Patients’ general information.

Visual acuity of glaucomatous (GM) patients were tested with the use of Snellen charts (5 m for best corrected visual acuity/ uncorrected visual acuity (BCVA/UVA) and 30 cm for corrected near visual acuity/ uncorrected near visual acuity (CNVA/UNVA)) at the Mega-Lens Specialized Ophthalmology Clinic in Warsaw. The intra-ocular pressure (IOP) of glaucomatous patients was also measured in the clinic. Visual acuity of retinitis pigmentosa (RP) patient was tested at the Nencki Institute of Experimental Biology of the Polish Academy of Sciences in Warsaw with the use of Early Treatment Diabetic Retinopathy Study (ETDRS) charts (5 m for BCVA/UVA and 33 cm for CNVA/UNVA). Visual acuity results are expressed in Visus scale (also known as Snellen scale).
