First report of Thelazia sp. from a captive Oriental white stork (Ciconia boyciana) in Japan. (1/1498)

Nematodes of the genus Thelazia were recovered from the cornea and inferior conjunctival sac of an immature Oriental white stork (Ciconia boyciana). The bird hatched and reared at the Toyooka Oriental White Stork Breeding Center, Hyogo Prefecture, Japan, but died of chlamydiosis. There were neither gross nor histopathologic ophthalmic lesions. The eye worm from a bird is believed to be first reported in Japan. As regarding reintroduction plan for the Oriental white stork, control measures for prevent further infection with the eye worm will be needed.  (+info)

Epithelial hyperproliferation and transglutaminase 1 gene expression in Stevens-Johnson syndrome conjunctiva. (2/1498)

In Stevens-Johnson syndrome, pathological keratinization of the ordinarily nonkeratinized corneal and conjunctival mucosal epithelia results in severe visual loss. We examined conjunctiva covering cornea in five eyes in the chronic cicatricial phase of Stevens-Johnson syndrome. Normal conjunctiva from five age-matched individuals was studied also. The number of epithelial cells in Stevens-Johnson syndrome conjunctiva that were immunoreactive with a monoclonal antibody, Ki-67, to a nuclear antigen found only in proliferating cells was greater than normal (93.8+/-19.8 cells above 100 basal cells versus 12.8+/-0.5 cells above 100 basal cells; P = 0.009). In addition, although clinical inflammation was mild, massive lymphocytic infiltration was seen in the substantia propria of conjunctiva covering cornea. In situ hybridization documented transglutaminase 1 (keratinocyte transglutaminase) mRNA in suprabasal cells of the abnormally thickened conjunctival epithelium in all Stevens-Johnson syndrome patients. In contrast, no message was detected in normal conjunctival or corneal epithelia. Transglutaminase 1 is expressed during the terminal differentiation of keratinocytes where it helps synthesize cornified cell envelopes. We speculate that in Stevens-Johnson syndrome, epithelial hyperproliferation, and transglutaminase 1 gene expression lead to the pathological keratinization of ocular surface mucosal epithelia.  (+info)

Effect of intracarotid prostaglandin E1 on regional cerebral blood flow in man. (3/1498)

The effect of prostaglandin E1 on regional cerebral blood flow (rCBF) was studied with the intra-arterial 133Xe method in ten awake patients under local anesthesia. Measurements were taken from 16 areas of a hemisphere in seven patients, from 35 areas of a hemisphere in two patients and from 256 areas of a hemisphere in one patient. The prostaglandin was dissolved from the crystalline state without the aid of alcohol. It was given intracarotidly as a constant infusion at a rate of 5 ng per kilogram per minute for five minutes before the measurement and continued during the measurement. In every patient a mild increase in blood flow during the prostaglandin infusion was seen. The flow increase took place in all parts of the hemisphere. It averaged 11.2% (p less than 0.01). During the infusion, the skin supplied by the internal carotid artery and the conjunctiva on the infused side became red and sometimes swollen. A slight pressure was noted by most patients, but none had pain. No side effects of the infusion were noted.  (+info)

Hyaluronan synthase expression in bovine eyes. (4/1498)

PURPOSE: Hyaluronan (HA), a high-molecular-weight linear glycosaminoglycan, is a component of the extracellular matrix (ECM). It is expressed in eyes and plays important roles in many biologic processes, including cell migration, proliferation, and differentiation. Hyaluronan is produced by HA synthase (HAS), which has three isoforms: HAS1, HAS2, and HAS3. In this study, the HAS expression in the anterior segment of bovine eyes was investigated to determine the significance of HA in eyes. METHODS: To obtain bovine HAS probes, degenerate oligonucleotide primers, based on well-conserved amino acid sequences including the catalytic region of each HAS isoform, were used for reverse transcription-polymerase chain reaction to amplify mRNA from bovine corneal endothelial cells (BCECs). Hyaluronan synthase-1 expression in the anterior segment of bovine eyes at the protein level was investigated by immunohistochemistry. RESULTS: All three HAS isoforms were expressed in BCECs at the mRNA level. Amplified cDNA fragments of HAS1, HAS2, and HAS3 from BCECs can be aligned to human counterparts, showing similarities of 100%, 97.3%, and 100%, respectively, at the amino acid level. Hyaluronan synthase 1 was expressed at the protein level in corneal epithelium, keratocyte, corneal endothelium, conjunctival epithelium, ciliary epithelium, capillary endothelium, and trabecular meshwork. CONCLUSIONS: Hyaluronan synthase isoforms were expressed in the ocular anterior segment and are speculated to be involved in HA production in situ.  (+info)

Effects of benzalkonium chloride on growth and survival of Chang conjunctival cells. (5/1498)

