PURPOSE: To report a case of bleb dysesthesia successfully treated after Baerveldt tube implantation. CASE SUMMARY: A 37-year-old woman presented with a history of persistent foreign body sensation and pain in the left eye. The patient was referred to our hospital and was diagnosed as having had plateau iris syndrome. Having shown no improvement with conservative management, she eventually received trabeculectomy in the left eye six months prior to her current presentation. Under the impression of bleb dysesthesia, she received artificial tears and a bandage contact lens. These, however, failed to alleviate her symptoms. She then had a compression suture of the bleb and bleb revision. These were performed sequentially but neither was effective. Finally, a Baerveldt tube implantation was performed successfully, and, three months later, bleb revision was performed using a donor sclera, which resulted in no further complaint of ocular discomfort. CONCLUSIONS: Bleb dysesthesia, although not a common postoperative complication, can occur after trabeculectomy and can be successfully treated with Baerveldt tube implantation. Patients should receive appropriate counseling and advice on bleb dysesthesia prior to undergoing trabeculectomy.

OBJECTIVES

Pre-impaired glucose tolerance (pre-IGT) is a prediabetes stage characterized by normoglycemia and compensatory hyperinsulinemia due to insulin resistance. Hyperinsulinemia increases cardiovascular disease (CVD) risk, especially, endothelial dysfunction (ED). However, there is paucity of studies on ED with hyperinsulinemia alone, particularly in individuals with pre-IGT. This study aimed to determine the presence of ED using brachial artery flow-mediated dilatation (FMD) among adult participants with pre-IGT and its correlation with insulin levels and other related clinical parameters.

METHODOLOGY

This is a cross-sectional analytical study. We screened adult patients with risk factors for developing diabetes (first-degree relative with type 2 diabetes mellitus, obesity, history of gestational diabetes and polycystic ovary syndrome). Brachial artery FMD was performed among participants with pre-IGT and findings were correlated with CVD risk factors using Pearson’s correlation and linear regression.

RESULTS

Of the 23 pre-IGT patients, 5 (21.74%) had decreased FMD values with significant associations with serum insulin and HbA1c. It was further observed that for every 1-unit increase in second-hour serum insulin and in HbA1c, there was a decrease in FMD values by 0.38% and 0.50%, respectively. Serum insulin was elevated, while other biochemical parameters were normal. Moreover, participants with low FMD were older, with higher BMI and had higher HBA1c, total cholesterol and low-density lipoprotein (LDL) cholesterol.

CONCLUSION

As early as the pre-IGT stage, endothelial dysfunction using the FMD test is already present, with red flags on other CVD risk factors already developing.
