Aims: To identify the contributory factors associated with different sites of occlusion and the presence or absence of optic nerve head swelling (ONHS).

Methods: 874 cases of retinal venous occlusion (RVO) were prospectively examined at a tertiary referral centre and classified according to three defined sites of occlusion: arteriovenous crossing RVO (AV-RVO); optic cup RVO (OC-RVO); and optic nerve sited RVO. Optic nerve sited RVOs were further divided on the basis of presence (ONHS-RVO) and absence (NONHS-RVO) of ONHS.

Varix of the vortex vein ampulla is a rare, benign, asymptomatic condition, which may be confused with a choroidal naevus or melanoma. A 28-year-old man was referred to a tertiary retinal practice with a diagnosis of choroidal naevus. The lesion was an elevated choroidal mass in the superonasal peripheral retina measuring 2 by 1 disc diameters.

Purpose: To report an Australian series of macular hole surgery by pars plana vitrectomy and fluid-gas exchange, and to identify factors influencing the outcome of the surgery through meta-analysis of the literature.

Methods: Fifty-six consecutive cases of macular hole were treated by pars plana vitrectomy, fluid-gas exchange and face-down positioning for at least 7 days, and prospectively followed for 3-12 months. Thirty-six reports of macular hole surgery were reviewed.

Absence of ganglion cell subcomponents in multifocal luminance electroretinograms.

Aust N Z J Ophthalmol

May 1997

Electrophysiology Unit, Eye and Vision Research Institute, Sydney, New South Wales, Australia.

Multifocal flash electroretinograms (ERG) were recorded binocularly (n = 18). Areas were equal or scaled with excentricity. The latter were expected to increase the total amplitude if ganglion cell subcomponents were involved.

Purpose: This is the first report of the monitoring of the clinical progress of a central retinal vein occlusion by measuring the retinal venous collapse pressure using ophthalmodynamometry.

Method: A 38-year-old woman with a nonischaemic central retinal vein occlusion received systemic prednisone. The dose of prednisone was increased and decreased both abruptly and gradually.
