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...

Customised corneal crosslinking with supplemental oxygen

In this prospective interventional case series, the authors investigate using supplemental oxygen delivery during epithelium-on corneal crosslinking (CXL) with specially designed oxygen delivery goggles. Twenty-seven eyes of 24 patients underwent epi-on CXL with Riboflavin and Ultraviolet-A irradiation. At six months...

Comparison of methods of central corneal thickness measurement in glaucoma

This prospective study was done to compare the accuracy and reproducibility of central corneal thickness measured by hand-held and disc-mounted ultrasound pachymeter in glaucoma patients. Sixty-five patients were included in the study. Patients with corneal diseases, corneal astigmatism >3 diopters...

Effect of preservative free fluoroquinolones on human corneal epithelial cells in vitro

Fluoroquinolones, including second generation (ofloxacin and ciprofloxacin), third generation (levofloxacin and tosufloxacin) and fourth generation (gatifloxacin and moxifloxacin), are a group of bactericidal agents used to treat multiple ocular infections. The third and fourth generation fluoroquinolones have enhanced Gram-positive activity...

Pentacam vs. IOL Master keratometry measurement in IOL power calculations

The IOL Master measures only the anterior corneal curvature and estimates the total corneal power by assuming a fixed relationship between the anterior and posterior corneal surface. The Pentacam measures both the anterior and posterior corneal surface and therefore calculates...

A step-by-step approach to the diagnosis and management of Sands of Sahara Syndrome

Sands of Sahara syndrome (diffuse lamellar keratitis) is a rare postoperative complication of Laser in situ keratomileusis (LASIK). Its estimated prevalence is reported to be 2-4% among LASIK cases [1], despite that, it is more likely to be encountered by...

Case series of toxic anterior segment syndrome

Herein we report two cases of toxic anterior segment syndrome (TASS) following uneventful cataract surgery. Both patients presented 24 hours after their uneventful operations with painless blurred vision in the operated eye. The inflammatory reaction was controlled successfully with an...

Is DSAEK or DMEK better for failed penetrating keratoplasty (PKP)?

This retrospective study involved 52 patients with failed penetrating keratoplasty. Twenty-eight eyes underwent Descemet membrane endothelial keratoplasty (DMEK) and 24 eyes underwent Descemet stripping automated endothelial keratoplasty (DSAEK). Data collection included demographic characteristics, number of previous corneal transplants, previous glaucoma...

How long to air tamponade after DMEK?

This interventional case series looked at the influence of different intraoperative air tamponade times on graft adherence after descemet membrane endothelial keratoplasty (DMEK). A total of 117 eyes with Fuchs endothelial corneal dystrophy (FECD) that underwent DMEK were included. Patients...

Glaucoma patients can monitor and treat their own IOP!

Simerdip Kaur takes a look at the latest ophthalmology-related stories in the news. Headline: Glaucoma patients can monitor and treat their own IOP! It is well known that poorly controlled intraocular pressure (IOP) is a leading risk factor for glaucoma...

Portable corneal topography – exploration of a prototype

Ophthalmic imaging devices, such as corneal topographers, are not widespread in the developing world. A small device that connects to a smartphone might be a solution to improve developing nation access to corneal imaging. I recently had the opportunity to...
