“…1 Although commonly associated with vascular risk factors, more recent case reports have shown PAMM to occur after a variety of ocular surgeries, including pterygium removal, cataract surgery, and vitrectomy. 7,8,10,11 Hooshmand et al 8 published a letter to the editor describing a case of PAMM after vitrectomy for vitreous hemorrhage in the setting of previous retinal tears. The patient in that case had medical history significant for hypertension, mild mitral valve prolapse, and stable glaucoma.…”

Purpose: To describe a patient with newly developed paracentral acute middle maculopathy after uncomplicated epiretinal membrane removal.Methods: Retrospective chart review.Results: A 74-year-old white man underwent uncomplicated vitrectomy and epiretinal membrane removal in his left eye. One week later, the patient complained of a small paracentral visual field deficit and decreased visual acuity. Spectral domain optical coherence tomography revealed a characteristic hyperreflective band-like lesion at the level of the inner nuclear layer, consistent with paracentral acute middle maculopathy. The patient was closely followed and endorsed subjective improvement of his paracentral visual deficit at 3 months postoperatively.Conclusion: Paracentral acute middle maculopathy, although rare, may be encountered after epiretinal membrane removal.

“…Cerebrovascular illness, periocular anaesthesia that raises orbital pressure and narrows the central retinal artery's flow, and elevated intraocular pressure in early postoperative phases are also suggested as contributory causes 31 . A 70-year-old Caucasian woman with a history of coronary artery disease, multiple prior strokes, hypertension and peripheral vascular disease was the subject of a case study published in 2020 by Kelly H et al 32 .…”

Paracentral acute middle maculopathy (PAMM) is identified by the occurrence of an inner nuclear layer (INL) hyperreflective band on optical coherence tomography (OCT), which was subsequently accompanied by INL atrophy. A multitude of systemic diseases and vasculopathy risk factors have been linked to PAMM. PAMM, which has been associated with infection with Coronavirus disease 2019(COVID 19), may indicate post-infectious complications. By influencing vascular endothelial cells, COVID-19 infection can induce an inflammatory and procoagulatory state, resulting in vascular thromboembolic complications, although the precise mechanisms underlying these complications remain unknown. Thus, the present review explores and discusses about paracentral acute middle maculopathy, its diagnosis and treatment and adds a note on its implications after the outbreak of COVID 19.

Two recent cases of central retinal artery occlusion under otherwise uncomplicated sub-Tenon’s block that resulted in significant visual loss after cataract surgery prompted us to undertake a literature review of such cases. We identified 97 cases of retinal artery occlusion after ophthalmic surgery under regional anaesthesia that had no immediate signs of block-related complications. These occurred after various intraocular (87%) and extraocular (13%) operations, across a wide range of ages (19–89 years) on patients with (59%) or without (39%) known risk factors. The anaesthetic techniques included 40 retrobulbar blocks, 36 peribulbar blocks, 19 sub-Tenon’s blocks, one topical anaesthetic and one unspecified local anaesthetic. Different strengths of lidocaine, bupivacaine, mepivacaine and ropivacaine, either alone or in various combinations, were used. The details of the anaesthetic techniques were often incomplete in the reports, which made comparison and analysis difficult. Only nine cases had their cause (optic nerve sheath injury) identified, while the mechanism of injury was unclear in the remaining patients. Various mechanisms were postulated; however, the cause was likely to be multifactorial due to patient, surgical and anaesthetic risk factors, especially in those with compromised retinal circulation. As there were no definite risk factors identified, no specific recommendations could be made to avoid this devastating outcome. We have provided rationales for some general considerations, which may reduce this risk, and propose anaesthetic options for ophthalmic surgery on the fellow eye if required, based both on our literature review and our personal experience.
