The Imaging Characteristics of Lens Subluxation on the Ultrasound Biomicroscopy.

Background: To evaluate the imaging characteristics of the lens subluxation with the use of ultrasound biomicroscopy. Methods: From October 2018 to September 2019, 55 eyes diagnosed with lens subluxation were enrolled in the group. All patients underwent detailed eye examination and panoramic ultrasound biomicroscopy. Results: The most common sites of lens suspensory ligament injury were superior temporal side (32.73%) and superior nasal side (23.63%). The most common range of subluxation in all patients was 30°. Comparing the measurement indicators of all patients, ciliary body thickness (CBT) in affected eyes was smaller than that in healthy eyes (0.79 ± 0.21, 1.04 ± 0.16), the distance between ciliary process and crystal equator increased (1.91 ± 0.70, 1.17 ± 0.32), and iris-ciliary processes distance (ICPD) increased (1.04 ± 0.51, 0.80 ± 0.17) (P < 0.05). The range of subluxation in patients with lens subluxation was positively correlated with the distance between ciliary processes and the crystal equator. Conclusions: The ultrasound biological microscope has a good application significance in the diagnosis of lens subluxation. From this study, we suggest that the three indexes of CBT, ICPD, and the distance between the ciliary process and crystal equator are of high reference value in ultrasound biomicroscopy among patients with lens subluxation.

Point of care ultrasound and ocular injuries: A case of lens dislocation and a comprehensive review of the literature.

Point-of-care ultrasound (POCUS) can help the clinician diagnose different ocular pathologies including retinal detachment, vitreous detachment, lens dislocation, and intraocular foreign bodies. Ocular pathologies such as blurry vision, double vision, loss of vision, and eye trauma are common chief complaints and require a comprehensive evaluation in order to determine the etiology and choose the correct treatment. Specifically ultrasound can help the clinician decide whether an urgent ophthalmology consult is appropriate. We present a case in which a lens dislocation was diagnosed using POCUS and review the available literature.

Acute ocular traumatic imaging: what the radiologist should know [corrected].

Acute ocular trauma accounts for a substantial number of emergency department visits in the USA, and represents a significant source of disability to patients; however, the orbits remain a potential blind spot for radiologists. The goal of this article is to review the relevant anatomy of the orbit and imaging findings associated with commonly encountered acute ocular traumatic pathology, while highlighting the salient information which should be reported to the ordering clinician. Topics discussed include trauma to the anterior and posterior chamber, lens dislocations, intraocular foreign bodies, and open and contained globe injuries.

Facial Trauma: Delayed Development of a Subluxated Traumatic Cataract as Visualized on a Panoramic Image.

The immediate and long-term consequences of blunt orbital trauma leading to a subluxated lens and its subsequent calcification and opacification are reviewed. The accompanying panoramic image documents the process.

A rare case of traumatic posterior phacocele with retinal detachment.

Dislocation of crystalline lens into the anterior subconjunctival or subtenon's space is a rare but known complication of blunt trauma. Dislocation into the posterior subtenon's space is even rarer and can be associated with a complication such as occult scleral tear and retinal detachment. We report a case of traumatic posterior subtenon's dislocation of crystalline lens after blunt trauma and its successful surgical management.

[Late onset lens particle glaucoma in Marfan syndrome]. / Glaucoma tardío por partículas de cristalino en síndrome de Marfan.

CASE REPORT: A case is presented of an acute onset lens particle glaucoma originating from a crystalline lens spontaneously dislocated into the vitreous for more than 20 years in a patient diagnosed with Marfan syndrome. DISCUSSION: Marfan syndrome is a connective tissue disorder with autosomal dominant inheritance caused by fibrillin gene mutation. Ectopia lentis is the predominant ocular abnormality and a major diagnostic criterion. An association between Marfan syndrome and glaucoma has also been demonstrated. The reported case is unusual in that a complete spontaneous lens dislocation to vitreous was present and progressed to secondary lens particle open angle glaucoma.

Injuries of the globe: what can the radiologist offer?

Traumatic ocular injuries are a significant cause of blindness and visual deficits. In the setting of acute orbital trauma, urgent ophthalmologic evaluation and intervention are critical in preserving vision. However, in the acute trauma setting, clinical evaluation of the globe may be difficult in the presence of surrounding periorbital soft-tissue swelling and other associated injuries, and patient cooperation may be limited because of unresponsiveness, altered mentation, or sedation. Often, rapid access to imaging is part of the initial diagnostic evaluation, and radiologists may be the first to identify traumatic injuries of the globe. Because of this, radiologists should be familiar with normal orbital and globe anatomy at various imaging modalities and have a thorough understanding of the various patterns of ocular injury and their imaging appearances. Radiologists should also be familiar with the various mimics of ocular injury, including congenital and acquired conditions that may alter the shape of the globe, various types of ocular calcifications, and the different types of material used to treat retinal detachment. Such knowledge may help radiologists make accurate diagnoses, which facilitates prompt and appropriate patient care.

Spontaneous posterior capsular rupture with lens dislocation in pseudoexfoliation syndrome.

Spontaneous posterior capsule rupture is a very rare entity and its association with lens-nucleus dislocation even more. Herein we report such a case of spontaneous posterior capsule rupture with lens dislocation in a case of Pseudoexfoliation Syndrome.

Bedside ultrasound diagnosis of vitreous hemorrhage and traumatic lens dislocation.

We report a case where an emergency physician using bedside ocular ultrasound was able to diagnose vitreous hemorrhage and lens dislocation in an elderly patient. Bedside ultrasound performed by a physician trained in this imaging modality can diagnose ocular emergencies, facilitating appropriate consultation and treatment.
