Purpose: To evaluate surgical results after the reconstruction of isolated medial orbital wall fractures. Methods: We performed a retrospective chart review of patients with isolated medial orbital wall fractures who underwent reconstruction using the transcaruncular approach from March 2012 to October 2013. Computed tomography (CT) was performed before and after surgery. Postoperative follow-ups were conducted at 1 week, 1 month, and 3 months. Diplopia, ocular motility, postoperative complication, and exophthalmometry were recorded at each follow-up visit. Preoperative and postoperative enophthalmos was quantified using Hertel exophthalmometry and a quantitative method for the area of the circular sector under the chord (CA)/orbital area (OA) ratio at the CT scan. Patients were divided into either the incomplete or complete reduction groups based on the degree of reduction observed on postoperative CT. Results: We evaluated 55 patients (42 males, 13 females) with an average age of 36 years. Five of 55 patients with preoperative enophthalmos of more than 2 mm obtained good symmetry after surgery. Diplopia at primary gaze was resolved in 9 of 9 patients and 2 patients had residual diplopia on lateral gaze. The difference of exophthalmometry and CA-to OA ratio between before and after reconstruction was not significantly changed in either the incomplete or complete groups. Conclusions: Enophthalmos and diplopia were well corrected in all subjects. If reduction was successfully performed in the anterior portion of medial orbital wall fracture, clinically significant enophthalmos might be preventable even if complete reduction was not obtained.

Purpose: We investigated the effects of dominant eye and contextual background on predominance during binocular rivalry. Methods: 10 subjects were recruited for the present study. Dominant eye was determined using the hole-in-the-card test. In experiment 1, subjects viewed the stimuli through anaglyph filters and reported the predominance of color. The subject’s responses were compared with the color on the dominant eye. To investigate the influence of color dominance and contextual color, we conducted the experiment with added contextual color information target through switched-anaglyph filters. In experiment 2, the subject viewed the stimuli through the polarized filters and reported the predominance of orientation. The subject's responses were compared with the grating on dominant eye. To rule out the effect of stimulus size, we conducted the experiment with a smaller target. We designed the additional experiment to investigate the influence of contextual grating information on binocular rivalry. Results: 10 subjects were evaluated. In experiment 1, 8 of 10 subjects reported that eye preference was highly correlated with dominant eye. This finding is significant without reference to color. In experiment 2, 7 of 10 subjects reported that eye preference was highly correlated with dominant eye. This finding is significant without reference to size. In experiment 1-2 and 2-2, all subjects reported that predominance of context contradictory target increased. Conclusions: We found the relationship between the dominant eye and eye preference. Experiment 1-2 and 2-2 showed that contradictory contextual information increases target predominance during binocular rivalry. Overall, our results indicate that the contextual background reduce the stimulus strength of the context-congruent target; it would correspond to an increase in the dominance duration of the context-contradictory target 목적: 우세안과 선호안의 관련성 및 시자극 주변 맥락이 양안 경합에 어떤 영향을 끼치는지 알아보고자 한다. 대상과 방법: 성인 10명이 참가했으며 우세안은 hole-in-the-card test로 판별했다. 실험1은 적록안경으로 백색의 시자극을 주시하여 색깔을 보고하게 하였으며 우세안에서 보이는 색과의 관련성을 보았다. 색의 우성과 주변 맥락의 영향을 보기 위해 적록안경의 좌우를 바꾸고 배경색을 더하여 실험을 시행하였다. 실험2는 편광안경으로 시자극을 주시하여 격자방향을 보고하게 하였으며 우세안에서 보이는 격자와 관련성을 보았다. 자극크기의 영향을 보기 위해 작은 제시자극으로 실험을 시행하였으며 주변 맥락의 영향을 보기위해 제시자극 배경에 격자를 추가하여 실험을 시행하였다. 결과: 총 10명이 대상이었으며 실험1에서 10명 중 8명이 우세안과 선호안이 유의한 연관성을 보였으며 적록안경 필터를 반대로 착용했을 때도 동일했다. 실험2에서는 10명 중 7명이 우세안과 선호안이 유의한 연관성을 보였으며 작은 제시자극으로 추가 시행하였을때 동일한 연관성을 보였다. 실험1-2와 실험2-2에서는 모든 피험자가 유의하게 주변 맥락과 반대되는 제시자극을 선택하였다. 결론: 본 연구에서는 시자극의 양안 경합 상황에서 우세안과 선호안의 관련성을 확인할 수 있었다. 실험 1-2와 2-2에서는 주변 맥락과 반대되는 제시자극이 우세한 결과를 확인하였다. 주변 맥락 효과는 배경과 일치하는 제시자극의 강도를 감소시켜 배경과 반대되는 제시자극의 지각적 우위를 가져오리라 생각한다.

