ABSTRACT
A 60-year-old woman with a past medical history of branch retinal vein occlusion presented with decreased vision and metamorphopsia in her left eye. A fundus examination revealed a tortuous retinal vein with a few retinal hemorrhages in the inferotemporal quadrant. Optical coherence tomography revealed a partially separated posterior vitreous membrane pulling up the fovea. The patient refused surgical treatment so intravitreal triamcinolone acetonide (4 mg/0.1 mL) was administered. The patient reported resolution of symptoms in her left eye following this treatment, but her visual acuity did not show any improvement. Optical coherence tomography scanning revealed a complete detachment of the posterior hyaloid with release of the vitreomacular traction. In patients with vitreomacular traction and branch retinal vein occlusion, the combination of the possible vitreous liquefaction and mechanical increase of vitreous volume caused by an intravitreal injection with a degree of reduction in retinal thickness may play a role in the resolution of vitreomacular traction.
ABSTRACT
Cornea plana is a rare disease in which the cornea is flattened with a low refractive power. In addition to these features, hypermetropia, deep central corneal opacities, hazy corneal limbus, peripheral scleralization of the cornea and early arcus senilis can also be seen. Closed-angle glaucoma may occur as a result of shallow anterior chamber and narrow angle; however, open-angle glaucoma has also been reported in these patients. Measuring the real intraocular pressure (IOP) value of such eyes is difficult since tonometers are affected by corneal curvature. Therefore, the diagnosis of glaucoma may be delayed for a long time. In this case report we aimed to present a case of cornea plana with early open-angle glaucoma and to investigate which tonometer was appropriate for measuring the correct IOP value in such eyes.
