  • Comparative observation of fundus ophthalmoscopic image characteristics of central serous chorioretinopathy

    Objective To observe ophthalmoscopic image characteristics of central serous chorioretinopathy (CSC). Methods Twenty-one eyes of the 18 patients diagnosed with CSC were enrolled in this study.The patients included 12 males (14 eyes) and six females (seven eyes).The patients ages ranged from 26 to 47 years,with a mean age of (39.1plusmn;5.4) years. There were nine patients (11 eyes) with acute CSC, seven patients (seven eyes) with chronic CSC, and two patients (three eyes) with recurrent CSC. All the patients were examined using color fundus photography including infrared (IR), auto-fluorescence (AF), near infrared ray-auto-fluorescence (NIR-AF), fluorescein angiography (FA) and indocyanine green angiography (ICGA) photography. The ophthalmoscopic image characteristics of CSC were comparared. Results The circular serous retinal detachments of 21 eyes were depicted in color images of the ocular fundus, which in the IR showed the hypo-fluorescence. Ten eyes displayed mottled hyper-fluorescent spots associated with serous retinal detachments corresponding to the leakage points. The serous retinal detachments of 15 eyes in the AF images showed hypo-fluorescence, six eyes showed hyper-fluorescence. Fourteen eyes presented with hypo-or hyper-fluorescent spots corresponding to the leakage points, seven eyes presented without abnormal fluorescence corresponding to the leakage points. In addition, three eyes with acute CSC showed many scattered hyper-fluorescent spots, which showed hypo-fluorescence in the ICGA. The serous retinal detachment of 15 eyes exhibited hypo-fluorescence in the NIR-AF images, six eyes showed hyper-fluorescence. Fourteen eyes presented with hypo- or hyper-fluorescent spots corresponding to the leakage points, seven eyes presented without abnormal fluorescence corresponding to the leakage points. Twenty-one eyes in FA identified the leakage. Eight eyes showed regional choroidal delayed filling, 13 eyes exhibited regional choriocapillary dilatation during 1-5 minutes after injection of ICGA. During 1-5 minutes after injection of ICGA, six eyes showed more lesions than FA, three eyes showed obvious patchy hypo-fluorescence whereas the FA were normal. Conclusions CSC has its own characteristic fundus images in the IR, FA and NIR-A. FA is still the photographic method of choice, but ICGA can reveal lesions of the choroid in CSC. IR, FA and NIR-AF are not as good as FA and ICGA for detecting of leakage points.

  • How to use optical coherence tomography to improve diagnosis and treatment of ocular fundus disease?

    The improvement of diagnostic levels for fundus diseases depend on the advancements of fundus imaging technology. Different fundus imaging technologies allow doctors to inspect ocular fundus from different aspects such as morphological or functional changes of retina. As a basic fundus examination method, optical coherence tomography provides highresolution and crosssectional retinal images coupled with noninvasive advantages. Fully understanding of the advantages and disadvantages of each fundus imaging technique, appropriate choosing one or combining several imaging techniques, and optimizing diagnostic procedures for each fundus disease are crucial steps to improve our diagnostic levels of ocular fundus diseases. 

    Objective To observe the characteristics of spectraldomain optical coherence tomography (SD-OCT) and fundus autofluorescence (FAF) in acute and chronic central serous chorioretinopathy (CSC).Methods Seven-three eyes of 67 patients with CSC diagnosed by slit-lamp microscopy, fundus photochromy, fundus fluorescein angiography (FFA) and indocyanine green angiography were enrolled in this study. All the patients were examined for FAF and SD-OCT. The patients were divided into acute CSC group (37 patients, 37 eyes) and chronic CSC group (30 patients,36 eyes) according to the clinical features and FFA images. According to the OCT feature in retinal detachment area, they were divided into three categories, which including intact, non-intact and atrophy outer segment, respectively. According to the FAF characteristics, they were divided into hyper-FAF, hypo-FAF and mixed type, respectively. The characteristics of SD-OCT and FAF of both acute and chronic CSC patients were evaluated and analyzed. Results In acute CSC group, 19 eyes (51.35%) were hypo-FAF, 18 eyes (48.65%) were hyper-FAF. In chronic CSC group, two eyes (5.56%) were hypo-FAF, 16 eyes (44.44%) were hyper-FAF, and 18 eyes (50.00%) were mixed type. There was significant difference between both groups (chi;2=31.872,P=0.000). The SD-OCT results showed that in acute group, 15 eyes (40.54%) were intact outer segment, 18 eyes (48.65%) were non-intact outer segment, and four eyes (10.81%) were atrophy outer segment. In chronic group, five eyes (13.89%) were intact outer segment, 17 eyes (47.22%) were non-intact outer segment, and 14 eyes (38.89%) were atrophy outer segment.

