Objective: We measured the thickness of the retina of patients with clinical significant macula edema with OCT before and after laser surgery. To judge is the behavior of the thickness of the retina and the connection between thickness and visual acuity.
Methods: 25 patients were measured before focal laser therapy and 7 weeks as soon as 3 months after therapy the thickness of retina with OCT by Zeiss / Humphry - Systems. Visual acuity was measured at all times. The ALC (green) occurred with focal laser.
Results: At the beginning and at the and of the study most of the data was at ca. 375 µm thickness of retina. A discreet decrease of thickness was recognized 7 weeks after laser therapy. At the last measurement, it increased again. Observing the differences between the thickness after 3 months and the thickness before therapy reveals a minimal decrease of the thickness. The thickness of the retina in the course of the study shows no significant change. The view is for the point of center. All three times place most of the visual acuity data around 0,7. Throughout the course, an increase in the thickness of the retina is always combined with a decrease of visual acuity. A decrease of the thickness of retina is shown only by constant and by an improvement of 0,2 visual steps. An improvement of visual acuity by all 25 patients (visual acuity between 0,1 - 1,25 ) is not significant.
Conclusion: Optically Coherence Tomography is suitable for observation of the development of the clinical significant macula edema. The retina tends to increase. A clear connection between thickness and visual acuity doe not exist.
