  • Purpose : The purpose of this study was to investigate the temperature changes of the ocular surface before and after cataract surgery using thermography of a thermal imaging camera. Methods : The study included 75 patients (75 eyes) aged from 50 to 79 years who underwent cataract surgery. In the past, those who underwent corneal-related surgery, wearing contact lens, disorder of tear secretion and taking medication for systemic disease were excluded from this study. The temperature changes of the eyeball surface were measured using a thermal imager (Cox CX series, Answer, Korea) following Tear Break Up Time (TBUT) test, Mcmonnies questionnaire and Schirmer's Test in real time, Results : While the temperature of preoperative ocular surface was $35.20{\pm}0.54^{\circ}C$ and that of postoperative temperature was $35.30{\pm}0.53^{\circ}C$, the difference was not significant. The temperature changes in the ocular surface were statistically significant at $-0.12{\pm}0.08{\Delta}$ ($^{\circ}C/sec$) before the surgery and $-0.18{\pm}0.07{\Delta}$ ($^{\circ}C/sec$) after the surgery. In comparison of the age groups, it was shown that the changes in the surface temperature before the surgery were from $-0.19{\pm}0.05{\Delta}$ ($^{\circ}C/sec$) to $-0.14{\pm}0.09{\Delta}$ ($^{\circ}C/sec$) in the 50s group, and from $-0.12{\pm}0.08{\Delta}$ ($^{\circ}C/sec$) to $-0.15{\pm}0.07{\Delta}$ ($^{\circ}C/sec$) in 60s group, and $-0.18{\pm}0.07{\Delta}$ ($^{\circ}C$) to $-0.12{\pm}0.08{\Delta}/sec$) in the 70s group, showing significant changes in the ocular surface temperature at all ages. Conclusion : Following the cataract surgery, all the indicators of dry eye syndrome were decreased, and eye surface temperature changes were significant. The thermography technique of the ocular surface would be expected to be useful for the evaluation of various dry eye syndromes because it is easy to evaluate dry eye syndrome noninvasively and can be quantified.

  • Purpose: The purpose of this research was to see how wearing either a SCL or a C-SCL effected the dryness of a person's eye depending on how long they wear either type of lens. Methods: This study was carried out on 52 subjects (104 eyes) who were all in their twenties and had previously experienced wearing contact lenses. All of these subjects were required to wear either a SCL or a C-SCL, which were made out of the same material, for three months. Contents such as the McMonnies Questionnaire survey, the blinking rate per min. and the Noninvasive tear break-up time test (NIBUT) were later conducted on the subjects for this study. Results: According to the results of the McMonnies Questionnaire, it was concluded that the longer the subject wore the SCL and C-SCL, the value of the measurements gradually increased. On the other hand, the results from the NIBUT concluded that the longer the subject wore the SCL, the value of the measurements eventually decreased. However, according to the measurements of the blink rate test, it was concluded that neither results had a significant change. Conclusions: It was concluded that long-term wearing of SCL and C-SCL could be the cause of the induction and progression of dry eyes.

  • Dry eye symptoms can occur by various environmental exposure. This study aimed to investigate the relationship between eye symptom especially dry eye and sunblocks. Study subjects were total 30 (28 male, 2 female) and NIBUT, McMonnies dry eye questionnaire, subjective questionnaire were performed. NIBUT after rubbing sunblocks was decreased compared to that of not-rubbing. Sunblocks C showed the largest difference of NIBUT value and was chosen most uncomfortable sunblocks in subjective questionnaire. Half of the subjects (15) felt eyes discomfort after rubbing sunblocks and showed larger McMonnies dry eye questionnaire score than other subjects. The same result was founded about dry eye suspect criterion. Both showed borderline significant relation(p=0.049, p=0.051). This study suggested that sunblock could cause damage to the eyes and related to dry eye when rubbing sunblock around eyes. Because digital environmental factors could affect stimulus and modify the eyes, a convergence study will be required for additional research.

  • Purpose: To compare the success rates between silicone tube intubation using a lacrimal endoscope and using a conventional nasal endoscope alone in adult patients suffering from epiphora. Methods: We conducted a retrospective chart review of 80 eyes of 55 patients who underwent silicone tube intubation from January 2014 to June 2017. Patients were preoperatively diagnosed with syringing and dacryocystography. The silicone tube was removed 3 months after surgery and success rates were evaluated at 4 and 12 months. Success rates were analyzed by dividing the patients into two groups, according to lacrimal endoscope use. Results: A lacrimal endoscope was used in 40 eyes. In the group using a lacrimal endoscope, preoperative diagnoses were partial obstruction in 26 eyes and complete obstruction in 14 eyes. In the group without lacrimal endoscope use, preoperative diagnoses were partial obstruction in 35 eyes and complete obstruction in 5 eyes (p = 0.018). The success rates at 4 and 12 months after surgery in the two groups (with and without lacrimal endoscope use) were 87.5% and 80.0% and 72.0% and 62.1% (p = 0.546 and p = 0.565), respectively. The success rates of patients with partial obstruction in the two groups were 92.3% and 82.9% at 4 months and 71.4% and 69.2% at 12 months (p = 0.448 and p = 1.000), respectively. The success rates of patients with complete obstruction in the two groups were 78.6% and 60.0% at 4 months and 72.7% and 33.3% at 12 months (p = 0.570 and p = 0.505), respectively. Site differences, the degree of obstruction, and lacrimal endoscope use had a significant impact on the success rate at 4 and 12 months (p = 0.001 and p = 0.022, respectively). Conclusions: Although silicone tube intubation using a lacrimal endoscope cannot guarantee a significant success rate, it is possible to observe the anatomical structure of the nasolacrimal pathway in real time, such that the appropriate diagnosis and treatment can be performed simultaneously. Because patients diagnosed as having a complete obstruction had a good success rate, we can extend indication of silicone tube intubation as a less invasive approach.

