    ABSTRACT: Despite the fact that cosmetic products undergo rigorous testing to ensure they are safe for human use, some users report mild discomfort following their application. The cutaneous changes, such as allergic dermatitis, are well reported, but the ocular changes associated with eye cosmetic use are less so. Some pigmented cosmetic products may accumulate within the lacrimal system and conjunctivae over many years of use, but immediate reports of eye discomfort after application are most common. Changes to the tear film and its stability may occur shortly after application, and contact lens wearers can also be affected by lens spoliation from cosmetic products. Additionally, creams used in the prevention of skin aging are often applied around the eyes, and retinoids present in these formulations can have negative effects on meibomian gland function and may be a contributing factor to dry eye disease. The aim of this review is to summarize current knowledge regarding the impact of cosmetic products on the eye, ocular surface, and tear film.

    ABSTRACT: Objectives: To analyze the dynamic relationship between ocular geometrical structure and high-order aberrations (HOAs) in teal-time during accommodation of human eye. Methods: A custom-built spectral domain optical coherence tomography (OCT) system with high-speed and ultra-long scan depth was used to image the anterior segment, whereas a Shack-Hartmann wavefront sensor was used to detect the whole-eye aberration. A Badal optometer with switched visual targets was integrated with this system to induce 0 and 3.00 D accommodative stimuli. Three young adult subjects were measured and the structural parameters of anterior segment were measured from OCT images and accommodative response and HOAs were calculated and exponentially fitted in real time during the accommodation. Results: The dynamic process from nonaccommodation to 3.00 D accommodation results in reduced pupil diameter, shallower anterior chamber depth, and increased crystalline lens thickness. After an accommodative active time, the RMS of the HOAs changes sharply when an accommodative stimulus is introduced and then tends to be stable. The accommodative response time and velocity are characterized by fitted parameters. The individual differences of changing in HOAs between subjects can be explained by the different sign and changing tendency of certain terms of aberration coefficients in form of Zernike polynomials during the accommodation. Conclusions: Based on the integrated ocular measurement platform including OCT system and wavefront sensor, our research demonstrated how the morphology of the human anterior segment affect the aberration in real time during accommodation. The dynamic relationship between them helps us to deeply understand the mechanism of accommodation.

    ABSTRACT: Purpose: To report a case of wavelike interface opacities in a patient who underwent Descemet-stripping automated endothelial keratoplasty (DSAEK) and was managed conservatively over the course of 7 years. Methods: A 65-year-old woman underwent DSAEK for pseudophakic bullous keratopathy. Textural wavelike opacities were noted in the graft-host interface 6 days postoperatively without evidence of anterior segment inflammation. The patient's vision was also initially limited by the presence of cystoid macular edema (CME). Six months postoperatively, CME had resolved but the patient's vision failed to improve better than 20/80 because of the persistent dense interface opacities. The patient refused to undergo graft exchange despite a suboptimal visual result and she therefore was observed over time. Results: The interface opacities started to regress and her visual acuity improved to 20/30 by 9 months postoperatively. The opacities became gradually less prominent over the next few years, and at 7 years postoperatively, her best-corrected vision was 20/25. Conclusion: In this case, observation of this post-DSAEK complication rather than surgical intervention resulted in a favorable long-term visual outcome.

