Abstract

A new, compact optical instrument developed in clinical work is presented and its optical properties are discussed: it allows simultaneous viewing of a patient's fundus and its fluorescein angiography. Both stereo and mono angiography can be superimposed in the slit lamp in a 1-to-1 juxtaposition of fundus topography and angiogram. In this way very precise transfer of angiographical data is possible. Safety during laser coagulation is increased, and the size of iatrogenic scotomas is thus reduced. The instrument is described, and image superimposition illustrated with clinical examples.

Horseshoe-like macular tear following recurrent branch retinal vein occlusion.

BACKGROUND: A macular hole can develop as a late complication secondary to a branch retinal vein occlusion (BRVO). We report about an atypical horseshoe-like tear occurring in the fovea after recurrent BRVO. METHODS: An interventional case report. RESULTS: In 1997, a 53-year-old man was seen with an occlusion of macular part of inferior temporal vein of the retina on the left eye. After experiencing several recurrent BRVO in this eye, 6 years later he presented with a horseshoe-like tear in the fovea. Visual acuity was 20/200. The patient underwent standard three-port vitrectomy and installation of C3F8 16%. Intraoperatively, massive traction of the vitreous was detected on the edges of the tear. Six months after the operation, the tear remained attached. The visual acuity was 20/200. CONCLUSIONS: The uniqueness of the presented case is the occurrence of a macular tear following recurrent BRVO, its horseshoe-like shape and foveal location. To the best of our knowledge, this is the first report on a horseshoe-like tear seen in the fovea secondary to BRVO. We assume that chronic macular edema and retinal ischemia following BRVO were additional factors beside the vitreous traction, contributing to the formation of the macular tear. Anatomical closure of the tear and stabilisation of visual acuity can be achieved by vitreoretinal surgery.
