Purpose: To investigate the preoperative clinical factors affecting the refractive outcome after laser-assisted subepithelial keratomileusis (LASEK). Methods: This retrospective study was conducted on 58 patients (116 eyes) who underwent bilateral LASEK using the MEL60. The outcome efficacy and predictability of LASEK was examined by analyzing data including age, gender, preoperative uncorrected visual acuity, preoperative refraction (spherical equivalent and cylindrical diopter), central corneal thickness, tear breakup time, and Schirmer test through multiple logistic regression analysis. Results: The preoperative factor associated with postoperative uncorrected visual acuity was the amount of preoperative spherical equivalent. Greater preoperative spherical equivalent was associated with decreased efficacy. Predictability was also associated with the amount of preoperative spherical equivalent. Greater preoperative spherical equivalent was associated with decreased predictability. The other preoperative factors including sex, age, preoperative uncorrected visual acuity, amount of preoperative cylinder diopter, intraocular pressure, tear breakup time, Schirmer test and central corneal thickness did not show any association with efficacy or predictability. Conclusions: The preoperative spherical equivalent was determined as the most important prognosis factor in LASEK, as it is in PRK or LASIK. J Korean Ophthalmol Soc 2010;51(8):1064-1070

Purpose: To report a case of hypotony maculopathy after silicon oil removal treated by intravitreal gas injection. Case summary: A 35-year-old women presented with decreased visual acuity of the right eye for two weeks. Retinal detachment with peripheral retinal tears was observed in the patient’s right eye. Pars plana vitrectomy including lensectomy, endolaser photo-coagulation and silicone oil injection was performed. Silicone oil removal was performed to improve patient’s visual acuity two months after the operation. After the silicone oil removal, visual acuity was decreased to hand motion, and intraocular pressure was decreased below 3 mmHg while observing chorioretinal folding in fundus for two months. Intraviteal C3F8 gas injections were performed three times in the two months after silicone oil removal. After three gas injections, gradual reduction of chorioretinal folding was observed. Visual acuity was improved to 0.2 and IOP was maintained at 8 to 10 mmHg for 18 months after the last gas injection. Conclusions: Intravitreal gas injection offers a safe and effective method for treating hypotony retinopathy after silicon oil removal.

Purpose: To investigate the risk factors for dry eye in thyroid-associated ophthalmopathy patients. Methods: The present retrospective study was conducted on 78 eyes in 39 patients diagnosed with thyroid-associated ophthalmopathy. The risk factors for dry eye in thyroid-associated ophthalmopathy patients were examined by analyzing data including tear break-up time, Schirmer’s test, age, gender, thyroid function status, palpebral fissure width, lagophthalmos, eyelid retraction, and exophthalmos through multiple logistic regression analysis. Results: The risk factors for dry eye disease were palpebral fissure width (OR = 3.422, p = 0.022) and lagophthalmos (OR = 13.068, p = 0.049). Age, gender, thyroid hormone status, eyelid retraction and exophthalmos did not show significant association with dry eye in multiple logistic regression analysis. The only risk factor for tear film break-up time less than 10 seconds was palpebral fissure width (OR = 2.787, p = 0.045), and none of the risk factors for Schirmer’s test less than 10 mm at 5 minutes were statistically significant. Conclusions: Risk factors for dry eye in thyroid ophthalmopathy patients were palpebral fissure width and lagophthalmos. J Korean Ophthalmol Soc 2011;52(7):771-776

<b>Purpose:</b> To evaluate the refractive outcomes of small incision lenticule extraction (SMILE) in high myopia patients compared with mild to moderate myopia patients. <b>Methods:</b> This study included 332 eyes of 166 myopic patients treated with SMILE using Visumax 500 kHz femtosecond laser. Treated eyes were divided into 2 groups according to preoperative spherical equivalent (SE): mild to moderate myopia (A group, <-6.0 D) and high myopia (B group, ≥-6.0 D). Follow-up visits were at 1 day, 1 week, 1 month, 3 months, and 6 months. The outcome measures included uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (BDVA), postoperative SE, efficacy index, safety index and predictability. <b>Results:</b> Preoperative SE was -4.85 ± 0.86 D in the A group and -7.70 ± 1.0 D in the B group. No differences were observed between -0.04 ± 0.29 D in the A group and -0.30 ± 0.37 D in the B group at 6 months postoperatively (<em>p</em> = 0.062). At 6 months postoperatively, 98.3% and 97.3% had UDVA of 20/25 or better in the A group and B group, respectively. In the A group, 97.3% and 100% were within ±0.5 D and ±1.0 D of intended correction and in the B group, 91.7% and 96.9% were within ±0.5 D and ±1.0 D, respectively. Efficacy indices were 1.02 ± 0.19 in the A group and 0.99 ± 0.18 in the B group. Safety indices were 1.16 ± 0.16 in the A group and 1.14 ± 0.16 in the B group. The efficacy and safety indices were not significantly different between the A and B groups at 6 months postoperatively (<em>p</em> = 0.09, <em>p</em> = 0.695, respectively). `<b>Conclusions:</b> This study showed that SMILE is effective and safe for correcting high myopia as well as mild to moderate myopia.

For the purpose of evaluation of clinical characteristics in multiple rib fracture due to accident , 24 cases treated by surgical rib fixation using Judet`s strut for multiple rib fracture and flail chestduring the period from June 1993 to October 1994 were reviewed. There were 17 males and 7 females.They ranged in age from 19 years old to 56 years old. The causes of rib fracture were traffic accident in 18 cases, fall down in 3 cases, compression in 2 cases stab wound in 1 case. The number of rib fracture were five in 7 cases, six in 5 cases, four in 5 cases, three in 3 cases. Associated intrathoracic injuries were hemopneumothorax in 12 cases, hemothorax in 10 cases, lung laceration or hemorrhagic contusion in 7 cases. Associated extrathoracic injuries were abdominal injuries in 21 cases, orthopedic problem in 7 cases, head trauma in 4 cases. The most common fractured site was posterolateral portion of the ribs. The causes for operation were flail chest, severe rib displacement and pain, hemothorax or hemopneumothorax with continuous air leakage and stab wound. There were 6 postoperative complications ; one with hydrothorax, two with fibrothorax, two with wound infection and one case of death due to multiful organ failure. Postoperatively, all patients became comfortable and complained less painful. Twenty patients restored spontaneous breathing without ventilator support, three patients were ventilated during a day and one patient expired after 2 days. There were no morbidity and mortality related to operation.

Pulmonary sequestration is an uncommon congenital pulmonary malformation characterized by presence of nonfunctioning lung tissue which receives its blood supply mostly from the anomalous systemic arteries - descending thoracic aorta or abdominal aorta, subclavian artery, innominated artery and internal mammary artery, etc. In our country, 39 cases were reported previously. The patient was a 40 years old woman and admitted due to productive cough for 1 year. The chest X-ray and chest C-T showed a dense mass containing a large cavity with air-fluid level and multiple radiolucent cysts in the right lower lung field. On the operative field, we could identify an aberrant large artery [ $\phi$7mm which arose directly from the descending thoracic aorta at eighth thoracic spinal level and fed the sequestrated portion of the right lower lobe. The aberrant artery was double ligation after division. Only sequestrated lobe on the superolateral lesion of the right lower lobe was resected because of nonseparated lobes in all the right lobes. An abnormal vein and bronchiole were ligated with black silk. The patient`s postoperative course was unevenful.
