The mechanisms of variation of intraocular pressure (IOP) during abdominal surgical interventions it is not completely clear and its result on the recovering patient may vary from benign alterations to disabilities. This review aims to identify the most important triggers and its impact of IOP along with individual risk factors during the perioperative period of abdominal surgeries. International literature is providing limited data on this topic. We reviewed 9 studies using PubMed, Scopus, and Web of Science as database. From the multitude of effects and implications that abdominal surgery has onto the physiology of eyeball, the highest impact was linked to the positioning of the patient, induction of anesthesia, perianesthetic events such as intubation and extubation, type of anesthesia and anesthetic used, pneumoperitoneum induced in laparoscopic surgeries and its contribution to the alterations of ocular parameters which are increasing the risk of ocular events. In addition to this, the association of individual risk factors as well as the pre-existing of ophthalmologic diseases may have severe consequences onto the visual function.

The human body can be envisioned as a high-performance machine that operates on the principle of "gears". As a consequence, any disorder at a certain level might lead to imbalances in other areas, which are sometimes difficult to detect and measure. One such relationship between two seemingly unrelated systems is that of abdominal surgery and intraocular pressure. The literature on this subject is poor, but available research suggests the occurrence of a change in intraocular pressure in the context of abdominal surgery. The present study analyzed the variation of intraocular pressure for two groups of patients who underwent classical or laparoscopic cholecystectomy. The present research is based on a prospective, non-interventional, observational, descriptive study, carried out in the IIIrd General Surgery Clinic of the University Emergency Hospital, Bucharest. The study included patients who underwent abdominal surgery during January 2018 - December 2019. The study gathered a total of 67 patients, separated into two groups: 52 patients who underwent laparoscopic cholecystectomy and 15 who underwent open cholecystectomy. No definite relationship between intra-abdominal pressure and intraocular pressure was found in the analyzed group, probably due to the small sample size, but further research is encouraged.

A 20 years old female presented for a routine eye examination. Her best corrected visual acuity (BCVA) was OU - 20/20 Snellen chart. Fundoscopy of the right eye revealed a massive optic disc coloboma with no other associated abnormalities. Fundoscopy of the left eye revealed a normal eye fundus. Optic nerve coloboma is a congenital condition caused by incomplete closure of embryonic fissure. It usually occurs bilaterally, autosomal dominantly inherited, or sporadic cases. Serous macular detachment and visual field loss can be frequently observed in this condition. It can also be associated with other colobomas (lens, cilliary body and choroid), microphtalmos, retinal dysplasia, or can be part of systemic anomalies like Aicardi syndrome, Meckel syndrome and CHARGE association, with poor visiual prognosis. Subjects with isolated optic nerve coloboma, with no other associated abnormalities, like this case, can have excellent visual prognosis.
