Ultrasonographic evaluation of transition from normal to ectatic area: A comparison between myopic staphylomata and coloboma
نویسندگان
چکیده
Choroidal coloboma and posterior staphyloma are two clinically distinct entities, with choroidal excavation being a unifying feature. They are associated with early onset cataract which can make ophthalmoscopy difficult. This report studies the transition between the normal and ectatic area in these cases with ultrasound. We evaluate "posterior hump" as a sign of differentiation between these two conditions.

Microcornea with myopia.
THE normal corneal horizontal diameter is 12 mm. and any value less than 11 mm. is considered to represent the condition of microcornea (Mann, 1958). The term should be applied only to eyes which are normal except for a small cornea. Corneal curvature is increased so that the corneal refraction is usually great, but associated myopia of varying degrees has been observed by Biro (1935), Puglisi-...

متن کاملPeripapillary coloboma simulating double optic disc.
EDITOR,—Doubling of the optic disc is rare and can manifest as true or pseudo doubling. A 64 year old man was referred by his physician who noted “a clear area between each optic disc on both sides” during a routine check. Visual acuities and anterior segments were normal. Funduscopy revealed an appearance simulating double optic discs on each side. The right eye showed a 2 disc diameter (DD) s...
متن کاملUltrasonographic Evaluation of Placenta Thickness and Fetal Cord Cross Section in Gestational Diabetes Mothers Compared to Control Group
Background The metabolic enhancement resulted from hyperglycemia in gestational diabetes leads to macrosomia, which can affect the placenta. In gestational diabetes mellitus (GDM) pregnant women, the thickness of placenta and cord diameter can change at ages prior to treatment initiation. Therefore, this study was conducted to examine the thickness of placenta an...
متن کاملEvaluation of various factors relating to intraocular pressure and C/D ratio
Introduction: Intraocular pressure (IOP) is determined by three factors: the rate of aqueous humor production by the ciliary’s body, the resistances to aqueous out flow across the trabecular meshwork and the level of episcleral vessel pressure. IOP varies with a number of factors, including: age, sex, race, systemic disease and diurnal variation. The purpose of this study is measurement of IO...
