Purpose:
|
to investigate the peripapillary retinal thickness
in ischemic and non-ischemic central retinal vein occlusion (CRVO).
|
|
Methods:
|
In this cross-sectional study 40 patients with diagnosis of CRVO were included. They were considered as Ischemic CRVO if they met two of these criteria: 1-
VA ≤ 1/10 2-RAPD ≥ 2+ 3-Capillary non perfusion ≥ 10 disc area in FA. Then peripapillary and macular retinal thickness was measured using optic nerve head and macular OCT respectively. Statistical analysis was performed to compare peripapillary retinal thickness as well as central retinal thickness between two groups.
|
|
Results:
|
: Mean VA in ischemic and non-ischemic type was 1.7 ± 0.64 and 0.67 ± 0.45 LogMAR respectively (P< 0.0001). In optic nerve head OCT, average peripaillary thickness was 594 ± 156.5 ?m in ischemic type patients while it was 424 ± 117.3 ?m in non-ischemic type (p=0.001). Mean central retinal thickness in ischemic and nonischemic type was measured 696.4 ± 294.8 and 508 ± 167.9 ?m respectively (P=0.023).
Mean retinal volume in ischemic type was measured to be greater than in non-ischemic type (13.92 ± 3.7 compared to 11.48 ± 1.7, P=0.014).

|
Conclusion:
|
OCT values of paripapillary retinal thickness might help to distinguish between two types Of CRVO.
