Background: Subluxation of the crystalline lens has various surgical management options. In moderate zonular dialysis, capsular bag may be preserved and used for intraocular (IOL) implantation using a tension ring or Cionni Capsular segment. It is technically demanding associated with high incidence complications such as IOL decentration, dislocation, posterior opacification (PCO). Advantages c...

purpose: to compare the outcomes and complications of mitomycin-c (mmc) trabeculectomy and ahmed glaucoma implant (agi) for treatment of aphakic glaucoma following congenital cataract surgery in children £ 16 years of age. methods: in a randomized clinical trial, eligible children were randomly assigned to mmc trabeculectomy or agi. aphakia was due to previous anterior lensectomy and vitrectomy...

BACKGROUND To characterize the causative pathogens and the visual outcomes among patients with endophthalmitis at a large referral center in northeastern Thailand. METHODS All cases of infectious endophthalmitis treated between 1983 and 2007 were reviewed retrospectively. The patient data - including age, sex, history of ocular injuries, previous treatment and duration of the symptoms - were ...

I ntraocular foreign bodies (IOFBs) present unique surgical challenges, particularly when the posterior segment is involved. Risk factors for IOFB after ocular injury include youth, male gender, work-related injury, metallurgy, and battlefield or blast injury. If either traumatic endophthalmitis or traumatic cataract is present, there should be a high index of suspicion for IOFB, and imaging st...

PURPOSE The purpose of this study was to investigate the serum hypercoagulability state and common viral and protozoan infections in Coats' disease versus a normal control group. MATERIALS AND METHODS In this comparative case series, 22 consecutive patients with Coats' disease and 19 non-Coats' patients undergoing lensectomy for congenital, traumatic, or senile cataract between January 2011 a...

AIM To assess the refractive outcome of clear lensectomy combined with piggyback intraocular lens implantation in highly hyperopic patients. METHODS This case review included 19 eyes of 10 patients with high hyperopia and axial length less than 21mm. Intraocular lens power was calculated for emmetropia using the Holladay II formula in 17 eyes, and SRK/T formula in 2 eyes following clear lens ...

Ectopia lentis continues to be a therapeutic challenge for ophthalmologists. It can occur as an isolated condition, after ocular trauma, in association with other ocular disorders, as part of a systemic mesodermal disease or as a complication of general metabolic disorders. Minimal subluxation of the lens may cause no visual symptoms, but in more advanced cases serious optical disturbances aris...

Congenital fibrovascular pupillary membrane (1-4) is an unilateral ocular change of the anterior segment (Figure 1). This abnormality was first reported by Cibis et al. in 1986. In some cases, progressive miosis, posterior embryotoxon and abnormality of the anterior chamber angle have been documented. Pupillary membrane might not be adhered to crystalline, or it can also be associated with ante...

PURPOSE To present a case of Weill-Marchesani syndrome with corneal endothelial dysfunction due to anterior dislocation of a spherophakic lens and corneolenticular contact. METHODS A 17-year-old woman presented with high myopia and progressive visual disturbance. She was of short stature and had brachydactyly. Her initial Snellen best corrected visual acuity (BCVA) was 20/50 (-sph 20.50 -cyl ...

In Xenopus laevis tadpoles, wounding of the outer cornea failed to initiate lens regeneration. If both the outer and inner corneas were wounded or if the lens was dislocated, lens regeneration was initiated but failed to continue beyond stage III. However, lensectomy followed by re-implantation of the lens resulted in the regeneration of a fully differentiated lens in several cases, despite the...
