Purpose: The hydrated form of lime used for marking lines on the ground is a corrosive alkali. The harmful effects of lime are well known, and chemical burns of human tissue due to lime have been reported. We report a case of chemical injury of the cornea caused by exposure to lime at a playground. Methods: A 3-year-old male patient presented with decreased visual acuity after slipping on the playground. His best corrected visual acuity (BCVA) was 20/40 in the right eye (OD), and hand motion in the left eye (OS). On biomicroscopic examination, bilateral corneal opacity and corneal erosion were observed. In the OS, the corneal opacity involved the visual axis and resulted in vision impairment. He was treated with eye drops. Results: After treatment for 3 months, his corrected visual acuity was 20/30 in the OD, and 20/125 in the OS. The corneal opacity was not improved and corneal thinning was observed in the OS. After 1 year, BCVA was 20/25 in the OD, and 20/100 in the OS. Conclusions: The lime used for marking white lines on the ground can cause opacity and thinning of the cornea. Other, safer methods for line marking should be considered.

목적: 비접촉경면현미경, 이중샤임플러그전안부 사진기 및 초음파 각막두께측정계를 이용하여 중심각막두께의 측정치를 비교하고자 하였다. 대상과 방법: 정상인 70명 70안을 대상으로 비접촉경면현미경, 이중샤임플러그전안부 사진기 그리고 초음파 각막두께측정계로 측정한 중심각막두께를 비교하고 상관관계를 알아보았다. 결과: 비접촉경면현미경, 이중샤임플러그전안부 사진기 및 초음파 각막두께측정계를 이용하여 측정한 중심각막두께는 각각 567.70 ± 31.21 μm, 557.84 ± 26.29 μm, 553.31 ± 29.69 μm로 비접촉경면현미경이 가장 두껍게 측정되었고 초음파 각막두께측정계가 가장 얇게 측정되었으며, 각 측정치 사이에 통계적으로 유의한 차이를 보였다(p<0.05). 이 중 비접촉경면현미경은 초음파 각막두께측정계보다 유의하게 두껍게 측정되었다(p<0.05). 세 검사는 높은 양의 상관관계를 보였다(r>0.900, p<0.001). 결론: 비접촉경면현미경에 의해 측정된 중심각막두께는 초음파각막두께측정계에 의해 측정된 중심각막두께보다 유의하게 두껍게 측정되어 결과 해석 시 이에 대한 고려가 필요할 것으로 생각된다. 또한 이중샤임플러그전안부 사진기로 측정한 중심각막두께가 초음파 각막두께측정계로 측정한 값에 좀 더 유사한 값을 나타내며 정상안의 중심각막두께 측정에 이중샤임플러그전안부 사진기가 비접촉경면현미경보다 초음파 각막두께측정계를 대체할 수 있는 좀 더 유용한 방법이라 생각된다. Purpose: To compare central corneal thickness (CCT) as measured using noncontact specular microscopy (NCSM), dual rotating Scheimpflug camera (Galilei??), and ultrasound pachymetry (USP). Methods: The measurements of CCT using NCSM, dual rotating Scheimpflug camera and USP in 70 eyes of 70 healthy subjects were compared. Results: The average measurements of CCT using NCSM, dual rotating Scheimpflug camera, and USP were 567.70 ± 31.21 μm, 557.84 ± 26.29 μm, and 553.31 ± 29.69 μm, respectively. The CCT measurement using NCSM was statistically significantly thicker than when measured using USP (p < 0.05). There was no significant difference between the NCSM and dual rotating Scheimpflug camera (p = 0.138). Additionally, there was no significant difference between the dual rotating Scheimpflug camera and USP (p = 0.656). A significant linear correlation was observed among the NCSM, dual rotating Scheimpflug camera, and USP (r > 0.900, p < 0.001). Conclusions: The results of the 3 methods were significantly correlated but the measurement using NCSM was significantly thicker than when using USP. CCT measurements of healthy eyes using dual rotating Scheimpflug camera were more correlated with USP than NCSM. The CCT measurements using dual rotating Scheimpflug camera is a better alternative for USP than NCSM.

