Purpose:
To evaluate the intraocular pressure (IOP) variations which occur during and after strabismus surgery.
Method:
We measured the IOP in 34 eyes of 20 pediatric patients undergoing primary strabismus surgery under general anesthesia. Measurements were performed by the Tono-Pen (Mentor O&Q Inc. Norwell, MA) prior to surgery, immediately after suturing of the conjunctive, and 1 week and 4 weeks after surgery. All patients received the same local antibiotics and steroid solutions postoperatively.
Results:
IOP decreased from baseline to the end of surgery by a mean of 8.26 +/- 1.8 mmHg and increased from baseline to 4 weeks after surgery by a mean of 3.6 +/- 1.8 mmHg. Thirty-eight percent of the eyes had an IOP of 21 mmHg or more during the postoperative period.
Conclusion:
IOP variations are prevalent during and after strabismus surgery. Careful postoperative measurements are recommended in order to identify individuals who may be prone to iatrogenically increased IOP.
