High-grade malignant B-cell lymphoma of the retina in a patient with concomitant gastric MALT lymphoma.

PURPOSE: To report the unexpected finding of a primary retinal B-cell lymphoma in a patient with previous breast carcinoma and subsequent lymphoma of the stomach. METHODS: Histopathologic and immunohistochemical findings in the enucleated eye are described in conjunction with clinical features and investigations. RESULTS: An 80-year-old woman with previous breast cancer presented with moderate loss of vision associated with vitreous opacities, circumpapillary retinal haemorrhages, and attenuated retinal vessels in her left eye. Treatment with systemic steroids and oral immunosuppressive drugs was initiated on suspicion of carcinoma-associated retinopathy. Two years later, the patient was diagnosed with MALT lymphoma of the stomach. Unfortunately, the ocular symptoms did not improve, and the patient developed neovascular glaucoma, for which the eye was eventually enucleated. Histopathology and immunohistochemistry as well as a molecular analysis revealed a primary B-cell lymphoma of the retina. CONCLUSION: Non-Hodgkin B-cell lymphoma of the retina should be considered as a differential diagnosis in cases of non-specific retinopathies even in the presence of other primary neoplastic co-morbidities.

Visual field changes in methotrexate therapy. Case report and review of the literature.

PURPOSE: To present a unilateral central visual field defect in a patient with psoriatic arthritis treated with Methotrexate and folic acid supplement, probably induced by toxic posterior optic neuropathy. The scotoma incompletely resolved after cessation of Methotrexate (MTX) therapy. METHODS: Serial fundoscopic, perimetric and electrophysiological examination as well as comprehensive neurological investigation including lumbar puncture, carotid sonography, electroneurography, and MRI of the brain. RESULTS: A female patient with psoriatic arthritis on long-standing Methotrexate (MTX 15 mg IM/once a week) therapy suffered first from an acute attack of central visual field defect in her right eye and later on from two subsequent deteriorations of her scotoma within one year. A demyelinating retrobulbar optic neuritis was excluded through repeated comprehensive neurological investigations and unresponsiveness to systemic corticosteroid therapy. A MTX-induced posterior optic neuropathy was suspected and the patient experienced improvement of her visual field defects only six weeks after discontinuing MTX therapy. Further improvement was observed through follow-up perimetric examinations half a year after cessation. CONCLUSIONS: Central scotoma with unremarkable optic disc can occur after long-standing treatment with MTX and despite folic acid supplementary therapy. This is most probably due to posterior optic neuropathy. Early cessation of the drug or change to another antimetabolite therapy can stop the deterioration of the visual field changes and even improve them. The exact pathomechanism is still unclear and the involvement of only one eye requires more investigation. MTX-induced posterior optic neuropathy should be included in the differential diagnosis of toxic optic neuropathy. This is getting more frequent than before because of the nowadays standard use of MTX in treatment of many autoimmune collagen diseases.

Loa loa macrofilariasis in the eyelid: case report of the first periocular subcutaneous manifestation in Germany.

PURPOSE: We report a case of periocular subcutaneous macrofilariasis as an initial sign of a systemic Loa loa infection. METHODS: Thorough history, eye examination and surgical intervention. Parasitological and serological analysis. RESULTS: A periocular adult Loa loa worm was extracted from the left upper eyelid in an African student living in Germany after presenting to our department with intermittent attacks of painful lid swelling. Four weeks later he presented with Calabar swellings in his arms without serological evidence of microfilaria and was treated with diethylcarbamazine. CONCLUSION: Due to increasing migration of populations to Europe rare manifestations of ocular loiasis are becoming more common. Intermittent painful eyelid swelling in patients who visited or have lived in Africa should always raise the suspicion of systemic loiasis.

Jesus and the eye: New Testament miracles of vision.

PURPOSE: To compile and appraise the accounts of the miracles of vision in the New Testament. METHODS: We carried out a critical analysis of the compilation of ocular miracles using past medical knowledge and historical reconstruction based on the accounts of the apostles and of various historians living in the first three centuries ad. RESULTS: Three blind adult male beggars residing on three different street locations were described. Two had previously had good vision that had declined over a long time and the third had been born blind. The manifestations of the ocular diseases in these cases were meagre, precluding any precise diagnosis. The healing methodology did not rely on physical examination, detailed history, or the use of medicines. Jesus' tools consisted of spitting, touching, praying and the use of words. Visual outcome reported as a complete cure was realized in all three incidents. CONCLUSIONS: The accounts of miracles in the Gospels appear to be historically reliable, yet subject to different interpretations: faith in the miracle (the Christian perspective); sorcery (the Jewish perspective); mythology (the atheist perspective), and scientifically possible human action by a charismatic, compassionate, knowledgeable man (the scientific perspective: psychotherapy or suggestion).

Recurrent retinal vein occlusion after playing a wind instrument.

PURPOSE: To present a complication of repeated Valsalva maneuver. METHODS: Case report with serial intravenous fluorescein angiography and comprehensive workup for coagulopathies. RESULTS: After playing strenuous musical pieces, a solo trombonist suffered within 1 year three attacks of visual loss in the right eye; he had two attacks of inferior hemi-central retinal vein occlusion 2 months apart, followed by central retinal vein occlusion 10 months later. Final best spectacle-corrected visual acuity was 6/60. He ended his professional career, and no further attacks occurred in the following 10 years. CONCLUSION: Retinal vein occlusion with irreversible visual loss can occur after playing a strenuous piece of music on a high-resistance instrument.
