Summary
Retinitis pigmentosa (RP) patients often develop treatable conditions like cataracts and glaucoma. Early detection and management of these associated disorders are crucial to prevent severe vision loss in RP patients.
Area of Science:
- Ophthalmology
- Genetics
- Public Health
Background:
- Retinitis pigmentosa (RP) is a hereditary retinal degeneration with no current cure.
- Associated ocular conditions, such as cataracts and glaucoma, exacerbate vision loss in RP patients.
- This study addresses the lack of data on RP-related surgeries in Nigeria.
Purpose of the Study:
- To describe the clinical presentation of RP in Nigerian patients.
- To determine the prevalence of treatable ocular comorbidities in RP.
- To identify factors contributing to severe visual impairment and blindness in RP.
Main Methods:
- Retrospective review of 52 RP cases over three years at University College Hospital, Ibadan.
- Classification of RP into clinical types.
- Identification and evaluation of associated treatable eye conditions and visual impairment levels.
Main Results:
- RP accounted for 0.69% of new outpatient cases (52/7520).
- Cataracts were present in 34.5% and high intraocular pressure in 11.4%, often in couched eyes.
- Cataracts, age, and secondary glaucoma from couching were risk factors for severe visual disability.
Conclusions:
- Treatable ocular conditions are common in RP patients.
- Cataracts in RP patients, if untreated, can lead to complete blindness.
