ABSTRACT

@#AIM: To observe the efficacy of addition and subtraction of Buyang Huanwu decoction in the adjuvant treatment of non-proliferative diabetic retinopathy of Qi-Yin deficiency and blood stasis and its effects on traditional Chinese medicine(TCM)syndromes and visual function level. <p>METHODS: A total of 110 patients with non-proliferative diabetic retinopathy of Qi-Yin deficiency and blood stasis in our hospital between January 2017 and December 2019 were selected and divided into observation group(55 cases, 110 eyes)and control group(55 cases, 110 eyes). Patients in control group received conventional treatment according to the condition of patients with reference to relevant guidelines, and patients in observation group were combined with addition and subtraction of Buyang Huanwu decoction adjuvant therapy on this basis. The clinical efficacy after 3mo of treatment, and TCM syndromes scores, clinical indicators(macular edema score, macular retinal volume, macular foveal retinal thickness), visual function(best corrected visual acuity, average visual field sensitivity)and serum biochemical indicators \〖vascular endothelial growth factor(VEGF), hypoxia-inducible factor-1(HIF-1)\〗 before treatment and 3mo after treatment were compared between the two groups.<p>RESULTS: After 3mo of treatment, the total effective rate of treatment in observation group was significantly higher than that in control group(<i>P</i><0.05). After 3mo of treatment, the TCM syndromes scores in the two groups were decreased compared with those before treatment, and the scores in observation group were lower than those in control group(<i>P</i><0.05). After 3mo of treatment, the macular edema score, macular retinal volume and macular foveal retinal thickness in the two groups were reduced compared with those before treatment, and the indexes in observation group were smaller than those in control group(<i>P</i><0.05). After 3mo of treatment, the best corrected visual acuity and average visual field sensitivity in the two groups were improved compared with those before treatment, and the indexes in observation group were higher than those in control group(<i>P</i><0.05). After 3mo of treatment, the levels of serum VEGF and HIF-1 in the two groups were decreased compared with those before treatment, and the levels in observation group were lower than those in control group(<i>P</i><0.05). <p>CONCLUSION: Addition and subtraction of Buyang Huanwu decoction has an exact efficacy in the adjuvant treatment of non-proliferative diabetic retinopathy of Qi-Yin deficiency and blood stasis, and it can improve symptoms and promote visual function recovery by reducing the expressions of VEGF and HIF-1.

ABSTRACT

Diabetic retinopathy (DR) is a major microvascular complication of diabetes. It is the most common cause of blindness in the working-age population in developed countries. We wanted to analyse the correlation between risk factors of blindness like duration of diabetes, dyslipidaemia, hypertension, HbA1c with severity of diabetic retinopathy in order to design appropriate strategies for prevention and treatment of diabetic retinopathy.METHODSThis was a retrospective study of all diabetic patients with diabetic retinopathy who presented to the eye OPD at KS Hegde Medical Academy from April 1st 2018 to March 31st 2019 that fulfilled the inclusion criteria. A dilated fundus examination was done to note the grade of diabetic retinopathy. The demographic data along with the duration of diabetes, HbA1c values, Cholesterol levels and Blood pressure were documented and correlated with the severity of diabetic retinopathy.RESULTSThe study included 92 patients, of which 63 were males and 29 were females with a mean age of 54.5±2.8 years. We found that there was statistically significant association between the duration of diabetes and HbA1c levels with severity of diabetic retinopathy (p= 0.022 and 0.034 association), whereas there was no statistically significant correlation between blood pressure and cholesterol levels with severity of diabetic retinopathy (p= 0.52 and 0.456 respectively)CONCLUSIONSDiabetic retinopathy showed a male preponderance, with risk factors like duration of diabetes and HbA1c levels having a significant association with the severity of diabetic retinopathy. Therefore, it is essential to have a good systemic control of diabetes with diet and suitable medications. Diabetic retinopathy is a preventable cause of blindness when diagnosed early and screening of diabetic retinopathy must be done in all diabetics to prevent the progression of the disease.

