PurposeTo explore the effect of time on grading corneal fluorescein and conjunctival lissamine green staining in dry eye disease (DED).MethodsPhotographs of 68 subjects with non-Sjogren's DED (nSS DED) and 32 with Sjogren's DED (SS DED) were taken of corneal fluorescein staining, then conjunctival lissamine green staining every 30 s for at least 5 min. Photographs of one randomly selected eye were then randomly ordered and graded on a scale from 0 to 5 (severe staining) by two clinicians, masked to both site and subject. The average time required to reach the maximum grade of staining (Gmax) was calculated.ResultsThe median time (upper and lower quartiles) to corneal fluorescein Gmax was 2.6 (1.3–5.3) minutes for nSS DED and 3.8 (2.6–5.4) minutes for SS DED, a statistically significant difference (Mann Whitney U test, p = 0.018). In contrast, the median time to the Gmax for lissamine green staining of the nasal and temporal conjunctiva was 0.5 (0.5–1.1 nasal, 0.5–0.8 temporal) minutes for nSS DED and 0.5 (0.5–0.8 nasal, 0.5–0.5 temporal) minutes for SS DED subjects, which was not statistically significant (p ≥ 0.383).ConclusionsThe time required to reach the maximum grade of corneal fluorescein staining, but not conjunctival lissamine green staining, varied widely and was significantly longer in subjects with Sjögren's Syndrome. Early observation of corneal fluorescein staining can lead to under-grading, which may impact the diagnosis and assessment of treatment in DED. Further study of the best time to assess corneal fluorescein staining in various DED populations is warranted. 相似文献

Patients with conjunctival cicatrizing disease may develop lacrimal obstruction. Little is published on lacrimal obstruction as the presenting feature of otherwise asymptomatic cicatrizing conjunctival disease. The records of all patients presenting between 1994 and 2015 with lacrimal obstruction found to have cicatrizing conjunctival disease were reviewed. Demographic details, clinical findings, disease progression and treatment were analyzed. Thirty-five patients (25 female), aged 43–91 years (median 74, mean 71.3 years) had epiphora and a mild conjunctival cicatrizing process. Nine patients had onset of epiphora after cataract surgery. All except one patient had obstruction of the proximal lacrimal system (punctum and/or canaliculus). In 14 cases, the obstruction was unilateral (both puncta or canaliculi), with one progressing to bilateral obstruction after 11 years. In 19, all 4 puncta or canaliculi were obstructed. Two patients had unilateral nasolacrimal duct obstruction; one developed contralateral canalicular obstruction 2 years later. Conjunctival biopsies were obtained in 19 of 35 cases (54%), and OCP immunohistochemistry was positive in 7/19 (37%). All other biopsies showed chronic inflammation. Two patients had lichen planus. In follow-up (range 0.1–11 years, mean 3.2 years), 2 patients’ conjunctival disease progressed mildly, and 3 progressed moderately, with 2 of these 5 having positive OCP immunohistochemistry, and 1 having lichen planus. Patients with conjunctival cicatrization may present with lacrimal obstruction, usually punctal or canalicular. Conjunctival disease is usually mild and non-progressive, but patients should be monitored for disease progression. 相似文献

Tumors of the Ocular Surface clinically manifest with a very wide spectrum and include several forms of epithelial, stromal, caruncular, and secondary tumors. As a group, these tumors are seen commonly in the clinical practice of a comprehensive ophthalmologist, cornea specialist, and an ocular oncologist. This review is aimed to discuss the common tumors of the ocular surface and emphasize on their clinical diagnosis and appropriate management. 相似文献

OBJECTIVES:
To compare ocular surface changes induced via glaucoma treatment in patients using fixed combinations of prostaglandin analogues (travoprost, latanoprost and bimatoprost) with 0.5% timolol maleateMETHODS:
A prospective, multicenter, randomized, parallel group, single-blind clinical trial was performed in 33 patients with ocular hypertension or open angle glaucoma who had not been previously treated. The ocular surface was evaluated prior to and three months after treatment, with a daily drop instillation of one of the three medications. The main outcome measurements included the tear film break-up time, Schirmer''s test, Lissamine green staining, the Ocular Surface Disease Index questionnaire, impression cytology using HE and PAS and immunocytochemistry for interleukin-6 and HLA-DR. Ensaiosclinicos.gov.br: UTN - U1111-1129-2872RESULTS:
All of the drugs induced a significant reduction in intraocular pressure. Decreases in the Schirmer''s test results were observed with all of the drugs. Decreases in tear-film break-up time were noted with travoprost/timolol and latanoprost/timolol. An increase in the Lissamine green score was noted with travoprost/timolol and bimatoprost/timolol. The Ocular Surface Disease Index score increased after treatment in the travoprost/timolol group. Impression cytology revealed a significant difference in cell-to-cell contact in the same group, an increase in cellularity in all of the groups and an increase in the number of goblet cells in all of the groups. The fixed combinations induced an increase in IL-6 expression in the travoprost/timolol group, in which there was also an increase in HLA-DR expression.CONCLUSIONS:
All of the fixed combinations induced a significant reduction in intraocular pressure, and the travoprost/timolol group showed increased expression of the inflammatory markers HLA-DR and interleukin-6. All three tested medications resulted in some degree of deterioration in the ocular surface after three months of glaucoma treatment. 相似文献6.
Ocular melanomas comprise uveal and conjunctival sub-types, which are very different from each other. A large majority of uveal melanomas involve the choroid, with less than 10% being confined to the ciliary body and iris. They tend to metastasize haematogenously, almost always involving the liver. Therapeutic methods include various forms of radiotherapy, surgical resection and phototherapy, which are often used in combination. Conjunctival melanomas show many similarities to their cutaneous counterparts, often metastasizing by lymphatic spread. Treatment consists of excision of invasive melanoma with adjunctive radiotherapy and/or cryotherapy and topical chemotherapy for intra-epithelial disease. The management of patients with ocular melanomas demands a good understanding of the pathology of these tumours. Pathological examination of the tumour indicates the prognosis and hence the need for further investigation and treatment. The scope of the pathologist is enhanced thanks to advances in molecular biology. 相似文献

