  • Clinical observation of multifocal choroiditis

    Objective To investigate the clinical features of multifocal choroiditis (MC) and guide the diagnosis and treatment. Methods Retrospective analysis of clinical data of 18 MC cases (28 eyes) who were diagnosed through fluorescein angiography (FFA) or indocyanine green angiography (ICGA) and fundus characteristics. Results Multiple round to oval lesions scattered throughout the posterior pole and peripheral areas of ocular fundi of all of the 28 eyes(binocular in 10 and monocular in 8) were found. Active focal lesions of ocular fundi were seen in 8 patients and inactive lesions in 10 patients. active and 10 cases were inactive. Choroidal neovascularization(CNV) in macular area was found in 7 patients. The images of FFA of the legions showed hypofluorescence in the early phase, with late leakage and gradual staining or window is defect in the late phase. Conclusions MC is a rare disease and often misdiagnosed to other disease and FFA helpful in diagnosis. (Chin J Ocul Fundus Dis, 2005, 21: 367-370)

  • The effect of internal boundary membrane detachment on visual acuity in the affected side of non-arteriotic central retinal artery occlusion

    Objective To observe the clinical and imaging features of non-arteriotic central retinal artery occlusion (NA-CRAO) with internal boundary membrane detachment (ILMD), and to analyze its relationship with visual prognosis. MethodsA retrospective clinical study. A total of 88 patients with NA-CRAO hospitalized in Department of Ophtalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) from January 2014 to June 2023 were included in the study. Best corrected visual acuity (BCVA), optical coherence tomography (OCT) and fluorescein fundus angiography (FFA) were performed. The BCVA test used the international standard visual acuity chart, which was statistically converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity. OCT observed the presence of ILMD and the thickening of the inner retina and the disappearance of anatomical stratification. FFA recorded arm-retinal circulation time (A-Rct) and retinal arterion-distal filling time (FT), and observed ciliary retinal artery, fluorescein retrograde filling, cotton spots, luciferin nodal filling, macular non-perfusion, capillary fluorescein leakage, optic disc strong fluorescence, choroidal background weak fluorescence and other characteristics. According to whether there was ILMD, the patients were divided into ILMD group and non-ILMD group, with 44 cases and 44 eyes respectively. The two groups received the same treatment. The follow-up time was 30 days after treatment. The clinical, FFA characteristics and BCVA before and after treatment were compared between the two groups. t-test was used for comparison between groups. ResultsIn ILMD group and non-ILMD group, there were 43 cases of male and 1 case of female, respectively, and the proportion of male was significantly higher than that of female. Before and after treatment, the logMAR BCVA of ILMD group and non-ILMD group were 2.35±0.42, 2.01±0.46, 1.47±0.60, 0.77±0.49, respectively. There were significant differences in logMAR BCVA between the two groups before and after treatment (t=8.025, 12.358; P<0.001). Before treatment, A-Rct and FT in ILMD group were longer than those in non-ILMD group, and the difference was statistically significant (t=3.052, 3.385; P<0.05). After treatment, there was no significant difference (t=1.040, 1.447; P>0.05). The proportion of ciliary retinal artery and cotton plaque in ILMD group was lower than that in non-ILMD group. There was no significant difference in ciliary retinal artery between the two groups (χ2=-0.961, P>0.05), but there was a significant difference in cotton wool plaque between the two groups (χ2=-3.364, P<0.05). Compared to the non-ILMD group, The proportion of retrograde fluorescein filling in retinal artery (χ2=-2.846), segment filling (χ2=-3.907), macular non-perfusion (χ2=-6.656), capillary fluorescein leakage (χ2=-4.367), optic disc strong fluorescence (χ2=-3.525) and choroidal background weak fluorescence (χ2=-2.276) increased, the difference was statistically significant (P<0.05). ConclusionsIn patients with NA-CRAO, compared with those without ILMD, those with ILMD have more severe retinal ischemia and worse BCVA before and after treatment. ILMD is one of the poor prognostic markers of NA-CRAO vision.

