ABSTRACT
Objective: To evaluate the changes in anterior segment parameters after neodymium-yttrium-aluminum-garnet [Nd:YAG] laser capsulotomy in 1-piece and 3-piece IOLs
Methods: In an institution, 65 eyes of 65 consecutive pseudophakic patients with posterior capsule opacification underwent Nd:YAG laser capsulotomy. The patients were divided into two groups according to the IOL type. Group-1 consisted of 35 subjects with 1-piece IOL and Group-2 consisted of 30 subjects with 3-piece IOL. Anterior segment parameters were measured with the Sirius rotating camera before, one week and one month after Nd:YAG laser capsulotomy
Results: Mean age was 72.3+/-5.2 years in 1-piece IOL and 72.3+/-6.8 years in 3-piece IOL. There were no statistically significant differences before capsulotomy for IOP, axial length, spherical equivalent, anterior chamber depth, central corneal thickness, anterior chamber angle and anterior chamber volume between two IOL groups. BCVA improved after capsulotomy in both groups [p=0.001]. Both IOL groups had statistically significant myopic shift compared with the baseline values [P= 0.03 and P=0.01 resp.]. Both IOL groups had statistically significant decrease in ACD, from baseline to the 1st week and 1st month [p=0.04 and 0.03 resp.]
Conclusion: To achieve the highest percentage of refractive and anterior segment stability surgeons may prefer to implant the 1-piece IOL design
ABSTRACT
Diabetic macular edema [DME], one the most prevalent causes of visual loss in industrialized countries, may be diagnosed at any stage of diabetic retinopathy. The diagnosis, treatment, and follow up of DME have become straightforward with recent developments in fundus imaging, such as optical coherence tomography. Laser photocoagulation, intravitreal injections, and pars plana vitrectomy surgery are the current treatment modalities; however, the positive effects of currently available intravitreally injected agents are temporary. At this point, further treatment choices are needed for a permanent effect. Sources of data selection: The articles published between 1985-2015 years on major databases were searched and most appropriate 40 papers were used to write this review article
ABSTRACT
Radiation retinopathy remains a devastating cause of visual morbidity in patients undergoing radiation for globe, orbit, and head and neck malignancies. A 65-year-old female was admitted with the complaint of low vision in the right eye for two months. Best corrected visual acuity was 20/32 in the right eye and 20/25 in the left eye. Slit lamp examination was normal in both eyes. Fundoscopic examination revealed perifoveolar hard exudates, paramacular microhemorrhages, telangiectasias, and macular degeneration in both eyes. Fundus florescein angiography showed enlargement of the foveal avascular zone, perifoveal capillary telangiectasia, and widespread venous beading bilaterally. Optical coherence tomography revealed bilateral cystoid macular edema. The prediagnosis of diabetic retinopathy was not confirmed because of the absence of diabetes mellitus after endocrinologic evaluation. Detailed medical history explored external beam radiotherapy to the head and neck region for nasopharyngeal cancer 10 years ago. The ultimate diagnosis was radiation retinopathy
