Relationship Of High Density Lipoprotein Cholesterol (HDL-C) Levels On The Thickness Of The Ganglion Cell Complex (GCC) In Primary Open Angle Glaucoma (POAG) With A History Of Type 2 Diabetes Mellitus
The Relationship Between High Density Lipoprotein Cholesterol (HDL-C) Levels and Ganglion Cell Complex (GCC) Thickness in Primary Open Angle Glaucoma (POAG) Patients with a History of Type 2 Diabetes Mellitus
Introduction
Diabetes mellitus is a significant risk factor for glaucoma, a group of eye conditions that damage the optic nerve, leading to vision loss and even blindness. The relationship between diabetes and glaucoma can be explained by changes in biochemical pathways, increased oxidative stress associated with lipid metabolism, and disorders of the bloodstream due to interrupted endothelial autoregulation of blood vessels. The Ganglion Cell Complex (GCC), which consists of the Inner Plexiform Layer (IPL), Retinal Ganglion Cells (RGC), and Retinal Nerve Fiber Layer (RNFL), is one of the structures affected in this condition. High Density Lipoprotein (HDL) is a type of lipoprotein that functions as an antioxidant, anti-anogeneic, and provides a protection effect on the endothelium. This study aims to determine the relationship between HDL-C levels and GCC thickness in POAG patients who also have a history of type 2 diabetes mellitus.
Background
Diabetes mellitus is a chronic metabolic disorder characterized by high blood sugar levels, which can lead to various complications, including cardiovascular disease, kidney disease, and eye disease. Glaucoma is a group of eye conditions that damage the optic nerve, leading to vision loss and even blindness. The relationship between diabetes and glaucoma is complex and multifactorial, involving changes in biochemical pathways, increased oxidative stress associated with lipid metabolism, and disorders of the bloodstream due to interrupted endothelial autoregulation of blood vessels.
Research Purposes
This study aims to determine the relationship between HDL-C levels and GCC thickness in POAG patients who also have a history of type 2 diabetes mellitus. The study will investigate whether there is a significant difference in HDL-C levels between POAG patients with and without diabetes, and whether there is a correlation between HDL-C levels and GCC thickness in POAG patients with diabetes.
Research Methods
In this study, analytical observational methods are used by cross-sectional data collection. A total of 65 research subjects consisted of 33 POAG patients with a history of type 2 diabetes mellitus and 32 POAG patients without diabetes. The study was conducted at the Polyclinic of the University of North Sumatra Hospital and other Networking Hospitals from October 2020 to January 2021.
Research Results
Most research subjects come from women's groups with an age range of 46-65 years. The average HDL-C content in POAG groups with type 2 diabetes is recorded at 48.24 mg/dl (SD = 11.53 mg/dl), while the POAG group without diabetes is 44.59 mg/dl (SD = 8.30 mg/dl). The chi-square test results show a significant difference in the perimetric value of the mean deviation (MD) and the pattern of standard deviation (PSD) between the two groups (p <0.05). However, GCC thickness examination does not show a significant difference between POAG groups and diabetes and without diabetes (P> 0.05).
Conclusion
This study found that thinning of GCC thickness, both at the average GCC, Superior GCC, and GCC inferior in POAG patients with type 2 diabetes mellitus compared to POAG patients without diabetes. Nevertheless, this difference does not reach the expected level of significance. This finding provides important insights for clinical treatment of POAG, especially for patients who also suffer from type 2 diabetes mellitus, indicate that although HDL-C levels appear to be not significantly related to the thickness of GCC, there is a certain impact of the condition of diabetes on the thickness of the retinal structure.
Implications
The results of this study encourage the need for further attention to the relationship between lipid metabolism, HDL-C levels, and structural changes that occur in GCC in POAG patients with diabetes. A better understanding of this relationship is expected to improve the prevention and treatment strategy to reduce the risk of further damage to patients with this condition.
Limitations
This study has several limitations. Firstly, the sample size is relatively small, which may limit the generalizability of the findings. Secondly, the study only investigates the relationship between HDL-C levels and GCC thickness in POAG patients with diabetes, and does not explore other potential risk factors for glaucoma. Finally, the study only examines the relationship between HDL-C levels and GCC thickness, and does not investigate other potential biomarkers for glaucoma.
Future Directions
Future studies should aim to investigate the relationship between lipid metabolism, HDL-C levels, and structural changes that occur in GCC in POAG patients with diabetes. Additionally, studies should explore other potential risk factors for glaucoma, such as hypertension, smoking, and family history of glaucoma. Furthermore, studies should investigate the effectiveness of different treatment strategies for glaucoma, including medication, laser therapy, and surgery.
Conclusion
In conclusion, this study found that thinning of GCC thickness, both at the average GCC, Superior GCC, and GCC inferior in POAG patients with type 2 diabetes mellitus compared to POAG patients without diabetes. Although the difference does not reach the expected level of significance, this finding provides important insights for clinical treatment of POAG, especially for patients who also suffer from type 2 diabetes mellitus. The results of this study encourage the need for further attention to the relationship between lipid metabolism, HDL-C levels, and structural changes that occur in GCC in POAG patients with diabetes.
Q&A: Relationship Between High Density Lipoprotein Cholesterol (HDL-C) Levels and Ganglion Cell Complex (GCC) Thickness in Primary Open Angle Glaucoma (POAG) Patients with a History of Type 2 Diabetes Mellitus
Q: What is the relationship between diabetes and glaucoma?
A: Diabetes mellitus is a significant risk factor for glaucoma, a group of eye conditions that damage the optic nerve, leading to vision loss and even blindness. The relationship between diabetes and glaucoma can be explained by changes in biochemical pathways, increased oxidative stress associated with lipid metabolism, and disorders of the bloodstream due to interrupted endothelial autoregulation of blood vessels.
Q: What is the role of High Density Lipoprotein (HDL) in the body?
A: HDL is a type of lipoprotein that functions as an antioxidant, anti-anogeneic, and provides a protection effect on the endothelium. HDL helps to remove excess cholesterol from the bloodstream and transport it to the liver for excretion.
Q: What is the Ganglion Cell Complex (GCC) and why is it important?
A: The GCC is a group of cells in the retina that are responsible for transmitting visual information from the eye to the brain. The GCC consists of the Inner Plexiform Layer (IPL), Retinal Ganglion Cells (RGC), and Retinal Nerve Fiber Layer (RNFL). The GCC is important because it is a key structure in the visual pathway, and damage to the GCC can lead to vision loss and even blindness.