Purpose: To evaluate the changes of anterior chamber depth (ACD), Axial length (AXL) after combined vitrectomy and cataract surgery and to analyze the association with refractive errors. Methods: In 22 eyes who underwent combined vitrectomy and cataract surgery (PPV-Phaco group), 20 eyes who underwent vitrectomy-only (PPV-only group) and 28 eyes who underwent uncomplicated cataract surgery (Phaco-only group), ACD and AXL were measured with IOL master (Carl Zeiss Jena, Germany) preoperatively and 3 months postoperatively. We compared the preoperative desired refraction and postoperative 3 months refraction. Results: ACD were increased in PPV-Phaco group and Phaco-only group (all, p < 0.001) and this change was more prominent in PPV-Phaco group (p = 0.030). In PPV only group, ACD was decreased (p < 0.001). The AXL after surgery was not significant different from the preoperative AXL in PPV-Phaco and PPV only groups (p = 0.612, p = 0.090). But the AXL was decreased in Phaco-only group (p = 0.022). Hyperopic shifting were noticed in PPV-Phaco and phaco-only groups, but myopic shifting was noticed in PPV-only group. However, these changes were not statistically significant (p = 0.292, p = 0.251, p = 0.068). Conclusions: ACD was increased after combined vitrectomy and cataract surgery. AXL was not changed. The hyperopic shifting was noticed after combined vitrectomy and cataract surgery, but was not statistically significant.

Purpose: To report the effectiveness of selective laser trabeculoplasty (SLT) in patients with intraocular hypertension refractory to maximum tolerated medical therapy after intravitreal triamcinolone acetonide (IVTA). Case summary: The records of 3 patients with steroid-induced intraocular hypertension that did not respond to maximum tolerated medical therapy were retrospectively reviewed. The patients received SLT instead of filtering surgery or Argon laser trabeculoplasty. The mean intraocular pressure (IOP) of 13.7 mm Hg increased to 30.7 mm Hg within 13 days of IVTA. IOP was uncontrolled despite maximum tolerated medical therapy. Patients underwent SLT 15.3 weeks after IVTA. Mean IOP decreased to 16 ± 3.0 mm Hg after 1 day, 19.7 ± 8.0 mm Hg after 1 week, 17 ± 8.0 mm Hg after 1 month, 12.3 ± 2.9 mm Hg after 3 months and 12.3 ± 0.6 mm Hg after 4 to 6 months. The number of IOP lowering drugs were decreased to 1 from 4.3 after 6 months of SLT. Conclusions: SLT may be effective and safe for the treatment of steroid-induced intraocular hypertension refractory to maximum tolerated medical therapy. J Korean Ophthalmol Soc 2011;52(7):876-880
가변각막보정 주사레이져편광측정기를 이용한 국소 시야 결손을 가지는 녹내장 환자의 진단

Purpose: To evaluate the ability of scanning laser polarimetry parameters and a novel deviation-map algorithm to discriminate between healthy and early glaucomatous eyes with localized visual field defects confined in one hemifield. Methods: In this prospective case-controlled study, 61 glaucomatous eyes with localized visual field defects and 66 normal controls were enrolled. Humphrey field analyzer 24-2 glaucoma hemifield test and scanning laser polarimetry (GDx-VCC?) were used. Results: There were significant differences in the mean parametric values of TSNIT average, superior average, inferior average, and TSNIT SD (P<0.05) between the glaucoma group and normal subjects. The sensitivity of each GDx-VCC variable was as follows: TSNIT average, 47.5%; superior average, 31.1%; inferior average, 47.5%; and TSNIT SD, 24.6% (when abnormal was defined as P<0.05). The overall sensitivities combining each probability scale and severity score at 80%, 90%, and 95% specificity were 90.2%, 72.1%, and 59%, respectively. There was a statistically significant correlation between the GDx-VCC severity score and the visual field severity score (P<0.05). Conclusions: GDx-VCC parameters may not be sufficiently sensitive to detect glaucomatous patients with localized visual field damage. Our algorithm using the GDx-VCC deviation map may enhance the understanding of GDx-VCC in terms of the locality, deviation size, and severity of localized RNFL defects in eyes with localized visual field loss.
