ABSTRACT
PURPOSE:
We report a case of asymptomatic unexplained visual field loss diagnosed as early retinitis pigmentosa (RP) without pigmentation. CASESUMMARY:
A 33-year-old woman was referred to us with a constricted visual field (C24-2) before laser-assisted in-situ keratomileusis surgery. The visual field test (C30-2) revealed significantly decreased sensitivity between 15 to 25 degrees in both eyes. Close fundus examination revealed a subtle greyish retinal atrophic lesion along the vascular arcade and fluorescein angiography revealed a window defect in accordance with a retinal atrophic lesion in both eyes. Optical coherence tomography showed decreased retinal thickness around the macula. Electroretinogram revealed decreased b waves in rod response. Based on these findings, we diagnosed the patient with early RP without pigmentation.CONCLUSIONS:
The possibility of early RP without pigmentation presenting as slight atrophy around the macula without significant pigmental degeneration should also be considered if a patient presents with peripheral visual field constriction without other symptoms. The ophthalmologist should ensure that the location of the visual field defect matches the location of the lesion. In addition, a detailed fundus examination with macular optical coherence tomography can be helpful to diagnose such a lesion.
