OBJECTIVE To identify and correlate hypopigmented spots on fundoscopy with the leakage points on fluorescein angiography (FA) in patients with central serous chorioretinopathy (CSCR) to provide criteria for FA-free focal laser photocoagulation (FLP). METHODS Fifty consecutive patients of acute CSCR were evaluated between March and October 2019 confirming the inclusion and exclusion criteria. Colocalization of leakage points with discrete hypopigmented spots on clinical fundoscopy was evaluated using FA. Positive predictive value (PPV) was calculated to identify the status of association between these to formulate criteria for FA-free FLP of CSCR patients in future. RESULTS Out of the 50 eyes, 38 (76%) had a discrete hypopigmented spot on fundoscopy which coincided with the leakage point on FA. The PPV of finding a leakage point at the area of discrete hypopigmented spot is 95%. Colocalization with a pigment epithelial detachment was found in 25 (65.7%) of these 38 eyes. Retinal pigment epithelial irregularities were found associated in all of these 38 eyes. Subretinal homogenously hyperreflective material was found in 8 (21.05%) of 38 eyes. optical coherence tomography following FLP of leakage point in all cases showed complete resolution of CSCR in 47 (94%) eyes. CONCLUSIONS This study demonstrates that hypopigmented spots on clinical fundus examination in CSCR patients, when present, coincide with the leakage point of FA. This may aid to undergo FA-free FLP treatment in CSCR patients.

UI MeSH Term Description Entries
D007834 Lasers An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

D008028 Light Coagulation The coagulation of tissue by an intense beam of light, including laser (LASER COAGULATION). In the eye it is used in the treatment of retinal detachments, retinal holes, aneurysms, hemorrhages, and malignant and benign neoplasms.

D005451 Fluorescein Angiography Visualization of a vascular system after intravenous injection of a fluorescein solution. The images may be photographed or televised. It is used especially in studying the retinal and uveal vasculature.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D056833 Central Serous Chorioretinopathy A visual impairment characterized by the accumulation of fluid under the retina through a defect in the retinal pigment epithelium.

D041623 Tomography, Optical Coherence An imaging method using LASERS that is used for mapping subsurface structure. When a reflective site in the sample is at the same optical path length (coherence) as the reference mirror, the detector observes interference fringes.
