PURPOSE: To report a case of corneal melting associated with the use of the topical nonsteroidal anti-inflammatory agent Nepafenac. METHODS: Case report and literature review. RESULTS: A 62-year-old woman with a complicated ocular history developed corneal melting associated with the use of Nepafenac. On discontinuation of Nepafenac, the melt rapidly resolved. CONCLUSIONS: Topical nonsteroidal anti-inflammatory agents have been associated with corneal ulceration and stromal melts. This is, to our knowledge, the first reported case involving the new agent, Nepafenac. (09/2007)

Department of Ophthalmology, Loma Linda University, Loma Linda, California, USA. email@example.com PURPOSE: To compare the accuracy of intraocular lens (IOL) power calculations using 4 formulas: Hoffer Q, Holladay 1, Holladay 2, and SRK/T. SETTING: Tertiary care center. METHODS: This study was a retrospective comparative analysis. Immersion ultrasound biometry (axial length, anterior chamber depth, and lens thickness), manual keratometry, and postoperative manifest refraction were obtained in 643 eyes of consecutive patients who had routine uneventful cataract surgery with implantation of 1 of 2 IOLs using the same operative technique by the same surgeon. Biometric data were entered into each of the 4 IOL power calculation formulas, and the results were compared to the final manifest refraction. An optimized lens constant was used for each formula. Results were also stratified into groups of short, average, medium long, and very long axial length

Cornea. 2006 Oct;25(9):1115-7 . (): -. Department of Ophthalmology, Loma Linda University School of Medicine, Loma Linda, CA 92354, USA. firstname.lastname@example.org PURPOSE: To report a case of clinically significant post-laser in situ keratomileusis (LASIK) epithelial ingrowth successfully treated with a combined technique of mechanical debridement, flap suturing, and fibrin glue application. METHODS: A retrospective case report. RESULTS: A 42-year-old female patient underwent LASIK and an enhancement procedure in 1998 and 2002, respectively. Two years after her enhancement, she developed severe, visually significant epithelial ingrowth. Treatment was undertaken using a combination of mechanical debridement, flap suturing, and fibrin glue application. No recurrence was found during a 15-month follow-up period. No adverse effects were seen with this approach. CONCLUSION: Severe progressive epithelial ingrowth may be treated successfully with a combination of mechanical debridement, flap suturing, and fibrin glue application.

Department of Ophthalmology, Loma Linda University, Loma Linda, CA 92354, USA. email@example.com PURPOSE: We report the occurrence and outcome of a severe late-onset traumatic dislocation of a laser in situ keratomileusis (LASIK) flap with loss of central flap tissue. METHODS: Case report. RESULTS: A 40-year-old woman underwent uncomplicated bilateral LASIK surgery, followed 5 years later by an enhancement procedure in both eyes. Ocular trauma with a power sander occurred 6 years after LASIK and 1 year after the enhancement procedure. The flap was found to have an almost complete tear from the nasal hinge and a central tissue defect. After irrigating, repositioning, and stabilizing the flap with 2 nylon sutures, a bandage contact lens was placed. The patient was treated with topical antibiotic and steroid drops. Stage 2 diffuse lamellar keratitis developed, which responded to topical treatment. Ten weeks after injury, the patient regained an uncorrected visual acuity of 20/20-1. CONCLUSION: Late-onset trauma to the LASIK flap can result in flap dehiscence and tissue loss. Prompt and appropriate management can lead to an excellent visual outcome even in severely traumatized dislocated LASIK flaps.

J Cataract Refract Surg. 2006 Nov;32(11):1926-31. . (): -. House Staff Office, Loma Linda University, Loma Linda, California, USA. PURPOSE: To compare a monocular and a binocular multiple-measurement digital infrared pupillometers for measuring scotopic pupil diameter. SETTING: Department of Ophthalmology, Loma Linda University, Loma Linda, California, USA. METHODS: Scotopic pupil size was measured after 1 minute of dark adaptation in 42 eyes of 21 volunteers. Measurements were taken twice each with 2 multiple-measurement digital infrared pupillometers, the monocular pupillometer (Neuroptics, Inc.), and the binocular pupillometer (P2000D, Procyon, Ltd.) Intraclass correlation coefficients (ICC) and limits of agreement (LOA) were used to measure repeatability and agreement of measures with each instrument and between instruments. The Wilcoxon signed rank test was used to compare variability of measurements within each instrument. RESULTS: The mean scotopic pupil size was 4.79 mm +/- 0.95 (SD) with the Procyon and 4.86 +/- 0.93 mm with the Neuroptics. Repeatability and agreement tests for the Procyon measures showed the following: ICC, 0.954; 95% confidence interval (CI), 0.916-0.975; LOA, -0.60 to 0.56; range, 1.16. The Wilcoxon signed rank test of variability gave a Z score of -2.53 (P = .01, 2 tailed). The repeated measures testing with the Neuroptics pupillometer showed the following: ICC, 0.985; 95% CI, 0.972-0.992; LOA, -0.39 to 0.26; range, 0.64; Z score, -1.15 (P = .25, 2-tailed). Repeatability and agreement tests for measures between instruments showed the following: ICC, 0.954; 95% CI, 0.916-0.975; LOA, -0.60 to 0.50; range 1.11. CONCLUSIONS: There was a high repeatability and agreement in scotopic pupil diameter for repeated measures within each device and measurements between the devices. Differences in variability in scotopic pupil diameter evaluated by the Wilcoxon signed rank test were significant only with the Procyon pupillometer. PMID: 17081898 [PubMed - indexed for MEDLINE]
