ABSTRACT
O objetivo deste trabalho é relatar um caso de trauma ocular por projétil de arma de fogo, que atingiu e se alojou na cavidade orbitária, desenvolvendo coriorretinite esclopetária. Foram abordados o mecanismo fisiopatológico, os principais achados clínicos e de exames complementares, além das opções de tratamento. As características do caso relatado reforçam a importância de uma abordagem multidisciplinar no trauma ocular.
The objective of this study is to report a case of ocular trauma by gunshot bullet, which struck and lodged in the orbit, developing chorioretinitis sclopetaria. We also addressed the pathophysiological mechanism, the main clinical findings and laboratory tests, and treatment options. The characteristic of this case enhances the importance of a multidisciplinary approach in the ocular trauma.

Objective To evaluate the clinical features and treatment outcomes of ocular posteriorsegment syphilis.Methods The clinical data of 24 patients with active ocular syphilis wereretrospectively reviewed.The diagnosis was made first in eye clinic,and verified by treponema pallidumparticle agglutination(TPPA)and rapid plasma reagin(RPR).The patients,17 males and 7 females,aged from 30 to 63 years with an average of 47.6 years.The duration of symptoms ranged from 3 days to2 years with an average of 5.8 months(≤1 month,7 cases;1-3 month,5 cases;3-6 months,5 cases;>6 months,7 cases).There were 18 bilateral cases and 6 unilateral cases.The result of humanimmunodeficiency virus(HIV)test was negative for all cases.Twenty-three patients received systemicpenicillin therapy and 1 patient was treated with oral erythromycin due to penicillin allergy.Beforetreatment,the mean visual acuity was 0.17±0.1 9,the mean titer of RPR was 1:84.The follow-up periodwas half a year.Results The major ocular manifestations included bilateral(16 cases)or unilateral(1case)chorioretinitis,unilateral retinal vasculitis(2 cases),unilateral neuroretinitis(2 cases),andbilateral(2 cases)or unilateral(1 case)optic neuritis.The mean follow-up visual acuity was 0.60±0.29,the mean follow-up titer of RPR was 1:18.8.Some patients had got the diagnosis and prompt treatment atthe early stage of the disease and their visual acuity recoveried very well.Conclusions The majormanifestion of ocular posterior segment syphilis is chorioretinitis.It is important tO consider the possibilityof syphilis when patients have inflammation of posterior segment.Prompt serology examination andpenicillin treatment are the keys to cure ocular syphilis.
ABSTRACT
Objective To assess the effectiveness of transpupillary thermotherapy (TTT) for the treatment of central exudative chorioretinopathy. Methods Tweenty nine eyes with central exudative chorioretinopathy were treated with Iris 810 nm diode laser TTT. The laser beam size was 1.0, 2.0 or 3 0 mm with power settings between 80 300 mW and treatment time 60 sec. The follow up periods were wihzin 4 40 weeks. The therapeutic effect was accessed by visual acuity examination,dinect ophthalmoscopy and fluorescein or indocyanine green angiography. Results The visual acuity improved in 8 eyes (28%), remained no change in 19 eyes (65%) and decreased in 2 eyes (7%). Choroidal neovascularization were closed in 12 eyes in fundus angiography. The symptoms alleviated in 10 patients. Conclusion Transpupillary thermotherapy is a potential treatment for the central exudative chorioretinopathy.
ABSTRACT
Objective To evaluate the effects of traspupillary thermotherapy (TTT) for the treatment of central exudative chorioretinopathy (CEC). Methods Twelve eyes of 12 patients who suffered from CEC were treated by using a diode laser at 810 nm. A variable spot size of 0.5 mm 2 0 mm was used depending on the size of choroidal neovascularization (CNV).The treatment was initiated in one spot for 55 to 60 seconds duration at a power range between 200 350 mW, and the treated area revealed no visible color change to a light gray appearance. Preoperative and postoperative fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in 10 of the 12 eyes. Results The visual acuity in all eyes was improved to different degree over a period of 3 10 months. Five or more lines improvement measured by Snellen chart in visual acuity was found after the treatment in 4 eyes, three to five lines in 5 eyes and one to two lines in 3 eyes. All eyes demonstrated decreased or vanished exudation in FFA. CNV disappeared or decreaced in 8 eyes and remained nochange in 2 eyes in ICGA. Conclusion TTT is obviously effective in treating CEC.
