TI  - Laser interferometry: preoperative functional predictive value in retinal 
      detachment.
PG  - 499-503
AB  - PURPOSE: To determine the functional predictive value of laser interferometry 
      (LI) in retinal detachment (RD). METHODS: Laser interferometry with test field 
      diameters of 3 degrees and 8 degrees, both with and without light, was tested 
      preoperatively in 42 eyes with rhegmatogenous RD that were candidates for scleral 
      buckling. Snellen visual acuity (VA) and LI (four test fields) were tested 
      preoperatively and postoperatively (1 week, and 1, 3, and 7 months). Sensitivity 
      and specificity of LI to predict postoperative (7 months after surgery) VA 
      improvement was calculated. Chi-square and Spearman correlation tests were used 
      for statistical analysis. RESULTS: Statistically significant Snellen VA 
      improvement (P = 0.02) was first found 7 months after surgery. Laser 
      interferometry at 3 degrees without light showed statistically significant 
      improvement 3 months after surgery (P = 0.05). Laser interferometry at 3 degrees 
      without light showed the highest sensitivity (93%) and specificity (87%) values. 
      The best correlation between preoperative LI and postoperative Snellen VA (7 
      months after surgery) was also found with 3 degrees LI without light (r = 0.71, P 
      = 0.002). CONCLUSION: Laser interferometry (3 degrees without light) was useful 
      in predicting VA improvement in cases with RD preoperatively and postoperatively. 
      Laser interferometry at 3 degrees without light showed the best correlation with 
      postoperative Snellen VA.
