Summary and ConclusionsAlthough the CSC appears inactive at present, careful follow-up is advisable to detect recurrences and/or complications of CSC. The recent symptoms and changes in the SD OCT appear to be due to pigment migration, a finding often encountered in other disorders such as RP and Stargardts.Although our patient has large CD ratios and
The Preferential Hyperacuity Perimetry test (PHP)2,3 is intended to differentiate dry macula degeneration from early wet macula degeneration. It utilizes vernier acuity or hyperacuity which is 10-20 times more sensitive than standard Snellen visual acuity. The results below are normal in each eye. In addition, the FA failed to reveal any leakage and hence these
In contrast to the clean break in the PIL and RPE (left image), six months later it appears that some tissue is penetrating through the PIL (right image). Could this represent a CNVM or just pigment migration from the RPE towards the inner retinaSee movie presentation on page 1
Follow up Six months later the patient presented with a one week history of increased distortion on the Amsler grid OS to the left of the central fixation point. Clinical Findings VA OD 20/20 and OS 20/20 Fundus Exam: Areas of hyperpigmentation and depigmentation in the left macula that appear unchanged from several previous
The mfERGs demonstrate the responses in our 55 year old male patient. As shown in the image above, the left mfERG has a slightly reduced foveal peak when contrasted to the right.
Introduction to mfERG The typical stimulus for multifocal electroretinogram (mfERG) is shown in the left image above. Usually, 103 hexagons pattern reverse from white to black and black to white in a pseudo-random sequence. The resultant response from the retina is a topographically accurate ERG from 103 different locations. The total
In contrast to the normal appearing PIL OD, the OS clearly has a break which appears to also include a break in the underlying RPE. The PIL discontinuity is nasal to the fovea and appears normal under the foveal pit, which explains the 20/20 VA.
History/Chief Complaint 55 year old male with a history of central serous chorioretinopathy OS that dates back 4 years. Home Amsler reveals a subtle defect to the left of fixation OS. Clinical Findings BCVA: OD 20/20 and OS 20/20 Fundus Exam: - Cup/Disc Ratio: 0.75 H and 0.75 V OU. - Subtle pigmentary disturbance in
Complication central serous chorioretinopathy Left Eye Has this patient with a previously diagnosed central serous chorioretinopathy now developed CNV? Note the breaks in the photoreceptor integrity line (PIL) and in the RPE in sections 64 through 74. Topcon 3D 0CT 2 dimensional movie is composed of 128 horizontal sections beginning from
Central serous chorioretinopathy or choroidopathy (CSC) typically affects young to middle age males who have been described as having type A behavior. Although CSC is often self limited, some patients have persistent CSC, others have multiple bouts and some require treatment with laser or PDT. There is some evidence that patients with a history of
