“…It might be helpful especially for a less experienced surgeon. A unique feature of this procedure is that Cloquet's canal and the precortical pocket are visualized vividly in many cases [23,24]. In proliferative diabetic retinopathy, a fibrous tissue sometimes proliferates upwards, forming a tube-like structure from an optic disc.…”

“…Triamcinolone acetonide-assisted visualization of the vitreous has been reported as a helpful tool for surgeons performing procedures such as internal limiting membrane peeling or posterior vitreous separation (9)(10)(11)(12)(13)(14)(15)(16) . However, this is the first study to describe the use of triamcinolone-guided 3D vitrectomy in the treatment of diabetic vitreomacular traction.…”

Purpose:To evaluate the efficacy of triamcinolone as an aid in vitreous visualization during 3D-vitrectomy for the treatment of diabetic vitreomacular traction. Methods: Prospective interventional study in patients with symptomatic vitreomacular traction. Pre-and postoperative assessments included visual acuity, retinography, intraocular pressure and optical coherence tomography. All patients were operated by the same surgeon (OOMJ). Triamcinolone was used as a visual enhancer during surgery. The parameters of the vitreophage (Accurus 800CS, Alcon) were set to the 3D-system (dual dynamic drive), contact lenses (plain and wide angle) being used for visualization. Peripheral 360º vitreous circumcision at high cut rate was performed, carefully releasing the vitreomacular adhesion at the posterior pole by means of an appropriate pic or vitreoretinal forceps. Results: The sample consisted of five consecutive patients (five eyes), three female and two male, with symptomatic vitreomacular traction. Their age ranged from 54 to 71 years (mean 62.6 ± 6.3 years). During the surgical procedure, the areas with vitreomacular traction were properly visualized and identified after the application of triamcinolone. No complications were recorded during or after surgery. There was a statistically significant improvement in visual acuity after the surgical procedure (p=0.0313). Conclusion: Triamcinolone facilitates the surgical treatment of vitreomacular traction by improving visibility of both the vitreous humor and the vitreous-retina interface. Triamcinolone-assisted 3D vitrectomy proved to be an effective procedure in these cases. ABSTRACT INTRODUCTION

“…CC is measured from 1 mm to 2 mm in width and from 4 mm to 5 mm in length and it reaches from the optic disc to the retrolental space. CC disappears in the intrauterine developmental period of the eye, nevertheless it can persist in healthy mature eyes and commonly it cannot be clearly visualized with ophthalmoscopic examination [3]. In this report, we presented a case with low visual acuity due to persistent CC.…”

The Cloquet's canal (CC) is the remnant of the primary vitreous and it disappears in the intrauterine developmental period of an eye. Rarely it can persist in mature eyes and cause low visual acuity. We detected a persistent CC and low visual acuity in a 36 year-old patient. Fundus fl uorescein angiography and optical coherence tomography examinations were completely normal in our case and low visual acuity was directly associated with opacifi cation of the fi brovascular persistent CC tissue. Persistent CC can cause low visual acuity due to directly media opacity effect of fi brovascular tissue without any complication.
