Vasculitic central retinal vein occlusion: The presenting sign of seronegative rheumatoid arthritis

Vasculitis associated with the use of an intrauterine device: A case report

Retinal vasculitis is a complication associated with a local condition or it can be a retinal expression of a systemic inflammatory disorder, which initially may go unnoticed. Drug-associated vasculitis is frequently difficult to identify, because many patients follow treatments with more than one drug and the route of administration varies. A 35-year-old female patient presented with sudden hearing loss, headache and blurred vision that had started two weeks earlier and had become progressively worse. Ophthalmological examination revealed anterior uveitis, bilateral optic disc swelling and retinal vasculitis. The orbito-cerebral MRI, the CT scan and the serological tests were within normal limits. Unable to identify the cause of the retinal vasculitis, the patient's medical history was reviewed. The patient had recently had a gynecological procedure, where a 13.5 mg levonorgestrel intrauterine contraceptive device was implanted. After the device was removed and methylprednisolone treatment started, the patient presented a visible remission of the symptoms and signs. To the best of our knowledge, there is no case of retinal disease and optic disc edema associated with auditory problems caused by an intrauterine device. A proper examination, correlated with a very thorough medical history, could identify rare diseases and associations, in order to provide adequate medical care.

The main aspects of retinal vein occlusion etiopathogenisis in young adults. Part I. Neuroretinovasculitis (prothrombotic potential, clinical manifestations)

This review is dedicated to the neuroretinovasculitis, which is the leading cause of retinal vein occlusion in young adults. Presumed etiological factors, possible pathogenic mechanisms, and clinical manifestation are analyzed. Advisability of multidisciplinary approach in management and individual approach in treatment of patients with neuroretinovasculitis with secondary retinal vein occlusion are justified.
