Summary
This case report details a rare instance of coexistent sectorial retinitis pigmentosa (RP) and optic disc pit (ODP) in a single eye. The findings highlight the importance of comprehensive retinal imaging for diagnosing complex visual impairments.
Area of Science:
- Ophthalmology
- Medical Case Reports
Background:
- Sectorial retinitis pigmentosa (RP) and optic disc pit (ODP) are individually rare retinal conditions.
- Co-occurrence of these conditions is exceptionally uncommon, presenting diagnostic challenges.
Purpose of the Study:
- To report the first documented case of coexistent optic disc pit and sectorial retinitis pigmentosa affecting the macula.
- To illustrate the diagnostic findings using multimodal imaging techniques.
Main Methods:
- Clinical examination including funduscopy.
- Multimodal imaging: fundus autofluorescence, spectral-domain optical coherence tomography (SD-OCT), fluorescein angiography (FA).
- Functional assessment using multifocal electroretinogram (mfERG).
Main Results:
- A 40-year-old female presented with decreased vision and sectoral RP affecting superior and inferotemporal macula.
- Optic disc pit identified at the temporal optic disc margin.
- Imaging confirmed pigmentary changes, reduced arterial caliber, and an atrophic foveal lesion.
Conclusions:
- This case represents the first description of coexistent optic disc pit and sectorial retinitis pigmentosa involving the macula in the same eye.
- The study underscores the utility of advanced imaging in characterizing rare ophthalmic conditions.
- Management was conservative due to poor visual prognosis from the foveal lesion.

01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