    ABSTRACT: Objectives: To noninvasively investigate regional differences in tear film stability and meibomian glands in patients with aqueous-deficient dry eye. Methods: Forty-nine dry eyes and 31 normal eyes were analyzed. A corneal topographer with a tear film scanning function was used for noninvasive tear film break-up time (NI-TFBUT) measurements and meibomian gland observations. The NI-TFBUT values and location of the first tear film break-up point were recorded in four quadrants. Meibomian gland loss was graded for each eyelid using meiboscores. Lid margin abnormality was scored from zero to four according to the number of existing abnormalities. The NI-TFBUT values and meiboscores were compared between two groups, and regional differences in NI-TFBUT values and meiboscores were analyzed. Also, the correlation between the NI-TFBUT and ocular surface examination results were investigated. Results: The NI-TFBUT values and meiboscores were significantly lower and higher, respectively, for the dry eye group than for the normal group. In the dry eye group, the occurrence rate for first tear film break-up was the highest in the inferior nasal quadrant, and the mean meiboscore was significantly higher for the upper eyelids than for the lower eyelids. The NI-TFBUT and lid margin abnormality scores showed a weak negative correlation, and the NI-TFBUT values and meiboscores showed no correlation. Conclusions: Compared to normal eyes, aqueous-deficient dry eyes show significant regional differences in tear film stability and meibomian glands. Considering these regional differences, the overall observation of the ocular surface, including both upper and lower eyelids, will aid clinicians in understanding this condition better.

    ABSTRACT: Dry eye disease affects a substantial segment of the word population with increasing frequency. It is a multifactorial disease of the ocular surface and tear film, which causes ocular discomfort, visual disturbances, and tear instability with potential damage to the cornea and conjunctiva. Because of its multifactorial etiology, the use of different pharmacological treatment for dry eye treatment has been proposed, which include anti-inflammatory molecules, lubricants or comfort agents, and secretagogues. However, in some cases these pharmacological approaches only relieve symptoms temporarily, and consequently, eye care professionals continue to have difficulties managing dry eye. To improve pharmacological therapy that allows a more efficient and long-term action, effective ocular drug delivery of the currently available drugs for dry eye treatment is required. Contact lenses are emerging as alternative ophthalmic drugs delivery systems that provide an increased residence time of the drug at the eye, thus leading to enhanced bioavailability and more convenient and efficacious therapy. In this article, we reviewed the different techniques used to prepare contact lens-based drug delivery systems and focused on articles that describe the delivery of compounds for dry eye treatment through contact lenses.

    ABSTRACT: Objectives: To determine the frequency, clinical characteristics, and visual outcomes of patients who present with high or normal intraocular pressure (IOP) and open globe injuries. Design: Retrospective chart review. Setting: University of Maryland Medical Center, a level 1 trauma center. Patient or study population: All cases of open globe injury presenting to The University of Maryland Medical Center from July 2005 to January 2014. Observation: Demographics, initial physical examination, computed tomography findings, IOP of the affected and unaffected eyes, and follow-up evaluations. Main outcome measures: (1) IOP 10 mm Hg or greater and (2) visual acuity. Results: Of 132 eyes presenting with open globe injury, IOP was recorded in 38 (28%). Mean IOP for the affected and unaffected eyes was 14±10.3 mm Hg and 16.6±4.1 mm Hg, respectively. Twenty-three (59.4%) eyes had IOP greater than 10 mm Hg. Six eyes (16.2%) had IOP greater than 21 mm Hg. Using bivariate analysis, IOP greater than 10 mm Hg was associated with posterior open globe injury (P=0.01), posterior hemorrhage (P=0.04), and intraconal retrobulbar hemorrhage (P=0.05). Adjusting for age, sex, and race, IOP greater than 10 mm Hg was associated with the presence of posterior open globe injury on clinical examination (P=0.04). Higher presenting IOP was found to predict light perception or worse vision (P=0.01). Multivariate analysis showed that poor presenting vision was the best predictor of poor final vision (P<0.01). Conclusions: High IOP does not exclude open globe injury. It is a frequent finding in patients with open globe injuries and may be associated with posterior injury and poor visual prognosis.

