The significant difference was observed among normal lens position and slight and other subluxations of the lens detected by 25 MHz UBM except the minimum distance between lens equator and ciliary process
of the subluxated lens (Table 3).
When done as an outpatient procedure, TALC of the ciliary processes
also shows promise as a convenient, low-risk, and useful alternative procedure in selected aphakic glaucoma cases that are poorly controlled by medical or surgical measures.
found that the distal and intermediate parts of the ciliary processes
presented necrotic changes of the stroma and epithelium, ranging from oedema to vascular congestion; conversely, the basal parts of the ciliary processes
and the rest of the ciliary body appeared normal [19, 92].
In contrast to anterior segment optical coherence tomography and Scheimpflug imaging, which do not penetrate past the iris pigment epithelium to a large degree, UBM can show the exact configuration and position of the iris, ciliary body, and ciliary processes
even in the presence of opaque media.
Aqueous humour is derived from the blood plasma of the capillaries within the ciliary processes
of the ciliary body.
The authors stated that TALC may be a safe and effective alternative method for reducing IOP in eyes that have visible ciliary processes
and do not respond to conventional treatments.
Six percent of the eyes (3/46) had four haptics located in the ciliary sulcus (Figure 9(a)), 70% of the eyes (32/46) had four haptics located in the ciliary processes
(Figure 9(b)), and 24% eyes (11/46) had haptics located either in the ciliary processes
or in the ciliary sulcus.
Laser treatments include neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser hyaloidotomy/ capsulotomy, argon laser treatment of ciliary processes
, or transscleral cyclophotocoagulation [4-7].
