Full-Thickness Macular Hole: An Exceptional Case Presentation in Behçet's Disease

Behçet's disease (BD) is a vascular disorder affecting a variety of organ systems. It is an auto-immune disease with inflammatory vasculitis that is systemic in nature, the exact etiology of which is unknown. Obliterative vasculitis, recurrent aphthous ulcers, mucocutaneous manifestations, recurrent genital ulcerations, and intraocular inflammation, especially chronic relapsing uveitis, are the characteristic features of BD. The case report presents a unique manifestation of BD in a 20-year-old Pakistani male who presents with a one-year-old history of viral encephalitis, after which he developed a blurring of vision. On examination, he had recurrent aphthous ulcers, recurrent ulcerations of genitalia, and a history of lesions of the skin. After making the patient undergo a cascade of investigations for evaluating and assessing the various signs and symptoms, a diagnosis of BD with bilateral panuveitis and a full-thickness macular hole (FTMH) in the right eye was established. Immuno-suppressants, steroids, and azathioprine were used as treatment options, following which the state of remission was attained.

[Ocular manifestations of Behçet's disease]

INTRODUCTION

Behçet's disease is a systemic inflammatory disease. Ocular involvement is an important diagnostic criterion, and this disease may be associated with severe visual loss.

PURPOSE

The goal of this study was to specify the epidemiological, clinical and therapeutic features of ocular involvement in patients with Behçet's disease and to identify risk factors for poor visual outcomes.

METHODS

A retrospective study was performed in 93 patients diagnosed with ocular Behçet's disease over a period of 9 years. Epidemiological, clinical, and therapeutic data was obtained from medical records and analyzed retrospectively. Poor visual outcome was defined as visual acuity limited to light perception without projection or no light perception.

RESULTS

The male:female ratio was 1.9. The mean age was 34.5 years. Ocular involvement was the presenting sign in 4%, bilateral in 61% and active in 68.8%. Uveitis was the most common presentation (57%), dominated by panuveitis, followed by retinal vasculitis (51.6%) and papilledema (10.7%). Maculopathy (26.8%) and cataract (18.2%) were the most common complications. Twenty patients (21.5%) had no light perception or light perception without projection. Treatment was based on corticosteroids in combination with immunosuppressive therapy (Azathioprine) in 55.9% of cases. Our study indicates a significant association of male gender and panuveitis with a poor visual outcome.

CONCLUSION

Ocular involvement in Behçet's disease is frequent and serious, which may lead to blindness. Male gender and panuveitis were predictors of poor visual prognosis.

[Epidemiological, clinical, therapeutic and evolutionary profile of ocular manifestations in patients with Behçet's disease]

Le but de ce travail est d'étudier le profil épidémiologique, clinique, thérapeutique et évolutif des manifestations oculaires au cours de la Maladie de Behçet. C'est une étude rétrospective descriptive étalée sur une période d'un an et demi entre janvier 2015 et juin 2016 analysant les dossiers de 121 patients suivis à la consultation spécialisée de la maladie de Behçet. La moyenne d'âge était de 35 ans, 63,6% des patients étaient de sexe masculin, l'atteinte oculaire était inaugurale dans 24% des cas. Les patients présentaient une uvéite antérieure (7,4%), une uvéite postérieure (15,7%), une vascularite (19%), des synéchies irido-cristalliniennes (17,5%), un œdème maculaire (7,4%), une atrophie optique (4,1%), un œdème papillaire (2,5%) et une ischémie rétinienne périphérique (1,7%). Dans notre série 41,3% des patients étaient sous colchicine, 23,1% sous corticoïdes par voie orale, 9% sous corticoïdes par voie intraveineuse, 4,9% sous corticoïdes topiques, 8,2% sous immunosuppresseurs et 5,8% sous anti-vitamine K. Sur un recul moyen d'une année, 40% des patients avaient une acuité visuelle stable sous traitement, 23% ont présenté une baisse significative de l'acuité visuelle dont 5% des cas de cécité absolue. Une prise en charge thérapeutique correcte permet de juguler rapidement la poussée inflammatoire et de réduire la fréquence et la gravité des récidives ce qui se traduit par une amélioration du pronostic visuel de nos patients par rapport à des séries antérieures.

