Purpose: To report three cases of ophthalmoplegic migraine which is a rare condition characterized by the association of headaches with an oculomotor nerve palsy. Case summary: A 44-year-old male and two eight-year-old females were presented with diplopia developed after headaches. All of the three patients showed abnormal eye movement and they had past episodes of transient diplopia with headaches. Visual evoked potential (VEP), cerebrospinal fluid (CSF) examination, laboratory findings, and other neurologic tests were all normal, also there was no tumor or cerebrovascular disease on brain MRA & MRI. The symptoms of all patients improved gradually within several weeks from first the visit, with complete recovery seen in all three. Conclusions: Any patient who has a headache with paresis of the extraocular muscle should be considered for ophthalmoplegic migraine. To diagnose ophthalmoplegic migraine, family history, past medical history, associated symptoms and signs, neurologic examinations and neuroimaging tests are needed.

Purpose: To compare the results of total deviation (TD) as measured by standard automated perimetry (SAP) and measured with of Matrix Frequency-doubling Technology (FDT) in patients with preperimetric glaucoma. Methods: Fifty-two eyes of 52 patients with preperimetric glaucoma were included. Subjects were examined with Matrix FDT and Stratus optical coherence tomography (OCT), and the results of each examination were analyzed. The proportions of abnormal results in SAP TD, Matrix TD, and Matrix pattern deviation (PD) were calculated. Among the results of tests, the following correlations were evaluated: SAP TD and Matrix, and visual fields and OCT. In addition, the differences in peripapillary retinal nerve fiber layer thickness (RNFL) according to the result of SAP TD in preperimetric patients with abnormal Matrix PD were analyzed. Results: A abnormalities in SAP TD, Matrix TD and Matrix PD were found in 22 (42.3%), 34 (65.4%), 41 (78.9%) eyes, respectively. There was marginal correlation between SAP TD and Matrix PD (p=0.07). No significant correlation was found between SAP TD and OCT, although Matrix PD and OCT did show significant correlation (p

Purpose: To investigate the changes of visual field index (VFI) compared with mean deviation (MD) and pattern standard deviation (PSD) before and after cataract surgery. Methods: The present study included 77 eyes of 77 patients who were diagnosed with both glaucoma and cataracts and underwent cataract surgery. Preoperative and postoperative VFI, MD, and PSD were examined. Lens opacity type was classified as cortical, nucleosclerosis, or posterior subcapsular opacity (PSCO), and the MD, PSD, and VFI were compared before and after cataract surgery. Results: Preoperative and postoperative MD were -13.648.97, -11.949.67(p=0.113), PSD were 6.183.30, 5.913.31(p=0.344), and VFI were 67.0033.43, 70.5533.19(p=0.440), respectively. MD showed statistically significant difference in cortical and PSCO type before and after cataract surgery. PSD (p=0.025) and VFI (p=0.020) showed a statistically significant difference in cortical type. Conclusions: VFI is an effective parameter to monitor the progression of glaucoma in cataract patients with nucleosclerosis and PSCO, but has limitations in cataract patients with cortical opacity.

Purpose: To investigate the effect of rigid gas permeable (RGP) contact lenses in patients with corneal scar and opacity following repair of corneal perforations. Methods: A total of 10 eyes from 10 patients undergoing repair of corneal perforating injuries and fitted with RGP contact lenses were examined in the present study. The mean postoperative 3-month visual acuities, refraction, corneal topography, keratometry, best corrected visual acuities with spectacles and RGP lenses at an average of postoperative 3 months were evaluated. Results: Eight eyes had corneal opacities at the central and 2 eyes at the peripheral portion. Four patients had previous cataract surgery or cataract surgery with intraocular lens insertion due to traumatic cataract. The mean postoperative 3-month LogMAR visual acuity was 1.14 0.53. Corneal topography showed irregular astigmatism in all patients and the mean keratometric astigmatism was 4.03 4.06 diopters. The mean best corrected LogMAR visual acuities with spectacles was 0.91 0.64 and with the RGP contact lens was 0.25 0.35. A comparative analysis of improvement in visual acuity with the RGP contact lens over spectacle correction was found to be statistically significant (p = 0.005). Patients wore the lenses for more than 6 hours daily for the mean follow-up period (12.10 7.80 months). Conclusions: In patients with corneal scar and opacity following repair of corneal perforations, RGP contact lens fitting should be considered first before surgical corrections such as keratoplasty.

Purpose: To report the change of corneal asphericity and the relationship between asphericity and visual acuity after wearing the reverse-geometry lens. Methods: The authors reviewed out-patient records of 37 consecutive patients wearing reverse-geometry lenses. The patients were followed up from July 2004 to December 2007. The unaided visual acuity (VA), spherical equivalent (SE) and asphericity before and after wearing the lens were compared. The relationship of SE and final VA, initial astigmatism and final VA, and asphericity and final VA was also analyzed. In addition, the relationship between the increment of VA and asphericity was determined. Results: VA and SE improved and the asphericity decreased after wearing the lens (p＜0.05). There was high correlation between the spherical equivalent and final visual acuity (p＜0.001), and no correlation between asphericity and final visual acuity (p=0.358) was observed. However, the lower the initial asphericity, the greater the increment of visual acuity observed (p=0.048). Conclusions: Initial corneal asphericity can be a predictor of increment of VA after wearing reverse-geometry lenses.

Purpose: To determine the relationships among refractive error, corneal asphericity, and axial length in elementary school students. Methods: One hundred eleven eyes from 56 subjects were included in this study. All subjects underwent cycloplegic refraction corrected to the spherical equivalent. Axial length was measured, and corneal topography was performed. Corneal asphericity was assessed using eccentricity (e) calculated according to the formula Q=-e2. The relationship among spherical equivalent, asphericity, and axial length was determined using a linear regression model. Results: Subjects were between 8 and 12 years of age (mean, 9.99±1.33). The average spherical equivalent was -1.38±2.08D (-7.13~2.63D), the average axial length was 23.84±1.17 mm (20.10~26.37 mm), and the average corneal asphericity was -0.29±0.10 (-0.55~-0.07). An increase in myopia was positively correlated with an increase in axial length (p
