With Universal eye speculum, the value for the right eye was 25.51+-3.02, and for the left eye it was 25.78+-3.64.
Conclusion: Barraquer wire speculum caused less increase in intraocular pressure compared to the Universal eye speculum.
Keywords: Barraquer wire speculum, Universal eye speculum, Intraocular pressure.
IOP was again measured with Barraquer wire eye speculum inserted in the eye in group 1, and with Universal eye speculum in group 2.
Paired Sample t-test was used to compare the variable of baseline IOP with Barraquer speculum and Universal eye speculum.
With Barraquer wire speculum, the value for the right eye was 22.21+-4.99, and that of the left eye was 23.08+-5.41.
Lid retractors may press the eye and cause bulging of the intraocular contents.11 To reduce this extraocular pressure effect, loosening the speculum and eyelid sutures would help.
The study, therefore, recommended that a method of eyelid retraction which allows adjustment is to be preferred, and that specula which do not allow this, such as the Barraquer speculum, are not to be recommended.12 But the current study found that the Barraquer speculum caused approximately 7mmHg increase in IOP compared to the Universal speculum which resulted in around 10mmHg.
When designing the DySIS speculum, our key requirement was safety.
