Purpose:
To characterize the course of uveitis in ulcerative colitis (UC) patients following colectomy and assess whether uveitis activity arises and/or persists independently of colonic disease.
Methods:
This is a retrospective case series from a tertiary uveitis referral center. Patients with non-infectious uveitis, a confirmed diagnosis of UC, and a history of colectomy were included. Clinical data were extracted, including demographics, ocular history, treatment regimens, and disease activity. Uveitis flares were defined as the presence of at least 1+ cells or flare in the anterior chamber, 1+ vitreous cells and/or haze or angiographic evidence of active inflammation as noted by the investigators.
Results:
We identified 73 patients with UC-associated uveitis and 11 had a history of colectomy. Post-colectomy uveitis flares occurred in all 11 patients. Notably, eight patients experienced de novo uveitis activity following their colectomy. The remaining three uveitis patients had documented uveitis flares prior to colectomy. A total of 25 flares were documented, including multiple recurrences in three patients. One patient experienced 13 flares and ultimately required enucleation. Excluding this difficult case, patients with long-term follow-up (≥1 year) generally responded to topical steroid therapy. However, several flares occurred despite concurrent immunomodulatory therapy.
Conclusion:
This case series highlights that uveitis flares may persist or recur following colectomy in UC patients, supporting the hypothesis that uveitis activity can occur independently of intestinal inflammation. These findings support the need for continued ophthalmologic surveillance in UC patients post-colectomy.

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...

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...
Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Appendicitis-II: Diagnostic Studies and Management
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
