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)

N2 - Purpose. Recently epithelial cells are considered to be involved in the regulation of immunological reactions. We examined whether three types of Fc gamma receptors including Fcg RI, II, III (CD64, CD32, CD16, respectively) were expressed in human conjunctival epithelial cells. Methods. Conjunctival epithelial cells were isolated from normal human volunteers by brush cytology. Human conjunctival epithelial cell line (ChWK) was also used for the following analysis. Expression of Fc gamma receptors on thses cells were analyzed by indirect immunofluorescence using a flow cytometry. To characterize Fc gamma receptor, biotin-labeled cells were lysed and immunoprecipitated, followed by SDS-PAGE, and blotting onto PVDF membrane. The signals were detected by ECL chemiluminescent system. Furthermore, ...
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 ...

The aim of this study was to investigate whether the components for fibroblast mediated prevention of T cell apoptosis were present in vivo in human conjunctiva. This is the first report of the in vivo production of IFNβ by HTF, staining positive in the conjunctiva of three of our glaucoma patients. In addition, the conjunctiva of our glaucoma patients contained T lymphocytes. 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 ...

Shunting to the subconjunctival space involves the mechanism of diverting aqueous humor to the subconjunctival space from an ab interno stent placed in the angle through a clear corneal incision. The device was created to solve a major problem with tube shunts and trabeculectomy, which is that pressure can reduce, but prevention of hypotony relies on subjective scarring and suture tightness. Shunting to the sub conjunctiva was designed to prevent excessively low pressures and reduce reliance on subjective measures to dictate flow. A bleb is created but it is a more diffuse, low, and less cystic bleb than that with a trabeculectomy. A comfort level with treating blebs post-operatively, such as needling, is required so likely glaucoma specialists and those comfortable with trabeculectomies will find the benefit of this procedure most.. ...

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 ...

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). ...
Conjunctiva (of the eye) - a thin delicate mucous membrane that covers the front of the eyes and also lines the insides of the eyelids. The thickness and other characteristics of the conjunctiva vary according to location across the front of these eye.
The bulbar conjunctival microvessels are typically imaged with a high-magnification slit lamp with green filters.[24][25][26] With such high-magnification imaging systems, it is possible to see groups of individual red blood cells flowing in vivo.[24] Fundus cameras may also be used for low-magnification wide field-of-view imaging of the bulbar conjunctival microvasculature. Modified fundus cameras have been used to measure conjunctival blood flow [27] and to measure blood oxygen saturation.[23] Fluorescein angiography has been used to study the blood flow of the bulbar conjunctiva and to differentiate the bulbar conjunctival and episcleral microcirculation.[28][29][30] ...
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 ...
An Osaka University research team has succeeded in creating conjunctival cells from induced pluripotent stem cells, also known as iPS cells.
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 ...
The purpose of this research is to compare the histological and immunohistochemical changes induced by fixed combinations of timolol maleate and prostaglandin analogues in the rabbit conjunctiva. Thirty left eyes of rabbits, divided into three groups, were treated for 30 days with the following combinations of drugs: bimatoprost 0.03% + timolol 0.5%, travoprost 0.004% + timolol 0.5% and latanoprost 0.005 + timolol 0.5%. The right eyes served as controls and received no medication. At the end of the experiment, after enucleation, the conjunctivas were assessed through histomorphometry (number of inflammatory and goblet cells, epithelial thickness) and immunohistochemistry (anti-actin antibody to assess the degree of fibrosis). Histomorphometrically, there was infiltration of inflammatory cells in all the treated eyes. An increased number of goblet cells was observed with the use of all fixed combinations of prostaglandin analogues associated with timolol maleate in comparison with the control group. The
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 ...
An accurate description of human primary and recurrent pterygium histopathology was previously performed by Chui et al. in 2011 [22]. The authors launched the hypothesis that primitive cell clusters of basal epithelial cells are responsible for the invasive behavior and recurrences of human pterygium through their activation as a result of UV radiation. Using thymine dimer immunostaining, we observed clusters of intensely stained positive thymine dimer cells grouping in the basal portion of the epithelium from primary pterygium. Moreover, for recurrent pterygium, only scattered basal cells retained positivity for thymine dimers as a sign of a possible lack of the DNA repair mechanism. It is already recognized that the defects in the DNA repair mechanism can cause genetic instability, increased and uncontrolled proliferation, and irreversible errors in protein sequences [8]. The persistence of thymine dimer positive basal cells from the recurrent pterygium specimens observed in the present study ...
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 ...
Results: Patients with OA and OID demonstrated increased hyperreflectivity of corneal (71% and 78%) and conjunctival SE (63% and 42%) as compared to controls (0%). SE cell border reflectivity in the area of tight junctions was increased in the cornea for OA and OID (83%) and the conjunctiva (77% OA; 70% OID) compared to controls (0% cornea; 11% conjunctiva). While central corneal DC density was lower in acute OA (46.8±31 cells/mm2) vs. acute OID (83.7±37) cases, patients with chronic OA (256.3±243) had higher DC density compared to chronic OID (65.6±56; p,0.05). In the peripheral cornea, a 35% (acute OA) and 90% (chronic OA) increase in DC density was observed as compared to controls. Moreover, conjunctival DC density was significantly increased in both OA (131.2±100) and OID (234.4±206) as compared to controls (17.5±16.2; p,0.05). Finally, conjunctival vessels demonstrated increased immune cell adhesion in OA (5.5±0.7 cells/100μm vessel length) and OID (5.7±1.7) compared to controls ...
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 ...
Staphylococcus epidermidis is the most common pathogen in postoperative endophthalmitis and causes various infectious eye diseases. However, there is very little information on fluoroquinolone antibiotic resistance to S. epidermidis identified in conjunctival microbe and analysis of related genes. Here, the authors investigated the rate of resistance to fluoroquinolones of Staphylococcus epidermidis isolated from normal conjunctival microbes and mutations in the quinolone-resistance determining region (QRDR). 377 eye samples from 187 patients who underwent intravitreal injection and cataract surgery were included. Specimens were taken from the bilateral lower conjunctival sacs using a cotton swab and cultured. The cultures were identified using MALDI-TOP MS and gyrA, gyrB, parC, and parE gene mutations of QRDR were confirmed by DNA extraction from resistant strains of S. epidermidis with a micro-dilution method using ciprofloxacin, levofloxacin, and moxifloxacin. The culture positive rate was 61.8%

