Abstract
Purpose: :
To assess the value of OCT retinal map in understanding the configuration of vitreomacular traction syndrome and evaluate its usefulness in enhancing postoperative outcome of vitreomacular traction syndrome by assisting decision making process during surgery.
Methods: :
reoperative OCT retinal map of 6 patients diagnosed with vitreomacular traction syndrome was obtained to gain understanding of three dimensional architecture of vitreomacular traction syndrome. 25 gauge needle was used to create an opening at the farthest site from the detached posterior hyaloid membrane near perifoveal region and pick forcep was inserted to separate attached fovea to make complete PVD and 25 gauge vitrectomy was performed.
Results: :
The postoperative foveal thickness decreased in all patients. The mean preoperative foveal thickness was 497um and it diminished to 187 um at postoperative 3 months. The average of best corrected visual acuity was 0.42 preoperatively when measured with snellen charts and it increased to an average of 0.73 at postoperative 3months with a mean increase of 3.1 snellen lines. Foveal pit was formed in 5 patients (83.3%) and no postoperative complications were reported.
Conclusions: :
OCT retinal map is valuable in understanding the contour of vitreomacular traction syndrome. Planning surgical approach preoperatively with assistance of OCT retinal map would enhance the surgical outcome and minimize postoperative complications.
