Assessment of Tear Film Parameters in Smokers and Subjects with a High Body Mass Index
This study aimed to assess the tear film in smokers, those with a high body mass index (BMI), and healthy subjects using the EASYTEAR view+.
METHODS
Thirty men with a high BMI (>25 kg/m2; 24.4 ± 6.4 years), 30 smokers (25.1 ± 6.1 years), and 30 healthy subjects (22.2 ± 3.5 years) were recruited. Each subject completed the Ocular Surface Disease Index, followed by the assessment of noninvasive tear breakup time, tear meniscus height (TMH), and lipid layer patterns (LLPs).
RESULTS
Significant differences were found in the median TMH scores between smokers and healthy subjects (P = .03) and between subjects w...

Asymmetric Peripheral Refraction Profile in Myopes along the Horizontal Meridian
SIGNIFICANCE
The investigation of peripheral refraction profiles in Indian myopes showed relative peripheral hyperopic refraction in temporal retina and possible dominant role of hyperopic defocus signals from temporal retina in the development of myopia.
PURPOSE
Considering that the peripheral refraction profiles were extensively reported to be associated with the central refractive error and vary among different ethnicities, we investigated the peripheral refraction profiles in Indians.
METHODS
A total of 161 participants aged between 18 and 33 years were included in the study. All of the eligible parti...

Contrast Sensitivity with Center-distance Multifocal Soft Contact Lenses
This study aimed to determine the effect of center-distance multifocal soft contact lenses (MFCLs) on CS under photopic and mesopic conditions in nonpresbyopic patients.
METHODS
Twenty-five myopic, nonpresbyopic adults were fitted binocularly with three lenses: Biofinity single vision contact lens (SVCL), Biofinity Multifocal D +2.50 add, and NaturalVue Multifocal in random order. Contrast sensitivity was measured at distance (4 m) under photopic and mesopic conditions and at near under photopic conditions. Log CS by spatial frequency and area under the log contrast sensitivity function (AULCSF) were analyzed betwee...

Enhanced Depth-of-focus Intraocular Lenses: Latest Wavefront-shaped Optics versus Diffractive Optics
CONCLUSION
The novel wavefront-shaped EDoF IOLs failed to outperform the established diffractive achromatic optics of Symfony EDoF IOL with respect to MTF and qualitative contrast function. These results apply only to the distance viewing condition. Near vision performance will be evaluated in a future study. (Source: Optometry and Vision Science)

Comparison of Two Thermal Pulsation Systems in the Treatment of Meibomian Gland Dysfunction: A Randomized, Multicenter Study
This study aimed to demonstrate noninferiority of SYSTANE iLux compared with LipiFlow at 12 months after single treatment in meibomian gland dysfunction subjects with evaporative dry eye.
METHODS
In this prospective, randomized, multicenter, assessor-masked, parallel-group trial, subjects (N = 236; aged ≥18 years) with meibomian gland score (MGS) of ≤12 in lower eyelids, noninvasive tear breakup time (NITBUT; first breakup) of 16 were randomized (1:1) to receive SYSTANE iLux (n = 119) or LipiFlow (n = 117). Subjects attended a total of eight visits, including screening, treatment, and follow-up visits at 2 weeks...

Case Report: Recurrent Transient Monocular Vision Loss Secondary to Protein C Deficiency
CONCLUSIONS
Transient monocular vision loss is a symptom commonly encountered by eye care providers, which necessitates emergent evaluation to reduce stroke risk if the symptom appears vascular in origin. Testing for hypercoagulable conditions is indicated in patients demonstrating recurrent transient monocular vision loss, even if there is no known personal or family history of venous thromboembolism. Eye care providers need to be aware of this association between hypercoagulable conditions and transient vision loss to aid in prompt diagnosis and treatment with the goal of preventing stroke and permanent vision loss. ...

Case Report: Bilateral Cecocentral Visual Field Defect Secondary to Congenital Optic Disc Pit
CONCLUSIONS
A cecocentral visual field defect, unrelated to maculopathy, is a less common complication of congential optic disc pits that can cause decreased visual function. This case report provides evidence of this bilateral ocular condition and reviews the reported clinical, OCT, and threshold visual field manifestations of the disease. Specifically, spectral-domain OCT ganglion cell analysis seems useful in localizing the visual field defect. (Source: Optometry and Vision Science)

Case Report: Bilateral Valsalva Retinopathy in an Acutely Anemic Patient
CONCLUSIONS
Patient history and the common location of retinal hemorrhages aid in diagnosing Valsalva retinopathy. In this case, the patient had a known history of acute anemia and thrombocytopenia with a recent history of straining. Anemia, among other systemic conditions, can increase the risk of developing retinopathy after a Valsalva maneuver. Although Valsalva retinopathy can occur in healthy patients without underlying conditions, it is important to rule out other conditions that might present with retinal hemorrhage or that may increase the risk of Valsalva retinopathy.

Automatic Screening for Ocular Anomalies Using Fundus Photographs
CONCLUSIONS
The proposed algorithm compares favorably with human performance for normal versus anomalous eye examination classification using fundus photography. Artificial intelligence, which previously targeted a few retinal pathologies, can be used to screen for ocular anomalies comprehensively. (Source: Optometry and Vision Science)
