FIELD: medicine.SUBSTANCE: invention aims at an individual selection of laser energy options in transcleral diode laser cyclophotocoagulation (TDLC) in the patients suffering absolute painful glaucoma. A ciliary body thickness is measured by ultrasonic biological microscopy (UBM). If the ciliary body thickness is 0.54 mm or less, 6 laser applicates are marked through a circular arc of 90° in an upper section and through a circular arc of 90° in a lower section at power 1.2 Wt, pulse energy 3.6 J. If the ciliary body thickness is more than 0.54 mm, 8 laser applicates are marked through a circular arc of 135° in the upper section and through a circular arc of 135° in the lower section at power 1.8 Wt, pulse energy 5.4 J. The exposure in both cases are contact transcleral with using a diode laser in a continuous mode at wavelength 810 nm and exposure time 3.0 sec. The applicates are marked 1-2 mm from the limb and equally spaced from each other.EFFECT: method provides a differential approach to selecting the laser energy options taking into account the condition of the ciliary body visualised by UBM which enables avoiding severe complications of TDLC, provides relieving pain syndrome, and reduces an initial intraocular tension.2 ex |
