Background Free-floating intraocular cysts may be found in the anterior chamber (FZV) and the vitreous (FZG). The first description of a cyst was 150 years ago, and they are considered to be ocular rarities. Materials and Methods The actual knowledge about FZV and FZG is shown on the basis of two exemplary patients. Results and Discussion Patient 1 had a FZV as an incidental finding which had a smooth surface, a slight pigmentation and was translucent. The ultrasound biomicroscopy revealed an echo-free interior space...

PURPOSE: To determine if the anterior choroid is involved in ocular change during the Valsalva manoeuvre (VM). MATERIALS AND METHODS: Fifty-three healthy volunteers aged 18-65 years with normal visual field test results and no history of intraocular pressure (IOP) exceeding 21 mm Hg were recruited. Anterior and posterior choroidal changes before and during VM were recorded by ultrasound microscope and swept-source optical coherence tomography, respectively. Parameters of the anterior segment included ciliary body thickness (CBT0), thickness of the choroid at a distance of 4 mm from the root of the iris (CT4), anterior placement of the ciliary body (APCB) and trabecular-ciliary angle (TCA)...

Despite being a posterior segment ocular surgery, pars plana vitrectomy (PPV) may also affect anterior segment parameters. We aimed to investigate anterior segment alterations following PPV using ultrasound biomicroscopy (UBM) to visualize the structural anatomy of the eye. In this study, we enrolled phakic patients undergoing PPV (as the sole procedure). The anterior chamber depth, crystalline lens anterior-posterior (AP) diameter, anterior chamber angle, ciliary body dimensions, and integrity of the ciliary zonules and posterior capsule were assessed using UBM before and at least 3 months after PPV...

We report a case of Norrie disease, diagnosed by prenatal ultrasound, confirmed by Sanger sequencing of the DNP gene from the aborted fetal cord blood and histologically. Prenatal ultrasound revealed no abnormality in either eye at 22(+1) and 31(+4) gestational weeks, but at 36(+5) gestational weeks both eyes had massive vitreous cavity opacities with complete retinal detachment. Norrie disease was initially suspected because of an older male sibling with the disease. To our knowledge, prenatal ultrasound diagnosis of Norrie disease has been previously described only one case in 1993 in a 34-week-old fetus...

Retinoblastoma and uveal melanoma are fast spreading eye tumors usually diagnosed by using 2D Fundus Image Photography (Fundus) and 2D Ultrasound (US). Diagnosis and treatment planning of such diseases often require additional complementary imaging to confirm the tumor extend via 3D Magnetic Resonance Imaging (MRI). In this context, having automatic segmentations to estimate the size and the distribution of the pathological tissue would be advantageous towards tumor characterization. Until now, the alternative has been the manual delineation of eye structures, a rather time consuming and error-prone task, to be conducted in multiple MRI sequences simultaneously...

INTRODUCTION: The combination of bilateral microphthalmos, cystic coloboma and eyelid agenesis is rare. The definite diagnosis of this malformation is established by fundoscopic examination and confirmed by imaging modalities such as ultrasonography (US) and magnetic resonance imaging (MRI). This disorder may be associated with specific chromosomal abnormalities. CASE REPORT: A 1-week-old male newborn was referred for bilateral eyelid agenesis. He was born at term by caesarean for foetal distress, after an uneventful gestation...
