The article discusses the results of the study which examines the outcome of utilizing ketorolac tromethamine 0.4%, a non-steroid anti-inflammatory agent (NSAID), and steroid on patients undergoing cataract surgery. According to Dr. John R. Wittpenn Jr., the use of NSAID plus steroid improves the visual outcome of the patient by reducing the incidence of retinal thickening and cystoid macular edema. The study suggests that NSAIDs are advantageous in all cataract surgery cases.

- Abstract
Purpose: Nocardia keratitis is a rare type of infectious keratitis and may mimic other corneal diseases and lead to delay in diagnosis. This case illustrates how Nocardia often escapes accurate diagnosis due to its insidious onset, variable clinical manifestations, and unusual characteristics on cultures., Observation: The patient presented with an epithelial defect and superior pannus and scarring, which was misdiagnosed as superior limbic keratoconjunctivitis (SLK) and herpes simplex virus (HSV) keratitis. Repeat corneal scraping cultures, smears, and conjunctival biopsy were necessary to elucidate the diagnosis. It can be effectively treated with the intravenous preparation of trimethoprim-sulfamethoxazole 80 mg/mL (brand name SEPTRA) used topically as eye drops., Conclusion: The diagnosis of Nocardia keratitis relies on a high clinical suspicion and a prompt corneal scraping with culture. Due to its potential for rapid resolution with early therapy, it is important to isolate Nocardia early in its disease course., Importance: Topical amikacin had been the standard of care for Nocardia keratitis for many years. However, recently there is increasing resistance of Nocardia to amikacin. SEPTRA offers an alternative therapy. Nocardia keratitis mimics other infectious and inflammatory etiologies so rapid diagnosis and treatment is critical in the prevention of long-term complications., (© 2021 The Authors.

- Abstract
Purpose: Topical nonsteroidal antiinflammatory drugs (NSAIDs) are administered topically for a variety of ophthalmologic conditions. Brand diclofenac and brand ketorolac were previously shown to have topical anesthetic effects in addition to analgesic effects. Using the same method, we measured similar anesthetic effects of the 4 currently available topical NSAIDs--generic diclofenac, generic ketorolac, brand bromfenac, and brand nepafenac., Methods: Baseline corneal sensitivity was measured on 10 healthy adult volunteers with a Cochet-Bonnet esthesiometer. One drop of the agent being studied was applied to the right eye every 5 minutes for a total of 4 drops. Corneal sensitivity was measured immediately after the last topical application and every 15 minutes for 60 minutes. After a 1-week washout period, a different agent was studied until all 4 NSAIDs were evaluated., Results: Corneal sensitivity profiles over time were similar for all NSAIDs. Corneal sensitivity decreased significantly from baseline immediately after topical application remaining flat from 0 to 30 minutes and then rising from 45 to 60 minutes back toward baseline in all treatment groups (P < 0.001). The maximal absolute drop in corneal sensitivity as measured by pressure thresholds was greatest for diclofenac [28.6 mm (95% confidence intervals {CI}, 19.8-37.4)], followed by ketorolac [21.1 mm (95% CI, 15.1-27.1)], bromfenac [16.9 mm (10.7-23.1)], and nepafenac [16.4 mm (95% CI, 12.7-20.1)]. Only diclofenac and nepafenac were statistically different in maximal decrease in sensitivity., Conclusions: All 4 currently available NSAIDs demonstrated anesthetic effects similar to brand diclofenac and brand ketorolac.

