Various treatment modalities such as observation, pars plana vitrectomy (PPV), neodymium-doped yttrium aluminum garnet (Nd: YAG) laser posterior hyaloidotomy (LPH), and pneumatic displacement have been described for subhyaloid hemorrhage. LPH, though a noninvasive procedure, is associated with various complications., We report the development of FTMH along with the occurrence of subretinal bleed due to the photodisruptive effect of LPH.
A 23-year-old female with aplastic anemia developed sudden painless diminution of vision in her right eye (OD) since the last 10 days. Blood investigations showed pancytopenia (hemoglobin: 7.7 gm/dl, total white blood cell count: 1.2 × 109/L, and total platelet count: 2 × 109/L), and bone marrow aspiration showed hypocellularity without evidence of any malignant cells. The patient was admitted under the hematology department of our institution and had received multiple blood transfusions. The best-corrected visual acuity (BCVA) in OD and left eye (OS) was hand motion close to face (HMCF) and 6/12, respectively, with normal intraocular pressures. Fundus evaluation of OD revealed the presence of a 2DD boat-shaped area of subhyaloid hemorrhage (SHH) obscuring the fovea with multiple dot-blot and white-centered retinal hemorrhages, suggestive of anemic retinopathy [Figure 1]a.

Swept-source optical coherence tomography (SS-OCT) showed localized posterior hyaloid detachment with underlying hyper-reflective blood obscuring the fovea [Figure 1]b. Nd: YAG LPH was performed (6 mJ, two spots) using bloodcGoldman three mirror contact lens (Volk) at the inferior margin of premacular SHH, which resulted in the creation of an opening in the posterior hyaloid with immediate trickling of blood into the vitreous cavity.
At 3 weeks follow-up, BCVA improved to 6/60 and vitreous hemorrhage had resolved, but there was a FTMH associated with subretinal bleed [Figure 2].

| Discussion|| |
Both clinical examination and OCT can provide clues to differentiate SHH from sub-ILM bleed. Clinical clues such as the presence of surface striae and double ring favor sub-ILM bleed., Similarly, the presence of dual membranes or a persistent premacular cavity after membranotomy on OCT points toward sub-ILM bleed., Lack of any such clinical and OCT signs favored the diagnosis of SHH in our case.
FTMH occurred due to the direct impact of the photodisruptive laser at the fovea. This was followed by subretinal migration of the premacular hemorrhage through the FTMH. The presence of subretinal blood could potentially hamper the anatomic and functional success after FTMH surgery. Thus, it is important to highlight the occurrence of this rare complication following LPH.
This report highlights the fact that Nd: YAG LPH should be performed with utmost caution by using minimal possible energy and should be reserved for SHH of at least 3DD to avoid iatrogenic damage to the fovea.