    ABSTRACT: Purpose: To determine the distribution of the anterior chamber angle (ACA) and anterior chamber volume (ACV) in an Iranian population of 40- to 64-year-old people using the Pentacam. Methods: In this cross-sectional study, multistage sampling was used to select 300 clusters, including 6,311 individuals from the city of Shahroud. All selected participants underwent examinations in one place. Optometric examinations, including measurement of visual acuity and refraction, and ophthalmologic examinations, including slit-lamp examination, were performed for all participants. Moreover, all patients underwent imaging with the Pentacam. Results: The mean ACA and ACV was 34.3° (95% confidence interval [CI]: 34.1°-34.5°) and 139 μL (95% CI: 137.7-140.3), respectively. In a multiple linear regression model, the ACA was inversely correlated with age (coefficient=-0.08), lens thickness (coefficient=-1.38), corneal diameter (coefficient=-0.36), and corneal curvature (coefficient=-1.43), and directly correlated with the anterior chamber depth (ACD) (coefficient=6.59). In another model, ACV was inversely correlated with age (coefficient=-0.37), central corneal thickness (coefficient=-0.04), and spherical equivalent (coefficient=-1.15), and directly correlated with the ACD (coefficient=85.67), lens thickness (coefficient=14.15), corneal diameter (coefficient=4.80), corneal curvature (coefficient=18.43), ACA (coefficient=0.65), and intraocular pressure (coefficient=0.23). Conclusion: The findings of this study could be used as a reference for diagnosis and treatment in Iran and the Middle East region. Increase in age and decrease in the ACD were important factors associated with decreased ACA and ACV, although the correlation of other biometric components was also evaluated. Some of these components, such as the corneal curvature and lens thickness, had a significant relationship with these two variables.

    ABSTRACT: The most effective strategy to reduce myopia-related complications is to prevent myopia progression during childhood. This review article examines the latest published evidence on the use of atropine in childhood myopia control and discusses practical aspects of applying the findings to clinical practice. Future directions including possible forms of combination therapy are examined. A literature search with a focus on randomized controlled trials (RCTs) and meta-analyses on the subject was conducted. Observational studies with control groups were also reviewed to discuss issues regarding feasibility of using atropine for myopia control in clinical practice. Five RCTs and 2 meta-analyses were found. The studies all found beneficial effects of atropine in myopia control, as well as a clear but perhaps clinically insignificant dose-response relationship between atropine and myopia progression rates. Available evidence however is focused on predominantly Chinese populations, and there is a current lack of guidance on timing of therapy initiation, duration of therapy, and treatment cessation. For future directions, combining atropine with other forms of myopia control would be worth considering. Atropine is robust option for childhood myopia control. Further evidence including RCTs in different populations as well as the upcoming 5-year atropine for the treatment of myopia 2 trial results will provide much needed answers for wider acceptance of its use.

    ABSTRACT: To compare the efficacy of diclofenac sodium (DS) 0.1% and fluorometholone (FL) 0.1% in patients with perennial allergic conjunctivitis. Fluorometholone 0.1% or DS 0.1% eye drops were topically administrated 4 times daily for 4 weeks in patients with perennial allergic conjunctivitis. Assessment was conducted with a 4-point rating scale (0=none, 1=mild, 2=moderate, and 3=severe) for 4 signs and 5 symptoms. Two hundred sixty-one patients were recruited. The demographics and baseline skin prick scores between both groups were comparable. Mean baseline scores in DS and FL group were 6.77±2.24 and 6.34±2.10, respectively. The scores rapidly decreased to 3.28±1.47 and 2.69±1.44 on day 7. Diclofenac sodium expressed a slower effect compared with FL within the first 3 days of treatment (P=0.01). The efficacy of topical FL and DS was comparable for the management of cases with perennial allergic conjunctivitis. However, FL led to a more rapid alleviation of signs and symptoms as compared with DS in early days after the initiation of treatment.

