Measurement of the retinal venous pressure with a new instrument in healthy subjects.

Background: The retinal venous pressure (RVP) is a determining factor for the blood supply of the retina as well as the optic nerve head and until recently has been measured by contact lens dynamometry (CLD). A new method has been developed, potentially offering better acceptance. The applicability and the results of both methods were compared.

[Initial ophthalmic manifestation of a fatal underlying disease : Importance of perimetry in unspecific visual deterioration].

A 55-year-old male patient presented with bilateral blurred vision. Chronic lymphocytic leukemia was generally known in the medical history, which was treated by immunochemotherapy with fludarabine, cyclophosphamide and rituximab. Static perimetry revealed a homonymous hemianopia to the left.

[Scedosporium apiospermum-a rare pathogen of keratomycosis].

This article presents the case of a 44-year-old contact lens wearer who presented with acute keratitis resistant to antibacterial treatment in the right eye. The anterior segment of the eye showed circular conjunctival hyperemia, a corneal white cell infiltrate with radiating margins and a central corneal erosion. Microbiological investigation of a corneal scraping revealed growth of Scedosporium apiospermum.

Central retinal venous pressure is higher than intraocular pressure during amateur trumpet playing.

Background: It has been shown in the literature that the Valsalva manoeuvre influences ocular perfusion by changing intraocular pressure and central retinal venous pressure (CRVP). High-resistance wind instrument (HRWI) playing is a common situation resembling a Valsalva manoeuvre. The aim of this investigation was to explore the influence of amateur trumpet playing on CRVP.

[Unusual coloboma of the optic disc?].

A twelve-year old girl presented herself for a routine ophthalmologic examination in our clinic. Best-corrected visual acuity (BCVA) was 1.0 on both eyes.

[Visual impairment due to rare optic nerve tumor].

A 49-year-old male patient presented with acute symptoms of reduced vision and relative afferent pupillary defects. Static perimetry testing revealed severe visual field defects and the diagnosis of neuritis of the optic nerve was suspected. A magnetic resonance imaging (MRI) scan was performed and showed an intraocular right-sided semicircular mass around the optic nerve which was partially calcified in computer tomography (CT).
