Current review focus on hidden links between glaucoma, contact lenses and Ocular Surface Disease (OSD), in glaucoma the most important treatment is the control of progression through targeted pharmaceutical protection, keeping low intraocular pressure, by prescribing ophthalmic medications.

Such factor is the decrease of tear production with increasing of age and numerous changes in the composition of the tear film. At the same time, elderly often suffer from other pathological diseases that encourage the development of dry eye and eye irritations. Adding the anti-glaucoma eye drops containing preservatives along with the constant use of contact lenses, we are led to a serious multifactorial dry eye condition.

Introduction: The Non hodgkinien lymphma (NHL) orbital location is a rare tumor, difficult to diagnose. The mantle cell lymphoma represents 6% of cases of LNH B. We report a patient of 60 years with bilateral exophthalmia revealing a mantle cell lymphoma. Clinical Observation: A man of 60 years ran for ophthalmological emergencies in an array of orbital cellulitis of the right eye. This swelling was that day, painful, inflammatory, axile, irreducible, and non-pulsatile, with limited horizontal movement of the eyeball. In general terms, the patient has axillary lymph nodes and supraclavicular without splenomegaly. A biopsy of the orbital mass produced by trans-conjunctival, concluded in a non-Hodgkin lymphoma B type mantle (CD20 +, CD5 +, cyclin D1 +). The assessment of extension realized in the Hematology Clinic department shows that this is a mantle cell lymphoma NHL B stage (nodes above and below the diaphragm, bilateral eyelid damage, spinal cord and location). After 3 treatments Rituximab-CHOP and DHAP-Rituximab treatments 3, obtaining a complete remission. Discussion: The mantle cell lymphoma represents about 6% of NHL. Its incidence is estimated between 0.07 and three cases per 100 000 population per year. The geographical area and ethnicity shows a higher frequency in Caucasians than in African Americans. Ocular involvement in the NHL is a rare event, as evidenced by the limited number of cases reported in the literature. It may be opening that is the case of our patient, or alter the course of lymphoma known. Conclusion: The eye location of mantle cell lymphoma is a rare entity. The clinical picture of this location can be misleading, particularly that of orbital cellulitis. The tumor biopsy confirms the diagnosis. Despite the treatment regimens, the prognosis of this type of lymphoma is reserved.

Objective: To determine the prevalence of DR in public health care units of São José do Rio Preto-SP-Brazil. Material and Methods: Population-based cross-sectional study that included 710 diabetic patients. All patients underwent an eye examination by indirect ophthalmoscope to check for any signs of DR. Participants were also interviewed and examined to determine their demographic characteristics, medical conditions and the realization of previous fundoscopic eye examination. Statistical studies were done with t-Student test, Fisher test or chi-square test. Results: Among 710 screened patients, 112 had some degree of diabetic retinopathy, and the overall standardized prevalence of any retinopathy was 16,3%, including 90 (80,4%) with non-proliferative and (22) 19,6% with proliferative diabetic retinopathy. Conclusions: The prevalence of DR in São José do Rio Preto is 16,3%. The main risk factors associated with DR were time of disease and glicemic control. Type of DM and nephropathy were considered secondary risk factors. The presence of high blood pressure, in this study, was not a risk factor associated with DR.