- Abstract
Purpose: To evaluate the effect of decreasing topical cyclosporine 0.05% (tCSA) (Restasis; Allergan, Irvine, CA) from twice-daily dosing to once-daily dosing in patients who have already completed 12 months of twice-daily therapy for dry eye disease., Design: Prospective, randomized, single-masked, parallel group comparison., Participants: One hundred patients who had already been treated with tCSA twice daily for more than 1 year were randomized either to continue tCSA twice daily (n = 50) or to decrease tCSA once daily (n = 50)., Methods: Clinical measurement of dry eye variables was performed for all patients at baseline, 3 months, and 6 months. Mean data were used for within-group (longitudinal analysis) and between-group comparisons (once daily vs. twice daily)., Main Outcome Measures: Fluorescein tear break-up time, corneal fluorescein staining score, lissamine green staining score, Schirmer tear test, and ocular surface disease index., Results: At the end of the study, patients whose treatment dose was decreased to once daily demonstrated statistically significant improvement in tear break-up time [4.13 seconds (n = 37) vs. 3.11 seconds at baseline (n = 50); P = 0.0003] and lissamine green staining score [4.42 (n = 37) vs. 6.51 at baseline (n = 50); P = 0.024]; fluorescein staining score, Schirmer test results, and ocular surface disease index did not change significantly (P > 0.05). Furthermore, the once-daily group demonstrated significantly superior ocular surface disease index compared with the twice daily group [15.91 (n = 37) vs. 22.62 (n = 48); P = 0.0496]. The remaining outcome measures between once daily and twice daily were not significantly different (P > 0.05). Seven of 50 patients (14%) in the once-daily group (vs. 0% in the twice-daily group) ended the study early because of worsening dry eye symptoms (P < 0.05) and went back to twice-daily dosing., Conclusions: For patients with dry eye that has been controlled with tCSA twice daily for at least 1 year, decreasing to tCSA once daily may still allow suppression of the dry eye disease.

- Abstract
Background/aims: To determine whether patient-reported improvement in symptoms of dry eye syndrome, activities of daily living, and other quality-of-life measures after treatment with hydroxypropyl cellulose ophthalmic inserts correlates significantly with physician assessment of clinical outcomes., Methods: Patient registry of those treated for 1 month with inserts as monotherapy or in combination with existing treatments for moderate-to-severe dry eye syndrome. A total of 520 participants were enrolled. Of those, 418 patients completed the study. Results of this registry were evaluated and correlations were calculated to determine whether patient-reported symptoms, quality of life, and changes in disease severity based on the Ocular Surface Disease Index, and activities of daily living outcomes are predictive of physician assessment of clinical signs, symptoms, and adherence to therapy., Results: Most patients reported overall improvement in their condition. Patient-reported improvements in the symptoms of dry eye syndrome and activities of daily living were significant predictors of physician assessment of compliance with insert therapy, improvement in symptoms and clinical signs, effectiveness of therapy, and acceptance of use as adjunctive therapy., Conclusions: Patient-reported symptoms and activities of daily living are predictors of patient compliance and treatment success with the use of inserts, as reported by treating physicians. The benefits were additive to the standard of care that was continued during the course of the study. These predictors, along with clinical diagnostic tests, can be used by eye care professionals to assess the efficacy of treatment for moderate-to-severe dry eye syndrome quickly and reliably.

- Abstract
Purpose: To evaluate the efficacy of cyclosporine 0.05% in alleviating dry-eye signs and improving visual quality after multifocal intraocular lens (IOL) implantation., Setting: Private practice and university medical center, New York, New York, USA., Methods: This randomized prospective contralaterally controlled double-masked trial comprised patients scheduled to have bilateral phacoemulsification with implantation of a refractive multifocal IOL (ReZoom). Patients received twice-daily cyclosporine 0.05% in 1 eye and an artificial tear in the other eye from 1 month before to 2 months after second-eye surgery. Outcomes were evaluated at baseline and 2 months after second-eye surgery., Results: The study enrolled 28 eyes of 14 patients. At baseline, there were no statistically significant between-group differences in outcome measures. Two months postoperatively, the cyclosporine group had significantly lower mean uncorrected distance visual acuity than the artificial tear group (0.11 logMAR +/- 0.03 [SD] [20/25 Snellen equivalent] versus 0.19 +/- 0.05 logMAR [20/30]; P = .045) as well as significantly lower mean corrected distance visual acuity (0.0 +/- 0.02 logMAR [20/20] versus 0.1 +/- 0.02 logMAR [20/25]; P = .005) and corneal staining scores (0.210 +/- 0.07 versus 0.645 +/- 0.18; P = .034). Treatment with cyclosporine 0.05% also improved contrast sensitivity, conjunctival staining, and tear breakup time. Significantly more patients preferred the eye treated with cyclosporine 0.05% to the eye treated with artificial tears (57.1% versus 14.3%; P = .007)., Conclusion: Cyclosporine 0.05% therapy reduced dry-eye signs and improved visual quality after multifocal IOL implantation., Financial Disclosure: No author has a financial or proprietary interest in any material or method mentioned.

