The choroid in pregnancy

During pregnancy there can be different types of ocular changes including a decrease in corneal sensitivity, increase in central corneal thickness and curvature, decrease in intraocular pressure, central serous chorioretinopathy and ocular blood flow. Advances in ophthalmic imaging devices has...

Comparison of retinal pigment epithelium-choroid graft surgery and anti-VEGF therapy in patients with wet AMD

This was a randomised intervention study in wet AMD patients to investigate benefits of free RPE-choroid graft transplantation surgery versus (continuation of) anti-VEGF treatment. Twenty patients who met the inclusion criteria were subdivided into three subgroups, i.e. RPE tears involving...

Practical Handbook of OCT (Retina, Choroid, Glaucoma)

With the rapid development and expansion in the usage of optical coherence tomography (OCT) technology there is always demand for a new OCT publication on the bookshelves. The operation and acquisition skills required are more easily acquired than for the...

OCT choroidal signs for congenital retinal pigment epithelium hypertrophy

Congenital hypertrophy of the retinal pigment epithelium (CHRPE) on ocular coherence tomography (OCT) has the characteristic sign of RPE thickening and hyper reflectivity. However, the underlying choroid characteristics remain under researched. This retrospective study utilised data from an ophthalmic oncology...

Choroidal thickness in strabismus and amblyopia

The authors examined the effect of exotropia, esotropia, anisometropic amblyopia and hypermetropia on choroidal thickness in a prospective cross section study. The study included 100 patients and 20 controls with a mean age of 8.5±2.9 years; 61 female and 59...

Choroidal folds

Choroidal folds are undulations of the choroid, Bruch’s membrane and pigment epithelium, with wrinkling of the overlying retina. They may be idiopathic but can also be caused by a number of different conditions. Case report A 60-year-old male patient was...

Choroidal thickness in ocular sarcoidosis by OCT measurement

This is the first study to evaluate the choroidal thickness in patients with ocular sarcoidosis during the quiescent phase using enhanced depth imaging optical coherence tomography (EDI-OCT) and comparing with normal subjects. Ocular sarcoidosis may affect the choroidal circulation (occlusive...

Reduced blood flow and age-related macular degeneration

This was a prospective cross-sectional study assessing changes in blood flow velocity in patients with age-related macular degeneration (AMD) using a retinal function imager. Sixty eyes with wet AMD were compared to 53 control eyes and the average blood flow...

Aug/Sep 2015 Quiz 1

History A 60-year-old woman was referred to ophthalmology with a suspected left eye choroidal naevus. Visual acuity was unaffected in both eyes and she was asymptomatic. Ocular history and medical history were unremarkable. Questions Figure 1: Fundus photograph. 1. What...

Amblyopic choroidal thickness

The authors studied choroidal thickness in 38 paediatric cases (76 eyes) with unilateral amblyopia to evaluate the differences between amblyopic and fellow eyes, and compare them with 19 healthy control subjects (38 eyes). Anisometropic amblyopia was present in 17 cases...

A case of bilateral idiopathic sclerochoroidal calcification

Idiopathic sclerochoroidal calcification (ISC) is a rare, benign disorder of the choroid and sclera. We present a visually asymptomatic 83-year-old caucasian male with clinical findings bilaterally of ISC, and discuss the investigations required to confirm diagnosis and help prevent further...

Tumour deposits following choroidal melanoma treatment

The authors present the unique case of retinoinvasive melanoma following treatment of choroidal melanoma with brachytherapy. Uveal melanoma, the commonest intraocular malignancy in adults, presents as a pigmented mass in the choroid, ciliary body, or iris. A 79-year-old Caucasian male...