Introduction: PAMM, recently emerged retinal pathology involving preferentially deep retinal capillary system (ICP and DCP) where impaired blood flow occurs, and particularly anatomical and physiological watershed zone is affected (INL and OPL). Resultant ischemia is presented clinically with sudden drop of vision and manifested as band like hyperreflective lesions on SS OCT B scans. SS OCTA with Enface and Retinal flow maps have delineated ischemic lesions within middle retina and exhibited characteristic findings that may help in understanding the pathophysiology behind this entity. Purpose: To highlight PAMM diagnostic features on Optical Coherence Tomography Angiography and Enface, and to emphasize on their major role in detecting and assessing this condition. Methods: This is a retrospective study reviewing two clinical cases presented to our facility with sudden decrease in vision in one eye. DRI OCT Triton (Topcon Corporation, Tokyo, Japan) was employed. In addition to generating high quality conventional cross sectional B scan images, Enface C scans and three dimensional angiography images were obtained at different retinal levels. High-resolution color fundus imaging, Fluorescein Angiography (FA) and Fundus Auto fluorescence (FAF), and Enface in conjunction with OCTA were all used in the two cases. Detailed history, full comprehensive Eye exam was done, appropriate thorough systemic workup was performed; baseline blood tests (CBC, KFT, LFT, UA), coagulation profile (INR, APTT, D Dimer) with blood test for sickle cell (SC), and autoimmune profile. Results: In both cases, OCTA and Enface revealed multiple findings of PAMM during the acute phase of presentation. OCTA provided evidence of DCP ischemia by showing perfusion defects, or capillary dropout. Enface C scans visualized fern-like ischemic distribution at the level of DCP. Discussion: The use of OCTA in conjunction with Enface OCT has proved superior to other imaging modalities in identifying and diagnosing PAMM. It is anticipated that such imaging techniques may provide new insights for middle and deep retinal ischemic pathologies including PAMM which may have a constellation of imaging findings in the near future for its detection, diagnosis, classification, and perhaps management!
简介:PAMM，最近出现的视网膜病理，优先涉及视网膜深部毛细血管系统(ICP和DCP)，血流受损，特别是受影响的解剖和生理分水岭(INL和OPL)。由此导致的缺血在临床上表现为视力突然下降，在SS OCT B扫描上表现为带状高反射病变。带有Enface和视网膜血流图的SS OCTA描绘了视网膜中部的缺血性病变，并展示了可能有助于理解该实体背后的病理生理学的特征性发现。目的:强调PAMM在光学相干断层血管造影和Enface中的诊断特点，并强调其在检测和评估该疾病中的主要作用。方法:回顾性分析两例单眼视力突然下降的临床病例。采用DRI OCT Triton (Topcon Corporation, Tokyo, Japan)。除了生成高质量的常规横断面B扫描图像外，还获得了不同视网膜水平的Enface C扫描和三维血管造影图像。高分辨率彩色眼底成像，荧光素血管造影(FA)和眼底自动荧光(FAF)，以及Enface联合OCTA。详细的病史，全面的眼科检查，适当彻底的系统检查;基线血液检查(CBC、KFT、LFT、UA)、凝血特征(INR、APTT、D二聚体)、镰状细胞(SC)血液检查和自身免疫特征。结果:在这两例病例中，OCTA和Enface在急性期均显示多发性PAMM。OCTA通过显示灌注缺陷或毛细血管脱落提供DCP缺血的证据。Enface C扫描在DCP水平显示蕨类样缺血分布。讨论:OCTA联合Enface OCT在识别和诊断PAMM方面优于其他成像方式。预计这种成像技术可能为包括PAMM在内的中深部视网膜缺血性病变提供新的见解，这些病变在不久的将来可能会有一系列的影像学发现，用于其检测、诊断、分类和治疗!

Introduction: Posterior lenticonus is a rare ectasia of the posterior capsule of the lens and has a prevalence of 1-4/100,000 and is associated with crystalline opacity in 14% of unilateral cases and 9% of bilateral cases. Depending on the degree of opacity and visual impairment, there is a risk of developing amblyopia but the effect on vision is extremely variable. We report two different treatment approaches to the disease. Case Report: The first case is a 10 months male patient with Down syndrome attended for evaluation of cataract with good fixation and no strabismus. Inicially a non surgical treatment was chosen but later he developed an agressive behavior and a posterior lenticone associated with posterior polar cataract was observed, which lead to the decision of a surgical treatment. The second case is a 7 years old patient with history of low visual acuity and posterior polar cataract in the left eye associated with posterior lenticonus discretely displaced superiorly. He was treated with tropicamide and oclusion of the right eye for thirty days. Discussion: The two cases shows how is it possible to manage posterior lenticonus with surgical ou clinical treatments. There is a tendency for patients who underwent cataract surgery to have a better visual acuity improvement compared with patients who did not have surgery, however this data was not statistically significant. Conclusion: The ophthalmologist should be able to recognise this finding during examn and decide wich treatment, surgical or clinical, will bring the best visual outcome for his pacients.

Radial relaxation retinectomy followed by gas (C3F8 14%) tamponade usage has been applied to eyes experiencing retinal detachment accompanied by PVR of grade C1, C2, C3 and D1. In this method, geometrical boundaries of radial retinectomy are set up as to protect blood vessels, papil and macula. So far, out of totally 60 eyes who have received the treatment of this method, 2 eyes achieved 70% vision improvement, 4 eyes achieved 60%, 9 eyes achieved 50%, 16 eyes achived 40%, 14 eyes achieved 30%, 9 eyes achived 20%, and 6 eyes experienced 10% vision improvement. This new method provides an alternative relaxation retinectomy which is relatively fast and inexpensive and yields good results.

In this method, geometrical boundaries of radial retinectomy are set up as to protect blood vessels, papil and macula. So far, out of totally 60 eyes who have received the treatment of this method, 2 eyes achieved 70% vision improvement, 4 eyes achieved 60%, 9 eyes achieved 50%, 16 eyes achived 40%, 14 eyes achieved 30%, 9 eyes achived 20%, and 6 eyes experienced 10% vision improvement. This new method provides an alternative relaxation retinectomy which is relatively fast and inexpensive and yields good results.","PeriodicalId":92830,"journal":{"name":"Ophthalmology research and reports","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90835580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
