Purpose: To investigate the clinical manifestation and response to high-dose steroid therapy in Korean optic neuritis patients. Methods: We retrospectively reviewed the medical records of 13 patients diagnosed with optic neuritis who were treated with high-dose steroid and who were followed-up for more than three months in Seoul National University Hospital between January 2005 and December 2008. Results: Pain on extraocular movement (EOM) and disc swelling were observed in 61% (8/13) patients diagnosed with optic neuritis. Visual acuity (VA) improved to more than 20/40 in 77% (10/13) of patients after high-dose steroid therapy. The patients who resolved within one month recovered VA a mean of 18 days after onset. The recovery period had nothing to do with the initial time of high-dose steroid therapy. Conclusions: Pain on EOM was less frequently observed and disc swelling was more frequent in Korean patients than have been reported in Caucacian patients. The recovery period of optic neuritis was not influenced by the initial time of high-dose steroid therapy. J Korean Ophthalmol Soc 2011;52(9):1083-1088

목적: 황반을 침범하지 않은 망막분지정맥폐쇄에 동반된 황반부종 치료 증례를 보고하고자 한다. 증례요약: (증례 1) 64세 여성이 우안 상이측의 황반을 침범하지 않은 망막분지정맥폐쇄에 따른 황반부종을 보였다. 유리체강내 베바시주맙 주입술과 정맥폐쇄 부위에 레이저 광응고술을 시행하였고, 황반부종 소실과 함께 경성삼출물의 축적을 보였다. 경성삼출물이 흡수되며 교정시력은 0.2에서 0.5로 향상되었다. (증례 2) 53세 남성이 좌안 상이측 혈관궁 바깥쪽의 망막분지정맥폐쇄에 따른 황반부종을 보였다. 유리체강내 베바시주맙 주입술을 2회 시행하였고, 정맥폐쇄 부위에 레이저 광응고술을 시행하였다. 황반부종 소실과 함께 경성삼출물의 축적을 보였으나, 경성삼출물이 흡수되며 교정시력은 0.1에서 0.4로 호전되었다. 두 증례 모두 황반부종의 재발을보이지 않았다. 결론: 황반을 침범하지 않은 망막분지정맥폐쇄에 동반된 황반부종을 베바시주맙 및 레이저 광응고술 복합 요법으로 치료한 증례를 보고한다 Purpose: To report two cases of patients treated for macular edema associated with extramacular branch retinal vein occlusion(BRVO). Case summary: (Case 1) A 64-year-old female presented with macular edema (ME) associated with superotemporal extramacular BRVO. The ME was resolved but hard exudate (HE) deposited after combined therapy of intravitreal bevacizumab injection and laser photocoagulation of the BRVO area. Best corrected visual acuity (BCVA) improved from 0.2 to 0.5 following absorption of HE. (Case 2) A 53-year-old male presented with ME associated with extramacular BRVO outside the superior vascular arcade. ME was treated with 2 monthly injections of bevacizumab and laser photocoagulation in the BRVO area. Although HE deposited after resolution of ME, it was absorbed and BCVA improved from 0.1 to 0.4. The ME did not recur in either patient. Conclusions: We report 2 cases managed with combined therapy of intravitreal bevacizumab injection and laser photocoagulation for ME associated with extramacular BRVO.

Purpose: We report a case of a full-thickness macular hole which occurred many years after a blunt eye trauma leading to choroidal rupture. Case summary: A 50-year-old male visited our clinic with a complaint of decreased vision in his left eye 2 years in duration. He experienced a blunt trauma to his left eye with a baseball when he was 6 years old, although he did not complain of any visual disturbance in the left eye at that time. Fundus examination revealed a full-thickness macular hole with vertical fibrotic scar at the temporal side of the macula, which was thought to be a choroidal rupture induced by the previous blunt eye trauma. We performed vitrectomy and intravitreal tamponade injection. Two months later, the full-thickness macular hole completely closed and visual acuity of the left eye improved.

