Optic canal measurements in children

The authors aimed to determine the normal range of optic canal diameters in a Turkish pediatric population. They evaluated 200 CT examinations: 102 females, 98 males with mean age of 86.42 ±65.39 months (range 1-211). There was no significant difference...

Newer generation IOL platforms designed for high-quality visual performance after cataract surgery

Expanding intraocular lens (IOL) capabilities provide broadening options, ranging from next-generation monofocal IOLs for basic cataract surgery, to specialised premium IOLs for lens-based presbyopia correction and astigmatism correction at the time of cataract surgery. Rod McNeil considers several newer alternative...

OCTA optic disc measurement differences between glaucoma and pituitary macroadenoma

This prospective case-control study aimed to assess the potential of optical coherence tomography (OCT) and OCT angiography (OCTA) in distinguishing between glaucoma and pituitary macroadenoma based on optic disc appearance. Thirty-one patients (23 with glaucoma, eight with pituitary macroadenoma) were...

Early detection of progression of glaucoma, and escalating treatment is vital to maintain vision in patients. In this paper from the Early Manifest Glaucoma Trial (EMGT) group they compared the earliest detection of progression in visual fields and monoscopic optic...

Unique case of steroid-induced intraocular pressure spike causing NAION

The literature describes previous cases of nonarteritic anterior ischaemic optic neuropathy (NAION) following rapid rises in intraocular pressure (IOP) leading to reduced optic nerve head perfusion and disruption. This is commonly following ophthalmic procedures, acute glaucoma or steroid eye drops....
