Central corneal and epithelial thickness measured by Fourier domain OCT
This study examined intraobserver and interobserver reproducibility of corneal thickness (CT) and epithelial thickness (ET) measurement of Fourier domain OCT (RTVue) in 23 healthy volunteers. RTVue is capable of producing 26,000 A scans per second with depth resolution of 5µm....
Allografts in limbal stem cell deficiency
This prospective comparative study compared outcomes of live related limbal allograft (Lr-CLAL) versus cadaveric keratolimbal allograft (KLAL) in limbal stem cell deficiency secondary to ocular burns. Twenty patients were randomly allocated into each group. The Lr-CLAL group had a significant...
Meibomian gland dropout in patients with dry eyes
In this prospective study 264 patients with symptoms of dry eye were examined with a non-contact meibography system to assess the morphological changes in their meibomian glands. These patients were not previously diagnosed with meibomian gland dysfunction and patients with...
Vital dyes in ophthalmology
This comprehensive review gives an excellent summary of the uses and properties of the different dyes available to aid better visualisation and diagnoses in ophthalmology. The authors clearly display the pharmacological properties, molecular details, osmolarity and indications in clinical ophthalmology...
Stereo distance in XT
The test distance effect on stereoacuity was explored in a population with intermittent exotropia along with use of two types of stereograms with crossed and uncrossed disparity. At near and distance distances, the median for both disparities was 60”; 79%...Principles of contact lens fitting in keratoconus
Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...Les Misérables
I recently had the signal pleasure of undergoing Part 2 of the FRCOphth exit exam and could not help but wonder at how examiners could on the whole be easily categorised into certain subtypes which readers may find fascinating. This...Ophthalmology elective: a local experience
Dr Rajan Sondh talks about medical electives and how he believes they are an opportunity to explore career interests, giving undergraduates an opportunity to develop skills in areas that they wouldn’t normally encounter on placements. Typically, electives are taken abroad,...
Influence of FLEx and SMILE on corneal nerve density and ocular surface
This was a prospective study designed to compare the influence of femtosecond lenticule extraction (FLEx) and small incision lenticule extraction (SMILE) on the corneal nerve density and ocular surface for myopic correction. Thirty patients underwent bilateral lenticule extraction. One eye...
B-scan ultrasonography
B-scan ultrasonography is commonly employed for the diagnosis and follow-up of ocular trauma. This retrospective study looked at the accuracy and predictive ability of B-scan ultrasonography following open globe repair. Of the 965 patients identified with open globe injuries at...
