Ophthalmological findings in neuroborreliosis - a prospective study performed in western Sweden.

PURPOSE: To evaluate and follow-up ophthalmological findings in individuals diagnosed with neuroborreliosis, confirmed by cerebrospinal fluid (CSF) analysis. METHODS: Twenty-four individuals (13 males), mean age 43.5 ± 18.2 years, with strong clinical suspicion of neuroborreliosis, were referred to the Department of Ophthalmology by the Department of Infectious Diseases at Sahlgrenska University Hospital, Gothenburg, Sweden. All subjects underwent serological and CSF analysis. A structured history taking and a detailed ophthalmological examination were performed prospectively. RESULTS: Diagnosis for neuroborreliosis was confirmed as definite in 16, possible in two and negative in four individuals, while two had unknown diagnosis. The majority (n = 14/18) with definite and possible diagnoses had ophthalmological symptoms and/or findings either in history or at examination. The most common findings were visual disturbance, diplopia, red eyes, photophobia, facial palsy with palpebral diastasis, strabismus and sixth nerve palsy. The number of symptoms and findings was correlated with immunoglobulin G (IgG)/IgM in CSF (r = 0.6, p = 0.009/0.016; Spearman's correlation). All subjects improved, except one with initially fulminant papilloedema, who still suffered from optic disc atrophy and affected visual fields at the last follow-up. CONCLUSION: The majority of patients diagnosed with neuroborreliosis had ophthalmological symptoms and/or findings. Facial palsy with palpebral diastasis was a common finding. Onset of diplopia and/or sixth nerve affection may be a first sign of neuroborreliosis. Number of ophthalmological findings was correlated with the CSF antibody titre. Ticks are becoming more widespread and abundant, resulting in a higher incidence of neuroborreliosis. Hence, the knowledge of ophthalmological symptoms and findings is of great importance.

[Secondary syphilis with ocular involvement in a 77-year-old man]. / Sekundär syfilis med ögonengagemang hos en 77-årig man.

A 77 year old man complained of vision loss and presented psoriasiform skin manifestations. A bilateral panuveitis was observed and after extensive investigation including vitrectomy the patient was diagnosed with secondary syphilis with ocular involvement. Syphilis has shown an increasing incidence in Sweden especially within the group of men who have sex with men. This case report reminds us of the diversity of symptoms which syphilis may present and the importance of PCR to demonstrate Treponema pallidum.

Fuchs' heterochromic uveitis: a longitudinal clinical study.

PURPOSE: To carry out a longitudinal study of patients with Fuchs' heterochromic uveitis (FHU) in western Sweden and to establish the factors responsible for diagnostic delay. METHODS: A sample of 54 patients, 51 with monocular and three with binocular FHU, were followed for periods ranging from 8 months to 15 years. Firm diagnostic criteria were set. A detailed anamnesis regarding ocular and extraocular symptoms was taken. The eyes were repeatedly examined. Toxoplasma serology was analysed. Complications were noted. RESULTS: The delay between the first visit to an ophthalmologist and diagnosis was 0-26 years. The most common first symptom was floaters. Iris heterochromia was absent in 11 patients and discrete in 26. Iris atrophy (a diagnostic criterion) was easy to miss. Chorioretinal scars were found in six patients. Toxoplasma serology was positive in 18 (35%) patients. The only serious complication was glaucoma. CONCLUSIONS: The most important reason for delay in diagnosis of FHU is, in our opinion, failure to consider the disease as a diagnosis. This failure may occur because heterochromia is often missing or discrete, iris atrophy is easily overlooked, and vitreous opacities are common, often cause early symptoms and can explain prolonged workup and therapy. A connection with toxoplasmosis in individual cases cannot be excluded but toxoplasmosis cannot be considered a major aetiological factor. If detailed anamnesis is negative and diagnostic criteria are fulfilled, no further workup is required.
