking for Keratoconus/Ectasia With and Without Intacs - Tabular View - ClinicalTrials.gov
In this study we will attempt to determine whether Collagen Cross Linking alone, one combined with insertion of INTACS is the most effective treatment for patients with progressive keratoconus in patients who have progressive disease.. These treatments have been widely used outside of the United States for the treatment of progressive keratoconus. Corneal Collagen Cross linking was recently approved in the United States for the treatment of progressive keratoconus. We will attempt to study 600 patients total. 300 patients will be assigned to cross linking only while another 300 will be assigned to cross linking and INTACS. Once adequate number of study subjects have been recruited data will be analyzed to determine which treatment is more effective. The following parameters from Topography, OCT and Tomography will be studied(these are Max K(pentacam) Kvalue(Tomey Topography)I-Svalue(Tomey Topography Astigmatism(Tomey Topography) and Min OCT(corneal pachymetry) any one of these metrics that ...

In their letter to the editor, De Roo and colleagues1 present results from complementary experiments. Inclusion of an extended range of analytes and an additional cohort of pseudophakic controls (Edemapsph), composed of eyes diagnosed with graft failure or pseudophakic bullous keratopathy, allow for a more detailed analysis. The authors confirm the results from our study with respect to elevated aqueous MCP-1 expression in pseudophakic FECD eyes and demonstrate increased expression of aqueous IL-8 after cataract surgery.1 Their results describe increased TGF-β2 levels in phakic FECD patients compared with phakic (cataract) controls and increased TGF-β2 levels in pseudophakic FECD patients compared with pseudophakic controls (Edemapsph).1 Moreover, they find increased TGF-β3 expression in the aqueous humor of phakic FECD eyes compared with all three other groups.1 ...

Blue Sclera and Tendon Rupture | The Journal of the American Osteopathic AssociationBlue Sclera and Tendon Rupture | The Journal of the American Osteopathic Association
A 53-year-old man presented for an ocular health evaluation. Early in his childhood, the patient received a diagnosis of osteogenesis imperfecta (OI) type I. His medical history included 27 bone fractures before age 12 years, multiple tendon ruptures, osteoporosis, a mechanical aortic valve replacement, and recurrent corneal erosions. The examination revealed a blue-gray appearance of the sclera in both eyes (image A). Results of a corneal pachymetry measurement revealed decreased corneal thickness. A recent magnetic resonance image revealed a complete rupture of his quadriceps tendon distally (image B, arrow). The diagnosis was corneal thinning secondary to OI type I. ...

Corneal pachymetry is a useful practice: it consists in measuring the corneal depth in order to monitor the cornea guttata and corneal edema status.. In the initial phase it can be treated with a therapy consisting in hyperosmotic agents that draw excess water out of the cornea, making it possible to improve vision, most likely only for a period of time.Later on, it is best to substitute the damages endothelium via an endothelium corneal transplant with the DMEK or DSAEK technique.. ...

LASIK may result in following the path of problem maker rather than the bringing relief to the eye. In a small percentage of cases, it is observed that LASIK has caused temporary nearsightedness and farsightedness. Also there are patients who have reported problems of Astigmatism after the surgery.. These problems may lead to regression of the eye. That is, it may hamper the ability of the eye to read and cause discomfort while reading sentences for which one needs to move the eye. These problems are treatable and may be resolved by healing with time.. ...

This work shows that three-dimensional images from MPLSM of endogenous tissue fluorescence can effectively distinguish between normal, precancerous, and cancerous epithelial tissues. The high-resolution capability of MPLSM enabled the identification of three morphologic features (nuclear density ratio, keratin, and epithelial thickness), which showed statistically significant differences between normal and both precancerous and cancerous tissues. Moreover, statistically significant differences were observed in the keratin thickness of dysplasia and both types of SCCs and in the epithelial thickness of dysplasia and CIS. The lack of statistically significant differences in the epithelial thickness of dysplasia and SCCs may be because the imaging depth was limited by signal attenuation in the SCCs, thus underestimating the epithelial thickness in these samples. The statistically significant morphologic changes that accompany precancer and cancer development in the MPSLM images ( Table 1) are ...