    ABSTRACT: The purposes of this study were to determine whether the contact lens solution RevitaLens Ocutec (containing the antimicrobial agents alexidine and polyquaternium-1) would inhibit Fusarium organisms when heated in ReNu plastic bottles; whether alexidine would inhibit Fusarium organisms when heated in non-ReNu plastic bottles; and whether an alexidine-neutralizing compound leaches from heated ReNu bottles. RevitaLens and an alexidine solution (0.00045%), previously stored in ReNu bottles at room temperature (RT) and 56°C, were incubated with 7 different Fusarium organisms. The alexidine solution was similarly stored in seven non-ReNu plastic bottles and incubated with these same organisms. To determine if an alexidine-neutralizing compound might be leaching from heated ReNu bottles, phosphate-buffered saline (PBS) was incubated at RT and 56°C in ReNu bottles, combined with alexidine, and then tested for anti-Fusarium capability. After being heated in ReNu bottles, RevitaLens retained its anti-Fusarium capability, whereas the alexidine solution did not. The alexidine solution heated in seven non-ReNu plastic bottles retained its anti-Fusarium capability. The alexidine solution retained its anti-Fusarium capability when incubated with a PBS solution that had been heated in ReNu bottles, indicating, microbiologically, that an alexidine-neutralizing compound did not leach from the heated ReNu bottle. Alexidine uniquely fails to inhibit Fusarium organisms when heated in a plastic ReNu bottle, but not in seven other plastic bottles, whereas the anti-Fusarium capability of RevitaLens (containing the antimicrobial agents alexidine and polyquaternium-1) is unaffected by heating in a ReNu bottle. There does not seem to be an alexidine-neutralizing compound leaching from heated ReNu bottles. An interaction between alexidine and its heated ReNu bottle may have been a critical factor in the worldwide ReNu with MoistureLoc-related Fusarium keratitis event of 2004 to 2006.

    ABSTRACT: This study investigated changes in selected tear cytokine concentrations (IL-1β, IL-1Ra, IL-6, IL-10, IL-12 (p70), and TNF-α) after a 1-week washout from soft contact lens wear (CLW), and the repeatability of cytokine measurements using custom multiplex assays. A total of 10 subjects completed this 6-visit (immediately following contact lens removal, and after 1, 2, 3, 4, and 7 [±1] days without CLW) pilot study. Approximately 20 to 30 μL of pooled basal tears were collected from both eyes at each visit. Two custom multiplex assays were used by two operators to quantify the concentration of tear cytokines. Tear samples from subjects 1 to 6 were analyzed using the first kit by operator 1. Tear samples from subject 7 to 10 plus additional tear samples from subjects 1 to 5, which were used to determine the between-kit per operator repeatability, were analyzed using the second kit by operator 2. Linear mixed models were used to determine changes in tear cytokine concentrations over time. Between-kit per operator and within-kit per operator repeatabilities were assessed using the Bland and Altman analysis. There were no significant changes in tear cytokine concentrations over a 1-week washout of CLW. More than 99% of the tear samples had detectable levels of cytokines using custom multiplex assays. Within-kit per operator repeatability was good, but between-kit per operator repeatability was poor; likely due to protein degradation, differences in operator experience, and operating procedures. A washout period may not be necessary when evaluating changes in tear cytokines with new contact lenses or lens care products. A well-trained operator using standardized operating procedures can produce repeatable measurements using custom multiplex assays.

    ABSTRACT: The present study examined the long-term (3 years) effects of a single (12 min) thermal pulsation system (TPS) treatment on symptomatic patients with evaporative dry eye disease (DED) secondary to meibomian gland dysfunction (MGD). In this prospective, cohort, observational, single-center study design, signs (meibomian gland secretion [MGS] scores and tear film breakup time [TBUT]) and symptoms (Ocular Surface Disease Index [OSDI] and Standard Patient Evaluation of Eye Dryness [SPEED] questionnaires) were determined in 20 patients (40 eyes) with MGD and dry eye symptoms at baseline (BL), 1 month, and 3 years post-TPS treatment using LipiFlow. Meibomian gland secretion scores increased from BL (4.5±0.8) to 1 month (12.0±1.1, P≤0.001). Improvement persisted at 3 years (18.4±1.4) relative to BL (P≤0.001). Meibomian gland secretion scores in all regions of the lower eyelid were improved over BL at 1 month (nasal [P≤0.001], central [P≤0.001], temporal [P≤0.01]) and 3 years (nasal [P≤0.001], central [P≤0.001], temporal [P≤0.001]). TBUT increased from BL (4.1±0.4) to 1 month (7.9±1.4, P≤0.05) but was not significantly different than BL at 3 years (4.5±0.6, P>0.05). The OSDI scores decreased from BL (26.0±4.6) to 1 month (14.7±4.3, P≤0.001) but returned to BL levels at 3 years (22.5±5.4, P>0.05). The SPEED scores decreased from BL (13.4±1.0) to 1 month (6.5±1.3, P≤0.001), and this improvement persisted at 3 years (9.5±1.6, P≤0.001). Thermal pulsation may be a uniquely efficacious treatment option for DED secondary to MGD in that a single 12-min procedure is associated with significant improvement in MGS and SPEED scores for up to 3 years.

