purpose : to report a case of posterior keratoconus with atypical ocular findings case report : an 8-year-old boy was referred to our clinic with the chief complaint of blurred vision in his right eye. the patient had no history prior ocular surgery of trauma. her family history was also unremarkable. comprehensive ocular examination was performed. results : the patient's best spectacle co...

purpose: to determine the sensitivity and specificity of posterior corneal elevation in discriminating keratoconus and subclinical keratoconus from normal corneas by galilei and orbscan ii diagnosed on the basis of topography. methods: three groups (keratoconus, subclinical keratoconus and normal) were evaluated with galilei and orbscan ii and results were compared to those obtained by gold sta...

PURPOSE To compare the anterior and posterior corneal elevation maps between keratoconus-suspect eyes and normal eyes. SETTING Rothschild Foundation, AP-HP, University Paris VII, Hôpital Bichat Claude Bernard, Paris, France. METHODS The anterior and posterior corneal surface elevations were analyzed and compared in 60 normal myopic patients and 48 keratoconus-suspect patients. The anterior ...

PURPOSE To determine the corneal elevation values and keratoconus indices in the 40- to 64-year-old population and their changes with aging. METHODS The 6311 invitees of this study were selected through random cluster sampling, and 5190 of them participated in the study (response rate = 82.2%). Here, we analyzed results of Pentacam acquisitions in 4148 respondents. Cases of keratoconus and fo...

Purpose: To report a rare case of bilateral circumscribed posterior keratoconus in microcornea associated with unilateral irido-fundal coloboma. Method: A case of bilateral circumscribed posterior keratoconus associated with unilateral irido-fundal coloboma presented to us with complaints of diminution of vision in both eyes since birth. The patient had undergone renal transplant for end stage ...

A case of acquired posterior keratoconus is presented. As in developmental cases the vision was moderately reduced and the condition was not progressive. Posterior keratoconus is usually developmental in origin, but trauma has been implicated in some cases.

PURPOSE To assess the correlation between keratoconus severity and intereye asymmetry of pachymetric data and posterior elevation values and to evaluate their combined accuracy in discriminating normal corneas from those with keratoconus. METHODS This study included 97 patients: 65 subjects with bilateral normal corneas (NC) and 32 with keratoconus (KC). Central corneal thickness (CCT), thinn...

BACKGROUND Posterior keratoconus is a rare cause of a corneal opacity in an infant. It is characterized by thinning of the posterior cornea without ectasia of the anterior cornea. Imaging of this condition with anterior segment optical coherence tomography (AS-OCT) has not been reported in the literature. CASE PRESENTATION A six week old African-American male presented with a congenital corne...

Objective: To assess sensitivity of corneal volume, asphericity, and D index in early diagnosis keratoconus. Methods: A cross-sectional analytical study, carried out between December 2018 October 2020, which analyzed the medical records 39 patients (78 eyes) diagnosed as keratoconus by a single specialist, using criteria Belin-Ambrosio Enhanced Ectasia Display. The collected data were anterior ...
