To assess the kind and degree of retinitis pigmentosa, the patients were subjected to anterior segment examination, cover-uncover test, and pen torch examination. Data was analysed using SPSS 20.\nResults: Of the 25 patients with a mean age of 27.16 \u00b111.28 years, 16 (64%) were females. Overall, 15 (60%) patients were classified as blind, and 5 (20%) retained normal visual acuity. Nystagmus was present in 8 (32%) of the participants, predominantly among those with blindness (p= 0.377). Nystagmus was more frequent in females (6\/16; 37.5%) than males. However, the difference was not statistically significant (p=0.734).\nConclusion: Bilateral blindness was the predominant outcome, with nystagmus affecting nearly one-third of patients regardless of visual acuity.\nKey Words: Nystagmus, Patient, Retinitis pigmentosa.<\/jats:p>","DOI":"10.47391\/jpma.22493","type":"journal-article","created":{"date-parts":[[2026,5,31]],"date-time":"2026-05-31T19:23:10Z","timestamp":1780255390000},"page":"991-995","source":"Crossref","is-referenced-by-count":0,"title":["Frequency of nystagmus in retinitis pigmentosa patients"],"prefix":"10.47391","volume":"76","author":[{"given":"Maryam","family":"Hameed","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryam","family":"Mansha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maham","family":"Shabir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryam","family":"Iftikhar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Usama","family":"Elahi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mawra","family":"Zahid","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"26547","published-online":{"date-parts":[[2026,5,28]]},"container-title":["Journal of the Pakistan Medical Association"],"original-title":[],"link":[{"URL":"https:\/\/www.jpma.org.pk\/index.php\/public_html\/article\/download\/22493\/4834","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.jpma.org.pk\/index.php\/public_html\/article\/download\/22493\/4834","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,11]],"date-time":"2026-06-11T19:33:05Z","timestamp":1781206385000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jpma.org.pk\/index.php\/public_html\/article\/view\/22493"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,28]]},"references-count":0,"journal-issue":{"issue":"06","published-online":{"date-parts":[[2026,5,31]]}},"URL":"https:\/\/doi.org\/10.47391\/jpma.22493","relation":{},"ISSN":["0030-9982"],"issn-type":[{"value":"0030-9982","type":"print"}],"subject":[],"published":{"date-parts":[[2026,5,28]]}}}
