The use of micropulse laser in patients with diabetic macular edema at the department of ophthalmology, faculty hospital Hradec Králové
Abstract
The paper describes the results of diabetic macular edema (DME) therapy with a micropulse laser with a wavelength of 577 nm. DME is the most common cause of decreased vision in patients with type 2 diabetes mellitus (DM).
A group of 63 eyes were observed for more than 1 year. Most patients had first type of diabetes mellitus (36), 3 patients had type 1.
The mean value of glycated hemoglobin (HbA1c) in the group was 66.8 mmol/mol, max. value was 100 mmol/mol. At the end of the annual follow-up period, we documented the improvement of the best corrected visual acuity (BCVA) by at least 5 letters of ETDRS optotype in 20 eyes and stabilization in 25 eyes (45 eyes, 71% of the set).
In 18 eyes there was a decrease in BCVA by more than 5 letters of ETDRS optotypes. In the monitored period of one year, we also found that, on average, the BCVA fell from an input of 62 letters to 61.1 letters (p> 0.05).
After one year, the central retinal thickness (CRT) decreased by 63 μm in diameter from 442 μm to 379 μm (p = 0.0124). In our study, after an annual evaluation, we have shown almost 3/4 of the total number of eyes to improve and stabilize NKZO in patients with DME treated with a micropulse laser.
A statistically significant decrease in macular edema was achieved in all eyes of the monitored set. The results confirm the stabilization of the finding after laser treatment.
