Some diseases of the orbit and the optic nerve are associated with an increased orbital compartment pressure (OCP), e.g., retrobulbar hemorrhage or thyroid eye disease. Our aim was to review the literature on the different approaches to assess OCP. Historically, an assessment of the tissue resistance provoked by the retropulsion of the eye bulb was the method of choice for estimating OCP, either by digital palpation or with specifically designed devices. We found a total of 20 articles reporting direct OCP measurement in animals, cadavers and humans. In nine studies, OCP was directly measured in humans, of which five used a minimally invasive approach. Two groups used experimental\/custom devices, whilst the others applied commercially available devices commonly used for monitoring the compartment syndromes of the limbs. None of the nine articles on direct OCP measurements in humans reported complications. Today, OCP is mainly estimated using clinical findings considered surrogates, e.g., elevated intraocular pressure or proptosis. These diagnostic markers appear to reliably indicate elevated OCP. However, particularly minimally invasive approaches show promises for direct OCP measurements. In the future, more sophisticated, specifically designed equipment might allow for even better and safer measurements and hence facilitate the diagnosis and monitoring of orbital diseases.<\/jats:p>","DOI":"10.3390\/diagnostics12061481","type":"journal-article","created":{"date-parts":[[2022,6,17]],"date-time":"2022-06-17T01:48:12Z","timestamp":1655430492000},"page":"1481","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Assessment of Orbital Compartment Pressure: A Comprehensive Review"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5211-7855","authenticated-orcid":false,"given":"Tim J.","family":"Enz","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, University of Basel, CH-4031 Basel, Switzerland"},{"name":"Lenzburg Eye Clinic, CH-5600 Lenzburg, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Tschopp","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Cantonal Hospital Aarau, CH-5001 Aarau, Switzerland"},{"name":"Department of Ophthalmology, Inselspital, University of Bern, CH-3010 Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"441","DOI":"10.1016\/j.survophthal.2009.04.005","article-title":"Orbital compartment syndrome: The ophthalmic surgical emergency","volume":"54","author":"Lima","year":"2009","journal-title":"Surv.
