BEHRENS, M.D. Abstract It is not unusual for various ocular diseases to be associated with inflammatory bowel disease. Ocular involvement includes the inflammatory entities of keratitis, conjunctivitis, episcleritis, orbital pseudotumor, iritis and neuroretinitis, as well as those states in which the etiology remains undefined, i.e., scleromalacia perforans, peripheral corneal ulceration and furrow, retinal artery occlusion, and optic neuropathy. We report five cases of optic neuropathy associated with ulcerative colitis to emphasize that this may be the sole ocular manifestation of inflammatory bowel disease. Crohn reports an unusual complication of ulcerative colitis in two women during severe attacks of diarrhea. 1 The report states that each patient was intensely photophobic and had peripheral ulceration of the cornea. I Since 1925, these cases are often cited in the literature and usually are described as demonstrating corneal inflammation and iritis in association with ulcerative colitis. 2,3 In recent years, it is clear that ocular disease occurs with Crohn's disease or granulomatous ileocolitis in variety and frequency similar to that with ulcerative colitis.2-1o Many authors now refer to ulcerative colitis and Crohn's disease under the general rubric, "inflammatory bowel disease," because of the difficulty in separating these two entities strictly into either ulcerative colitis or Crohn's disease in about 20% of casesll and because of similarity of the complications seen with the diseases.5,6, 11, 12 If one disregards eye pathology that seems only coincidentally found in patients with inflammatory bowel disease-like congenital cataracts and interstitial keratitis of luetic origin-the occurrence of ocular disease related to in- From the Departments of Ophthalmology (LAS, TGK.

March 1984 flammatorl bowel disease is around 2-5% of patients.2 - .13,14 Most frequently reported is iritis, which may occur in nearly 50% of patients who have arthritic involvement of the sacroiliac joint,2' 14 but episcleritis, conjunctivitis, and keratitis are also reported with inflammatory bowel disease.2-5, 13 "Ischemic optic neuropathy" is also reported. 15 We report three cases of optic neuritis, one of recurrent papillitis with uveitis, and a case of neuroretinitis with retinal vasculitis in patients with ulcerative colitis. Case Reports Case 1 A 38-year-old woman experienced an acute decrease of vision in her left eye. Visual field testing showed an inferior arcuate paracentral scotoma in her left eye. There was blurring of the superior disc margin, and a diagnosis was made of optic neuritis. Initially, she was treated with 60 mg of oral prednisone/day, which was rapidly tapered over a 10-day period. Examination 14 days later revealed a visual acuity of 20/20 in each eye, but the inferior arcuate scotoma in her left visual field persisted. There was still blurring of the superior disc margin in this eye as well. Laboratory studies including complete blood count, antinuclear antibody test, lupus erythematosus preparation, protein electrophoresis, and serology were all negative or normal, and an erythrocyte sedimentation rate was 5 rnrn/hour. The patient reported an illness diagnosed as ulcerative colitis several months prior to her episode of optic neuritis; this was treated with corticosteroid enemas. Case 2 A 21-year-old woman had the acute onset of pain with movement of both eyes. The retroocular pain on the right side abated, but persisted on the left, and she noted a decrease of vision in her left eye 2 weeks later. Examination at that time revealed a visual acuity of 20/20 in the right eye and finger counting in the left. Kinetic perimetry demonstrated a central scotoma with an inferior 3 Inflammatory Bowel Disease altitudinal defect in her left visual field. There was mild pallor of the inferotemporal quadrant of the left optic disc. Optic canal views and skull x-rays were normal; complete blood count, antinuclear antibody test, and serology were normal. The erythrocyte sedimentation rate was 30 mm/ hour. The patient had known ulcerative colitis since age 9 years. She experienced only occasional flare-up of her bowel problem. She was treated with 80 mg of oral prednisone/day. Although her visual acuity improved to 20/20, she continued to have relative color desaturation in her left eye. A relative afferent pupillary defect was also present. Case 3 A 26-year-old woman had a sudden loss of vision in her left eye associated with pain on movement of the globe. A diagnosis of optic neuritis was made, and she was treated with 60 mg of oral prednisone/day on a gradually tapering dose. High-resolution computerized tomography with orbital views, with and without contrast agent, was normal. Examination 23 days later revealed a visual acuity of 