Ocular hypertension is the presence of elevated fluid pressure inside the eye (intraocular pressure), usually with no optic nerve damage or visual field loss. [ 1 ] [ 2 ] For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [ 3 ]
Parinaud's oculoglandular syndrome (POS) is a medical condition characterized by a specific set of symptoms affecting the eye and nearby lymph nodes.Named after the French ophthalmologist Henri Parinaud, it should not be confused with the neurological syndrome caused by a lesion in the midbrain which is also known as Parinaud's syndrome.
Ocular hypertension (IOP 30 - 70 mmHg) with open angle of anterior chamber and unilateral mild granulomatous anterior uveitis are hallmark signs of Posner–Schlossman syndrome. [2] On slit-lamp examination, conjunctival injections, epithelial corneal edema, [ 3 ] small to medium-sized fine keratitic precipitates, aqueous cells and flare may ...
Absolute glaucoma (H44.5) is the end stage of all types of glaucoma. The eye has no vision, absence of pupillary light reflex and pupillary response, and has a stony appearance. Severe pain is present in the eye. The treatment of absolute glaucoma is a destructive procedure like cyclocryoapplication, cyclophotocoagulation, or injection of 99% ...
Diabetes, for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
Central retinal artery occlusion: CRAO is characterized by painless, acute vision loss in one eye. [11] Central retinal vein occlusion: CRVO causes sudden, painless vision loss that can be mild to severe. [12] Branch retinal vein occlusion: sudden painless vision loss or visual field defect are the main symptom of BRVO. [13]
Glaucoma medication is divided into groups based on chemical structure and pharmacologic action. The goal of currently available glaucoma therapy is to preserve visual function by lowering intraocular pressure (IOP) in patients that have an increased intraocular pressure.
Because uveitic glaucoma is a progressive stage of anterior non infectious uveitis, uveitic glaucoma involves signs and symptoms of both glaucoma and uveitis.. Patients with acute non infectious anterior uveitis may experience the following symptoms: pain, blurry vision, headache, photophobia (discomfort or pain due to light exposure), or the observance of haloes around lights.
