1/208. Sebaceous carcinoma presenting as a unilateral papillary conjunctivitis.PURPOSE: To describe a previously unreported presentation of sebaceous carcinoma, an aggressive tumor that often presents insidiously with minimal symptoms and nonspecific signs. methods: We report a 71-year-old man who presented with unilateral ocular irritation and ipsilateral, idiopathic, papillary changes of the superior palpebral conjunctiva. The patient underwent incisional biopsy of the palpebral conjunctiva followed by full-thickness excision of the involved eyelid. RESULT: Histopathologic examination established the diagnosis of sebaceous carcinoma. CONCLUSION: Unexplained asymmetric, papillary changes of the palpebral conjunctiva should arouse suspicion of sebaceous carcinoma.- - - - - - - - - - ranking = 1keywords = ocular, eye (Clic here for more details about this article) |
2/208. A case of human infection with newcastle disease virus.A case of newcastle disease virus infection in a female laboratory technician is reported for the first time in malaysia. infection was acquired by droplet infection of the eye while grinding infected chicken in the laboratory. The case was confirmed by isolation of newcastle disease virus from an eye swab taken from the subject on the first day of clinical signs. A four-fold rise of haemagglutination-inhibition titre was shown when sera on the third day of infection and 15 days later were compared.- - - - - - - - - - ranking = 0.52396049883382keywords = eye (Clic here for more details about this article) |
3/208. Ocular surface neoplasia masquerading as chronic blepharoconjunctivitis.PURPOSE: To present the clinical characteristics and difficulties in the diagnosis of various ocular surface malignancies mimicking features of chronic blepharoconjunctivitis and to summarize the current therapeutic approach and prognosis of patients. methods: Six patients with slowly evolving signs of persistent inflammation underwent a conjunctival biopsy after a prolonged course of medical treatment. The medical records of the patients were reviewed. RESULTS: Histopathologic examination of the biopsy specimens revealed intraepithelial squamous neoplasia (one patient), invasive squamous cell carcinoma (one patient), sebaceous carcinoma (two patients), and conjunctival lymphoma (two patients). CONCLUSION: Although uncommon, ocular surface malignancies may involve the conjunctiva diffusely and present as chronic conjunctivitis. A high index of suspicion and an early histopathologic examination are essential to not delay diagnosis.- - - - - - - - - - ranking = 1.4760395011662keywords = ocular (Clic here for more details about this article) |
4/208. Lingeous conjunctivitis with tracheal obstruction. A case report, with light and electron microscopy findings.A white male infant of 1 year had unilateral membranous conjunctivitis and severe laryngotracheobronchitis which required tracheostomy. Cultures from eye and throat swabs and of fluid suctioned through the tracheostomy grew many organisms, including H. influenzae, adenovirus type 3, and candida species, but he had no specific immunologic disturbance. Ligneous conjunctivitis was diagnosed. The infant's general condition responded slowly to intensive therapy but the membrane continued to slough off the regrow. The excised membrane contained massive subepithelial deposits of eosinophilic material and a moderately vascular chronic inflammatory-cell infiltrate with numerous mast cells in the perivascular spaces and the hyaline membrane. The conjunctivitis cleared when treated with topical sodium cromoglycate (Intal), a known inhibitor of mediator release from mast-cell granules. The success of Intal therapy in this case supports the theory that mast cells are involved in the pathogenesis of ligneous conjunctivitis.- - - - - - - - - - ranking = 0.26198024941691keywords = eye (Clic here for more details about this article) |
5/208. Linear IgA disease.PURPOSE: A case of linear IgA disease is reported to alert ophthalmologists and physicians to this unusual cause of chronic cicatrizing conjunctivitis. methods: Clinical records of a patient suffering from linear IgA disease were reviewed. RESULTS: A 65-year-old woman with a complicated medical history experienced rapidly progressive chronic cicatrizing conjunctivitis leading to corneal perforation. Undiagnosed gingivitis and palatal ulceration had been present for 5 years prior to the onset of ocular symptoms and vitamin C deficiency had followed the consequent dietary restrictions. A diagnosis of linear IgA disease was made on conjunctival biopsy, which demonstrated linear deposits of IgA along the epithelial basement membrane. The perforation was managed successfully with a