Objectives To observe the clinical features of a pedigree of dominant drusen with high supermetropia. Methods Three patients in a family with dominant drusen were retrospectively reviewed. The refractive conditions were confirmed by computer and manual refraction examination with pupils dilated by tropicamide. Color fundus photography and fluorecein angiography were carried out with a FF450 Plus Zeiss camera. The fundus fluorescein angiography (FFA) photos were analyzed. Standard electroretinogram responses (ERGs) were also recorded. The characteristics of refractive condition, color fundus photos, FFA and ERG of the patients were analyzed. Results Various degrees of drusen were observed in the retinae of the three patients. The disease in the younger brother of the proband was mild and in the mother is severe. A large number of drusen existed in the peripheral retina as well as macula in the mother of the proband. FFA revealed window defects corresponding to the drusen. The dilated refractive results showed high supermetropic refractive error in the three patients. All of the eyes except the left eye of the mother of the proband showed refractive amblyopia. The amplitude of the photopic ERGs were decreased but the scotopic ERGs were normal in the younger brother of the proband. The scotopic and photopic ERGs of the proband and her mother were normal. Conclusion Patients with dominant drusen in combinnation with high hypermetropic refractive error and amblyopia may occur.
Objective To characterize the clinical features of punctate inner choroidopathy (PIC) in Chinese patients.Methods The clinical data of 75 PIC patients (112 eyes) attending this center from June 1999 to October 2009 were reviewed retrospectively. All patients received routine examination and fluorescein fundus angiography (FFA). Twentyeight patients also received indocyanine green angiography (ICGA). VISUPAC 3.3 software was used to determine the size of lesions in early image of FFA at the artery stage. Results Of the 75 PIC patients (112 eyes), 54 patients (72%) were female, 37 patients (49%) were bilateral cases. Sixty patients (80%) were myopic, including eight patients (7%) with mild myopia, 22 patients (20%) with moderate myopia, and 57 patients (51%) with high myopia. The mean age at presentation was 32 years (range: 17-61). Multifocal PIC lesions (1-56 lesions) were mostly restricted to posterior pole of affected eyes (95%). Eightyfour eyes (75%) had 10 PIC lesions. The active lesions were yellowwhite and butterlike, 20-500mu;m in diameter. FFA showed that most acute lesions were early hyperfluorescence, and stained or slightly leaked on late period. The atrophic lesions were pouchedout, 502000 mu;m in diameter, with irregular pigmentation. Choroidal neovascularization developed in 70 eyes (63%). Papilledema (three eyes, 3%), staining of optic disc on latephase fluorescein angiography (three eyes, 3%), and segmental retinal phlebitis (two eyes, 2%) were rare.Conclusions PIC primarily affects young women with moderate or high myopia. It is featured by multifocal small yellow creamy lesions and/or atrophic punchedout lesions principally in the posterior pole. Choroidal neovascularization is the most common complication.
Objective To observe the characteristics of fundus fluorescein angiography (FFA) in different types of pathologic myopic maculopathy and evaluate the influence factor.Methods The clinical data of 251 patients (451 eyes) with pathologic myopic maculopathy were retrospectively analyzed. The patients were divided into 6 groups according to FFA characteristics: (1) lacquer cracks (LC); (2) choroidal neovascularization (CNV); (3) macular hemorrhage with LCs; (4) Fuchs spots; (5) macular atrophy; (6) macular hole. Their relationship with age, gender, refraction and (BCVA) were analyzed.Results Older age was significantly associated with CNV and macular atrophy (OR=1.034,CI=1.019-1.049,P＜0.001;OR=1.054,CI=1.031-1.076,P＜0.001; respectively);younger age was associated with hemorrhage with LC (OR=0.906,CI=0.876-0.937,P＜0.001). Higher myopic refractive error was associated with macular atrophy (OR=0.762,CI=0.705-0.824,P＜0.001), whereas lower myopic refractive error was associated with CNV and macular hole(OR=1.233,CI=1.136-1.338,P＜0.001;OR=1.554,CI=1.185-2.038,P＜0.001; respectively). A worse visual acuity was associated with CNV (OR=1.835,CI=1.180 -2.854,P=0.007), while better visual acuity was associated with LC (OR=0.506,CI=0.328 - 0.782,P=0.002). There was no gender difference in distribution of high myopic maculopathy types. Conclusions Pathologic myopic maculopathy can be divided into six types. With increasing age, the incidence rates of CNV and macular atrophy increases, hemorrhage with LC but decreases. With the rise of myopic refractive, the incidence rates of CNV and macular hole decreases, macular atrophy but increases.
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.
ObjectiveTo explore the effects of corticosteroid on peripheral blood T lymphocyte subsets in patients with coronavirus disease 2019 (COVID-19).MethodsThis was a retrospective study and 376 patients were included in the study. The patients were classified into three type: moderate type (118 patients), severe type (215 patients), critical type (43 patients). Six critical patients died. T lymphocyte subsets were analyzed and compared among these patients. In severe patients, T lymphocyte subsets were compared between no corticosteroid therapy patients (178 patients) and patients who were treated with corticosteroid for 3 to 5 days (37 patients).Results(1) In contrast with those in moderate patients, in severe patients total lymphocytes [(1359.2±597.9)×106 vs. (1703.7±702.4)×106/L, LSD-t=4.786, P<0.001], total T lymphocytes [(949.2±454.0)×106 vs. (1235.5±555.7)×106/L, LSD-t=5.175, P<0.001] and CD8+ T cells [(336.8±189.8)×106 vs. (461.7±242.8)×106/L, LSD-t=5.332, P<0.001] decreased significantly, and CD4+/CD8+ ratio (1.81±0.92 vs. 1.64±0.74, LSD-t=1.574, P=0.116) was increased. In contrast with those in severe patients, in critical patients CD4+/CD8+ ratio (2.23±1.24 vs. 1.81±0.92, LSD-t=2.627, P=0.009) increased and CD8+ T cells [(232.5±159.8)×106/L vs. (336.8±189.8)×106/L, LSD-t=2.867, P=0.004] decreased significantly, total lymphocytes [(1161.1±583.7)×106/L vs. (1359.2±597.9)×106/L, LSD-t=1.772, P=0.077], total T lymphocytes [(790.5±419.3)×106/L vs. (949.2±454.0)×106/L, LSD-t=1.846, P=0.066] also decreased but without significant difference. There was no significant difference between dead and survived critical patients. (2) In severe type, in contrast with no corticosteroid therapy patients, 37 patients were therapy with corticosteroid for 3 to 5 days, and their total T lymphocytes [(770.6±480.3)×106 vs. (986.3±440.7)×106/L, t=2.666, P=0.008] and CD4+/CD8+ ratio (1.30±0.73 vs. 1.91±0.92, t=3.771, P<0.001) were decreased significantly.ConclusionsIn COVID-19 patients, lymphocytes, T lymphocytes and CD8+ T cells are decreased, but CD4+/CD8+ ratio is increased, and these changes are positively related to the severity of the disease. After corticosteroid therapy, the increase of CD4+/CD8+ ratio is relieved, but T lymphocytes are decreased further.
