    A (VAST)IN Saga

    Vascular endothelial growth factor (VEGF)-A is a key mediator of angiogenesis. The discovery of VEGF-A, like many other major discoveries in medicine, happened partly by observations and partly by chance. Napoleone Ferrara and his team were working on a population of non-hormone-secreting cells from the anterior pituitary of cows. (1) One day Ferrara mixed some isolates from cultures of follicular cells with endothelial cells. Ferrara was surprised to see the rapidly proliferating endothelial cells started rapidly. Ferrara understood that the pituitary cells were secreting an angiogenic protein. With this observation, Ferrara worked on the isolation and cloning of this angiogenic protein. In 1989, Napoleone Ferrara and Hazel at Genentech laboratory were the first to isolate and clone vascular endothelial growth factor (VEGF). Ferrara recalls, “I worked on the isolation of VEGF in my spare time during my first six months to a year at Genentech. Once we cloned VEGF in 1989, the company b

    Anatomy of Retina

    The retina is the innermost of the three coats of the eye. This layer is responsible for converting relevant information from the image of the external environment into neural impulses that are transmitted to the brain. Broadly retina consists of two primary layers: an inner neurosensory retina and retinal pigment epithelium (RPE). 1 ? Sensory retina develops from the inner layer of the neuroectoderm, whereas RPE is derived from the outer layer of the neuroectoderm. The RPE is continuous anteriorly with the pigment epithelium of the ciliary body. Sensory retina extends from the optic disc to ora serrata, where it is continuous with non-pigmented ciliary epithelium.1 Between the neural retina and RPE, there is a potential space known as subretinal space. The adhesion between neural retina and RPE is relatively weak. The neural retina is firmly attached at its anterior termination, the ora serrata, and at the margins of the optic nerve head. The ora serrata is located 4-6 mm behind cilia

    Anatomy of Uvea

    Uvea is the middle vascular coat of the eyeball. From anterior to posterior, the uvea or uveal tract can be divided into three parts- Iris, Ciliary body, and choroid. The name “uvea” has originated from the Latin word grape. Why a grape? If the stem is removed from a grape, the hole looks like the pupil and the grape the eyeball. Iris : Iris is the anterior-most part of the uveal tract. It is a thin and circular structure which forms a diaphragm like structure in front of the crystalline lens. The word “iris” has originated from a Greek word. In Greek mythology, the iris is the name of the Greek goddess of the rainbow. The diaphragm formed by the iris contains a central aperture known as the pupil. The location of the pupil is not exactly central, its little nasal to the center. The pupil determines the amount of light entering the eye. The normal size of the pupillary aperture is 3-4 mm. Details on the pupil will be discussed in chapter "Pupil". Iris is attached to the middle of the a

    Word Root : Origin of Ophthalmic Terms

    The study of the origin of word is known as etymology. Most of the ophthalmic terminology is derived from Greek and Latin words. Most probably Hippocrates (460-370 BC) was the first to use specific ophthalmic terms that we are still using nowadays. He has been credited for using the terms like amblyopia, hippus, nystagmus & phthisis. Similarly, terms like canthus, exophthalmos, glaucoma, and leukoma are thought o be the contribution of Aristotle (384-322 BC). It was Galen (13 l-201 AD) who used the terms like chalazion, chemosis, iris, mydriasis, pterygium, strabismus, and trichiasis. Here in this section, I have compiled some terms of ophthalmology with their root of origin. Canthus = Greek word “kanthas” = angle Levator palpebrae superioris = In Latin, “levator” = to lift, “palpebrae” = an eyelid, superioris = upper Caruncle = Latin word means flesh. Plica semilunaris = Latin word “Plicare” = to fold, “semilunaris” = half moon. Tarsus = Greek word means flat, Ancient greeks used to c

