Eye Drop Chart for Improvement of Topical Eye Drops Administration and Adherence

PURPOSE: To evaluate the efficacy of an eye drop chart and to determine the factors contributing to adherence enhancement using the eye drop chart. METHODS: In this prospective study, enrolled glaucoma patients were educated on the administration of eye drops and use of the eye drop chart. They were required to complete a questionnaire on demographic characteristics and adherence. After 3 months, they completed a second questionnaire on adherence and satisfaction with the use of the eye drop chart. Changes in instillation behavior, relationships between performance scores and demographic characteristics, as well as factors contributing to the improvement of performance scores were analyzed. RESULTS: Forty-seven patients were enrolled in this study. The performance scores were significantly better for those who administered the eye drops by themselves (p = 0.002), those with an annual income > 60 million won (p = 0.036), and patients with at least a college degree (p = 0.002). After using the eye drop chart for 3 months, the average intraocular pressure was significantly reduced (p = 0.041) and the performance score was improved (p = 0.019). The working area (p = 0.009) and eye drop applicator (p = 0.001) were correlated with performance score enhancement. CONCLUSIONS: The eye drop chart was a cost-effective tool for improving the adherence and instillation practices of glaucoma patients. Adherence was improved among patients with more indoor activity, and those who practiced self-instillation. It is expected that the respective conditions of such patients would be more efficiently improved in a clinical setting.

Ocular manifestations in a patient with de novo Fabry disease / 영남의대학술지

Fabry disease (FD) is an X-linked, recessively inherited, rare, progressive, disorder of glycosphingolipid metabolism affecting multiple organs resulting in organ dysfunction. It is rare to find only one FD affected subject with a de novo mutation. Here we report a case of a 41-year-old Asian male diagnosed with de novo FD. Comprehensive ophthalmological evaluation was performed using slit lamp, color fundus photography, optical coherence tomography, fluorescein angiography, and indocyanine green angiography. On slit lamp examination, cornea verticillata and slightly tortuous, and aneurysmal dilatation of inferior bulbar conjunctival vessels were observed. Other imaging modalities showed unremarkable findings. Cornea verticillata and inferior bulbar conjunctival vascular abnormalities may be detected earlier than other ocular abnormalities in de novo FDs like hereditary FDs.

C-type Anterior Lamellar Keratoplasty Using Cryopreserved Leftover Cornea for Terrien's Marginal Degeneration

PURPOSE: To report a case of Terrien's marginal degeneration treated with C-type anterior lamellar keratoplasty using cryopreserved leftover cornea. CASE SUMMARY: A 63-year-old female visited our clinic because of left ocular discomfort and visual deterioration over several years. The patient had +2.25 Dsph = -5.00 Dcyl × 111° of astigmatism, and best corrected visual acuity was 20/20. Microscopic slit lamp examinations revealed an approximately 10.0 mm width semilunar shaped stromal opacity with surrounding stromal lipid deposit, as well as superficial neovascularization with thinning at superior perilimbal cornea. Anterior segment optical coherence tomography confirmed extreme thinning at the opacified cornea. The patient was diagnosed with Terrien's marginal degeneration. To prevent corneal perforation, C-type anterior lamellar keratoplasty using cryopreserved leftover cornea was performed. After 18 months after operation, donor graft was successfully attached via the anterior segment optical coherence tomography and microscopic slit lamp examination and graft rejection was not observed. CONCLUSIONS: C-type anterior lamellar keratoplasty using a cryopreserved cornea can be an effective therapeutic strategy for Terrien's marginal degeneration.

Clinical Analysis of Factors Affecting Successful Occlusion Treatment and Visual Recovery Time in Amblyopia

PURPOSE: To evaluate the factors affecting successful occlusion treatment and visual recovery time in patients with amblyopia when best corrected visual acuity (BCVA) improved up to 1.0 after occlusion. METHODS: Forty-eight patients aged 2 to 13 years old with amblyopia due to refractive errors or strabismus were selected. The duration of treatment needed to achieve a BCVA of 1.0 was compared according to the cause of amblyopia (anisometropia, strabismus, combined), initial BCVA of the amblyopic eye, and the age at treatment, as well as other factors. RESULTS: The mean age of amblyopic treatment was 5.4 years old and the mean duration of treatment was 22.9 months. The duration of treatment was longer in children whose initial BCVA was lower than 0.2, those with spherical equivalent of the amblyopic eye higher than +3.0D and those older than 6 years old. However, there were no significant differences according to the cause of amblyopia. CONCLUSIONS: The duration of treatment needed to achieve a BCVA of 1.0 was prolonged when the initial BCVA in the amblyopic eye was lower than 0.2, the age at treatment was more than 6 years old, or the spherical equivalent of the amblyopic eye was higher than +3.0D at treatment. These factors can be used to predict the duration of occlusion treatment.

Clinical Characteristics of Intraocular Foreign Body and Analysis of Prognostic Factors

PURPOSE: To investigate clinical characteristics of post-traumatic intraocular foreign body (IOFB), which occurred between 2006 and 2010, and prognostic factors associated with final visual outcome. METHODS: A retrospective chart review was performed of patients with IOFB who visited our clinic from January 1, 2006 to December 31, 2010, and who were followed up for more than 6 months. Cross tabulation and correlation analyses were conducted to evaluate the predictive factors related to final visual acuity. RESULTS: A total of 36 eyes (35 patients) were included in this study. The mean age was 44.2 years, and 33 patients (94.3%) were male. The most common cause of IOFB was lawnmower-related activity (12 patients; 33.3%) and hammering-related activity (11 patients; 30.1%). Among analyzed prognostic factors, only initial visual acuity was significantly correlated with visual outcomes (p < 0.001). CONCLUSIONS: Compared with previous studies, lawnmower and hammering-related activities were still the most common causes of IOFB, however, the incidence of occurrence in the 40's and 50's was relatively higher than in previous studies. Considering the poor visual outcome of IOFB even after proper surgical treatment, using proper eye protection should be emphasized in a dangerous work environment to prevent ocular trauma.