- Abstract
Purpose: A multicenter, 2-visit, open-label, 4-week study was conducted to determine the acceptability of hydroxypropyl cellulose ophthalmic inserts in adult patients with a history of dry eye syndrome (DES)., Methods: At visit 1, patients (N = 520) were evaluated, screened by slit-lamp biomicroscopy, and completed the Ocular Surface Disease Index (OSDI), a validated measure of quality of life. Patients were trained in the proper placement and use of hydroxypropyl cellulose ophthalmic inserts and were contacted by telephone on day 3 of the study. At week 4, patients were given a clinical evaluation and completed a second questionnaire. Answers determined changes in symptoms and quality of life. Adverse events were monitored throughout the study., Results: Four hundred eighteen patients completed the study and reported significant improvements in discomfort, burning, dryness, grittiness, stinging, and light sensitivity (P = .05) after 4 weeks use of hydroxypropyl cellulose ophthalmic inserts. Significant improvements in clinical signs (keratitis, conjunctival staining, and tear volume) were reported. Contact lens wearers reported significant improvements similar to nonwearers, with a strong trend toward improvement in light sensitivity. Mean OSDI total scores, measuring quality of life, significantly improved by 21.3% (from 41.8 +/- 22.38 to 32.9 +/- 21.97, P < or = .0215). The most commonly reported adverse event leading to discontinuation was blurred vision, observed in 8.7% of patients (n = 45). Compliance during the study was good; 41.5% of subjects were fully compliant. Of the 58.5% of subjects who missed doses, the majority (69.4%) missed only one to five., Conclusions: Hydroxypropyl cellulose ophthalmic inserts significantly reduced symptoms and clinical signs of moderate to severe DES. They also significantly improved DES in patients wearing contact lenses. Patients experienced a statistically significant improvement in quality of life, as measured by the OSDI, of 21.3%.

- Abstract
Purpose: To evaluate whether adding perioperative topical ketorolac tromethamine 0.4% improves cataract surgery outcomes relative to topical steroids alone in patients without known risk factors for cystoid macular edema (CME)., Design: Prospective, randomized, investigator-masked, multicenter clinical trial., Methods: Patients scheduled to undergo phacoemulsification and with no recognized CME risks (diabetic retinopathy, retinal vascular disease, or macular abnormality) were randomized to receive either prednisolone acetate 1% 4 times daily (QID) alone (steroid group; n = 278) or prednisolone 1% QID plus ketorolac 0.4% QID (ketorolac/steroid group; n = 268) for approximately four weeks postoperatively. In the ketorolac/steroid group, patients also received topical ketorolac 0.4% QID for three days preoperatively. In both groups, patients received four doses of ketorolac 0.4% one hour before surgery. Patients with capsular disruption or vitreous loss intraoperatively were exited from the study. Outcome measures included CME incidence, retinal thickness as measured by optical coherence tomography (OCT), best-corrected visual acuity, and contrast sensitivity., Results: No patients in the ketorolac/steroid group and five patients in the steroid group had clinically apparent CME (P = .032). Based on OCT, no ketorolac/steroid patient had definite or probable CME, compared with six steroid patients (2.4%; P = .018). In the ketorolac/steroid group, mean retinal thickening was less (3.9 microm vs 9.6 microm; P = .003), and fewer patients had retinal thickening of more than 10 microm as compared with the steroid group (26% vs 51%; P < .001)., Conclusions: This study suggests that adding perioperative ketorolac to postoperative prednisolone significantly reduces the incidences of CME and macular thickening in cataract surgery patients already at low risk for this condition.