PURPOSE: The aim of this study was to investigate the action of benzalkonium chloride (BAC), used as a preservative in most ophthalmic topical solutions, on epithelial conjunctival cells in vitro. METHODS: A continuous human conjunctival cell line (Wong-Kilbourne derivative of Chang conjunctiva) was exposed to BAC solutions at various concentrations (0.1%-0.0001%) during a period of 10 minutes. Cells were examined before treatment and 3, 24, 48, and 72 hours later, after reexposure to normal cell culture conditions. Cell number and viability were assessed with crystal violet and 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyl tetrazolium bromide colorimetric assays. The expression of the apoptotic marker Apo 2.7, nuclear antigen p53, membrane proteins Fas and Fas ligand, and DNA content was studied by flow cytometry. Morphologic aspects of cell nuclei were analyzed on slides with a nucleic acid-specific dye, 4',6'-diamidino-2-phenylindole dihydrochloride. Cytoskeleton was labeled with a monoclonal anti-pancytokeratin antibody. In addition, apoptosis was measured by DNA electrophoresis assays in agarose gel. RESULTS: Cell exposure to 0.1% and 0.05% BAC induced cell lysis immediately after treatment. All cells (100%) treated with 0.01% BAC died in a delayed manner within 24 hours, with most of the characteristics of apoptosis (chromatin condensation and DNA fragmentation, reduction in cell volume, expression of the apoptotic marker Apo 2.7, and apoptotic changes in DNA content). Aliquots of 0.005%, 0.001%, 0.0005%, and 0.0001% BAC induced growth arrest and apoptotic cell death in a dose-dependent manner between 24 and 72 hours after treatment. The expressions of Fas and p53 did not vary after BAC treatment. Fas ligand was always negative. CONCLUSIONS: These results suggest that BAC induces cell growth arrest and death at a concentration as low as 0.0001%. The mode of BAC-induced cell death is dose-dependent. Cells die by necrosis after BAC treatment at high concentrations and by apoptosis if low concentrations of BAC are applied. This new aspect of in vitro toxicity of BAC could in part explain some ocular surface disorders observed in patients undergoing long-term topical treatments with preservative-containing drugs.  (+info)

A single amino acid in the adenovirus type 37 fiber confers binding to human conjunctival cells. (6/1498)

A 46-kDa receptor, coxsackievirus-adenovirus (Ad) receptor (CAR), mediates cell attachment of a number of different Ad serotypes; however, not all Ad serotypes utilize this receptor for infection. Moreover, the precise amino acid sequences in the Ad fiber protein that mediate cell attachment have yet to be identified. We investigated the interaction of subgroup D Ads with human ocular cells. Ad serotype 37 (Ad37), a virus associated with epidemic keratoconjunctivitis, but not a closely related virus serotype, Ad19p, exhibited preferential binding to and infection of human conjunctival cells. A single amino acid substitution in the Ad19p fiber distal domain (knob), Glu240 to Lys, conferred binding to conjunctival cells, while the reverse substitution in the Ad37 fiber abrogated cell binding. These findings provide new information on the fiber sequences that regulate Ad host cell tropism.  (+info)

Ocular injuries from liquid golf ball cores. (7/1498)

Tissue removed from nine new cases from 18 hours to 20 weeks after injury by a golf ball contained crystalline and other foreign material to which there was a mild inflammatory reaction followed by macrophagic activity and fibrosis. Optical and electron probe analysis showed that the crystalline material was crushed barytes containing small quantities of muscovite as is typical in natural deposits. The centres of several golf balls were shown to contain essentially identical material. By contrast with previous reports, no zinc sulphide was found. The form and frequent location of the deposits in the conjunctiva as compared with cornea and eyelid is related to the structure of these tissues.  (+info)

Conjunctival epithelial cell differentiation on amniotic membrane. (8/1498)

PURPOSE: Amniotic membrane (AM)-reconstructed conjunctival surfaces recover the normal epithelial phenotype with a significantly higher cell density than the control. The present study was undertaken to examine how AM modulates rabbit conjunctival epithelial cell differentiation. METHODS: Rabbit conjunctival epithelial cells (RCEs) were cultured on the basement membrane side of dispase-pretreated AM, with or without seeding rabbit conjunctival fibroblasts (RCFs) on the stromal side. After 7 to 12 days, half of the cultures were raised to the air-liquid interface, and the remainder stayed submerged. A small group of air-lifted cultures containing RCFs was treated with retinoic acid. After 1, 2, and 4 weeks, cultures were terminated and processed for immunostaining with antibodies directed against distinct types of mucins (SMC and AM3), glycocalyx (AMEM2), keratin K3 (AE5), and K12 (AK2). Additionally, western blot analysis was performed for K3 keratin expression. Ultrastructural changes were evaluated by transmission electron microscopy. RESULTS: In general, RCEs grown on AM were uniformly small, negative to AE5 and AK2 antibodies, and positive to AMEM2 and ASPG1 antibodies. Epithelial stratification and cell polarity with prominent microvilli, tight junctions, and hemidesmosomes were more pronounced in air-lifted cultures. RCEs cocultured with RCFs showed scattered AM3-positive goblet cells, which were not increased by retinoic acid. CONCLUSIONS: RCEs cultured on AM primarily exhibit a nongoblet conjunctival epithelial phenotype. Epithelial stratification and cell polarity, features essential for epithelial differentiation, are promoted by air-lifting. This culture model will be useful for studying how growth and differentiation of conjunctival epithelial cells can be modulated further.  (+info)

