Graves’ disease is the most common thyroid abnormality associated with thyroid eye disease. Aim: This study was conducted for the profile of ocular manifestation in Thyroid Eye Disease (TED). Methodology: A cross-sectional study of 117 cases of thyroid dysfunction was carried out at BP Koirala Institute of Health System, out of which 84 (71.79%) cases had ocular manifestation. They were evaluated and analyzed in detail and the characteristics documented included patient’s demography, ocular and systemic history and as well as ocular examination and some of the systemic and laboratory findings. Results: In this study, mean age of presentation of TED was 39.7 years. 59 patients were female and 25 were male. The maximum patients of both sexes were in the fourth decade of their lives. The common lid signs were lid retraction and lid lag. Proptosis was seen in 33.3% of cases out of which 68% had bilateral proptosis. Corneal ulcer was seen in 7.1% and optic neuropathy in 1.2% of cases. In 27.3% of cases there was elevation of IOP. Dry eye was seen in 61.9% of cases and POAG seen in 8.3% of cases. In the study population 75% were hyperthyroiditic, 16.7% were hypothyroiditic and 8.3% were in euthyroid state. Conclusion: Female was more commonly affected. The maximum number of patients of both sexes was in the fourth decade of their lives. Hyperthyroidism patient had greater chance of ocular manifestation.展开更多

Eleven concurrent paraffin specimens of thyroid-associated ophthalmopathy(TAO) composed the control group. In situ hybridization was performed to detect EBERs. Immunohistochemistry was employed to detect CD3,CD20,Vimentin,and smooth muscle actin(SMA),and the positive rate,types of positive cells,and distribution and location of EBERs were evaluated.RESULTS: The positive expression rate of EBERs was 47.5%(19/40) in the IOIP group,which was significantly higher than that in the TAO group [0(0/11),P=0.011]. In the IOIP group,the lymphocyte infiltrative subtype,fibrotic subtype,and mixed subtype exhibited EBER-positive rates of 57.1%(12/21),12.5%(1/8),and 54.5%(6/11),respectively,and no significant differences were found between these subtypes(P=0.085). Positive signals of EBERs were mainly present in medium-small lymphocytes between or around follicles and in the nuclei of activated immunoblasts(14/19).CONCLUSION: The positive rate,types,and distribution of EBER-expressing cells in IOIP have been documented.These findings are conducive for a better understanding of the underlying mechanisms of Epstein-Barr virus infection in IOIP pathogenesis.展开更多
