Retinal detachment following focal laser to ruptured retinal artery macro aneurysm.

A 53-year-old lady presented with inferior retinal detachment (RD) following focal laser for retinal artery macroaneurysm (RAM). She underwent focal laser with intravitreal gas injection elsewhere; however, no retinal break was localized on the examination. The patient was taken up for vitreoretinal surgery. Intraoperatively, it was noted that the retinal detachment was not extending to the retinal periphery and primary retinal break was not localized even during the scleral depression. Under high magnification, using a macular lens, a slit-like retinal break was noted at the area of previous focal laser. Focal laser for RAM probably caused this retinal break leading to RD. The clinician needs to be aware that during focal laser of ruptured RAM, haemorrhage may preclude the view of retinal structures leading to inadvertent use of excessive laser energy. Retinal breaks may form at the site of laser due to coagulative necrosis. During surgical management of RD in such cases, the area of focal laser should be thoroughly examined under high magnification to avoid missed breaks.

Ruptured retinal macroaneurysm complicated by a retro hyaloidal hematoma: about a case and review of the literature.

A 45 years old patient consulted for a sudden decrease in visual acuity in the right eye. Ophthalmological examination gave visual acuity limited to luminous perceptions with a calm anterior segment, a transparent lens and at the fundus examination a dense, massive, two-level intra-retinal and retro hyaloidal pigeon nest hemorrhage with a fusiform whitish lesion on the path of the upper temporal artery. The suspected diagnosis was a complicated ruptured retinal macroaneurysm with massive retinal and retro hyaloidal hemorrhage. Fluorescein angiography confirmed the diagnosis. Our course of action was an emergency programmed evacuation vitrectomy with gas tamponade. The evolution was marked by a clear improvement in visual acuity. The rupture of retinal macroaneurysm is a frequent and serious accident. The complications of this rupture can threat the vision. Care is still being discussed. Randomized studies on large series are necessary to decide on the best therapy.

Retinal arterial macroaneurysm associated with macular pucker.

PURPOSE: To describe a case of retinal arterial macroaneurysm associated with macular pucker with good response to subthreshold laser treatment. PRESENTATION: Two-year follow-up of a patient with decreased vision in one eye for the past 6 months. Baseline best-corrected visual acuity was 20/40 in the affected eye. Multiple retinal arterial macroaneurysms were diagnosed on biomicroscopy fundus examination, with the presence of subretinal fluid and hard exudates on macula. Multimodal imaging including optical coherence tomography and fluorescein angiography confirmed the diagnosis and presence of macular pucker, which complicated the treatment choice. The largest retinal arterial macroaneurysm was treated 2 days after the diagnosis by means of subthreshold micropulse laser using an infrared diode laser with 1400 mW power, 200 ms exposure and 10% duty cycle. RESULTS: Five months after the treatment, despite absorption of subretinal fluid, there were increased hard exudates at the posterior pole and best-corrected visual acuity was unchanged. Progressively, the exudates were absorbed and vision improved. Eighteen months after the treatment, best-corrected visual acuity was 20/25. Hard exudates were almost completely reabsorbed, with no evidence of fluid. Macular pucker was unchanged, with no retinal traction or complications related to conventional laser treatment. CONCLUSION: Subthreshold laser treatment could be the treatment of choice in complicated cases of retinal arterial macroaneurysm with macular pucker, as it is able to modify the vessel permeability, without any thermal negative effect.

Intraoperative Optical Coherence Tomography Demonstrating Macular Hole Associated With Ruptured Retinal Arterial Macroaneurysm.

A 67-year-old female presented with vitreous hemorrhage and sub-internal limited membrane (ILM) hemorrhage in her right eye associated with ruptured retinal arterial macroaneurysm. During pars plana vitrectomy, intraoperative optical coherence tomography aided in the diagnosis of a small macular hole previously obscured by the sub-ILM hemorrhage. Nonexpansile gas was placed followed by postoperative prone positioning, and the hole closed successfully. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:e125-e127.].
