A missed intraocular telescope – an opportunity to re-focus the evidence

Intraocular telescopes allow magnification of the image so that it would be projected into a larger area of the macula, this makes the central defect caused by dry age-related macular degeneration (AMD) smaller. The most common approach is a Galilean...

Transcriptomic analysis of ocular tissues

Transcriptomics is defined as the analysis of the complete set of RNA transcripts present in a cell under different circumstances, quiescent versus challenge, by microarray analysis. Comparison of transcriptomes identifies genes that are differentially expressed in different cell populations under...

Another plant-based remedy for the eye?

Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are based on facts and which are ‘fake news’. Headline: Another plant-based remedy for the eye? What do the nicknames Mary Jane, tea, and 420 all...

What you learn after performing 10,000 cataracts

What do you do when the anterior chamber shallows, or the zonules give way? How do you handle the stubborn epinuclear plate? Raymond Radford shares the benefit of his experience when dealing with tricky cataract surgery. Firstly, you realise you...

Risks factors for graft preparation failure in DMEK

Diabetes mellitus (DM) makes it more difficult to prepare descemet membrane epithelial keratoplasty (DMEK) grafts due to the ‘stickiness’ of Descemet’s membrane. This retrospective study examined a classification system, where donors were scored points according to their DM related risk...

Tear film thickness after treatment with artificial tears in patients with moderate dry eye disease

In recent years artificial tear drops addressing tear film osmolarity have come onto the market. Increased tear evaporation and reduced tear volume results in tear hyperosmolarity. This triggers an inflammatory process leading to apoptosis of goblet and epithelial cells. Trehalose,...

Management of diffuse OSSN with topical chemotherapy

Ocular surface squamous neoplasia (OSSN) can be localised to the conjunctiva or, less commonly, diffusely spread over the conjunctiva and cornea. Localised OSSN can be treated by surgical removal with adjuvant cryotherapy and chemotherapy with low rates of recurrence. Diffuse...

Tacrolimus for endothelial rejection

This double-blinded randomised controlled trial tested the use of adjuvant topical Tacrolimus drops in cases of acute endothelial rejection in penetrating keratoplasty (PK). Patients with typical signs of endothelial rejection were randomised to receive either steroid therapy with topical Tacrolimus...

Comparison of SIA from femtosecond laser and manual CCIs for cataract surgery

This study group compared the differences in surgically induced astigmatism (SIA) vector, flattening effect, torque and wound architecture following both femtosecond laser and manual clear corneal incisions (CCIs). A double-armed, randomised, prospective case series was conducted. Cataract surgery was performed...

IOL power calculation formulas for myopic eyes undergoing cataract surgery after excimer laser

The authors set out to compare the accuracy of four no-history formulas: Barrett True-K, Haigis-L, Shammas-PL, and Triple-S to calculate the intraocular lens (IOL) power in eyes with previous myopic photorefractive keratectomy or laser in situ keratomileusis, according to their...

Effects of ML4 on the eye

Mucolipidosis type IV (ML4) is an autosomal recessive lysosomal storage disease and is caused by variants of the MC0LN1 gene. It often presents in young individuals with eye and ocular adnexa issues. The authors present a case report and literature...

Treatment of progressive keratoconus

This study aimed to analyse the clinical results of accelerated iontophoresis-assisted epithelium corneal cross-linking (i-ON CXL) to evaluate the risk factors for keratoconus progression after treatment, and the safety and efficacy of re-treatment using epithelium-off CXL protocol in paediatric patients....
