Corneal ectasia following LASIK

Saudi Journal of Ophthalmology, 2011
The cornea is a perplexing and enigmatic ocular structure. Its invigorating functions consist of conflicting demands. The cornea has to protect the eye, contain the intraocular pressure, and provide a smooth optical surface. These functions can be affected by a variety of diseases including immunologic, infectious, metabolic, genetic, and traumatic ...

Biomechanics of corneal ectasia and biomechanical treatments [PDF]

Journal of Cataract and Refractive Surgery, 2014
Many algorithms exist for the topographic/tomographic detection of corneas at risk for post-refractive surgery ectasia. It is proposed that the reason for the difficulty in finding a universal screening tool based on corneal morphologic features is that curvature, elevation, and pachymetric changes are all secondary signs of keratoconus and post ...

Corneal ectasia associated with postoperative hypotony [PDF]

Canadian Journal of Ophthalmology, 2019
Importance Although post-operative hypotony is common, many ophthalmologists argue that ocular hypotony is relatively inconsequential and question its occurrence as a surgical complication. Corneal changes related to ocular hypotony has seldom been described.

Stromal Curvature, Power and Corneal‐Stromal Curvature Ratios From a Hybrid AS‐OCT in Eyes With Keratoconus

Clinical &Experimental Ophthalmology, Volume 54, Issue 1, Page 9-20, January/February 2026.
ABSTRACT Background To characterise stromal curvature and curvature ratios in keratoconus (KCN) using anterior segment OCT, and to evaluate the implications of using single‐, two‐, and three‐surface refractive models for corneal power estimation in ectatic eyes. Methods Retrospective observational study.

Ocular and Systemic Phenotyping of Bardet–Biedel Syndrome Type 7 (BBS7) in a Palestinian Male: Case Report and Literature Review

Case Reports in Ophthalmological Medicine, Volume 2026, Issue 1, 2026.
Introduction Bardet–Biedl syndrome (BBS) is a rare autosomal recessive ciliopathy with at least 26 identified causative genes. BBS7 accounts for approximately 1.5% of cases. The syndrome is characterized by retinal degeneration, obesity, polydactyly, intellectual disability, and renal anomalies.

Ectasias corneales

, 2020
Primary non-inflammatory ectatic corneal changes are all conditions that are accompanied by increased curvature and decreased corneal thickness, leading to progressive corneal protrusion. A Medline review of the latest information available on this topic, including its updated diagnosis and management, was carried out.

A Novel Mutation of the FBN1 Gene in a Chinese Family With Marfan Syndrome and Unanticipated Discoveries of Family Members

Genetics Research , Volume 2026, Issue 1, 2026.
Marfan syndrome (MFS) is an autosomal dominant connective tissue disorder caused by pathogenic variants in the FBN1 gene. Using whole‐exome sequencing (WES) in a Chinese MFS family, we identified a novel heterozygous nonsense variant FBN1:c.1415dup;p.(Tyr472Ter), which cosegregates with the disease phenotype and results in protein truncation ...
