Toxocariasis is one of the most common geohelminth infections in several parts of the world. We describe a rare case of ocular toxocariasis with secondary exudative retinal detachment treated with albendazole and an intravitreal dexamethasone implant. A 13-year-old boy with counting finger vision was diagnosed with retinal vasculitis and exudative retinal detachment in his right eye. Fundoscopic examination revealed retinal hemorrhage, retinal vasculitis, and exudative retinal detachment. Serological test using serum and intraocular aqueous humor were positive for anti-Toxocara specific IgG antibodies. He received repeated doses of intravitreal dexamethasone implants combined with oral albendazole. A sequential follow-up optical coherence tomography revealed that the retina was successfully reattached. His visual acuity subsequently improved to 20/400.

Cataract and Retinal detachment eyes dogs were examined by ultrasonography. Ultrasonography of the immature and mature cataractous eyes showed echographic changes, and cataractous lens increased in thickness. The diagnosis of retinal detachment was made an echodense waving motion structure in the posterior segment was imaged. This investigation will provide basic information for the study of pathologic conditions affecting the eyes of dog using ultrasound unit commonly available to the veterinarian.

Objectives: Lifting heavy weights involves the Valsalva manoeuvre, which leads to intraocular pressure spikes. We used data from a case-control study to further investigate the hypothesis that occupational lifting is a risk factor for retinal detachment. Methods: The study population included 48 cases (patients operated for retinal detachment) and 84 controls (outpatients attending an eye clinic). The odds ratios (OR) of idiopathic retinal detachment were estimated with a logistic regression model (adjusted for age, sex and body mass index). Three indexes were used to examine exposure to lifting; 1) maximum load lifted, 2) average weekly lifting, 3) lifelong cumulative lifting. Results: For all indexes, the most exposed subjects showed an increased risk of retinal detachment compared with the unexposed (index 1: OR 3.57, 95% confidence interval [CI] 1.21-10.48; index 2: OR 3.24, 95% CI 1.32-7.97; index 3: OR 2.23, 95% CI 1.27-8.74) and dose-response relationships were apparent. Conclusion: These results reinforce the hypothesis that heavy occupational lifting may be a relevant risk factor for retinal detachment.

본 연구는 망막박리에서 실리콘 기름주입술에 대한 임상적 결과를 분석한 것이다. 1999년부터 2002년까지 유리체절제술과 실리콘기름 주입술를 받은 44명 환자의 45안을 연구하였다. 결과는 다음과 같다. 1. 유리체절제술 후 시력이 두 줄 이상 호전된 경우는 45안 중 24안(53%)이었으며, 45안 중 18안(40%)에서는 시력의 변화가 없었다. 2. 실리콘기름 주입술 후 16안(6.3%)에서 실리콘기름을 제거하였으며 그 중 1안에서 망막박리가 재발되어 실리콘기름 재주입술을 시행하여 망막재유착을 이루었다. 3. 재수술을 포함하여 해부학적인 재유착은 45안 중 44안(97%)에서 이루었다. 4. 실리콘기름주입 후 발생한 합병증은 백내장(16안), 녹내장(10안), 실리콘기름의 유화(5안), 각막병증(2안), 재발성 망막박리 (1안)이었다. 결론적으로 망막박리 환자에게 일차수술로 유리체 절제술 후 유리체 대용물로 실리콘 기름을 사용하는 것은 여러 합병증의 발생에도 불구하고 높은 해부학적 성공률과 시력 개선효과를 보여주었다.

Pregnancy-related ocular diseases develop mostly in the third trimester of pregnancy. Here, we describe a case of a pregnant woman with a choroidal mass that caused a serous retinal detachment during the first trimester of pregnancy. The patient's condition resolved spontaneously after an abortion.