  • Characteristics of indocyanine green angiography in inactive polypoidal lesions of polypoidal choroidal vasculopathy

    Objective To observe the characteristics of indocyanine green angiography (ICGA) in inactive polypoidal lesions of polypoidal choroidal vasculopathy (PCV). Methods The clinical data of 36 PCV patients (37 eyes) with inactive polypoidal lesions were retrospectively analyzed. The follow-up of 11 eyes were ranged from nine to 29 months, with a mean of (12.3plusmn;5.5) months. All the patients were examined for visual acuity, intraocular pressure, slit lamp microscope, fundus photography, fundus fluorescein angiography (FFA) and ICGA. According to the ICGA characteristics, PCV lesions were divided into active polypoidal lesions (pocket like hyperfluorescence at early stage and fluorescence leakage or stained with fluorescein at late stage) and inactive polypoidal lesions (pocket like hyperfluorescence and it was gradually faded). According to clinical and ICGA characteristics, inactive polypoidal lesions were divided into asymptomatic group, atrophic and/or cicatricial group and combined (with active polypoidal lesions) group. The visual acuity, fundus, lesions change and image characteristics of three groups were evaluated and analyzed. Results Among the 37 eyes, the time from indocyanine green (ICG) injection to inactive polypoidal lesions begin showing was ranged from 8.2 to 27.0 minutes, with a mean of (15.5plusmn;4.8) minutes. There were five eyes (13.5%), eight eyes (21.6%) and 24 eyes (64.9%) in asymptomatic group, atrophic and/or cicatricial group and combined group, respectively. The results of fundus examination showed that there was no hemorrhage, exudates, retinal pigment epithelium detachment (PED) and/or neural retina detachment in asymptomatic group; atrophy lesions and/or scar lesions were observed in atrophic and/or cicatricial group and there was also no hemorrhage, exudate, PED and/or neural retina detachment; there was no atrophy lesion and/or scar lesion, but there were 10 eyes with subretinal hemorrhage, 15 eyes with retinal exudate, 10 eyes with PED and four eyes with neural retina detachment in combine group. The results of ICGA showed that there were inactive polypoidal lesions in asymptomatic group; inactive polypoidal lesions located at the border of atrophy lesions and/or scar lesions in atrophic and/or cicatricial group; active polypoidal lesions and inactive polypoidal lesions coexisted in combine group. In 11 eyes which completed the follow-up, inactive polypoidal lesions regressed in three eyes (27.3%), partial regressed in two eyes (18.2%), unchanged in six eyes (54.5%). Conclusions The inactive polypoidal lesions of PCV mainly appear in the middle or late stage of ICGA and are manifested in asymptomatic, atrophic and/or cicatricial and combined eyes. The combined type which coexisted with active polypoidal lesions is the main form. 

  • The relationship between the changes of visual acuity and classification of polypoidal choroidal vasculopathy