20/20 in her right eye and "hand motions" in her left eye. Kinetic perimetry demonstrated a large central scotoma in her left visual field. Funduscopic examination revealed blurring of the nasal border of the left optic disc. The patient had a 9-year history of ulcerative colitis. Two weeks prior to her visual loss, she experienced a recrudescence of her bowel disease. This activation was treated successfully with sulfasalazine. Case 4 A 36-year-old women noted that the vision in her right eye was hazy. She had disc edema on the right and was advised to discontinue the use of her oral contraceptives. Examination several weeks later showed vision of 20/30 and 20/15 in her right and left eyes, respectively. There was an afferent pupillary defect and color desaturation on the right. Kinetic perimetry revealed an enlarged blind spot extending nearly to fixation. She had a mild anterior uveitis with 2+ cell and 1-2+ flare with fine keratic precipitates in her right eye. The right optic disc was edematous with several nerve fiber layer hemorrhages and cotton-wool spots. Skull x-rays, optic canal views, and chest x-ray were normal; complete blood count, antinuclear antibody test, lUpus erythematosus preparation, total complement levels, rheumatoid factor, serum protein electrophoresis, and serology were normal or negative, as were a neurologic examination and lumbar puncture. She was treated with 50 mg of oral prednisone/ day and a topical corticosteroid preparation for the right eye. The vision in her right eye improved to 20/20. The right disc was mildly atrophi~, and asymptomatic disc swelling was ~bserved m her left eye which resolved over a penod of 1 month. She was asymptomatic for 3 years when. she noted blurring of vision in her left eye assoClated with a fever and diarrhea. Examination 3 weeks later revealed a visual acuity of "finger counting" in her left eye. She had an anterior uveitis with 2+ cell and flare in the anterior chamber and an occasional cell in the anterior vitreous body. Mild pallor of the right disc was seen as well as moderate swelling of the left disc. Her erythrocyte sedimentation rate was 102 mm/hour. A barium enema revealed ulceration and atony of the colon compatible with a diagnosis of ulcerative colitis. Sulfasalazine was begun with subsequent resolution of her diarrhea and normalization of her erythrocyte sedimentation rate to 4 mm/hour within 2 months. Oral prednisone was added without effect, as her vision remained at a "finger- counting" level. Case 5 A 40-year-old man presented with the complaint of decreased vision in his right eye. He had a known childhood amblyopia in his left eye. During a routine examination 2 years previously, he was found to have retinal telangiectasia with intraretinal hemorrhage and subretinal exudate, compatible with a diagnosis of Coat's disease. He was treated elsewhere with laser photocoagulation. Examination revealed a visual acuity of 20/ 25 in his right eye and "finger counting at several feet" in his left eye. Fundus examination showed bilateral disc edema. There were sheathing of arterioles, scattered intraretinal hemorrhages and cystOid macular edema in his right eye. Kinetic perimetry demonstrated a normal visual field on the right side and a large central scotoma on the left. The patient was known to have Crohn's disease, diagnosed by colonic biopsy 18 months previously. He was taking sulfasalazine for his bowel disease and was asymptomatic. Radiographic evaluation, with the exception of colonic diverticuli, was normal; however, on colonoscopy patchy areas of erythema were noted. Biopsy showed chronic mild inflammatory changes. The patient's antinuclear antibody test, histocompatibility antigen-B27, and other collagen vascular laboratory studies were negative or normal, as were cerebrospinal fluid studies. He was treated with pulsed methylprednisolone followed by oral prednisone with improvement of his retinal vasculitis, and the vision in his right eye improved to 20/20. Side effects of the steroid therapy necessitated steroid withdrawal with a decrease in the vision in his right eye. Azathiaprine, chlorambucil, and indomethacin all were ineffective. Colchicine was tried, but not tolerated because of severe diarrhea. Journal of Clinical Neuro-ophthalmology Comment According to Kirsner and Shorter,II.12 inflammatory bowel disease has an annual incidence of 4-6/100,000 and an incidence of 40-100/ 100,000.12 It occurs predominantly in industrialized countries. People who move from rural to urban areas incur a higher risk for the development of inflammatory bowel disease. 12 This disease can occur in families and affects whites more often than .blac~s.12 Various environmental pathogens are ImplIcated, but no clear association is found. 