Purpose : TRPV cation channels are osmo-mechano-and-thermo-sensitive membrane proteins. These proteins are extensively involved in pathophysiology including inflammation and pain. Hyperosmotic tears and ocular surface inflammation are hallmarks of dry eye condition. Here we explore expression and osmotic modulation of TRPV1 and TRPV4 in human conjunctival epithelial cells (hCjE). Methods : hCjE cells were cultured to confluence in supplemented Keratinocyte Serum Free Medium (GIBCO). Presence of TRPV mRNA and proteins in hCjE were determined by Reverse Transcription-Quantitative-Polymerase Chain Reaction (RT-qPCR) and western blot analysis, respectively. Results : The RT-qPCR and western blot studies confirm the presence of TRPV1, TRPV2 and TRPV4 mRNA and proteins in hCjE cells. None of the TRPC genes were detected in the hCjE cells. Incubation of hCjE cells for 24h with 5 μM GSK 1016790A (a specific TRPV4 agonist) upregulated the TRPV4 gene by 58 folds (SEM=0.23, N=3, P=0.0001) compared to ...
Purpose: : Epithelial cells from several mucosal sites (including conjunctiva) have been shown to actively participate during inflammatory episodes by producing and secreting cytokines and chemokines. The aim of this study was to determine the pattern of cytokines/chemokine secretion from conjunctival epithelial cells under the effect of Th1 and Th2-type cytokines to further clarify the role of conjunctival epithelium in ocular surface inflammation. Methods: : IOBA-NHC (normal human conjunctival) epithelial cells were exposed to Th1- (IFN-γ and TNF-α) or Th2- (IL-4 and IL-13) derived cytokines for 48 h. Time dependency (30 min, 2 h and 24 h) of TNF-α induced cytokine/chemokine secretion was additionally studied. Cytokine/chemokine production was determined in supernatants by a 22-multiplex bead-based assay in a Luminex 100-IS. Additionally, eotaxin-2 and -3 production was analyzed with by ELISA. Results: : After 48 h of Th1 stimulation, cells produced high levels of IL-1α, IL-6, IL8, RANTES ...
The conventional technique of impression cytology provides a non-invasive method for the evaluation of conjunctival epithelium alterations. Using indirect immunofluorescence procedures two inflammatory markers, class II MHC antigens HLA DR and the receptor to IgE (CD23), were sought in impression cytology specimens obtained from 80 patients. In normal subjects conjunctival epithelial cells did not show any reactivity. Only scattered dendritic cells were found to express class II antigens but not the receptor to IgE. In contrast patients with chronic conjunctivitis of various aetiologies, mainly infectious or allergic, had 40-100% of brightly positive conjunctival cells for one or both antigens. In these cases epithelial cells and goblet cells reacted similarly. Twenty four eyes in 12 patients with idiopathic dry eye syndrome disclosed results similar to those from normal conjunctival specimens. However 18 other specimens from patients suffering from idiopathic tear deficiency but undergoing ...

Therefore, our study has that all the components for this particular fibroblast/T cell interaction were present in human conjunctiva.. T cell/fibroblast interactions appear to have an important role in the development of abnormal scarring.2 Hitchings and Grierson showed that early trabeculectomy failures were associated with excessive inflammation and increased conjunctival fibroblast numbers.14 Nuzzi et al demonstrated that the preoperative conjunctiva of repeat filtration surgery patients contained an increased number of activated T lymphocytes and fibroblasts.15 In our study, T lymphocytes and IFNβ producing ...

Location of the redness can be important so a brief review of eye anatomy is important. The term conjunctivitis means inflammation of the conjunctiva (singular) or conjunctivae (plural). The conjunctiva is usually described as having three parts, all of which are thin, transparent layers of mucous membrane. The most external and easily observable portion is that which overlies the white portion (sclera) of the eyeball itself. This is called the bulbar or ocular conjunctiva. It covers the entire sclera, but it does not cover the central anterior portion of the eyeball (the cornea). That is, it extends onto the eyeball up to, but not beyond, the limbus. The limbus is the union of the cornea and the sclera and a conjunctivitis limited to the limbus is an important clue to more serious cause of a red eye. When the bulbar conjunctiva is normal (not inflamed), it cannot be differentiated from the sclera beneath it, because it is clear. Another portion of the conjunctiva, visible if the eyelids are ...
bulbar-conjunctiva definition: Noun (plural bulbar conjunctivas or bulbar conjunctivae) 1. (anatomy) One of three parts of the conjunctiva, the bulbar conjunctiva is the conjunctiva covering the eyeball, over the sclera. ...
Disorders of the conjunctiva and cornea are a common source of eye complaints. The surface of the eye is exposed to various external influences and is especially suspectible to trauma, infections, and allergic reactions. The conjunctiva is best known because of its inflamed state, conjunctivitis (more commonly known as pinkeye). Conjunctival irritation is one of the adverse health effects that can take place after overexposure to VOCs (Volatile organic compounds). ...
NHE8, the latest characterized NHE isoform in the NHE family, has been shown to participate in transmembrane electrolyte exchange and mucosal protection in the intestine and the kidney (25, 49-51). Although NHE8 is expressed in the epithelial cells in the intestine and the kidney, whether NHE8 is expressed in the ocular surface epithelia remains unknown (25, 49). In the present study, we showed that NHE8 mRNA is expressed in human and mouse eyes. Similar to NHE8 protein localization in the intestinal epithelial cells (49, 50), NHE8 is also located at the plasma membrane of the epithelial cells in the conjunctiva, the cornea, and the lacrimal glands in human and mouse eye tissues. The presence of NHE8 in the ocular surface epithelia suggests a possible role of this protein in ocular function.. Tear film plays a very important role in ocular protection. It is believed that the majority of tears is produced by lacrimal glands, but the ocular epithelial cells, especially conjunctiva, could also ...
Intestinal epithelial cells condition tolerogenic properties in DCs. Aqueous-deficient dry eye is associated with goblet cell (GC) loss and increased IFN-γ expression in the conjunctiva. We hypothesized that loss of GCs reduces tolerance-inducing properties of antigen presenting cells (APCs) in the conjunctiva and draining nodes. Mice lacking the SAM pointed domain containing ETS transcription factor (Spdef) that is required for GC differentiation had an increased frequency of macrophages in the conjunctiva and CD11b+CD11c+ DCs in the conjunctiva and draining nodes, and these cells had greater IL-12 expression than WT mice. Conditioned media from cultured WT conjunctival GCs suppressed LPS-induced IL-12 production by conjunctival APCs. OVA antigen-specific OTII CD4+ T cells primed by Spdef-KO draining lymph node APCs showed greater proliferation, lower frequency of Foxp3+, increased frequency of IFN-γ+ and IL-17+ cells, and greater IFN-γ production than those primed by WT APCs. The immune ...
The substantia propria (or stroma of cornea) is fibrous, tough, unyielding, and perfectly transparent. It is composed of about 200 flattened lamellæ, superimposed one on another.[1] These fibrils run at different angles between limbi. Fibres of the layers frequently interweave, the anterior lamellæ interweaving more than posterior lamellæ. The fibres of each lamella are parallel with one another, but at right angles to those of adjacent lamellæ. The lamellæ are produced by keratocytes, which occupy about 10% of the substantia propria. These lamellæ are made up of bundles of modified connective tissue, the fibres of which are directly continuous with those of the sclera. More collagen fibres run in a temporal-nasal direction than run in the superior-inferior direction. This is often ignored by corneal transplant surgeons, leading to poor corneal mechanical strength in corneal transplant patients. Keratoconus is a condition caused by disorganised lamellæ, leading to a bulbous cornea. ...

