Cataract in diabetic patients is a major cause of blindness in developed and developing countries. The pathogenesis of diabetic cataract development is still not fully understood. Recent basic research studies have emphasized the role of the polyol pathway in the initiation of the disease process. Population-based studies have greatly increased our knowledge concerning the association between diabetes and cataract formation and have defined risk factors for the development of cataract. Prevention of eye complications by removing metabolic risk factors and good control of the disease is the most efficient step, because no effective treatments in the absence of optimal glycemic control through diet and medication. Diabetic cataract is a condition that benefits from surgery with good functional recovery. This recovery depends on the detection and treatment of diabetic retinopathy with photocoagulation correct laser.

Purpose: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have risen exponentially in usage and have been shown to exert neuroprotective and anti-inflammatory effects across multiple organ systems. This study investigates whether GLP-1RAs influence the risk for age-related ocular diseases.
Design: Retrospective cohort study.
Mydriasis Stability During Cataract Surgery in Patients with Systemic Comorbidities Using a Standardised Combination of Intracameral Mydriatics and Anaesthetic.
Life (Basel)
January 2025
University Clinical Centre named after Prof. K. Gibiński, Medical University of Silesia, 40-514 Katowice, Poland.
Background: This study aimed to evaluate mydriasis stability during cataract surgery in patients with systemic comorbidities such as diabetes mellitus (DM) and pseudoexfoliation syndrome (PXF) after a standardised combination of intracameral mydriatics and anaesthetic (SCIMA). Stable mydriasis is crucial for safe and effective phacoemulsification.
Methods: Patients were included if they achieved pupil dilation ≥6.

Diabetes has become a global epidemic, contributing to significant health challenges due to its complications. Among these, diabetes can affect sight through various mechanisms, emphasizing the importance of early identification and management of vision-threatening conditions in diabetic patients. Changes in the crystalline lens caused by diabetes may lead to temporary and permanent visual impairment.

Background: To assess associations between mortality and major ocular parameters and diseases.
Methods: The population-based Ural Eye and Medical Study (UEMS) and Ural Very Old Study (UVOS) included 5899 individuals (age: 40+ years) and 1526 individuals (age: 85+ years), respectively. Cause-specific mortality was determined using the government regional information and analytical system.
New-onset Type 1 Diabetes Mellitus Presenting as Bilateral Cataracts in a 15-year-old Girl.

Cataracts secondary to type 1 or type 2 diabetes are not uncommon in adults; however, they are a rare finding in pediatric patients with type 1 diabetes. A 15-year-old girl presented with progressively worsened bilateral vision for 6 months. Her vision rapidly deteriorated over the previous month, prompting further evaluation that found bilateral cataracts with haziness in all layers and swollen lenses.
