Relapse of the ciliary body with glare treated with a neodymium-doped yttrium aluminum garnet laser

Abstract

consistent with the change evident on objective OQAS To the Editor:Wehave reported that a patient with cysts of the ciliary body and glare was treated with a neodymiumexamination. However, as we treated multiple cysts, the doped yttrium aluminum garnet laser. The patient complained of recurrent glare in the left eye 3 years after initial treatment. The anterior segments of both eyes were unremarkable; iris holes created by the neodymiumdoped yttrium aluminum garnet (Nd:YAG) laser were evident. An iris root bombe was apparent at 8 o’clock in the left eye. Right eye refraction was 1.0, –3.0/–1.75 170 → 0 (logMAR) and left eye refraction 1.0, –4.75/–0.5 45 → 0 (logMAR). The intraocular pressure of both eyes was 16 mmHg. Optical Quality Analysis System (OQAS; Visiometrics, Terrassa, Spain) examination revealed that the objective visual quality of the left eye had declined once more. The objective scattering index (OSI), modulation transfer function (MTF) cutoff, and Strehl ratio were 0.5, 40.975, and 0.183 for the right eye and 2.6, 18.603, and 0.128 for the left eye [Figure 1A]. As multiple, nonpigmented, ciliary body cysts were evident in both eyes, we performed immediate YAG laser cystectomy through the iris incision at 8 o’clock in the left eye. The patient reported that the glare resolved immediately. On OQAS examination, the left eye synchrony had improved, and the OSI, MTF cutoff, and Strehl ratio were 1.5, 23.411, and 0.139 [Figure 1B]. One week later, the left-eye glare had disappeared completely. The left eye refraction was 1.0, –4.75/–0.5 45 → 0 (logMAR) and the intraocular pressure 18 mmHg. The OSI, MTF cutoff and Strehl ratios of the left eye were 0.6, 44.539, and 0.30, respectively [Figure 1C]. A new iris hole was evident at the 8:30 o’clock position [Figure 1D].
