Optical imaging technology of ocular fundus, including fundus fluorescein angiography (FFA), optical coherence tomography (OCT) and fundus autofluorescence (FAF), is growing at an unprecedented speed and scale and is integrating into the routine clinical management of ocular fundus diseases, such as diagnosis, treatment, and mechanism study. While FFA allow us to observe the retinal and choroidal blood circulation, OCT and FAF are non-invasive, fast and quantifiable measurement; such techniques show even more unique advantages and are favored tools. All these retinal imaging technologies, together with a variety of retinal function assessments, bring us into the era of big data of ocular fundus diseases. All of these developments are the challenges and opportunities for the operator and user of these fundus optics imaging technologies. In order to improve its clinical applications and allocate resources rationally, we need to understand the optical properties of these retinal imaging technologies, and standardize diagnosis behavior. This is a continuous learning process needs to continue to explore.
ObjectiveTo analyze the clinical character of uveitis in second hospital of Jilin university. MethodsRetrospectively analyze the clinical data of uveitis patients referred to from Second Hospital of Jilin University from September 2009 to September 2014. According to anatomical location, the manifestation of these uveitis patients were divided into anterior uveitis, panuveitis, intermediate uveitis and posterior uveitis. To discuss the possible causes of these patients according to the general information and relevant clinical laboratory examinations results. ResultsThere were 1215 cases in this study, which included 587 male, accounting for 48.31%; and 628 female, accounting for 51.69%. The ratio of male-to-female was 0.93:1. The range of the age of these patients was from 4 to 91 years old. The mean age of these patients at the onset of these disease was (41.43±14.20) years. Of the 1215 cases, 40 male and 43 female were younger than 20 years. The ratio of male-to-female was 0.93:1; 412 male and 396 female were between 21 and 50 years old. The ratio of male-to-female was 1.04:1; 135 male 189 female were older than 50 years. The ratio of male-to-female was 0.71:1. There were 572 cases of anterior uveitis, accounting for 47.08%; 527 cases of panuveitis, accounting for 43.37%; 52 cases of intermediate uveitis, accounting for 4.28%; 64 cases of posterior uveitis, accounting for 5.27%. 703 cases had etiological diagnosis according to the clinical character and the auxiliary results, accounting for 57.68%. Vogt-koyanagi Haradal (VKH) syndrome, ankylosing spondylitis associated with uveitis and Behçet's disease were the common entity, accounting for 30.44%, 19.77% and 14.22% respectively. ConclusionsThe mean age of these patients in this study was older, compared to other reports. Female patients were more than male, especially in these patients older than 50 years. VKH syndrome, ankylosing spondylitis associated with uveitis and Behçet's disease were the common entities.
The cyclodialysis cleft is a rare disease characterized by ocular hypotony and vision loss. Gonioscopy, ultrasound biomicroscopy and anterior segment optical coherence tomography are used to evaluate the cleft before treatment. The evaluation of cyclodialysis clefts provide a basis for the selection of treatment and the evaluation of effect. Current popular therapeutic approaches for cyclodialysis clefts include medical management, laser photocoagulation, transscleral diathermy, cryotherapy, cyclopexy and so on. Medical treatment is effective in small-size cyclodialysis cleft. But the indications and course of medical treatment remains controversial. Although laser photocoagulation, transscleral diathermy and cryotherapy are effective to treat cyclodialysis clefts in some cases, there are some risks, such as ocular damage, uncertainty about the effect and so on. Cyclopexy is the principal method for cyclodialysis clefts that failed to respond to conservative management, including extraocular cyclopexy, intraocular cyclopexy and cyclopexy under endoscopic. The modified cyclopexy is effective which reduces the surgical risk. For keeping the lens, intraocular cyclopexy and cyclopexy under endoscopic are not suitable. Vitrectomy combined with other method for cyclodialysis is effective for cyclodialysis clefts which combined with serious posterior segment damage.
