In order to study the clinical characteristics of primary acute angle closure glaucoma, we analyzed the data of 72 eyes from 63 patients with the disease from January 1, 1990 to December 31, 1993 to the Department of Ophthalmology of Chonnam University Hospital. The mean age of the patients was 63.3 years and female and male ratio was 5.9:1. And the mean IOP at first visit was 53.2 mmHg. There was no significant difference of rop between right and left eyes, and 11 patients had the disease in both eyes. 38% of the patients developed the disease in winter time. The development of the disease was closely associated with physical illness and emotional stress. 39 eyes(49.3%) of them was required filtering surgery because medication and laser treatment was insufficient to lower IOP.

PURPOSE: We studied the diagnostic significance of bone scan in evaluation of bone metastasis by lung cancer, prevalence rate, and the causes of false positive bone scan and soft tissue accumulation of bone seeking agent. MATERIALS AND METHODS: The subject included 73 lung cancer patients with bone scan. We analyzed the frequency of bone metastasis, its distribution and configuration, and any relationship between bone pain and corresponding region on bone scan. The positive findings of bone scan were compared with simple X-ray film, CT, MRI and other diagnostic modalities. The false positive bone scan and the soft tissue accumulation of bone seeking agent were analized. RESULTS: The positive findings on bone scan were noted in 26 cases(36%) and they were coexistant with bone pain in 30%. The correspondance between bone scan and bone X-ray was 38%. False positive bone scans were seen in 12 cases(16%), which include fracture due to thoracotomy and trauma, degenerative bone diseases, and bifid rib. Accumulation of bone seeking agent in soft tissue were seen in 13 cases(18%), which included primary tumor, enlarged cervical lymph node, pleural effusion, ascites and pleural thickening. CONCLUSION: Bone scans should be carefully interpreted in detecting bone metastasis in primary malignancy, because of the 16% false positivity and 18% soft tissue accumulation rate. It is very important to note that the correlation between bone pain and positive findings of bone scans was only 38%.

Journal of the Korean Ophthalmological Society 2020;61(11):1265-1272
Purpose:
To compare the accuracy of standard and total keratometry data obtained using the Barrett Universal II and Barrett Toric Calculator.
Methods:
In total, 111 eyes of 111 patients who visited our hospital for cataract surgery from February 2019 to September 2019 were included in this study. Total keratometry and standard keratometry data were obtained using the Barrett Universal II and the Barrett Toric Calculator; mean absolute errors were derived by using preoperative IOL Master 700® (Carl Zeiss Meditech AG, Jena, Germany) data and 2-month postoperative manifest refraction data. The mean absolute errors of the two methods were compared in terms of a posterior corneal astigmatism greater than 0.3 diopter (D) in patients fitted with Toric intraocular lenses.
Results:
Using the Barrett Universal II formula, the mean absolute error spherical equivalent difference between total keratometry and standard keratometry was 0.021 ± 0.102 D (p = 0.65) when the Barrett Toric Calculator was used. The mean absolute error differences between the two methods were 0.015 ± 0.121 D for the spherical equivalent (p = 0.80) and 0.005 ± 0.870 D for the cylinder measurement (p = 0.94). In terms of a posterior corneal astigmatism greater than 0.3 D, the mean absolute error spherical equivalent and cylinder measurement differences were -0.020 ± 0.107 D (p = 0.70) and -0.023 ± 0.055 D (p = 0.50) in patients fitted with Toric intraocular lenses.
Conclusions
The total keratometry method, which directly measures posterior corneal curvature, yields data comparable to those of the standard keratometry method. When the posterior corneal astigmatism was greater than 0.3 D, we found no significant difference between the total keratometry and standard keratometry data of patients fitted with Toric intraocular lenses.

PURPOSE: To report a case of irregular astigmatism caused by a free flap during laser-assisted in situ keratomileusis (LASIK) surgery that was treated with a flap rotation based on postoperative topography. CASE SUMMARY: A 21-year-old female underwent LASIK, which was complicated by a free cap on her right eye. Because the gentian violet markings were no longer present, the exact orientation of the cap was unknown. At 3 months after surgery, the astigmatism of the right eye was −3.00 diopters (D) with an uncorrected visual acuity (UCVA) of 0.4, and the astigmatism of the left eye was −0.75 D with an UCVA of 1.0. The corneal topography was analyzed in order to return to the existing position. Free cap repositioning was performed and irregular astigmatism was corrected to improve the UCVA to 1.0. CONCLUSIONS: If the preoperative markings cannot be identified on a free flap during LASIK, secondary postoperative corneal topographic analysis can be performed to restore the corneal free flap to its original position to minimize astigmatism with good visual outcomes.

Journal of the Korean Ophthalmological Society 2021;62(2):201-206
Purpose:
To calculate the intraocular lens (IOL) power using the Shammas-PL formula after laser in-situ keratomileusis (LASIK).
Methods:
Forty-one eyes of 29 patients that had undergone cataract surgery from September 2018 to September 2019 after LASIK were enrolled in this study. A preoperative AL-Scan® (Nidek Co., Gamagori, Japan) was used to measure the axial length, anterior chamber depth, and corneal curvature. An IOL power calculation was performed using the Shammas-PL (post LASIK) formula. Mean absolute error (MAE) and mean arithmetic error (MARE) were calculated using preoperative manifest refraction and postoperative manifest refraction.
Results:
Of the 41 eyes, 15 eyes (36.6%) were relatively hyperopic-shifted after surgery compared to the predicted refractive error before surgery, 25 eyes (61%) showed a relative myopic shift, and one eye (2.4%) showed no change with respect to the previous refractive predicted error. Refractive errors before cataract surgery were not related to myopic, emmetropic, or hyperopic shifting after surgery (p > 0.05).
Conclusions
When cataract surgery using the Shammas-PL formula was performed after LASIK, myopic shifting was more common than hyperopic shifting. The MAE was greater in myopic-shifted cases than that of hyperopic-shifted cases. Thus, it is better to determine IOL power toward the hyperopic side than the target refractive prediction.

Primary malignant lymphoma of the breast is rare. The incidence of primary malignant lymphomas of the breast is 0.04% to 0.5% of all malignant tumors of the breast and 0.07% of all non-Hodgkin's lymphomas, and comprises 1.7% of extranodal malignant lymphomas that occur in Western countries. The incidence of mucosa- associated lymphoid tissue (MALT) lymphoma of the breast is reported to be between 0% and 75% of all primary malignant breast lymphomas in United States and Japan, but the incidence in Korea is unknown. MALT is characterized by indolent behavior and good has a prognosis. The authors report on a patient who has a primary MALT lymphoma of the breast. She was treated by surgical excision, which was followed by radiation therapy. Histologically, her lymphoma type transformed into a diffuse large B-cell tumor after 10months. She received combination chemotherapy and achieved a complete state of remission. She then underwent autologous peripheral blood stem cell transplantation along with high dose chemotherapy. To our knowledge, this is the first case report in the literature in Korea.
