Abstract Details

Purpose:

To study the trend of intra ocular pressure in retinal detachment surgery with silicone oil tamponade.

Setting:

The study was conducted at Dr.R.P.Centre, AIIMS, a tertiary level hospital in New Delhi, India

Methods:

20 eyes of 20 patients who underwent Vitrectomy with silicon oil tamponade for non traumatic and uncomplicated retinal detachment were studied. After closure of surgical ports, the immediate post surgical IOP (isIOP) was measured on operating table with Perkins tonometer using aseptic precautions. Post-operative IOP was measured at Day 1, 7, 15, 30, 60, 90.

Results:

IOP recorded at Day 1 was significantly higher than the isIOP recorded on table (p<0.001). Out of the 20 patients studied, 12 patients had an isIOP < 10 mm Hg with the remaining having an isIOP > 10 mm Hg. Patients with isIOP< 10 mmHg maintained a lower IOP than those having isIOP> 10mm Hg throughout the post-operative period, requiring lesser number of anti glaucoma medications for a lesser duration. Also, patients with isIOP< 10 mmHg did not require any form of surgical intervention for silicon oil induced glaucoma. Two patients with isIOP> 10mm Hg required surgical intervention; one required trabeculectomy and the other required partial silicon oil removal for IOP control.

Conclusions:

A simple technique such measurement of immediate post surgical IOP may help predict long term IOP trends and may help achieve optimal control of IOP in the post-operative period. Ensuring isIOP < 10m Hg after closure of surgical ports prevents overfill of silicon oil and also decreases the occurrence of silicon oil induced glaucoma.and need for further medical and surgical intervention.
