UNASSIGNED: To report 2 cases of atypically located, non-nasal colobomas in the pediatric population.
UNASSIGNED: A 3-week-old female neonate with no known past ocular or medical history was diagnosed with temporal iris and chorioretinal coloboma with tractional membranes upon examination under anesthesia and imaging. A 9-year-old female with a history of bilateral sensorineural hearing loss and left mild hydronephrosis presented with a temporal chorioretinal coloboma associated with retinal detachment.
UNASSIGNED: Very few cases of atypically located, non-nasal pediatric colobomas have been reported, and they lack a clear cause or mechanism of formation. Continued documentation of their occurrence and research into their formation at a molecular and embryological level are warranted to better understand their pathogenesis.

UNASSIGNED: This case report discusses the management of a patient with a superior chorioretinal coloboma-associated retinal detachment (RD), including surgical management, along with a review of the literature.
UNASSIGNED: A case report is presented.
UNASSIGNED: A 58-year-old man presented with a chronic RD of the right eye that was symptomatic for approximately 1 year prior to presentation. On examination, he was found to have a macula-off RD associated with superior chorioretinal coloboma. He underwent 23-gauge pars plana vitrectomy with membrane peel, endolaser, and perfluoropropane (14%) gas tamponade. Three months after his surgery, his best-corrected visual acuity in his right eye was 20/250 distance and 20/80 near, and his retina remained attached.
UNASSIGNED: This case report describes surgical management of a superior chorioretinal coloboma-associated RD.

In this clinical picture, a case of atypical superonasal iris, lens and retino-choroidal coloboma has been described in a 16-year-old boy who complained of defective vision since childhood in the right eye. The right eye showed a coloboma in the supero-nasal region of the iris and lens with fundus showing a superonasal fundal coloboma sparing the disc. No separation of the intercalary membrane was noted. This case adds to a very small number of published cases with superior iris and retinochoroidal colobomas.

OBJECTIVE: To report a case of canine atypical chorioretinal coloboma where ophthalmoscopic, fluoroangiographic and optical coherence tomography characteristics are described.
METHODS: A 2-year-old Golden Retriever dog in which routine ophthalmoscopic examination allowed diagnosis of a posterior coloboma on the left eye.
METHODS: Retinography, fluorescein angiography, and optical coherence tomography were performed to characterize the lesion of the left fundus.
RESULTS: Ophthalmoscopy revealed a pigmented circumscribed lesion dorsal to the optic nerve of the left fundus, surrounded by small areas of hyper-reflectivity and retinal vessels with an abnormal pattern. Fluoroangiography revealed a constant hypofluorescence of the defect and a complete altered vascular pattern associated with the coloboma. Optical coherence study demonstrated an important craterlike depression showing an atrophic neurosensory retina, and a lack of retinal pigment epithelium and choroidal tissue.
CONCLUSIONS: Fluoroangiographic and optical coherence tomographic studies of an atypical chorioretinal coloboma in a dog are reported for the first time. Both imaging techniques are of great importance to characterize this type of congenital defects.
