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.
Objective To investigate the clinical characteristics of patients with polypoidal choroidal vasculopathy (PCV) from Central China . Methods This was a retrospective study, and 403 eyes of 362 patients diagnosed as PCV by ocular fundus photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT) were enrolled. The general clinical data, fundus manifestation and ocular fundus examinations were statistically analyzed. Results Three hundred and sixty-two cases included 249 males (68.8%) and 113 females (31.2%). Age ranged from 45 to 91 years old, and mean age was (64.81plusmn;9.31) years old. Bilateral lesions were observed in 41 patients (11.3%) and unilateral lesions were observed in 321 patients (88.7%)． In these 403 eyes, typical orangered lesions were observed in 162 eyes (40.2%); yellowishwhite exudate could be found in 185 eyes (45.9%); 268 eyes (66.5%) showed variable degrees of subretinal hemorrhage. Drusen was found in 23 eyes (5.7%), pigment proliferation in 20 eyes (5.0%) and fiber vascular scar in 96 eyes (23.8%). The lesions of 386 eyes (95.8%) located in macular region, 53 eyes (13.2%) in peripapillary area. Lesions presented multifoci in 67 eyes (16.6%). Three hundred and four eyes (75.4%) presented typical polypoidal lesions and 152 eyes (37.7%) with abnormal branching choroidal networks. Hemorrhagic retinal pigment epithelial detachments (PED) were found in 200 eyes (49.6%) and serous PED in 96 eyes (23.8%), both existed in 25 eyes（6.2%）. OCT showed 56 eyes (13.9%) presented cystoid dark chamber between the neurosensory retina and 109 eyes (27.0%) with double-layer sign formed by the separation of retinal pigment epithelium and Bruchprime;s membrane (27.0%). Two hundred and seventy-four eyes (68.0%) were found with conelike elevation beneath the RPE layer and 151 eyes (37.6%) with neurosensory detachment. Conclusions In Central China, the majority of PCV patients were male, unilateral. Most PCV lesions were located in the macula. Subretinal hemorrhage, polypoidal lesions and abnormal choroidal vascular networks were common in the PCV patients. Hemorrhagic PED presented a higher ratio than serous PED.
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.
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.
Objective To observe the of macular serous neuroepithelial detachment and the necessary auxiliary examination methods for the diagnosis.Methods The clinical data of 46 patients (49 eyes) aged above 45 years with macular serous neuroepithelial detachment who have been diagnosed by binocular indirect ophthalmoscope and optical coherence tomography (OCT) were retrospectively analyzed. All the patients had undergone fundus fluorescein angiography (FFA) and indocyanine angiography (ICGA), and the diagnosis was established based on the results of FFA, ICGA and OCT. Results In these 46 patients (49 eyes), central serous chorioretinopathy (CSC) was found in 31 (34 eyes, 69.4%), agerelated macular degeneration (AMD) was found in 12 (12 eyes, 24.5%), and polypoidal choroidal vasculopathy (PCV) was found in 3 (3 eyes, 6.9%). In the 34 eyes with CSC, 12 eyes (35.3%) had typical CSC and 22 eyes (64.7%) had chronic CSC. If the 12 eyes with AMD, 9 eyes (75%) had occult CNV, 2 eyes (16.7%) had minimally classic CNV, and 1 eye had classic CNV. Conclusions The causes of serous macular neuroepithelial detachment in patients aged above 45 years are complex; ICGA may help to establish the definitive diagnosis of chronic CSC, occult CNV,and PCV should be considered.
Objective To investigate the imaging characteristics of patients with choroidal folds, which including ocular fundus, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optical coherence tomography (OCT). Methods The clinical data of 62 eyes of 34 patients with choroidal folds were analyzed retrospectively. The patients include 10 patients(20 eyes) of VogtKoyanagiHarada syndrome, 1 patients(2 eyes) of Behcet diseases, 11 patients(21 eyes) of other uveitis, 5 patients (9 eyes) of papolloedema, 2 patients(2 eyes) of choroidal tumor, 2 patients(4 eyes) of, hypotony with macular degeneration, 1 patient(2 eyes) of,Graves diseases, 1 patient (1 eye) of,blunt trauma and 1 patient(1 eye) of uveal effusion syndrome. All patients underwent the examination of direct ophthalmoscope, fundus color photography and FFA, meanwhile, 9 patients (17 eyes) with ICGA examination, 9 patients(18 eyes) with OCT examination. Results Choroidal folds were bright and dark stripes on the fundus, their numbers were variable. They can be arranged radially, horizontally, oblique or concentrically around the macular area, or radiating from optic disk but rarely over equator region. On FFA there were more folds which were subjected to coarse folds and wrinkles. They were obvious at early stage and no leakage at late stage. On ICGA choroidal folds showed normal or hypofluorescence at early stage, and hyperfluorescence or hypofluorescence at late stage. The hyperfluorescence or hypofluorescence bands were corresponding to the hypofluorescence of FFA but not obvious as FFA. On OCT choroidal folds involved choriod and retinal pigment epithelial layer (RPEL). Conclusion Choroidal fold is a bright and dark stripes that involved choriod and RPEL. The angiography showed hypofluorescence bands without leakage. Be familiar with the imaging features of choroidal folds can help to found the choroidal folds and the original diseases.
