Your 101 guide to interpreting the Pentacam®
Anterior segment tomography produces a three-dimensional assessment of anterior and posterior corneal structures. The Pentacam uses rotating Scheimpflug imaging to generate cross-sectional scans of the cornea and anterior chamber, essential for detecting ectasia, refractive surgery screening and longitudinal monitoring. However,...
Scheimpflug vs. OCT in measuring corneal thickness
The authors report on the reproducibility and repeatability of corneal thickness measurements using three different Scheimpflug imaging cameras (Pentacam, Sirius and Galilei) and one Fourier-domain optical coherence tomography (OCT) system (RTvue-100). The rationale for this study is that corneal thickness...
Effect of trabeculectomy on corneal endothelial cell loss
This is a prospective study of 117 eyes for two years after trabeculectomy, to investigate the corneal endothelial cell density (CECD) by specular microscopy prior to and after surgery on a six monthly basis. At six, 12, 18 and 24...In conversation with Andrena McElvanney (President, MCLOSA)
We spoke to Andrena about MCLOSA's annual meeting this November, key developments in cornea and external eye disease, and plans for the association’s 30th anniversary. Andrena McElvanney (top, second from right) and the OSI council members. The Medical Contact Lens...Laser corneal refractive procedures – a review
Evolution of refractive surgery stays true to the quote of Theodore Roosevelt: “The more you know about the past, the better prepared you are for the future.” Refractive surgery is an evolving field, which thanks modern technologies for refining ideas...Intraocular lens choice in patients who have undergone previous corneal refractive surgery
Patients who underwent vision correction in their 20s to 40s are now entering their 50s and 60s, the typical starting age for cataract development [1]. Consequently, ophthalmologists are increasingly encountering patients whose corneal profiles have been surgically altered, requiring advanced...
Are corneal guttata an additional risk factor in complicated cataract surgery needing a future corneal transplant?
This registry-based cohort study from Sweden utilised data from the Swedish National Cataract Registry and the Swedish Cornea Transplant Registry. Patients who underwent phacoemulsification with a posterior intraocular lens between 2010 and 2012 numbered 192,476. Of these cases, 288 underwent...Crystalline keratopathy in monoclonal gammopathy of undetermined significance
Monoclonal gammopathies encompass a group of plasma cell disorders characterised by the excessive production of abnormal monoclonal immunoglobulins in the bloodstream [1]. This category includes multiple myeloma, monoclonal gammopathy of undetermined significance (MGUS), amyloidosis and other lymphoproliferative disorders. Monoclonal gammopathy...
Silent keratitis in failed graft
This study examined rates of asymptomatic keratitis in failed full thickness corneal grafts, which were not picked up clinically preoperatively. During a five year period 53 penetrating keratoplasties (PK) were performed for long-standing graft decompensation with stromal opacity and /...
Corneal neurotisation with an allograft
This is the first reported use of an acellular nerve allograft for corneal neurotisation. Seven patients received a 7cm long commercially prepared acellular nerve allograft. This was coapted to a functioning supratrochlear, supraorbital or infraorbital nerve and then tunnelled to...
