We evaluated the effects of stellate ganglion block (SGB) on conjunctival oxygen tension, ocular surface temperature (n=7) and intraocular pressure (n=18) in patients with retinal vein occlusion and other retinopathy. The conjunctival oxygen tension (Pcj(O2)) increased from 45.6±5.0 mmHg to 76.3±19.9 mmHg in 45 minutes by SGB and then gradually returned to the control level. Pcj(O2) 120 minutes following SGB remained still at a higher level compared with the control value. Ocular surface temperature increased from 35.1±0.3°C to 35.9±0.3°C 25 minutes following SGB. Intraocular pressure decreased below the control level from 15 minutes to 120 minutes by SGB following an initial temporary increase. In conclusion, we have found that SGB does increase oxygen tension in ocular tissue and decrease IOP.
