    Tear Quantity and Outer Eye Disorders in the Patients with Chronic Renal Failure Undergoing Hemodialysis
    (Graduate College - Alneelain university, 2017-12) Zeinab Altyeeb Osman, Madiha Sid Ahmed Ali
    Aim: To evaluate the tear quantity and outer eye disorders in the patients with chronic renal failure who undergoing hemodialysis. Material and Methods: A comparative cross sectional hospital based study was done in Khartoum State at Omdurman Military Medical Hospital and Abdulrahman Salih Sabderat Centre in the period from April to June 2017. Schirmer test paper was used to evaluate the tear quantity, stop watch was used to adjust time when assessing the tear quantity, outer eye was examined by a torch and hand held magnifier, the collected data was analyzed by SPSS 20. Results: A total of 100 subjects (100 eyes) was investigated, the study group were 50 patients with renal failure; 56% males and 44% females their age was ranged between (20-45) with mean 33.18±7.34 years, while the control group(50 subjects) 38% of them were males and 62% were females. Their age range was (20-44) with a mean 30±8.94 years. Sixty two percent of the patients with renal failure were complain of different symptoms (itching 45%, blur in vision 22%, discharge 20%, unable to see at night 2%, lacrimation 22%, redness 4%, ocular pain 2%, headache 2%), 86% had outer eye disorders (pterygiumwithredness2%, redness 2%, redness and yellow conjunctiva 32%,yellow conjunctiva50%). There was a significant difference when comparing the mean of tear quantity between study group 16.3±8.75 and the control group 17.7±6.40, P value 0.000. Conclusion: Chronic renal failure disease leads to eye dryness and outer eye disorder. Hence proximate observation is necessary for those patients.

    Tear quantity in thyroid dysfunction
    (Graduate College - Alneelain university, 2017-12) Amna AbdAlla, Madiha Sid Ahmed
    Aim: To measure the tear volume in thyroid dysfunction patients and to estimate the vision and outer eye. Material and Methods: This is a cross sectional hospital based study, it was done at Omdurman military hospital and Al Ribat university hospital in the period from August to December 2016.One hundred and thirty patients with thyroid dysfunction (80 hyperthyroidism and 50 hypothyroidism) were included in this study. The vision was estimated by Snellen’s chart, outer eye was investigated by torch and hand held magnifier and Schirmer paper test was used to asses tear quantity. Results: Eighty four percent of hyperthyroidism and 88.75% of hypothyroidism were females. Hyperthyroidism patients represent 61.54%; 20% of them showed exophthalmos, vision mean was0.84±0.25 (range 0.1-1.00). The patients with hypothyroidism (38.46%) had slightly better vision with mean 0.92±0.19 and range 0.1-1.00. Tear quantity was more reduced in hyperthyroidisms patients (mean 10.8±5.8and range: 3-35mm)than in hypothyroidisms (mean 12.8±6.7mm and range: 4-35mm).Conclusion: Regular ocular examination is recommended for patients with thyroid dysfunction to save their eyes. الملخص الهدف: أجريت هذه الدراسة لقياس كمية الدموع عند المرضى المصابين بخلل في وظائف الغدة الدرقية وتقييم النظر واجزاء العين الخارجية. الطرق والوسائل: هذه الدراسة المقطعية اجريت في مستشفى السلاح الطبي ومستشفى الرباط الجامعي في المدة من اغسطس حتى ديسمبر2016 شملت هذه الدراسة مئة وثلاثون مريض مصاب بخلل في وظائف الغدة الدرقية (80 فرط نشاط الغدة الدرقية و 50 قصور الغدة الدرقية). تم تقييم كل من النظر باستخدام لوحة سنلين , أجزاء العين الخارجية باستخدام البطارية والمكبر اليدوي واختبار الشيرمر لقياس كميه الدموع. النتائج: اربعة وثمانون في المئة من المرضى المصابين بنشاط في الغدة الدرقية و 88.75 % من المصابين بقصور الغدة الدرقية كانوا نساء. مرضى نشاط الغدة الدرقية يمثلون 61.54%، 20%منهم مصابون بجحوظ العين. الوسط الحسابي لحدة النظر كان لديهم0.84±0.25.اما المرضى المصابين بقصور الغدة الدرقية (38.46%) كانوا افضل قليلا من ناحية حدة النظر (الوسط الحسابي0.92±0.19). كمية الدموع كانت اقل عند المرضى المصابين بفرط نشاط الغدة الدرقية (الوسط الحسابي 10.8±5.8ملم، المدى من 3-35 ملم) مقارنة بمرضى القصور في الغدة الدرقية (الوسط الحسابي12.8±6.7 ملم في المدى من 4-35). الخلاصة: يوصى بالفحص المنتظم للعين للمرضى المصابين بخلل في وظائف الغدة الدرقية للحفاظ علي سلامة اعينهم.
