Angle Closure Glaucoma: Treatment

Angle 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...

Area of Science:

Ophthalmology
Allergology
Immunology

Background:

Conventional allergy diagnostics often fail to pinpoint the specific triggers for vernal conjunctivitis.
Component-resolved diagnostics (CRD) using microarray allergen assays present a potential advancement in identifying causative allergens.

Purpose of the Study:

To assess the utility of CRD in detecting IgE-mediated hypersensitivity in tears and serum of vernal conjunctivitis patients.
To evaluate the efficacy of specific immunotherapy guided by CRD findings in managing vernal conjunctivitis.

Main Methods:

Evaluated 25 patients with vernal conjunctivitis.
Utilized CRD to identify specific allergens, including n Lol p 1, n Cyn d 1, and various grass pollen groups.
Administered specific immunotherapy based on CRD results.

Main Results:

CRD identified specific allergens in vernal conjunctivitis patients, with n Lol p 1, n Cyn d 1, and grass pollens being common triggers.
Conventional tests like skin prick tests and serum IgE were positive in only one case, highlighting CRD's sensitivity.
13 out of 25 patients showed clinical improvement after one year of CRD-guided immunotherapy.

Conclusions:

CRD is a more sensitive diagnostic tool for vernal conjunctivitis compared to traditional methods.
CRD-guided immunotherapy can lead to significant clinical improvements in patients suffering from vernal conjunctivitis.
