Valsalva retinopathy is a prominent cause of premacular hemorrhage in young patients. We report the case of a young male patient with premacular hemorrhage due to Valsalva retinopathy who underwent Neodymium-doped Yttrium Aluminum Garnet (Nd: YAG) laser evacuation of the blood. Within 5 minutes, there was a significant clearance of the blood from the macular area. A week later we could demonstrate a vascular sign on fluorescein angiography. It is known that the source of blood in Valsalva retinopathy is the rupture of perifoveal capillaries. Based on the findings on fluorescein angiography we could postulate that the bleeding in our case could have been due to the rupture of a larger retinal venule.

Valsalva retinopathy was first reported by Duane in 1973. It typically presents as a sudden visual loss in an otherwise healthy individual, caused by a premacular haemorrhage secondary to a Valsalva manoeuvre. The most frequently reported causes of Valsalva manoeuvre include vomiting, coughing, straining and physical activities.,, A sudden increase in pressure in the intraocular veins, secondary to an increased intrathoracic pressure, causes spontaneous rupture of perifoveal capillaries. Predilection to the macula is explained by the absence of firm attachments of the internal limiting membrane (ILM) to the retina in this area.
| Case Report|| |
A male, 32 years of age, came to us with the sudden loss of vision in his left eye during a heavy bout of exercise. He did not have any systemic illness and any other significant ocular history. On examination, his best-corrected visual acuity (BCVA) in the right eye was 6/6 and counting fingers at 1 meter in the left eye. Anterior segment examination was normal in both eyes. The left eye showed a large premacular sub-ILM hemorrhage with no other detectable vascular abnormality [Figure 1]a. On spectral-domain optical coherence tomography (SDOCT), the blood was seen as a hyper-reflective dome-like elevation under the ILM and the hyaloid was seen as a separate membrane [Figure 1]b. We performed Nd: YAG LASER posterior hyaloidotomy and the puncture of the ILM which released the preretinal blood instantly in the vitreous and the macular area was almost clear from the blood within 5 minutes with immediate improvement in vision by 11 lines to 6/9 [Figure 1]c. With SDOCT the defect in the posterior hyaloid and the ILM created by the Nd: YAG LASER application was well delineated [Figure 1]d.

One week later his vision had improved further by one line to 6/6 and there was a complete evacuation of the sub ILM hemorrhage [Figure 1]e. A fluorescein angiogram revealed abnormal hyperfluorescence along the superotemporal arcade vessel [Figure 1]f and [Figure 1]g. SD-OCT image revealed the presence of a premacular empty cavity [Figure 1]h.
| Discussion|| |
Sub-ILM hemorrhages have been associated with various causes, the most common being Valsalva retinopathy and Terson's syndrome., The hemorrhage due to Valsalva usually resolves spontaneously and rarely causes visual loss in the absence of underlying ocular pathology such as proliferative diabetic retinopathy. However, spontaneous resolution of the hemorrhage may take up to 6 months. Prolonged contact of the retina with hemoglobin and its catabolites can possibly cause toxic retinal damage, which may be irreversible.
This case has three distinct features that we wish to highlight. First, the posterior hyaloid could be clearly seen on OCT and it indicated that the hemorrhage was sub-ILM which has been demonstrated previously in studies. However, these studies were based on time-domain OCT and the data on SDOCT is lacking. The location of blood whether sub ILM or subhyloid has been a matter of debate. This finding helps us in understanding the morphology of this condition.
Secondly, there was a significant evacuation of the blood within a short span of a few minutes from the premacular area with Nd: YAG LASER resulting in rapid improvement in vision. The fact that the intervention was performed within a few hours may have led to immediate response. Kroll and Busse had recommended this treatment within the first 3–4 days after the occurrence of hemorrhage. In such cases of premacular hemorrhages due to Valsalva retinopathy, early intervention can lead to rapid resolution of hemorrhage. Young economically active patients with higher visual requirements often expect a rapid recovery of vision. It is advisable to make judicial use of LASER energy as it is associated with complications including epiretinal membrane formation with ILM wrinkling, persistent non-clearing vitreous opacities, macular hole formation, and retinal detachment.,
Third, there was hyperfluorescence on fluorescein angiography along the border of the superior arcade vessel probably pointing towards possible healing of the ruptured vein. To the best of our knowledge, this is a new finding which would add to the source of blood in cases of Valsalva retinopathy.
| Conclusion|| |
It could possibly be concluded that if the amount of premacular blood is less we can presume that the source of blood could be due to rupture of smaller retinal capillaries and if the amount of blood collection is significant, involving the entire macular area then it could be due to rupture of a retinal venule.
