Description
Summary:AIM: To investigate the effects of selective laser trabeculoplasty(SLT) on the main numerical parameters of anterior segment with Pentacam rotating Scheimpflug camera in patients with ocular hypertension(OHT) and primary open angle glaucoma(POAG).·METHODS: Pentacam measurements of 45 eyes of 25(15 females and 10 males) patients(12 with OHT, 13 with POAG) before and after SLT were obtained.Measurements were taken before and 1 and 3mo after SLT. Pentacam parameters were compared between OHT and POAG patients, and age groups(60y and older, and younger than 60y).·RESULTS: The mean age of the patients was 57.8±13.9(range 20-77y). Twelve patients(48%) were younger than60 y, while 13 patients(52%) were 60 y and older.Measurements of pre-SLT and post-SLT 1mo were significantly different for the parameters of central corneal thickness(CCT) and anterior chamber volume(ACV)(P <0.05). These parameters returned back to preSLT values at post-SLT 3mo. Decrease of ACV at post-SLT 1mo was significantly higher in younger than 60 y group than 60 y and older group. There was no statistically significant difference in Pentacam parameters between OHT and POAG patients at pre- and post-treatment measurements(P >0.05).·CONCLUSION: SLT leads to significant increase in CCT and decrease in ACV at the 1st month of the procedure. Effects of SLT on these anterior segment parameters, especially for CCT that interferes IOP measurement, should be considered to ensure accurate clinical interpretation.
