A 17-year-old male with acute myeloid leukemia (AML), presented with diminution of vision OS for 6 months. The best-corrected visual acuity was 6/9 OD and 4/60 OS. Anterior segment OU was normal. Fundus revealed pale disc OD with multiple areas of well-circumscribed pigmentary changes [Figure 1]a and vitreous hemorrhage OS. The patient underwent OS 25-G vitrectomy after informed consent. After clearing hemorrhage and induction of posterior vitreous detachment (PVD), multiple pigmented areas similar to OD including one at macula were noted [Figure 1]b. Intraoperative optical coherence tomography (I-OCT) revealed them to be areas of regressed sub-internal limiting membrane (ILM) hemorrhage with premacular cavity [Figure 2]a and [Figure 2]b Besides, the underlying macula was found to be thinned out. Brilliant blue G-assisted ILM peeling was done at the macula and routine postoperative treatment was given. At 1-month postoperatively, visual acuity improved to 6/60. Fundus revealed multiple such patches in the periphery and OCT revealed macular atrophy [Figure 3]a and [Figure 3]b.

| Discussion|| |
PIONEER and DISCOVER studies have demonstrated the usefulness of I-OCT in intraoperative surgical decision making in a significant number of posterior and anterior segment surgeries., Though altered blood visible along inferior margins [Figure 2] pointed towards the possibility of sub-ILM hemorrhage, the shape as well as the color of the lesions was not characteristic of premacular cavity and resembled retinal pigment epithelium alterations. I-OCT helped us to confirm the presence of premacular cavity, which led us to the diagnosis of resolved sub-ILM hemorrhage., Since the vitreous had already been removed, the possibility of subhyaloid hemorrhage was not considered. Intraoperative diagnosis of atrophic macula helped us to explain prognosis to the patient. I-OCT may, therefore, act as a useful tool for documentation, an integral part of modern medicine.
Intraoperative feedback from I-OCT helped us in the characterization of resolved sub-ILM hemorrhage, guiding surgical decision to peel ILM and in explaining the expected prognosis.
