Valsalva retinopathy is characterized by a sudden visual loss due to preretinal hemorrhage, caused by a rapid increase in intraocular venous pressure. We hereby report a case of Valsalva retinopathy in a pregnant woman who was treated with Nd: YAG laser membranotomy.
| Case Report|| |
A 23-year-old pregnant female with 36 weeks of gestation presented with a sudden decrease in vision in her right eye for 2 days. She gave a history of severe vomiting before the onset of symptoms. Best-corrected visual acuity (BCVA) was counting fingers at 2 m in the right eye and 6/6 in the left eye. Fundus of the right eye showed premacular hemorrhage with a glistening white reflex and double-ring sign [Figure 1]a. Spectral Domain-Optical Coherence Tomography (SD-OCT) showed hemorrhage in sub-internal limiting membrane (ILM) space with a peg-shaped structure in the outer retina [Figure 1]b and [Figure 1]c. Blood pressure and random blood glucose were within normal limits. The patient was treated using a Q-switched Nd: YAG laser. A single burst of pulsed Nd: YAG laser was applied, starting with low energy (2 mJ) and then gradually increased until membranotomy became visible. The total energy used was 4 mJ. Nd: YAG laser membranotomy was done at the inferior aspect of premacular hemorrhage causing rapid dispersion of the hemorrhage into the vitreous cavity [Figure 2]a and [Figure 2]b. On 6 weeks follow-up after delivery, vision improved to 6/6 in the right eye. Fundus showed resolved premacular hemorrhage and little hemorrhage was noted in vitreous inferiorly [Figure 3]. SD-OCT showed a hyporeflective premacular cavity lined by the prominent hyperreflective membrane, presumably ILM. Another fainter reflecting layer, the posterior hyaloid, was visible separately and partly fused with the ILM in some areas [Figure 4]. Peg-shaped structure was noted in the outer retina corresponding to yellowish-white arcs at the outer margin of hemorrhage [Figure 4]b and [Figure 5].

| Discussion|| |
Valsalva retinopathy often occurs in healthy young adults and has been reported following coughing, weight lifting, vomiting, jumping, end-stage of labor, episodes of constipation, vomiting, and lifting in pregnant women. It is important to rule out systemic diseases such as diabetes, hypertension, sickle cell disease, anemia, coagulopathy, blood dyscrasias, and previous ocular vein occlusions. Valsalva maneuvers typically cause superficial retinal hemorrhages (sub-ILM and/or subhyaloid) with a predilection for the macula. If blood is localized in both spaces, it presents a “double-ring sign.” The outer and inner rings represent subhyaloid and sub-ILM bleed, respectively. Furthermore, subretinal, retinal, and vitreous hemorrhages have also been reported. It is difficult to distinguish between subhyaloid hemorrhage and sub-ILM hemorrhage clinically. The presence of glistening white reflex suggests sub -LM hemorrhage. SD-OCT can be used to differentiate between both. “Arcus retinalis” is a novel clinical sign described in a case of sub-ILM hemorrhage. A yellowish-white arc corresponds to a vertical peg-like structure in the outer retina on OCT as a result of localized traction on the retina by stretched ILM. Intervention should be done early in cases of sub-ILM hemorrhage to prevent toxic damage leading to irreversible visual loss. Nd: YAG laser treatment provides early visual rehabilitation in patients with Valsalva retinopathy irrespective of pregnancy status. It allows complete drainage of hemorrhage. However, there is a risk of photomechanical retinal injury and iatrogenic macular hole following laser. Vitrectomy surgery has also been done with success.
