The Ectopia lentis et pupillae is a rare genetic syndrome, congenital, autosomal recessive with variable expression, characterized by ectopia of the lens and the pupil, usually bilateral and symmetrical, but without systemic manifestations. The pathogenesis of this anomaly is still unknown, but there are theories that the change is mesodermal, neuroectodermal, combined or mechanical. This article presents a clinical case of a patient with ectopia lentis et pupillae, describing its clinical and genetic aspects, secondary ocular complications and differential diagnosis.

The iridoschisis is the separation of the brochures of the iris. Rare condition that affects typically both eyes of aged woman. The present study is case report of phacoemulsification in patient with iridoschisis and white cataract. Best corrected visual acuity (BCVA) of the left eye was 0.001. The used technique was stop and chop with the use of four hooks of iris and IOL was a folding three pieces hydrophobic acrylic being introduced inside of the capsular bag. Patient evolved […]

The intraocular lenses have been used in visual rehabilitation after cataract surgery since 1959 with a large success. However, biomaterial changes in the optic zone of these lenses have been described in the last years reducing visual acuity after surgery. This case reveals a significant snowflake opacification of the optic zone of polymethylmethacrylate intraocular lens followed by a discussion about this event and the indication for IOL exchange.

Fuchs’ heterochromic iridocyclits or Fuchs’ Syndrome is a kind of uveitides relatively uncommon. Affect equally both genders, between 20-45 years old, in the classic features include a chronic unilateral nongranulomatous inflammation in anterior uvea, insidious onset, low-grade in activity, and unresponsive to corticosteroid therapy. Usually has a good prognosis, except for the development of cataract and glaucoma, pathologies associated with syndrome. In this case, there are a male pacient, 68 years, with glaucoma as the first manifestation of the Fuchs’Syndrome.

Neuroblastoma is the most frequent extracranial solid tumor among pediatric patients, and orbital metastatic disease is not uncommon in these children. Physical signs as a consequence of orbital metastases, such as proptosis and periorbital ecchymosis, frequently are encountered. However, subsequent blindness is rare. We report on a 2 year old child with orbital metastasis of a primary neuroblastoma in the left suprarenal region that evaluated to a bilateral blindness. We discuss the importance of the early diagnosis, and more studies […]

This paper describes the intraoperative refraction for intraocular lens (IOL) power calculation. Report a case of a 67 year-old male patient reporting a progressive loss of visual acuity in the left eye (OS). Examination revealed best corrected visual acuity (BCVA) of 20/60 (-21,50 -4,00 X 170) related to adherence of silicone oil to the IOL optic. IOL exchange was proposed, however biometry was variable and doubtful. Intraoperative refraction confirmed the IOL power and the patient underwent uneventful IOL explantation and […]

The adult lacrimal obstruction can be congenital or acquired. In the case of the acquired form, the etiology classifies in not-specific (it involves the coating epithelium and/or the vascular plexus submucosae of the lacrimal duct) and specific (infections, inflammations, tumours and iatrogenies). The diagnosis is established by means of the anamnesis and clinical evaluation based on semiology of the lacrimal sack. The patients with lacrimal obstruction present epiphora, acute pains and swelling, mostly in the region of the lacrimal sack […]

The acute retinal necrosis is a rare and devastating necrotizing retinitis, which can be caused by the herpes simplex virus type 1 or 2. It typically affects healthy patients of all ages. This study report a case of 18 year-old healthy male patient, with the the diagnosis of the acute retinal necrosis due to herpes simplex, and presents its clinical and ultrassonographic features. The acute retinal necrosis results in endofthalmitis because of lack of early diagnosis and therapy.
