Purpose: To describe the effect of vitrectomy for the treatment of macular holes associated with proliferative diabetic retinopathy. Methods: Fourteen eyes of 14 patients were chosen among those who had undergone vitrectomy at the Seoul National University Hospital during the last 5 years, due to the presence of a macular hole associated with proliferative diabetic retinopathy. A retrospective study was performed to analyze the fundus findings, pre- and post-operative visual acuity, hole closure status and associated complications. In addition, the study analyzed the results of removing the internal limiting membrane. Results: Twelve out of 14 eyes had proliferative tractional membrane in the macular area. A macular hole with full-thickness was found in 14 eyes (eight eyes before the operation and six eyes during the operation), and final observation showed full hole closure in all 14 eyes. However, eight of the 14 eyes (57.1%) had an improved visual acuity and only two (14.3%) showed an improvement of more than two lines. Seven (77.8%) out of nine eyes that underwent removal of the internal limiting membrane showed visual improvement; no side effects were found in these cases. Conclusions: In our study, we observed that the anatomical features of vitrectomy resulted in the successful treatment of macular holes associated with proliferative diabetic retinopathy. However, limitations still exist in the procedure‘s functional effectiveness for improving visual acuity.

주택품질보증제도 도입을 위한 소비자 및 공급자의 의식조사 연구

박성표(Sung-Pyo Park) 한국주택학회 2006 주택연구 Vol.14 No.3

주택보급률 100%달성 등 주택시장의 여건이 변화하면서 소비자의 주택품질에 대한 욕구는 매우 높아지고 있다. 반면 현행의 주택품질관련 제반 제도는 이러한 시장의 변화에 충분히 대응하고 있지 못하고 있으며, 하자발생에 따른 분쟁이 증가함에 따라 현행제도의 개선 또는 주택품질보증제도 도입에 대한 검토가 필요한 시점이다. 본 연구에서는 주택 소비자 및 공급자의 주택품질에 대한 의식조사를 통해 우리나라 실정에 맞는 주택품질보증제도 도입에 필요한 검토 요인을 도출하고자 하였다. 주요 조사결과를 보면, 먼저 소비자의 주택품질에 대한 만족도는 보통수준보다 약간 높은 것으로 나타났으며, 공급자 규모별로 대형업체가 공급한 주택이 상대적으로 만족도가 높았다. 현행 품질관련 제도에 대한 신뢰도 및 만족도에 있어서는 소비자의 경우 신뢰도 및 만족도가 낮은 반면 공급자는 상대적으로 만족하고 있는 것으로 나타났다. 주택품질보증제도 도입에 대해서는 모두 그 필요성에 대해 강하게 인식하고 있으나, 소비자가 적극적인 반면, 공급자는 상대적으로 소극적인 것으로 나타나 다소 차이를 보였다. 주택품질보증제도 도입에 있어 검토되어야 할 중요항목으로는 소비자와 공급자 모두 합리적인 분쟁처리시스템을 강조하고 있으며, 공급자의 경우 특히 명확한 주택품질기준 마련, 보증기구의 전문성과 공정성이 중요하다는 견해를 나타냈다. 한편 주택의 하자발생 부위는 매우 다양하게 나타나고 있어, 제도시행을 위한 세부적인 검토요인으로 명확한 하자 또는 품질기준이 마련되어야 하며 품질보증의 대상범위가 매우 중요하다는 점을 시사하고 있다. The consumers" interest on housing quality has been increasing due to changes of housing market such as increasing housing supply ratio above 100%. On the other hand the housing quality control system and related regulations fail to respond to these changes properly and it is time to consider the problems of current housing quality system and introduce the home warranty system for settle down the disputes of housing defects. This study tries to draw some critical factors considered for setting up the home warranty system proper to the domestic housing market situation by converging the view point of demanders and suppliers. While the consideration and desire of consumers on the housing quality has increased along housing market situation, there might be improper response of housing quality system to these changes. Among the major findings the consumers" satisfaction on housing quality is found to be slightly above the average level and the satisfaction is a little higher on the big contractors. The satisfaction of suppliers to the current system is good while that of consumers is not. Consumers are more eager to develop the new system of home warranty than the suppliers are, which shows the conflict of interests between two parties. Among the issues in developing the home warranty system both consumers and suppliers emphasize the rational dispute settlement system. The suppliers put more weight on the clear criteria of housing quality and defects and the fairness and expertise of home warranty provider. Also the defects are found to be very diversified and the definition and range of defects is important in considering the home warranty system.

The human retina is a uniquely accessible tissue. Tools like scanning laser ophthalmoscopy and spectral domain optical coherence tomography provide clinicians with remarkably clear pictures of the living retina. While the anterior optics of the eye permit such non-invasive visualization of the retina and associated pathology, these same optics induce significant aberrations that in most cases obviate cellular-resolution imaging. Adaptive optics imaging systems use active optical elements to compensate for aberrations in the optical path between the object and the camera. Applied to the human eye, adaptive optics allows direct visualization of individual rod and cone photoreceptor cells, retina pigment epithelial cells, and white blood cells. Adaptive optics imaging has changed the way vision scientists and ophthalmologists see the retina, helping to clarify our understanding of retinal structure, function, and the etiology of various retinal pathologies. Here we review some of the advances made possible with adaptive optics imaging of the human retina, and discuss applications and future prospects for clinical imaging.