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 ...

Filtration surgery is currently being acknowledged as the most effective therapeutic modality for glaucoma; however, excessive scarring of a filtering bleb often leads to surgical failure. Subconjunctival administration of drug delivery systems provides a localized and sustained delivery of antifibrotic drugs to inhibit post-operative scarring. In this study, a long-acting delivery system of Cyclosporine A (CsA) was developed using thermogelling poly-(dl-lactic acid-co-glycolic acid)-poly(ethylene glycol)-poly-(dl-lactic acid-co-glycolic acid) (PLGA-PEG-PLGA) triblock copolymers as the carrier. The drug could be easily entrapped into the polymer aqueous solution by simply mixing them at room temperature, and the prepared formulation was spontaneously transformed into an in situ thermogel loaded with drugs at body temperature. The formulation exhibited a sustained in vitro release of CsA from the thermogel over 2 months. The in vivo efficacy of subconjunctival administration of the CsA-loaded ...
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..

  • Measles (rubeola) is an infectious disease caused by multiplication of a single-strand ribonucleic acid (RNA) virus of the genus Morbillivirus in the upper respiratory tract and conjunctiva. (
  • It is important to identify and treat problems of the conjunctiva, because some can indicate generalized disease or lead to blindness if not treated. (
  • In fatal disease, LASV immunostaining was most prominent in the anterior uvea, especially in the filtration angle, ciliary body, and iris and in and around vessels in the bulbar conjunctiva and peripheral cornea, where it co-localized with an endothelial marker (platelet endothelial cell adhesion molecule). (
  • This slide shows virulent Newcastle disease virus in the conjunctiva of a chicken. (
  • Keratinization, cicatrization, and symblepharon (adhesion of the palpebral conjunctiva to the bulbar conjunctiva) develop in advanced disease (see the second the image below). (
  • Chagas disease is transmitted by adult reduviid bugs that ingest trypomastigotes while taking blood meals from infected animals, and are then ingested or contaminate mucus membranes, conjunctiva , or abraded skin with fecal material. (

