The clinical manifestations of infectious retinal diseases are complicated, especially these result from serious infectious diseases such as acquired immune deficiency syndrome (AIDS), tuberculosis and syphilis infections. It is an important issue to differentiate infectious retinal disease from noninfectious intraocular inflammation in the clinic. It is, therefore, highly desirable to follow a proper steps to reach the correct diagnosis. Complete history review and comprehensive ocular examination remains the first step in diagnosing infectious retinal diseases. Although an array of laboratory and serological tests are available to assist in the diagnosis, some situations may require a diagnostic therapy or a tissue biopsy. Identification of the pathogen and histopathologic examination of the ocular specimen remain to be the gold standard of diagnosis. Initiation a specific and appropriate antimicrobial therapy needs multidisciplinary collaborations including ophthalmologists and infectious specialists. Updated knowledge of general medicine and management of infectious diseases, interdisciplinary collaborations and optimization of treatment processes will improve the diagnosis and treatment of retinal infectious diseases in the future.
PURPOSE: To investigate the treatment of severe bacterial endophthalmitis. METHODS:The curative effects of vitrectomy after intravitreal antibiotics and steroids (IVAS)for the treatment of 23 patients with bacterial endophthalmitis (group I)and vitrectomy and IVA at the same time for the treatment of 28 patients with bacterial endopbthalmitis (group I)were analyzed retrospectively. RESULTS: The rate of curative effects of two groups were similar,while the marked curative effects in group I (47.8% )was significantly higher than that of the group I (17.9%). The average period of eliminating infiamation of group I was longer than that of group I , and the incidence of postoperative retinal detachment of group Ⅱ was 3 times more than that of group I . CONCLUSION :It was indicated that vitrectomy after IVAS may increase the security of vitrectomy and the curative effects of severe bacterial ndophthalmitis.
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.
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.
