  • Background: To assess the normal retina of the pigeon eye using spectral domain optical coherence tomography (SD-OCT) and establish a normative reference. Methods: Twelve eyes of six ophthalmologically normal pigeons (Columba livia) were included. SD-OCT images were taken with dilated pupils under sedation. Four meridians, including the fovea, optic disc, red field, and yellow field, were obtained in each eye. The layers, including full thickness (FT), ganglion cell complex (GCC), thickness from the retinal pigmented epithelium to the outer nuclear layer (RPE-ONL), and from the retinal pigmented epithelium to the inner nuclear layer (RPE-INL), were manually measured. Results: The average FT values were significantly different among the four meridians (p < 0.05), with the optic disc meridian being the thickest (294.0 ± 13.9 ㎛). The average GCC was thickest in the optic disc (105.3 ± 27.1 ㎛) and thinnest in the fovea meridian (42.8 ± 15.3 ㎛). The average RPE-INL of the fovea meridian (165.5 ± 18.3 ㎛) was significantly thicker than that of the other meridians (p < 0.05). The average RPE-ONL of the fovea, optic disc, yellow field, and red field were 91.2 ± 5.2 ㎛, 87.7 ± 5.3 ㎛, 87.6 ± 6.5 ㎛, and 91.4 ± 3.9 ㎛, respectively. RPE-INL and RPE-ONL thickness of the red field meridian did not change significantly with measurement location (p > 0.05). Conclusions: Measured data could be used as normative references for diagnosing pigeon retinopathies and further research on avian fundus structure.

  • A 2-year-old, castrated male, Scottish fold cat was referred to Veterinary Medical Teaching Hospital of Seoul National University (VMTH-SNU) for evaluation of acute bilateral blindness after general anesthesia. For dental prophylaxis in local animal hospital, general anesthesia had been induced with intravenous acepromazine and ketamine, and maintained with isoflurane after intubation. At VMTH-SNU on next day, complete blood count, electrolytes and serum chemistry values were within normal ranges. On neurologic examination, visual placing and postural reactions like as hopping, hemiwalking and wheelborrowing were reduced on right hindlimb. On ophthalmic examination, menace responses were absent on both eyes and pupillary light reflex (PLR) reduced on right eye, but other reflex and fundus were normal. Prednisolone (2 mg/kg sid for 3 days) was administrated orally and tapered. Visual placing was possible on 2nd day, and postural reactions were recovered on 4th day after dental prophylaxis. Based on the process and recovery, this case was considered as postoperative visual loss (POVL) after general anesthesia.

  • Cytomegalovirus (CMV) retinitis is a rare disease, and overlapping manifestations involving the anterior segment are extremely uncommon. We report a patient who initially presented with persistent corneal edema and was later diagnosed with CMV retinitis. A 72-year-old man with uncontrolled intraocular pressure (IOP) in his right eye visited a tertiary hospital. At initial presentation, the IOP was 36 mmHg and the fundus was not clear due to corneal edema. Spectral domain optical coherence tomography revealed paracentral acute middle maculopathy (PAMM). Panretinal obstructive vasculopathy was observed on ultra-widefield fluorescein angiography. Three weeks later, trabeculectomy was performed to resolve the persistently high IOP. Once corneal edema improved, a white patch-like peripheral lesion and silver wire-like retinal vasculature were observed. Polymerase chain reaction of the aqueous humor was positive for CMV. Oral valganciclovir and intravitreal ganciclovir were administered as antiviral therapies. Despite treatment for 4 months, the final visual acuity was no light perception, with persistent corneal edema and neovascularization of the iris. We describe a rare case of the simultaneous occurrence of hypertensive uveitis and CMV retinitis. The presence of PAMM could be an initial identifiable sign of CMV retinitis, even in the presence of media opacity.

