AIMS/PURPOSE To report the preoperative use of anterior segment optical coherence tomography (AS-OCT) for the determination of pre-existing posterior capsule defect in patients with posterior polar cataract. METHODS Three patients presented with posterior polar cataract and were evaluated preoperatively using AS-OCT, revealing in one patient intact posterior capsule and in the other two a pre...

Closed-globe traumatic cataract is not uncommon in males in the pediatric age group. However, there is a relative paucity of literature on isolated posterior lens capsule rupture associated with closed-globe traumatic cataract. We report a case of a 6-year-old boy who presented with white cataract 1 day after blunt trauma to the forehead associated with posterior capsular rupture that was detec...

BACKGROUND Capsular block syndrome is an uncommon complication that occurs after cataract surgery. It is characterized by capsular distension, anterior intraocular lens displacement, anterior chamber shallowing, and unexpected myopic shifts. We report a case of recurrent fibrotic capsular block syndrome with Elschnig's pearl-type posterior capsule opacification 10 months after neodymium-yttrium...

PURPOSE To study prospectively using optical coherence tomography whether topical latanoprost induces retinal disorders in patients that underwent cataract surgery. METHODS Randomized, masked-observer, one-month clinical trial. Pseudophakic patients were treated with latanoprost (n=10) or lubricant drop q.d. (control group) (n=10). Half of the patients of each group presented ruptured posteri...

Aim: To examine the histology of preserved anterior lens capsule in vitrectomised and lensectomised rabbit eyes with and without silicone oil tamponade. Methods: Forty adult Japanese albino rabbits received two port vitrectomy and lensectomy with or without silicone oil tamponade in one eye under both general and topical anaesthesia. Anterior lens capsule was preserved during operation. After h...

AIM To study the behaviour of residual lens epithelial cells after capsulorhexis and expression of material from the isolated lens. METHODS Human and bovine lens capsules were isolated, sterile non-toxic silicone rings inserted, and the preparations placed in organ culture for up to 12 weeks. Cell coverage of the posterior lens capsule was recorded and the capsules were examined, both pre- an...

Anatomy The canine lens is suspended in the eye by zonular ligaments which arise from the ciliary epithelium and attach to the lens at the equator. The lens capsule is an elastic basement membrane which encloses the underlying anterior epithelium and lens fibers. The size of the lens is approximately 7mm in the anterior/posterior aspect and 10mm as the equatorial diameter. The anterior lens cap...

Comments are made on the method of removing the anterior capsule during the performance of extracapsular cataract operations. The difficulty of performing this manoeuvre adequately is emphasised. Observations carried out during the postoperative period by means of the slit-lamp revealed some hitherto undescribed changes in the capsule. The edge of the anterior capsule can be clearly seen and lo...

CONTEXT The high number of repetitions and high forces associated with overhead throwing lead to anatomical adaptations, such as humeral retrotorsion and posterior-capsule thickness, in elite and professional baseball athletes. However, little is known about the origin and progression of these changes that may account for the increasing trend of chronic shoulder injuries in youth baseball and p...
