Summary
Spectral domain optical coherence tomography (SD-OCT) can accurately measure choroidal thickness. Glaucoma patients show no macular choroidal thickness changes, but some glaucoma subsets exhibit thinner peripapillary choroids.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- The relationship between choroidal thickness and glaucoma remains unclear.
- Enhanced imaging techniques for spectral domain optical coherence tomography (SD-OCT) enable precise choroidal thickness measurements.
Purpose of the Study:
- To evaluate the capability of SD-OCT in documenting choroidal changes related to glaucoma.
- To review existing literature on choroidal thickness in glaucoma patients.
Main Methods:
- Utilized enhanced depth imaging with SD-OCT for reproducible choroidal thickness measurements.
- Analyzed nine published reports on macular choroidal thickness in glaucoma patients.
- Reviewed five studies investigating peripapillary choroidal thickness in glaucoma.
Main Results:
- SD-OCT with enhanced depth imaging provides reliable measurements of choroidal thickness.
- No significant differences in macular choroidal thickness were found between glaucoma patients and controls in most studies.
- Peripapillary choroidal thinning was reported in some glaucoma subsets, but findings were inconsistent across studies.
Conclusions:
- SD-OCT reliably measures choroidal thickness in macular and peripapillary regions.
- Macular choroidal thickness is not altered in glaucoma patients.
- A thinner peripapillary choroid may be associated with specific glaucoma subsets.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
