4.Effect of Prior Cataract Surgery on the Clinical Outcome of Selective Laser Trabeculoplasty.
Journal of the Korean Ophthalmological Society 2015;56(6):911-916
PURPOSE: To compare the efficacy of selective laser trabeculoplasty (SLT) in phakic and pseudophakic eyes in primary open-angle glaucoma. METHODS: Charts of 55 phakic eyes and 24 pseudophakic eyes that underwent 360-degree SLT were retrospectively reviewed. Intraocular pressure (IOP) was measured before SLT and 1 week, 1, 3, 6, 9, 12, 18 and 24 months after SLT. Treatment success was defined as IOP reduction > or = 20% without additional medications, laser or glaucoma surgery. Mean IOP change, mean percentage of IOP reduction and success rates of phakic and pseudophakic eyes were compared. RESULTS: Mean percentage of IOP reduction after SLT at 1 week and 1, 3, 6, 9, 12, 18, and 24 months were 18.8%, 23.9%, 24.6%, 23.3%, 24.0%, 22.1%, 20.8%, and 17.9%, respectively, in the phakic group and 15.7%, 22.3%, 23.7%, 25.3%, 25.6%, 25.2%, 21.9%, and 19.3%, respectively, in the pseudophakic group. Success rates were 57.6 +/- 11.9% in the phakic group and 61.3 +/- 10.4% in the pseudophakic group. No statistically significant differences in IOP change, percentage of IOP reduction, and success rates were observed between the groups at each time point after SLT (p > 0.05). CONCLUSIONS: Application of 360-degree SLT appears an efficient treatment option for the management of phakic and pseudophakic open-angle glaucoma. Evaluating the success of SLT 1 month postoperatively may be premature.

6.A Case of Central Serous Chorioretinopathy after Glaucoma Filtering Surgery.
Journal of the Korean Ophthalmological Society 2014;55(12):1895-1900
PURPOSE: To report a case of central serous chorioretinopathy development after glaucoma filtering surgery and spontaneous resolution in a patient with a history of central serous chorioretinopathy in the contralateral eye. CASE SUMMARY: A 46-year-old male with a history of chronic uveitis in both eyes presented with uncontrolled intraocular pressure (IOP) in his left eye. Initial IOP was 34 mm Hg in his left eye. On preoperative evaluation, central serous chorioretinopathy, which was diagnosed in another clinic 1 month prior, was observed in his right eye. Slightly pale optic disc and retinal nerve fiber layer defects were noted in the left eye. However, macular abnormalities were not observed in the left eye. Trabeculectomy and peripheral iridectomy using mitomycin C were performed in the left eye. The patient was prescribed triamcinolone 8 mg daily for 4 days to reduce the post-surgical inflammation. On postoperative day 4, IOP in the left eye was 7 mm Hg and newly developed central serous chorioretinopathy was noted. On follow-up, IOP was maintained at 7-10 mm Hg and central serous chorioretinopathy disappeared 7 months postoperatively. CONCLUSIONS: When clinicians consider performing an ophthalmological procedure in a patient with a history of central serous chorioretinopathy in the contralateral eye, careful observation of central serous chorioretinopathy development is recommended.

The effect of persistant mild hyperglycemic hyperinsulinemia on the development of the insulin resistance in rats was studied in vivo. Also, the characteristics of the insulin resistance compared with the insulin resistance of STZ diabetic rats. Persistant mild hyperglycemic hyperinsulinemic rat model was produced by ingestion of glucose polymer for 8 days. The glucose disappearance and infusion rate was measured by hyperinsulinemic euglycemic clamp to"Imique at steady state of blood glucose and insulin levels. The clamped level of blood glucose was 100 mg/dl, and the clamped levels of insulin were 70 pU/ml (physiologic condition) and 3000 pU/ml (supramaximal condition). Hepatic glucose producticon rate was calculated using measured data. And the glycogen synthetic capacity of skeletal muscle(soleus) and liver was measured after 2 hours of hyperinsulinemic euglycemic clamp study. The glucose disappearance and glucose infusion rate in glucose polymer group was decreased in the both physiological and supramaximal insulin level compared to the rate of the normal control group. The rate of STZ diabetic group wase lowest at supramaximal insulin level among two another experimental groups. The hepatic glucose production rate of glucose polymer group was decreased compared to normal control but increased in STZ diabetic group.

Phylloides tumor is very similar to giant fibroadenoma in that they have benign appearance in breast radiologic image. Fibroadenoma has no malignant potential, but phylloides tumor is locally recurrent, invasive and may occasionally metastasize. It thus appears that evaluation of the differential point of the two tumor groups by radiologic study is very important. We retrospectively compared sonographic find;.ngs of 6 cases of phylloides tumor with those of 4 cases of fibroadenoma, which proved pathologically in Ye mgnam University Hospital from 1984 to 1986. The mean age of the patients were 31.8 years old(from 14 to 41 years old) in phylloides tumor and 28.8 years old (from 17 to 40 years old) in giant fibroadenoma, respectively. The viewpoints of this analysis were size, shape and contour of the masses, internal echo pattern, posterior enhancement, and especially the existence of peripheral cyst or septal band echo. We found that diffenentiation of these two tumors by sonography was difficult. But peripheral cyst was found only in phylloides tumor and septal band echo was found largely in giant fibroadenoma. Although the existence of peripheral cyst or septal band echo in the breast mass was not pathognomonic findings, we suggest that the existence of septal band echo is preferential finding to fibroadenoma, and peripheral cyst is preferential finding to phylloides tumor.

The effects of insulin and exercise on glucose uptake of skeletal muscle were investigated in soleus muscle isolated from low dose streptozotocin induced diabetic rat in vitro. Glucose uptake was assessed by measuring ³H-methylglucose uptake in vitro. Basal glucose uptake in diabetes was reduced by approximately one-third of the control value (5.6±0.73µMol/g/20min. in diabetes versus 8.4±0.77 in control, P<0.01). There was also a significant decrease (P<0.01) in glucose uptake of diabetes at physiologic insulin concentration (200 µIU/ml) by 40% (6.1±1.20 versus 10.0±0.81). Furthermore, maximal insulin (20000 µIU/ml)-stimulated glucose uptake was 36% lower in diabetes as compared with control (7.3±1.29 versus 11.4±1.29, P<0.01). In contrast, exercise (1.0 km/hr, treadmill running for 45 min.) effect on glucose uptake was so dramatic in diabetes that glucose uptake at basal state was 8.+1.09 and insulin stimulated-glucose uptake were 10.2±1.47 and 11.9±1.64, in 200 and 20000 µIU/ml added insulin, respectively. These results suggest that insulin insensitivity develops in skeletal muscle after 2 weeks of streptozotocin-induced diabetes, but these insensitivity was recovered significantly by single session of running exercise.
