Intraocular surgical procedures in general and filtering surgery in particular, predispose to cataract formation or accelerate pre-existing lens opacification thus the management of a visually significant cataract in a glaucoma patient who has had a previous trabeculectomy is a common clinical challenge, with the possibility that the intraocular surgery might result in filtration failure and lo...

Hyperornithinaemia gyrate atrophy (HOGA) is a rare autosomal recessive disorder in which chorioretinal degeneration occurs with cataracts, myopia, and hyperornithinaemia. We report the case of an 18-year-old female who presented with the typical features of HOGA, including posterior subcapsular cataracts and elevated plasma ornithine. She later developed distorted vision in both eyes owing to w...

We reported a 75-year-old diabetic man, who developed opacification and neovascularization of the posterior capsule after extracapsular cataract extraction and posterior chamber intraocular lens implantation. The patient was treated with two injections of 2.5 mg of intravitreal bevacizumab. The treatment produced an important regression of the posterior capsular new vessels, allowing us to perf...

The first demonstration of transformation (Griffith, 1928) was concerned with type-specific capsular polysaccharides of pneumococci. Such transformations of capsular types usually are accompanied by a change in colony type since most investigators have studied transformation of R cells which produce little or no capsular material. Coiacomitant transformation of capsular and colony type has been...

purpose : to investigate long-term visual outcome and complications after cataract extraction and intraocular lens (iol) implantation in fuchs’ heterochromic iridocyclitis (fhi) methods : in this retrospective study in a private eye clinic in tehran, 25 eyes of 24 patients with fhi who underwent cataract extraction and iol implantation were evaluated based on their visual outcome and intraopera...

Capsular contracture is the most common complication following implant based breast surgery and is one of the most common reasons for reoperation. Therefore, it is important to try and understand why this happens, and what can be done to reduce its incidence. A literature search using the MEDLINE database was conducted including search terms 'capsular contracture breast augmentation', 'capsular...

Study of the capsular genome of pneumococcus has shown that it controls a multiplicity of biochemical reactions essential to the synthesis of capsular polysaccharide. Mutation affecting any one of several biochemical reactions concerned with capsular synthesis may result in loss of capsulation without alteration of other biochemical functions similarly concerned. Mutations affecting the synthes...

PURPOSE To evaluate the perspective of ophthalmology residents in the US about their residency programs and compare the competency of residency programs to international competency levels set by the International Council of Ophthalmology (ICO). METHODS A cross-sectional web-based survey extracted from the ICO published competency standards was sent to program directors of ophthalmology reside...

Accommodation may be restored to presbyopic lenses by refilling the lens capsular bag with a soft polymer. After this accommodative lens refilling prevention of capsular opacification is a requirement, since capsular opacification leads to a decreased clarity of the refilled lens. It has been hypothesized that capsular fibrosis causing the capsular opacification results in increased stiffness o...