Conjunctivitis - which is also known as pink eye - is an inflammation of the conjunctiva. The conjunctiva is a thin transparent layer that covers the white part of your eye. Inflammation of the conjunctiva is considered very common especially among children in school age. It is also very contagious and can be transmitted from one person to another.. Many things can cause this inflammation including viruses, bacteria, allergic agents such as dust and other chemicals that can irritate such as smoke and certain shampoos. Conjunctivitis is not considered a major problem, but you should still be careful. If your baby has a pink eye, you should immediately consult a doctor ...

Aaron Feser, O.D.. When our eyes are uncomfortable, the answer or reason is usually not as simple as you might think. Allergies, poor tear film, plugged oil glands, oral medications, systemic health problems (example arthritis), or a combination of those issues and others can certainly make our eyes itch and burn.. The term that is used to describe those factors together is Ocular Surface Disease. The ocular surface is the tissues that make up the front surface of the eye. They include the cornea, tear film, eyelids, and conjunctiva (the clear covering over the "whites" of our eyes). When the ocular surface is inflamed it not only causes discomfort, but also affects the quality of our vision. We all know that inflammation in the joints in our body give us achy hands and knees, for example. Inflammation also makes our ocular surface hurt. The doctors and staff at Vision Care Associates are dedicated to providing you with the most clear and comfortable vision possible which goes beyond the ...

