    Central corneal thickness in type II diabetes mellitus: is it related to the severity of diabetic retinopathy?

    Background/aim: To compare the central corneal thickness (CCT) of type II diabetes mellitus patients with age- and sex-matched healthy subjects and to determine the association of the severity of diabetic retinopathy and CCT. Materials and methods: Type II diabetes mellitus patients without retinopathy, with nonproliferative retinopathy, and with proliferative retinopathy were organized as the three subgroups of the study group, and an age-and sex-matched control group was formed. All subjects underwent full ophthalmological examination and CCT measurement with ultrasonographic pachymetry. CCT values were compared between diabetic and healthy subjects and between the three diabetic subgroups. Correlation analysis was performed to determine any relationship between CCT and intraocular pressure. Results: The average CCT was significantly higher in diabetic patients than in the control group (P = 0.04). CCT in diabetic patients without retinopathy did not significantly differ from that of patients with retinopathy (P = 0.64). Similarly, there was no significant difference in CCT between nonproliferative and proliferative diabetic retinopathy patients (P = 0.47). In the whole study population, CCT was significantly correlated with intraocular pressure (P < 0.01). Conclusion: CCT is significantly increased in type II diabetes mellitus patients with respect to controls. Retinal disease severity does not seem to have an effect on corneal thickness.

    AIM: To evaluate central macular thickness (CMT) and mean choroidal thickness (MCT) in eyes with branch retinal vein occlusion (BRVO), before and after ranibizumab treatment using spectral domain -optical coherence tomography (SD-OCT). METHODS: Forty -two patients with unilateral BRVO and macular edema were included in this study. There were 25 men and 17 women. Using SD-OCT, choroidal thickness was measured at 500 mu m intervals up to 1500 mu m temporal and nasal to the fovea. MCT was calculated based on the average of the 7 locations. All the eyes with BRVO were treated with intravitreal ranibizumab (0.5 mg/0.05 mL). Comparisons between the BRVO and fellow eyes were analyzed using Mann-Whitney test. Pre-injection and post-injection measurements were analyzed using Wilcoxon test and repeated measure analysis. RESULTS: At baseline, there was a significant difference between the BRVO and fellow eyes in MCT [BRVO eyes 245 (165-330) mu m, fellow eyes 229 (157-327) mu m] and CMT [BRVO eyes 463 (266-899) mu m, fellow eyes 235 (148-378) mu m (P=0.041, 0.0001, respectively)]. Following treatment, CMT [295 (141-558) mu m] and MCT [229 (157329) mu m] decreased significantly compared to the baseline measurements (P=0.001, 0.006, respectively). Also BCVA (logMAR) improved significantly (P=0.0001) in the BRVO eyes following treatment. After treatment CMT [BRVO eyes 295 (141-558) mu m, fellow eyes 234 (157-351) mu m] and MCT [BRVO eyes 229 (157-329) mu m, fellow eyes 233 (162-286) mu m] values did not reveal any significant difference in BRVO eyes and fellow eyes (P=0.051, 0.824, respectively). CONCLUSION: In eyes with BRVO, CMT and MCT values are greater than the fellow eyes, and decrease significantly following ranibizumab injection.
