ABSTRACT
A 54-year-old gentleman presented with a history of poor vision in the right eye for three months and a prior forgotten trauma. The anterior segment was normal. He was diagnosed with subtotal bullous rhegmatogenous retinal detachment (RRD), but no apparent tear was observed. Vitrectomy commenced, and upon exploration, there was a posterior globe rupture with retinal and vitreous incarceration. The scleral wound was sutured with heavy liquid in situ. Orbital imaging post-surgery revealed the presence of an intraorbital foreign body. This is a peculiar presentation of posterior globe rupture, as it was unperceived by the patient, and the slit lamp examination conducted indicated no clinical evidence. Identifying posterior globe rupture remains a challenge that necessitates a high index of suspicion and appropriate management.
ABSTRACT
This case series discusses the presentation, etiologies, and management of retinal artery occlusions in three patients. The first case was diagnosed as right eye central retinal artery occlusion (CRAO) secondary to a hypercoagulable state as the patient had been newly diagnosed with chronic myeloid leukemia. The second case had right branch retinal artery occlusion (RAO) secondary to a thromboembolic event following a percutaneous transluminal coronary angioplasty procedure. The third case involved a right eye CRAO secondary to vasospastic syndrome. The first case had good visual recovery as the patient presented to us within four hours of the onset. In contrast, the second and third cases presented after seven to eight hours, resulting in poor visual recovery. Though several measures have been devised to reverse the occlusion, the final visual prognosis still depends on the degree of occlusion and the time of presentation, as late presentation is usually associated with irreversible visual loss. Detection of RAO may require a multidisciplinary team approach, and proper and timely management may reverse the ischemic state of the retina.
