Association between cultures of contact lens and corneal scraping in Abstracts
contact lens related microbial keratitis
Das S, Sheorey H, Taylor HR, Vajpayee RB.
Centre for Eye Research Australia, University of Melbourne, Melbourne, Australia.
OBJECTIVE
To study the association between cultures of contact lens and corneal scraping in contact lens-related microbial keratitis.
METHODS
A retrospective analysis of the culture results of corneal scrapings and contact lenses of patients with contact lens-related microbial
keratitis who were initially seen at Royal Victorian Eye and Ear Hospital, Melbourne, Australia, between January 1, 2001, and December
31, 2004, was conducted. RESULTS: Fifty eye specimens of 49 patients were included in the study. Corneal scrapings and contact lenses
were culture positive in 17 eyes (34%) and in 35 eyes (70%), respectively. In 13 eyes, corneal scrapings and contact lenses yielded identical
organisms. Serratia marcescens was the most common organism isolated from the corneal scrapings and from the contact lenses.
CONCLUSION
Contact lens culture may sometimes give a clue to the organism involved in cases of microbial keratitis in which the corneal scraping is
culture negative and may help in choosing the appropriate antimicrobial therapy.
Application of Shape-based Analysis Methods to OCT Retinal Nerve
Fiber Layer Data in Glaucoma
Gunvant, Pinakin BS Optom, PhD, FAAO, Zheng, Yufeng PhD, Essock, Edward A. PhD, Parikh, Rajul S. MS, Prabakaran,
Selvaraj BS Optom, Babu, Jonnadula Ganesh BS Optom, Shekar, Garudadri Chandra MD, Thomas, Ravi MD
Journal of Glaucoma. 16(6):543-548, September 2007.
PURPOSE
To evaluate the performance of shape-based analysis [wavelet-Fourier analysis (WFA) and fast Fourier analysis (FFA)] applied to
retinal nerve fiber layer (RNFL) thickness values obtained from the optical coherence tomograph (OCT) to discriminate healthy and
glaucomatous eyes.
To compare the performance of the shape-based metrics to that of the standard OCT output measures (Inferior Average and Average
Thickness).
METHODS
RNFL values were obtained from 152 eyes of 152 individuals (83 healthy and 69 “mild”-stage perimetric glaucoma). WFA and FFA were
performed on the RNFL values and linear discriminant functions for both were obtained using Fisher linear discriminant analysis.
Performance was evaluated by calculating sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve (ROC
area).
RESULTS
The ROC area of the shape-based methods [0.94 (WFA) and 0.88 (FFA)] was greater than that of OCT metrics [0.81 (Inferior Average)
and 0.74 (Average Thickness)]. Specifically, WFAs performance was significantly better than both the FFA (P=0.009) and the Inferior
Average (P=0.001). Inferior average performed significantly better than Average Thickness (P=0.006).
CONCLUSIONS
The ability to differentiate glaucomatous from healthy eyes using stratus OCT measurements is improved by using these analysis
methods that emphasize the shape of the RNFL thickness pattern.

Low-Dose Mitomycin C as a Prophylaxis for Corneal
Haze in Myopic Surface Ablation

bDepartment of Ophthalmology and Visual Sciences, University of Louisville, Louisville, Kentucky

dDepartment of Quantitative Health Sciences, Cleveland Clinic Foundation, Cleveland, Ohio (M.X.)
PURPOSE
To evaluate the efficacy of low-dose (0.002%) mitomycin C (MMC) vs no prophylactic MMC (control) in reducing corneal haze after
surface laser ablation.
DESIGN
Two-year retrospective follow-up study performed in Jaipur, India.
METHODS
Ninety-two eyes with no MMC application and 83 eyes with 0.002% MMC application during laser epithelial keratomileusis (LASEK)
were analyzed in a retrospective chart review with one month, two months, three months, six months, one year, and two years of
postoperative follow-up. Postoperative haze, visual acuity, and efficacy ratio (EFFR) then were analyzed statistically.
RESULTS
The no-dose MMC and low-dose MMC groups were statistically similar except for a thinner corneal pachymetry (P < .001), higher
spherical equivalent error (P = .006), and smaller ablation zone (P = .009) in eyes not treated with MMC when subjected to univariate
analysis. Multivariate analysis was used to overcome the preoperative statistical differences among the two groups. Eyes treated with
low-dose MMC (0.002%) demonstrated statistically less haze at all postoperative time points and in each myopic subgroup (P < .001).
The postoperative uncorrected visual acuity (UCVA) and EFFR, however, showed no difference between the groups, except for better
EFFR with MMC at one month (P < .001) and two months (P = .034).
CONCLUSIONS
Low-dose MMC (0.002%) in eyes after LASEK results in less corneal haze than in eyes not receiving this agent. Concerns regarding the
potential toxicity of MMC make a 10-fold less concentration more desirable in refractive surgery. Further comparative study of low- vs
higher-dose MMC is recommended to characterize its clinical benefit fully.

injection on Iris fluorescein angiography remains a challenge despite many advances. Although PRP is
considered the standard treatment of retinal ischaemia, the best
alternative method is still undetermined. Consideration of visual
potential is also important. If there is no useful vision, the goal of
therapy becomes patient comfort and the management protocol
may differ. In conditions precluding PRP due to media opacities,
other modalities should be considered including pan-retinal
cryotherapy, and trans-scleral diode laser retinopexy.2

This is the world's first international review journal
incorporating a video DVD. The journal publishes invited
review articles from top glaucoma experts worldwide and
also includes diagnostic and surgical videos in the DVD.
The journal covers each subspeciality of glaucoma including :
basic and clinical research, epidemiology, biostatistics, genetics,
pathophysiology, laboratory methods, clinical examination,
perimetry, new structural and functional tests, anterior
segment imaging, ocular blood flow, pediatric glaucoma, angle
closure glaucoma, open angle glaucoma, secondary glaucoma,
medical management, laser therapy, glaucoma and combined
cataract glaucoma -surgical techniques, neuroprotection,
health economics, quality of life and visual rehabilitation.
The journal has a unique video section in the DVD which
show-cases basic and advanced glaucoma surgical techniques,
management of complications, includes diagnostic techniques
and video assisted instruction courses and lectures.