conjunctival pediculate flap. Control of the inflammation was achieved with systemic prednisolone and cyclophosphamide but at the expense of serious systemic side-effects. CONCLUSIONS: Linear IgA disease causes progressive conjunctival cicatrization in many affected individuals.Although dapsone generally controls the inflammation, heavier systemic immunosuppression was required in this case. Involvement of skin or other mucosal surfaces may become symptomatic before the conjunctivitis, and physicians must be educated to refer patients for ophthalmological review on diagnosis. Conversely, ophthalmologists encountering ocular linear IgA disease should be aware of the possibility of other mucosal involvement requiring physician intervention.- - - - - - - - - - ranking = 1.4760395011662keywords = ocular (Clic here for more details about this article) |
6/208. Cicatrizing conjunctivitis associated with paraneoplastic lichen planus.PURPOSE: To report two cases of cicatrizing conjunctivitis associated with paraneoplastic lichen planus. methods: case reports. RESULTS: Two patients were examined because of redness and discomfort in both eyes. A 63-year-old woman with follicular, small-cleaved cell lymphoma had cicatrizing conjunctivitis, stomatitis, vulvitis, and skin lesions. A 25-year-old man with malignant thymoma had cicatrizing conjunctivitis, erosive stomatitis, and penile papules. Histopathologic studies of conjunctiva and skin biopsy specimens in the first patient and labial biopsy specimens in the second revealed lichen planus. CONCLUSION: Paraneoplastic lichen planus is a possible cause of cicatrizing conjunctivitis associated with inflammatory skin and mucous membrane disease.- - - - - - - - - - ranking = 0.26198024941691keywords = eye (Clic here for more details about this article) |
7/208. Ligneous conjunctivitis: a clinicopathologic study of 3 cases.The clinical, histopathologic features, and treatment outcomes in 3 patients with ligneous conjunctivitis are described. Bilateral, idiopathic membranes occurred in the palpebral conjunctiva in 2 patients. In 1 patient, unilateral conjunctival changes occurred in the bulbar conjunctiva, at the site of pterygium excision. Treatment included topical hyaluronidase, chymotrypsin, heparin, and cyclosporine and surgical excision with limited or no success. In one patient, conjunctival autografting from the normal fellow eye resulted in pseudomembrane formation at the donor site in the previously unaffected eye. Histopathological evaluation of excised membranes revealed the presence of amorphous eosinophilic hyaline material and chronic inflammatory cells. Immunohistochemical study revealed a predominance of t-lymphocytes. This case series confirms the recalcitrant clinical course of ligneous conjunctivitis. Conventional treatment modalities described in literature were not useful in the management of this condition. Surgical manipulation of the unaffected fellow eye in patients with unilateral disease can result in pathologic conjunctival changes, and is best avoided.- - - - - - - - - - ranking = 0.78594074825074keywords = eye (Clic here for more details about this article) |
8/208. bacteremia, meningitis, and brain abscesses in a hospitalized infant: complications of pseudomonas aeruginosa conjunctivitis.This report describes a preterm infant hospitalized in a neonatal intensive care unit who developed pseudomonas aeruginosa conjunctivitis associated with bacteremia, meningitis, and multiple brain abscesses. P. aeruginosa conjunctivitis can rapidly progress to an invasive eye infection, such as corneal ulceration or endophthalmitis, leading to poor vision or blindness. Progression of this infection may lead to systemic disease. However, as illustrated in this report, P. aeruginosa conjunctivitis may be associated with the development of systemic complications such as bacteremia and meningitis in the absence of invasive eye disease. P. aeruginosa is a relatively common cause of conjunctivitis in hospitalized preterm and low birth weight infants. Given the severity of the ocular and systemic complications of Pseudomonas conjunctivitis, clinicians are reminded that prompt detection and treatment of neonatal conjunctivitis is critical.- - - - - - - - - - ranking = 164.96339951746keywords = eye infection, ocular, eye (Clic here for more details about this article) |