  • Evaluate the conjunctiva(e) for small- or medium-sized papillae, hyperemia, edema, excessive mucin, and limbal Trantas dots (clusters of necrotic eosinophils, neutrophils, and epithelial cells) (see the first image below). (
  • Does a conjunctiva (thin, transparent membrane covering the white of the eye) grow thick and red after the removal of a pterygium? (
  • Has anyone heard of pterygium conjunctiva? (
  • 12. Objective:To study the influence on the recurrence of pterygium treated by limbal stem cells and bulbar conjunctiva autograft transplantation. (
  • 23. Methods The pterygium of 126 cases (126 eyes) was excised under operating microscope and an autograft of conjunctiva was transplanted. (
  • 24. AIM : To evaluate a technique of limbal reconstruction pterygium through surgery using flaps of adjacent limbal conjunctiva . (
  • 27. Objective : Pterygium formation is the process of the arising and extending of wing-shaped fold of fibrovascular tissue from the interpalpebral conjunctiva to the cornea. (
  • A nodule of approximately 1-3 mm in size accompanying by enlarged blood vessels was observed at the right upper palpebral conjunctiva (Figure 1 C). This nodule was regarded as a recurrence. (
  • Also of interest: it is not wise to cover the resultant defect with conjunctiva, there is a risk of recurrence, which we can thus miss. (
  • Ruptured blood vessels beneath the conjunctiva may be the result of trauma, a blood disorder, or certain infectious diseases. (
  • Ophthalmomyiasis externa is infestation of ocular conjunctiva and adnexa by larval forms of flies of order Diptera. (
  • The conjunctiva can be affected by tumors which can be benign, pre-malignant or malignant. (
  • Tumors of the bulbar conjunctiva are located most commonly temporally and within the palpebral aperture. (
  • Signs and Symptoms Pingueculae are characterized by yellowish, slightly raised, interpalpebral exacerbations of tissue in the nasal and temporal bulbar conjunctiva.1-14 In most cases, pingueculae are an ancillary finding, causing little, if any, ocular symptoms. (
  • 13. Results Initial evaluation revealed the presence of an area of scleral melt and epithelial defect with an underlying calcific plaque over the necrotic area in the nasal conjunctiva . (
  • ICD-9 code 190.3 for Malignant neoplasm of conjunctiva is a medical classification as listed by WHO under the range -MALIGNANT NEOPLASM OF OTHER AND UNSPECIFIED SITES (190-199). (
  • Overall, OCT-A was successful in imaging the vasculature of melanocytic lesions of the conjunctiva and iris, but the researchers found it wasn't possible to differentiate between benign and malignant lesions. (
  • However, the circulations of the bulbar conjunctiva and palpebral conjunctiva are linked, so both bulbar conjunctival and palpebral conjunctival vessels are supplied by both the ophthalmic artery and the external carotid artery, to varying extents. (
  • 1 The iris may also be a particularly strong candidate for en face OCT-A imaging because it's flat, thin and easily accessible, though one study found visualization of non-clinically visible vessels depends heavily on iris pigmentation. (
  • In the area covering the cornea the conjunctiva is thin, transparent, and consists only of an epithelial layer called conjunctival epithelium . (
  • Microscopically conjunctiva consists of three layers- epithelium, adenoid layer, and a fibrous layer. (
  • Recently, a study expanded the list of potential anterior segment applications for OCT-A to include the assessment of melanocytic lesions of the conjunctiva and iris. (
  • Anterior segment OCTA of melanocytic lesions of the conjunctiva and iris. (
  • Limbal conjunctiva is the part of the bulbar conjunctiva which covers the limbal region and fuses with the corneal epithelium. (
  • The role of M. conjunctivae in the etiology of keratoconjunctivitis in sheep and goats remains to be determined. (
  • Collect swab of conjunctiva using an ESwab (preferred) or a sterile swab wetted with sterile saline and placed in a cup. (
  • After culturing of cotton swab samples from the conjunctiva, and using direct micrography of bacteria every 2 or 3 days after starting treatment, and once the results were negative (consecutively tested three times), the patients received cataract surgery. (
  • Because it is loosely attached to the episclera, the bulbar conjunctiva is a useful tissue to graft to weakened, ulcerated corneas. (
  • Dr. Shih adds that the study further supports the idea that conjunctiva may be a potential tissue through which SARS-CoV-2 enters the body and that its replication is 40-fold higher than that of SARS-CoV. (
  • Conclusions: AMT can effectively restore the epithelization of conjunctiva surface, inhibit scar formation and reduce complications after conjunctiva defect. (
  • Cell populations that differentially and specifically stained for some of these markers include the basal and superficial limbal/conjunctival epithelium and scattered cells within the substantia propria of the bulbar conjunctiva. (
  • The appearance of the conjunctiva usually is not sufficiently distinctive to suggest the etiologic agent, and specific diagnosis depends on history, physical examination, conjunctival scrapings and culture, Schirmer tear test, and occasionally biopsy. (
  • On physical examination, the bulbar conjunctiva of lower eye lid was swollen. (
  • The appearance of the conjunctiva usually is not enough, by itself, to allow your veterinarian to diagnose the cause with only a physical examination. (