<b>Purpose:</b> To report a case of ocular syphilis presenting as bilateral optic neuritis. <b>Case summary:</b> A 25-year-old man presented with visual difficulty in both eyes that had begun 2 weeks previously. Best corrected visual acuity was 0.7 in the right eye and 0.1 in the left eye. Anterior segment was normal. On fundoscopic examination, optic disc swelling was found in both eyes. Color vision was abnormal in the left eye. The visual field (VF) showed peripheral constriction in the right eye and generalized reduction in the left eye. Fluorescein angiography revealed early, bilateral leakage of dye from the optic disc with multiple hot spots in the chorioretinal level. Serology was positive for fluorescent treponemal antibody absorbance (FTA-ABS) IgM, IgG and rapid plasma reagin test. A test of the cerebrospinal fluid was positive for venereal diseases research laboratory and FTA-ABS IgG. A diagnosis of syphilitic optic neuritis was made and the patient was treated with antibiotics. Six months later, visual acuity was 1.0 in the right eye and 0.8 in the left eye. There was no disc swelling on both fundoscopy and optical coherence tomographs. VF also improved after treatment, with the restoration of central vision. <b>Conclusions:</b> Syphilis can present as optic neuritis. Clinicians should consider serologic examination for syphilis and then initiate appropriate antibiotic treatment. J Korean Ophthalmol Soc 2014;55(7):1115-1120 Key

Purpose: To report a case of long anterior lens zonule and pigment dispersion syndrome. Case summary: A 67-year-old female visited our clinic with complaint of visual disturbance in the left eye. She had no history of nyctalopia. Visual acuity was 0.6 in the right eye and 0.4 in the left eye. Intraocular pressure was 12 mm Hg in the right eye and 16 mm Hg in the left eye. Nuclear sclerosis was observed in the left lens. There was no pseudoexfoliative material observed. In the left eye, long anterior zonules with brown pigmented lens striae were spotted irregularly in every direction of the anterior lens. On gonioscopy, the angle was open, and dense, uniform, trabecular meshwork pigmentations were observed at the interior 120 degrees. On fundus examination, cup-to-disc ratio was 0.4 in the right eye, 0.3 in the left eye, and multiple hard exudates were observed in both retinas. Axial length was 22.03 mm in the right eye and 21.84 in the left eye. Anterior chamber depth was 2.71 mm in the right eye and 2.47 mm in the left eye. Defects in the retinal nerve fiber or visual field examination were not observed and pigment dispersion syndrome was diagnosed. The patient showed no significant change at the 9-month follow-up. Conclusions: We diagnosed atypical pigment dispersion syndrome associated with long anterior zonules and pigmented lens striae. Late onset retinal degeneration should be ruled out with chromosomal analysis if patients show nyctalopia, retinal pigment epithelium atrophy, or family history.

Hoffer Q와 SRK/T 인공수정체 도수 계산 공식의 이론적 임상적 비교

Purpose: To evaluate the biometric conditions causing increased disparity in the calculation of intraocular lens (IOL) power between the Hoffer Q and SRK/T formulas. Methods: A prospective comparative study was conducted on 365 uneventful, cataract surgeries performed at a tertiary care center by one surgeon. The IOL power was calculated using both the Hoffer Q and SRK/T formulas with A-scan biometry. For a selected IOL power, the expected disparity between the 2 formulas (EDF) was measured and the EDF value was used to categorize the cases. The resultant error associated with each formula was determined at postoperative 6 weeks. KAL was defined as the product of mean corneal power (K) and axial length (AL). Postoperative errors of both formulas were calculated and their association with preoperative biometry measurements analyzed. Results: In 17.8% of the cases, the EDF was larger than 0.4 D, possibly leading to different IOL diopter recommendations. The EDF value and the product of corneal curvature and axial length were significantly correlated (R2 = 0.855, p < 0.001). Multiple regression analysis of causative preoperative biometric factors on the postoperative formula errors showed that astigmatism, anterior chamber depth (ACD), and lens thickness (LT) were significantly associated with Hoffer Q error and SRK/T error. Conclusions: Overall, both formulas performed very well when recommending the correct IOL power. The cause of disparity between the predicted refraction for the 2 formulas was more associated with KAL than K or AL alone. Astigmatism, ACD, and LT were the causative factors for the postoperative errors in both formulas. J Korean Ophthalmol Soc 2014;55(1):85-92
