ObjectiveTo observe the ocular manifestations of presumed ocular tuberculosis in patients with pulmonary tuberculosis. MethodsOne hundred and fifty nine patients with pulmonary tuberculosis received examinations of visual acuity, slit lamp microscopy and indirect ophthalmoscopy. Those patients with retinochoroidal inflammatory lesions, retinal hemorrhages or detachments underwent fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) to determine whether the presumed ocular tuberculosis was involved. There were 9 patients (16 eyes, 5.67%) of presumed ocular tuberculosis, including 5 males and 4 females. The age was ranged from 19 to 64 years old, with an average of 35.12 years. Seven patients were affected bilaterally and 2 patients affected unilaterally. There were 8 patients (15 eyes, 93.75%) with uveitis and 1 patient (1 eye, 6.25%) with central retinal vein occlusion (CRVO). The blood laboratory tests were negative in all cases. ResultsThe corrected vision was from light sensation to 0.15 in 6 uveitis eyes, 0.8 to 1.0 in 10 eyes. The anterior segment change was found in 10 eyes, which including granulomatous uveitis (8 eyes) and non-granulomatous uveitis (2 eyes). Granulomatous uveitis eyes had iris nodules, posterior synechia of the iris and mutton-fat keratic precipitates (KP). Non-granulomatous uveitis eyes had KP only. Choroidal tubercles were found in 7 eyes in which 3-7 off-white lesions of varying sizes were found with local retinal detachment. FFA revealed hypo-fluorescence with obscure boundary in arterial phase and arterial and venous phase, and hyper-fluorescence with obscure boundary in later phase. OCT showed retinal pigment epithelium uplift. There was 1 eye with CRVO, which had punctate, splinter and linear hemorrhage, white lesions in some hemorrhagic focus. ConclusionThe presumed ocular tuberculosis eyes showed mainly granulomatous inflammation and multiple choroid tubercles, and CRVO sometime.
ObjectiveTo investigate the clinical characteristics, treatments and prognosis of ocular toxoplasmosis (OT).MethodsA retrospective clinical trial. Twelve cases (14 eyes) with OT which was confirmed by clinical and laboratory tests were included in the Department of Ophthalmology, Taihe Hospital in Shiyan and the Department of Ophthalmology, Beijing Chaoyang Hospital in Beijing from July 2011 to June 2019. Among the 12 cases, 6 cases were female (7 eyes) and 6 cases were male (7 eyes). The mean age of the participants was 33.4±12.8 years and the duration of illness ranged from 7 days to 30 years. Fungal endophthalmitis, viral uveitis and non-infectious uveitis were misdiagnosed in 2 cases respectively at the first visit. All the patients underwent BCVA, intraocular pressure, slit-lamp microscope, fundus color photography examinations and toxoplasma-specific serological antibodies tests. Intraocular influid were detected for 7 cases, among which 1 case for antibody only, and 6 cases for Goldmann-witmer coefficient (GWC). Of the 6 cases tested for GWC, 4 cases were tested with PCR assay in the ocular fluid addtionally. FFA was performed in 5 cases (6 eyes) and OCT in 6 cases (6 eyes). Eleven cases were treated with antitoxoplasma therapy. The follow-up duration after treatment varied from 1 week to 39 months. BCVA, clinical features and prognosis were retrospectively analyzed.ResultsSpecific antibody seropositivity of Toxoplasma gondii was detected in all 12 patients. Of the 7 cases tested with intraocular fluid, 1 case was IgG positive and the other 6 cases with 5 cases with GWC ＞4 and 1 case with 2＜ GWC ＜4. Only 1 case (25%) was positive among 4 cases with PCR assays meanwhile. BCVA was:＜0.1 in 4 eyes, 0.1～0.3 in 6 eyes and ＞0.3 in 4 eyes. KPs with or without anterior chamber flash or cells could be detected in 6 eyes,congenital macular defect 1 eye, vitreitis 3 eyes (2 eyes with multiple retinal pigmentation foci and 1 eye with tractive retinal detachment), and coexistence of new and old lesions with Kyrieleis arteritis 2 eyes. Nine eyes showed different degrees of vitreous inflammation (75% of 12 active eyes). Single lesion was present in 4 case (4 eyes) and multiple lesions were present in 8 cases (10 eyes). There were no statistically significant changes in BCVA of OT patients before and after treatment (P=0.83). Involvement or adjacent to macula of he primary lesions, misdiagnosis and mistreatment led to the poor prognosisi of visual acuity.ConclusionsThe fundus of OT can show single lesion or multiple lesions, and the active phase is often accompanied by vitreous inflammation. The primary lesion involves or is close to the macular area, misdiagnosis and mistreatment are the main reasons for the poor visual prognosis of patients.
ObjectiveTo observe the clinical characteristics of adult patients with ocular toxoplasmosis (OT).MethodsThis study was a retrospective clinical trial. Among the 83 consecutive OT patients diagnosed in the Zhongshan Eye Center of Sun Yat-Sen University, 14 patients (16.9%, adult group) aged ≥18 years were included in the study from January 2017 to December 2019. A total of 14 OT patients (children group) aged less than 18 years who had consecutive visits from July to December 2019 were selected as controls. All patients underwent BCVA, slit lamp microscope, fundus color photography, and B-mode ultrasound examination. Eighteen cases underwent UBM examination, including 6 and 12 cases in the adult group and child group respectively; 23 cases underwent FFA examination, including 12 and 11 cases in the adult group and child group respectively. Snellen visual acuity chart was used for BCVA examination, which was converted into logMAR visual acuity in statistics. We compared the two groups of patients' residence (urban or rural), history of contact with dogs and cats, main symptoms, reasons for treatment, course of disease, and clinical and imaging characteristics and so on. For measurement data conforming to normal distribution, t-test was performed for comparison between groups; for Skewness distribution measurement data, rank sum test was performed for comparison between groups.ResultsCompared with the adult group and the child group, there was no significant difference in the canine-cat contact history (Z=2.661, P=0.257) and the time from first diagnosis to diagnosis (t=−0.186, P=0.351); compared with the children group and the adult group, the patient's living environment was mainly urban, and the course of disease was significantly shorter (Z=−2.005), and the difference was statistically significant (P=0.047). The logMAR BCVA of the adult group and the child group were 0.81±1.08 and 2.08±1.30, respectively, and the difference was statistically significant (Z=−2.811, P=0.004); compared with the child group, the adult group had lighter vitreous opacities, but the difference was statistical significance (Z=7.847, P=0.048). FFA examination revealed 20 cases of "fern-like" leakage of retinal capillaries. Among them, the adult group and child group were 10 (83.3%, 10/12) and 10 (90.9%, 10/11) cases respectively.ConclusionsAdult patients account for 16.9% of OT patients. Compared with children, adult patients mostly live in towns or cities, have a short course of disease, good vision at first diagnosis, and mild inflammation or hyperplasia of the vitreous cavity. FFA is helpful for the diagnosis of adult OT.
