evaluation of central corneal thickness measured by ultrasound pachymetry after vitrectomy with silicone oil
the central corneal thickness was measured by ultrasound pachymetry in 30 eyes of 30 patients with complex retinal detachment. All patients underwent vitrectomy with endolaser, silicone oil and cerclage.
All eyes underwent ultrasound pachymetry (ten measures were done each time) the day before, one week and one month after surgery.
the mean age was 55,6 years (±5,5). 53,3 % of patients were male and 60% were left eyes. The pachymetry measurements were 558µm±44.5 the day before, 595µm±40.5 at one week and 559µm±38.6 one month after surgery.
For the ten measurements with ultrasound pachymetry the standard deviation for each patient was 5.4 the day before surgery, 6.7 at one week and 6.9 at one month after surgery.
Significant difference was detected between pachymetry measurements the day before and at one week (p=0.0163). No significant difference was detected between pachymetry measurements the day before and at one month (p=0.85).
according to this study significant variation of central corneal thickness is detected at one week after vitrectomy with silicone oil, but there was no significant difference of central corneal thickness found at one month after vitrectomy with silicone oil.
