ABSTRACT
BACKGROUND:
Inflammatory bowel disease is a systemic inflammatory disease classified as Crohn disease or ulcerative colitis. It could present extra intestinal findings, such as fever, weight loss, arthralgia, mucocutaneous lesions, hepatic, renal and ophthalmological involvement. Among ophthalmological findings, posterior segment findings are present in less than 1% of patients with inflammatory bowel disease, however, these findings could bring definitive visual impairment.
OBJECTIVE:
Our study objective was to evaluate ocular posterior segment findings is patients with inflammatory bowel disease, through retinal mapping, color fundus retinography, optical coherence tomography (OCT) and OCT angiography, and compare our results to literature.
METHODS:
We evaluated eighty patients with inflammatory bowel disease through complete ophthalmological examination and posterior segment assessment. Color fundus retinography, OCT and OCT angiography was performed with Topcon Triton (Topcon® , Tokyo, Japan). Macula and posterior pole were evaluated with binocular indirect ophthalmoscopy and fundus biomicroscopy.
RESULTS:
Participants mean age was 44.16 years (18.08-68.58), 28 (35%) male patients and 52 (65%) female patients. Thirty-five (44%) with diagnosis of Crohn disease, 41 (52%) patients with diagnosis of ulcerative colitis and 3 (4%) had non-conclusive Crohn disease or ulcerative colitis classification. We found abnormal exams in 21 (26.25%) patients.
CONCLUSION:
Our study found similar prevalence of ophthalmological posterior segment commitment compared to previous literature prevalence. The findings were predominantly unrelated to inflammatory bowel disease, rather than primarily related to it. The most prevalent, and non-previous reported, finding was increased arteriolar tortuosity, probably occurs due to systemic vascular impairment in inflammatory bowel disease.
