background: Ocular coloboma is the product of an error in the fetal fissure closure, normally occurring between the fifth and sixth weeks of gestation blank">[1]. It may involve the cornea, iris, zonula, ciliary body, choroid, retina and optic nerve. The incidence of this syndrome is 0.7 per 10,000 live-births blank">[1]. The aim of this observation is to present the first case of bilateral coloboma of the iris blank">[1]. This case was associated with an ametropia causing a decrease in visual acuity. Case Presentation: This was a clinical observation concerning a young 12-year-old patient who consulted for blurring of vision which had progressed for approximately 2 years. The ophthalmologic examination revealed an ametropia with a bilateral notch of the pupillary rim suggesting a bilateral coloboma. There was no association with another coloboma such as chorioretinal coloboma which is quite common and is accompanied frequently by visual symptoms. Conclusion: A visual impairment of the child can indicate ametropia. However, other congenital anomalies can be discovered as was the case in this clinical observation.

Open Journal of Ophthalmology 2021年第4期11卷 325-331页

background: Druses of the papilla constitute abnormal deposits of calcified hyaline material at the level of the head of the optic nerve. They can be superficial or deep. Aim: The aim of this study is to show the utility of ocular ultrasound in ophthalmology in underdeveloped countries for the characterization of optic disc druse. Case Presentation: Our study relates to a clinical observation of buried papillary druses diagnosed by ocular ultrasound. The ophthalmologic examination revealed an aspect of false papillary edema in the fundus. The ocular ultrasound revealed hyperechogenic deposits buried in the papillary margins, which suggests the deep papillary druses. Conclusion: Ocular ultrasound still has a prominent place in the diagnosis of certain eye conditions despite the new sophisticated means available to ophthalmology to date.
