Saal Greenstein syndrome: Saal Greenstein syndrome is a very rare autosomal recessive genetic disorder characterized by stunted growth, short limbs, microcephaly, and an anomalous cleavage of the anterior chamber of the eye. The disorder is similar to Robinow syndrome except for anterior chamber anomalies and, in one case, hydrocephalus.Iris dilator muscleAqueous humour: The aqueous humour is a transparent, gelatinous fluid similar to plasma, but containing low protein concentrations. It is secreted from the ciliary epithelium, a structure supporting the lens.Anterior segment mesenchymal dysgenesis: Anterior segment dysgenesis (ASD) is a failure of the normal development of the tissues of the anterior segment of the eye. It leads to anomalies in the structure of the mature anterior segment, associated with an increased risk of glaucoma and corneal opacity.Potocki–Shaffer syndrome: Potocki–Shaffer syndrome (PSS), also known as DEFECT11 syndrome or chromosome 11p11.2 deletion syndrome, is a rare contiguous gene syndrome that results from the microdeletion of section 11.Glaukomflecken: Glaukomflecken simply means glaucoma flecks.Dr Khairul Nazri Mohammad (Articles' Author), Waterford General Hospital, IRELAND It is anterior subcapsular or capsular opacity of the lens associated with focal epithelial infarct from past acute angle closure glaucoma.Intraocular pressureTrabecular meshwork: The trabecular meshwork is an area of tissue in the eye located around the base of the cornea, near the ciliary body, and is responsible for draining the aqueous humor from the eye via the anterior chamber (the chamber on the front of the eye covered by the cornea).Cataract surgeryGuiding Eyes for the Blind: Yorktown Heights, New YorkIntraoperative floppy iris syndromeCiliary body: The ciliary body is a part of the eye that includes the ciliary muscle, which controls the shape of the lens, and the ciliary epithelium, which produces the aqueous humor. The ciliary body is part of the uvea, the layer of tissue that delivers oxygen and nutrients to the eye tissues.A-scan ultrasound biometry: A-scan ultrasound biometry, commonly referred to as an A-scan, is routine type of diagnostic test used in ophthalmology.

Neuro-ophthalmologists initially complete a residency in either neurology or ophthalmology, then do a fellowship in the complementary field.Intraocular lymphoma: Intraocular lymphoma is a rare malignant form of eye cancer. Intraocular lymphoma may affect the eye secondarily from a metastasis from a non-ocular tumor or may arise within the eye primarily (primary intraocular lymphoma, PIOL).Vitreous membrane: The vitreous membrane (or hyaloid membrane or vitreous cortex) is a layer of collagen separating the vitreous humour from the rest of the eye. At least two parts have been identified anatomically.Iridodonesis: Iridodonesis () is the vibration or agitated motion of the iris with eye movement. This may be caused by lens subluxation, the incomplete or partial dislocation of the lens; or by aphakia, the absence of a lens.Lens Controller: A Lens Controller is device that controls motorized photographic lens functions such as zoom, focus, and iris or aperture.Kruegle, Herman (2007).Uveoparotitis: Uveoparotitis is a symptom of sarcoidosis. It describes a chronic inflammation of the parotid gland and uvea.Red eye (medicine)Corneal endothelium: The corneal endothelium is a single layer of cells on the inner surface of the cornea. It faces the chamber formed between the cornea and the iris.ParacentesisCorneal transplantationDiffuse unilateral subacute neuroretinitis: Diffuse unilateral subacute neuroretinitis (DUSN) is a rare condition that occurs in otherwise healthy, often young patients and is due to the presence of a subretinal nematode.Autorefractor: An autorefractor or automated refractor is a computer-controlled machine used during an eye examination to provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses. This is achieved by measuring how light is changed as it enters a person's eye.Imbert-Fick law: The Imbert-Fick "law" was invented by Hans Goldmann (1899–1991) to give his newly marketed tonometer (with the help of the Haag-Streit Company) a quasi-scientific basis; it is mentioned in the ophthalmic and