    ABSTRACT: Psoriasis is a common chronic inflammatory skin disease. Ocular manifestations, which occur in 10% to 20% of cases of psoriasis, are usually bilateral and often present during an exacerbation of the psoriasis. Serious corneal involvement is rare but can be devastating. Two cases of sterile corneal infiltrates secondary to an exacerbation of psoriasis are presented. Treatment involved the use of 0.02% topical tacrolimus ointment, which resulted in resolution of the symptoms and infiltrates. Topical tacrolimus may be considered as an alternative treatment option to corticosteroids in sterile corneal infiltrates.

    ABSTRACT: To determine the characteristics of infectious keratitis caused by Kocuria spp. Retrospective case series. Information included demographic data, medical history, risk factors associated with infectious keratitis, clinical characteristics, microbiological results and drug sensitivity, clinical course, management, and visual outcomes. Eight patients were included (7 females and 1 male; mean age, 66.2 years; age range, 42-84 years). All patients presented risk factors for infectious complications, such as filamentous keratitis, dry eye, blepharitis, and persistent corneal edema. In all cases, ulcers were classified as severe. The infection resolved with medical treatment in one eye only. One case was treated with amniotic membrane graft. Two patients required keratoplasty (lamellar and penetrating), and one case needed sclerokeratoplasty. In three cases, the keratitis was severe enough to require evisceration. The final visual acuity ranged from 20/25 to no light perception. Bacterial keratitis by Kocuria spp. is a rare infection that may have an unexpected clinical course and possible serious outcomes. This pathogen should be considered in patients with unusual clinical course. Local or systemic immune compromise in the genesis of the disease must also be taken into account, and ophthalmologists should be more suspicious in this vulnerable group of patients.

    ABSTRACT: In our study, we aimed to investigate the correlation of handheld infrared skin thermometer and videothermography device for the measurement of corneal temperature. Forty healthy individuals (80 eyes) were enrolled to the study. Participants underwent a detailed ophthalmologic examination and medical history review for excluding any ocular and systemic diseases. The measurements of the central corneal temperature were performed in a room having constant temperature, humidity, and brightness levels. To avoid any variability, all the temperature measurements were performed in the same examination room by a single examiner. The temperature was measured with a handheld infrared skin thermometer (MEDISANA, FTN) from the corneal surface. The same instrument was also used to measure the subjects' body temperature. Moreover, the subjects underwent the corneal temperature measurement by a noncontact videothermography device (Optris PI 450; Optris GmbH). The male to female ratio was 19:21 among the subjects. The mean age was 25.1±4.7 years. The mean body temperature was 36.93±0.33°C. The mean corneal temperatures measured by the handheld infrared skin thermometer and the ocular videothermography device were 36.94±0.28°C and 35.61±0.61°C, respectively (P<0.01). The mean temperature difference was 1.34±0.57°C, with a 95% confidence interval. There was a moderate correlation between the corneal temperatures measured by the 2 devices in the right, the left eyes, and both eyes, respectively (P=0.450, 0.539, 0.490). Handheld infrared skin thermometers can be used for the evaluation of the corneal temperature. These devices may provide a simple, practical, and cheaper way to detect the corneal temperature, and the widely performed corneal temperature measurements may afford us to understand the temperature variability in numerous ocular conditions in a better way.