The conjunctiva is a mucous membrane that covers the sclera and lines the inside of the eyelids. Throughout the conjunctiva are goblet cells that secrete mucins to protect the eye. Chronic inflammatory diseases such as allergic conjunctivitis and early dry eye lead to increased goblet cell mucin secretion into tears and ocular surface disease. The purpose of this study was to determine the actions of the inflammatory mediators, the leukotrienes and the proresolution resolvins, on secretion from cultured rat and human conjunctival goblet cells. We found that both cysteinyl leukotriene (CysLT) receptors, CysLT(1) and CysLT(2,) were present in rat conjunctiva and in rat and human cultured conjunctival goblet cells. All leukotrienes LTB(4), LTC(4), LTD(4), and LTE(4), as well as PGD(2), stimulated goblet cell secretion in rat goblet cells. LTD(4) and LTE(4) increased the intracellular Ca(2+) concentration ([Ca(2+)](i)), and LTD(4) activated ERK1/2. The CysLT(1) receptor antagonist MK571 ...
Purpose: To compare the outcomes of conjunctival autograft fixation using autologous serum vs fibrin glue to cover the bare sclera in pterygium excision surgery.. Study Design: Quasi experimental study.. Place and Duration of Study: The study was conducted in Ophthalmology Department of CMH Kharian from April 2018 to November 2018.. Material and Methods: Forty patients with primary pterygium were selected by convenient sampling technique. Patients with recurrent Pterygia and moderate to severe dry eyes, keratitis or secondary to trauma were excluded. The patients were divided into two groups, group A treated with fibrin glue and group B treated with autologous serum technique. All patients underwent pterygium excision under topical anaesthesia. The conjunctival autograft was removed from superior temporal bulbar conjunctiva to cover the scleral bed produced by pterygium excision. Post operatively the patients were followed-up for three months to assess the fixation or otherwise. Data was noted ...
Concretion in the palpebral conjunctiva, is called conjunctival concretion, that is a (or a cluster) small, hard, yellowish-white calcified matter, superficially buried beneath the palpebral conjunctiva. Most of concretions in the eye form in the palpebral conjunctiva, which is a clear membrane to surround the inside of the eyelid. Less can be located in the cornea and retina. Chronic conjunctivitis (e.g. trachoma) and aging factor are two causes of conjunctival concretion, which will make the conjunctiva cellular degeneration to produce an epithelial inclusion cyst, filled with epithelial cells and keratin debris. After calcification, the conjunctival cyst hardens and forms a conjunctival concretion. Congenital conjunctival concretion condition is also more common. Conjunctival concretions are generally asymptomatic. Common symptoms include eye discomfort, eye irritation, and foreign body sensation. Sometimes, the larger, harder or multiple concretions make the rubbing off of the superficial ...
PURPOSE: To evaluate the effects at 1 year of preservative-free timolol gel and preserved timolol eye drops on conjunctiva and tear parameters. METHODS: Forty patients with primary open-angle glaucoma or ocular hypertension were randomized to the two treatment groups and compared with 20 healthy age-matched controls. Clinical tests (IOP, Schirmer I test, and lacrimal film break-up time BUT) and in vivo conjunctival confocal microscopy (IVCM) were performed in all patients at baseline and after 12 months. IVCM (HRT II Rostock Cornea Module; Heidelberg Engineering GmbH, Heidelberg, Germany) was performed after topical anaesthesia in the four cardinal locations and at the corresponding limbus to analyse conjunctiva cells. The main IVCM outcomes were goblet cell density and epithelial regularity. RESULTS: IVCM and clinical parameters were similar in the three groups at baseline. After 12 months, intra-epithelial goblet cell density was significantly lower in the preserved (48.25 ± 7.70) than in the ...
Patients with recurrent pterygia without symblepharon were randomly assigned to undertake pterygium excision followed by amniotic membrane associated with a small conjunctival autograft (2x3mm) or conjunctival autograft (approximately 5x8mm) alone. The patients were examined after 1, 7, 30, 90, 180 and 360 days after the surgery. Recurrence was considered as a fibrovascular ingrowth of 1.5 mm or more beyond the limbus with conjunctival drag ...

Purpose: Scarring after glaucoma filtering surgery remains the most frequent cause for bleb failure. The aim of this study was to assess if the postoperative injection of bevacizumab reduces the number of postoperative subconjunctival 5-fluorouracil (5-FU) injections. Further, the effect of bevacizumab as an adjunct to 5-FU on the intraocular pressure (IOP) outcome, bleb morphology, postoperative medications, and complications was evaluated. Methods: Glaucoma patients (N = 61) who underwent trabeculectomy with mitomycin C were analyzed retrospectively (follow-up period of 25 ± 19 months). Surgery was performed exclusively by one experienced glaucoma specialist using a standardized technique. Patients in group 1 received subconjunctival applications of 5-FU postoperatively. Patients in group 2 received 5-FU and subconjunctival injection of bevacizumab. Results: Group 1 had 6.4 ± 3.3 (0-15) (mean ± standard deviation and range, respectively) 5-FU injections. Group 2 had 4.0 ± 2.8 (0-12) (mean ±

Visual health consists of many aspects of the eye, including parts you cannot see on the surface of the eye. Learning the structures and functions of the eye are the best way to understand how to keep the eyes healthy and why eye diseases may occur. Here is an overview of the anatomy of the human eye.. Eyelid. The eyelid consists of two movable folds which protect the eye. At the edge of the eyelid are 2 to 3 rows of eyelashes, called CILIA. The eyelids consist of multiple layers. From outer to inner most layer: the skin, subcutaneous areolar, orbicularis layer, orbital septum, superior levator palpebrae muscle, muscle of muller, tarsal plate, and palpebral conjunctiva.. Fun fact: When you see someone flipping their eyelid over, that pinkish area is called the palpebral conjunctiva. This is an immunologically active layer filled with macrophages and mast cells, which provide a defense against foreign invaders.. Lacrimal System. The lacrimal system produces and drains the tears. The LACRIMAL ...
Introduction Vernal keratoconjunctivitis (VKC) is a recurrent, bilateral, interstitial inflammation of the conjunctiva, resolving spontaneously after a course of several years and characterised by giant papillae (with a cobblestone appearance) on the tarsal conjunctiva, a discrete or confluent gelatinous hypertrophy of the limbal conjunctiva, and a distinct type of keratitis. It is associated with intense…
Pinguecula and Pterygium are common, non-cancerous growths on the cornea (clear part of the eye) and conjunctiva (white of the eye) likely caused by exposure to ultraviolet (UV) light. Chronic ocular surface inflammation from dry eye, allergies, wind and dust can further aggravate the area. They are often seen in patients with extended time spent in the sun without protection.. These growths are usually not serious and can be safely removed by our experienced eye surgeons. Reasons for seeking surgical management may be unrelenting symptoms of foreign body sensation/ eye irritation, growth into the visual axis, or induced irregular astigmatism limiting best correction visual potential.. ...
The conjunctival cells are collected by impression cytology. Those cells are stained with 100 mM of monochlorobimane (MCB, M-1381, Molecular Probes, Eugene, OR) and propidium iodide (PI). Fluorescent intensity, reflecting the amount of icGSH, was inspected under a confocal laser scan microscope. To detect the GSH levels we used a fluorescent MCB probe with excitation and emission wavelengths of 405 nm and 410-480 nm, respectively. The cell-permeating MCB probe is non-fluorescent but forms a fluorescent adduct with GSH in a reaction catalyzed by glutathione-S-transferase ...

