- Abstract
- AIM: To evaluate changes in subfoveal choroidal thickness (SFCT) and macular thickness as measured by enhanced depth imaging spectral -domain optical coherence tomography (EDI -OCT) after argon laser panretinal photocoagulation (PRP) in patients with severe diabetic retinopathy. METHODS: This prospective, comparative case series included 21 patients (28 eyes) with severe diabetic retinopathy. All patients underwent three sessions of PRP. The SFCT and macular thickness were measured using EDI -OCT at baseline and one week after completion of 3 sessions of PRP. RESULTS: SFCT before PRP was (318.1 +/- 96.5)mu m and increased to (349.9 +/- 108.3)mu m (P=0.001) after PRP. Macular thickness significantly increased at one week after PRP (from 273.1 +/- 23.9 mu m at baseline vs 295.8 +/- 25.3 mu m at one week; P<0.001). No significant relationship between the changes in macular thickness and SFCT was observed (r =-0.13, P =0.52). CONCLUSION: PRP induced increases in both SFCT and macular thickness. Changes in SFCT did not correlate with changes in macular thickness.
