PURPOSE: To assess the usefulness of two spectral domain optical coherence tomography (SD-OCT) instruments (Cirrus(R), Spectralis(R)) for evaluating optic nerve head and peripapillary structures. METHODS: Images of optic nerve complex were obtained from 136 eyes of 136 patients using enhanced depth imaging technique of 2 SD-OCT instruments. Optic nerve head and peripapillary structures were investigated for their visibility and morphological features in total eyes and glaucomatous eyes. Effect factors for laminar thickness measurement were evaluated and the reproducibility of the lamina cribrosa thickness measured by the 2 OCT instruments was analyzed. RESULTS: Lamina cribrosa thickness was better identified using Spectralis(R) OCT in total and glaucomatous eyes. Short posterior ciliary artery (in total eyes) and peripapillary choroid (in total and glaucomatous eyes) were also better identified using Spectralis(R) OCT (p < 0.001). A cup-disc ratio < or = 0.6 was the significant effect factor for laminar thickness measurement (p < 0.05). Interobserver reproducibility was excellent using both OCT instruments. Intraobserver reproducibility was excellent using Spectralis(R) OCT and moderate using Cirrus(R) OCT. CONCLUSIONS: Spectralis(R) OCT was better for visualizing optic nerve head and peripapillary structures and showed better reproducibility than Cirrus(R) OCT. Thus, the Spectralis(R) may be helpful for detecting and understanding features of the optic nerve complex.

While diverticulosis of the colon is a relatively common disease, a solitary giant colonic diverticulum is rare. Although there exist some theories about the formation of the giant colonic diverticulum, none is really conclusive. The preoperative diagnosis of giant colonic diverticulum is made radiographically with findings of a large, smoothly marginated, round homogeneous radiolucency in the abdomen that is in close apposition to the colon on barium enema examination. Early surgical treatment is necessary since the complication rate is high. One case of giant colonic diverticulum is presented, the clinical, radiologic and pathologic findings are discussed, and the etiology and differential diagnosis, reviewe.

PURPOSE: To compare the exodrift between unilateral lateral rectus (ULR) recession and observation groups in moderate angle intermittent exotropia (IXT). METHODS: A retrospective study was performed in 769 patients who were diagnosed with IXT from 2005 to 2015. Seventy-six patients were enrolled in this study that presented with IXT of 20 to 25 prism diopters (PD) on their first visit and were observed for more than 6 months without or after operation. The observation group (group 1) was composed of 29 patients who had regular examination without operation. The surgery group (group 2) was composed of 47 patients with ULR recession that were observed for deviation changes since surgery. RESULTS: The mean age was 71.8 ± 22.0 months at first visit in group 1 and 91.1 ± 18.9 months before surgery in group 2 (p < 0.01). The distant exodeviation was 22.9 ± 2.5 PD at first visit in group 1 and 22.9 ± 2.4 PD before surgery in group 2 (p = 0.89). During follow-up, mean exodrift was 0.6 ± 9.0 PD in group 1 and 10.0 ± 7.4 PD in group 2 (p < 0.01). Exodrift up to postoperative 6 months in group 2 was 3.2 ± 4.0 PD and exodrift from postoperative 6 months to 2 years in group 2 was 7.1 ± 6.9 PD. More exodrift was noticed after post-operative 6 months (p = 0.04). CONCLUSIONS: Comparing the exodrift between the groups in moderate angle IXT, patients in the observation group showed less exodrift. Patients who had a ULR recession presented more exodrift after postoperative 6 months. Even though they were orthotropic at postoperative 6 months when the operation was thought to be stabilized, an increase in exodrift after postoperative 6 months could not be excluded.

PURPOSE: To investigate the changes in choroidal thickness in diabetic retinopathy patients after panretinal photocoagulation (PRP). METHODS: This retrospective study included 42 eyes of treatment-naive, severe non-proliferative diabetic retinopathy or proliferative diabetic retinopathy patients undergoing 3-session PRP. At baseline and 1 and 2 months after completion of the PRP treatments, subfoveal choroidal thickness (SFCT) was measured using enhanced depth imaging optical coherence tomography. RESULTS: The mean SFCT at baseline was 261.52 +/- 77.98 microm, changing to 249.14 +/- 72.23 microm and 242.95 +/- 70.28 microm at 1 and 2 months, respectively (p < 0.05). The mean central macular thickness (CMT) was increased (>10%) in 9 eyes (21.43%) at 1 month and 8 eyes (19.05%) at 2 months after PRP. The mean SFCT showed no significant difference between increased mean CMT (238.22 +/- 57.59 microm and 240.00 +/- 67.71 microm at 1 and 2 months, respectively) and stable mean CMT groups (252.12 +/- 76.24 microm and 243.65 +/- 71.84 microm at 1 and 2 months, respectively; p > 0.05). CONCLUSIONS: Choroidal thickness decreased after PRP. There was no significant relationship between change in SFCT and CMT after PRP.