To the Editor: The ocular condition called pterygium (also known as web eye) is a triangular patch of hypertrophied subconjunctival tissue extending from the medial canthus of the eye to the border of the cornea or beyond, with the apex pointing towards the pupil. It is one of the most common conditions of the conjunctiva, and surgery to remove pterygia is practised widely.
This MasterClass on the surgical management of primary and recurrent pterygia, will focus on conjunctival autografting techniques, and include pearls to minimize recurrence and obtain excellent cosmetic outcomes. Prevention and management of pterygium surgery complications will be highlighted, and challenging scenarios presented.. ...
The ocular surface is the first line of defence in the eye against environmental microbes. The ocular innate immune system consists of a combination of anatomical, mechanical and immunological defence mechanisms. TLRs (Toll-like receptors), widely expressed by the ocular surface, are able to recognize microbial pathogens and to trigger the earliest immune response leading to inflammation. Increasing evidence highlights the crucial role of TLRs in regulating innate immune responses during ocular surface infective and non-infective inflammatory conditions. In addition, recent observations have shown that TLRs modulate the adaptive immune response, also playing an important role in ocular autoimmune and allergic diseases. One of the main goals of ocular surface treatment is to control the inflammatory reaction in order to preserve corneal integrity and transparency. Recent experimental evidence has shown that specific modulation of TLR pathways induces an improvement in several ocular inflammatory ...
Professor Eric Donnenfeld. Professor Eric Donnenfeld, New York University, USA, delivered a presentation on the changing pharmaceutical treatment patterns in cataract surgery during a Main Symposium at the XXXV Congress of the ESCRS in Lisbon.. "Efficient drug delivery remains a significant unmet need, with topical drops facing not only problems with compliance, but also with low rates of absorption into the eye," said Prof Donnenfeld. He suggested that topical medications as we know them today will change greatly over the next several years, and he proceeded to outline the possibilities on the horizon.. "The mucoadhesive DuraSite vehicle delivers sustained pharmacokinetics, maintaining therapeutic concentrations in the human conjunctiva up to six days after the last dose," he said..

A pterygium is a triangular shaped fold of conjunctiva (the thin usually clear membrane over the white of the eye) which has grown, together with fibrous tissue and blood vessels into the adjacent cornea.. A pterygium typically arises from the inner (nasal) conjunctiva and is strongly associated with ultraviolet light (UV) exposure. Hence they usually occur in patients living in hot climates such as Indian sub-continent, Africa and Australia. Other factors such as dryness, inflammation and exposure to dust, may also play a role. Sometimes, a pterygium may not cause any problems. However, patients typically complain of:. ...

A pterygium is an abnormal growth of elastolytic (sun exposed) cells that begin to encroach and scar the cornea. Pterygium surgery involves removal of the abnormal tissue from the sclera and cornea of the eye. Todays techniques in the hands of an experienced surgeon offer a significantly higher success rate than conventional surgery. Our surgeons at Dulles Eye Associates perform NO-STITCH PTERYGIUM SURGERY WITH AN AUTOGRAFT, the latest technology in pterygium surgery. Under light sedation and local anesthesia, the abnormal corneal tissue is removed and replaced with a thin graft of normal tissue. Over the next 2-3 weeks, the eye gradually returns to a normal appearance. No stitches mean quicker healing and less discomfort.. ...

Overview View Video A pterygium is a growth of the conjunctival tissue onto the cornea. This most commonly occurs on the side closest to the nose. The growth can cause persistent redness and inflammation, vision distortion, and corneal scarring.
The Eye is shaped like a ball. The tough white outer coat is called sclera and its surface is covered by a thin layer called the conjunctiva. The clear outer layer called the conjunctiva. The clear outer layer at the front of the eye is called the cornea which is covered by the tear film. Behind the cornea is the iris - the colored part of the eye - with the pupil forming a hole in its center. The Space between the Cornea and the lens is filled with a clear fluid, called aqueous humor, which maintains the pressure in the eye (the Intraocular Pressure).. The Pressure is determined by the balance between the fluid production in the eye and its drainage out of the eye. On the inside of the back of the eye is the retina, which is the light sensitive layer onto which an image of what is being seen is focused by the cornea and the lens working together.. The central area of the retina where the most detailed vision is to be found, known as the macula, has a very high density of cells, Further away ...

Mark J. Pyle, DO is a pediatrician at Banner Health Center in Verrado. For more information on this topic, talk with your doctor or call Dr. Pyles office at 623-463-5000.. Question: What is pinkeye and how is it treated?. Answer: Pinkeye, or conjunctivitis, occurs when the thin, clear layer that sits over the white part of the eye, called the conjunctiva, becomes irritated. When the conjunctiva is inflamed, either from bacteria, virus, allergies or another irritant, the white of the eye turns reddish, and the eye can be itchy, watery and have a sticky, yellow discharge that turns crusty and dry. Pinkeye caused by bacteria or a virus is very contagious and spreads easily from person to person. This is particularly problematic for children because they often rub their eyes and then touch other people or surfaces, which quickly passes the infection to others.. The type of pinkeye that a child or adult may get can be diagnosed by a physician performing an eye exam. Bacterial pinkeye is generally ...
Pink eye, is the redness in the eye, which is caused due to inflammation of the conjunctiva. Conjunctiva is the lining that covers the eyelid and eye surface.
Any condition that reduces the production, alters the composition, or impedes the distribution of the preocular tear film (POTF) may cause a noticeable irritation to the structures of the front surface of the eye and a degradation of vision. These conditions are often related to problems with the structure or function of the eyelids, cornea, or conjunctiva. Depending upon the severity of symptoms, individuals may be limited in their ability to see clearly and comfortably and may be at increased risk of developing secondary infection or chronic inflammation that may not respond to treatment ...

