Background: Systematization of characteristics and morphological changes in the retina, and understanding its role in occlusive diseases involving retinal vessels can contribute to research on the dynamic of the pathological process and to improved understanding of disease treatment. Objective: To research the basic morphometric and structural indicators of the macular region of the retina in patients with central retinal vein occlusion (CRVO). Settings and Design: Ufa Eye Research Institute, retrospective case series. Methods: The basic morphometric and structural indices of […]

The retinoblastoma is known as the most common intraocular malignancy of the childhood. In addition to other diagnostic methods the optical coherence Tomography (OCT) may be considered an important tool in the evaluation of selective involvement of the retina by small and medium sized tumors at the posterior pole of the eye. The authors present two cases of retinoblastoma in which the OCT was able to demonstrate the morphological features of the tumor at diagnosis and the structural changes in […]

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 […]

Optic disc pit and macular microhole are two rare pathologies with an extremely low likelihood of coexistence, this paper will report an association of both pathologies in the same eye with the purpose of analyzing clinical manifestations, tests, angiography, OCT, retinography, biomocroscopy, treatment outcome and the connection between the optic disc pit and macular microhole.

Malignant glaucoma is an entity characterized by intraocular pressure (IOP) with a shallow anterior chamber in the presence of a patent peripheral iridectomy. In its classic form, malignant glaucoma is rare but one of the most serious complications of fistulizing surgery in patients with narrow angle or angle closure glaucoma. In this case we have a female patient who developed crisis of ciliary block glaucoma (malignant) during performance of circadian IOP curve with dynamic contour tonometer.

PURPOSE: To determine the reproducibility of the peripapillary retinal nerve fiber layer thickness and optic nerve head parameters measured with the optical coherence tomography (SD-OCT) in normal eyes. METHODS: Thirty-four eyes of 34 healthy patients were included in the study. The Cirrus OCT optic disc cube 200×200 protocol was used to obtain three scans from each eye to evaluate the reproducibility. Intraclass correlation coefficient (ICC) was calculated for the measurements of retinal nerve fiber layer thickness and optic nerve head […]

The detachment of Descemet’s membrane can be a serious complication following cataract surgery, leading to severe corneal edema and reduced visual acuity. This report describes an unusual case of Descemet’s membrane detachment 6 months after successful phacoemulsification, documented by anterior segment optic coherence tomography (OCT; RTVue, Optovue). The eye was treated successfully with pneumatic descemetopexy and transcorneal suturing, with reattachment of Descemet’s membrane. This report should alert physicians that delayed corneal edema can be related to late-onset Descemet’s membrane detachment, […]

A case of unilateral visual loss and right eye presenting intense pre-orbital bleeding was described in patient 80 years old, after upper and lower bilateral blepharoplasty surgery. Ophthalmologic examination showed clinical profile of posterior ischemic optic neuropath with superior hemianopsia and magnetic resonance imaging (MRI) of normal orbit. Comments are made on possible mechanism involved in the process as well as analysis on the evolution of the retinal nerve layer by optical coherence tomography.
