RESUMO
We report a case of acute methanol toxicity with unique optical coherence tomography findings. A 56-year-old man was referred to our ophthalmology clinic with a history of handmade vodka consumption and vision loss. On ophthalmologic examination, his vision was 20/100 in his right eye and 20/200 in his left eye. Bilateral mild optic disk hyperemia was detected on fundus examination. Because of the severity of systemic symptoms in such cases, it is very difficult to include optical coherence tomography in the ophthalmologic examination. However, we managed to perform optical coherence tomography and recorded shallow subretinal fluid and a prominent middle limiting membrane sign as acute retinal structural changes in the patient. The patient was treated with hemodialysis, intravenous ethanol, and sodium bicarbonate. On the fourth day of treatment, visual acuity improved to 20/20 in both eyes. In addition, the prominent middle limiting membrane sign and subretinal fluid disappeared. In this unusual case, retinal pigment epithelium damage and retinal ischemia may have contributed to the prominent middle limiting membrane and subretinal fluid, which are novel optical coherence tomography findings of methanol toxicity.

OBJECTIVE: To evaluate the effects of solifenacin, darifenacin, and propiverine on nasal-, subfoveal-, temporal choroidal thicknesses (NCT, SFCT, TCT), intraocular pressure (IOP) and pupil diameter (PD). MATERIALS AND METHODS: Patients with overactive bladder (OAB) diagnosed according to The International Continence Society were administered with solifenacin, darifenacin or propiverine on a daily basis between November 2017 and May 2018. NCT, SFCT, TCT, IOP, and PD of these patients were measured and compared as initial, fourth and twelfth weeks. RESULTS: A total of 165 patients (330 eyes) with OAB were evaluated. Solifenacin (n=140) signifi cantly reduced IOP from 17.30±2.72 mmHg to 16.67±2.56 mmHg (p=0.006) and 16.57±2.41 mmHg (p=0.002), at the fourth and twelfth weeks, respectively. Darifenacin (n=110) signifi cantly reduced NCT from 258.70±23.96 µm to 257.51±22.66 µm (p=0.002) and 255.36±19.69 µm (p=0.038), at the fourth and twelfth weeks, respectively. Propiverine (n=80) signifi cantly increased PD from 4.04±0.48 mm to 4.08±0.44 mm (p=0.009) and 4.09±0.45 mm (p=0.001), at the fourth and twelfth weeks, respectively. CONCLUSION: These findings can help to decide appropriate anticholinergic drug choice in OAB patients. We finally suggest further well-designed randomized prospective studies with a larger population to evaluate the anticholinergic-related complications in eyes.
