This study involves observing and comparing Intraocular Pressure and Optic Nerve Sheath Diameter in steep trendelenburg position. Both observations will be done in same patient over the surgical duration.
Steep trendelenburg position is required for various robotic surgical procedures like hysterectomy, radical prostatectomy etc. Both Intraocular Pressure and Optic Nerve Sheath Diameter are found to get increased while in this position.
Intraocular Pressure will be measured by schiotz tonometer over an hourly interval whereas Optic nerve sheath diameter will be measured with use of ultrasound using a probe of 7.5 Mega hertz. Both values will be measured in both the eyes and will be compared statistically to find any correlation which may exist between the two.

| correlation between rise of intraocular pressure and optic nerve sheath diameter | Intraocular pressure will be measured using schiotz tonometer whereas optic nerve sheath diameter will be assessed using ultrasound in same patient at same intervals. This will give us both the values of intraocular pressure and optic nerve sheath diameter at same time which as per previous studies increases and are statistically significant. After compilation of results it will be analyzed that whether both values increases in a correlated manner or not which will give us our results that whether increase of one value can tell the increase of other value. | 9 months |
