Diabetes mellitus (DM) is an important health problem that induces microvascular complications such as retinopathy, nephropathy, and neuropathy. Ocular complications associated with type 2 DM are progressive and rapidly becoming the world’s most significant cause of morbidity and preventable with early detection and timely treatment. A prospective, analytical observational with cross-sectional study aimed to analyse of glycaemic control and low-density lipoprotein cholesterol (LDL-C) with glaucomatous optic neuropathy as a microvascular complication in patients with type 2 DM, was conducted in Universitas Sumatera Utara Hospital and Satellite Hospital, Medan, Indonesia, from April 2020 to August 2020. The study included 66 participants with type 2 DM. The patients were investigated for haemoglobin A1c (HbA1c) level, LDL-C level, and ophthalmology examination including visual acuity (VA), intraocular pressure (IOP) measurement by Goldmann Applanation Tonometer, retinal nerve fiber layer (RNFL) thickness with spectral domain Optovue optical coherence tomography, and visual field defect with Octopus Perimeter. This study showed a significant correlation between HbA1c with VA (p = 0.030), IOP (p = 0.035), RNFL thickness (p = 0.002), visual field defect (p = 0.032), and duration of DM (p = 0.003) and showed significant correlation between LDL-C with VA (p = 0.048), IOP (p = 0.006), and duration of DM (p = 0.042).This study concluded that higher HbA1c and LDL-C was correlated with Glaucomatous Optic Neuropathy as a microvascular complication in type 2 DM. Collaboration between endocrine and ophthalmology department was strongly advised
