Iris Nevus

Iris nevus is common: 6% of patients with suspected iris melanoma have lesions other than melanoma, and 36% of them are nevi. Iris nevus turns into melanoma in approximately 8% of cases at a mean of 15 years. This case report provides the first description of an iris tumor examined with iris optical coherence tomography angiography (OCTA) compared to iris fluorescein angiography (IFA). A 60-year-old man with a diagnosis of iris nevus in the left eye was referred to our department for IFA and iris OCTA. The iris vasculature in IFA was visible only in the early phases, but not clearly. OCTA, however, gave visualization of the vascular network and very precisely defined the vessels of the whole lesion, except for the pupillary portion, which was masked by superficial pigment accumulations. IFA and iris OCTA can add information about the vascular architecture compared to slit-lamp biomicroscopy, ultrasound biomicroscopy, and anterior-segment OCT. However, IFA is time-consuming and invasive and can – very occasionally – cause serious adverse reactions. In contrast, OCTA defines the texture of the iris vasculature better. In conclusion, OCTA is a new method, easy to execute, needing no dye injection, and provides useful information on the vascular network of iris lesions. It could therefore be helpful in the diagnosis and follow-up of these lesions.

Significance: Perifoveal exudative vascular anomalous complex (PEVAC) is a unique clinical lesion. It manifests as isolated lesions and is easily misdiagnosed. Thus far, few PEVAC case reports have been published. PEVAC is typically inconsistent with other reported macular lesions.Purpose: To report our 24-month follow-up experience on the treatment of PEVAC with a micropulse laser (MPL).Case Report: A 56-year-old Chinese woman with no history of other diseases complained of decreased vision in her left eye that had persisted for more than 1 year. Comprehensive ophthalmic examinations were performed, including a vision test, slit lamp fundus exam, optical coherence tomography (OCT), optical coherence tomography angiography (OCT-A), fluorescein fundus angiography (FFA) and indocyanine green angiography (ICGA). Intravitreal injection of ranibizumab was ineffective, and bleeding, exudation and visual acuity were not improved. After two rounds of micropulse laser (MPL) treatment, the patient was followed up, and the prognosis was good.Conclusion: PEVAC is very rare, and early diagnosis is important, as the lesions readily cause irreversible damage. Our results indicate that an MPL can be used as an alternative treatment for PEVAC patients.

Purpose To present a case of nonexudative choroidal neovascularization secondary to angioid streaks in a patient with pseudoxanthoma elasticum. The lesion was monitored over an 8-month period with the use of optical coherence tomography angiography. Methods Case report. Results The neovascular tissue area increased by 0.160 mm2 over a period of 8 months without any sign of exudation seen on optical coherence tomography or fluorescein angiography. Conclusions To our knowledge, this is the first report of a nonexudative choroidal neovascularization secondary to angioid streaks. Given that once a patient with angioid streaks develops choroidal neovascularization in one eye there is a high risk of bilateral involvement within a short amount of time, optical coherence tomography angiography can prove a useful tool for monitoring such lesions over time.

Purpose: To demonstrate macular and optic disk vessel changes by optical coherence tomography angiography during and after a migraine attack with aura Methods: Case report Results: A 34-year-old healthy female patient was evaluated by optical coherence tomography angiography imaging during visual aura with phosphenes in the left visual field. Optical coherence tomography angiography imaging showed diffuse narrowing of the retinal vessels, decreased radial peripapillary capillary density, and decreased superficial and deep foveal vessel density in the right eye. These changes improved 3 hours after visual aura. The patient suffered from right eye pain and right-sided headache, which are typical for migraine, after the visual aura. Conclusion: These findings indicate that blood flow during migraine attack is reduced not only in the brain but also in the eye. Eye pain in migraine patients may be due to decreased blood flow in the eye. Restoring the vascular changes 3 hours after the visual aura suggests that vascular changes may be transient during a migraine attack.
