LPI in asymptomatic angle-closure suspects significantly reduced progression to angle closure or glaucoma over 5 years, but the overall progression rate was low.

Van Herick grading (VH) was studied against UBM for angle closure and plateau iris. VH ≤2 significantly correlated with UBM angle width and ciliary body configuration, suggesting its utility for screening these conditions.

Baskaran Mani, Yang Elizabeth, Trikha Sameer, Kumar Rajesh S, Wong Hon Tym, He Mingguang et al.

This study found over 80% of primary angle closure suspects had residual angle closure one year post-LPI. Larger baseline iris volume and higher IOP predict this, indicating LPI alone may not fully resolve angle closure in many.

Studying Asian eyes, higher iris crypt grading was linked to lower acute angle closure risk. Assessing iris crypts could help predict acute angle closure.

OCTA peripapillary vessel density showed good diagnostic ability for POAG and PACG, comparable to RNFL thickness. This suggests OCTA could be a valuable tool for glaucoma diagnosis.

Kumar Rajesh S, Anegondi Neha, Chandapura Rachana S, Sudhakaran Suria, Kadambi Sujatha V, Rao Harsha L et al.

OCTA vascular parameters effectively discriminate glaucoma severity, including preperimetric stages, often outperforming or matching standard visual field tests. This suggests OCTA is a useful diagnostic adjunct.

Prophylactic laser iridotomy in angle closure suspects showed a small, similar corneal endothelial cell density decrease in treated and untreated eyes over 3 years, suggesting no significant LPI-specific long-term harm.

This study found EyeCam and goniophotography similarly and highly effective compared to gonioscopy for detecting angle closure. These imaging tools offer reliable alternatives for clinical assessment.

This study found laser peripheral iridotomy (LPI) significantly opens the anterior chamber angle in angle-closure suspects by reducing iris curvature, increasing chamber area and volume.

This study characterized young Chinese myopes with glaucoma-like optic nerve changes, finding distinct refractive errors and optic disc tilt compared to established glaucoma, suggesting different clinical features but cautioning against definitive differential management.

Perera Shamira A, Ho Ching Lin, Aung Tin, Baskaran Mani, Ho Henrietta, Tun Tin A et al.

RTVue SDOCT's ability to image the anterior chamber angle was studied. It poorly visualized key angle structures compared to ASOCT and gonioscopy, limiting its clinical utility for comprehensive angle assessment.

Lavanya Raghavan, Baskaran Mani, Kumar Rajesh S, Wong Hon-Tym, Chew Paul T K, Foster Paul J et al.

Dilation with tropicamide and acetazolamide in Asian narrow-angle patients showed a low (0.64%) acute angle closure risk. Narrower angles predicted IOP elevation, suggesting safe dilation but highlighting specific risk factors.

Pang Claudine E, Lee Kelvin Y, Su Daniel H, Htoon Hla M, Ng Jamie Y, Kumar Rajesh S et al.

This study found Chinese PACG patients have similar central corneal thickness to POAG or normal eyes, suggesting CCT is not a distinguishing factor for PACG in this population.

Cheung Carol Y, Zheng Ce, Ho Ching-Lin, Tun Tin A, Kumar Rajesh S, Sayyad Fouad El et al.

This study developed new HD-OCT measures using the Schwalbe line to quantify anterior chamber angle width. These measures correlated well with existing methods, offering a reliable, independent tool for assessing angle closure risk.

Perera Shamira A, Baskaran Mani, Friedman David S, Tun Tin A, Htoon Hla M, Kumar Rajesh S et al.

EyeCam imaging showed good agreement with gonioscopy for detecting angle closure, but identified significantly more closed angles, suggesting it could be a valuable screening tool.

Perera Shamira A, Quek Desmond T, Baskaran Mani, Tun Tin A, Kumar Rajesh S, Friedman David S et al.

EyeCam effectively detected significant angle widening after LPI in angle-closure glaucoma, showing more open quadrants than gonioscopy. This suggests EyeCam can document LPI's success.

Combined bevacizumab and 5-FU significantly reduced scarring and improved bleb survival after glaucoma surgery in rabbits, suggesting a superior antifibrotic treatment for patients.

Baskaran Mani, Kumar Rajesh S, Govindasamy Chitra V, Htoon Hla Myint, Wong Ching-Yee, Perera Shamira A et al.

Angle closure glaucoma eyes showed higher diurnal IOP fluctuation than normal eyes, especially with more peripheral anterior synechiae and visual field loss, suggesting these factors impact disease progression.

This OOKP study found optic disc photography and visual fields are best for glaucoma monitoring, with oral medications and cyclophotocoagulation as treatment options.

GDx VCC scanning laser polarimetry showed moderate sensitivity but high specificity for early glaucoma in Indian patients. The Nerve Fiber Index score provides valuable diagnostic information, particularly with a high positive likelihood ratio.

This pilot study found the water drinking test's peak IOP strongly correlated with peak daytime IOP, suggesting it's a useful clinic measure for peak pressure in glaucoma patients.

Sakata Lisandro M, Lavanya Raghavan, Friedman David S, Aung Han T, Gao Hong, Kumar Rajesh S et al.

This study compared gonioscopy and AS-OCT for angle closure detection, finding AS-OCT identifies more closed angles, especially superiorly, suggesting it's more sensitive for detecting iridoangle contact.

This UBM study found plateau iris in one-third of primary angle closure suspect eyes after LPI, highlighting a significant anatomical variant requiring further research into its clinical management implications.