Purpose: We attempt to distinguish the patterns of macular edema due to branch retinal vein occlusion (BRVO) and to find correlations between the 24 hour short-term and three month long-term therapeutic effects of an intravitreal bevacizumab injection. Methods: Forty-four eyes in 44 patients with macular edema due to BRVO underwent an intravitreal bevacizumab injection. Ophthalmoscopic examinations, fluorescein angiographic evaluations, and optical coherence tomography (OCT) examinations performed made before the injections, after 24 hours, and at one, two and three month follow-ups. OCT yielded three patterns of macular edema: diffuse macular edema, cystoid macular edema, and serous retinal detachment. Results: Macular edema significantly improved 24 hours after the injections. The change in central macular thickness after 24 hours had a statistically significant correlation with the three month central macular thickness (Pearson correlation, r=0.757 p=0.011). Cystoid macular edema showed better improvement than the others after 24 hours, but no differences after three months. Conclusions: OCT treatment 24 hours after an intravitreal bevacizumab injection was found to be highly correlated to the long term prognosis. It is therefore useful in determining therapy and predicting the progress of macular edema in patients with BRVO. J Korean Ophthalmol Soc 2010;51(3):379-385

Purpose: To investigate the changes of aqueous vascular endothelial growth factor (VEGF) and interleukin (IL)-6 in patients with acute macular edema secondary to recent-onset branch retinal vein occlusion (BRVO) after a single intravitreal injection of triamcinolone acetonide (IVTA) Methods: Aqueous and plasma levels of VEGF and IL-6 were measured by ELISA in ten controls and thirty patients at the time of IVTA and 3 months afterward. We compared the aqueous levels of VEGF and IL-6 and the clinical course between responders and non-responders. Results: The aqueous levels of VEGF and IL-6 were significantly higher in non-responders than in responders at baseline measurements (495±259 pg/ml vs. 223±110 pg/ml, P<.001; 36±32 pg/ml vs. 16±19 pg/ml, P=.037, respectively). The aqueous levels of VEGF were still higher in non-responders (303±75 pg/ml) 3 months after IVTA, while the aqueous levels of VEGF in responders returned to normal (77±23 pg/ml, P<.001). The aqueous levels of IL-6 normalized in all patients 3 months after IVTA. In non-responders, central foveal thickness was significantly higher, and foveal ischemia and a wide non-perfused area were more common. Conclusions: Non-IL6-dependent VEGF may contribute to persistent or recurrent ischemic macular edema associated with BRVO after IVTA. J Korean Ophthalmol Soc 2008;49(11):1765-1770

Purpose: To report a case of choroidal metastasis of breast cancer that was treated with modified photodynamic therapy. Case summary: A 45-year-old woman visited our clinic with blurred vision of the right eye, which began 1 month before. The patient previously suffered from a low back pain for 1 year. The best corrected visual acuity was 20/20 in both eyes. Fundus examination revealed an elevated yellowish mass-like lesion at the superonasal area in the right eye. Ultrasonography of the right eye showed a highly echogenic choroidal mass with moderate to high internal reflectivity. Fluorescein angiography showed hypofluorescence during the prearterial and arteriovenous phase, and well circumscribed hyperfluorescence during the venous phase. Radiologic examination was performed upon suspicion of metastasis. The examination revealed breast cancer with lung, spine and ovary metastasis. Subsequently, biopsy of the breast mass revealed an invasive ductal carcinoma. Based on these results, the patient was diagnosed with choroidal metastasis from breast carcinoma. The patient received systemic chemotherapy, and modified photodynamic therapy (PDT) was performed on the metastatic choroidal mass. Six days after modified PDT, the mass size was unchanged, and serous retinal detachment developed at the macula and inferior retina. However, 22days after treatment, the mass size markedly decreased and the serous retinal detachment was improved. J Korean Ophthalmol Soc 2010;51(3):458-462

Purpose: To report a case of intralenticular triamcinolone complicated by intravitreal triamcinolone acetonide (IVTA) injection. Methods: A 56-year-old man who presented with lens opacity in the right eye following IVTA injection as a treatment for the central retinal vein occlusion with macular edema was referred to our clinic. Results: The visual acuity in his right eye was hand motion, which was not corrected. A slit lamp examination showed that the intralenticular crystalloid powder in the right eye was likely triamcinolone acetonide. Intralenticular crystalloid powder was detected during the phacoemulsification and the posterior capsule of the lens had been already ruptured. Conclusions: Lens opacity can be complicated by IVTA through intralenticular injection of triamcinolone acetonide.

Purpose: To report a case of bilateral serous retinal detachment associated with Alport’s syndrome that resolved following intensive blood pressure control and electrolyte imbalance correction. Case summary: A 50-year-old male patient presented with bilateral lenticonus and bilateral serous retinal detachment. Bilateral serous retinal detachment with retinal flecks characteristic of Alport’s syndrome appeared along with the development of chronic renal failure and hypertension. The following kidney biopsy revealed Alport’s syndrome. After 14 days, the serous detachment resolved and vision recovered following intensive blood pressure control and electrolyte imbalance correction fundus and FA results were nearly normal. Conclusions: In this case, bilateral serous retinal detachment in Alport’s syndrome resolved with intensive blood pressure control and electrolyte imbalance correction. To the author’s knowledge, this is the first case in South Korea with documentation of the onset and resolution of bilateral serous retinal detachment in Alport’s syndrome.
