At 9-month follow-up, the right eye showed a clear cornea with an attached graft and the left eye revealed recurrence of central band keratopathy for which repeat EDTA chelation was successfully performed.

Recurrent band keratopathy coincident with endothelial dysfunction in iridocorneal endothelial syndrome can be repeatedly treated with EDTA chelation, whereas endothelial keratoplasty might be delayed until the time point of corneal decompensation.

To report the first case of Paenibacillus glucanolyticus, a spore-forming bacteria, to be isolated in a human ocular infection.

We describe a severe case of noncontact lens-related microbial keratitis due to P. glucanolyticus presenting with a large corneal abscess, severe ocular inflammation, and a large epithelial defect.

The corneal scrapes with no growth initially cultured P. glucanolyticus on blood agar after 48 hours, with sensitivity to gentamicin and fluoroquinolones. No other organism was cultured. The patient had severe keratitis with a protracted course requiring cyanoacrylate glue patching because of keratolysis and perforation. The patient may benefit from a penetrating keratoplasty and extracapsular cataract extraction in due course to aid visual rehabilitation.

This is the first reported ocular case of P. glucanolyticus demonstrating its bacterial virulence and pathogenic potential when infecting the cornea. Rapid identification with newer technology enable us to accurately identify these opportunistic bacteria and may give a more favorable visual outcome as correct sensitivities lead to timely treatment administration.

To report a rare case of herpes virus type 2-related conjunctivitis, resistant to aciclovir (ACV).

Case report and review of literature.

A 28-year-old human immunodeficiency virus-positive man presented with chronic, recurrent follicular conjunctivitis. Multiplex reverse transcription polymerase chain reaction assay testing was positive for herpes simplex virus (HSV); subsequent typing with HSV assay revealed the presence of HSV type 2. Oral ACV failed to control the disease, and the patient continued to worsen clinically until resistance testing was performed. This revealed an M183stop within thymidine kinase, thus confirming the suspected resistance. The patient improved after 14 days of high-dose continuous intravenous infusion of ACV.

This is a rare case of isolated conjunctivitis due to herpes virus type 2, in an human immunodeficiency virus-positive patient, which was found to be resistant to ACV. Drug-resistant HSV is likely to emerge as an important clinical entity in the future, increasing the need for new drugs with novel mechanisms of action.

To examine the rate and risk factors for band keratopathy after herpes zoster ophthalmicus (HZO) and the outcomes of ethylenediaminetetraacetic acid (EDTA) treatment.

This is a retrospective review of all subjects with HZO seen at Auckland District Health Board between January 2006 and December 2016.

A total of 869 subjects with HZO were included in the study. Median follow-up was 6.3 years (total 5504.4 patient-years). Band keratopathy developed in 13 subjects (1.5%). On multivariate analysis, older age at onset [hazard ratio (HR), 1.092; P = 0.034], intraocular pressure ≥30 mm Hg at presentation (HR, 5.548; P = 0.013), and number of recurrences (HR, 1.849; P < 0.001) were associated with increased risk for band keratopathy. Corneal melt occurred in 22 subjects (2.5%) during the follow-up period. On multivariate analysis, uveitis (HR, 8.618; P = 0.004) and disodium EDTA chelation (HR, 8.666; P < 0.001) were associated with increased risk for corneal melt. EDTA chelation was performed in 8 subjects. Corneal melt occurred after EDTA chelation in 4 subjects, and corneal perforation occurred in 2 subjects. One subject was eviscerated due to severe endophthalmitis after repeated corneal perforation and another required enucleation for recurrent corneal melt and microbial keratitis.

Band keratopathy is an uncommon complication of HZO. Treatment with EDTA chelation might be associated with a significant risk for severe complications in these eyes and should be approached with caution.

To determine whether using younger donor tissue for Descemet membrane endothelial keratoplasty (DMEK) surgery influences clinical outcomes.

Scroll tightness, unscrolling time, rebubble rate, and preoperative and 3- and 6-month postoperative endothelial cell density (ECD) and endothelial cell loss (ECL) were compared for 661 DMEK grafts prepared from younger (aged younger than 50 yrs, n = 81) and older donors (aged 50 yrs or older, n = 580) with Student t test, χ test, or Mann-Whitney U test.

There was no difference in overall unscrolling time (younger donors 3.1 ± 3.1 min, older donor 2.9 ± 2.7 min, P = 0.503). Experienced faculty surgeons, compared with fellows, had a significantly lower unscrolling times for both younger donors (2.4 ± 2.3 vs. DMXAA 4.6 ± 3.9 min, P = 0.002) and older donors (2.5 ± 2.1 vs. 3.7 ± 3.3 min, P <0.001). Rebubble rates were not statistically different between younger (12.3%) and older donors (15.0%, P = 0.527). Three-month ECD was higher in grafts from younger compared with that in those from older donors (2138 ± 442 vs.
