ABSTRACT: A 20-year-old male patient presented at our clinic complaining of strange
visual experiences (neither decreased nor blurred) and a mild headache while reading. His best corrected visual acuity revealed
20/20 with a fort myopic correction. Intraocular pressures
measured with Dynamic Contour Tonometer (DCT) (Swiss Microtechnology AG, Port, Switzerland)
were 23.3 mmHg in the right eye (OD) and 27.4 mmHg in the left eye (OS) with cenral corneal
thicknesses (CCTs) of 588 (OD) and 591 (OS) microns, respectively. Optic
discs were bilateral pale with indistinct and scalloped margins without
cupping. Red free photos showed autofluorescence of both optic discs,
representative of optic disc drusen. Visual field analysis (VFA) of both eyes
revealed sensitivity depression with localized defects consistent with the
Optical Coherence Tomography (OCT) findings. Optic nerve head
drusen (ONHD), myopia and high intraocular pressures (IOPs), may cause ganglion cell damage resulting in RNFL thinning and visual
field loss. Because of the difficulty in detecting the exact cause and the
extent of the damage, patients with ONHD associated with high IOPs and myopia
should be examined closely with serial monitoring using OCT and VFA. In case of RNFL thinning and visual field defects, topical
antiglaucomatous therapy should also be determined.
