ABSTRACT
Purpose: To analyze the imaging characteristics and the clinical course of patients showing concomitant paracentral acute middle maculopathy (PAMM) and acute macular neuroretinopathy (AMN) post?blunt trauma. Methods: PAMM and AMN lesions post?blunt trauma diagnosed on enhanced depth imaging optical coherence tomography (EDI?OCT) were recruited for the study. Results: Thirteen eyes of 13 individuals with a history of blunt trauma were included in the study, of whom 11 (85%) were males. Mean age of the patients was 33.62 (range 16–67) years. Mean visual acuity at presentation and the last visit was 1.67 log of minimum angle of resolution (logMAR) and 0.82 logMAR, respectively. Mean interval between trauma and imaging was 5.08 (range 1–15) days. All patients had unilateral involvement, with the right eye being involved in 10 patients (77%). All patients had concomitant PAMM and AMN lesions. Conclusion: Presence of coincident PAMM and AMN suggests a common pathophysiologic etiology, but the description of concomitant PAMM and AMN in the setting of blunt trauma to eye is hitherto unreported. Identifying AMN in a setting of PAMM requires meticulous examination of the OCT and OCTA images. It can be a cause of suboptimal visual recovery in such eyes.
ABSTRACT
AIM: To compare the differences in choroidal structure between hyperopic amblyopia and normal children of the same age by the enhanced depth imaging optical coherence tomography(EDI-OCT)technique.METHODS: There were 35 cases in 50 eyes of children with hyperopic amblyopia visiting our hospital in January 2021 to December 2021 selected in the amblyopic group, and 30 cases in 51 eyes of healthy children who matched general data in the same period were selected in the control group. EDI-OCT examination was performed to measure the choroidal thickness(CT). After image processing, the total choroidal area(TCA), luminal area(LA), stromal area(SA)and choroidal vascularity index(CVI)were obtained.RESULTS: TCA(except inferior quadrant), SA(except inferior quadrant of the outer ring), LA and CT(except inferior and temporal quadrant )in the amblyopic group of each area were significantly larger than that in the control group(P<0.05), and there was no significant difference in CVI between the two groups except the temporal quadrant of the outer ring(P>0.05). There was no significant difference in CT for all degrees of hyperopic amblyopia, with the exception of the nasal quadrant(P>0.05).CONCLUSION: Hyperopic amblyopia is accompanied with abnormal choroidal structure. As the degree of hyperopia increases, TCA, LA and SA exhibit increasing trends. The changes in choroidal structure are presumed to be related to hyperopic amblyopia.
ABSTRACT
@#AIM: To compare the difference of choroidal delamination thickness in macular fovea between patients with early active Graves ophthalmopathy and healthy subjects by optical coherence tomography(OCT)enhanced deep imaging.<p>METHODS:From December 2017 to May 2019, patients with early active Graves ophthalmopathy diagnosed in our hospital(GO group)and 31 patients(62 eyes)with age and sex matched healthy physical examination(control group)were selected. Diopter, best-corrected visual acuity(BCVA), intraocular pressure, exophthalmos, EDI-OCT and other examinations were performed on all the subjects. The differences of macular central concave choroidal thickness(SFCT), choroidal macrovascular layer thickness(LCVT)and choroidal capillary layer/middle vascular layer thickness(MCVT)between the two groups were compared.<p>RESULTS: There was no significant difference in equivalent spherical lens power, BCVA and eye axis between the two groups. However, the IOP(17.22±2.67mmHg), exophthalmos(15.44±0.92mm), SFCT(315.79±14.99μm), LCVT(234.66±14.90μm)in GO group were significantly higher than those in control group(13.35±1.54mmHg, 12.90±1.00mm, 239.00±12.67μm, 159.16±13.30μm)(all <i>P</i>Symbol|@@0.05), but there was no significant difference in MCVT between the two groups(81.13±7.46μm <i>vs</i> 80.13±7.63μm, <i>P></i>0.05).<p>CONCLUSION: SFCT and LCVT in patients with early active Graves ophthalmopathy are thickened, and MCVT has no obvious change, suggesting that EDI-OCT measurement of SFCT and LCVT has certain reference value for evaluating early active Graves ophthalmopathy.
