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 /...

Nanofiber-based hydrogels prevent capsular opacification

Lens refilling is the replacement of the lens with a silicone polymer in an otherwise intact lens capsule. However, capsular opacification (CO), resulting in reduced visual acuity, is a major complication of these injectable accommodating lenses. Opacification is due to...

High-fluence collagen cross-linking

The authors treat seven eyes with progressive keratoconus with a high energy (18mW) for five minutes delivering a total energy similar to that suggested by the original Dresden protocol (3mW for 30mins). All eyes had a thickness >400µm following epithelial...

Vision loss during Eylea treatment for AMD

This report investigated patients who lost more than two lines of vision despite periodic injections of aflibercept and explored the factors associated with vision loss. One hundred and ninety-six eyes were included in this study over a two year period....

EDTA chelation for band keratopathy

The authors describe a retrospective analysis of 89 eyes from 72 patients who underwent ethlenediamine tetra-acetic acid (EDTA) chelation for band keratopathy. The ratio of R:L eye was 41:48. The mean age was 71 years (range 18-93 years). Thirty-two out...

Recurrent corneal erosions secondary to isotretinoin use

Isotretinoin (13–cis-retinoic acid) is the first line treatment for moderate to severe nodulocystic or papulopustular acne [1,2]. Although it is a safe medication, it has several adverse side-effects, including ophthalmic manifestations, as shown in Table 1 [3]. These side-effects need...

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...

Corneal thickness in patients with diabetic peripheral neuropathy

This cross-sectional study assessed corneal thickness in association with diabetic peripheral neuropathy (DPN) severity. The study also tried to identify the layer of the cornea most affected by DPN status. Performed at the University of Michigan the study included three...

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...

IOP and reversibility of RPE detachment

The authors describe how three patients with retinal pigment epithelium (RPE) detachment showed a reduction or disappearance of an RPE detachment immediately following prone dark room test (PDRT). The authors performed spectralis OCT on 140 angle closure subjects before and...

Cell injection therapy for endothelial failure

This is a prospective observational study involving 11 eyes of 11 patients with pseudophakic endothelial failure who underwent human corneal endothelial cell culture (hCEC) injection therapy for endothelial failure. This study aimed to evaluate the long-term five-year postoperative data for...

Apr/May 2017 Quiz

History A five-month-old baby was seen in clinic with bilateral congenital corneal opacities. The right cornea is shown in Figure 1. Figure 1. Examination revealed corneal oedema and opacities of Descemet’s membrane and endothelium with a few vesicular lesions. Corneal...
