Four members of a three-generation Czech family with early-onset chorioretinal dystrophy were shown to be heterozygous carriers of the n.37C>T in MIR204. The identification of this previously reported pathogenic variant confirms the existence of a distinct clinical entity caused by a sequence change in MIR204. Chorioretinal dystrophy was variably associated with iris coloboma, congenital glaucoma, and premature cataracts extending the phenotypic range of the condition. In silico analysis of the n.37C>T variant revealed 713 novel targets. Additionally, four family members were shown to be affected by albinism resulting from biallelic pathogenic OCA2 variants. Haplotype analysis excluded relatedness with the original family reported to harbour the n.37C>T variant in MIR204. Identification of a second independent family confirms the existence of a distinct MIR204-associated clinical entity and suggests that the phenotype may also involve congenital glaucoma. 相似文献

AIM: To assess the projected needs for cataract surgery by lens opacity, visual acuity, and patient concern. METHODS: Data were collected as part of the Melbourne Visual Impairment Project, a population based study of age related eye disease in a representative sample of Melbourne residents aged 40 and over. Participants were recruited by a household census and invited to attend a local screening centre. At the study sites, the following data were collected: presenting and best corrected visual acuity, visual fields, intraocular pressure, satisfaction with current vision, personal health history and habits, and a standardised eye examination and photography of the lens and fundus. Lens photographs were graded twice and adjudicated to document lens opacities. Cataract was defined as nuclear greater than or equal to standard 2, 4/16 or greater cortical opacity, or any posterior subcapsular opacities. RESULTS: 3271 (83% response) people living in their own homes were examined. The participants ranged in age from 40 to 98 years and 1511 (46.2%) were men. Previous cataract surgery had been performed in 107 (3.4%) of the participants. The overall prevalence of any type of cataract that had not been surgically corrected was 18%. If the presence of cataract as defined was considered the sole criterion for cataract surgery with no reference to visual acuity, there would be 309 cataract operations per 1000 people aged 40 and over (96 eyes of people who were not satisfied with their vision, 210 eyes of people who were satisfied with their vision, and three previous cataract operations). At a visual acuity criterion of less than 6/12 (the vision required to legally drive a car), 48 cataract operations per 1000 would occur and people would be twice as likely to report dissatisfaction with their vision. CONCLUSIONS: Estimates of the need for cataract surgery vary dramatically by level of lens opacity, visual acuity, and patient concern. These data should be useful for the planning of health services. 相似文献

Before the introduction of modern ophthalmic surgical technology following World War II, cataract extraction was easier and
safer to perform if the cataract was far advanced (mature) and both eyes were involved. The surgeon was constrained from early
surgery by the frequency of severe complications, the long convalescent period, and the distortions of aphakic glasses. Now
it is easier to perform phacoemulsification and implant lenses in the early stages of cataract formation when the nucleus
is soft and the posterior lens capsule has not been weakened with age. Also, modern small-incision extracapsular cataract
extraction has a low rate of complications and a short convalescent period. It is feasible to extract a clear lens or one
with minimal opacifications and have a grateful patient. The surgeon is capable of improving the refractive state of the eye
by selecting the power of the intraocular lens. These facts have led to instances where cataracts have been extracted that
were responsible for minimal or no symptoms.

Purpose: To characterise the association between lens phacoemulsification and the development of macular edema. Methods: We studied 15 patients who underwent lens phacoemulsification in our clinic between January and April 1998 performed by
the same surgeon. Ultrasound power and cumulative time was noted. Follow-up was performed at 1 day, 1 week, 1, 3 and 6 months
after operation. On each visit corneal thickness, best corrected visual acuity, biomicroscopy and fluorescein angiography
were performed. Patients with systemic diseases and/or retinal diseases were not included. Results: Visual acuity was inversely related to the amount of energy delivered during phacoemulsification. In patients who had received
more than 1 Joule of energy, fluorescein angiography revealed a higher incidence of blood retinal barrier breakdown. Corneal
thickness was not correlated with the ultrasound energy used. Conclusions: Excessive use of power during phacoemulsification may hamper the postoperative evolution of cataract surgery.
