Although ERG changes were identified at dosages between 50-1000 microg, the histology of all groups up to 1000 microg did not show any discernable abnormalities.
Purpose
To report a case of unilateral acute idiopathic maculopathy (UAIM) associated with yellow fever.
Observations
A 59-year-old man presented with acute blurring of his vision 30 days after symptoms of yellow fever virus infection. Findings resembling unilateral acute idiopathic maculopathy of the left eye were noted on ophthalmoscopy, fluorescein angiography and optical coherence tomography. The right eye exam was normal. He was managed conservatively and recovered complete visual function in 8 weeks.
Conclusions
We describe a case of unilateral acute idiopathic maculopathy disease in a patient infected by yellow fever virus confirmed with reverse transcriptase polymerase chain reaction (RT-PCR).
Background
The position of the intraocular lens (IOL) is a major factor that affects the final visual acuity after cataract surgery. However, no prospective study has compared the IOL positions associated with the sutureless intrascleral technique and the standard transscleral suturing technique. The current study compared the IOL positions in the two techniques using ultrasound biomicroscopy (UBM) in vivo.
Methods
Twenty-one eyes of 21 patients were included in this observational study conducted between February and May 2015. Eleven patients underwent the sutureless intrascleral technique, and 10 patients underwent transscleral fixation with suturing. Ophthalmologic examination and UBM were performed in all patients. Optic tilt was measured in relation to the iris plane. The haptic location was defined. Mann–Whitney test and multiple linear regression were used to analyze the vertical and horizontal gradients. Significant differences were considered when p ≤ 0.05.
Results
The most common indication for scleral fixation was a complication during phacoemulsification (81.81% in the sutureless group and 60% in the suture group). The mean vertical and horizontal tilts were, respectively, 0.24 ± 0.21 and 0.25 ± 0.19 mm in the sutureless group and 0.14 ± 0.17 and 0.23 ± 0.16 mm in the suture group. No significant differences were seen in the vertical tilt and horizontal tilt (p = 0.888 and p = 0.148, respectively) between the groups. Gender (p = 0.835), age (p = 0.888), follow-up time (p = 0.915), and surgical duration (p = 0.094) were not associated with optic tilt. Of the 22 haptics in the sutureless group, 21 (95.45%) were in the intrascleral tunnel; of the 20 haptics in the suture group, 13 (65%) were posterior to the ciliary body, four (20%) anterior to the ciliary body, and three (15%) in the ciliary sulcus.
Conclusion
This study showed that there are no significant differences in the IOL positions between the two techniques.
