PURPOSE: We report a case of utilizing a previous silicone band track in the reoperation of scleral encircling. CASE SUMMARY: An 8-year-old male presented with rhegmatogenous retinal detachment in the right eye. Five days after this diagnosis, he received scleral buckling surgery and cryopexy to seal the retinal tear. One month after surgery, a fundus examination showed subretinal fluid at the inferior site of the scleral buckle. He underwent scleral encircling surgery and a cryopexy procedure. The patient has had an uneventful postoperative course, and the retina has remained attached over a follow-up period of 9 months. However, exotropia and hypotropia developed in the right eye. Diagnosis of restrictive strabismus due to tissue adhesion around the silicone band was made. The encircling band was therefore removed and laser photocoagulation was performed 360° around the retina. Twenty-four hours after surgery, a fundus examination showed subretinal fluid. He received 360° scleral encircling surgery not using the 360° conjunctival peritomy. After confirming a previous encircling tract using #0-0 polydioxanone as a guide, #5-0 Nylon was tied to the end of the guide and inserted through the encircling tract with the end sutured with the silicone band. The silicone band was inserted into the encircling tract by pulling the #5-0 Nylon as a guide. Ophthalmoscopy revealed an attached retina with indentation of the scleral buckle at 360°. CONCLUSIONS: For reoperation in patients who previously underwent scleral encircling surgery, using the previous scleral encircling tract may be effective in cases with conjunctival and tissue adhesion.

PURPOSE: To compare parameters of confocal scanning laser ophthalmoscopy (Heidelberg Retinal Tomograph [HRT] II) in high myopia with age- and sex-matched emmetropes. METHODS: A hospital-based cross-sectional study was conducted among Nepalese subjects aged 18 to 35 years at BP Koirala Lions Centre for Ophthalmic Studies, Institute of Medicine, Maharajgunj, Kathmandu from November 2015 to October 2016. Fifty consecutive subjects with high myopia (spherical equivalent ranging from −6.00 to −12.00 diopters) and age- and sex-matched emmetropic subjects were enrolled for comparison. Correlations between disc area and other HRT parameters, asymmetry between the right and left eyes, and comparisons between male and female subjects in both high myopic and emmetropic groups were evaluated. RESULTS: Disc area was not significantly (p = 0.11) larger in high myopic eyes than in emmetropic eyes. HRT parameters in highly myopic eyes involved smaller cup parameters and greater rim parameters compared with emmetropic eyes. Disc area was found to be significantly positively correlated with inter disc parameters and significantly negatively correlated with rim to disc area ratio in the high myopia group. Disc area and other intra-disc parameters showed significant correlations between right and left eyes in both high myopia and emmetropia, and no significant differences between males and females from a Nepalese population. CONCLUSIONS: Characteristics of HRT parameters in high myopic eyes involved smaller cup parameters and greater rim parameters compared with emmetropic eyes in a Nepalese population. The effect of disc area on HRT parameters differed significantly only in height variation contour by emmetropic eyes.

PURPOSE: We detected retinal nerve fiber layer (RNFL) defects using a confocal scanning laser ophthalmoscopy (CSLO) with both blue and green laser sources and evaluated image quality based on laser wavelength. METHODS: This was a retrospective observational case study. Blue and green CSLO images of 181 eyes with suspected glaucoma were evaluated and compared. Three independent observers identified the presence of RNFL defects and determined which CSLO imaging source provided superior visibility of the defect. After assessing the defect imaging by laser source, demographics and image quality indices of optical coherence tomography between blue better and green better groups were analyzed. RESULTS: Both blue and green CSLO showed high discriminating ability for RNFL defects. The discriminating ability of blue CSLO was significantly greater than that of green CSLO (p = 0.004). Among eyes with a detectable RNFL defect, 61.8% were better visualized with the blue laser compared to the green laser. Compared with the blue better group, the green better group was significantly older (p = 0.009), had a greater proportion of females (p = 0.005), had poorer best-corrected visual acuity (p = 0.001), more severe cataracts (p = 0.001), lower signal strength (p = 0.003), and poor image quality indices (p = 0.001). CONCLUSIONS: Both blue and green CSLO imaging was useful for detecting RNFL defects, but blue CSLO was superior to green CSLO in quality of RNFL defect imaging in most patients with clear media.

PURPOSE: To evaluate the clinical usefulness, convenience, and possibility of using the medical records of fundus photography with a smartphone. METHODS: We used an ophthalmoscope to examine the images using a smartphone (iphone 6, Apple Inc., Cupertino, CA, USA) and +20D and +28D condensing lenses. Twenty-four subjects were selected for comparison with the conventional funduscopic camera. The posterior pole of the 45° range of the right eye and the fundus photograph taken using the smartphone were analyzed. We measured the distances between specific points on three photographs taken of the patient and calculated the photographing range. RESULTS: The +20 D lens was 0.80 ± 0.06 times smaller than that of the fundus camera and +1.12 ± 0.06 times bigger than that of the fundus photograph. When the area of the funduscope was converted to 45°, +20 D could visualize an area of 36.10 ± 2.82°, and +28 D could visualize a 50.56 ± 2.68° area. CONCLUSIONS: Without expensive equipment, a smart phone and a condensing lens can be used to easily perform fundus examination without the need for a special technique. Therefore, this technique is not only useful clinically, but also is very convenient for keeping medical records as fundus photographs.

