Wpływ spontanicznego tylnego odłączenia ciała szklistego na resorpcję obrzęku plamki w retinopatii cukrzycowej w przebiegu cukrzycy typu II

Introduction
To establish the influence of posterior vitreous detachment on development and resolution of diabetic macular edema in NIDDM. To asses the posterior vitreous detachment role in argon laser treatment of diabetic macular edema. Material and methods: Retrospective study.

Material and methods
68 eyes of 36 patients were involved into the study, 52 eyes (76,5%) with macular edema and 16 eyes (23,5%) without macular edema. Posterior vitreous detachment (PVD) was present in 62,5% of cases without macular edema, and only 30,77% of cases had macular edema.

Results
Laser treatment applied in accordance to general standards cased resolution of macular edema in all cases with posterior vitreous detachment. In group with no spontaneous posterior vitreous detachment, macular edema resolved only in 19,23% of cases.

Conclusions
Diabetic macular edema is less common in eyes with spontaneous posterior vitreous detachment. This observation shows, that not only vascular factor but also vitreo-macular tractions are responsible for macular pathology in diabetic macular edema. The efficacy of standard argon laser treatment depends also on vitreo-macular relation – presence of PVD, and is more sufficient in eyes with posterior vitreous detachment.
