Abstract Details

Purpose:

Assessment of changes in the central macular thickness (CRT), choroidal thickness (CT) and the axial length (AXL) after successful glaucoma surgery: trabeculectomy vs mini ExPress device implantation.

Setting:

Departament of Ophthalmolpgy, Mediacal University of Białystok,Poland

Methods:

46 eyes with unregulated open-angle glaucoma despite maximal-tolerated medical therapy were qualified for surgery. There were 25 eyes and 21 eyes in the ExPress and the Trabeculectomy group, respectively. The following criteria were assessed: intraocular pressure (IOP), corrected distance visual acuity (CDVA), central macular thickness, choroidal thickness and the axial length. Postoperative assessments took place on the 3rd month after surgery.

Results:

After 3 months of observation, the reduction in IOP was similar in both groups: the average IOP in the ExPress group reduced from 25.1 ± 9.3 to 18.4 ± 3 mmHg (P< 0.05), and from 26.1 ± 11.5 to 16.8 ± 3.6 mmHg in the Trabeculectomy group(P<0.05). CT and CRT increased in both groups after surgery (164,18 ± 21.4 µm vs 161,77 µm ± 19.3 µm) and (227,79 ± 15,1 µm vs 232,57 ±13.2µm) (P<0.05) respectively. AXL declined in both groups (23,33 mm vs 23,19 mm). We did not find any significant differences in the studied variables after surgery between the groups.

Conclusions:

Both methods are effective for the surgical treatment of open-angle glaucoma. They have similar impact for CT,CRT and AXL postsugery changes.