optometric literature, but not in any books of physics. According to Goldmann,Goldmann H.Enucleation (surgery): As a general surgical technique, enucleation refers to the surgical removal of a mass without cutting into or dissecting it.Artificial tearsCoherence theory: In physics, coherence theory is the study of optical effects arising from partially coherent light and radio sources. Partially coherent sources are sources where the coherence time or coherence length are limited by bandwidth, by thermal noise, or by other effect.Pentaethylene glycol monododecyl etherLogMAR chart: A LogMAR chart comprises rows of letters and is used by ophthalmologists and vision scientists to estimate visual acuity. This chart was developed at the National Vision Research Institute of Australia in 1976, and is designed to enable a more accurate estimate of acuity as compared to other charts (e.LenticonusSustainability marketing myopia: Sustainability marketing myopia is a term used in sustainability marketing referring to a distortion stemming from the overlooking of socio-environmental attributes of a sustainable product or service at the expenses of customer benefits and values. The idea of sustainability marketing myopia is rooted into conventional marketing myopia theory, as well as green marketing myopia.Glaucoma surgeryBullous keratopathyAFR sensor: The AFR sensor is an air-fuel ratio sensor that is slowly replacing (or supplementing) the zirconia oxygen sensor (O2 sensor) in modern motor vehicles.Tadpole pupil: The eye is made up of the sclera, the iris, and the pupil, a black hole located at the center of the eye with the main function of allowing light to pass to the retina. Due to certain muscle spasms in the eye, the pupil can resemble a tadpole, which consists of a circular body, no arms or legs, and a tail.Trabeculoplasty: Trabeculoplasty is a laser treatment for glaucoma. It is done on an argon laser equipped slit lamp, using a Goldmann gonioscope lens mirror.CapsulotomyKramers' opacity law: Kramers' opacity law describes the opacity of a medium in terms of the ambient density and temperature, assuming that the opacity is dominated by bound-free absorption (the absorption of light during ionization of a bound electron) or free-free absorption (the absorption of light when scattering a free ion, also called bremsstrahlung).Phillips (1999), p.Congenital cataractAngle-resolved low-coherence interferometry: Angle-resolved low-coherence interferometry (a/LCI) is an emerging biomedical imaging technology which uses the properties of scattered light to measure the average size of cell structures, including cell nuclei. The technology shows promise as a clinical tool for in situ detection of dysplatic, or precancerous tissue.New Zealand rabbitLevobetaxololRobert Atkyns (topographer): Sir Robert Atkyns (1647–1711) was a topographer, antiquary, and Member of Parliament. He is best known for his county history, the Ancient and Present State of Gloucestershire.Eye injuryPars plana: The pars plana is part of the uvea, choroidea, one of the three layers that comprise the eye. As a part of the ciliary body, it is about 4 mm long, located near the point where the iris and sclera touch and is scalloped in appearance.Nephtheis fascicularisDilated fundus examination: Dilated fundus examination or dilated-pupil fundus examination (DFE) is a diagnostic procedure that employs the use of mydriatic eye drops (such as tropicamide) to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye.Exam Information Once the pupil is dilated, examiners use ophthalmoscopy (funduscopy) to view the eye's interior, allowing assessment of the retina, optic nerve head, blood vessels, and other features.Optimax: Optimax is a UK-based laser eye treatment specialist which has 38 locations nationwide. Optimax was established as one of the first private clinics to offer laser eye surgery.Outline of photography: The following outline is provided as an overview of and topical guide to photography:Fuchs heterochromic iridocyclitis: Fuchs heterochromic iridocyclitis (FHI) is a chronic unilateral uveitis appearing with the triad of heterochromia, predisposition to cataract and glaucoma, and keratitic precipitates on the posterior corneal surface.
