A Comparison of Intraocular Pressures (IOP) During Prolonged Trendelenburg Positioning in Morbidly Obese and Thin Patients
Stopped early
Conditions studied: Intraocular Pressure Disorder
In brief
This study is to determine if there is a rise in eye pressure, when patients are placed in a position where the head is lower than the rest of the body during long surgeries.

Who can join
Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Subjects undergoing prolonged procedures (scheduled >3hr) in steep Trendelenburg position (eg. robotic prostatectomy, hysterectomy, cystectomy)
- Morbidly obese subjects: BMI ≥ 35 kg/m2
- Thin subjects: BMI ≤ 30 kg/m2
- Age 18-70
- ASA (American Society of Anesthesiologists) physical status classification I, II, or III
You may not qualify if…
- Known history of glaucoma
- Note:if initial IOP is noted to be >21mmHg (millimeters of mercury), patient will be excluded from study and an ophthalmology consultation will be obtained.Surgery will not be postponed.
- Recent use of IOP lowering topical ophthalmic agents
- Allergy to latex or proparacaine hydrochloride ophthalmic solution
- Patients with active corneal epithelial defects or history of recurrent corneal erosion
- Patients with underlying disorders that can directly increase intraocular pressure (thyroid eye disease, intra orbital tumors, orbital vascular malformation, Sturge-Weber disease, carotid or dural cavernous arteriovenous malformation, cavernous sinus pathology)
- History of corneal surgery, to include LASIK (laser-assisted in-situ keratomileusis)
- Any eye surgery within prior 1 month
