Appearance of an eye during intraoperative electroretinographic recordings.

<p>A contact lens with a built-in light-emitting diode (LS-100, Mayo Co, Inazawa, Japan) was sterilized and used as both the stimulus source and recording electrode for photopic ERGs.</p

Measurements of the amplitude and the latency of the oscillatory potentials (OPs).

<p>The amplitude (upper) and latency (lower) of each OP are shown. bar represents the beginning and duration of the stimulus flash.</p

The amplitude of each component and the intravitreal temperature before and after core vitrectomy.

<p>The amplitude of the on-PhNR, OP2, OP3, OP4, and OP5 decreases significantly after core vitrectomy. PhNR: photopic negative response, OP: oscillatory potential, bar indicates standard error. *<i>P</i> <0.05, **<i>P</i> <0.01, ***<i>P</i> <0.001.</p

The relationship between the change in the amplitude of each component and in the intravitreal temperature before and after core vitrectomy.

<p>No significant correlation was found in each relationship; amplitude change vs temperature change. There was a tendency for the amplitude in the d-wave and the off-PhNR to decrease with decreasing the temperature. Δ: the difference between pre- and post core vitrectomy that was determined as the value of the post vitrectomy minus that of the pre vitrectomy. PhNR: photopic negative response, OP: oscillatory potential,</p

The relationship between the change in the latency of each component and in the intravitreal temperature before and after core vitrectomy.

<p>No significant correlation was found in each relationship; latency change vs temperature change. There was a tendency for the latency in the a- and d-waves and the off-PhNR to be prolonged and for the latency in the b-wave to be shortened with decreasing the temperature. Δ: the difference between pre- and post core vitrectomy that was determined as the value of the post vitrectomy minus that of the pre vitrectomy. PhNR: photopic negative response, OP: oscillatory potential.</p

Changes of the electrophisiologic parameters and the intravitreal temparature before and after core vitrectomy.

Appearance of the eye during intravitreal temperature recording.

<p>The tip of a 26-gauge flexible wire thermoprobe (MT-26, Phisitemp, New Jersey USA) was inserted through trocar and placed in the midvitreous cavity. The thermoprobe was connected to a battery-operated thermometer device (Phisitemp BAT-12, New Jersey USA).</p