The main functions of the conjunctiva, an essential part of the ocular surface, are to maintain the equilibrium of the tear film and to protect the eye. Upon injuries, the prerequisite to successful ocular surface repair is conjunctival reconstruction. Tissue engineering techniques, including transplantation of autografts, amniotic membranes and numerous synthetic/natural materials, have been developed. However, none of these strategies is completely satisfactory due to lack of goblet cell repopulation, poor mechanical properties or non-standardized preparation procedure. Here, we cultured conjunctival epithelial cells on vitrified collagen membranes and developed a tissue equivalent for repairing damaged conjunctiva. Optimized vitrified collagen has superior mechanical and optical properties to previous biomaterials for ocular surface application, and its unique fibrillar structure significantly benefited conjunctival epithelial cell growth and the phenotypic development in vitro. In a rabbit model, vitrified collagen greatly promoted conjunctival regeneration with rapid re-epithelization, sufficient repopulation of goblet cells and minimized fibrosis and wound contracture, proved by gene expression analyses and histological staining. In conclusion, we have demonstrated the potential suitability of utilizing vitrified collagen-based tissue equivalent in ocular surface reconstruction. 相似文献

Schwannomas are benign, encapsulated, primary neurilemmal tumors composed of proliferating Schwann cells. Schwannomas are commonly seen in the orbit, but are rare on the epibulbar surface. Herein, we report a case of a 12-year-old boy who presented to us with a slow-growing painless subconjunctival mass in the left eye. There was no intraocular extension of the mass and intra-operatively, the mass could be clearly delineated and was excised off the underlying sclera. Histopathological examination of the mass showed typical features of schwannoma and immunohistochemistry helped to confirm the diagnosis. There was no recurrence of the lesion observed at follow-up 26 months after surgery. Here, we describe this uncommon tumor and review the available literature. Although rare, an epibulbar schwannoma should be considered in the differential diagnosis of an amelanotic, painless subconjunctival nodular mass. Excision of the lesion is the recommended treatment. 相似文献

Case report
A 35-year-old male patient with a large unilateral haemorrhagic conjunctival tumour lesion and another contralateral haemorrhagic conjunctival flat lesion associated with violaceous cutaneous macules on the extremities and angiomatous lesions in the upper gastrointestinal tract as initial clinical manifestation of HIV-related immunodeficiency. Cutaneous, gastric mucosal and conjunctival biopsy was consistent with Kaposi's sarcoma with complete remission after highly active antiretroviral therapy and systemic chemotherapy.Conclusion
HIV-related conjunctival Kaposi's sarcoma, even a large one, can have a good response to antiretroviral therapy and systemic chemotherapy without any additional topical eye treatment. 相似文献10.

AbstractPurpose: To correlate subclinical conjunctival inflammation and trabeculectomy results.Methods: Prospective case series of 28 patients with primary open-angle glaucoma (28 eyes) under topical anti-glaucoma medication who underwent trabeculectomy. During surgery, a sample from the inferior bulbar conjunctiva was collected and the expression of HLA-DR together with the presence of inflammatory cells was correlated with trabeculectomy outcomes after 24 months. Surgical success was defined as intraocular pressure between 6 and 20?mmHg irrespective of the use of anti-glaucoma medication.Results: Five patients missed follow-up visits and were removed from the study. Ten eyes (43.5%) were HLA-DR+, but no significant differences were observed between eyes with successful and failed surgeries (p?=?0.214). There was no significant association between the number of neutrophils and surgical outcomes (p?=?0.353).Conclusions: The presence of inflammatory cells and expression of the inflammation marker HLA-DR in the conjunctiva did not correlate with the prognosis of trabeculectomy in this study. 相似文献
