Background:
The frequency and spectrum of ophthalmologic manifestations in patients with inflammatory bowel disease (IBD) has been reported to vary among studies; however, rare and silent manifestations have not been extensively studied.
Methods:
This was a prospective study of 60 patients diagnosed with IBD who underwent full ophthalmologic examination, including visual acuity, slit lamp examination of the anterior segments, intraocular pressure, and fundus examination accompanied by color photography. Thirty-seven (61,7%) patients were diagnosed with ulcerative colitis (UC) and 23 (38,3%) with Crohn's disease (CD). Data from 276 control individuals were used for the determination of the prevalence of dry eye in our area.
Results:
Ophthalmologic manifestations were diagnosed in 26 (43%) patients (14 UC, 12 CD; 12 males and 14 females). Conjunctivitis was diagnosed in 1 patient (CD), episcleritis in 2 patients (UC), and iridocyclitis in 3 (CD). Fundus examination showed 1 patient (CD) with unilateral choroiditis, 1 (UC) with retinal vasculitis, and 1 (CD) with optic neuritis. Retinal pigment epithelium disturbances (RPED) were present in 3 patients (1 CD, 2 UC) and 2 had serous retinal detachment. In total, 13/60 patients (22%) had dry eye compared with the 11% prevalence in controls. Eight patients developed glucocorticosteroid-induced cataracts, 2 of them treated surgically.
Conclusions:
This study demonstrated the prevalence of the spectrum of ophthalmologic manifestations in the IBD population, including some rare and silent findings that may merit consideration and early intervention.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