Subconjunctival hemorrhage, also known as subconjunctival haemorrhage and hyposphagma, is bleeding underneath the conjunctiva. The conjunctiva contains many small, fragile blood vessels that are easily ruptured or broken. When this happens, blood leaks into the space between the conjunctiva and sclera. Such a hemorrhage may be caused by a sudden or severe sneeze or cough, or due to high blood pressure or as a side effect of blood thinners such as aspirin or warfarin. It may also be caused by heavy lifting, vomiting, or even rubbing ones eyes too roughly. In other cases, it may result from being choked or from straining due to constipation. Also, it can result as a minor post-operative complication in eye surgeries such as LASIK. Whereas a bruise typically appears black or blue underneath the skin, a subconjunctival hemorrhage initially appears bright-red underneath the transparent conjunctiva. Later, the hemorrhage may spread and become green or yellow, like a bruise. Usually this disappears ...

If you suffer from atopic keratoconjunctivitis, you may suffer from severe itching, particularly of the eye and the skin over the eye. Unlike allergic conjunctivitis, the skin around your eyes may become dry, scaly, or reddened. The skin in this area may have barely visible microwrinkles, be thickened, or have a slight increase in pigmentation from constant rubbing. Your lid margins may show loss of eyelashes. The underside of your upper lid may have islands of tissue (papillary hypertrophy) which may be irritated by contact lenses or may irritate the cornea. This complication is an important medical problem since it may result in damage to your vision if neglected. Symptoms of atopic keratoconjunctivitis may be seasonal, perennial, or both ...
The success rate of glaucoma filtration surgery is closely related to conjunctival inflammation, and the main mechanism of dry eye disease (DED) is inflammation. The aim of this study was to evaluate the effect of DED on bleb scar formation after rabbit glaucoma filtration surgery. Sixteen New Zealand white rabbits were randomly divided into control and DED groups. A DED model was induced by twice-daily topical administration of 0.1% benzalkonium chloride (BAC) drops for three weeks. Ocular examinations were performed to verify the DED model. Surgical effects were assessed, and histologic assessments were performed on the 28th postoperative day. Higher fluorescein staining scores, lower basal tear secretion levels and goblet cell counts, and increased interleukin 1β (IL-1β) levels were observed in the DED group. The DED eyes displayed significantly higher intraocular pressure (IOP)% on the 14th postoperative day; a smaller bleb area on days 14, 21 and 28; and a shorter bleb survival time. Moreover,