    Mnemonics in Ophthalmology

    In this section, we tried to gather all the mnemonics of ophthalmology, which we think will be of great benefit for our readers especially the students of Ophthalmology. However, the database is now in its infancy. So, if you have any mnemonics on ophthalmology, told by your teacher, friends, please send it to me at drparthopratim@gmail.com Remember Keratoconus with the help of CONES Central scarring & Fleischer ring Oil drop reflex / Oedema (hydrops) Nerves prominent Excessive bulging of lower lid on downgaze (Munson’s sign) Striae (Vogt’s) Remember Iridocorneal Endothelial Syndrome with ICE Iris Naevus Chandler Syndrome Essential Iris Atrophy Remember Behcet's Disease with the help of ORAL UPSET Occlusive periphlebitis Retinitis Anterior uveitis Leakage from retinal vessels Ulceration (aphthous/genital) Pustules after skin trauma (Pathergy test) Scratching leaves lines (dermatographism) Erythema nodosum Thrombophlebitis Remember posterior scleritis with POST SCLER Proptosis Ophthalmo

    Acute Retinal Necrosis

    Acute retinal necrosis was first described in Japan by Urayama and colleagues who described six otherwise healthy patients, presented with panuveitis and retinal arteritis developing retinal detachment. At that point of time, this entity was known in the Japanese literature as “Kirisawa uveitis”1.Young and Bird first used the term “bilateral acute retinal necrosis” in 1978 2. In 1982 Culbertson and associates 3 first reported the possible involvement of a herpes group virus as the causative agent of acute retinal necrosis syndrome after histopathology and electron microscopy evaluation of an enucleated eye. The Executive Committee of the American Uveitis Society 4 de?ned the disease by its clinical characteristics and disease course in 1994. Epidemiology: Acute retinal necrosis generally affects healthy, immunocompetent individuals regardless of sex or race. However, Fisher et al found little male preponderance in their study 5. The disease affects typically young adults. Bimodal age d

    Serpiginous Choroiditis: An Update

    The word “serpiginous” is an adjective which means “with a wavy or indented margin”. The serpiginous choroiditis shows the similar wavy or amoeboid like lesions in choroid as a result of inflammation of unknown aetiology. The serpiginous choroiditis may be defined as a chronic, progressive, usually bilateral, recurrent in?ammatory condition which affects the choroid, choriocapillaries and retinal pigment epithelium. This clinical entity was first reported by Junius in 1932 who termed it as “peripapillary retinochoroiditis”. Thereafter this clinical entity has passed through various nomenclatures by various authors (Table 1). The term “serpiginous choroidopathy” was coined by Gass in 1987.

    Anatomy of Sclera

    The term sclera is derived from Greek word scleros meaning "hard".Sclera is an opaque, elastic, and resilient tissue of the eye. It can be compared with an incomplete shell comprising approximately 90% (five-sixths) of the outer coat of the eye. Anteriorly it begins at the limbus and terminates at the optic nerve canal posteriorly. The primary function of the sclera is to protect the eye and maintain the shape of the eye ball. Amazing Fact: Human beings are the only primates with white sclera Embryologically like corneal stroma and endothelium, sclera originates from mesoderm. The human sclera is white in colour. This white appearance is because of the scattering of all wavelengths of light by dense irregular bundles of collagen in sclera. In children, a bluish hue is observed because of the extremely thin sclera which allows the visibility of underlying choroid. In older age the sclera may appear slightly yellowish because of the deposition of fat. Thickness of sclera: Sclera is thick

    Anatomy of Anterior Chamber

    Anterior chamber is an angular space bounded anteriorly by the posterior (inner) surface of the cornea and posteriorly by the anterior surface of the iris and a part of cilliary body. Boundary of anterior chamber: Anteriorly Posteriorly Inner surface of the cornea At periphery, trabecular meshwork Lens, Anterior surface of the iris and Anterior face of the ciliary body Anterior chamber is 3 mm deep and it contains 0.25 ml of the aqueous humour. Anterior chamber depth is shallower in the hypermetropic eye than the myopic eye. It is also shallower in children and in older people. Anterior Chamber at a glance Volume: 220 µL. Chamber Volume decreases by 0.11 µL/year life Depth: 3.15mm (2.6- 4.4mm) Chamber depth decreases by 0.01mm/year of life. Chamber depth is shallower in the hypermetropic than myopic .Chamber deepens by 0.06mm for each diopter of myopia. Chamber depth is slightly diminished during accommodation, partly by increased lens curvature & partly by forward translocation of the
