Use of trypan blue as an aqueous tracer dye to investigate hypotony where cyclodialysis cleft is suspected.

Importance: A new method to help diagnose suspected cyclodialysis clefts.

Background: To study the use of trypan blue stained aqueous flow patterns in diagnosing causes of hypotony where cyclodialysis clefts were suspected.

Design: A case series in a tertiary care centre.

Use of trypan blue to assess lymphatic function following trabeculectomy.

Importance: To illustrate the importance of lymphatic drainage in assessing trabeculectomy bleb function using intracameral trypan blue.

Background: To study the lymphatic drainage of trabeculectomy blebs using trypan blue, correlate with bleb function and classify them accordingly.

Design: Prospective cross-sectional study in a tertiary care centre.