Vitreomacular Interface Disorders in Behçet's Uveitis

Objectives:

To determine the prevalence of vitreomacular interface (VMI) disorders in patients with Behçet’s uveitis and assess the relationship between VMI disorders and clinical characteristics.

Materials and Methods:

The macular optical coherence tomography (OCT) images of 160 eyes of 96 patients with Behçet’s uveitis who were being followed in the Uvea-Behçet’s clinic were assessed retrospectively for VMI disorders including posterior vitreous detachment (PVD), epiretinal membrane (ERM), vitreomacular adhesion (VMA), vitreomacular traction (VMT), full-thickness macular hole (FTMH), lamellar hole (LH) and pseudohole.

Results:

Twenty-four patients (25%) with unilateral and 72 patients with bilateral uveitis were included in the study. Six (30%) of 20 eyes with anterior uveitis and 57 (40.7%) of 140 eyes with posterior uveitis, in total 63 (39.4%) eyes of 160 eyes had at least one VMI disorder. PVD was detected in 4 eyes (2.5%), ERM in 48 eyes (30%), VMA in 12 eyes (7.5%), and LH in 1 eye (0.6%). None of the eyes had VMT, FTMH, or pseudohole. ERM was detected in 13 eyes (8.1%) on fundus examination and 48 (30%) eyes by OCT (p=0.001). VMI was detected in 12 (50%) of 24 eyes with prior intraocular surgery and 51 (37.5%) of 136 eyes without. The mean duration of uveitis was 7.3±5.8 years in patients with VMI disorders and 5.8±7.7 years in patients without (p=0.04). There was no relation between VMI disorders and anatomic location of uveitis, history of past ocular surgery, number of ocular/periocular steroid injections, or visual acuity.

Conclusion:

VMI disorders are common in patients with Behçet’s uveitis. Their frequency increases with the duration of uveitis. OCT is more sensitive than fundus examination in the detection of VMI disorders.

Ocular Manifestations, Conventional Fundus Fluorescein Angiographic Findings, and Relationship Between Angiographic Findings and Visual Acuity in Behçet's Disease

PURPOSE

Evaluating the ocular manifestation and fundus fluorescein angiography (FA) findings of patients with Behçet's disease as well as the relationship between visual acuity and angiographic findings.

METHODS

Retrospective chart review of patients with Behçet's disease seen at the Farabi Eye Hospital.

RESULTS

Forty-six patients (92 eyes) with mean age of 33.41 ± 10.67 were included. The most frequent presenting symptom and sign were reduced vision (76%) and uveitis (87%), respectively. Panuveitis was the most frequent type of uveitis (76%). Among patients with FA, vasculitis was the most common finding (87%) and it was significantly more severe among patients with visual acuity less than 20/200. Macular leakage (P = 0.001), arterial narrowing (P = 0.000), and posterior retinal vasculitis (P = 0.002) on FA were all associated with worsening final visual acuity.

CONCLUSION

The most common ocular findings in Behçet's disease were panuveitis and vasculitis. Location of vasculitis, arterial narrowing, and macular leakage on initial FA may predict visual prognosis.

Ocular manifestations of Behçet's disease in Jordanian patients

PURPOSE

To study the prevalence, manifestations and severity of ocular involvement of Behçet's disease in Jordanian patients.

METHODS

The study population consisted of 43 patients diagnosed to have Behçet's disease through Rheumatologist's examinations conducted at Jordan University Hospital between January 2002 and July 2009. The sample involved patients who displayed ocular manifestations. This included 18 patients; 12 males and 6 females with a mean age of 35 years (SD = 17.26). Ophthalmological examinations and retrospective analysis of medical files were carried on.

RESULTS

Ocular manifestations were seen in 41.9% of patients. The most common manifestation for Behçet's disease was vitritis with a prevalence of 55.6%, followed by anterior uveitis and retinal vasculitis (50% for each). On the other hand, the most frequent complications involved were cataract, cystoid macular edema (CMO), posterior synechiae and glaucoma with a prevalence of (44.4%), (33.3%), (11.1%) and (5.6%), respectively.

CONCLUSION

The prevalence and severity of ocular lesions in Behçet's disease is relatively low in Jordanian patients. This result indicates that early diagnoses and intervention might delay or even prevent vision loss for those patients.