ABSTRACT
@#AIM: To investigate the retinal thickness, choroidal thickness and optic disc nerve fiber layers thickness in high myopia amblyopia eyes and high myopia eyes with the similar diopter by using enhanced depth imaging optical coherence tomography(EDI-OCT).<p>METHODS:Nineteen Chinese children, 26 eyes were recruited. Those patients were divided into high myopia amblyopia group(11 eyes)and high myopia group(15 eyes). The thickness in the retina and choroid in different regions, as well as the thickness of optic disc nerve fiber layer were measured by EDI-OCT.<p>RESULTS: The retinal thickness at the 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm to the fovea, in most directions, retinal thicknesses were statistically different between the two groups(<i>P</i><0.05). At the 3.0mm inferior to the fovea, the choroidal thickness in high myopia amblyopia was significantly thinner than high myopia(<i>P</i>=0.012). In the optic disc nerve fiber layer, there was no statistical difference between high myopia amblyopia and high myopia(<i>P</i>>0.05).<p>CONCLUSION: In the same diopter range, the retinal thickness around the fovea in the high myopia amblyopia was significantly thinner than high myopia, and the occurrence and development of amblyopia may be involved in its change process.
ABSTRACT
Objective To observe the efficacy and safety of conbercept in the treatment of central serous chorioretinopathy (CSC) by EDI-OCT.Methods From July 2015 to July 2017,42 patients (44 eyes) of central serous choriodal retinopathy received intravitreal injection of conbercept (0.5 mg,0.05 mL).Then,the best corrected visual acuity was recorded before injection and 1 week,4 weeks and 12 weeks after treatment;meanwhile,EDI-OCT was used to measure subfoveal choroidal thickness at different time points.Results In CSC patients,the BCVA of 1 week,4 weeks and 12 weeks after treatment were 0.57 ±0.23,0.62 ±0.23 and 0.59 ±0.71,respectively,which were significantly higher than those before treatment [(0.43 ± 1.11)] (all P ＜ 0.05).The subfoveal choroidal thickness was (308.17 ± 16.52) μm,(286.54 ± 37.52) μm and (274.58±41.38)μm at 1 week,4 weeks and 12 weeks after treatment,respectively,which were significantly lower than those before treatment [(346.31 ± 59.43) μm] (all P ＜ 0.05).Conclusion It is safe and effective for conbercept injection in the treatment of CSC.
ABSTRACT
Propósito: describir los hallazgos y la medición del grosor coroideo subfoveal utilizando tomografía óptica coherente de imagen de profundidad mejorada (EDI OCT), en paciente hispanos con sospecha clínica de atrofia coroidea relacionada con la edad (ARCA). Métodos: estudio descriptivo y trasversal en 17 pacientes con impresión clínica de ARCA, basados en: disminución de la agudeza visual de reciente aparición, alteraciones pigmentarias en la macula, apariencia de fondo de ojo atigrado y atrofia peripapilar a pesar de no ser miope. A todos se les realizó examen oftalmológico completo, que incluía: Agudeza visual mejor corregida (BCVA), biomicroscopía con lámpara de hendidura y evaluación del fondo de ojo bajo dilatación. A estos pacientes se les realizó fotografía digital del fondo de ojo y tomografía óptica coherente de imagen de profundidad mejorada (EDI OCT). Se realizó un total de 5 mediciones del grosor coroideo en el área macular en cada ojo. Resultados: se evaluaron 26 ojos de 14 pacientes, con una edad media de 70,86 años (DS± 8,46 años). El 57.14% fueron mujeres y el 42.86% hombres. El promedio de la agudeza visual fue 20/47 (0,38 LogMAR), el 80.2% presentaron manifestación binocular. La media del grosor coroideo fue 119,53 µm (DS±49,68µm). No hubo correlación estadísticamente signifi cativa entre la BCVA y grosor coroideo (P=0.407). Conclusión: la atrofia coroidea relacionada con la edad es una condición que puede presentarse en pacientes hispanos de edad avanzada. Afecta igualmente a hombres y mujeres, es usualmente bilateral y el grado de adelgazamiento de la coroides no predice la agudeza visual final.
Purpose: to describe the findings and measure the subfoveal choroidal thickness with Enhanced Depth Imaging (EDI) OCT in hispanics subjects with clinical impression of age-related choroidal atrophy (ARCA). Methods: a descriptive and cross-sectional study of 17 subjects with clinical impression of ARCA: based on recently decreased visual acuity, pigmentary alterations in the macula, a tessellated fundoscopic appearance, and peripapillary atrophy despite being not myopic. All patients had a comprehensive ocular examination, including BCVA, biomicroscopic and fundus examination. They underwent color fundus photography and EDI OCT. A total of 5 measurements were took of each eye. Results: twenty six eyes were included from 14 patients, with a mean age 70,86 years (SD ± 8,46 years). The 57,14% were female and 42.86% male. The mean visual acuity was 20/47 (0,38 LogMAR Equivalent), 80.2% had bilateral disease. The mean choroidal thickness was 119,53 µm (SD ± 49,68 µm). There was no statistically significant correlation between BCVA and choroidal thickness (p =0,407). Conclusions: the ARCA is a condition that can be present in elderly Hispanics subjects. Affects equally male and female, it is usually bilateral and the degree of choroidal thinning does not predict the final visual acuity.
