The intrastromal corneal ring implant surgery is becoming a surgical procedure in the treatment of keratoconus additive in order to minimize and delay the complications inherent to the pathology. Its action consists in the remodeling cornea, flattening and regulating the central corneal surface. Nowadays with the advent of new technologies, there is an important contribution in the diagnosis of keratoconus, with not only diagnosis but also more effective with better monitoring and prognosis of patients with this disorder ectatic. In […]

Adult foveomacular vitelliform dystrophy is a rare pathology. Less than 1% of the reported cases display perifoveal capillary permeability. The three-year follow-up period of the case revealed a rare form, which had not yet been documented. The patient was a 40-year-old female with normal visual acuity, and a minor complaint of metamorphopsia on the left eye. Retinography showed a perifoveal yellowish subretinal area OS.Angiography showed perifoveal leakage OS. Follow up showed that, over 3 years, capillary incompetence disappeared and the […]

To describe the electrophysiological alterations in a very rare case of Oguchi’s disease. A 17-year-old italian girl complaining of night blindness underwent complete ophthalmological exams, including electrophysiological tests. Rod responses were nondetectable in full-field electroretinogram (ERG). The photopic ERG funtions, including the 30 Hz flicker ERG response was normal, while the scotopic b-wave was diminished in amplitude. The electrooculography (EOG) ratios within the normal range were 208% in the right eye and 222% in the left eye. The Mizuo-Nakamura phenomenon […]

Conjunctival cysts in anophthalmic socket may have functional and aesthetic implications for the patients.Among the available treatment options, the use of trichloroacetic acid is relatively recent. Our reported cases showed a good outcome after 30 days of treatment, that was well tolerated by patients, with greater conjunctival tissue preservation.

The authors relate a predominantly hemorrhagic choroidal neovascular lesion from neovascular. Age-related macular degeneration patient case treated with intravitreal ranibizumab therapy. Monthly ranibizumab (six intravitreal injections) displayed a promising response but this limited report is insufficient to guarantee the indication for all predominantly hemorrhagic choroidal neovascular lesion from neovascular age-related macular degeneration. Further studies will be necessary for complete validation of our results for all predominantly hemorrhagic choroidal neovascular lesions from CNV due to AMD.

We present a case of late high progressive astigmatism following penetrating keratoplasty for keratoconus, which was associated with peripheral thinning in the donor-receptor area, which may be recognized as recurrence of ectasia. Treatment was accomplished with Cvintal’s Topoplasty assisted by femtosecond laser for a “top hat”, followed by resuture with peroperative adjustment guided by ceratoscopy.

Saethre-Chotzen syndrome is a very rare congenital syndrome characterized by craniosynostosis. The incidence of it is around 1: 50,000 live births. Intelligence is usually normal, but a few affected individuals may have mild to moderate mental retardation. Children with Saethre-Chotzen syndrome should be evaluated by members of an experienced interdisciplinary team as treatment usually involves many different specialities. The strabismus surgery in these patients is difficult, because they usually have anomalous insertion and misdirection of the extraocular muscles. Imaging techniques […]

The neurofibromatosis type 1 is a autosomal dominant disease which the diagnosis is made based on clinical criteria. Its three main features – neurofibromas, cafe au lait macules and Lisch nodules occur in up to 90% of the pacients until puberty. We documented a clinical case of a young male pacient who had the diagnosis of neurofibromatosis type 1 and family history, describing its clinical aspects and radiological features.