ABSTRACT

@#AIM: To investigate the timing of using anti-VEGF drugs in severe non-proliferative diabetic retinopathy(SNPDR)patients with diabetic macular edema(DME)treated with intravitreal injection of Conbercept(IVC)combined with panretinal photocoagulation(PRP). <p>METHODS: Totally 85 SNPDR patients(85 eyes)with DME diagnosed in our hospital from May 2017 to October 2018 were randomly divided into control group(<i>n</i>=29 cases), IVC group(<i>n</i>=28 cases), PRP group(<i>n</i>=28 cases). The control group was treated with PRP only; the IVC group was given PRP 1wk after IVC; the PRP group was given IVC 1wk after PRP. The follow-up time was 12mo. Changes of the best corrected visual acuity(BCVA)and central macular thickness(CMT)were observed before and 1, 3, 6, 12mo after treatment, and the frequency of IVC were recorded.<p>RESULTS: Compared with before treatment, the BCVA of the three groups after treatment improved, and the CMT decreased(<i>P</i><0.05). after treatment, the BCVA of the IVC group and the PRP group was better than the control group, and the CMT was lower than the control group(<i>P</i><0.05). 3mo after treatment, BCVA(0.24±0.18, LogMAR)in the ICV group decreased more than that in the PRP group(0.38±0.29, LogMAR)(<i>P</i><0.05). At 1 and 3mo after treatment, CMT in the ICV group(1mo 313.89±61.69um, 3mo 287.64±43.94μm)decreased more than that in the PRP group(1mo 347.50±56.55μm, 3mo 318.04±49.334μm), and the difference was significant difference(<i>P</i><0.05). The frequency of IVC was(3.07±1.33)times in the IVC group and(3.93±1.60)times in the PRP group(<i>P</i><0.05).<p>CONCLUSION: In SNPDR patients with DME, IVC combined with PRP is better than PRP alone. Anti-VEGF drugs before PRP can obtain better BCVA, reduce macular edema in the short-term observation. In long-term observation, it can also reduce the frequency of IVC, the risk of infection and the financial burden.

ABSTRACT

@#AIM: To analyse the characteristic of macular microcirculation detected by optical coherence tomography angiography(OCTA)in nonproliferative diabetic retinopathy(NPDR).<p>METHODS: Vessel density of 3mm×3mm centered on the fovea(3mm×3mm VD), parafoveal vessel density(parafoveal VD)and foveal vessel density(foveal VD)were measured by OCTA in healthy people, NDR, mild NPDR, moderate NPDR, and severe NPDR groups. <p>RESULTS: Deep 3mm×3mm VD, deep parafoveal VD and deep foveal VD were decreased gradually in groups. There was statistically significant difference between moderate NPDR, severe NPDR and others in deep 3mm×3mm VD and parafoveal VD(<i>P</i><0.01). There was statistically significant difference between severe NPDR and control group in deep foveal VD(<i>P</i>=0.006). Superficial 3mm×3mm VD and superficial parafoveal VD are statistically significant in groups. There was statistically significant difference between moderate NPDR group and control group in superficial 3mm×3mm VD and parafoveal VD(<i>P</i><0.01). There was statistically significant difference between severe NPDR group and others except moderate NPDR group in superficial 3mm×3mm VD, parafoveal VD(<i>P</i><0.01). There was a significant correlation of deep and superficial 3mm×3mm VD,deep and superficial parafoveal VD, deep parafoveal VD with VA.<p>CONCLUSION: Deep vessel density decreased more significantly in moderate NPDR and severe NPDR groups and deep parafoveal vessel density might be a potential biomarker of DR.

ABSTRACT

PURPOSE: We report a case of rapid progression to proliferative diabetic after generalized edema occurrence in a non proliferative diabetic retinopathy patient. CASE SUMMARY: A 48-year-old man visited our hospital with both eyes visual disturbance which occurred 1 week ago. He was diagnosed with moderate non proliferative diabetic retinopathy 5 months ago and there was no significant interval change 3 weeks ago. Date of visit, diffuse macular edema and neovascularization were observed in both eyes. Accompanying visual disturbance, he had generalized edema and 10 kg of weight gain. We thought it was not common diabetic macular edema, we held ophthalmic treatment such as an intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection and requested medical treatment to the department of nephrology. Diagnosed with aggravation of left ventricle heart failure and diabetic nephropathy, he took diuretics and low salt diet for 10 days. After 10 days, his visual acuity improved and macular edema disappeared. Since then, he received intravitreal anti-VEGF injection and panretinal photocoagulation for proliferative diabetic retinopathy treatment. Nevertheless, he underwent pars plana vitrectomy due to vitreous hemorrhage in right eye. CONCLUSIONS: We experienced a case of sudden diffuse macular edema and progression to proliferative diabetic retinopathy associated with generalized edema. We suggest that it is necessary to consider systemic changes in diabetic retinopathy.

