RESUMO
Purpose: To investigate the possible ocular biometric and keratometric changes in low and high degrees of simple myopia
Subjects of Methods: A sample of 60 myopic subjects their ages between 10 and 30 years recruited from the Makkah Eye Hospital in Khartoum. In this sample, 30 subjects with myopia < 3.00 D and other 30 subjects with myopia > 6.00 D. Auto keratometry and A-scan biometry were measured from two eyes of each subject
Results: Subjects with high myopia have longer axial length [AL] [P < 0.0001] compared to low myopic subjects. No significant difference found in front surface corneal power or type of corneal astigmatism between the two groups
Conclusion: Like previous studies myopia mainly develops with increases in AL of the eye rather than optical changes in cornea or lens
RESUMO
Purpose: The aim of the study was to determine the frequency and pattern of eye diseases among patients attending the eye clinics of Makah Eye Hospital, Khartoum, Sudan
Methods: A retrospective study involved all the new cases presenting to the outpatient department of the hospital over a 22-month period from January 2012 to October 2013. Patients were examined by optometrists/ophthalmologists through routine examination using the Snellen's chart, refraction, tonometry, slit-lamp examination of the anterior segment, and fundus examination
Results: A total of 64,529 patients were seen during this period with a male to female ratio of 1:1.1. The most common eye diseases were cataract, allergic conjunctivitis, infective conjunctivitis, refractive disorders, and glaucoma
Conclusion: The pattern of eye diseases observed in Makah Eye Hospital was similar to other reports from developing world and such study will be helpful in planning, management, and prevention of blindness
RESUMO
Background: The prevalence of Hepatitis [type B and C] and Human Immunodeficiency Virus [HIV] is high in Sub-Saharan region. This creates an attentive risk of transmission among medical staff and their patients. The aim of this article is to appraise possible changes of transmission of those diseases among theater staff and ophthalmic patients
Objectives: To determine the proportion of patients for cataract surgery who might be carriers to hepatitis and/or HIV
Methods: A total of 4848 patients registered for cataract surgery between May and October, 2012 at Makkah Eye Complex, Khartoum, Sudan; were serology screened for hepatitis [type B and C] and HIV. There were 336 patients found to be positively infected by one or more of these diseases
Results: During study period the prevalence rate of total of these viral diseases was 6.93% [336/4848] of which 0.53% [26/4848] patients were HIV positive, 4.5% [227/4848] were positive for hepatitis [B] and 1.9% [95/4848] were positive for hepatitis [C]
Conclusion: There is a negligible but real risk of transmission of HIV and hepatitis during cataract surgery. Pre-operative screening of all patients going for major ophthalmic surgery may be desirable to protect theater staff and patients
