PURPOSE: To evaluate the @entity3193 in the subfoveal region quantitatively after panretinal photocoagulation (PRP) in eyes with severe nonproliferative @entity6 . METHODS: This was a prospective comparative study of 24 eyes of 24 @entity1 with @entity2175 and severe nonproliferative @entity6 with no macula @entity4 . The foveal retinal thickness and @entity3193 were measured by enhanced depth imaging optical coherence tomography. The subfoveal choroidal blood flow was represented by the mean blur rate obtained by laser speckle flowgraphy. The intraocular pressure, blood pressure, pulse rate, and hemoglobin A1c level (HbA1c) were also measured before and after PRP. RESULTS: The mean foveal retinal thickness did not change significantly during the follow-up period. The mean subfoveal @entity3193 was reduced significantly from 327.4  m at the baseline to 286.3  m at 1 month and 285.0  m at 3 months after PRP. The mean blur rate ratio decreased significantly to 87.5% at 1 month and 86.0% at 3 months of the baseline values. There was a significant correlation between the subfoveal @entity3193 after PRP. After PRP, the best-corrected visual acuity, intraocular pressure, mean arterial pressure, ocular perfusion pressure, pulse rate, and HbA1c did not change significantly. CONCLUSION: The success of PRP in treating eyes with severe nonproliferative @entity6 is probably due to the significant reduction of the subfoveal @entity3193 after PRP.