9/208. Ligneous conjunctivitis: biochemical evidence for hypofibrinolysis.Ligneous conjunctivitis (LC) is a rare disease of unknown etiology characterized by the growth of "woody" plaques on ocular and extraocular mucosa. These lesions are comprised of fibrin and both direct and indirect evidence implicates hypofibrinolysis as the primary defect in LC. To further elucidate the pathophysiology of LC we investigated the biochemical aspects of ligneous lesions with respect to the fibrinolytic system. Ligneous lesions were obtained from the right eye of a 15 year-old female patient with longstanding LC since age 2.5 year. Ligneous conjunctivitis in this patient has exhibited a chronic recurrent coarse and has involved multiple muscosal sites. Samples analyzed included an abundant mucoid thread from the conjunctival fornix and the ligneous plaque attached to the inferior tarsus. Samples were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) to characterize protein profiles and by a variety of zymographic methods to visualize fibrinolytic enzymes. We found that mucoid and ligneous samples were distinct entities. Specifically, ligneous samples contained polypeptides with electrophoretic profiles characteristic of intact fibrin, and were replete in fibrin-bound tissue plasminogen activator (t-PA). Despite the presence of ample t-PA, ligneous samples were essentially devoid of fibrinolytic activity. In contrast, neither proteins nor t-PA could be detected in mucoid samples when fractionated by 7.5-15% SDS-PAGE or analyzed by fibrin zymography, respectively. Despite the absence of t-PA, mucoid samples were replete in fibrinolytic activity. This activity was plasminogen independent, heterogenous and inhibited by PMSF. Degradation profiles suggested that this activity represented in part alpha-chymotrypsin, consistent with this patient's treatment regime, as well as plasmin, elastase and an unidentified neutrophil-derived activity. Interestingly, ligneous samples contained both latent and activated forms of matrix metalloproteinase-9 (MMP-9), whereas mucoid samples contained predominantly activated forms of MMP-9. LC is characterized by defective fibrinolysis, despite the presence of ample t-PA and intact fibrin, and by an abundant mucoid thread which binds both endogenous and exogenous enzymes including serine protease(s) and collagenase(s). The implications of these results with respect to a role for exuberant mucus production or abnormal mucins in the development of a relative mucosal-site specific plasmin(ogen) deficiency is discussed.- - - - - - - - - - ranking = 1.7380197505831keywords = ocular, eye (Clic here for more details about this article) |
10/208. Linear IgA bullous disease limited to the eye: a diagnostic dilemma: response to intravenous immunoglobulin therapy.PURPOSE: To report on a diagnostic dilemma and treatment challenge in a patient with chronic cicatrizing conjunctivitis without involvement of skin and other mucous membranes persisting for 6 years and not responding to topical and systemic steroids. DESIGN: Interventional case report. methods: We performed direct immunofluorescence of the conjunctiva with fluorescein-conjugated rabbit antihuman antibodies against immunoglobulin a, G, and M, complement 3 component, and fibrinogen. To investigate the presence of circulating antibodies in patient's serum, indirect immunofluorescence using normal human conjunctiva, normal human skin, and monkey esophagus as substrate was done. In addition, we did immunoblot analysis using normal human epidermis as substrate to determine the molecular weight of an antigen. The patient was treated with intravenous immunoglobulin (IVIg). The correlation between the titer of circulating antibodies and the activity of conjunctival inflammation at various intervals during the course of IVIg therapy was demonstrated by immunoblot assay with serial dilutions of the patient's serum. The highest dilution at which the binding was visible was considered the titer. RESULTS: Direct immunofluorescence of the conjunctiva and indirect immunofluorescence with both salt split skin and conjunctiva as substrate disclosed linear deposition of immunoglobulin a (IgA) at the epithelial basement membrane. Immunoblot analysis demonstrated the presence of IgA circulating antibodies in patient's serum directed against a 97kDa protein in human epidermis. A continuous decrease in the titer of these antibodies correlating to improvement of clinical symptoms was observed during IVIg therapy. CONCLUSIONS: Use of a nonconventional diagnostic tool (immunoblot analysis), in addition to conventional immunohistologic studies, might be helpful in establishing the diagnosis of patients with chronic cicatrizing conjunctivitis. On the basis of results of these laboratory tests and clinical presentation, we believe that this patient has linear IgA bullous disease limited to the eye. IVIg therapy decreased the titer of circulating antibodies and induced a remission in this patient.- - - - - - - - - - ranking = 1.3099012470846keywords = eye (Clic here for more details about this article) |
