Background: Retinitis pigmentosa (RP) is a genetic retinal disorder that leads to progressive visual impairment. Early symptoms are night blindness, followed by the loss of peripheral vision and constricted visual fields. The symptoms and signs worsen as time goes. Objectives: The objective of this study was to determine the incidence of RP among Sudanese students of Al-Neelain University College of Optometry and Visual Science from March to May 2017. Materials and Methods: In a cross-sectional observational hospital-based study, which was conducted at Al-Neelain University Eye Hospital, Gabrah, Khartoum, Sudan, in 3-month period, from March to May 2017, by a consecutive sampling technique, 193 Sudanese students from Al-Neelain University College of Optometry and Visual Science were examined for the presence of RP. Data were statistically analyzed using SPSS. Results: Females were 154 (79.8%) and males were 39 (20.2%). Their mean age was 21.76 years ± 2.5 years (range: 16–25 years). One hundred and forty-five (75.1%) students were between 21 and 25 years and 48 (24.9%) students were between 16 and 20 years. The majority (99.5%) reported negative symptoms of night blindness, and few (0.5%) reported definite positive symptoms of night blindness. Only 2 (1.0%) students out of the whole study group disclosed family history of RP. Sixty-one (31.6%) participants revealed consanguinity; 2 (1%) of them were of first-degree and one (0.5%) of second-degree consanguinity. One hundred and forty-three (74.1%) participants were emmetropic while fifty (25.9%) with minor degrees of ammetropia (±0.5–0.75 diopter). Overall, 188 (97.4%) scored 6/6 best-corrected visual acuity. None of the partinsepants students reviled any degree of color defect. Intraocular pressure in all students was within normal limits. No single student revealed fundus appearance of RP in all 193 candidates and even in those with symptoms of night blindness or family history of RP. Conclusion: No single RP case with typical fundus appearance and visual functional loss was reported in 193 male and female Sudanese students of Al-Neelain University College of Optometry and Visual Science.
