5. Retinal nerve fiber layer analysis in cocaine users
  
  Explore ScienceDirect Nov 30 2018 Ophthalmology
  
  Cocaine is a well-known factor of tissue ischemia and may be related to thinning of the inner retinal layers. The present study aimed to evaluate and determine whether cocaine users show retinal nerve fiber layer (RNFL) thinning by means of spectral-domain optical coherence tomography. A group of 17 cocaine users and 18 non-users were recruited for complete ophthalmologic examination. Spectral domain optical coherence tomography (Cirrus OCT) was used to evaluate ...

  Background/aims Split-spectrum amplitude decorrelation angiography for spectral-domain optical coherence tomography has enabled detailed, non-invasive assessment of vascular flow. This study evaluates choriocapillaris and retinal capillary perfusion density (CPD) in diabetic eyes using optical coherence tomography angiography (OCTA). Methods Records of 136 eyes that underwent OCTA imaging at a single institution were reviewed. Eyes were grouped as non-diabetic controls (37 eyes), patients with diabetes mellitus (DM) without diabetic retinopathy (DM ...

  Purpose: To report the results of high-resolution anterior segment optical coherence tomography of patients implanted with a type 1 Boston keratoprosthesis (KPro). Methods: The retrospective study cohort included 11 eyes of 11 patients (average age, 58.4 years; range, 34-83 years). All subjects underwent anterior segment optical coherence tomography at a single posteoperative time point. The main outcome measures were retro-backplate and retro-optic membrane formation, thinning and gap formation of ...

  Structural differences between optic nerve head (ONH) parameters in glaucomatous and non-glaucomatous eyes has been documented, however the association between such parameters in patients with different disease stages is yet to be elucidated. We investigated the relationship between different laminar and prelaminar ONH structures using enhanced depth imaging spectral-domain optical coherence tomography (EDI OCT) in a population with and without glaucoma. In this observational case-control study, we prospectively enrolled healthy ...

16. Combination of anterior segment optical coherence tomography modalities to improve accuracy of rectus muscle insertion location - ScienceDirect
  
  Explore ScienceDirect Jul 13 2017 Ophthalmology
  
  Anterior segment optical coherence tomography (AS-OCT) is useful for locating the extraocular muscle insertion prior to strabismus surgery; however, its accuracy decreases in reoperations. This masked retrospective study investigated whether a combination of AS-OCT modalities improves accuracy. The distance between the corneoscleral limbus and extraocular muscle insertion was measured with AS-OCT, first using the standard grayscale modality alone and then refined with the color modality. The AS-OCT measurement was considered ...
