Purpose:
|
To introduce a simple and practical method for detecting viterectomy infusion line position in hazy media.
|
|
Methods:
|
The position of the infusion cannula was evaluated before and during viterectomy by the use of light pipe inserted partially into the cannula and the colour of transmitted light into vitreous cavity In 17 eyes of 17 patients with hazy media. . Dark red or brownish colour was considered as suprachoroidal placement and bright -whitish colour as correct position of the cannula tip.
|
|
Results:
|
In 13 patients the position of cannula considered as correct by using this method and viterectomy was done without any infusion line related complications. In two cases the incorrect placement of infusion cannula was confirmed with this technique and the cannula was reinserted and repositioned. In two cases secondary slippage of canulla in suprachroidal space was detected by the use of this method during viterectomy and another cannula was tried in another position.
|
|
Conclusion:
|
Using the colour of light pipe inserted partially into the cannula is a safe and simple method for evaluating the position of infusion line in the eye.
