    Measuring the refractive properties of the diabetic eye during blurred vision and hyperglycaemia using aberrometry and Scheimpflug imaging

    ACTA OPHTHALMOLOGICA, Issue 2 2009
    Nanouk G. M. Wiemer
    Abstract. Purpose:, This study aimed to measure the refraction and geometry in the diabetic eye during the presence and absence of hyperglycaemia and blurred vision, using aberrometry and Scheimpflug imaging. Methods:, Aberrometry and Scheimpflug imaging were used to examine ocular refraction and higher-order aberrations, as well as the shape of the cornea and the lens, in 25 patients with diabetes mellitus. From these parameters, the equivalent refractive index of the lens was calculated. Using paired t -tests, comparisons were made between a first series of measurements (Visit 1) taken in the presence of blurred vision and hyperglycaemia (> 10.0 ,mol/l), and a second series of measurements (Visit 2) taken under normal conditions. Results:, The mean difference in blood glucose between Visits 1 and 2 was 5.9 mmol/l (standard deviation [SD] 3.1) (p < 0.0001). Both small hyperopic and myopic shifts of equivalent refractive error (ERE) were found in nine patients (mean absolute difference ERE: 0.38 D [SD 0.12]; p = 0.02). Furthermore, higher-order aberrations (root mean square [RMS] error) were slightly increased in four patients (mean difference RMS error: 0.07 ,m [SD 0.02]; p = 0.04) at Visit 1, compared to Visit 2. No significant changes were observed in the shape of the cornea or lens in any of the patients. No significant correlations were found between changes in blood glucose levels and the measured parameters in diabetic eyes. Conclusions:, The present study suggests that subjective symptoms of blurred vision during hyperglycaemia are not necessarily caused by changes in the refractive properties of the diabetic eye.

    Quantitative assessment of retinal thickness in diabetic patients with and without clinically significant macular edema using optical coherence tomography

    ACTA OPHTHALMOLOGICA, Issue 3 2001
    Chang-Sue Yang
    ABSTRACT. Purpose: To assess patients with diabetic macular edema quantitatively using optical coherence tomography (OCT). Methods: OCT was performed in 14 eyes with diabetic retinopathy and ophthalmoscopic evidence of clinically significant macular edema (CSME) and in 19 diabetic eyes without CSME. Retinal thickness was computed from the tomograms at fovea and other 36 locations throughout the macula. Results: The mean±standard deviation foveal thickness was 255.6±138.9 ,m in eyes with CSME, and 174.6±38.2 ,m in eyes without CSME (p=0.051). Within 2000 ,m of the center of the macula, eyes with CSME had significantly thicker retina in the inferior quadrant than those without CSME (p<0.01). The foveal thickness was correlated with logMAR visual acuity (,=0.68, p<0.01). OCT identified sponge-like retinal swelling and/or cystoid macular edema in 11 (58%) eyes without CSME, and in 12 (86%) eyes with CSME. Conclusions: Criteria of CSME seem to be insufficient in really identifying macular edema. OCT may be more sensitive than a clinical examination in assessing diabetic macular edema and is a quantitative tool for documenting changes in macular thickening. [source]

    Hemostatic effects of SF6 after diabetic vitrectomy for vitreous hemorrhage

    ACTA OPHTHALMOLOGICA, Issue 1 2001
    CH. N. Koutsandrea
    ABSTRACT. Purpose: To investigate the hemostatic effects of SF6 gas in preventing postoperative vitreous hemorrhage in diabetic vitrectomy. Methods: A prospective, randomized study of 33 diabetic eyes with vitreous hemorrhage, treated by vitrectomy. In 17 of our cases SF6 20% was injected into the eye at the end of the operation, while in 16 cases BSS remained in the vitreous cavity. Results: The incidence of vitreous hemorrhage recurrence was 17.6% for the SF6 group and 12.5% for the BSS group (statistically not significant). Progression of lens opacities was observed in 23.5% of the SF6 group, and in 18.8% of the BSS group (statistically not significant, with a higher incidence in the SF6 group). Conclusions: SF6 gas did not show hemostatic effects in the cases studied. Furthermore, it may have contributed to cataract progression. Therefore we suggest that the use of SF6 is not recommended as a treatment modality in preventing new vitreous hemorrhage after diabetic vitrectomy. [source]

    Avastin as an adjunct to vitrectomy in the management of severe proliferative diabetic retinopathy: a prospective case series

    CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 5 2008

    Abstract Purpose:, Bevacizumab (Avastin) is a monoclonal antibody which targets all isoforms of vascular endothelial growth factor A. Its potent anti-angiogenic effects have been shown to cause regression of neovascularization in proliferative diabetic retinopathy. The aim of this study is to investigate the role of Avastin as an adjunct to vitrectomy in the management of severe diabetic eye disease. Methods:, Sixteen patients (18 eyes) with severe proliferative diabetic retinopathy were recruited into the study. All eyes underwent a single intravitreal injection of bevacizumab 1.25 mg in 0.05 mL prior to vitrectomy surgery for the management of tractional retinal detachment or vitreous haemorrhage due to severe proliferative diabetic retinopathy. Results:, At 3 months, seven eyes had visual acuities which were better than baseline, four were unchanged and seven were worse. At 6 months, 14 eyes had visual acuities better than baseline, one was unchanged and three were worse. Seven of the 18 eyes (38.8%) had postoperative rebleeds, six of which required surgical washout. Conclusion:, Avastin improved the ease of the surgery in these complex eyes and the early results are encouraging. We have found it to be particularly useful in diabetic eyes with traction detachments of short duration in which there is still active neovascularization. [source]
