ObjectiveTo observe the multimodal imaging features of the eyes with acute syphilitic post-polar squamous chorioretinitis (ASPPC) at different stages of disease.MethodsA retrospective case study. From July 2016 to March 2019, 8 patients (11 eyes) of ASPPC patients diagnosed in the ophthalmological examination of Yunnan Second People's Hospital were included in the study. Among them, there were 7 males (10 eyes) and 1 female (1 eye); the average age was 48.7±8.9 years; the average course of disease was 13.24 ±11.30 months. All patients underwent fundus color photography, infrared photography (IR), FAF, FFA, OCT, OCT angiography (OCTA). According to the stage and characteristics of the disease, the affected eyes were divided into acute phase and absorption phase, with 7 and 4 eyes respectively. We observed the color fundus images of ASPPC, IR, FAF, FFA, OCT, OCTA image characteristics of different disease stages.ResultsIn the acute phase, the posterior pole subretinal yellow-white squamous lesions, neuroepithelial detachment, and yellow-white exudates were observed in fundus color photography; uneven infrared reflections can be seen in the lesion area by IR; the posterior pole was round or scaly with strong autofluorescence in FAF, the range was larger than the fundus color photography; FFA arteriovenous stage lesions showed fuzzy weak fluorescence, the fluorescence gradually increased with time, the late stage showed a round-shaped strong fluorescence, surrounded by a weak fluorescence ring, and the area with thick exudation was covered by fluorescence; the neuroepithelium of the diseased area was detached, the uniform strong reflection signal can be seen in it by OCT. In the absorption phase, fundus color photography showed the yellow-white scaly lesions under the posterior retina absorption, and the pigment was slightly depleted; IR showed the mottled infrared reflection in the lesion area was significantly reduced compared with the acute phase; FAF showed the posterior spot-like strong autofluorescence, including "leopard spot-like changes" 3 eyes; FFA showed mottled fluorescent staining in the lesion, and no fluorescein leakage or accumulation; OCT showed needle-like protrusions in the RPE layer, and the outer membrane and ellipsoid zone were unclear; OCTA showed weakened choroidal capillary blood flow signal, the signal was missing in some areas.ConclusionsIn the acute phase of ASPPC, the posterior pole subretinal shows yellow-white squamous lesions, neuroepithelial detachment, yellow-white exudate, FFA shows late fluorescein leakage in the lesion area; in the absorption period, the fundus shows yellow-white lesions have been absorbed, and FFA shows fluorescence dyed without any leakage. OCT indicates that the RPE, outer membrane and ellipsoid zone are damaged to varying degrees. OCTA indicates that the choroid of the diseased area had weakened blood flow signal.
ObjectiveTo observe the clinical characteristics of patients with visual impairment caused by fungal sphenoid sinusitis and analyze the influencing factors related to visual prognosis. Methods A retrospective clinical study. From January 2006 to December 2020, 44 patients (55 eyes) with visual impairment caused by fungal sphenoid sinusitis confirmed by imaging and pathological examination in the Department of Ophthalmology of Beijing Tongren Hospital were included in the study. Patients was first diagnosed in the Department of Ophthalmology due to monocular or binocular vision loss, or binocular diplopia, limited eye movement and ptosis. All patients underwent visual acuity examination and fundus color photography. CT examination of paranasal sinus or orbit was performed in 37 cases; magnetic resonance imaging (MRI) of paranasal sinus, brain or orbit was performed in 34 cases. All patients underwent endoscopic sinus opening combined with intrasinus lesion clearance; 14 cases were treated with antifungal drugs after operation. The average follow-up time was 59.61±37.70 months. Comparison of clinical characteristics between invasive and non-invasive fungal sphenoid sinusitis were by χ2 test or Fisher exact test. The influencing factors with P＜0.2 in univariate analysis were selected for multivariate regression analysis. ResultsAmong the 44 patients, there were 19 males and 25 females; the ratio of male to female was 1:1.3; the average age of visual symptoms was 61.48 ± 12.17 years; 23 cases (52.3%, 23/44) suffered from immune dysfunction, including 21 cases of diabetes mellitus. The visual acuity decreased in 33 cases (44 eyes) (75.0%, 33/44). There were 15 cases of binocular diplopia with eye movement disorder (34.0%, 15/44), including 6 cases with visual impairment. The visual acuity of the affected eye was no light perception-0.8. There were 35 cases with headache (79.5%, 35/44). Nasal symptoms were found in 14 cases (31.8%, 14/44). There were 40 and 4 cases of Aspergillus and Mucor infection in sphenoid sinus, respectively. Among the 