ABSTRACT

@#AIM: To further investigate the etiology and treatment strategies of diabetic macular edema(DME)by studying the correlation between responses to intravitreal injection of Ranibizumab(IVR)and diabetic retinopathy(DR)extent in DME patients. <p>METHODS: This study comprised 33 eyes of 27 non proliferative diabetic retinopathy(NPDR)patients with DME and 34 eyes of 32 PDR patients with DME, who had been followed for at least 6mo after IVR. We compared the responses to the anti-VEGF treatment between the two groups. <p>RESULTS: NPDR patients had strong statistical improvement in best corrected visual acuity(BCVA)and central macular thickness(CMT)after both 3-month treatment and 6-month treatment(<i>P</i><0.05), While PDR patients had not(<i>P</i>>0.05). There were also statistical differences(<i>P</i><0.05)in BCVA and CMT between NPDR group and PDR at a time when the patients had received both 3-month treatment and 6-month treatment. <p>CONCLUSION: Different extents of DR have influence on DME responses to anti-VEGF.

ABSTRACT

@#AIM: To investigate the clinical effect of Qi Ming granule combined with calcium dobesilate in treatment of non-proliferative diabetic retinopathy(NPDR).<p>METHODS: Totally 94 patients with I~III stage NPDR in our hospital from January 2014 to May 2016 were collected and randomly divided into control group and observation group, all were unilateral, with 47 eyes in each group. The two groups were given control of blood glucose, diet and exercise therapy and other conventional treatment. The control group were treated with conventional western medicine calcium dobesilate treatment, 0.5g,3 times per day, the observation group combined with Qi Ming granule treatment based on control group treatment. Both groups were treated for 3mo. Two groups were observed before and after treatment for visual sensitivity and changes of serum cytokines \〖vascular endothelial growth factor(VEGF)and insulin-like growth factor-1(IGF-1), pigment epithelium derived factor(PEDG)\〗. Therapeutic effect and safety of the two groups were comprehensively evaluated and compared. <p>RESULTS: The average sensitivity of the observation group after treatment was lower than that before treatment and the control group after treatment, the difference were statistically significant(<i>P</i><0.05).The VEGF,IGF-1,PEDG of observation group after treatment, were significantly improved compared with the control group, the difference were statistically significant(<i>P</i><0.05). There were no obvious adverse reactions in the two groups, the total effective rate was 89% in the observation group, which was higher compared with the control group 72%, and the difference was statistically significant(<i>P</i><0.05). <p>CONCLUSION: Qi Ming granule combined with western medicine in the treatment of DR can effectively improve the function of the retina and ease the progress of the disease, and the safety is good, the clinical treatment effect is remarkable.

ABSTRACT

AIM: To investigate the effects of external counterpulsation combined with laser photocoagulation for treatment of non-proliferative diabetic retinopathy. METHODS: A prospective study method were used from Aug. 2013 to Feb. 2016. A total of 104 cases in our hospital for treatment of non - proliferative stage of diabetic retinopathy patients were selected as the research object, and all the patients were equally divided into observation group and control group, 52 cases in each group according to the order of admission. Patients in control group were treated with panretinal laser photocoagulation treatment. The observation group were given external counterpulsation combined with laser photocoagulation for treatment, observed the prognosis in the two groups. RESULTS: The total efficiency in the observation group and the control group were 98. 1% and 84. 6%, the observation group was significantly higher than the control group (P0. 05). CONCLUSION: External counterpulsation combined with laser photocoagulation treatment has good safety in the treatment of non-proliferative diabetic retinopathy, it can promote eye artery blood flow speed, thereby improve the therapeutic effect.

ABSTRACT

Diabetic retinopathy (DR) may result in progressive visual impairment and blindness which affects the diabetic patients‟ morbidity and quality of life significantly. The objective of this study was to determine the proportions and prognostic factors of DR severity among Type 2 diabetes mellitus patients. A cross sectional study was conducted at the Ophthalmology Clinic in a tertiary hospital using the medical record database from 2005 to 2011. A total of 216DR patients were randomly selected. The study outcome was DR severity which was classified into four grading based on the International Clinical Diabetic Retinopathy Scale. Descriptive statistics and Ordinal Logistic Regression were applied using Stata SE/11. The mean (SD) age of DR in this study was 56.06 (9.98) years old with almost equal sex ratio. Proportion of mild non proliferative diabetic retinopathy (NPDR) was 48.6% (95% CI: 40.0, 60.0), moderate NPDR was 28.2% (95%CI: 22.0, 40.0), severe NPDR was 6.9% (95% CI: 4.0, 11.0) and proliferative diabetic retinopathy (PDR) was 16.2% (95%CI: 10.0, 22.0). Diabetic patients that suffered from diabetes mellitus for more than 10 years, having nephropathy, every increased of HbA1c by 1% and higher total cholesterol were at increased risk of worsening DR.