  • This study was performed to compare the relationship between contact lens wearer and dry-eye patient. In this study, TBUT, SIT, TTT, Rose bengal staining and McMonnies dry eye symptom questionnaire were performed as a baseline. With the base data, the subjects were classified to 3 groups : 3S patients who have dry eye signs and symptoms, 38 patients who are wearing soft contact tenses, 35 subjects who have health eyes and never worn on a contact lenses as control subjects. Contact lens wearers were divided into 3 groups according to the duration of contact lens wear. There were no significant differences in TBUT, STT, TTT, Rose-bengal staining and McMonnies dry eye symptom questionnaire result between contact lens wearer group and dry eye patients group. We suggest that there are similarities in tear function tests between the dry-eye patient and the contact lens wearer.

  • Purpose: To analyze blinking patterns when watching an ultra-high definition (UHD) television and to compare the results between normal eyes and dry eyes. Methods: A total of 59 participants aged from 13 to 69 years were instructed to watch a colorful and dynamic video on a UHD television for 10 minutes. Before and after watching the UHD television, we measured the best corrected visual acuities, autorefraction, tear-break-up-time, degree of corneal erosion and conjunctival hyperemia via slit lamp biomicroscopy. In addition, questionnaires for the evaluation of eye fatigue and symptoms of a dry eye were completed. The definition of dry eye syndrome was that the tear-break-up-time of one of the eyes was less than 5 seconds, conjunctival injection, or marked corneal erosion. The number of blinks and the duration of blinking were both measured and analyzed at the early and late phases of video-watching. Results: After watching the UHD television in the normal eye group, the tear-break-up-time was significantly decreased (p < 0.001) and the degree of corneal erosion was significantly increased (p = 0.023). However, the subjective symptoms of participants were not aggravated (p = 0.080). There were no significant differences in blinking patterns in the dry eye group. On the other hand, in the normal eye group, the mean blinking time was significantly increased (p = 0.030). Conclusions: Watching an UHD television changes the tear-break-up-time, degree of corneal erosion, and blinking pattern in normal eyes, which may increase the risk of dry eye syndrome.

  • Purpose: The aim of this study was to develop a dry eye test method using a paper based microfluidic device that improves inaccuracy caused by using one of current point-of-care dry eye tests such as Shirmer's. Methods: Wax printed hydrophilic chromatography papers were dyed with anthocyanin extracts to detect colorimetric display of liquid samples with varying pH. Fluid distribution rates were measured using artificial tears and human tears directly from 32 subjects. Results: With Shirmer's, fluid distribution rates with small amount of samples (less than $0.5{\mu}l$) were not displayed. However, with paper based microfluidic device, fluid imbibition distances over time were clearly showed. Also clinical results of dry eye from newly developed paper based microfluidic device showed correlation with the results from tear break up time tests. Conclusions: The newly developed paper based microfluidic devices were easy to use and exhibited more accurate clinical results than current dry eye point of care tests such as Shirmer's.

  • The purpose of this study was to evaluate the value of dacryoscintigraphy with Tc-99 m Pertechnetate, which is useful in functional nasolacrimal duct obstruction diagnosis in human medical science, by applying it to normal dogs. Dacryoscintigraphy was performed on six clinically healthy beagle dogs to confirm normal passage of their lacrimal ducts. The scintigraphic images of both lacrimal system were obtained at 5 min, 10 min, and 20 min after Tc-99 m Pertechnetate administration, respectively. If lacrimal duct does not come into view within 20 min, delayed images at 30min, 45min and 60 min were gained. After drawing ROI of left and right canaliculus, lacrimal sac, and nasolacrimal duct acquired after dacryoscintigraphy, we measured each counting rate and developed a counting rate table for each time interval. Of the total of 12 places, 10 (83.3%) showed patency within 20 min, and 11 (91.6%) showed patency within 30 min. In one dog, a functional obstruction of right lacrimal canal was observed. Dacryoscintigraphy could provide useful information about functional and anatomical lacrimal duct obstruction in veterinary medicine as well as in clinical research.
