Autosomal dominant juvenile open-angle glaucoma was mapped by linkage analysis to chromosome 1 in the region q21-q31 (official locus name, GLC1A)by Sheffield et al.4 Subsequent linkage and haplotype analysis of additional families with GLC1A has restricted this region to that bracketed by D1S196 and D1S218 markers.5 Although Seghatoleslami et al6 have excluded the association of chronic open

In open-angle glaucoma the drainage area in the eye is open but not working properly and pressure slowly builds up, causing gradual loss of peripheral vision. 2. Normal tension glaucoma This is where the pressure inside the eye is within the normal range but nerve damage still occurs in spite of this. This accounts for about 25% of glaucoma cases and is more common in Asian races and people
2.2.1 Trabeculotomy ab interno for open angle glaucoma aims to reduce IOP by removing a portion of the trabecular meshwork to improve drainage of aqueous humour. It avoids the creation of a subconjunctival bleb associated with traditional trabeculectomy. 2.2.2 With the patient under local (intracameral) anaesthesia, a scleral incision is made and viscoelastic is inserted into the anterior

Glaucoma is a heterogenous group of optic nerve diseases that can be divided into congenital, juvenile onset and adult onset categories.

In patients younger than 35 years old, open-angle glaucoma is often diagnosed as juvenile open-angle glaucoma (JOAG) .