Spontaneous closure of macular holes secondary to posterior uveitis: case series and a literature review

The occurrence of a macular hole due to posterior uveitis is infrequently reported. We report the evolution of three cases of macular holes secondary to posterior segment inflammation. A complete inflammatory and infectious assessment found one case of toxocariasis, one of sarcoidosis, and one of syphilis. After medical etiological treatment, macular hole closure was rapidly obtained in all the cases and confirmed by spectral domain optic coherence tomography, with visual acuity improvement. Fibrous scarring developed in two cases, and foveal photoreceptor complex normalization was observed in the sarcoidosis case. These observations demonstrate that macular holes secondary to posterior uveitis frequently resolve without surgical intervention and so could be underdiagnosed if the patient is not evaluated at the time of onset before spontaneous hole closure.

Macular involvement in patients with Behçet's uveitis

PURPOSE

The purpose of this study is to assess macular involvement in patients with Behçet's uveitis.

METHODS

The study included 65 patients (120 eyes) with Behçet's uveitis. All patients underwent detailed ophthalmic examination, including dilated biomicroscopic fundus examination, fundus photography, fluorescein angiography, and optical coherence tomography. Follow-up ranged from 6 to 46 months (mean 20 months).

RESULTS

At initial examination, 29 eyes (24.1 %) had macular involvement including macular edema (16 eyes, 13.3 %), serous retinal detachment (SRD; five eyes, 4.1 %), active retinitis (three eyes, 2.5 %), macular hole (three eyes, 2.5 %), macular atrophy (two eyes, 1.6 %), macular ischemia (one eye, 0.8 %), epiretinal membrane (one eye, 0.8 %), branch retinal vein occlusion involving the macula (three eyes, 2.5 %), and branch retinal artery occlusion involving the macula (two eyes, 1.6 %). During follow-up, 22 eyes (18.3 %) developed macular complications including macular edema (ten eyes, 8.3 %), SRD (four eyes, 3.3 %), active retinitis (two eyes, 1.6 %), severe macular atrophy (two eyes, 1.6 %), macular ischemia (three eyes, 2.5 %), macular hole (one eye, 0.8 %), epiretinal membrane (two eyes, 1.6 %), and subretinal fibrosis (one eye, 0.8 %). Branch retinal vein occlusion involving the macula developed in two eyes (1.6 %). Final best corrected visual acuity in patients with macular involvement ranged from 20/400 to 20/25 (mean 20/80).

CONCLUSIONS

Macular edema and other vision-threatening macular complications are common in Behçet's uveitis. Macular damage is often irreversible, causing permanent visual impairment. Early and appropriate treatment of Behçet's uveitis is mandatory to reduce the risk of visual impairment due to macular involvement.

Macular hole in Behçet's disease

Objective:

To investigate the clinical features, prevalence, role of surgical intervention and the visual prognosis of macular holes (MH) in patients with Behcet's disease (BD).

Materials and Methods:

Retrospective study of patients with BD and MH from January 1998 to November 2008.

Results:

Out of 159 patients, 21 eyes of 17 patients were identified with MH. The mean age was 38.59 (range 23-61) years and the mean follow-up period was 5.1 years (range 13-164 months). The prevalence of MH was 7%. Visual acuity (VA) at the time of presentation ranged from 20/70 to hand-motion. Optical coherence tomography (OCT) findings revealed intraretinal cysts at the edge of the MH. The mean size of MH was 983.6 um; 52% had elevated edges, 43% had flat edges and only one eye (5%) was closed postoperatively. Fluorescein angiography (FA) was consistent with macular ischemia in 76% of the cases. Human leukocyte antigen (HLA) B51 association was found in 14 of the 15 patients investigated. Six patients (out of 17) underwent pars plana vitrectomy. The final VA on their last follow-up ranged from 20/70 to 2/200. Surgical intervention for MH did not result in any visual improvement as compared to non-operated eyes. One patient lost vision completely due to elevated intraocular pressure post vitrectomy and silicon oil tamponade.

Conclusions:

MH in patients with BD may lead to significant visual disability. Surgical intervention does not seem to have any potential beneficial effect on the VA, probably due to significant macular ischemia and sequelae from the ocular inflammation.