12 A number of autoimmune perturbations are found in patients with inflammatory bowel disease, but may be a consequence of the disease process itself. 12 The development of extraintestinaI manifestations of inflammatory bowel disease is not yet linked definitively to the basic pathophysiologic process. 12 The literature concerning the complications and extraint~stinal . manifestations of inflammatory bowel dIsease IS extensive. Iritis and corneal dis~ ase are documented to occur in patients with m~ammat.orybowel disease.2-5.12 In several large sene.s of mfl~mm.atory bowel disease patients, passmg mentIon IS occasionally made of rarer a.ssociat~~ ~cula~ diseases ~~ch as retrobulbar optic neuntis, orbItal myoSItis,4 and retinal artery occlusion.4Over the last several years, many welldocumented cases of unusual ocular inflammat~ ry disease occurring with inflammatory bowel disease are described: 1) bilateral orbital myositis in a 14-y~ar-old boy who subsequently developed b~oody diarrhea and whose diagnosis of Crohn's disease was made from small bowel biopsyl6; 2) sc~eromalacia perforans in a 36-year-old man WIth an II-year history of ulcerative colitis and negative rheumatoid factor latex and antinuclear antibody, who resolved his eye lesion after total ~roctocolectomi7; 3) a characteristic elevated penpheral corneal opacity with subepithelial infiltrates seen in three patients with known Crohn's diseas~, ~hich ~n tum led to the diagnosis of C~ohn s disease In another patient who presented ~Ith eye symptoms and keratopathy only8; 4) bIlateral retinal branch arterial occlusion in a 34ye~ r-old man with Crohn's disease reported in a s~nes of other patients with inflammatory bowel disease a~d cerebr~l t~rombosis6; 5) a 17-yearold bf1y WIth Crohn s disease status post resection of the terminal ileum and ascending colon, who ?eve~oped retinitis, papillitis and vitritis in conJunction with a reactivation of his bowel disease7. and 6) a 24-year-old man with Crohn's diseas~ who developed uveitis in his right eye and bilateral optic neuropathy. 15 We d~scribe five cases of optic neuropathy to emphasIze the possibility of serious visual loss ~rom optic nerve involvement in patients with I~flammatory bowel disease. As in the two prevIOusly .well-d?c~mented cases,8.15 we see optic nerve disease m mflammatory bowel disease as March 1984 Sedwick, Klingele, Burde, Behrens part of the picture of generalized ocular inflammation (cases 4 and 5) and in isolation; i.e., three of our patients (cases 1, 2, and 3) have optic neuropathy without any associated findings of uveitis, retinitis, vitritis, or other ocular inflammatory disease. This is the first report of optic n~uropathy in patients with inflammatory bowel dIsease occurring in the absence of other ocular inflammatory signs. Although the pathogenetic mechanism of inflammatory bowel disease is unknown, the ogtic neuritis resembles autoimmune optic neuritis 8 and supports the concept that the ocular inflammatory effects are mediated immunologically. This is consistent with the hypothesisl2 that the intestinal lesions of inflammatory bowel disease are initiated by an external agent, possibly microbial, viral or dietary, and the ocular lesions represent epiphenomena which are mediated immunologically. . As in othe~ optic neuritides, therapeutic options In these patients are on less than solid ground. However, because corticosteroid therapy appears to ameliorate certain other manifestations of inflammatory bowel disease, and we have had similar success in treating autoimmune optic neuri-tI. s, 18·It seems reasonable to treat these presumed cases of inflammatory optic neuropathy with corticosteroids. Four of the five cases (1, 2, 4, and 5) show substantial improvement with this therapy. Some authors note a correlation between the occurrence of eye disease and "activity" of the bowel dise~se:J· 14.17 However, this relationship does not eXIst m our cases, with the exception of case 4. Resolution of ocular disease with colectomy or other surgery is reported, 13.19 and some advocate that the presence of severe iritis or other ocular disease is an indication for bowel resection in the management of severe intestinal disease. J·7 However, others note active eye disease in the face ?f apparent curative surgery for bowel disease.- · J Only. a careful follow-up study specifically addressmg the relationship between bowel resection for inflammatory bowel disease and extraintestinal manifestations will answer this question. Thus, all that is clear at this time is that certain ocul.ar disea~e.s, including optic neuritis, may occur In the mIlIeu of mflammatory bowel disease. The optic neuritis appears to be corticosteroidresponsive if treatment is initiated early. References 1. Crohn, B.B.: Ocular lesions complicating ulcerative colitis. Am. J.
