Zusammenfassung: | Diabetic retinopathy is one of most important complications of diabetes mellitus that can be treated by Nd : YAG laser. Laser is used in ophthalmic practice for photocoagulation and photo disruption.
The purpose of this study is to evaluate changes in immunological, hematological and biochemical values after treatment of diabetic retinopathy by laser. Blood samples from 10 patients suffering from diabetic retinopathy were taken before and after laser treatment to coagulate retina to prevent leakage and hemorrhage to avoid deterioration of vision. In group one (4 patients = 40 %), blood tests were done one day after treatment. In group two (6 patients = 60 %) tests were done 7 days after treatment with laser. The study showed no clear changes in the values of biochemical tests (except glucose is already high) and hematological tests (except PT, PTT, clotting time and bleeding time for those patients taking l00mg acetylsalicylic acid or warfarin) after irradiation with laser, probably because that main organs that affecting these tests or the elements that involve in these tests have not been irradiated directly. The main changes were in immunoglobulin values which increased as noticed in both groups, because all light induced biological effects depend on the parameters of irradiation, the results suggest that the laser irradiation may play two principal roles in immunological changes. First, is stimulation of cellular? proliferation, and stimulation of cellular differentiation that is responsible for different types of immunoglobulin. The other suggestion is that laser is acting as a triggering factor which induces systematic effects through the circulation when laser interacts with living cells so it has systemic effects through circulating blood.
إن آفة شبكة العين السكري هي من المشاكل المهمة التي تحدث في مرضى داء السكري التي من الممكن معالجتها باستخدام الليزر النيديميوم ياك. أن الهدف من هذه الدراسة هو تقييم التغيرات في القيم الدموية و الكيموحيوية و المناعية التي قد تحدث بعد أجراء المعالجة بالليزر. أخذت نماذج دم من عشر مرضى مصابين بآفة شبكة العين السكري قبل و بعد المعالجة بالليزر حيث أخذت النماذج بعد يوم واحد من المعالجة (من أربعة مرضى / مجموعة أولى) و بعد سبعة أيام من المعالجة (من ستة مرضى / مجموعة ثانية) حيث تبين أنه لا يوجد تغيير في قيم الفحوص الدموية و الكيموحيوية و قد يكون السبب بأن الأعضاء المسؤولة عن هذه القيم لم تشع بصورة مباشرة. و أن التغييرات قد حدثت في قيم الفحوص المناعية حيث ازدادت زيادة قليلة في المجموعة الأولى ما عدا في الحالة الأولى حيث كان |