Purpose: To report a vitrectomy performed on a patient with an endocapsular hematoma whose visual acuity changed with her position. Case summary: A 92-year-old woman visited our hospital complaining of a visual acuity change in her left eye with good visibility while standing but poor visibility when lying. She was taking aspirin, had underlying hypertension, diabetes, and heart failure, and underwent left eye cataract surgery 15 years previously. At presentation, her best-corrected visual acuity in the left eye was 0.5, with an intraocular pressure of 23 mmHg. An endocapsular hematoma that partially covered the fundus in the left eye was found. The left eye was observed for 3 months. However, there was no change in the endocapsular hematoma and the discomfort persisted with the position shift; therefore, a vitrectomy, posterior capsulotomy, and anterior chamber irrigation were performed. One month postoperatively, the visual acuity in the left eye was 0.4 and there was no longer a change in the visual acuity with position. Conclusions: A patient with an endocapsular hematoma may have changes in visual acuity with position, and a vitrectomy can be used to treat the endocapsular hematoma. 목적: 체위에 따른 시력 변화를 보인 낭내 혈종 환자를 유리체절제술로 치료한 증례를 보고하고자 한다. 증례요약: 92세 여자 환자로 좌안이 기립 시 잘 보이나 누워있을 시 잘 보이지 않는, 체위에 따른 시력 변화가 있어 내원하였다. 기저질환으로 고혈압, 당뇨, 심부전이 있어 아스피린을 복용 중이었으며 15년 전 좌안 백내장수술을 받은 과거력이 있었다. 내원 시 최대교정시력은 좌안 0.5였으며, 안압은 23 mmHg였다. 전안부 세극등현미경검사상 좌안에서 안저를 일부 가리는 낭내 혈종이 관찰되었다. 3개월간 경과를 관찰하였으나, 낭내 출혈에 변화가 없고 체위에 따른 시력 변화가 지속되어 유리체절제술, 수정체후낭절개술, 전방세척술을 시행하였다. 수술 1달 후 좌안 시력은 0.4였으며 수술 전 호소하였던 체위에 따른 시력 변화는 관찰되지 않았다. 결론: 낭내 혈종 환자는 체위에 따른 시력 변화가 있을 수 있으며, 유리체절제술도 하나의 치료 방법으로 고려해볼 수 있겠다.

Purpose: To compare the surgical success rate of silicone tube intubation according to the preoperative lacrimal syringing test and dacryocystography (DCG) in adult patients with epiphora. Methods: Medical records of 142 patients who underwent silicone tube intubation were retrospectively reviewed. The surgical results were divided into 3 groups based on postoperative symptoms and the syringing test results: Good, Fair, and Fail. Good and Fair were classified into the surgical success groups. We compared the surgical success rate according to the preoperative syringing test and stenosis site observed on dacryocystography. Results: The success rates of silicone tube intubation were 88.4% and 87.4% in eyes with preoperative syringing results of totally- passed and partially-passed syringing tests, respectively, revealing no statistically significant differences (<EM>p </EM>= 0.838, chisquare test). However, in eyes with the preoperative syringing results of partially-passed syringing tests, the success rates were 66.7% in patients with canalicular stenosis, 83.3% in patients with nasolacrimal duct stenosis, and 94.5% in those with diffuse stenosis (<EM>p </EM>= 0.018, chi-square test). Conclusions: No significant differences were found in the success rates of silicone tube intubation according to preoperative syringing test results. However, when considered together with DCG findings, the lowest success rate was found in eyes with the partially-passed syringing test and simultaneously showed canalicular stenosis on DCG. The syringing test results considered with DCG findings may help predict the success rates of silicone tube intubation. J Korean Ophthalmol Soc 2014;55(11):1584-1588