- Abstract
Objective: To evaluate the use of topical cyclosporine, 0.05% (Restasis; Allergan Inc, Irvine, California), for the treatment of mild, moderate, and severe dry eye disease unresponsive to artificial tears therapy., Methods: This was a prospective clinical study. One hundred fifty-eight consecutive patients with dry eye disease unresponsive to artificial tears therapy were divided into 3 groups of disease severity: mild, moderate, and severe. Patients were evaluated using the Ocular Surface Disease Index for symptomatic improvement, tear breakup time, fluorescein staining, lissamine green staining, and Schirmer testing. Patients were observed for 3 to 16 months. The main outcome measure was improvement in disease., Results: Forty-six of 62 patients with mild dry eye disease (74.1%), 50 of 69 with moderate disease (72.4%), and 18 of 27 with severe disease (66.7%) showed improvement, with 72.1% improving overall., Conclusions: Topical cyclosporine shows beneficial effects in all categories of dry eye disease. Symptomatic improvement was greatest in the mild group and the best results in improvement of disease signs were in patients with severe dry eye disease.

- Abstract
Purpose: To elucidate risk factors, clinical course, visual outcomes, and treatment of culture-proven methicillin-resistant Staphylococcus aureus (MRSA) infectious keratitis following refractive surgery., Design: Interventional case series., Methods: Multicenter chart review of 13 cases of MRSA keratitis following refractive surgery and literature review., Results: Thirteen eyes of 12 patients, nine of whom were either healthcare workers or exposed to a hospital surgical setting, developed MRSA keratitis following refractive surgery. All patients presented with a decrease in visual acuity and complaints of pain or irritation in the affected eye. Common signs on slit-lamp biomicroscopy were corneal epithelial defects, focal infiltrates with surrounding edema, conjunctival injection, purulent discharge, and hypopyon. All patients were diagnosed with infectious keratitis on presentation and treated with two antibiotics. All eyes were culture-positive for MRSA., Conclusions: According to a computerized MEDLINE literature search, this is the first case series of MRSA infectious keratitis following refractive surgery, the first reports of MRSA keratitis after refractive surgery in patients with no known exposure to a healthcare facility, the first report of MRSA keratitis after a laser in situ keratomileusis (LASIK) enhancement, and the first reports of MRSA keratitis after prophylaxis with fourth-generation fluoroquinolones. MRSA keratitis is a serious and increasing complication following refractive surgery. Patients with exposure to a healthcare environment should be considered at additional risk for developing MRSA keratitis. However, in addition, surgeons should now be vigilant for community-acquired MRSA. Prompt identification with culturing and appropriate treatment of MRSA keratitis after refractive surgery is important to improve visual rehabilitation.

- Abstract
Purpose: To assess the clinical benefit, relative efficacy, and pharmacokinetic-response curve of preoperative and postoperative ketorolac tromethamine 0.4% (Acular LS) to improve outcomes during and after cataract surgery., Setting: Private clinical practice., Methods: One hundred patients were randomized in a double-masked fashion to 4 groups of 25 to receive ketorolac for 3 days, 1 day, or 1 hour or a placebo before phacoemulsification. All treatment groups received ketorolac 0.4% for 3 weeks postoperatively; the placebo group received vehicle. Outcomes measures were preservation of preoperative mydriasis, phacoemulsification time and energy, operative time, corneal clarity, endothelial cell counts, postoperative inflammation, intraoperative and postoperative discomfort, complications, and incidence of clinically significant cystoid macular edema (CME)., Results: Maintenance of pupil size with 3-day ketorolac dosing was significantly better than with 1-day dosing (P<.01), which was significantly better than with 1-hour or placebo dosing (P<.01). Both 3-day and 1-day dosing were superior to 1-hour or placebo dosing. No patient receiving ketorolac 0.4% for 1 or 3 days developed CME compared with 12% of patients in the control (placebo) group and 4% in the 1-hour group. Three-day and 1-day dosing of ketorolac reduced surgical time, phacoemulsification time and energy, and endothelial cell loss and improved visual acuity in the immediate postoperative period compared with 1-hour predosing and the placebo (P<.05)., Conclusion: The preoperative use of ketorolac tromethamine 0.4% for 3 days followed by 1-day of predosing provided optimum efficacy and superior outcomes relative to 1-hour pretreatment and a placebo.

