Background: Diabetic retinopathy (DR) is a microvascular complication of diabetes, which is a cause of
visual impairment and blindness. Its development and progression have been linked to dyslipidaemia,
although the link remains inconclusive. Aim: This study aimed to determine the prevalence of
dyslipidaemia among type 2 diabetic patients with DR in a tertiary setting and to determine the association
between dyslipidaemia and DR severity. Materials and methods: This was a cross sectional study using
retrospective data of type 2 diabetic patients attending the opthalmology clinic of a tertiary centre from
January 2007 to June 2014. Results of their fasting lipid profile and clinical data were retrieved from
the hospital information system. Results: A total of 178 patient’s data were collected. 120 (n=67.4%)
patients had non-proliferative diabetic retinopathy (NDPR) with moderate NPDR being the most
prevalent. Dyslipidaemia was noted in 151 (84.8%) of the patients. Patients had a combination of more
than one abnormality in the lipid profile with increased LDL-cholesterol being the main abnormality.
Dyslipidaemia was however, not significantly associated with DR severity. Conclusion: Dyslipidaemia
was highly prevalent in DR patients. The dyslipidaemia was however not associated with severity of DR.

Diabetic retinopathy is a disease involving microangiopathic changes in response to chronic hyperglycaemia and pan
retinal photocoagulation (PRP) is currently the mainstay of treatment for proliferative retinopathy. In the present
study, we evaluated the effect of pan retinal photocoagulation (PRP) on retinal nerve fibre layer (RNFL) thickness in
patients with diabetic retinopathy using optical coherence tomography (OCT). This was a prospective longitudinal
study. Patients with Type 2 diabetes mellitus with proliferative diabetic retinopathy (PDR) or very severe non-
(N)PDR requiring laser treatment were included in the study. PRP was performed by a single trained personnel.
Peripapillary RNFL located 3.4 mm around the optic disc was evaluated using time-domain OCT. Examination was
performed before treatment, and 2 and 4 months after laser treatment. In total, 39 subjects (39 eyes) were recruited
into this study. Twenty-nine patients had PDR and 10 had very severe NPDR. Mean age was 54.97 ± 8.38 years.
Male and female genders were almost equally distributed with 18 males and 21 females. Median thickness of
average RNFL at baseline was 108.8 um (interquartile range [IQR] 35.3). At two months post-procedure, average
RNFL thickness significantly increased to 117.4 (IQR 28.6; P = 0.006). Although, other quadrants revealed a similar
trend of increasing thickness at two months but it was not significant. At 4 months post-laser treatment, RNFL
thickness in all quadrants reduced to baseline levels with insignificant changes of thickness compared to prior to
laser treatment. There was also no significant association between changes in RNFL thickness and HbA1c levels (P
= 0.77). In conclusion, PRP causes transient thickening of the RNFL which recovers within 4 months post-laser
treatment. At the same time, poor sugar control has no direct influence on the RNFL changes after PRP.

The purpose of this study is to evaluate the parameters of electroretinography[ERG]in eyes with diabetic retinopathy. The ERG responses were recorded in 46 normal subjects and 72 diabetic patients.We obtained the values of 12parameters from 5 basic responses and compared the changes of ERG parameters with the stages of diabetic retinopathy. The amplitude of oscillatory potentials decreased progressively from normal to severe nonproliferative diabetic retinopathy[NPDR].The b-wave implicit time of cone response was delayed in eyes with moderate NPDR to high risk proliferative diabetic retinopathy[PDR]. The b-wave amplitude of rod response was reduced in eyes with mild to moderate NPDR.The a-wave amplitude of maximal combined response significantly decreased between severe NPDR and early PDR.

7.Study on Retinal Circulation by Scanning Laser Ophthalmoscope I. Evaluation of Retinal Circulation Times in Non-proliferative Diabetic Retinopathy.
Journal of the Korean Ophthalmological Society 1995;36(7):1133-1136
The scanning laser ophthalmoscope was used to measure arm-retinal time(ART) and arteriovenous passage time(AVP) in 27 non-proliferative diabetic retinopathic eyes(NPDR eyes) and 22 normal controls. The ART in NPDR eyes(12.10 +/- 4.21 sec) was similar to that in normal eyes(12.79 +/- 3.59 sec). The AVPs measured from each quadrant were significantly longer in all quadrants in the NPDR eyes (2.41 +/- 0.85 sec in superior temporal quadrant (ST), 2.29 +/- 0.63 sec in inferior temporal one(IT) , 2.41+/-0.88 see in superior nasal one (SN), and 2.30 +/- 0.72 sec in inferior nasal one(IN)) than in normal eyes(1.73 +/- 0.61 sec in ST, 1.81 +/- 0.75 sec in IT, 1.83 +/- 0.58 sec in SN, and 1.83 +/- 0.58 sec in IN). This results suggest that retinal blood flow and its velocity are reduced in NPDR.

PURPOSE: To evaluation of the safety and the usefulness of our "You's bottle" that we have invented for sampling vitreous. METHODS: We performed the vitreous sampling with our collection bottle in 13 patients who had undergone vitrectomy for diabetic retinopathy. We observed the usefulness and complications after sampling. Collected vitreous was used for analysis of protein components. RESULTS: There was no complication associated with collection bottle. The analysis of proteome was successful. CONCLUSIONS: Our study showed that "You's bottle" might be a useful tool for the research of vitreous.

Author has studied photopic flash ERG for 27 control subjects and 28 patients with diabetic retinopathy and cataracts were excluded from the analysis. 1. In the 56 eyes of patients with diabetic retinopathy, 42 of them showed abnormal photopic 9ash ERG including 5 eyes which showed no consistent waveform. 2. There was significant difference in implicit time of a-and b-waves of photopic flash ERG between the control and diabetic retinopathy with cataract groups(p<0.01). 3. There was significant difference in amplitude of b-wave of photopic flash ERG between the control and diabetic retinopathy with cataract groups(p<0.01). 4. The abnormalities of photopic flash ERG had no significant correlation with the duration of Diabetes Mellitus and the severity of diabetic retinopathy.