A subconjunctival haemorrhage is one cause of a red eye. It is caused by a small bleed behind the conjunctiva. About Subconjunctival Haemorrhage
What is atopic keratoconjunctivitis (AKC)?. AKC is the result of atopy, a genetic condition in which the immune system produces higher than normal antibodies in response to a given allergen. Although AKC is a year-round disease, symptoms may worsen in the winter. Unlike atopic dermatitis, which is generally seen early in childhood, atopic keratoconjunctivitis appears during late adolescence and early adulthood. Men are more commonly affected than women.. How do I know if I have atopic keratoconjunctivitis?. With AKC, the conjunctiva lining the eyelids is usually red and swollen, with the lower eyelid generally more affected than the upper. AKC can progress to ulceration, scarring, cataract, keratoconus, and corneal vascularization. The most common symptoms of atopic keratoconjunctivitis include:. ...
Abstract Objective: A population of stem cells (SCs) is responsible for maintenance and repair of the ocular surface. These stem cells can become deficient as a result of various diseases affecting the ocular surface. Depending on the extent of damage, the clinical features can vary from mild discomfort to substantial pain and/or blindness. The growing field of tissue engineering and advances in stem cell research offer promising new alternatives for these disorders. This student thesis will provide an overview of the human ocular surface (cornea, limbus, and conjunctiva), ocular surface stem cell deficiency, and treatment possibilities. Methods: This student thesis is based on a number of review articles and original articles on PubMed using the search words limbal, limbal stem cell deficiency, conjunctival and/or ocular surface reconstruction. Only papers written in English were considered. Findings: There are different possible methods for treating ocular surface stem cell deficiency by ...
Purpose: To compare the results of trabeculectomy with subconjunctival Bevacizumab and 5-Fluorouracil (5-FU); with trabeculectomy with 5-Fluorouracil alone in the short term (i.e. 3 months).. Study Design: Prospective, interventional study. Place and Duration of Study: Department of Ophthalmology, Fauji Foundation Hospital, Rawalpindi, from 18th December 2013 till 16th August 2018.. Material and Methods: A total of 30 eyes (15 in each group) in patients above 40 years of age with primary glaucoma, underwent trabeculectomy with 5-Fluorouracil (5-FU) (50 mg/ml) applied for 5 minutes. At the end of surgery, sub-conjunctival Bevacizumab (Avastin® 2.5 mg in 0.1 ml) was injected in one group. The postoperative IOP, bleb configuration, and complications at 1 day, 1 week, 1 month, and then monthly for 3 months was observed for both groups.. Results: The mean pre-operative IOP in the 5-FU group was 30.6 ± 17.1 mm Hg compared to 28.9 ± 18.9 mm Hg in the 5-FU + Bevacizumab group. The mean IOP of the ...
In this study, we found increased expression of the pro-inflammatory cytokines IL-1β and TNF-α in the corneal and conjunctival epithelium of BTX-B lacrimal gland-injected mice over 4 weeks, coincident with observed tear production decrease and corneal fluorescein staining increase. We have confirmed that ocular surface inflammation develops in the BTX-B induced dry eye mouse model. Comparing normal and saline-injected mice, IL-1β and TNF-α mRNA expression in the corneal and conjunctival epithelia significantly increased in BTX-B injected mice at 1 and 2 weeks after injection, and decreased back toward baseline at 4 weeks, especially IL-1β. Immunohistological staining results support the findings of the gene expression study. These changes were also consistent with observed alterations in tear production. In a previous study, we found that IL-1β and TNF-α expression in the lacrimal gland did not increase, but they were increased in corneal and conjunctival epithelia in BTX-B injected mice ...
What is Atopic keratoconjunctivitis(AKC) - comprehensive overview covers symptoms, causes, risk factors, tests & diagnosis, treatment options.
The conjunctiva is a relatively loose structure and any bleeding can easily spread and appear quite alarming. Patients are, however, often asymptomatic and may only become aware of having a red eye when looking in the mirror or having it pointed out to them.. The majority of subconjunctival haemorrhages occur spontaneously without an identifiable cause, the patient occasionally complaining of a sudden "popping" feeling in the eye. It is likely that many of these patients may have had mild trauma eg eye rubbing, which has contributed to the bleed.. ...
Recorded on Saturday, October 28, 2017. Wills Eye Hospital, 840 Walnut Street, Philadelphia, PA (Auditorium -- 8th Floor). Christopher J. Rapuano, MD - Program Chair. Last Review Date - October 28, 2017. Course Description: The management of ocular surface disease is often complicated, including seeking the presence of an underlying systemic condition, the use of topical and occasionally oral medications to control the inflammation and improve the health of the cornea and conjunctiva. This conference will review the current strategies for evaluation and management of these patients. At the conclusion of this conference, participants should be able to:. Evaluate patients with ocular surface disease in a systematic fashion. Develop a strategy to best manage patients with a variety of ocular surface conditions. Assess the rationale for medical & surgical treatment of conjunctivochalasis Counsel patients undergoing cataract surgery as to the effect of their OSD on their outcomes. Accreditation ...
Conjunctiva occupies most of the ocular surface area, and conjunctival permeability affects ocular and systemic drug absorption of topical ocular medications. Therefore, the aim of this study was to obtain a computational in silico model for structure-based prediction of conjunctival drug permeability. This was done by employing cassette dosing and quantitative structure-property relationship (QSPR) approach. Permeability studies were performed ex vivo across fresh porcine conjunctiva and simultaneous dosing of a cassette mixture composed of 32 clinically relevant drug molecules with wide chemical space. The apparent permeability values were obtained using drug concentrations that were quantified with liquid chromatography tandem-mass spectrometry. The experimental data were utilized for building a QSPR model for conjunctival permeability predictions. The conjunctival permeability values presented a 17-fold range (0.63-10.74 × 10−6 cm/s). The final QSPR had a Q2 value of 0.62 and predicted ...

Pre- and intraoperative mitomycin C for recurrent pterygium associated with symblepharon Isyaku MohammedDepartment of Ophthalmology, Aminu Kano Teaching Hospital, Kano, NigeriaBackground: Treatment of recurrent pterygium associated with symblepharon usually involves the use of tissue grafting and/or the intraoperative application of mitomycin C (MMC). For the graft, a conjunctival/limbal autograft and/or amniotic membrane may be used. This generally requires extra technical skills and assistance, an increase in the cost and duration of surgery, and a more extensive anesthesia (a complete eye block or general anesthesia). Although widely used, safety concerns have been raised over MMC in the treatment of pterygia.Objective: The objective of this case report is to report the successful use of preoperative subconjunctival injection of low-dose (0.02%) MMC one month before bare sclera excision of a multirecurrent pterygium, as well as the concomitant intraoperative application of MMC to the conjunctival

Ocular thelaziosis caused by Thelazia callipaeda is a vector-borne disease affecting dogs and humans. We report a case of thelaziosis in a 10-year-old German Shepherd dog from Vila Real city (Portugal). Ophthalmological examination revealed bulbar and nictitating membrane conjunctival hyperemia with serous discharge noted at the left medial canthus and blepharitis. Schirmer tear test value and intraocular pressure were within the reference ranges in both eyes, and biomicroscopy showed a transparent cornea without lesions or edema and no inflammatory reaction in the anterior chamber. No funduscopic alterations were detected by direct and indirect ophthalmoscopic examination. When testing the nasolacrimal patency, two white worms were observed on the caruncle conjunctival surface with undulating movements that increased with light intensity. In total, eight worms were collected and morphologically identified as T. callipaeda (seven mature females and one male). PCR amplification of a 689 sequence ...
