This report describes a rare occurrence of bilateral, spontaneous, nontraumatic hyphema in a 6 weeks old infant, associated with a small, multiple skin lesions. The diagnosis of juvenile xanthogranuloma was confirmed by histopathological examination of the cutaneous lesions. The hyphaema cleared gradually in 2 weeks time with conservative management.
Congenital unilateral fibrosis, blepharoptosis and enophthalmos syndrome is one of the rare forms of congenital fibrosis of extraocular muscles. The nature and cause of such unilateral inflammation leading to fibrosis is unknown. Prenatal orbital penetration has been proposed as a cause of this syndrome. We report a case of this rare syndrome associated with an adjacent sinus tumor.

BACKGROUND: Cataract extraction in a carotid cavernous fistula can cause multiple intraoperative complications during surgery. METHODS: This was a case of bilateral, indirect, carotid, cavernous fistula, type D. The patient developed cataract and visual deterioration in both eyes. We present the difficulties we encountered during extracapsular cataract surgery on one of the eyes. RESULTS: Cataract extraction was done successfully. A self-sealing scleral incision was made. An intraocular lens was implanted. CONCLUSION: Cataract extraction can be done in carotid cavernous fistulas; however, the surgeon should be extremely cautious during the surgery.

PURPOSE: To report the optical coherence tomography (OCT) findings in two cases of presumed congenital simple retinal pigment epithelial (RPE) hamartoma. DESIGN: Observational case report. METHODS: Fundus examination, fluorescein angiography, ultrasonography, and OCT were done on two cases of simple RPE hamartoma. RESULTS: A heavily pigmented solitary macular lesion was noted in the right eye of a 22-year-old man and a 55-year-old woman. The young man had a foveal lesion and a vision of 10/200; the woman with eccentric lesion had a vision of 20/20. The lesions blocked fluorescence on angiogram; sonography showed hyper-reflective nodules. OCT demonstrated full-thickness retinal replacement, complete optical shadowing, and abrupt margins of the lesion in both the cases, and vitreomacular adhesion at the temporal margin of the foveal lesion. CONCLUSIONS: Congenital simple RPE hamartoma may rarely occur at the foveal center, resulting in poor visual acuity. OCT is a useful non-invasive adjunct for diagnosis of this rare tumor and may reveal additional features like vitreoretinal adhesion.
