PURPOSE The purpose of this study was to report on a posterior segment coloboma manifesting unusual morphology as determined by high-speed, ultrahigh-resolution optical coherence tomography imaging. METHODS A 47-year-old woman with bilateral colobomas was evaluated by fundus examination and high-speed, ultrahigh-resolution optical coherence tomography imaging. RESULTS Imaging with high-spee...
purpose: to assess the frequency and type of associated malformations and chromosomal anomalies among patients with anophthalmia, microphthalmia, and coloboma in sistan and baluchestan province. methods: patients with a clinical diagnosis of anophthalmia, microphthalmia, or coloboma were examined to find any anomaly in craniofacial, muscle-skeletal, cardiac, neurologic and urogenital systems. a...
Purpose: To measure choroidal thickness in normal subjects, using optical coherent tomography (OCT) in Rasht. Methods: Normal subjects older than 20 years, living in Rasht, were selected through systematic random sampling by using the city telephone directory. The subjects underwent comprehensive eye examinations for inclusion in the study. Then, choroidal thickness was measured in both eyes by...
The aim of this study was to analyze the techniques for intraocular lens (IOL) implantation in patients with coloboma of the iris. A retrospective cohort study was used to analyze the degree of iris coloboma and the characteristics of the crystalline lens in 56 patients with iris coloboma. The patients with a lesser degree of coloboma of the iris and an intact lens capsule were treated by iris ...
Coloboma literally means defect. Ocular coloboma of the eyes is an extremely rare congenital developmental defect, which constitute one of important causes of visual impairment and blindness in the pediatric age group. Reported incidence of ocular coloboma is 0.5 to 7.5 per 10, 000 live births. Authors report an interesting case syndromic variety of ocular coloboma, where the upper eyelid colob...
Comparison of Choroidal Thickness in Psoriasis and Control Groups Using Optical Coherence Tomography
Background and Objective: One of the most common extracutaneous complications in psoriasis patients is ocular complications, which is controversial concerning its effect on choroidal thickness. This study aimed to compare the psoriasis patients with healthy individuals in terms of the thickness of the choroidal layer using the optical coherence tomography technique. Materials and Methods: In t...
OBJECTIVE To describe the incidence, ocular findings, and systemic associations of coloboma in a population-based cohort of children. METHODS We retrospectively reviewed the medical records of pediatric (aged <19 years) patients diagnosed as having ocular coloboma from January 1, 1968, through December 31, 2007, as residents of Olmsted County, Minnesota. RESULTS Thirty-three children were n...
We report an epidemiological and genetic study attempting complete ascertainment of subjects with microphthalmia, anophthalmia, and coloboma (MAC) born in Scotland during a 16 year period beginning on 1 January 1981. A total of 198 cases were confirmed giving a minimum live birth prevalence of 19 per 100 000. One hundred and twenty-two MAC cases (61.6%) from 115 different families were clinical...
