Introduction: This study aimed to investigate the effect of phacoemulsification on macular thickness and volume in diabetic patients without retinopathy using optical coherence tomography (OCT).Methods: This prospective study included 37 diabetics and 55 non-diabetic patients (n=92) with cataract who were scheduled for phacoemulsification. The participants were entered into the study based on the inclusion and exclusion criteria following a complete eye examination. Macular thickness and volume were measured preoperatively as well as one month postoperatively using the OCT (Spectralis; Heidelberg Engineering, Heidelberg, Germany).Results: The present study analyzed 76 eyes of 76 patients with immature cataract. No significant differences were observed between diabetic and non-diabetic groups in terms of thickness and volume in the macular area. However, the results showed a significant increase in both groups regarding the thickness and volume after phacoemulsification. Conclusion: The results of the present study reveal that diabetes has no effects on the changes in macular thickness and volume after cataract surgery in diabetic eyes without retinopathy.

Introduction: This article aimed to review the literatures on visual impairments and ocular changes in premature infants with low birth weight and gestational age.Methods: Five electronic databases including: PubMed, Web of Science, Science direct, Ovid, and Scopus were searched. Original articles published until 2015 describing preterm infants were reviewed. Repetitive and derivative articles were excluded.Results: Out of 100 unique, potentially relevant articles, 42 studies that addressed and met the inclusion criteria were evaluated.Conclusion: Prematurity affects ocular structures (from anterior to posterior segment) and functions. Premature infants are at risk of myopization. Concerning the changes in premature infants, a significant increase is found in axial length, intraocular pressure, and central corneal thickness; moreover, high incidence of retinal changes is reported as a result of prematurity. On the other hand, visual acuity, tear, electroretinogram, and visual evoked potential responses decrease with prematurity. The most common ophthalmic disorders in preterm infants are myopia and retinopathy of prematurity, which could affect life quality due to reduced visual acuity.
