Title

Evaluation of ocular comorbidities among cataract surgery through medical imaging method

English Abstract

ntroduction and Objective: Imaging plays an indispensable role in clinical care in ophthalmology, ranging from diagnostics to risk stratification and treatment monitoring. Imaging biomarkers were identified in many diseases such as diabetic retinopathy, age-related macular degeneration and glaucoma. Cataract is the most common cause of blindness in the world and it is estimated that about one hundred thousand cases of cataract surgery are performed in Iran annually. One of the factors affecting cataract is ocular comorbidities. Due to the rarity of studies in this field, this study aimed to evaluate the ocular complications of comorbidities in patients undergoing cataract surgery at Noor Surgery Centre in Ardabil, Iran. Materials and Methods: This descriptive cross-sectional study was performed on 780 patients referred to Noor Ophthalmology Clinic in Ardabil city with cataract diagnosis. Data were collected by a researcher using a checklist. Data analysis was performed by SPSS 25 software using descriptive statistics. Results: Of the 1018 eyes studied, 590 (58%) were female and 428 (42%) were male. Mean age of patients was 65.88 ± 11.43 years. The mean intensities of PSC, Nuclear, and cortical cataracts were 4.56 ± 0.62, 4.79 ± 0.89, and 4.21 ± 0.48, respectively. Our findings revealed a significant association of cataract type in diabetic patients with normal retina (p=0.034), pseudoexfoliation syndrome (p=0.001), hyperopia (p=0.008), corneal opacity (p=0.036) and nasolacrimal duct obstruction (p=0.032) in compare with other patients. There was no significant difference in other comorbidities in terms of cataract types. Conclusions: Since age, sex and comorbidity factors can affect cataract, periodic medical examinations and training in healthy lifestyle can be an effective step in preventing or decreasing cataracts formation, as well as improvement of prognosis of cataract surgery through OCT angiography.