  • 脉络膜皱褶

    脉络膜皱褶是指视网膜下明暗相间的条纹,荧光素眼底血管造影主要表现为与视网膜血管不相干的条带状弱荧光,相应之处在吲哚青绿血管造影晚期则表现为强荧光条带,光相干断层扫描检查可见视网膜色素上皮、Bruch膜、脉络膜毛细血管层以及视网膜神经上皮均出现波纹样改变。脉络膜皱褶不是一个独立的疾病,而是很多眼病的一个眼底表现。可发生于球内或球后肿瘤、低眼压、后巩膜炎、颅内压增高、葡萄膜炎、脉络膜新生血管、远视及Graves眼病等,也可为特发性。脉络膜皱褶患者可以无任何自觉症状,但检眼镜下很容易观察,眼底血管造影和光相干断层扫描检查有明显特征。临床医生提高对脉络膜皱褶的认识,有助于发现那些易继发脉络膜皱褶的疾病。

  • Spectral-domain optical coherence tomography characteristics of acute central serous chorioretinopathy

    Objective To observe the characteristics of spectral-domain optical coherence tomography (SD-OCT) for leakage point in acute central serous chorioretinopathy (CSC). Methods A total of 21 acute CSC patients (21 eyes) were enrolled in this retrospective study, including 17 men (17 eyes) and 4 women (5 eyes). The mean age was (47.3±8.8) years (range 35 - 66 years). The mean duration was (1.6±0.8) months (range 0.5 - 3.0 months). All patients were underwent mydriatic fundus photography, SD-OCT examination and fluorescein fundus angiography (FFA). SD-OCT and FFA images were carefully compared to observe the SD-OCT examination characteristics of fluorescence leakage point. Results 21/21 eyes had one fluorescein leakage point. In addition to serous retinal detachment, leakage point in the SD-OCT examination showed retinal pigment epithelium (RPE) protrusion in 10 eyes (47.6%), RPE detachment in 7 eyes (33.3%), highly reflective areas suggesting fibrinous exudate in the subretinal space in 3 eyes (14.3%), and RPE defect in 1 eye (4.8%). Conclusion The SD-OCT characteristics of acute CSC include RPE protrusion, RPE detachment, highly reflective areas suggesting fibrinous exudate in the subretinal space and RPE defect.

  • Fundus Analysis of Familial Exudative Vitreoretinopathy

    ObjectiveTo observe and explore the fundus characteristics and fundus fluorescein angiography of familial exudative vitreoretinopathy (FEVR) in different stages. MethodsA total of 15 patients (23 eyes) diagnosed as FEVR in the West China Hospital of Sichuan University from January 2007 to November 2013 were included. Clinical data and reports of fundus exams and fundus fluorescein angiography (FFA) were retrospectively analyzed. ResultsOne eye (4.35%) was classified as stage Ⅰ, 10 eyes (43.48%) were classified as stage Ⅱ, 8 eyes (34.78%) were classified as stage Ⅲ, and 1 eye (4.35%) and 3 eyes (13.04%) were classified as stage Ⅳ and V, respectively. The outcomes of fundus exams showed that the number of peripheral retinal blood vessels increased, and vessels straightened as well as narrowed, especially in the temporal area. FFA showed blood vessels suddenly shut in the equatorial retina and peripheral non-perfusion areas were observed. ConclusionTypical fundus characteristics and fundus fluorescein angiography changes of FEVR can be observed in different stages. Comprehensive fundus exams and family history are helpful to confirm relevant diagnosis.

  • Manifestation of fundus angiograph of polypoidal choroidal vasculopathy

    Objective To observe the manifestation of fundus angiographs of polypoidal choroidal vasculopathy (PCV). Methods Twelve PCV patients involved 7 males and 5 females aging from 40 to 69 year old (average 56.4). Fundus examination, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) were performed on 12 patients (12 eyes) with PCV, out of whom 5 underwent optical coherenece tomography (OCT). Results In 12 eyes, deep and (or) superficial hemorrhage and yellow hard exudations were found, including orange-red lesions in 6 and pre-retinal hemorrhage in 2. The results of FFA discovered orange-red spotty fluorescence in 6 eyes and choroidal vascular network in 4 eyes. At the late phase, leakage of polypoidal hyperfluorescence spot in all of the eyes except 2 without leakage were found. The images of ICGA showed typical dotted or clustered polypoidal hyperfluorescence in 12 eyes at the late phase. OCT disclosed protrusion of the retinal pigment epitelium (RPE) with a bumpy surface at polypoidal structure in 4 eyes and no change in 1 eye. Conclusions PCV mainly affects the elderly persons and mostly on unilateral eyes. Macular hemorrhage,serous RPED, and (or) neuroepithelial detachment with yellow hard exudations are the main manifestations. Branching choroidal vascular net with ployplike terminal anourysmal dilations can be discovered in FFA and ICGA. (Chin J Ocul Fundus Dis,2004,20:310-312)
