Clinical Diagnostic Testing

The full field ERG of a male affected by RS shows a selective reduction of the amplitude of the dark-adapted b-wave and a normal amplitude and latency of the a-wave, leading to a reduction of the b/a ratio.[13,14] Recently, the multifocal ERG (mfERG) has been introduced as a clinical test of central retina function. The mfERG can be helpful as a diagnostic test for RS in patients where a significant reduction of the b-wave amplitude cannot be demonstrated with a full field ERG. In one such case, the waveforms of the mfERG showed a reduction in amplitudes of the central waveforms.[14-16] Optical coherence tomography (OCT) is a new technique that allows one to view a two-dimensional profile of the macula. Areas of retinal schisis can be identified in multiple retinal layers by OCT in eyes with rs.[14,15,17,18] These OCT findings are in contrast to the previous clinical understanding that the schisis separation occurred only in the innermost retinal layers.

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
