Unilateral retinitis pigmentosa (RP) is rare condition and may occur due to genetic mosaism, which may affect only some cells, or develop somatic mutation instead of germinal mutation. A 28-year-old female patient who had had no history of systemic disease, trauma, drug use, or intraocular surgery had progressive vision loss and nyctalopia in her right eye. Her anterior and posterior segment examination revealed posterior subcapsular cataract and RP with lamellar macular hole (MH) in the right eye. Surgery was planned and after phacoemulsifi cation and intraocular lens implantation as well as pars plana vitrectomy with internal limiting membrane peeling, the lamellar MH was completely closed and the foveal contour is formed. Many macular abnormalities can be seen in unilateral RP cases. It is of great importance to detect these macular pathologies early to apply appropriate treatment and to prevent the addition of central visual fi eld to peripheral visual fi eld lost due to RP.

A 63-year-old Caucasian woman presented with the complaint of decreased visual acuity and metamorphopsia in her right eye. She was diagnosed with vitreomacular traction (VMT) and concurrent diabetic macular edema (DME). The patient’s best corrected visual acuity was 3/10 and central macular thickness (CMT) was 387 μm in the right eye. Intravitreal anti-VEGF injection was recommended for the treatment of symptomatic VMT with DME which did not show spontaneous improvement. One month later, her BCVA increased to 7/10 and VMT resolved (CMT decreased to 247 μm). Visual acuity and fundus fi ndings remained stable with no additional treatment during the one-year follow-up.
A 43-years old man presented with visual impairment in both eyes. In ophthalmological examination, visual acuity was found as 0.9 (Snellen charts) in right eye and fi nger counting at 2 meters in left eye. The patient could bilaterally read only 2 plates correctly in Ishihara Test for Color Defi ciency. In fundus examination, minimal parafoveal hypo-pigmented areas were observed in right eye while chorioretinal atrophy (approximately one disc area in size) with well-defi ned borders was seen in the left eye (Picture 1). On spectral domain optical coherence tomography (SDOCT, Spectralis OCT, Heidelberg Engineering, Heidelberg, Germany), foveal disorganization in outer layers and hyper-refl ective deposits over retinal pigment epithelium were striking at right eye. In left eye, all retinal layers were thinned at well-defi ned atrophy (Picture 2). In fundus autofl orescence (FAF), deposits seen in right eye showed hyper-autofl orescence while well-defi ned retinal atrophy area in left eye showed absolute hypo-autofl orescence (Picture 3). In pattern visual evoked potentials (VEP), P100 latency could not be determined since no wave was formed in both eyes. In fl ash VEP, waveforms were symmetrical in both eyes. The pattern electroretinography was subnormal bilaterally. In Ganzfi eld ERG, photopic and scotopic responses were subnormal. The scotopic INTRODUCTION
