To quantitatively assess changes in the anterior chamber angle,in eyes undergoing retinal detachment surgery with placementof scleral explant
In this prospective case series, 40 eyes of 40 patients witha phakic Rhegmatogenous Retinal Detachment who underwent retinaldetachment buckling surgery with placement of encirclage wereevaluated. All eyes underwent preoperative IOP assessment usingGoldmann Applanation Tonometry and evaluation of the nasal andtemporal anterior chamber angles using ASOCT which were repeatedat 48 hrs and 1 week post surgery. The parameters noted n ASOCTwere: Trabecular Iris Angle ( TIA) , Angle opening distanceat 500 µm(AOD 500) and Trabecular Iris Surface Area 500µm ( TISA 500). Measurements were taken nasally (0º)and temporally (180º)
The mean age was 43.2 years± 18.3 years , there were28 males and 12 females. The changes in IOP and angle parametersare given in Table 1. There was statistically significant narrowingof all angle parameters and rise of intraocular pressure inall cases in the immediate postoperative periodThe correlationbetween change in IOP and change in angle parameters at 48 hoursand at 1week is given in Table 2 as follows
Retinal Detachment surgery with scleral explant causes significantnarrowing of anterior chamber angle parameters and rise of IOPin the early postoperative period .
