*Assessment and Management Protocol*
1. Clinical Presentation Overview
Age: 71 years
Comorbidity: Diabetes mellitus
Vision Loss: Sudden,
in OD), vision reduced to counting fingers at 1 meter
B-scan: Shows posterior vitreous detachment (PVD) and subhyaloid hemorrhage.
2. Pathophysiology
A subhyaloid hemorrhage occurs when blood collects between the posterior hyaloid face and the internal limiting membrane (ILM) of the retina. It often presents as a dense, boat-shaped or dome-shaped hemorrhage, typically associated with:
👉Diabetic retinopathy
👉Retinal vascular occlusions
👉Valsalva retinopathy
👉Terson syndrome (intraocular hemorrhage with intracranial bleed)
3. Diagnostic Workup
A. Clinical Examination
👉Visual acuity testing
👉Anterior segment examination
👉Fundus exam (dilated):
Shows a well-demarcated, boat-shaped pre-retinal hemorrhage
B. Imaging
1. B-scan ultrasonography
shows PVD and subhyaloid hemorrhage (hyperechoic fluid level under the posterior hyaloid membrane)
2. OCT (Optical Coherence Tomography)
to confirms location of hemorrhage between ILM and posterior hyaloid
Helpful to rule out associated macular traction or edema
3. Fundus Fluorescein Angiography (FFA)
Usually deferred until hemorrhage clears or in suspicion of neovascularization
Useful in diabetic patients to assess proliferative changes
4. Systemic workup
Blood sugar levels, HbA1c
Blood pressure
CBC and clotting profile (to rule out bleeding tendency)
4. Management Options
A. Conservative Management
Only for small hemorrhages or if vision is not severely affected:
👉Observation: Spontaneous resolution over weeks to months
👉Head elevation
👉Control systemic risk factors (diabetes, hypertension)
B. Active Intervention
Indicated in:
👉Dense hemorrhage involving the macula
👉Sudden, severe vision loss (as in this case)
👉Non-resolving hemorrhage (>2 weeks)
1. Nd:YAG Laser Hyaloidotomy / Membranotomy
For pre-macular (subhyaloid) hemorrhage:
Performed to create an opening in the ILM/posterior hyaloid, allowing blood to drain into the vitreous and clear faster
Quick visual recovery, but:
Requires clear view
Not suitable if PVD already exists or hemorrhage is too dense
2. Pars Plana Vitrectomy (PPV)
👉Preferred in this case due to:
👉Dense hemorrhage
👉Posterior vitreous detachment (increased risk of traction)
👉Diabetic background — possible proliferative diabetic retinopathy (PDR)
👉Removes hemorrhage, posterior hyaloid, and any neovascular membranes
👉Endolaser may be applied during surgery if PDR is confirmed
5. Postoperative and Long-Term Management
👉Post-surgical topical therapy: Antibiotic + steroid drops
👉Glycemic control: Essential to prevent recurrence
👉Follow-up fundus exams for diabetic retinopathy progression
Pan-retinal photocoagulation (PRP): If PDR is diagnosed intraoperatively or postoperatively
