ABSTRACT
Purpose@#We sought to investigate the temporal changes of eyelid height after phenylephrine instillation in Korean patients with and without ptosis to determine the time points of the first and maximum reactions. @*Methods@#The phenylephrine test was performed on 16 eyes of 12 ptotic patients (group I) and 24 eyes of 12 normal control subjects (group II) in our hospital between September 2017 and March 2018. One drop of 2.5% phenylephrine was instilled and the marginal reflex distance 1 (MRD1) was measured at 15 seconds before instillation and the following time points after instillation: at 15-second intervals for the initial 5 minutes and at 5-minute intervals until a total of 20 minutes was reached (i.e., at 10, 15, and 20 minutes). @*Results@#In group I patients, the first reaction appeared at 5 minutes (p = 0.034), while the maximum eyelid height after the first reaction was reached at 15 minutes (p = 0.025) and was maintained until 20 minutes. In group II subjects, the first reaction appeared at 5 minutes (p = 0.034), while the maximum eyelid height was reached at 10 minutes (p = 0.015) and was maintained until 20 minutes. There was no significant difference in the response of eyelid height based on time (p = 0.122) between the two groups. @*Conclusions@#Our analysis of phenylephrine test results in Korean ptotic patients revealed a significant increase occurred in the eyelid height after 5 minutes; meanwhile, the maximum eyelid height was reached at 15 minutes and was maintained until 20 minutes after instillation.
ABSTRACT
PURPOSE@#To investigate the relationship between peripheral retinal degeneration including retinal tear and character of floater and flash in patients with symptoms.@*METHODS@#A retrospective review of 56 patients who visited Dong-A University Hospital with the symptoms of vitreous floaters and flash between July 2017 and March 2018 was performed using medical records. All patients completed a questionnaire detailing their symptoms include duration of symptoms, characters, floaters with flash and associated another visual symptom (e.g., headache, whiteout) had been performed full ophthalmic examination.@*RESULTS@#A total of 56 eyes were included in this study, including 22 eyes (39.3%) of retinal breaks and peripheral retinal degeneration and 34 eyes (60.7%) of no peripheral retinal degeneration. Univariated analysis showed that the onset of symptoms within 1 week, multiple floaters particularly for the number from 2 to 5, and existence of posterior vitreous detachment are meaningful factor. Laser photocoagulation was performed in patients with peripheral retinal degeneration including retinal tears requiring treatment. No additional breaks were observed in all patients during the 6-month follow-up.@*CONCLUSIONS@#Patients with floaters and flash should be thoroughly asked with regard to the onset and number of floaters, and if the onset of symptom is within one week or patients feel multiple floaters, thorough peripheral fundus examination to find peripheral retinal degeneration including retinal tears should be needed.
ABSTRACT
PURPOSE: To evaluate the incidence and risk factors for ocular hypertension (OHT) in traumatic hyphema within 7 days after trauma. METHODS: A retrospective case series study of 265 traumatic hyphema inpatients from 2010–2016. OHT was defined as intraocular pressure (IOP) that exceeded 21 mmHg using two consecutive measurements by a Goldmann applanation tonometer within 7 days after trauma. The subjects were divided into two groups (OHT group and non-OHT group). Age, sex, best-corrected visual acuity (BCVA), IOP, hyphema grade, presence of systemic disease, and past history of glaucoma were compared between the two groups. RESULTS: Of the 265 patients, 95 (35.8%) developed OHT after traumatic hyphema. Of those 95 patients, 70 (73.7%) developed OHT within 1 day after trauma; 18 (18.9%) developed OHT 2–3 days after trauma; and 7 (7.4%) developed OHT 4–7 days after trauma. Compared to the non-OHT group, the OHT group had a lower visual acuity (p = 0.018) and higher IOP (p < 0.001). In addition. if the hyphema grade was higher the incidence of OHT was significantly higher (p = 0.017). Using multivariate logistic regression analysis, the BCVA (p = 0.045) and hyphema grade (p = 0.006) were associated with the incidence of OHT in traumatic hyphema within 7 days after trauma. CONCLUSIONS: The incidence of OHT in traumatic hyphema within 7 days after trauma was 35.8%. The BCVA and hyphema grade were associated with the incidence of OHT within 7 days after trauma.
