The Christmas tree cataract is a rare type of lens opacification characterized by deposits of needle-shaped polychromatic cortex deep in the core, that can be isolated or associated with other opacities. We report and record, through photographs, two cases of this type of lens opacity.

The Holmes-Adie syndrome is characterized by the presence of tonic pupil associated with absence or diminution of deep tendon reflexes. In some cases there may be autonomous nerve dysfunction. The mechanism that causes the disorder is not fully known, but is believed to be caused by denervation of the postganglionic supply to the sphincter of the pupil and the ciliary muscle which can occur following viral disease. Typically it affects young adults and is unilateral in 80% of cases, although […]

A Síndrome de Holmes-Adie É caracterizada pela presença de pupila tônica associada à diminuição ou ausência dos reflexos tendíneos profundos. Em alguns casos pode haver disfunção nervosa autônoma. O mecanismo que causa a desordem não é totalmente conhecido, mas acredita-se que seja causada pela desnervação do suprimento pós-ganglionar para o esfíncter da pupila e para o músculo ciliar, que pode ocorrer após doença viral. Tipicamente afeta adultos jovens e é unilateral em 80% dos casos, embora possa se desenvolver no […]

The proximity of the orbital cavities to the air spaces of the face results in the occurrence of orbital infections resulting from sinusitis. Children with debilitated nutritional status are especially vulnerable. Clinically presents the inflammatory signs, and visual acuity deficit, diplopia, ophthalmoplegia and proptosis. Might also lead to severe complications such as cavernous sinus thrombosis and intracranial abscess. These infections can be classified according to their severity. Imaging tests of choice for the diagnosis and planning of cases include axial […]

Ocular allergies encompass a number of inflammatory diseases in the ocular surface which have different hypersensitivity mechanisms and occur in 20% of population. They can be classified as being type I hypersensitivity mediated (PAC, SAC), type I and IV (VKC, AKC) and type IV (BKC, GPC). The most prevalent forms are PAC and SAC. The chronic presentations are mostly related to visual impairment due to remodeling in the ocular surface caused by chronic inflammation. Dry eye disease and keratoconus are […]

The authors make a review of drusenoid retinal pigment epithelium detachments(DPDs), a form of retinal pigment epithelium detachment(PED) that evolves from confluent and large soft drusen.Drusenoidretinal pigment epithelial detachments are a recognized element of the “dry” AMD. Until now, no treatment is indicated in drusenoid PEDs. The authors describe the clinical characteristics of drusenoid retinal pigment epithelium detachments (DPEDs) and make a review of the DPEDs related in the international literature. We related in this revision paper the multimodal advanced […]
