Traumatic eyeball damages is a topical issue in present-day ophthalmology as they constitute one of the main causes vision loss people working age. Purpose: to assess feasibilty, effectiveness and safety one-time early-stage microinvasive optical reconstructive surgery patient with traumatic damage consequences: swelling cataract, lens ligamentous apparatus defect, iridodialysis, mydriasis. Mat...
fibrillin-rich microfibrils are susceptible to degradation by serine proteases, and the amino acid substitutions found in Marfan syndrome change the fragmentation patterns. Fibrillin degradation products generated by MMP activity provide conclusive evidence that these enzymes cause specific changes to assembled microfibrils. In Marfan syndrome, most of the mutations in fibrillin-1 are found wit...
Anterior megalophthalmos is characterized by megalocornea associated with a very broad anterior chamber and ciliary ring elongation. It is also called X-linked megalocornea. It is accompanied by early development of cataracts, zonular anomalies, and, rarely, vitreoretinal disorders. Subluxation of a cataract can occur in cataract surgery because of zonular weakness. In addition, in most patient...
A four-year-old, male German Shepherd dog with severe pain in the left eye following a corneal perforation with a foreign body was examined. An ophthalmic examination revealed conjunctival hyperaemia and pancorneal dense oedema, preventing a diagnosis of deeper structures of the eye and lowered IOP. Vision testing was missing or impossible to detect. Ultrasonography showed a solid hyperechoic l...

PURPOSE The authors present a patient with Marfan syndrome who underwent cataract surgery using a novel device for fixation of capsular bag. METHODS The capsule fixation device (CFD) is poly(methyl methacrylate) arch with double-armed bent hook that can be introduced into the anterior chamber through the clear corneal incision, placed with a rest on the capsule equator, and sutured to the scl...