- Abstract
Purpose: To investigate the efficacy of the fourth-generation fluoroquinolone, gatifloxacin 0.3%, compared to ciprofloxacin 0.3%, in preventing Streptococcus pneumoniae keratitis in a rabbit laser in situ keratomileusis (LASIK) model., Methods: Twelve albino rabbits had bilateral lamellar flaps created. Group A (eight eyes) was given gatifloxacin 0.3%; group B (eight eyes) was given ciprofloxacin 0.3%; and group C (eight eyes) served as the controls. Groups A and B received one drop of antibiotic 20 minutes before the creation of the lamellar flap, at the conclusion of flap formation, and four times per day for 3 days. All corneas were inoculated with 0.1 mL of 4 x 10 organisms/mL of S. pneumoniae immediately after flap formation. On day 3, all corneas were examined and cultured., Results: Group A (gatifloxacin) had no infiltrates and three areas of 1-mm central corneal haze. On day 3, one of eight corneas had a positive culture. Group B (ciprofloxacin) had seven infiltrates, including one perforation, and six of eight corneas had positive cultures. Group C (control) had eight corneal infiltrates, and all eight corneas had positive cultures. The data show a statistically significant difference between gatifloxacin and ciprofloxacin and gatifloxacin and control for mean infiltrate size and mean culture scores., Conclusions: The fourth-generation fluoroquinolone, topical gatifloxacin 0.3%, is superior to topical ciprofloxacin 0.3% for prophylaxis against a clinical isolate of S. pneumoniae in a rabbit LASIK model.

- Abstract
Purpose: To study the correlation between severity of clinical systemic symptoms and the degree of stromal haze and visibility of epithelial and stromal nerves on scanning slit confocal microscopy examination in Meretoja syndrome., Methods: Three patients with Meretoja syndrome were examined by slit-lamp microscopy and scanning slit confocal microscopy., Results: Increased symptoms and abnormal slit-lamp findings correlated positively with confocal microscopic stromal haze intensity and inversely with visibility of epithelial and stromal nerves on confocal examination. A prominent deposit, presumably amyloid, was observed contiguous to a stromal nerve of an affected cornea. In a severely affected cornea, no stromal or epithelial nerves were seen., Conclusion: The results of this study suggest that Meretoja syndrome causes corneal nerve damage and eventual degeneration that correlates with the degree of clinical involvement.

- Abstract
1. The cause of blepharitis is still a mystery, and, consequently, a cure for this condition does not exist. Patients suffering from blepharitis must be made to understand this and that it is a manageable condition. 2. EyeScrub provides cleansing of the eyelashes and lid margins. Good lid hygiene is crucial to controlling blepharitis. Performed daily in tandem with other simple procedures, EyeScrub removes the oily buildup under the lashes and in the lid margins which causes the eyes to become irritated and encrusted. 3. The application of EyeScrub is simple and does not damage the ocular surface. Lint-free pads allow the patient to feel exactly where the pad is contacting the eye area so that the solution can be applied effectively and harmlessly.

