RESUMO
An 18-year-old female patient was referred with complaints of tearing and redness in the left eye for 3 months after a mild ocular trauma with a turkey feather. She was treated with topical antibiotics and corticosteroids with no improvement. Slit-lamp examination of the left eye showed a vascularized lesion with a polypoidal appearance due to multiple contiguous micronodules on the temporal and inferior bulbar conjunctiva. Results of the anterior and posterior segment examination were unremarkable in both eyes. A biopsy specimen of the conjunctival mass showed multiple tuberculoid granulomas composed of epithelioid histiocytes with associated Langhan's type multinucleate giant cells and a necrotic nodule surrounded by histiocytes and giant cells. The Mantoux test was positive with induration of 15mm. The patient was prescribed antituberculosis therapy. Three months after treatment initiation, the conjunctival lesions had resolved. Mycobacterium tuberculosis should be considered in cases of unilateral chronic recalcitrant conjunctivitis. Biopsy of a conjunctival mass is of utmost importance to establish a definite diagnosis.

PURPOSE: To describe clinical features, relevant imaging findings, disease course, and response to treatment in 9 patients (18 eyes) with idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome. METHODS: Retrospective review of the charts of nine patients (18 eyes) diagnosed with IRVAN syndrome at Fattouma Bourguiba University Hospital, Monastir, Tunisia, from January 1, 2011 to January 1, 2022. RESULTS: Nine patients were included with bilateral involvement in all cases. Mean initial best-corrected visual acuity (VA) was 20/32 (range, 20/1600-20/20). Clinical findings at presentation included vitreous cells (10 eyes, 55.6%), peripapillary exudates (12 eyes, 66.7%), partial or complete macular star (11 eyes, 61.1%), and vascular sheathing (11 eyes, 61.1%). Fluorescein angiography showed arteriolar aneurysms (18 eyes, 100%), areas of peripheral capillary non-perfusion (16 eyes, 88.9%), and retinal neovascularization (6 eyes, 33.3%). Optical coherence tomography showed macular edema in 5 eyes (27.8%). Optical coherence tomography angiography of the optic disc demonstrated papillary aneurysms in 4 eyes of 2 patients. Indocyanine green angiography showed retinal arteriolar aneurysmal dilatations in 4 eyes of 2 patients. Ten eyes (55.6%) had stage 2 disease, 6 eyes (33.3%) had stage 3, and 2 eyes (11.1%) had stage 1. Treatment modalities included peripheral photocoagulation (16 eyes, 88.9%), intravitreal bevacizumab (4 eyes, 22.2%), and intravitreal triamcinolone acetonide (1 eye, 5.6%). Mean final best-corrected VA was 20/32 (range, 20/600-20/20). Ocular complications included vitreous hemorrhage in 3 eyes (16.7%), branch retinal artery occlusion in 2 eyes (11.1%) and submacular fibrosis in 3 eyes (16.7%). CONCLUSION: IRVAN syndrome should be highly suspected in patients with peripapillary exudates associated with vascular sheathing and vitreous cells. Multimodal imaging confirms the diagnosis by showing retinal macroaneurysms. Early treatment of macular edema and/or peripheral retinal non-perfusion is mandatory to improve prognosis.

PURPOSE: To study the effect of ocular inflammation in active uveitis on the corneal endothelium. MATERIALS AND METHODS: This is a prospective cross-sectional study involving 63 eyes of 38 patients with active newly-diagnosed uveitis. Eighty-four eyes of 42 non-uveitic subjects served as a control group. All patients underwent detailed ophthalmic examination, laser flare photometry, and non-contact specular microscopy. Eyes with uveitis had a follow-up visit at one month after initiation of treatment, including laser flare photometry and specular microscopy. RESULTS: The mean age of the active uveitis patients was 33 (range: 9-67 years) with 21 men (55%) and 17 women (45%). For the uveitis patients at baseline, the mean flare value was 32ph/ms (range: 15-100ph/ms) with flare photometry value ≥50ph/ms in 13 eyes (21%) and<50ph/ms in 50 eyes (79%). At baseline, cell density (CD) of the uveitis patients was similar to CD in control eyes (pê0.16). The percent of hexagonality was significantly lower (p<0.0001), and the coefficient of variance (CV) (p<0.0001) and central corneal thickness (CCT) (p<0.0001) were significantly higher than in the control group. After one month, there was a significant decrease in flare photometry values (p<0.0001), with a mean flare value of 14.5ph/ms (range: 4-60ph/ms). In the active uveitis group, the overall results of specular microscopy did not significantly vary between the initial examination and the 1-month examination. For eyes with flare photometry value ≥50ph/ms at baseline, CD and hexagonal cell count significantly increased on the 1-month examination (pê0.01 and pê0.02 respectively), while CV and CCT decreased significantly at the one-month follow-up visit (pê0.007/pê0.03 respectively). For eyes with flare photometry value at baseline <50ph/ms, there was no significant differences in specular microscopy results between the initial examination and the 1-month examination. CONCLUSIONS: In eyes with newly-diagnosed uveitis and active anterior chamber inflammation, specular microscopy shows transient qualitative abnormalities of the corneal endothelium that depend on the severity of the anterior chamber inflammation as measured by the laser flare meter.