  • 이 글은 사회문제 해결형 기술개발사업에서 진행된 리빙랩 활동을 검토하고 그 의의와 과제를 분석하고자 한다. 분석 사례는 2014년에서 2015년에 과학기술정보통신부(구 미래창조과학부)가 추진한 사회문제 해결형 기술개발사업 중 대표 사례인 '안저카메라 기술개발'과 '보행자 자동감지 시스템 개발'을 대상으로 한다. 분석 결과 두 사례 모두 리빙랩 방법론을 활용하여 기술개발부터 실용화 단계까지 사용자 참여형 연구개발 구조로 설계되었다. 즉 리빙랩은 최종 사용자의 지속적인 상호작용을 통해 최종 수요를 구체화하고, 제품과 서비스를 개선 실증할 수 있는 있는 하부구조로 기술-제품-서비스를 진화시키는 시스템으로 작동하였다. 1차 시도된 단계이나, 그 과정에서 최종 수혜자인 국민의 관점을 반영하면서 R&D 성과를 확산시키고 새롭게 일하는 방식을 만드는 계기를 만들어내고 있다. 향후 리빙랩이 확대되기 위해서는 중앙정부 및 지자체의 명확한 문제 인식과 일하는 방식의 변화가 필요하다. 또한 최종사용자, 매개사용자, 기업, 시민사회 등 관련 주체의 적극적인 참여 및 조직화를 필요로 한다. 현재 리빙랩 활동은 소수의 전문가가 의제를 주도하고 있기 때문에 다양한 리빙랩 실험과 함께 시행착오를 통한 학습 체계의 구축이 중요한 과제이다. 또한 현장지향성 문제해결을 위해서는 일반시민 담당 공무원을 포함한 과학기술자, 정책 전문가, 현장 활동가 등을 포함하는 다학제 초학제 연구팀의 구성과 운영이 필수적이다.

  • Objectives: Considering high prevalence of myopia in Asian countries, social cost paid for myopia may gradually increase in Korea. However, studies for developing myopia treatment are deficient. The study was to evaluate whether the periocular acupressure with a medical massager is effective for suppressing myopia progression. Methods: This study was an investigator-sponsored, prospective, open-labeled, and superiority pre and post single-armed study. 14 myopia children aged 7-12 years wore a medical massager for 15 minutes to stimulate periocular acupoints. For 24 weeks, the participants used the device twice a day. Based on prior studies, the refraction change of naturally proceeded myopia was set as -0.38 D. The axial length change of naturally proceeded myopia was set as 0.228 mm. To assess the safety, we performed vital sign check, physical examination, visual acuity test, slit lamp examination, IOP measurement, and fundus examination. Results: The refraction and axial length of the participants increased. For 24 weeks, the change in refraction was -0.38 D at the right eye and -0.40 D at the left. The change in axial length was 0.21 mm at the right and 0.22 mm at the left. In the safety assessment, any adverse event did not occur. Conclusions: There was no significant difference between the control group and the intervention group. The effect of growth may have more contributed to our result than that of acupressure. Based on our result, a full-scale study will not be conducted.

  • The objective of this retrospective study was to investigate the prevalence of retinal diseases in dogs presented to the Veterinary Medical Teaching Hospital, Seoul National University from April 2004 to December 2005. Sixty-five dogs (120 eyes) with retinal diseases involving blindness were included in this study. Age, breed, and gender data for all breeds were collected from medical records documenting vision loss. Generalized progressive retinal atrophy (gPRA) was the most common manifestation. Other prevalent findings included sudden acquired retinal degeneration (SARD) and retinal detachment (RD). Bilateral gPRA was found in 32 dogs with a female-to-male ratio of 1 : 1. The mean $age{\pm}SD$ of all dogs in this group was $4.66{\pm}2.30$ years with a range of 3 to 12 years. Breeds with highest prevalence of gPRA were Miniature Schnauzer (24/32, $mean{\pm}SD$ age: $3.79{\pm}0.78$ yr) and Poodle (2/32, $6.50{\pm}0.71$ yr). Twelve dogs (24 eyes) were diagnosed with SARD bilateraly, ranging from 3 to 13 years of age ($mean{\pm}SD:\;6.91{\pm}2.61$ yr). There were no abnormalities in fundus of 11 dogs at presentation. Electroretinography (ERG) without anesthesia was performed in 7 dogs, and all response was totally extinguished. Retinal detachment was identified in 21 dogs (32 eyes): 11 bilateral and 10 unilateral (7 right eye, 3 left eye). The most common breed was Shih Tzu (15/21, $mean{\pm}SD$ age: $4.39{\pm}3.24$ yr). Four other breeds comprised the remaining 6 cases (8 eyes). The everall mean age of the group was: $4.18{\pm}2.89$ years (range 0.8 to 14 years) with a female-to-male ratio of 1 : 1.1 (10 females, and 11 males).