PURPOSE: The purpose of this study was to understand the situation of diabetes patients receiving examinations for diabetes complications and to explore the factors influencing their intention to receive examinations for diabetes complications. METHODS: A cross-sectional study was performed that included 251 diabetes patients who visited outpatient clinics in Southern Taiwan. A survey using a self-administered questionnaire was conducted from October 2015 to January 2016. The questionnaire included items on demographic characteristics, perceived susceptibility to diabetes complications, perceived seriousness of diabetes complications, perceived benefits of taking action to receive diabetes complication examinations, perceived barriers to taking action to receive diabetes complication examinations, and the intention to receive diabetes complication examinations. The data were analyzed using regression analysis. RESULTS: The percentage of participants who received fundus, foot, and kidney examinations was 67.7%, 61.4%, and 73.3%, respectively. Every point increase on the perceived barriers to taking action to receive diabetes complication examinations scale increased the intention to receive a foot examination in the following year by 0.91 times (p = .002), and every point increase on the perceived susceptibility to diabetes complications scale increased the intention to receive a kidney examination in the following year by 1.19 times (p = .045). CONCLUSIONS: Nurses should shoulder the responsibility to increase patients' intention to receive examination of diabetes complications. The results of this study can be used to promote nurses' care efficacy in preventing diabetes complications. They can also provide medical institutions with information to establish prevention and control policies for diabetes complications.

PURPOSE: We report a case of amaurosis fugax associated with ipsilateral internal carotid artery agenesis. CASE SUMMARY: A 50-year-old woman presented with amaurosis fugax in her left eye; the frequency of episodes of the condition had recently increased to once a month. She had a history of hypertension and dyslipidemia, and was under medical therapy. The visual acuity of both eyes was 20/20. Slit-lamp examination was normal except for pseudophakia. Ophthalmoscopy revealed a myopic tigroid fundus and a myopic tilted disc. No abnormalities were evident in fluorescein fundus angiography. Brain computed tomography showed that the left bony carotid canal was absent, and magnetic resonance angiography showed that the left internal carotid artery was also absent. She was diagnosed with left internal carotid artery agenesis. Other neurological and hematological parameters were within normal ranges. The amaurosis fugax spontaneously disappeared and has not recurred over the past 12 months. Our case, although rare, suggests that amaurosis fugax may be associated with internal carotid artery agenesis.

PURPOSE: To compare clinical, angiographic, and optical coherence tomographic characteristics between eyes with acute Vogt-Koyanagi-Harada (VKH) disease and eyes with acute bilateral central serous chorioretinopathy (CSC), and to demonstrate distinguishing features between the two diseases in confusing cases. METHODS: The medical records of 35 patients with VKH disease and 25 patients with bilateral CSC were retrospectively reviewed. Characteristics according to slit-lamp biomicroscopy, ophthalmoscopy, fundus photography, fluorescein angiography, indocyanine green angiography, and spectral-domain optical coherence tomography were compared between the two diseases. RESULTS: Five of 35 patients (10 of 70 eyes, 14.3%) with VKH disease were initially misdiagnosed as CSC patients, and six of 25 patients (12 of 50 eyes, 24%) with bilateral CSC were initially misdiagnosed as patients with VKH disease. Pigment epithelial detachment in CSC and optic disc hyperemia in VKH disease show the highest positive predictive values of 100% for each disease. CONCLUSIONS: Optic disc hyperemia in VKH disease and pigment epithelial detachment in bilateral CSC are the most specific clinical manifestations of each disease at initial patient presentation.

A 53-year-old Asian woman was treated with hydroxychloroquine and chloroquine for lupus erythematosus. Within a few years, she noticed circle-shaped shadows in her central vision. Upon examination, the patient's visual acuity was 20 / 25 in both eyes. Humphrey visual field (HVF) testing revealed a central visual defect, and fundoscopy showed a ring-shaped area of parafoveal retinal pigment epithelium depigmentation. Fundus autofluorescence imaging showed a hypofluorescent lesion consistent with bull's eye retinopathy. Adaptive optics scanning laser ophthalmoscope (AO-SLO) revealed patch cone mosaic lesions, in which cones were missing or lost. In addition, the remaining cones consisted of asymmetrical shapes and sizes that varied in brightness. Unlike previous studies employing deformable mirrors for wavefront aberration correction, our AO-SLO approach utilized dual liquid crystal on silicon spatial light modulators. Thus, by using AO-SLO, we were able to create a photographic montage consisting of high quality images. Disrupted cone AO-SLO images were matched with visual field test results and functional deficits were associated with a precise location on the montage, which allowed correlation of histological findings with functional changes determined by HVF. We also investigated whether adaptive optics imaging was more sensitive to anatomical changes compared with spectral-domain optical coherence tomography.
