⁴GATA Haydarpaşa Eğitim Hastanesi Göz Hastalıkları Servisi Şefi, İstanbul, Prof. Dr. A 25 years old male, who had been diagnosed as glaucoma and had been started topical anti-glaucomatous therapy two years ago, applied to our clinic for the sufficiency examination of obligatory military service. He was complaining of impaired vision. In the ophthalmologic examination, anterior segment and filtration angle were normal. In direct ophthalmoscopy, cup-to-disc ratios were 6/10 in the right and 4/10 in the left eye. Heidelberg Retinal Tomography (HRT-II) revealed a cup asymmetry between the two eyes. The intraocular pressures of the patient, who had not used his medications for a few months, were measured as 32 mmHg in right and 22 mmHg in left eye. The Humphrey perimetry revealed cloverleaf defects in both eyes. In the visual field test repeated after persuading patient to not malinger, the visual field was fully normal in the left eye and a nasal step defect was found in the right eye. The patient was warned about the severity of glaucoma and the topical anti-glaucomatous therapy was started again. As a result, the cloverleaf defect that has been found in malingering and exaggerating subjects should be known and evaluated cautiously by the clinicians who have to decide officially about the stage of glaucoma.
