OBJECTIVE: To assess prevalence of aortic involvement in relapsing polychondritis (RP) patients; to evaluate clinical features and long-term outcome of RP patients exhibiting aortitis, aortic ectasia and/or aneurysm. METHODS: 172 RP patients underwent aortic computed tomography (CT)-scan; they were seen in 3 medical centers. RESULTS: 11 patients (6.4%) had aortic involvement, occurring within a median time of 2 years after RP diagnosis. CT-scan showed isolated aortitis (n=2); the 9 other patients exhibited: aortitis and aortic aneurysm (n=2) or ectasia (n=1), isolated aortic aneurysm (n=4) or ectasia (n=2); aortic localizations were as follows: thoracic (n=6), abdominal (n=2), thoracic and abdominal (n=4) aorta...

BACKGROUND: Several recent reports have implicated vascular ectasia and vessel contact with dysfunction of the visual apparatus. A subset of patients with pre-chiasmatic visual deterioration have an ectatic internal carotid artery (ICA) that displaces and flattens the optic nerve (ON) rostrally as the ON exits the skull base. We will offer a proposed pathophysiological mechanism and describe a straightforward surgical technique for dealing with this interesting problem. METHODS: Via an ipsilateral pterional craniotomy, the bony roof of the optic canal is removed...

Coarctation of aorta is a rare congenital malformation and is usually accompanied by other cardiac or vascular lesions. In this case we describe a 51-year-old patient presented with coarctation of the aortic arch and postcoarctation ectasia concomitant with a left subclavian artery aneurysm. Endovascular therapy included the deployment of an inverted wedge-shaped covered stent inserted by a long "chimney" stent and another cylinder-covered stent, forming a "sandwich"-like configuration. The symptoms were alleviated after surgery, and no perioperative or stent-graft-related complications were observed at a 2-year follow-up...

BACKGROUND: Corneal graft (CG) surgery is the most common and successful tissue transplant worldwide. A small and important group of patients are operated in emergency situations, typically to save a perforated eye. Our knowledge of the indications and outcomes of emergency corneal graft (eCG) is limited. METHODS: Retrospective, multifactorial analysis of all CGs registered by the UK Transplant Service from April 1999 to March 2005. RESULTS: A total of 12 976 CGs were performed...

Keratoconus is a relatively common (1 : 2000) bilateral disease leading to a change in biochemical and biomechanical corneal structure as well as thinning and ectasia. For more than 10 years, crosslinking has been a therapeutic option in cases of progression. Using riboflavin and UVA-radiation, the anterior corneal stroma (300 µm) gets stiffened by crosslinking of collagen fibers. When protocols and limitations are adhered, the procedure is described to be effective and of low-risk. This review gives an overview about physiologic and pathologic changes in keratoconic corneas before and after crosslinking...

AIM: Corneal keratectasia is one of the complications associated with laser in situ keratomileusis (LASIK) that results in vision impairment. The pathogenesis of post-LASIK ectasia (PLE) remains underexplored. We report the tear cytokine profile and in vivo confocal microscopy (IVCM) findings in eyes with PLE. METHODS: This retrospective study included age-matched 7 (14 eyes) post-LASIK controls (PLCs) and 6 (12 eyes) PLE subjects. Corneal topography was used to categorise the subjects into PLC and PLE groups...

REVIEW
Virgilio Galvis, Alejandro Tello, Alvaro I Ortiz, Luis C Escaf
Corneal cross-linking (CXL) is an option that in the last decade has demonstrated its efficacy and safety in halting the progression of keratoconus (KCN) and other corneal ectasias. Its indication has been extended beyond the classic definition that required evidence of KCN progression, especially in the presence of some risk factors for a possible progression (particularly the younger age). However, the results can be still somewhat variable today. There are several protocols, each with its own advantages and disadvantages...

Keratoconus (KC) is a progressive corneal ectasia linked to thinning of the central cornea. Hard contact lenses, rigid gas permeable lenses, and scleral lenses are the primary treatment modalities for early to mid- stages of KC to correct refractive error and astigmatism that develops as a result of an irregular corneal structure. These treatments are associated with significant drawbacks, including reduced availability of the tear film and oxygen to the corneal epithelium and stroma. However, it remains unknown whether hypoxia affects corneal integrity in the KC pathobiology...

We describe the case of a keratoconus patient with pigment dispersion syndrome (PDS) who was treated for progressive corneal ectasia with corneal collagen crosslinking (CXL). Pigment dispersion syndrome has been shown to have associated morphologic changes of the corneal endothelium. Corneal CXL has the potential to cause toxicity to the corneal endothelium, and adjacent pigment might increase the likelihood of damage. In this case, the presence of PDS had no detrimental effect on the outcome of treatment, and no complications were observed at 12 months follow-up, indicating that it may be safe to perform corneal CXL in the setting of PDS...

PURPOSE OF REVIEW: Refractive surgery has stimulated considerable progress in corneal and anterior segment imaging, and optical characterization of the eye. From front surface corneal topography, we evolved to three-dimensional corneal tomography with limbus to limbus characterization of the front and back corneal surfaces and pachymetric mapping. Corneal anatomical evaluation has further evolved to layered or segmental tomography with the ability to characterize corneal epithelial thickness profile and the elevation of stromal front surface...

BACKGROUND AND OBJECTIVES: Vitamin D is generally known to be closely related to inflammation. The effects of vitamin D on coronary artery disease (CAD) are not fully explained. Nowadays, coronary artery ectasia (CAE) cases are common and are regarded as being a kind of CAD. We aimed to investigate, in a case-control study, the relationship between vitamin D and CAE without an associated inflammatory process. SUBJECTS AND METHODS: This study population included 201 patients (CAE group, 121 males; mean age, 61...

Gastric antral vascular ectasia (GAVE) and chronic radiation proctitis (CRP) are well-known causes of repeated gastrointestinal bleeding and iron deficiency anemia. Argon plasma coagulation (APC) is the most common endoscopic therapy used, but some patients need multiple APC sessions. Radiofrequency ablation (RFA) is recently used in GAVE and CRP treatment with promising results. In this case series, we analyzed data for 15 patients with GAVE and 5 patients with CRP that had multiple prior APC treatment. They were treated with RFA HALO 90 catheter (HALO90 Ablation Catheter System; Covidien, GI Solutions, Sunnyvale, CA) in our tertiary referral center...
