چکیده
normal 0 false false false en-us x-none ar-sa background: we aimed to compare peak systolic velocity of central retinal artery (psv.cra) and peak systolic velocity of ophthalmic artery (psv.oa) between patients with retinal detachment who were treated with segmental scleral bucking and scleral buckling with encircling procedure. materials and methods: this study was a descriptive-analytic cross sectional study that was performed in isfahan university referral centers since april 2010 to april 2011. of the patients who have undergone scleral buckling surgery, 20 patients belonging to two groups were randomly selected to enroll in the study. study groups were, patients who have undergone segmental scleral buckling and the other group were patients who have undergone scleral buckling with encircling procedure. patients were invited to perform color doppler imaging. psv-ra and psv-oa were measured and documented in both operated and unoperated eyes. all of the doppler’s performed at least three months after ophthalmic surgery. results: we found significant decrease in psv.cra among patients in both groups. in patients who had undergone scleral buckling with encircling procedure psv.cra was 11.03 ± 3.04 (cm/sec) and 14.83 ± 4.80 in operated and unoperated eye respectively ( p = 0.03). in other hand, who treated with segmental scleral buckling these parameters were 11.02 ± 2.48 and 14.45 ± 4.69 ( p = 0.03). psv.oa did not change significantly in each method. the difference between mean psv.cra and psv.oa in operated eye between two study groups was not significant. conclusion: psv.cra reduced significantly in both surgery methods and psv.oa changes was not significant. however, the mean psv.cra and psv.oa changes did not show statistically significant difference between surgery methods.

متن کاملRetinal blood flow alterations associated with scleral buckling and encircling procedures.
The bidirectional laser Doppler technique and monochromatic photography were used to measure the absolute blood flow rate in the major temporal retinal arteries in seven patients following unilateral scleral buckling and encircling procedures, and in two patients before and after removal of scleral buckling elements. In the seven patients who had undergone uncomplicated scleral buckling procedu...

THE past few years have seen the rapid development of scleral buckling procedures for the treatment of retinal separation (Cavka, 1959; Schepens, Okamura, and Brockhurst, 1957; Schepens, Okamura, Brockhurst, and Regan, 1960; Fison, McAuley, Meyer-Schwickerath, and Trevor-Roper, 1960). About 6 years ago I first used the lamellar scleral flap to cover the area of resection. The flap covered the k...