37 cases who underwent CT examination of paranasal sinus or orbit, there were soft tissue filling in the sinus cavity, including 19 cases of high-density calcification in the sinus cavity (51.4%, 19/37); bone defect of sinus wall were in 24 cases (64.9%, 24/37). There were 26 cases (70.3%, 26/37) of sinus wall osteosclerosis. MRI of paranasal sinus, brain or orbit was performed in 34 cases. T1WI of sphenoid sinus lesions showed low signal, high signal and equal signal in 14, 10 and 9 cases, respectively; T2WI showed high signal, low signal and equal signal in 13, 16 and 2 cases respectively. After enhancement, the lesions were strengthened in 11 cases, no obvious enhancement in 23 cases, and the surrounding mucosa was thickened and strengthened. The lesions involved the orbital apex and cavernous sinus in 18 and 16 cases, respectively; orbital apex and cavernous sinus were involved in 12 cases. Six months after operation, visual acuity was significantly improved in 27 eyes (65.9%, 27/41); visual acuity did not improve in 14 eyes (34.1%, 14/41). Multivariate regression analysis showed that the change of sinus wall osteosclerosis was associated with higher visual acuity improvement rate (odds ratio= 0.089, 95% confidence interval 0.015-0.529, P=0.008). ConclusionsFungal sphenoid sinusitis related visual impairment is relatively common in elderly female patients with low immune function; monocular vision loss with persistent headache is the most common clinical symptom; imaging findings of sphenoid sinus lesions are an important basis for diagnosis. Sphenoid sinus opening combined with sinus lesion clearance is an effective treatment. After operation, the visual acuity of most patients can be improved. The prognosis of visual acuity was relatively good in patients with hyperplasia and sclerosis of sphenoid sinus wall bone.
In recent years，there are more and more cases of retinal infectious diseases in China，however，the diagnosis and management of those patients are still big challenges for our ophthalmic clinicians. It is our top priority to improve their capacity of early diagnosis for those diseases. We need to know the relationship between retinal infectious diseases and systemic infections, their predisposing factors. We also need to be familiar with the typical as well as atypical clinical features of those diseases. Vitreoretinal surgery already becomes a powerful tool to make diagnosis of retinal infectious diseases now；we need to make full use of this tool combined with modern technologies of microbiology, cytology, immunology and molecular biology to provide objective scientific evidences for the early diagnosis of retinal infectious diseases.
Objective To observe the clinical manifestations, therapeutic efficacy and results of bacterial culture of seven patients of scleral buckle (SB) infection after scleral bulking surgery. Methods Seven patients (seven eyes) underwent SB removal for SB infections were enrolled in this study. The patients included four males (four eyes) and three females (three eyes). The patients aged from 12 to 69 years, with a mean age of 42.7 years. There were four right eyes and three left eyes. The duration (interval between primary surgery and SB removal) ranged from two weeks to ten years, with a mean of 47.5 months. Six patients were concurrent with systemic disease. All the patients were examined for visual acuity, slit lamp microscope and indirect ophthalmoscope examination. Some patients also received external eye examination and fundus photography. Whether SB exposure or not and the clinical manifestations were observed. SB removal was performed in all the patients and the SB were sent to the laboratory for bacterial culture. The follow-up time ranged from two weeks to eight months, with a mean of 3.2 months. Whether infections recurrence and retinal detachment or not were observed. Results SB exposure was in three eyes. Obvious ocular pain and swelling, conjunctival hyperemia and visible yellow-white discharge in the conjunctival sac were presented in two eyes; irritation and discharge were in one eye. No SB exposure was in four eyes. Ocular pain and swelling, conjunctival hyperemia and visible yellow-white discharge in the conjunctival sac were presented in two eyes. Repeated subconjunctival hemorrhage and diplopia were presented in one eye. Visual acuity decline, conjunctival sac discharge and total retinal detachment were in one eye. All patients had no intraocular inflammation. The infection was controlled after SB removal and the retina was attached during the follow-up. The bacterial culture were all positive, which included Staphylococcus aureus, Staphylcoccus epidermidis and Erysipelothrix rhusiopathiae, Gram positive corynebacterium, Aspergillus flavus, Kocuria roseus, Streptococcus oralis, Maxwell Corynebacterium. Conclusions The clinical manifestations of SB infection and the pathogenic microorganisms are variable. SB removal can control the infection.