    Objective To observe the prognosis of visual acuity (VA) of patients with different classification of polypoidal choroidal vasculopathy (PCV). Methods Sixty-seven PCV patients (68 eyes) diagnosed by fundus photography, fundus fluorescein angiography, indocyanine green angiography (ICGA) and ocular coherence tomography were enrolled in this retrospective study. The patients were classified into static, exudative, small hemorrhage and large hemorrhage according to activity and pathological characteristics of lesions. The patients were classified into aciniform, single or several single, combined branching choroidal vascular network (BVN) according to morphological characteristics and combination with BVN of lesions on ICGA. The patients also were classified into macular, vascular arcade, peripapillary and mixing zone according to distribution of lesions. The VA of all the types were observed. Results There were 16, 19, 19, 14 eyes in the type of static, exudative, small hemorrhage and large hemorrhage PCV, which with logMAR VA of 0.34plusmn;0.52, 0.70plusmn;0.98, 0.60plusmn;0.50, 0.91plusmn;0.75 respectively. The VA of static PCV patients was better than that in exudative, small hemorrhage and large hemorrhage PCV patients (q=4.75, 4.26, 5.13; P<0.05). There was no significant difference of VA between exudative and small hemorrhage PCV patients (q=0.98, P>0.05). There were 22, 38 and eight eyes in the type of aciniform, single or several single, combined BVN PCV, which with logMAR VA of 0.52plusmn;0.55, 0.59plusmn;0.43, 0.80plusmn;0.95 respectively. The VA of combined BVN PCV patients was worse than that in aciniform and single or several single PCV patients (q=3.81, 3.02;P<0.05). There were 34, 13, 8 and 13 eyes in the type of macular, vascular arcade, peripapillary and mixing zone PCV, which with logMAR VA of 0.78plusmn;0.43, 0.57plusmn;0.37, 0.38plusmn;0.27, 0.74plusmn;0.41 respectively. The VA of macular PCV patients was less than that in vascular arcade and peripapillary PCV patients (q=4.61,5.11;P<0.05). There was no significant difference of VA between macula and mixing zone PCV patients (q=0.73,P>0.05). Conclusions The VA of PCV patients is variable.It is related to activity and pathological characteristics of lesions, morphological characteristics and combination with BVN of lesions on ICGA, and distribution of lesions. 

  • The differences and similarities between polypoidal choroidal vasculopathy and age related macular degeneration is worthy for further investigation

    Polypoidal choroidal vasculopathy (PCV) is one of the exudative maculopathy, which is characterized by retinal pigment epithelium detachment, subretinal hemorrhages and sensory retinal detachment. The prevalence of polypoidal choroidal vasculopathy (PCV) reached 33.5% in neovascular age related macular degeneration (AMD) for Chinese population. Indocyanine green angiography showed a single or multiple focal nodular areas of hyperfluorescence arising from the choroidal circulation and currently is recognized a gold standard for diagnosis of PCV. The histopathologic findings indicated that hyalinization of choroidal vessels, like arteriosclerosis. Up to now there is no reliable evidence to demonstrate the difference in genetic study. The study of environment factor showed hypertension is associated with PCV closely than with AMD. PCV and AMD is different genotype or different phenotype as well as difference in pathogenesis need further studies.

  • Clinical features of polypoidal choroidal vasculopathy with retinal pigment epithelium tears

    Objective To observe the clinical features of polypoidal choroidal vasculopathy (PCV) with retinal pigment epithelium (RPE) tears. Methods Twelve patients of PCV with RPE tears (12 eyes) were enrolled in this study. The patients included eight males and four females, with a mean age of 58.6 years (from 39 to 71 years old). All the patients were affected unilaterally, including eight right eyes and four left eyes. There were one eye with serous RPE detachment and 11 eyes with hemorhagic RPE detachment. All the patients were examined for fundus photography, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA), three patients were examined for optical coherence tomography (OCT). The location of RPE tear was classified as within vascular arcade, on vascular arcade, and outside vascular arcade. The shape of tear was classified as crescent, semilunar, or irregular. The features of fundus, FFA, ICGA and OCT were observed. Results Fundus examination presents a gray lesion in all eyes. The location of tear were within vascular arcade in four eyes (33.3%), on vascular arcade in five eyes (41.7%) and outside vascular arcade in three eyes (25.0%). The shape of tears were crescent (one eye, 8.3%), semilunar (ten eyes, 83.3%) or irregular (one eye, 8.3%). The RPE tear region present transimitted fluorescence of at the early stage of FFA and hyperfluorescence with a clear border at late stage. There was no leakage, and at the border of hyperfluorescence, blockage fluorescence of rolled and contracted RPE was present. In ICGA manifestation, transimitted fluorescence was found in RPE tear region at early stage, and a clear border was seen in nine eyes at late stage. There was also blockage fluorescence in ICGA of contracted RPE. In OCT manifestation, the RPE reflections were disappeared, and at the margin of tear, the contracted RPE present a dense rolled b reflection. Conclusions In PCV patients, RPE tears are semilunar and usually located within or around the vascular arcade. Fundus angiography shows transimitted fluorescence at the RPE tear region, and curl blockage fluorescence at the edges. OCT shows RPE reflection is disappeared in the tear region and a b reflection at the edges.
