SUMMARY
Objective: To measure some ocular parameters in inflammatory bowel disease and evaluate whether there are any differences between the measurements obtained from the patients and healthy subjects.Methods: Thirteen patients with inflammatory bowel disease referred from the gastroenteroloji clinic and 14 control subjects selected from the individuals with minor complaints who admitted the ophthalmology outpatient clinic were included in the study. Average and segmental retinal nerve fiber layer thickness in four quadrant, average and sectoral ganglion cell inner plexiform layer thickness in in six guadrant, foveal and parafoveal vessel density in four quadrant, optic nerve head parameters, including rim area, disc area, horizontal cup-to-disc ratio, vertical cup-to-disc ratio, cup volume and additionally superficial/deep foveal avascular zone areas, choroid thickness, and central corneal thickness of the patients and controls were quantified using the swept-source optical coherence tomography. Results: All measurements taken from the patients with inflammatory bowel disease and controls showed a great similarity and did not differ statistically. Conclusion: Even though several inflammatory systemic diseases affect the eye and alter the particular structures, this study revealed that inflammatory bowel disease has no inluence on neural and vascular layers of the eye.
