Corticosteroids are widely used to treat ocular fundus diseases such as inflammatory disease, macular edema and choroidal neovascularization. To increase local drug concentration and reduce systemic side effects, corticosteroids are often delivered by periocular or intravitreal injection. However there are still more and more clinical complications with the expanded scope of application of these drugs. In order to achieve the best riskbenefit ratio, fully understanding the pharmacological characteristics, indications, contraindications and complications of corticosteroid is critical for clinicians to prescribe this drug to their patients.
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.
Objective To evaluate the effects of retinal cryotherapy and intravitreal triamcinolone injection to treat Coatsprime; disease with exudative retinal detachment.Methods This was a prospective consecutive case study, and 21 patients (21 eyes) with Coatsprime; disease accompanied by exudative retinal detachment were enrolled. There were 19 males and two females patients, aged from two to 18 years. Fifteen eyes had partial retinal detachment (stage 3A) and six eyes had total retinal detachment (stage 3B). All patients underwent cryocoagulation and intravitreal triamcinolone injection. Three eyes underwent sclerotomy to drain subretinal fluid. Four eyes underwent further treatment by photocoagulation or cryotherapy for the residual abnormal blood vessels after the surgery. The follow-up ranged from three to 15 months with an average of seven months. Visual acuity, intraocular pressure, eye position and eye movements, slit lamp microscope, indirect ophthalmoscope and color fundus imaging were followed up. The last followup time was considered as the judgment time for the therapeutic effects. Results Six eyes had increased intraocular pressure after the surgery, which was controlled by local drug treatment. At the end of follow-up, 19 eyes had reattached retina, one eye had partial retinal detachment and one eye had total retinal detachment. The vision improved in three eyes,unchanged in 14 eyes, and decreased in two eyes. Other complications included strabismus (one eye) and cataract (four eyes). Conclusion The combined treatment of cryotherapy and intravitreal triamcinolone injection is an effective therapy for the Coatsprime; disease with exudative retinal detachment, as retina reattaches and visual function is saved in most patients after this treatment.
ObjectiveTo investigate the clinical, ophthalmological and pathological features of primary uveal lymphoma.MethodsRetrospective clinical study. From 2012 to 2018 in Beijing Tongren Eye Cener, 4 cases and 4 eyes of patients with primary uveal lymphoma were included in the study. Among them, 3 cases were male and 1 case was female. The average age was (54 ± 13.58) years old. The average time from initial diagnosis to pathological diagnosis was (18.50 ± 9.29) months. 3 cases were enucleated and 1 case was biopsied. Extranodal marginal zone lymphoma (EMZL) of the mucosa associated lymphoid tissue (MALT) was confirmed by pathological examination. BCVA, fundus color photography, color Doppler ultrasound and orbital MRI were performed in all eyes. UBM, OCT, FFA and ICGA were performed in 2 eyes, 3 eyes, 3 eyes and 2 eyes respectively. The clinical, imaging and pathological changes were observed. Following up time was ≥ 6 months.ResultsAt the initial diagnosis, BCVA was 0.6, 0.02 and 0.01 in 1, 2 and 1 eye respectively. Choroid, ciliary body and iris were involved in 3 eyes, choroid in 1 eye. The fundus of the eyes showed infiltration of choroid in yellow and white color, and the lesions were beyond the vascular arch to the equator and peripheral areas. Color Doppler ultrasonography showed that choroidal diffuse thickening and extrascleral extension (ESE) which was the corresponding hypoechoic areas behind the sclera. Among them, ESE showed crescent thickening in 1 eye and nodular thickening in 3 eyes. UBM showed that the echo of ciliary body was thicken and the internal echo was decreased with the iris involved. OCT showed that RPE was wavy and local retinal neuroepithelial layer detached. FFA showed that the early lesions were mottled with strong and weak fluorescence, and the late fluorescence leakage. The posterior wall of the eyeball was thickened and enhanced in MRI.ConclusionThe clinical manifestations of uveal lymphoma are various, color Doppler ultrasound has characteristic manifestations and ESE of crescent or nodular thickening is valuable in diagnosis.
