Purpose To determine the incremental benefit of swept-source optical coherence tomography (SS-OCT) in identifying occult macular disease preoperatively in patients scheduled for routine cataract surgery. Setting Shahzad Eye Hospital, Karachi, Pakistan. Design Prospective case series. Methods Preoperative SS-OCT scans were performed in all patients scheduled to have cataract surgery between January and March 2016. Scans were subsequently reviewed for the presence of macular abnormalities. Patients with clinically detectable retinal pathologies were excluded. Results Of the 179 eligible patients, 155 were included in the study. Macular pathology was noted in 17 patients (10.9%). The most commonly identified conditions were age-related macular degeneration (n = 5), idiopathic epiretinal membrane (n = 4), and vitreomacular interface abnormalities (n = 4). Other abnormalities included cystoid macular edema (n = 2) and ellipsoid zone abnormalities (n = 2). Media opacities precluded interpretation of 9 scans (4.7%). Conclusions Swept-source OCT was an effective noninvasive modality for detecting macular structural abnormalities, especially in the presence media opacities. Optical coherence tomography imaging should be considered as an adjunct to routine dilated fundus examination for macular evaluation, particularly if premium intraocular lenses are being considered.

Abstract Cataract surgery is one of the most common procedures performed worldwide. It is also one of the oldest. Alongside advancements in cataract surgical techniques have been improvements in intraocular lens replacement technology. Cataract surgery may be considered among the most successful treatments in all of medicine. This article discusses the fascinating evolution of cataract surgery, from the earliest approach of couching to modern day phacoemulsification and lens replacement.

Purpose. To report choroidal thickness and volume in healthy eyes using swept source optical coherence tomography (SS-OCT). Methods. A prospective observational study of 122 patients examined with swept source OCT (DRI-OCT, Topcon, Japan). In each eye, we performed 256 horizontal scans, 12 mm in length and centered on the fovea. We calculated choroidal thickness manually with a built-in caliper and automatically using DRI-OCT mapping software. Choroidal volume was also automatically calculated. ...

Abstract To determine choroidal thickness (CT) profile in a healthy population using swept-source optical coherence tomography (SS-OCT). This was a cross-sectional, noninterventional study. A total of 276 eyes (spherical equivalent ± 3 diopters [D]) were scanned with SS-OCT. Horizontal CT profile of the macula was created measuring subfoveal choroidal thickness (SFCT) from the posterior edge of retinal pigment epithelium (RPE) to the choroid-sclera junction. Three determinations were performed a...

The choroid provides up to 70 % of blood and oxygen to the eye. Pathological changes of this vascular tissue may lead to malnutrition of the retina and therefore be involved in the pathogenesis of numerous retinal disorders. Swept source optical coherence tomography (SS-OCT) is a new development of a non-invasive imaging technique that uses a tunable laser source with a higher wavelength light than conventional spectral domain OCT (SD-OCT). This enables visualisation of tissues below the retinal...

The progressive deterioration of the visual function in patients on waiting lists for cataract surgery has a negative impact on their quality of life, especially in the elderly population. Patient waiting times for cataract surgeries in many healthcare settings have increased recently due to the prolonged stop or slowdown of elective cataract surgery as a result of coronavirus disease 19 (COVID-19). The aim of this review is to highlight the impact of such a "de-prioritization" of cataract surge...

Abstract Cystoid macular edema (CME) is a form of macular retina thickening that is characterized by the appearance of cystic fluid-filled intraretinal spaces. It has classically been diagnosed upon investigation after a decrease in visual acuity; however, improvements in imaging technology make it possible to non-invasively detect CME even prior to a clinically significant decrease in central vision. Risk factors for the development of CME include diabetic retinopathy, retinal vein occlusion, u...
