The current study showed that IVA led to significant retinal arteriolar vasoconstriction and choroidal thinning, which may cause reduced retinal blood flow.
Aim. To evaluate the peripapillary retinal nerve fiber layer (RNFL) changes in retinitis pigmentosa (RP) patients using spectral domain optic coherence tomography (Sd-OCT). Methods. We retrospectively examined medical records of forty-four eyes of twenty-two RP patients. The results were also compared with those of previously reported forty-four eyes of twenty-two normal subjects (controls). Records of average and four quadrants peripapillary RNFL thickness measurements using Sd-OCT were assessed. Results. In RP patients the mean RNFL thickness was 97.57 ± 3.21 μm. The RNFL in the superior, temporal, nasal, and inferior quadrants was 119.18 ± 4.47 μm, 84.68 ± 2.31 μm, 75.09 ± 3.34 μm, and 113.88 ± 4.25 μm, respectively. While the thinning of RNFL was predominantly observed in the inferior quadrant, the thickening was mostly noted in temporal quadrant. The differences between mean, superior, and nasal quadrant RNFL thicknesses were not statistically significant when compared with control group. The RP patients had thinner inferior quadrant and thicker temporal quadrant than control group (p < 0.05). Conclusion. Sd-OCT is highly sensitive and effective instrument to detect RNFL changes in RP patients. RNFL measurements can provide information about the progression of retinitis pigmentosa and may provide prognostic indices for future treatment modalities.
Re sults: The mean age was 25 (1-56) years. Twelve patients (80%) were males and 3 (20%) were female. Twelve (80%) eyes presented with lower canalicular laceration, 1 (6.7%) eye-with upper canalicular laceration, and 2 (13.3%) eyes had bicanalicular laceration. Five of injuries (33%) were due direct sharp objects and 10 of injuries (66%) occurred due to blunt trauma. Six of patients were operated under general anesthesia and 9 of patients were operated under local anesthesia. The mean time duration between canalicular injury and surgery was found to be 14 hours (4-39 hours). The mean duration of the tubes' residence time was 5.26 months (1-6 months). Patients were followed averagely 14 months (6-32 months) in the postoperative period. The open status of lavage was considered as anatomical success, and the absence of fluorescein dye pooling and epiphora was considered as functional success. Except for 1 patient with tube protrusion in the early postoperative first month, anatomical and functional success was achieved in 14 patients (93.3%) during the follow-up period. Conclusion: After traumatic canalicular lacerations, Monoka ® tube intubation is an easily applicable and effective method with low risk of damage. (Turk J Ophthalmol 2015; 45: 14-17)
