Anatomic changes in the retina occur even in young children with high myopia. Macular thickness characteristics of highly myopic children may influence the interpretation of data obtained with OCT.
Background/aim: To compare the central corneal thickness (CCT) of type II diabetes mellitus patients with age-and sex-matched healthy subjects and to determine the association of the severity of diabetic retinopathy and CCT.
Materials and methods:Type II diabetes mellitus patients without retinopathy, with nonproliferative retinopathy, and with proliferative retinopathy were organized as the three subgroups of the study group, and an age-and sex-matched control group was formed. All subjects underwent full ophthalmological examination and CCT measurement with ultrasonographic pachymetry. CCT values were compared between diabetic and healthy subjects and between the three diabetic subgroups. Correlation analysis was performed to determine any relationship between CCT and intraocular pressure.
Results:The average CCT was significantly higher in diabetic patients than in the control group (P = 0.04). CCT in diabetic patients without retinopathy did not significantly differ from that of patients with retinopathy (P = 0.64). Similarly, there was no significant difference in CCT between nonproliferative and proliferative diabetic retinopathy patients (P = 0.47). In the whole study population, CCT was significantly correlated with intraocular pressure (P < 0.01).
Conclusion:CCT is significantly increased in type II diabetes mellitus patients with respect to controls. Retinal disease severity does not seem to have an effect on corneal thickness.
Serous retinal detachment and optic disc swelling are unusual ocular manifestations of ALL. They may occur due to leukemic infiltration of ocular structures and may indicate extramedullary recurrence of the disease. Early recognition and treatment is crucial to improve prognosis.
The purpose of this study was to evaluate the early visual and refractive outcomes of a new aspheric monofocal microincision intraocular lens (IOL). This retrospective case series included eyes of patients who underwent implantation of a microincision IOL following 1.8 mm manual coaxial microincision cataract surgery and who attended regular postoperative follow-up visits on the first week and first, third, and sixth months. The postoperative uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction and predictability, intraoperative and postoperative complications, posterior capsule opacification (PCO), IOL centration, and surgically induced astigmatism (SIA) were evaluated. Sixty-three eyes of 38 patients ranging in age from 51 to 86 were included in the study. The mean preoperative BCVA was 0.52 ± 0.42 logMAR. At the postoperative sixth month, the mean postoperative UCVA and BCVA were 0.12 ± 0.11 and 0.01 ± 0.03 logMAR, respectively. The mean postoperative spherical equivalent refraction (SER) was -0.30 ± 0.49 D. The SER was within ± 1.00 D of the attempted correction in 95.2 % of the eyes. The mean SIA measured with vector analysis was 0.45 ± 0.28 D. Mild PCO was observed in 9 eyes (14.7 %) with none requiring Nd:Yag laser capsulotomy. On centration analysis, the IOL was found to be 0.26 mm on average to the supero-nasal position. The aspheric microincision IOL was safely implanted and provided satisfactory visual and refractive outcomes in the early postoperative period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
