Long-acting diquafosol ophthalmic solution (DQS-LX) has significant advantages regarding patient adherence owing to the reduced frequency of required eye drops; however, some patients prefer conventional diquafosol ophthalmic solution (DQS) over DQS-LX. Herein, to clarify the characteristics of patients according to their preference for ophthalmic solutions, dry eye (DE) and meibomian gland (MG) findings were retrospectively investigated. This study enrolled 341 patients with DE (mean age, 62.

Methods: This interventional retrospective study included 66 eyes of 66 patients with DED who switched from conventional DQS to DQSLX ophthalmic solution. Tear function assessments (tear film breakup time [BUT], keratoconjunctival vital staining [VS] score), evaluations of DED symptom relief, and a four-item usability questionnaire ("comfort upon instillation," "irritation upon instillation," "eye mucus discharge," "convenience of instillation frequency") assessed using a visual analog scale from 0 (worst) to 10 (best) were administered 4 weeks after switching to DQSLX.
Purpose: To evaluate stress levels extracted from prefrontal electroencephalogram (EEG) signals and investigate their relationship with dry eye symptoms.
Methods: This prospective, cross-sectional, comparative study included 25 eyes of 25 patients with aqueous tear-deficient dry eye (low Schirmer group), 25 eyes of 25 patients with short tear breakup time dry eye (short breakup time group), and 24 eyes of 24 individuals without dry eye. An EEG test, the Japanese version of the Ocular Surface Disease Index (OSDI), and a stress questionnaire were administered.
Purpose: The purpose of this study was to investigate the association between autonomic nerve activity and symptom intensity according to the type of dry eye (DE).
Methods: This prospective, cross-sectional, comparative study included 25 eyes of 25 patients with short tear break-up time DE (sBUTDE; mean age = 57.4 ± 11.
The autonomic nervous system plays a crucial role in the maintenance of homeostasis. Neurogenic inflammation due to decreased stability of tear film may induce changes in autonomic nerve activity, which could be associated with symptom expression.This study aimed to measure biological parameters that represent autonomic nerve activity in dry eye (DE)s caused by tear film dysfunction and investigate their relationship with symptom intensity.

Although many reports have demonstrated positive effects of lid hygiene on demodicosis, some have produced conflicting results. We retrospectively evaluated the effect of lid margin cleansing with a novel lid hygiene detergent, Eye Shampoo, in patients with ocular demodicosis.

Methods: This prospective, cross-sectional, comparative study included 52 eyes of 52 subjects (mean age: 66.8 ± 9.
Purpose: To evaluate transient receptor potential vanilloid 1 (TRPV1)-mediated pain sensitivity in patients with short tear break-up time (TBUT) dry eye (DE) by using the capsaicin stimulus test.
Methods: This prospective cross-sectional comparative study included 22 eyes of 22 patients with short TBUT DE and 11 eyes of 11 non-DE control subjects. Patients were divided into two groups based on response to standard DE treatments: 10 non-responders (intractable DE) and 12 responders (responsive DE).
Purpose: The reported signs and symptoms of dry eye (DE) have been discordant. This study evaluated risk factors of DE-related symptoms and signs to explore their association with patient demographics, focusing on the age factor.
Methods: The study enrolled 704 consecutive patients visiting general eye clinics who complained of ocular discomfort, but had normal vision.
Purpose: This study aimed to prospectively assess tear dynamics in soft contact lens-induced dry eye while wearing and after removing the soft contact lenses.
Materials And Methods: We analyzed 17 right eyes of soft contact lens users at Wada Eye Clinic (11 men, 6 women; mean age: 36.8 ± 8.
The functional visual acuity test which is the average of the visual acuities measured during a specific time frame (standard, 60 seconds) has been used recently to assess the visual function in various conditions. The availability of a shorter version of the functional visual acuity test promises to be patient friendly in that it is a simple screening test performed in a shorter period of time than the standard test. The results of measurements of the FVA test between the 30-second measurement time (short-version FVA test) and the standard 60-second measurement are compared, and the feasibility of the short-version FVA test instead of the standard FVA test is investigated.

Methods: Twelve eyes of 6 subjects were all evaluated just before and after wiping lid margins using 1) tap water alone, 2) Eye Shampoo, 3) Eye Brush, or 4) both products, each during a different week. The results after using both products twice daily for 1 month were also evaluated.
Purpose: To investigate the efficacy of eyelid margin cleansing with lid hygiene detergent in patients with obstructive meibomian gland dysfunction (MGD).
Methods: As a pilot study, we investigated the safety and efficacy of lid hygiene using tap water and/or lid hygiene shampoo in fourteen eyes of 7 normal subjects. All subjects were instructed to cleanse the eyelid margin with tap water and/or lid hygiene shampoo.
Dry eye (DE) causes irregularity of the ocular surface and reduces the quality of vision. An intact, regular tear film is essential for high-quality retinal images; however, visual tasks requiring sustained gazing can disrupt the tear film, eventually degrading visual function. A functional visual acuity (FVA) measurement system has been uniquely developed in Japan to evaluate visual function related to tear stability in patients with DE.

In particular, corneal hypersensitivity may provoke symptoms in short tear break-up time (BUT) DE characterized by tear film instability. We hypothesized that improved tear film stability may alleviate corneal sensitivity in patients with short tear BUT DE.