목적: 유리체절제술을 시행받은 열공망막박리 환자에서 수술 당일 발생한 맥락막상강출혈 1예를 보고하고자 한다. 증례요약: 60세 여자 환자가 1주일 전부터 시작된 좌안 비문증과 광시증, 시력저하를 주소로 내원하였다. 좌안의 최대교정시력은 0.1이었고, 안저검사에서는 황반부를 침범하고 상이측 열공을 동반한 망막박리가 관찰되었다. 전신마취하에 좌안 백내장수술과 23 G 무봉합 유리체절제술, 14% C3F8 가스충전술을 시행하였다. 마취 회복 1시간 뒤 환자는 갑자기 극심한 좌안의 통증을 호소하였고, 압박안대 제거 후에 측정한 안압은 58 mmHg로 높았다. 통증은 10분 이내에 저절로 호전되었으며 다시 측정한 안압은 8 mmHg였다. 안저검사에서 맥락막상강출혈을 시사하는 적갈색의 융기된 병변이 관찰되었다. 압박안대를 한 채 엎드린 자세를 취하도록 하였고, 수술 다음 날에는 공막절개부위를 통한 출혈이 관찰되었다. 이후 출혈성 맥락막박리는 악화 소견 없이 지속적으로 감소하였으며 술 후 3주째에는 유리체강 내 100% C3F8 가스주입술을 추가 시행하였다. 술 후 3개월째 좌안 교정시력은 0.8로 호전되었고 망막은 유착된 상태로 안정적이었다. 결론: 유리체절제술 후 심한 안구통을 호소하는 경우에 맥락막상강출혈을 의심하는 것이 필요하다.

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).

This study was performed to describe the outcome of pars plana retinopexy with perfluoro-n-octane (PFO)-silicone oil (SiO) exchange in dogs with rhegmatogenous retinal detachment in Seoul National University Veterinary Medical Teaching Hospital (SNU VMTH) from 2014 to 2017. Nine eyes of 8 dogs were included in this study. Medical records including signalment, history, duration from onset of blindness to surgical intervention, pre-operative findings, duration from surgery to regaining vision, and post-operative complications were evaluated. No eyes were visual before surgery. Duration from onset of blindness to surgical intervention was 2-30 days (median 8 days); duration from surgery to regain vision was 1-14 days (median 6 days); follow-up time was 15-1088 days (median 69 days). Post-operative complications were divided as temporary vs permanent conditions. Temporary complications were corneal ulcer, uveitis, retinal haemorrhage, glaucoma, subconjunctival leakage of SiO, and vitreal haemorrhage. Permanent complications were anterior chamber migration of SiO, retinal degeneration, corneal degeneration, re-detachment, and cataract. Six of 9 eyes regained functional vision, five of which remained visual throughout the follow-up time while the other one lost vision after 3 months because of uveitic glaucoma. In conclusion, pars plana retinopexy with PFO-SiO exchange provided fair outcome in 66.7% cases described in this study.

목적: 증상이 있는 후유리체박리 환자에서 망막열공을 진단하기 위한 초광각안저촬영기의 눈방향전환 촬영술의 유용성을 알아보고자 하였다. 대상과 방법: 비문증 또는 광시증으로 내원하여 후유리체박리를 진단받은 환자의 의무기록을 후향적으로 조사하였다. 초광각안저촬영술의 눈방향전환 촬영 사진 4장을 이용하여 독립적으로 망막열공을 확인하였고, 눈방향전환 초광각안저촬영술의 망막열공 진단에 대한 민감도와 특이도를 구하였다. 결과: 총 94명의 94안이 연구에 포함되었다. 산동 후 시행한 안저검사에서 42안(45%)이 망막열공을 진단받았다. 망막열공 진단에 대한 눈방향전환 초광각안저촬영술의 민감도는 98% (95% 신뢰구간 88-100%), 특이도는 98% (95% 신뢰구간 90-100%)였다. 전체 망막열공 58개 중에 눈방향전환 초광각안저촬영술에서 상측 28개(97%)와 하측 10개(100%), 비측 6개(100%), 이측 13개(100%)의 망막열공이 확인되었다. 결론: 눈방향전환 초광각안저촬영술은 증상이 있는 후유리체박리 환자에서 망막열공을 진단하는 데 유용하다. 그렇지만 모든 증례에서 산동 후 안저검사를 대체할 수는 없었다.
