A 60-year-old woman presented with complaints of diminished vision in the left eye for 8 months. She was hypertensive for 15 years on oral telmisartan. Best-corrected visual acuity in the right eye (OD) was 6/12, N6 and left eye (OS) was 6/60, N18. Anterior segment examination showed nuclear sclerosis grade 2 in both eyes and quiet anterior chamber. Intraocular pressure was 14mm Hg (OD) and 16mm Hg (OS). Fundus showed multiple retinal pigment epithelium detachments (PED) scattered throughout the posterior pole in both eyes [Figure 1]a and [Figure 1]b. Optic discs were small in size in both eyes. The left-eye optic disc showed temporal pallor. Optical coherence tomography confirmed the serous nature of pigment epithelial detachment with normal overlying neurosensory retina [Figure 1]c and [Figure 1]d. Fundus fluorescein angiography revealed hyperflourescent areas corresponding to the pooling of the dye under the PED and scattered multiple tiny hyperflourescent window defects in between the PEDs corresponding to granular retinal pigment epithelial (RPE) atrophic changes [Figure 2]a and [Figure 2]b. MRI brain showed microvascular ischemic changes with mild thinning of optic nerve.

| Discussion|| |
Isolated multiple PEDs is a rare presentation of unknown etiology. Widespread primary defect in adhesion between RPE and Bruch's membrane was assumed to be the cause for multiple PEDs. The vision in isolated PED eyes is normal unless complicated by coexisting pathologies such as pachychoroid CSR, hemorrhagic PED, and CNVM. In the present case, the left eye had poor vision secondary to non-arteritic ischemic optic neuropathy. It was a coincidental finding which might be secondary to small disc and underlying systemic risk factors.
The present condition should be differentiated from more common ARMD-associated drusenoid PED. which shows homogenous internal reflectivity on OCT. Other rare entities to be excluded are non-best multifocal vitelliform maculopathy, which shows deposits in the subretinal space on OCT and photoreceptor-RPE diastasis, which presents with serous retinal detachment. Although the macular picture in this case looks dramatic, ophthalmologists should remember that multiple serous PEDs alone cannot cause visual loss. Thus, a thorough search for alternate causes for visual loss should be done.
