The Serum Angiotensin Converting Enzyme and Lysozyme Levels in Patients Non-infectious and Infectious Uveitis
The Serum Angiotensin Converting Enzyme and Lysozyme Levels in Patients Non-infectious and Infectious Uveitis
This study evaluates the significance of differences in serum angiotensin converting enzyme
 and lysozyme levels of patients with ocular involvement of other autoimmune inflammatory and
 infectious diseases.
Increased serum levels of angiotensin converting enzyme and lysozyme are considered as
 inflammatory markers for diagnosis of sarcoidosis which is an autoimmune inflammatory
 disease. Sarcoidosis, ankylosing spondylitis and Behcet's disease are the most common
 autoimmune inflammatory diseases involving the eye.

 Elevated serum angiotensin converting enzyme levels have also been reported in tuberculosis.
 Syphilis and tuberculosis are the most common infectious diseases involving the eye.
Inclusion Criteria:

 -  Subjects have ocular inflammation diagnosed as sarcoidosis, ankylosing spondylitis,
 behcet's disease

 -  Subjects have ocular infection diagnosed as tuberculosis and syphilis

 -  Subjects have refractive errors only

 Exclusion Criteria:

 -  Subjects using ACE inhibitors, systemic steroids, immunosuppressive or
 immunomodulatory therapies