- Abstract
Increasing evidence indicates that long-term use of topically administered medications can induce changes in the conjunctiva and ocular surface. We used the technique of conjunctival impression cytology to evaluate the conjunctival changes that develop with long-term use of topically administered antiglaucoma medications. Patients with glaucoma who were on a stable regimen of one, two, or three topically administered medications were recruited for study; glaucoma suspects who were not using topically administered medications served as controls. Eyes with clinical or historical evidence of external eye disease or conjunctival surgery were excluded. Impression cytology specimens, collected from the bulbar and palpebral conjunctiva, were coded and subsequently graded by a masked observer. We examined specimens from 72 eyes by using this technique. Aggregate scores for the bulbar conjunctiva were compiled, using a previously described grading system with a range of 0 (normal) to 3 (diffuse, severe metaplasia). The results show statistically significant degrees of conjunctival metaplasia associated with the number of glaucoma medications used. These results suggest that the long-term use of antiglaucoma medications induces changes in the conjunctival surface. These changes may be related to the medications themselves, the preservatives in the commercial preparations, or the duration of topical treatment. The clinical relevance of these changes remains unknown.

- Abstract
We reviewed 100 consecutive ophthalmology consultations performed on inpatients at a large teaching hospital to help identify areas that may require greater emphasis in the medical school and housestaff curriculum. Nonophthalmologists rarely record visual acuities or perform dilated fundus examinations. If visual acuity determination were more consistently made a part of routine physical examinations, it is possible that more pathology would be detected and non-productive consultations could be minimized. We plan to emphasize these observations in our school's curriculum more than in the past.

- Abstract
Vitamin A deficiency causes blindness, increased systemic morbidity, and increased mortality among preschool children in many developing nations. Presently, there is no simple, reliable test to detect early, physiologically significant vitamin A deficiency. We used conjunctival impression cytology results to evaluate children with early xerophthalmia before treatment and again three to eight weeks later. Subsequently, we modified our technique. We then compared children with early xerophthalmia to normal children. Conjunctival impressions from children with xerophthalmia all showed complete loss of goblet cells and the appearance of enlarged, partially keratinized epithelial cells. Conjunctival impressions from treated and normal children showed normal goblet cells and sheets of small epithelial cells. These results suggest impression cytology may represent the first simple, objective, diagnostic test for the detection of early vitamin A deficiency.

- Abstract
Impression cytology is a simple technique for detecting vitamin A deficiency. Methods of specimen collection, fixation, and staining are amenable to use in developing countries. Routine use of the technique requires good interobserver agreement. We compared the impression cytology results of 206 patient examinations analyzed by an experienced observer with those obtained by a newly trained observer. Percent agreement measured 96% (197/206) with a kappa of 0.90, indicating excellent agreement. Further improvement in interobserver agreement may be obtainable by simplification of the staining process to highlight the presence or absence of goblet cells, and by simplification of the staging criteria.

- Abstract
Vitamin A (retinol) deficiency causes blindness, increased morbidity, and mortality among preschool children in many developing nations. Previous studies suggest that impression cytology may represent the first simple, reliable test to detect mild xerophthalmia in young children. We used impression cytology to evaluate and follow up 75 Indonesian preschool children with mild xerophthalmia and an equal number of age-matched, clinically normal neighborhood controls. Results of impression cytology, which were closely correlated with baseline serum vitamin A levels, documented histologic improvement following treatment with vitamin A. Furthermore, results of impression cytology, where abnormal, improved to normal following vitamin A treatment in a significant percentage (23%) of otherwise clinically normal children. Impression cytology appears to detect clinical and physiologically significant preclinical vitamin A deficiency.

- Abstract
Respiratory arrest is a serious complication of retrobulbar anesthesia. We have prospectively followed 3123 retrobulbar injections to determine the incidence of respiratory arrest and identify possible risk factors. Injections contained either 2% or 4% lidocaine with 0.75% bupivacaine (Marcaine) in a 50:50 mixture by volume (total 10 cc.) to which a 1 ml ampule of hyaluronidase (150 NF units) was added. Use of 4% lidocaine gave a significantly higher incidence of respiratory arrest than 2% lidocaine (0.79% vs. 0.09%; P = 0.003, Fisher's exact test). Serum levels of lidocaine and bupivacaine of patients who arrested were not elevated significantly compared to 20 control patients. All levels were well below accepted levels of toxicity. Thus, 4% lidocaine increases the risk of respiratory arrest. These results suggest the mechanism is not direct intravascular or central nervous system injection.
