“…The obtained results confirmed the observation of Atas et al [3], who, on a group of 54 women of Turkish nationality, showed the increase in CCT in the third trimester in comparison to a study carried out after childbirth (p < 0.001). Our results, however, stand in opposition to the study of Sen et al [6], Goldich et al [5] and Naderan et al [4] who, according to the systematic review by Taradaj et al [1], did not show such the dependence. The precise mechanism that can explain the rise in CCT during pregnancy has not been described so far.…”

“…Therefore, it is necessary to establish if pregnancy modifies the anatomical structure of the cornea and the an-terior chamber of the eye. Inspired by the systematic review [1], which has recently appeared in the journal, we would like to present the results of our own research in which we assessed the impact of an uncomplicated pregnancy and a natural delivery on the changes in the anatomy of the anterior segment of the eye.…”

Objectives:The main goal of the study was to determine whether uncomplicated pregnancy and natural labor exert influence on the cornea and the anterior chamber of the eye. Material and methods:The study included 114 eyes of 57 women in age of 21-35 years old. Only patients in the physiological pregnancy and giving natural birth were recruited into study.Prospective observative examination was performed. Patients were diagnosed twice: in 36 HBD and 6 weeks after labor. Using the Scheimpflug camera (Pentacam system) the following parameters were assessed: central corneal thickness (CCT), keratometric parameters: flat (K1) and steep (K2), astigmatism value and axis, anterior chamber depth (ACD), anterior chamber volume (ACV) and anterior chamber angle (ACA). The statistical analysis was carried out in the StatSoft Statistica 13 program.Results: CCT value is greater in the third trimester than in 6th week after the labour. ACD and ACA values are higher in 36 HBD than in the post-partum period but the difference is not statistically important (p > 0.05). K1, K2, cylindrical refraction error, axis of cylindrical refraction error do not change. Conclusions:Authors claim that it is the result from an increase in water retention in the corneal stroma as a response to hormonal changes. The plasticity of the anterior chamber seen before delivery can be a natural adaptive mechanism of the female body, which counteracts the excessive increase in intraocular pressure in the second stage of delivery.

Introduction: Pregnancy causes an increase in central corneal thickness (CCT) and a reduction in intraocular pressure (IOP), especially in the third trimester. However, there is very limited published data regarding CCT and IOP in gestational diabetes mellitus (GDM) on diet control. This study is aimed to compare the means of CCT and IOP between pregnant women with GDM on diet control, healthy pregnant women, and healthy non-pregnant women. Methods: This is a comparative cross-sectional study. A total of 184 women were recruited and divided into the following three groups: 61 pregnant women with GDM on diet control, 63 healthy pregnant women, and 60 healthy non-pregnant women as control. All subjects have undergone ocular examination during their 36-40 weeks of gestation. CCT measurement was done using a specular microscope and IOP measurement using a non-contact tonometer. Data from the right eye were analyzed. Results: The mean age was 32 (4.0) years in GDM on diet control, 29 (3.0) years in healthy pregnant women, and 27 (5.4) years in healthy non-pregnant women. The number of gravidas was 2.5 (0.8) in women with GDM on diet control and 2.3 (0.8) in healthy pregnant women. There was a significant difference (p<0.05) in the mean CCT in women with GDM on diet control compared to healthy pregnant and healthy non-pregnant women. The mean IOP is significantly lower in both pregnant women with GDM on diet control and healthy pregnant groups, compared to the healthy non-pregnant women group. Conclusion: Women with GDM showed significantly thicker mean CCT than healthy pregnant and non-pregnant women. The mean IOP is significantly lower in both pregnant women with GDM on diet control and healthy pregnant groups, compared to the healthy non-pregnant women group.

“…As long as the structure and function of the anterior chamber angle are normal, the anterior chamber hemorrhage can often be absorbed quickly in a short time. (2) Fibrinolytic enzyme action: this enzyme decomposes the blood cake to form a free state and is discharged out of the anterior chamber together with body fluids after dissolution [ 18 ]. (3) Phagocytosis: the food cells in the front water chamber act on the red blood cells to promote the eyes to come out from the corners of the eyes [ 19 ].…”

The front part of the eye is exposed to the surface of the body, making it susceptible to injury. Blunt eye injuries often destroy the tissue structure in the anterior part of the eye. Often there is detachment of the iris root, separation of the ciliary body, the angle of retraction of the chamber, and complete dislocation or subluxation of the lens. Ordinary ocular ultrasound can penetrate into opaque tissue, but because of its low resolution, it can only show its outline, which is still very small for doctors in assisting diagnosis. Ultrasonic biomicroscopy is a very real-time analysis, will not be affected by the refraction space, and has great application value for ocular trauma. Based on this, this article proposes the ultrasound biomicroscope diagnosis analysis and fine nursing research of traumatic anterior chamber injury based on intelligent virtual reality technology. This article describes literature methods, experimental analysis methods, and other methods, in-depth study of the causes of traumatic anterior injuries, ultrasound biomicroscopy, and other theoretical knowledge, ultrasound biomicroscopy and microcontrol experiments for traumatic anterior injury design, and finally the causes of eye damage. This study compares the pairing results of ultrasound biomicroscopy biological measurements, analyzes the relationship between anterior bleeding level and anterior ocular injury, and analyzes the outcome and extent of service ophthalmology. The angle retreat accounted for 52.17% in grade I, 72.22% in grade II, and 60% in grade III. Anterior bleeding can cause single or complex iris root detachment, iris root detachment, ciliary body detachment, and angular leakage. The more the bleeding, the more serious the eye damage.
