Eligibility

Inclusion criteria

Inclusion criteria: 1. Age 50-60years patients diagnosed with angle closure spectrum [Primary angle closure suspects and primary angle closure patients] because age related lens thickening and forward movement progressively narrow the anterior chamber angle, hence increasing risk of angle closure. 2. Occludable angle [Shaffer Grade less than or equal to grade 2 in more than or equal to 2 quadrants. 3. Clear Cornea for imaging 4. Family history of Glaucoma with MYOC [Myocilin], OPTN [Optineurin] and CYP1B1.

Exclusion criteria

Exclusion criteria: 1. Secondary angle closure. 2. Previous intraocular surgery or laser 3. Corneal pathology affecting imaging

Design outcomes

Primary

MeasureTime frame
To compare Gonioscopy findings, AS-OCT parameters and Anterior Chamber depth by IOL Master 700 in inclusion criteria patients pre and post Nd:YAG Laser Peripheral Iridotomy in order to establish difference in anterior chamber angle.Timepoint: At baseline [pre-Laser] At week 1 [post-Laser] At week 4 [post-laser] At three months [post-laser]

Secondary

MeasureTime frame
To establish and confirm the correlation between AS-OCT and Gonioscopy findings pre and post laser peripheral iridotomy at week 1, week 4 and three months.Timepoint: At baseline [pre-Laser] At week 1 [post-Laser] At week 4 [post-laser] At three months [post-laser]