Behçet's disease is a chronic multisystem disorder characterized by relapsing inflammation for which the underlying histopathology is an occlusive vasculitis. The disease has a high prevalence in the Mediterranean region, Far and Middle Eastern countries. It is clinically characterized by oral and genital ulcerations, ocular inflammatory involvement, skin lesions, vascular involvement and numerous other systemic manifestations. Uveitis is by far the most common ocular manifestation of Behçet's disease. It typically presents in the form of relapsing-remitting panuveitis with retinal vasculitis that may result in severe visual loss. Management of Behçet's uveitis relies on corticosteroid therapy, conventional immunosuppressive drugs and biological agents and requires a close collaboration between ophthalmologist and internist. A better understanding of the auto-inflammatory process and of the role of cytokines implicated in the pathogenesis of Behçet's disease will enable researchers to develop more specific and effective therapy.

BACKGROUND: Idiopathic orbital inflammatory syndrome (IOIS) is an inflammatory condition of unknown etiology. The inflammation may affect all the structures within the orbit (anterior, diffuse, apical, myositic, dacryoadenitis) and corresponds to uniquely orbital inflammation without an identifiable local cause or systemic disease. The goal of this study is to describe the clinical and radiographic characteristics of IOIS and discuss the role of orbital biopsy in this condition. PATIENTS AND METHODS: This is a retrospective review of the charts of 24 patients diagnosed with IOIS at Fattouma Bourguiba hospital, Monastir, Tunisia, from January 2007 to December 2015. This study included all patients with IOIS and a minimum follow-up of six months. All patients had a complete ophthalmological examination and orbital and head CT scan and/or MRI. A work-up was performed in all cases to rule out local causes and systemic disease. Only 11 patients underwent biopsy. The diagnosis of the clinical entity IOIS was made according to the Rootman criteria. Oral steroids were the first line therapy. A bolus of intravenous methylprednisolone was administered first in vision-threatening cases. Response to treatment was defined as disappearance of signs and symptoms of IOIS. RESULTS: Orbital pain was the most common symptom (62.5%), followed by proptosis and decreased vision (37.5% each). Best-corrected visual acuity (BCVA) was greater than 5/10 in 70.7% of patients. Lacrimal gland enlargement was observed in 3 patients. Oculomotor disorders were present in 70% of cases and 20.8% of patients had compressive optic neuropathy. Orbital imaging showed, in most cases, oculomotor muscle inflammation (87.5%) involving particularly the superior rectus muscle (54.2%) and inflammation of orbital fat (66.7%). Fifty percent had myositic inflammation. Biopsy was performed in 11 patients, showing nonspecific inflammation (n=10) and the sclerosing form (n=1). A total of 83.3% of patients received oral corticosteroids for a mean duration of 5.5 months. CONCLUSION: IOIS is a diagnosis of exclusion, based on history, clinical course, response to steroid therapy, laboratory tests, or even biopsy in selected cases. Orbital imaging provides valuable clues for diagnosis of IOIS and for identification of affected structures. Prolonged steroid therapy is necessary as IOIS classically responds to steroids; nevertheless, partial recovery or relapses often occur.

INTRODUCTION: Pachydermoperiostosis or primary hypertrophic osteoarthropathy is a rare cause of ptosis. We report the case of a patient with pachydermoperiostosis and bilateral ptosis. The physiopathology and treatment of this ptosis are discussed. CASE REPORT: A 49-year-old patient was referred to our department with ptosis. He had pachydermia of the face, hands and the feet, digital clubbing and periostosis. Examination of the eyelids showed that palpebral apertures were reduced to less than 4mm bilaterally and that eyelids were markedly thickened. All theses features were consistent with the diagnosis of pachydermoperiostosis. Other secondary conditions were ruled out. Ptosis correction was performed by palpebral skin and orbicularis resection as well as tarsectomy. The aesthetic outcome was satisfactory. DISCUSSION: Pachydermoperiostosis is a rare inherited disease, characterized by pachydermia, digital clubbing and periotosis. Ptosis is the result of the palpebral hypertrophia. Excisions of skin, orbicularis muscle and tarsus often give good cosmetic outcomes. CONCLUSION: Pachydermoperiostosis is a rare cause of ptosis, which development is attributed to eyelid thickening. Surgical management has satisfactory cosmetic outcome.

Ochronosis or alkaptonuria is a rare inherited disease. It is characterized by the deposition of dark pigments in collagen-rich tissues, which leads to clinical manifestations such as arthropathy. The ochronotic pigment can be found in the sclera, the conjunctiva, and the limbic cornea. Vision is usually not affected. We report the case of 47-year-old patient who complained of lower back pain. Ophthalmologic examination showed dark pigments in the conjunctiva. The increased levels of homogentisic acid in urine confirmed the diagnosis of ochronosis.
